This study analyzed 3,615 patients who tested positive for COVID-19 at a large New York City hospital system between March 4-April 4, 2020. The researchers found that among patients under 60 years old, those with a BMI between 30-34 were twice as likely to be admitted to the hospital and 1.8 times as likely to require critical care compared to those with a BMI under 30. Patients under 60 with a BMI over 35 were 2.2 times as likely to be hospitalized and 3.6 times as likely to need critical care, indicating that obesity is an under-recognized risk factor for worse COVID-19 outcomes in younger patients.

Background: Tuberculosis is one of the most ancient infectious diseases caused by Mycobacterium tuberculosis. The population most affected is the young and economically productive one. The social factors include poor quality of life, poor housing, overcrowding, population explosion, under nutrition, lack of education, and last but not the least lack of awareness of cause of illness.
Aims and Objectives:
1. To study the clinical presentation of tuberculosis in patients.
2. To study various risk factors of tuberculosis.
Material and Methods: This study was conducted at selected designated microscopic centre (DMCs) Kanpur Nagar district has a population of 45.73lakh ( Census 2011).All the patients who were registered in the selected DMCs in the last one month of the year 2016 ( between April and May) were taken into consideration for the present study. Data was collected on predesigned and pretested questionnaire using direct personal interview method of patients at DMCs on the DOTS days of the week i.e Monday, Wednesday and Friday. Informed consent of the study subjects was taken before interview. A total of 105 registered patients were interviewed personally and also the treatment card of patients was obtained from their respective DMCs.
Results: Out of 105 cases of tuberculosis which reported at DMCs maximum no. of patients belongs to age group between 21-40 yrs of age group (58%). Majority of cases were married (65.7%) cases. (62%) cases were Hindu by religion and (58%) belongs to other backward caste. In the study we found majority of patient was illiterate (34.3%). Most common clinical presentation was cough, fever and cough with expectoration, anorexia was reported in (61.9 %) of cases (77%) were cigarette/bidi smokers, 60% were tobacco chewer. Diabetes was reported in (12.4%) cases and (3.8%) cases were HIV positive.

ABSTRACT
Objective: To determine the frequency of hepatitis C virus infection in patients with type 2 diabetes mellitus and to look for the common risk factors leading to this infection in diabetics. Study Design: Descriptive cross sectional study design. Place and Duration of Study: Department of Medicine, Combined Military Hospital (CMH) Kharian, from Jan 2015 to Jun 2015. Patients and Methods: This study was conducted in the department of Medicine, Combined Military Hospital Kharian. Through a descriptive cross sectional study design, a total of 140 patients with type 2 diabetes mellitus, admitted through casualty, OPD or private clinics were selected and tested for Hepatitis C virus infection. The common risk factors leading to such infection among positive cases were also scrutinized. Results: The mean age of patients was 48.82 ± 10.14 with 60.7% female gender predominating the overall sample of diabetics. Using 3rd generation ELISA method, hepatitis C virus was found in 45 (32.1%) of patients with 41-50 years of age group most commonly affected age group (34.7%) and female (57.8%) commonly affected gender. The distribution of risk factors leading to hepatitis C virus in diabetics are: 21 (46.7%) had history of surgery in the past, 13 (28.9%) had history of blood transfusion in the past, 7 (15.55%) had history of hemodialysis while only 4 (8.9%) had history of tattooing in the past. Conclusion: Hepatitis C virus infection is still a common problem in diabetic patients of our local population and we recommend further research work over its risk factors so that the guidelines for its control may be formulated.

Assessment of Zooplankton Diversity in Kosavampatti Lake at Namakkal District...BRNSS Publication Hub
Kosavampatti Lake is a historical lake situated in Namakkal district. A lake usually helps in recharging groundwater, and the trees in and around the lake serve as a nesting place for birds. Zooplankton is the vital constituents of water flora which aids as the main component of the aquatic food chain. It sustains appropriate equilibrium between biotic and abiotic components of the water ecosystem. The present study aimed to deal with zooplankton diversity in Kosavampatti Lake. The investigation was carried out for 1 year, i.e., October 2017–September 2018. During the study period, the zooplankton population of Kosavampatti Lake water is characterized by five various classes, namely Protozoa, Cladocera, Copepoda, Ostracods, and Rotifera, with 19 different species which were noted and documented in Kosavampatti Lake. The main classes of Rotifera are the highest groups among zooplankton and the density of zooplankton community was higher in summer and lesser in monsoon. The results of various kinds of diversity indices strongly indicate that Kosavampatti Lake is absolutely polluted in nature.

Incidence of Hepatitis B virus among healthy asymptomatic students in Gombe State University was determined, this was in an effort of providing baseline data on the diseases burden, and the possible risk factors associated with the infection in the study population. A total of 100 serum samples were collected from volunteers and screened using rapid immune chromatographic test kits for Hepatitis B surface antigen (HBsAg). The study revealed that 14% were HBsAg positive. The highest incidence rate of 18.2% (12) was recorded among the age group of 16-25 years, and males recorded the highest incidence rate of 20% (12), indicating that gender but not age might have greater influence on the infection (P= 0.05).

The severity and mortality of COVID 19 cases has been associated with the Three category such as vaccination status, severity of disease and outcome. Objective presently study was aimed to assess the severity and mortality among covid 19 patients. Methods Using simple lottery random method 100 samples were selected. From these 100 patients, 50 patients were randomly assigned to case group and 50 patients in control group after informed consents of relative obtained. Patients in the case group who being died after got COVID 19 whereas 50 patients in the control group participated who were survive after got infected from COVID 19 patients. Result It has three categories such as a Vaccination status For the vaccination status we have seen 59 patients were not vaccinated and 41 patients was vaccinated out of 100. b Incidence There were 41 patients were vaccinated whereas 59 patients were not vaccinated. c Severity In the case of mortality we selected 50 patients who were died from the Corona and I got to know that out of 50 patients there were 12 24 patients were vaccinated whereas 38 76 patients were non vaccinated. Although for the 50 control survival group total 29 58 patients were vaccinated and 21 42 patients was not vaccinated all graph start. Conclusion we have find out that those people who got vaccinated were less infected and mortality rate very low.

In the midst of a rapidly spreading global pandemic, real-world evidence can offer invaluable insight into the most promising treatments, risk factors, and not only predict but suggest how to improve outcomes. Despite overwhelming news coverage, significant knowledge gaps regarding COVID-19 persist. The current uncertainties regarding incidence and the case fatality rate can only be addressed by widespread testing. But the paucity of testing, and diversity of approaches implemented in different countries, particularly among the general asymptomatic public, perpetuates a lack of understanding about spread and infectivity. The essential indicators that would describe the pandemic more accurately can be obtained using real-world data (RWD). To that purpose, we designed a data collection tool to collect data from hospitals that treat COVID-19 patients. The captured data will enhance our understanding of the COVID-19 pandemic, identify risk factors relevant for triage, relate to other similar seasonal infections and gain insight into the safety and efficacy of experimental and off-label therapies. Knowledge derived from a focused data collection effort will enable clinicians to adjust rapidly clinical protocols and discontinue interventions that turn out to be ineffective or harmful. By deploying our elegantly designed survey to capture routine clinical indicators, we avoid placing an additional burden on practitioners. Systematically generating real-world evidence can decrease the time to insight compared to randomized clinical trials, improving the odds for patients in rapidly changing conditions.

The coronavirus SARS-CoV-2 (COVID-19) outbreak is having a profound impact on the management of patients with cancer.
In this review, we comprehensively investigate the various aspects of cancer care during the pandemic, taking advantage of
data generated in Asia and Europe at the frontline of the COVID-19 pandemic spread. Cancer wards have been subjected to
several modifications to protect patients and healthcare professionals from COVID-19 infection, while attempting to maintain cancer diagnosis, therapy, and research. In this setting, the management of COVID-19 infected patients with cancer is
particularly challenging. We also discuss the direct and potential remote impacts of the global pandemic on the mortality of
patients with cancer. As such, the indirect impact of the pandemic on the global economy and the potential consequences
in terms of cancer mortality are discussed. As the infection is spreading worldwide, we are obtaining more knowledge on
the COVID-19 pandemic consequences that are currently impacting and may continue to further challenge cancer care in
several countries. Raymond et al-2020-targeted_oncology.

New Directions in Targeted Therapeutic Approaches for Older Adults With Mantl...i3 Health
i3 Health is pleased to make the speaker slides from this activity available for use as a non-accredited self-study or teaching resource.
This slide deck presented by Dr. Kami Maddocks, Professor-Clinical in the Division of Hematology and
Associate Division Director for Ambulatory Operations
The Ohio State University Comprehensive Cancer Center, will provide insight into new directions in targeted therapeutic approaches for older adults with mantle cell lymphoma.
STATEMENT OF NEED
Mantle cell lymphoma (MCL) is a rare, aggressive B-cell non-Hodgkin lymphoma (NHL) accounting for 5% to 7% of all lymphomas. Its prognosis ranges from indolent disease that does not require treatment for years to very aggressive disease, which is associated with poor survival (Silkenstedt et al, 2021). Typically, MCL is diagnosed at advanced stage and in older patients who cannot tolerate intensive therapy (NCCN, 2022). Although recent advances have slightly increased remission rates, recurrence and relapse remain very common, leading to a median overall survival between 3 and 6 years (LLS, 2021). Though there are several effective options, progress is still needed towards establishing an accepted frontline approach for MCL (Castellino et al, 2022). Treatment selection and management of MCL are complicated by the heterogeneity of prognosis, advanced age and comorbidities of patients, and lack of an established standard approach for treatment, making it vital that clinicians be familiar with the latest research and advances in this area. In this activity chaired by Michael Wang, MD, Professor in the Department of Lymphoma & Myeloma at MD Anderson Cancer Center, expert faculty will discuss prognostic factors informing treatment, the promising results of recent trials in new therapeutic approaches, and the implications of treatment resistance in therapeutic selection for MCL.
Target Audience
Hematology/oncology fellows, attending faculty, and other health care professionals involved in the treatment of patients with mantle cell lymphoma (MCL).
Learning Objectives
1.) Identify clinical and biological prognostic factors that can guide treatment decision making for older adults with MCL
2.) Evaluate emerging data on targeted therapeutic approaches for treatment-naive and relapsed/refractory MCL and their applicability to older adults
3.) Assess mechanisms of resistance to targeted therapies for MCL and their implications for treatment selection
Ethanol (CH3CH2OH), or beverage alcohol, is a two-carbon alcohol
that is rapidly distributed in the body and brain. Ethanol alters many
neurochemical systems and has rewarding and addictive properties. It
is the oldest recreational drug and likely contributes to more morbidity,
mortality, and public health costs than all illicit drugs combined. The
5th edition of the Diagnostic and Statistical Manual of Mental Disorders
(DSM-5) integrates alcohol abuse and alcohol dependence into a single
disorder called alcohol use disorder (AUD), with mild, moderate,
and severe subclassifications (American Psychiatric Association, 2013).
In the DSM-5, all types of substance abuse and dependence have been
combined into a single substance use disorder (SUD) on a continuum
from mild to severe. A diagnosis of AUD requires that at least two of
the 11 DSM-5 behaviors be present within a 12-month period (mild
AUD: 2–3 criteria; moderate AUD: 4–5 criteria; severe AUD: 6–11 criteria).
The four main behavioral effects of AUD are impaired control over
drinking, negative social consequences, risky use, and altered physiological
effects (tolerance, withdrawal). This chapter presents an overview
of the prevalence and harmful consequences of AUD in the U.S.,
the systemic nature of the disease, neurocircuitry and stages of AUD,
comorbidities, fetal alcohol spectrum disorders, genetic risk factors, and
pharmacotherapies for AUD.
The prostate is an exocrine gland of the male mammalian reproductive system
It is a walnut-sized gland that forms part of the male reproductive system and is located in front of the rectum and just below the urinary bladder

Title: Sense of Smell
Presenter: Dr. Faiza, Assistant Professor of Physiology
Qualifications:
MBBS (Best Graduate, AIMC Lahore)
FCPS Physiology
ICMT, CHPE, DHPE (STMU)
MPH (GC University, Faisalabad)
MBA (Virtual University of Pakistan)
Learning Objectives:
Describe the primary categories of smells and the concept of odor blindness.
Explain the structure and location of the olfactory membrane and mucosa, including the types and roles of cells involved in olfaction.
Describe the pathway and mechanisms of olfactory signal transmission from the olfactory receptors to the brain.
Illustrate the biochemical cascade triggered by odorant binding to olfactory receptors, including the role of G-proteins and second messengers in generating an action potential.
Identify different types of olfactory disorders such as anosmia, hyposmia, hyperosmia, and dysosmia, including their potential causes.
Key Topics:
Olfactory Genes:
3% of the human genome accounts for olfactory genes.
400 genes for odorant receptors.
Olfactory Membrane:
Located in the superior part of the nasal cavity.
Medially: Folds downward along the superior septum.
Laterally: Folds over the superior turbinate and upper surface of the middle turbinate.
Total surface area: 5-10 square centimeters.
Olfactory Mucosa:
Olfactory Cells: Bipolar nerve cells derived from the CNS (100 million), with 4-25 olfactory cilia per cell.
Sustentacular Cells: Produce mucus and maintain ionic and molecular environment.
Basal Cells: Replace worn-out olfactory cells with an average lifespan of 1-2 months.
Bowman’s Gland: Secretes mucus.
Stimulation of Olfactory Cells:
Odorant dissolves in mucus and attaches to receptors on olfactory cilia.
Involves a cascade effect through G-proteins and second messengers, leading to depolarization and action potential generation in the olfactory nerve.
Quality of a Good Odorant:
Small (3-20 Carbon atoms), volatile, water-soluble, and lipid-soluble.
Facilitated by odorant-binding proteins in mucus.
Membrane Potential and Action Potential:
Resting membrane potential: -55mV.
Action potential frequency in the olfactory nerve increases with odorant strength.
Adaptation Towards the Sense of Smell:
Rapid adaptation within the first second, with further slow adaptation.
Psychological adaptation greater than receptor adaptation, involving feedback inhibition from the central nervous system.
Primary Sensations of Smell:
Camphoraceous, Musky, Floral, Pepperminty, Ethereal, Pungent, Putrid.
Odor Detection Threshold:
Examples: Hydrogen sulfide (0.0005 ppm), Methyl-mercaptan (0.002 ppm).
Some toxic substances are odorless at lethal concentrations.
Characteristics of Smell:
Odor blindness for single substances due to lack of appropriate receptor protein.
Behavioral and emotional influences of smell.
Transmission of Olfactory Signals:
From olfactory cells to glomeruli in the olfactory bulb, involving lateral inhibition.
Primitive, less old, and new olfactory systems with different path

Dear Editor,
Risk factors for infectious disease severity are determined by the pathogen, host and
environment[1]. Covid-19 disease, caused by SARS-CoV-2 infection includes a spectrum of illness;
from asymptomatic infection [2] to severe pneumonia characterized by acute respiratory injury in
about 20% of patients presenting to medical care[3]. The risk factors associated with disease
severity, included increased age, diabetes, immune suppression and organ failure[3]. Recognition of
risk factors for morbidity and mortality is important to determine prevention strategies as well as to
target high-risk populations for potential therapeutics.
We performed a retrospective analysis of BMI stratified by age in Covid-19-positive
symptomatic patients who presented to a large academic hospital system in New York City. Patients
presented to the ED with signs of respiratory distress were admitted to the hospital. Critical care
was defined based on intensive care accommodation status or invasive ventilator documentation in
our electronic health record. Patients who were PCR-positive for Covid-19 during March 4, 2020-
April 4, 2020 were extracted from our electronic health record system and analyzed with a chi-
square Wald test using SAS v9.4 (SAS Institute, Care NC).
Of the 3,615 individuals who tested positive for Covid-19, 775 (21%) had a body mass index
(BMI) 30-34, and 595 (16% of the total cohort) had a BMI >35. There were 1,853 (51%) patients
discharged from the ED, 1,331 (37%) were admitted to the hospital in acute care and 431 (12%) were
either directly admitted or transferred to the ICU during admission. During analysis we found
significant difference in admission and ICU care only in patients <60 years of age with varying BMIs
(Table 1)
Patients aged <60 years with a BMI between 30-34 were 2.0 (95% 1.6-2.6, p<0.0001) and 1.8
(95% CI 1.2-2.7, p=0.006) times more likely to be admitted to acute and critical care, respectively,
compared to individuals with a BMI <30 (Table 1). Likewise, patients with a BMI >35 and aged <60

years were 2.2 (95% CI 1.7-2.9, p<.0001) and 3.6 (95% CI 2.5-5.3, p=<.0001) times more likely to be
admitted to acute and critical care compared to patients in the same age category who had BMI <30.
Though patients aged <60 years are generally considered a lower risk group of Covid-19
disease severity, based on data from our institution, obesity appears to be a previously unrecognized
risk factor for hospital admission and need for critical care. This has important and practical
implications, where nearly 40% of adults in the US are obese with a BMI >30 [4]. The BMI range of
individuals in this study appears representative of the nation, as 36% of the patients have a BMI >30.
There is geographic variation in reported mortality, as South Korea, China and Italy report case
fatality rates of 0.8, 2.3 and 7.2, respectively [5] and regional risk factors such as prevalence of
smoking, pollution or aging population has been cited. Unfortunately, obesity in people <60 years is
a newly identified epidemiologic risk factor which may contribute to increased morbidity rates
experienced in the US.
