This study aimed to determine the incidence of first-episode psychosis in Palermo, Sicily over a 3-year period. 204 participants experiencing first-episode psychosis were identified. The crude incidence of all psychoses was 15.9 per 100,000. The risk of schizophrenia was higher in males compared to females and in migrants compared to native Italians. This study confirms previous findings from Northern Italy that the risk of psychoses is much lower in Italian cities than reported in Northern Europe, and differences in incidence may provide clues about psychosis etiology.

Epidemiology of Tuberculosis (TB) in Albania 1998-2009iosrphr_editor
Abstract : In Albania, many people erroneously think that tuberculosis (TB) is a disease of the past-an illness
that no longer constitutes a public health threat. Surveillance is an integral part of tuberculosis (TB) control.
Albania has a highTB notification rate and there are doubts about underreporting. The evolution of the
incidence of tuberculosis is presented, together with more detailed figures over the period 1998-2009. These
figures were obtained by the monthly forms (called 14/Sh) compared with the individual notification data.
Objective: To examine the distribution and sources of increased tuberculosis (TB) morbidity and reporting
system deficiencies in the Albania from 1998 through 2009. Metodology: The study is descriptive one conductet
during the period 1998-2009. The statistical analysis is based on data reported from regional level (regional
epidemiological departments) to the central level (Public Health Institute). Results: The main findings were:
discordance between the collected data (individual form) and reported data (monthly form); tuberculosis
incidence rate shows little oscillations which ranges from 6.67 to 9.2 cases/100.000 population; 50% of the
regions show a lack of information on the confirmation of diagnosis and laboratory examination type used for
confirmation. Conclusion: TB disease in high-risk populations where it is difficult to detect, diagnose, and treat;
limitations of current control measures and the need for new tests and treatments, including an effective
vaccine; improving information system, regulation of individual form and personnel training.
This summary provides an overview of a retrospective study analyzing seasonal variation in cases of non-neonatal tetanus (NNT) over a 7-year period from 2004-2010 at a hospital in Jaipur, India. The study found that post-monsoon season had significantly more NNT cases than other seasons each year. Specifically, over one-third of total cases and deaths occurred in post-monsoon months of June-July and November-December. Additionally, winter season had the lowest number of cases but the highest case fatality rate of NNT. The study aims to better understand seasonal trends in NNT occurrence to help guide future elimination strategies.
The document discusses the COVID-19 outbreak in Italy. It summarizes the increasingly strict measures the Italian government has taken to limit citizens' movement and close public spaces. As of March 16th, there were over 27,000 confirmed cases in Italy, a rate of growth that has doubled over the past week. Data on patient characteristics and outcomes is still limited. Improved collection and sharing of surveillance data across countries is needed to better inform the response.

Dementia affects the whole person not just the brain and memory, but also a host of important aspects of daily life . The risk of developing dementia increases exponentially with age and global ageing means that in the next few decades very large numbers of people around the world will enter the age where the incidence of dementia will be highest. One of the biggest challenges of the 21st century seems to be Alzheimer disease (AD) together with other types of dementia.
The ageing of the population across Europe and beyond means that the number of people with dementia will grow in future decades with consequent implications for care provision, care burden and public expenditure. It is no wonder, therefore, that many countries are already preparing for the projected rise in the number of people with dementia by putting in place dedicated action plans and/or dementia strategies.

This document provides an overview of COPD (chronic obstructive pulmonary disease) with perspectives on future directions and a look at the past. It discusses topics like demographics, the negative outlook for smoking, noncommunicable diseases, clinical phenotypes, new technologies, and conclusions. The summaries highlight that efforts must continue against smoking and early diagnosis. Future consensus is needed on COPD definitions. Regenerative medicine offers hope but its realities are unknown. The aging phenotype will dominate COPD's future, and obesity comorbidity warrants clinical interest.
Deaths from Respiratory Diseases: Implications for end of life care in England
21 June 2011 - National End of Life Care Intelligence Network (NEoLCIN) / National End of Life Care Programme
The aim of this report is to analyse the latest data on place of death for those with respiratory disease and how this varies with gender, age, socioeconomic deprivation, place.
It presents high level analysis of mortality data from the Office for National Statistics(ONS).
Aids mortality before and after the introduction of highly active antiretroviralAna Paula Bringel
This study examines trends in AIDS mortality in Barcelona, Spain before and after the introduction of highly active antiretroviral therapy (HAART) in 1996 to determine if inequalities existed between socioeconomic groups. The results show that AIDS mortality increased until 1995 and then decreased after HAART was introduced. However, inequalities remained, as the lowest socioeconomic group consistently had higher AIDS mortality rates and risks of death compared to the highest group. A similar pattern was found among intravenous drug users. The persistence of inequalities after HAART suggests access to or adherence with treatment may be lower for people in lower socioeconomic groups.
This document analyzes EU surveillance data from 2009-2014 on shigellosis, a bacterial infection transmitted through contaminated food or water or directly from person to person through feces. The analysis found that domestically-acquired shigellosis cases increased over this period and accounted for over half of reported cases in 2014, with the proportion of cases among men doubling. Male-to-female ratios were highest among domestic cases, suggesting ongoing sexual transmission of certain Shigella strains like S. flexneri serotype 3a among men who have sex with men in Europe. The authors conclude countries should investigate domestic male cases and sexual transmission more and report such data to help monitor trends and facilitate public health interventions.

- The study analyzed data from 54 Italian hospitals on admissions for acute myocardial infarction (AMI) during a week in March 2020 during the COVID-19 outbreak vs. the same week in 2019.
- Admissions for AMI were reduced by 48.4% during the COVID-19 period. Specifically, admissions were reduced by 26.5% for ST-elevation MIs (STEMI) and 65.1% for non-ST-elevation MIs (NSTEMI).
- Case fatality rates for AMI increased substantially during the COVID-19 period, from 4.1% to 13.7% for STEMI patients. Major complications also increased.
Abstract—Epidemiological study of Rivers State University of Science and Technology Port Harcourt, Nigeria was carried out to identify the morbidity pattern in the University community in order to establish the current health status and trends. This study utilized secondary morbidity data sourced from Health Services Department. Data on staff mortality were obtained from the Personnel/Establishment Division. Methods employed for data collection were health records survey and data collection sheets. Morbidity information required were date, sex, age, department, card number and diagnosis of each case. Information required for each mortality case was date, sex, age, department, salary level and the cause of death. Of all cases of morbidity, communicable diseases comprised 17.5%; non-communicable diseases 24.1%, generalized disease symptoms 55.2% and others 3.2%. The study revealed that the leading causes of morbidity in the University were fever/headache/cold (36.9%), hypertension (13.6%), generalized body pain (7.5%), abdominal pain/vomiting (6.7%) and diabetes (4.9%). Hypertension emerged the second major cause of morbidity among the staff and males had higher rate of morbidity compared to females. It was also concluded that although mortality was increasing with time but there was no sex wise significant difference in mortality trend. It was recommended among others that Diabetes Mellitus and Hypertension being silent killers should be monitored regularly within the University community. Also the current practice of manual data entry should be replaced with computerized data system for better health records management.
This document reviews the relationship between suicidal behavior and alcohol abuse. It finds that alcohol use is highly associated with suicide in three ways: through its disinhibiting effects on suicide attempts and completions, by increasing suicide risk among those with alcohol use disorders, and through correlations found between alcohol consumption and suicide rates at population levels. The review examines evidence from studies searching medical databases on this topic. It finds that psychiatric disorders like depression and substance abuse are often linked to suicide cases. However, comorbid psychopathology is neither sufficient nor necessary to explain the relationship between alcohol and suicide.
Aim: Suicide is the leading cause of non-accidental death in Spain across both sexes and all age groups; however, data on suicide attempts by region are heterogeneous and little reported. This study aimed to examine the socio-demographic and epidemiological variables most
strongly related to suicide attempts in Jaén province.
Method: Data on people who had attempted suicide over a 26-month period (2009–2011) were collected from the emergency departments of two hospitals via their electronic medical record systems specific to the Autonomous Community of Andalusia (Spain). Descriptive and frequency statistics were obtained and the relationship among variables was examined.
Results: Suicide attempters were aged 24 to 53 years, being primarily women (65.25%). The most frequent suicide method was medication ingestion (85.55%); thus, ingestion of toxic substances has become the preferred method among women (LR(3) = 14.731; p = .02). The
hospitals discharged the patients (46.44%) or referred them to mental health services in the area (20.08%) following a suicide attempt. There were more hospital discharges when the attempt involved ingestion of toxic substances or self-harm (LR(12) = 20.603; p = .05), and in winter
and spring (LR(12) = 69.772; p < .001).
Conclusion: The need for emergency departments to have prevention and intervention procedures in place, specifically designed for suicide attempts and at-risk individuals, is discussed
Smoking and alcoholism: Risk factors for papillitis?BIJCROO
Introduction: Papillitis is the inflammation of the optic nerve at the level of the optic papilla or optic disc. We did
not find enough published studies that corroborate smoking and alcoholism as absolute risk factors for papillitis;
however, it has been raised, so we were motivated to conduct this research, with the aim of identifying a statistically
significant causal association between these factors and papillitis in our hospital.
Methodology: An analytical study of cases and controls was carried out in patients with papillitis treated at the
Ophthalmology Centre of Santiago de Cuba (2017–2019). Group 1 (cases): 42 patients; group 2 (controls): 84
patients’ companions who attended in the same period and did not present ophthalmological entities.
Results: In the association of smoking with papillitis, we obtained an odds ratio (OR) = 1.60, with confidence
interval (CI): [0.74; 3.48], but p > 0.05. Alcoholism with papillitis resulted in an association with OR = 1.19, with CI:
[0.53; 2.68] and p > 0.05.
Conclusion: In this study, smoking and alcoholism had no statistically significant causal association with papillitis.
This document summarizes a study on influenza-like illness (ILI) sentinel surveillance in Peru between 2006-2008. Over 6,800 patients with ILI were enrolled from clinics across Peru. Respiratory samples were tested and at least one virus was detected in 42.6% of samples. The most common viruses were influenza A (25.1%), influenza B (9.7%), and parainfluenza (3.2%). Genetic analysis found multiple lineages of influenza A and B circulating. This study characterized the viral causes of ILI in Peru and has implications for vaccine design and clinical treatment in South America.

CDC / EIS, 2003: Paralytic Polio in Ababo (891-903) – Student's Guide Page 2
PART I
It is the early 1990s. The World Health
Organization is planning a program for the
global eradication of polio by the year 2000.
Likura, a fictitious nation in south-central Africa,
may become one of the countries selected to
test the effectiveness of WHO's polio eradication
strategies. Unfortunately, little is known about
polio in Likura. The Minister of Health therefore
assigned the task of assessing the polio
situation to a Ministry worker who has recently
returned from an epidemiology course in
Atlanta, and who is about to become the District
Health Officer in the Ababo District. The Ababo
District is a relatively poor, rural district with a
single hospital and several health centers. The
Ababo District has attempted to conduct
surveillance on polio cases and deaths over the
past five years. The hospital, health centers,
and all health workers are supposed to report
such cases to the District Health Officer.
Question 1: What is incidence?
One measure of the polio situation in a
community is the prevalence of lameness in
children, since lameness is a common sequela
of polio.
Question 2: What is prevalence?
CDC / EIS, 2003: Paralytic Polio in Ababo (891-903) – Student's Guide Page 3
Question 3a: What data might you use (or collect) to determine the incidence of polio in the
population?
Question 3b: What data might you use (or collect) to determine the prevalence of the sequelae of
polio (lameness) in the population?
Question 4: What are the key elements included in the definition of public health surveillance?
Question 5: What is the difference between active and passive surveillance systems? Is the Ababo
surveillance system for polio passive or active?
CDC / EIS, 2003: Paralytic Polio in Ababo (891-903) – Student's Guide Page 4
PART II
To characterize the incidence of polio over time,
the new District Health Officer tabulated the
routinely collected surveillance records for the

Background; Social Class has shown relation with admissions at Emergency Departments. To assess whether there is a relationship between the level of triage and the social class of patients who attend the emergency department and whether there are other variables that can modulate this association. Methods Observational study with 1000 patients was carried out between May and July 2018 in the Emergency Department of the University Hospital Arnau de Vilanova in Lleida. Sociodemographic variables such as age, gender, country of origin and marital status were analyzed. The triage level and the main explanatory variable was social class. Social class was calculated based on the CSO-SEE 2012 scale. Results 49.4% were male and the average age was 51.7 years. Most of the patients (66.6%) attended the emergency department under their own volition and the most common triage levels were level III or Emergency (45%). There is a significant relationship between age and triage level. The younger patients had a lower triage level (p <0.001). The percentage of patients with lower social class who attended the emergency department for minor reasons was 42% higher compared to the rest of the patients (RR = 1.42; 1.21-1.67 95% CI, p <0.001). Conclusions; Patients with a lower socioeconomic class go to the Emergency Department for less serious pathologies.
The document summarizes HIV/AIDS in Ethiopia across multiple topics:
1) HIV incidence in adults is estimated at 0.06% annually, corresponding to around 7,000 new cases, though a lower estimate is 0.05% or 6,000 new cases using a different method. Incidence is highest in those aged 50-64.
2) Ethiopia has made progress toward global 90-90-90 targets, with an estimated 82% of people with HIV knowing their status, 74% on antiretroviral treatment, and 66% virally suppressed.
3) Key populations include female sex workers, prisoners, divorced/widowed urban women, and long-distance drivers.
Imperial college covid19 europe estimates and npi impactValentina Corona
The document summarizes estimates from a model analyzing COVID-19 mortality data from 11 European countries. Key findings include:
- Millions of infections have likely occurred, far more than the number detected. Italy may have had 5.9 million infections (9.8% of population) as of March 28th.
- Non-pharmaceutical interventions have likely reduced the reproduction number (Rt) substantially, though estimates vary by country. On average, interventions represent a 64% reduction from initial Rt of around 3.87.
- Interventions may have averted 59,000 deaths by March 31st across the 11 countries. More data is needed to determine if Rt has been driven below 1 in

The Australian government identifies national health priorities based on several key principles:
1. Principles of social justice - including supporting vulnerable groups and allocating resources fairly.
2. Prevalence and burden of health conditions - considering conditions that affect many people or have high costs.
3. Potential for prevention and early intervention - targeting modifiable risk factors and improving health behaviors.
4. Cost to individuals and communities - both the financial and non-financial impacts of diseases.
Priority groups identified include Aboriginal and Torres Strait Islanders, those in rural/remote areas, and low socioeconomic groups experiencing health inequities. Data on disease rates, mortality, and morbidity help determine the most significant health issues facing Australia.

and spring (LR(12) = 69.772; p < .001).
Conclusion: The need for emergency departments to have prevention and intervention procedures in place, specifically designed for suicide attempts and at-risk individuals, is discussed
Smoking and alcoholism: Risk factors for papillitis?BIJCROO
Introduction: Papillitis is the inflammation of the optic nerve at the level of the optic papilla or optic disc. We did
not find enough published studies that corroborate smoking and alcoholism as absolute risk factors for papillitis;
however, it has been raised, so we were motivated to conduct this research, with the aim of identifying a statistically
significant causal association between these factors and papillitis in our hospital.
Methodology: An analytical study of cases and controls was carried out in patients with papillitis treated at the
Ophthalmology Centre of Santiago de Cuba (2017–2019). Group 1 (cases): 42 patients; group 2 (controls): 84
patients’ companions who attended in the same period and did not present ophthalmological entities.
Results: In the association of smoking with papillitis, we obtained an odds ratio (OR) = 1.60, with confidence
interval (CI): [0.74; 3.48], but p > 0.05. Alcoholism with papillitis resulted in an association with OR = 1.19, with CI:
[0.53; 2.68] and p > 0.05.
Conclusion: In this study, smoking and alcoholism had no statistically significant causal association with papillitis.
This document summarizes a study on influenza-like illness (ILI) sentinel surveillance in Peru between 2006-2008. Over 6,800 patients with ILI were enrolled from clinics across Peru. Respiratory samples were tested and at least one virus was detected in 42.6% of samples. The most common viruses were influenza A (25.1%), influenza B (9.7%), and parainfluenza (3.2%). Genetic analysis found multiple lineages of influenza A and B circulating. This study characterized the viral causes of ILI in Peru and has implications for vaccine design and clinical treatment in South America.

PART I
It is the early 1990s. The World Health
Organization is planning a program for the
global eradication of polio by the year 2000.
Likura, a fictitious nation in south-central Africa,
may become one of the countries selected to
test the effectiveness of WHO's polio eradication
strategies. Unfortunately, little is known about
polio in Likura. The Minister of Health therefore
assigned the task of assessing the polio
situation to a Ministry worker who has recently
returned from an epidemiology course in
Atlanta, and who is about to become the District
Health Officer in the Ababo District. The Ababo
District is a relatively poor, rural district with a
single hospital and several health centers. The
Ababo District has attempted to conduct
surveillance on polio cases and deaths over the
past five years. The hospital, health centers,
and all health workers are supposed to report
such cases to the District Health Officer.
Question 1: What is incidence?
One measure of the polio situation in a
community is the prevalence of lameness in
children, since lameness is a common sequela
of polio.
Question 2: What is prevalence?
CDC / EIS, 2003: Paralytic Polio in Ababo (891-903) – Student's Guide Page 3
Question 3a: What data might you use (or collect) to determine the incidence of polio in the
population?
Question 3b: What data might you use (or collect) to determine the prevalence of the sequelae of
polio (lameness) in the population?
Question 4: What are the key elements included in the definition of public health surveillance?
Question 5: What is the difference between active and passive surveillance systems? Is the Ababo
surveillance system for polio passive or active?

Background; Social Class has shown relation with admissions at Emergency Departments. To assess whether there is a relationship between the level of triage and the social class of patients who attend the emergency department and whether there are other variables that can modulate this association. Methods Observational study with 1000 patients was carried out between May and July 2018 in the Emergency Department of the University Hospital Arnau de Vilanova in Lleida. Sociodemographic variables such as age, gender, country of origin and marital status were analyzed. The triage level and the main explanatory variable was social class. Social class was calculated based on the CSO-SEE 2012 scale. Results 49.4% were male and the average age was 51.7 years. Most of the patients (66.6%) attended the emergency department under their own volition and the most common triage levels were level III or Emergency (45%). There is a significant relationship between age and triage level. The younger patients had a lower triage level (p <0.001). The percentage of patients with lower social class who attended the emergency department for minor reasons was 42% higher compared to the rest of the patients (RR = 1.42; 1.21-1.67 95% CI, p <0.001). Conclusions; Patients with a lower socioeconomic class go to the Emergency Department for less serious pathologies.
The document summarizes HIV/AIDS in Ethiopia across multiple topics:
1) HIV incidence in adults is estimated at 0.06% annually, corresponding to around 7,000 new cases, though a lower estimate is 0.05% or 6,000 new cases using a different method. Incidence is highest in those aged 50-64.
2) Ethiopia has made progress toward global 90-90-90 targets, with an estimated 82% of people with HIV knowing their status, 74% on antiretroviral treatment, and 66% virally suppressed.
3) Key populations include female sex workers, prisoners, divorced/widowed urban women, and long-distance drivers.

The Australian government identifies national health priorities based on several key principles:
1. Principles of social justice - including supporting vulnerable groups and allocating resources fairly.
2. Prevalence and burden of health conditions - considering conditions that affect many people or have high costs.
3. Potential for prevention and early intervention - targeting modifiable risk factors and improving health behaviors.
4. Cost to individuals and communities - both the financial and non-financial impacts of diseases.
Priority groups identified include Aboriginal and Torres Strait Islanders, those in rural/remote areas, and low socioeconomic groups experiencing health inequities. Data on disease rates, mortality, and morbidity help determine the most significant health issues facing Australia.

Abstract
Purpose—The incidence of psychotic disorders varies in different geographical areas. As there
have been no reports from Southern Italy, this study aimed to determine the incidence rate of first
episode psychosis in Palermo, Sicily.
Methods—All patients, aged 18-65 years, presenting with a first episode of psychosis (FEP)
(ICD-10 F20-F29, F30-F33) to mental health services in Palermo, were recorded over a 3-year
period. Incidence rates of psychotic disorders and their 95% confidence intervals (95% CI) were
estimated. Poisson regression was applied to estimate the differences in incidence rate ratio (IRR)
by age, sex and migrant status.
Results—Two hundred and four FEP participants were identified during the three years; 183
(89.7%, males n=112) participants were native Italians and 21 were migrants (10.3%, males
n=14). The crude incidence of all psychoses was 15.9 (95% CI 13.7-18.1). As predicted, the risk
of schizophrenia F20 was higher in males compared to females (adjusted IRR=1.99, 95% CI
1.36-2.88) and in migrants compared to native Italians (adjusted IRR= 4.02, 95% CI 2.39-6.75).

2. Conclusions—This study, the first from Sicily, confirms previous findings from Northern Italy
that the risk of schizophrenia and other psychoses is much lower in Italian cities than those
reported from cities in Northern Europe; the reasons for this disparity may provide important clues
to the aetiology of psychosis.
Keywords
psychosis; schizophrenia; incidence; Italy
1 Introduction
For many years it was thought that schizophrenia had a uniform distribution worldwide [1].
However, this “myth” was challenged by the systematic review by McGrath and colleagues
who, examining 158 studies from 32 different countries in the world, reported a wide range
of the incidence of schizophrenia of 7.7 to 43.0 per 100,000 across different countries [2].
Obtaining accurate epidemiological data is crucial for local mental healthcare planning in
different countries. Furthermore, knowledge of incidence variations between different
countries may facilitate our understanding of the distribution of risk factors for psychosis,
thus influencing prevention strategies. Most of the literature on the epidemiology of
psychosis in Europe comes from Northern countries [3–6]. For example, the Aetiology and
Ethnicity in Schizophrenia and Other Psychoses (AESOP) study, an incidence study across
three cities in UK, reported an incidence of psychoses of 32.1 per 100,000 persons years [6].
There are no epidemiological data on psychosis in Southern Italy, and no studies have ever
been carried out in Sicily; the few available Italian studies on this topic have been carried out
in the North which is quite different in terms of demographic and socioeconomic
circumstances. A study based on data collected by the South-Verona Psychiatric Case
Register (PCR), reported an incidence of schizophrenia and other functional psychoses (ICD
9 criteria [7]) of 10 per 100,000 person per year [8]. Another case register study conducted
in Portogruaro, in north-eastern Italy, based on first ever contact with psychiatric services,
reported an incidence rate for schizophrenia and for other related functional psychoses
(diagnosed according to ICD 9 criteria) of 17 per 100,000 per year [9].
Preti and Miotto [10] reported first admission rates to Italian psychiatric wards of patients
affected by schizophrenia, affective psychoses and other non-affective psychoses according
to data published by the Italian National Institute for Statistics (ISTAT) in the health-care
statistics yearbooks. Rates of schizophrenia ranged from 6 to 8.8 per 100,000 persons per
year, rates of other non-affective psychoses ranged from 5.7 to 7.8 per 100,000 persons per
year, and rates of affective psychoses from 3.3 to 8 per 100,000 persons per year. These are
lower than the median incidence of schizophrenia reported by McGrath et al [2]) and by
Kirkbride et al. [11].
The above studies did not involve interviews to confirm diagnosis. However, recently, two
first episode studies have come from Northern Italy. The first is the Bologna FEP study, an
8-year prospective study, which reported an incidence of 16.4 per 100,000 for psychotic
disorders diagnosed according to ICD 10 criteria [12], 7.3 per 100,000 for schizophrenia, 1.7

3. per 100,000 for affective psychoses, and 11.3 per 100,000 for other non-affective psychoses
[13].
The second is the Psychosis Incident Cohort Outcome Study, a multi-site population based
first episode psychosis study conducted in the Veneto region. The authors found an
incidence of psychotic disorders (according to ICD 10 criteria) of 18.1 per 100,000 per year.
Incidence rates were 5.6 per 100,000 per year for schizophrenia, 3.8 per 100,000 per year for
affective psychoses, 14.3 per 100,000 per year for other non-affective psychoses [14].
Thus, while accurate estimates of the incidence of psychotic disorders in Northern Italy
exist, there is a dearth of literature available from Southern Italy, which differs greatly along
cultural, socio-demographic and economic dimensions. In particular, Northern Italy is
wealthier and more extensively industrialised than the South. For example, the overall
unemployment rate in Italy in 2014 was 13.6%, but this rose to 21.7% in the South of Italy
[15]. For this reason, non-Italian migrants, tend to settle in northern Italy (1.356.937 in
North-West, 36.0%; 1.066.393 North-East, 28.3%) as opposed to southern Italy (338.871,
9.0%) or the Islands (Sicily and Sardinia: 140.655, 3.7%) [16].
It is important to establish whether or the low rates of psychosis reported from small
prosperous cities in Northern Italy are shared by a much larger city in the poorer South. The
aims of the present study were therefore: 1) to estimate the incidence of new cases of first
episode psychosis presenting to Mental Health Services in Palermo, the capital of Sicily,
over a three year period; 2) to identify subgroups at higher risk of psychoses (e.g. migrants
versus native Italians, males versus females). We expected to find similarly low incidence
rates of psychoses to those reported in other Italian sites [14,15] and to detect increased risk
of psychosis in the male and migrant subgroups, findings that have been widely reported.
The study methodology was closely based on that of the AESOP study carried out in the UK
[6,17] in order that the data would be directly comparable.
2 Methods
2.1 Catchment area
The catchment area included the whole city of Palermo. Palermo is served by a number of
mental health services: all inpatient units (five), private psychiatric hospitals (four) and
outpatient services (five) were examined in order to identify all new cases of psychosis in
Palermo.
2.2 Population at risk
The population at risk was defined as all the people resident in Palermo between 1 May
2008 to 30 April 2011 aged 18-65 years. Data were obtained from the 2011 census of Italy
conducted by the National Institute of Statistics (ISTAT) [18].
We use the term migrants to refer to those people who were born outside Italy independently
of whether or not they have Italian citizenship. According to ISTAT, in 2011 there were a
total of 427,913 residents aged 18-65 (207,552 males and 220,361 females) in Palermo. The
population was largely homogenous in terms of ethnicity; it was mostly people who were

4. born in Italy (n=412,771, 96.5%; males n=199,952, 48.4%); migrants (non-Italy born
people) represented only 3.5% (n=15,142 males=7,600, 50.2%). The population
denominator was multiplied by 3 to account for the 3-year study period leading to a total of
1,283,739 person-year at-risk.
2.3 Case ascertainment and assessment
Participants were people resident in the catchment area, referred to any mental health service
of Palermo for a first episode of psychosis (FEP) between 1 May 2008 and 30 April 2011.
The inclusion criteria were: 1) aged between 18-65 years; 2) residence in the catchment
area; 3) presence of any psychotic symptoms such as delusions, hallucinations, thought
disorder, bizarre or disturbed behaviour, negative symptoms, or mania; 4) absence of
previous contact with psychiatric services for psychotic symptoms; 5) absence of an organic
cause of psychosis, severe learning disability, or psychotic symptoms due to acute
intoxication 6) diagnosis of ICD-10 criteria for schizophrenia (F20), other non-affective
psychoses (F21-29) or affective psychoses (F30-33) [12].
Mental health services were contacted on weekly basis and clinical notes were regularly
checked, in order to identify all new admissions or new contacts for a first episode of any
psychotic disorder. Patients who were eligible were invited to participate in the study and to
complete the diagnostic assessment. For those who refused or were unavailable (i.e. having
been discharged), it has been used the ethical approval to record anonymous clinical and
socio-demographic data, according to the authorization to process personal data for scientific
research purposes anonymously [19]. To reduce the risk of missing patients, at the end of the
study period, a leakage study was conducted in all the mental health services in order to
detect cases of psychosis fulfilling the inclusion criteria, who could have been missed by the
initial screen. Patients who consented to participate in the whole assessment were assessed
using the Schedules for Clinical Assessment in Neuropsychiatry (SCAN) [24], while clinical
data of participants who refused or were not available to be interviewed were recorded using
the only SCAN Item Group Checklist (IGC) section. Main socio-demographic data was
collected using the Modified version of the Medical Research Council (MRC) socio-
demographic scale [21]. The diagnosis of psychotic disorder was made according to ICD-10
criteria [12] using all the available information and then confirmed case by case by
consensus meetings among two psychiatrists and two trainees in psychiatry according to the
Diagnostic Criteria for Research of the ICD-10 (DCR-10) [22].
2.4 Statistical analysis
Crude incidence rates and their 95% confidence intervals (95% CI) were estimated for
overall psychotic disorders and for each diagnostic category by gender and by migration
status. Age (9 bands, 18-24 to 60-65) and gender stratified incidence rates were also
estimated. Rates were presented per 100,000 persons per year. Poisson regression was used
to estimate the differences in incidence rate ratio (IRR) in different groups in the sample, i.e.
males versus females (adjusting for age and migration) and migrants versus native-born
Italians (adjusting for age and sex). We did not include any interaction terms in these models
because no statistical interaction was found between either age and migration, or age and
gender, following Likelihood Ratio Tests (LRT) (data not shown).

5. 2.5 Ethics
The study was approved by the Ethical Committee of the Palermo University Medical
School. The Department of Mental Health of Palermo (ASP 6) authorized epidemiological
data collection in the mental health services of Palermo. It has been performed in accordance
with the ethical standards of the Declaration of Helsinki and its later amendments.
3 Results
Two hundred and four patients met the inclusion criteria over the study period. 68 (33.3%)
FEP were assessed by face-to-face interviews, while 136 (66.7%) were assessed by clinical
notes and information gained from their care coordinators. 72 (35.3%) of the 204 cases
refused to be interviewed and 64 (31.3%) were identified by the leakage study. The main
reasons for refusing to be enrolled were lack of interest in the research and the fear of being
stigmatized.
There were no significant differences in terms of gender, migration, ethnicity, level of
education between participants who were recruited and those who refused or who were
identified retrospectively. There was a difference in mean age at first contact: non-recruited
cases were younger at their first contact.
Of 204 patients, 183 (89.7%, males n=112, 88.9%) cases were native Italians and 21 were
migrants (10.3%, males n=14, 11.1%). The main socio-demographic features of the sample
are displayed in Table 1.
3.1 Diagnosis
The majority of the cases met ICD-10 criteria for the diagnosis of F20 schizophrenia
(n=123, 60.3%), 19 (9.3%) for F30-33 affective psychoses, 62 (30.4%) for other non-
affective psychoses F21-29. The affective psychosis (F30-33) category was composed of 12
(63.1%) people affected by mania or bipolar disorder and 7 (36.9%) people by depression
with psychotic symptoms. There were no differences in diagnosis distribution by gender
(χ2=2.25, df=2, p= 0.325).
17 migrants (80.95%) were diagnosed with schizophrenia, 4 (19.05%) were diagnosed with
other psychosis.
3.2 Age at first contact with mental health services
Median age at first contact with psychiatric services for all psychoses was 28 years (IQR:
22-38). There was a difference in the distribution of age of onset across diagnostic categories
(Kruskal Wallis’ χ2=12.5, df=2, p=0.002) as shown in Table 2. There was no difference in
median age at first contact between schizophrenia (F20) and affective psychoses (F30-33)
(Kruskal Wallis’ χ2=0.10, df=1, p=0.714). Participants affected by other non-affective
psychoses (F21-29) were significantly older than those affected by schizophrenia (F20)
(Kruskal Wallis’ χ2=12.1, df=1, p<0.001).
Median age at first contact for overall psychoses was significantly higher in females 32.5
(IQR: 24-40) than males 26.5 (IQR: 22-35) (Wilcoxon’s z=2.3, p=0.020). The difference by

6. gender in median age at first presentation was no longer significant when the analyses were
repeated for each diagnostic category, presumably due to loss of power (Table 2).
Median age at first contact for all psychotic disorder was significantly different between
native Italians (29, IQR:23-39) and migrants (25, IQR:20-30) (Wilcoxon’s z=2.0, p=0.049).
3.4 Specific incidence rates by age bands, gender, and diagnostic category
Incidence rates of all psychotic disorders were stratified by age bands. The incidence of all
psychotic disorders peaked before 30 years old. After stratifying by age and gender, males
showed higher specific rates than females for all psychoses until 30-34 years; from 35-39
rates tended to overlap (Figure 1). When considering the distribution of age by gender for
schizophrenia, rates tended to overlap from 40-44 years old.
The total crude incidence of all psychoses was 15.9 (95% CI 13.7-18.1). Table 3 shows
incidence rates for all psychoses and by diagnostic categories. Following multivariable
Poisson regression, men had an increased risk of all psychotic disorders (adjusted IRR=1.67,
95% CI 1.26-2.23) compared to females, after adjustment for age and migrant status.
However, further inspection of separate diagnostic outcomes revealed that this pattern was
only observed for schizophrenia (adjusted IRR=1.99, 95% CI 1.36-2.88).
3.5 Incidence rates of psychosis in migrants
Although migrants totalled only 21 people, their proportion exceeded that in population at
risk (10.3% vs. 3.5%, χ2=27.3, df=1, p<0.001).
Among migrant cases, 7 were white Caucasians from Eastern Europe, 7 came from Asia,
and 7 came from Africa. There were no differences in the proportion of males and females
between native-born Italians and migrants. No migrant received the diagnosis of affective
psychosis (mania and depressive psychosis).
Table 4 shows crude incidence rates and their 95% CI for native-born Italians and for
migrants for all psychoses and by diagnostic category. Migrants had a nearly 3 fold
increased risk of any psychotic disorder (adjusted IRR= 2.78, 95% CI 1.76-4.39) and a 4
fold increased risk of schizophrenia (adjusted IRR= 4.02, 95% CI 2.39-6.75) compared to
native-born Italians, after adjustment for age and sex. No difference in risk was found for
other psychotic disorders.
4 Discussion
4.1 Main findings
The crude incidence rate of all psychotic disorders in Palermo was estimated 15.9 per
100,000 persons per year (95% CI 13.7-18.1) and the incidence of schizophrenia 9.6 (95%
CI 7.9-11.3); rates of affective psychoses were lower than those of other non-affective
psychoses. As expected, males had an increased risk of schizophrenia. Migrants had an
increased risk of schizophrenia but not of other psychoses.

7. 4.2 Comparison with previous Italian studies
Previous studies carried out in Northern Italy reported similar rates but these rates are not
directly comparable because of a different methodology. The Bologna FEP study, carried out
in three mental health services of West Bologna, found an overall median incidence rate for
all psychotic disorders that is similar to that we found in Palermo [13]. These rates are not
totally comparable because the BoFEP included in their sample substance-induced
psychoses that were excluded in the present study. Furthermore, no standardization was
applied in order to adjust for potential differences in the population structure between the
two sites. Taking into account these methodological limitations, no striking differences in
the rates of overall psychoses, schizophrenia and, affective psychosis between Palermo and
Bologna can be observed, although the incidence rate of other non-affective psychoses
seems to be higher in Bologna than in Palermo.
The Psychosis Incident Cohort Outcome Study carried out in the Veneto region [14]. Again,
a direct comparison between the two studies was not allowed by the differences in
methodology (e.g. age of first episode recruitment, inclusion of substance induced
psychosis) and the rates are not strictly comparable due to the lack of standardization to
control for the differences in the two population structures. However, again the rates of
schizophrenia in Veneto are similar to those we found in Palermo though there were higher
rates of other non-affective psychoses and of affective psychoses and lower rates of
schizophrenia when compared to Palermo.
4.3 Increased incidence of psychosis amongst males and migrants
The risk for schizophrenia was significantly influenced by gender. Males had a higher risk of
schizophrenia compared to women. This result is consistent with previous FEP studies
reporting an increased risk of developing psychoses and schizophrenia in males [2,6,13].
Gender differences in schizophrenia might reflect the differential proneness of men and
women to two different subtypes of schizophrenia presenting in different stages of life. One
suggestion is that men are more vulnerable to a neurodevelopmental form of the disorder
while women are more likely to develop a later onset psychotic disorder with an affective
component [23]. Other explanations suggest that more women than men have onset later in
life due to the declining of the protective effect exerted by oestrogens [24] or due to
psychosocial precipitating factors [25].
No differences in the risk by gender were found for affective psychoses as reported by some
previous studies [6].
Migrants represented a small proportion (10.3%) of the Palermo first episode sample than in
Bologna (23.9%) and in Veneto (22.8%). This is because of the higher migration rates in
Northern Italy. According to the last census data (2011) 86.5% of migrants were residents in
the North of Italy [16]. Sicily is sadly famous for the recent Mediterranean migrant crisis,
but at the time of this study, it did not represent an attractive destination for people who were
looking for a job because of the high rate of unemployment.

8. The present study confirms previous findings about the association between migration and
an increased risk of schizophrenia. Migrants were 4 times more likely to be affected by
schizophrenia compared to native Italians. These results are similar to those in the Bologna
study. Tarricone and colleagues [26] found a higher risk of developing psychoses in migrants
compared to natives (IRR= 2.5; 95% CI 2.1-2.9) and an increased risk of schizophrenia
(IRR=3.4; 95% CI 3-3.8). An increased risk of overall psychosis in migrants (IRR=2.7; 95%
CI 1.8– 2.7) was also reported in the Veneto study [14]. In our study no migrant received the
diagnosis of affective psychosis and, although the proportion of migrants was small, this
raises the possibility that, despite using standardised methods for the diagnostic assessment,
it is more difficult to detect the affective component of psychosis in migrants because of
cultural barriers.
4.4 Limitations
The present study has a number of limitations. One of the most important issues in
epidemiological studies is the accuracy of the case ascertainment. Every effort was made to
detect all the patients affected by psychosis during the three-year period. All the mental
health services of the catchment area were included in the study together with private
psychiatric hospitals and after the recruitment period a leakage study was conducted in order
to detect any missing cases. However this study is based on treated cases so that it is possible
that we failed to detect those people affected by psychosis who did not look for psychiatric
care. Ideally, population-based studies may lead to more accurate estimates of incidence
rates.
Comparisons among other Italian epidemiological data are provided descriptively. However,
a true comparison with other Italian cities should take into account the differences in the
population structure across sites.
The present study replicate previous findings about migration being a risk factor for
psychosis, however it does not allow to draw definite conclusions about psycho-social
factors which potentially mediate the increase in risk.
4.5 Strengths
This work is the first epidemiological study into psychosis ever carried in Sicily. It provides
data from the south of Italy, thus widening the information available on the different
geographical distribution of psychotic disorder. The diagnosis in participants was performed
by standardized methods which are directly comparable to the AESOP study. It provides
data on psychosis other than schizophrenia which are less explored in the literature.
Population denominator data were extracted by the 2011 census, the most reliable source of
population information and the Post Enumeration survey run by the National Institute of
Statistics in 2012 confirmed the accuracy of data [27].
5 Conclusions
This epidemiological study of psychosis, the first to be carried out in a large city from
Southern Italy shows roughly similar incidence rates of psychosis to two studies from
smaller cities and their surroundings in Northern Italy. As expected males and migrants

9. show increased rates. However, it is noticeable the incidence rates in all three Italian studies
are much lower than those reported in the AESOP study which was carried out using similar
methodology in the UK.
It is likely that the higher rates of migration into London contributes to the higher incidence
there, as reported in the AESOP study, compared to Palermo. Another interesting question
concerns the potential protective role of the family in psychosis onset and outcome. In this
study we did not specifically examine this issue. However, in a subsample of about one third
of our cases, 94.6% lived with someone else at the time of psychosis onset and only 5.4 % of
cases lived alone. In Northern European countries, as for example in the AESOP study,
people suffering their first episode of psychosis were more likely to live alone (43%) and to
have few close relationships [28]. However, incidence rate differences among different
countries are not likely to be explained by a single factor. It is more probable that multiple
environmental factors such as social isolation, urbanicity, migration and substance
consumption interact with biological and genetic factors in modulating the risk of psychoses.
Multi-centric epidemiological and case control studies are needed to describe incidence
patterns in Europe and to further explore the role of putative risk factors for psychotic
disorders. Further studies to address the causes of these differences are urgently needed.
