The readers of the International Journal
of Stroke may be interested to know that
in Mexico, information on acute care
and long-term outcome of patients
with ischaemic stroke (IS) and transient
ischaemic attack (TIA) is still unknown.
TheMexicanPREMIERregistry, amulticentre
first-step stroke surveillance system,
was designed to investigate on risk
factors, acute care, secondary prevention
strategies and long-term outcome of
patients with IS and TIA. Here, we
present information on acute care and
one-year outcome of the IS cohort.

Role of Left Ventricular Mass Index Versus Left Ventricular Relative Wall Thi...Premier Publishers
In non-cardioembolic stroke patients, the cardiac manifestations of elevated blood pressure are of particular interest. The value of LV geometry in the prediction of cardiovascular risk is controversial. Many reports detected that left ventricular hypertrophy is independently associated with risk of ischemic stroke. The primary objective of this study was to identify the frequency of different patterns of altered left ventricular geometry in patients with non cardioembolic stroke, and to assess whether a significant number of patients will miss the diagnosis of LV remodeling if the left ventricular relative wall thickness(RWT) is not evaluated or reported. 100 patients were referred within 48 hours after an acute non cardioembolic ischemic stroke for a transthoracic echocardiogram. The echocardiographic findings were analyzed. Mean age was 61.86 ± 12.59 years, 45 % men. Concentric remodeling carried the highest frequency (43%), followed by normal pattern (27%), concentric hypertrophy (22%), and eccentric hypertrophy (8%). The frequency of abnormal left ventricular RWT (61.4%) was significantly higher than that of abnormal LVMI.

Background: Rotating night shift work imposes circadian strain and is linked to the risk of several
chronic diseases.
Purpose: To examine associations between rotating night shift work and all-cause; cardiovascular
disease (CVD); and cancer mortality in a prospective cohort study of 74,862 registered U.S. nurses
from the Nurses’ Health Study.
Methods: Lifetime rotating night shift work (defined as Z3 nights/month) information was
collected in 1988. During 22 years (1988–2010) of follow-up, 14,181 deaths were documented,
including 3,062 CVD and 5,413 cancer deaths. Cox proportional hazards models estimated
multivariable-adjusted hazard ratios (HRs) and 95% CIs.
Results: All-cause and CVD mortality were significantly increased among women withZ5 years of
rotating night shift work, compared to women who never worked night shifts. Specifically, for
women with 6–14 and Z15 years of rotating night shift work, the HRs were 1.11 (95% CI¼1.06,
1.17) and 1.11 (95% CI¼1.05, 1.18) for all-cause mortality and 1.19 (95% CI¼1.07, 1.33) and 1.23
(95% CI¼1.09, 1.38) for CVD mortality. There was no significant association between rotating night
shift work and all-cancer mortality (HRZ15years¼1.08, 95% CI¼0.98, 1.19) or mortality of any
individual cancer, with the exception of lung cancer (HRZ15years¼1.25, 95% CI¼1.04, 1.51).
Conclusions: Women working rotating night shifts for Z5 years have a modest increase in allcause
and CVD mortality; those working Z15 years of rotating night shift work have a modest
increase in lung cancer mortality. These results add to prior evidence of a potentially detrimental
effect of rotating night shift work on health and longevity.

Peripartum cardiomyopathy (PPCM) is an idiopathic cardiomyopathy characterized by heart failure secondary to left ventricular systolic dysfunction, typically with an ejection fraction <45%, occurring towards the end of pregnancy or in the months following delivery for which no other cause of heart failure is found.1 Rarely, catastrophic presentations can occur with severe respiratory distress and low cardiac output necessitating mechanical ventilation and circulatory support. Data on the use of extracorporeal membrane oxygenation (ECMO) in PPCM is limited. Little is known about the safety, efficacy, or mortality. The Extracorporeal Life Support Organization (ELSO) maintains an international registry of patients treated with ECMO since 1989 and collects data from over 300 pediatric and adult centers. We sought to examine the ELSO registry for PPCM patients treated with ECMO in order to characterize demographic and clinical features, complications, overall survival to discharge, and variables associated with mortality.
46 patients met inclusion criteria. 2 patients were excluded leaving 44 patients for the analysis. Overall survival to discharge was 56.8% while 75.0% of patients were weaned off ECMO. All patients had one ECMO run except for one patient who had two. All patients were conventionally ventilated.
Cardiovascular (52.3%), renal (36.4%), hemorrhagic (34.1%), mechanical (25.0%), infectious (15.9%), metabolic (15.9%), neurologic (11.4%), and pulmonary (9.1%) complications were reported.
Pre- ECMO variables associated with decreased survival included higher ventilation rate (p=0.03**, OR 0.88 [0.79-0.98]) and support with vasopressor or inotropic agents (p<0.01, OR 0.09 [0.01-0.82]). Decreased survival was also observed in patients with ECMO cannula site bleeding (p=0.02, OR 0.14 [0.02-0.83]).
Our review is the largest to date of PPCM patients supported with ECMO. We identified factors associated with mortality including pre-ECMO ventilation rate, pre-ECMO support with vasopressors, and ECMO cannula site bleeding. We believe our data supports the use of ECMO in PPCM when clinically indicated.
Cardiovascular risk evaluation and management before renal transplantation sl...Christos Argyropoulos
Presentation focused on pre-operative evaluation of Major Adverse Cardiac Events prior to renal transplantation.

Aim: of the study was to conduct a comparative analysis of inflammatory markers in patients with coronary heart disease of stable and unstable flow. Methods: 78 patients aged 36 to 75 years were enrolled in this study (mean age 58.2±12.6 years). Laboratory and instrumental data were obtained and assessed. IL-6, TNF-α in blood plasma was carried out by the method of enzyme immunoassay on a solid-phase analyzer «Humareader Single». Statistical processing of the obtained results was carried out using vibrational statistics methods recommended for biomedical research on the IBM PC AT Pentium IV. Results: In patients with unstable angina (UA), the frequency of elevated levels of CRP, TNF-α, and leukocytes was statistically significantly higher than in the group with stable ischemic heart disease (P<0.05). The mean levels of these markers were statistically significantly higher in patients with UA compared with patients with stable form of coronary heart disease (CHD, P<0.05): CRP (4.3 ± 2.4 and 2.9 ± 2.3 mg / L, p <0.05, respectively), TNF-α (10.5 ± 2.5 and 7.7 ± 3.4 pg / ml, p <0.05) and leukocytes (9.2 ± 2.5 6.9 ± 2.3x109 / l, p <0.05). The level of interleukin-6 in patients with UA was higher in comparison with patients with stable angina (SA, 3.4 ± 1.7 and 2.9 ± 0.5 pg/ml), but the difference was statistically not significant (p> 0.05 ). There were no significant differences in the level of fibrinogen and ESR between patients with UA and SA. Conclusion: It was noted that the signs of inflammation are detected both in patients with unstable forms and in patients with stable form of CHD, but the degree of inflammation in patients with UA (level of TNF-α, CRP and leukocytes) is higher than in patients with stable ischemic heart disease.
Clinical Profile of Acute Coronary Syndrome among Young AdultsPremier Publishers
Acute Coronary Syndrome accounts for 30% of hospital admissions with cardiovascular diseases. The risk of this syndrome is increasing among the younger adults, and a deep insight into the clinical profile among these patients will help in devising a preventive strategy, in order to alleviate the morbidity and mortality due to the syndrome. A cross sectional study was done among 125 subjects admitted to our tertiary care hospital with Acute Coronary Syndrome. Their risk factors were assessed and a 12 Lead electrocardiogram and 2D Echocardiogram were taken. Cardio III panel which consists of Troponin I, CK MB, BNP by COBAS meter machine was also measured. STEMI was present in 73.6% of the patients, while unstable angina was present in 16%. About 90% of STEMI patients were males and 62% of them were hypertensives. LV Ejection Fraction <30% was found in 9% of STEMI patients. This study elucidates the need for a preventive strategy for primordial prevention of cardiovascular events among young adults. The study envisaged the male, urban preponderance towards these events.

Mortalidad asociada al diagnóstico de síndrome de Guillain-Barré en adultos i...Erwin Chiquete, MD, PhD
Mortality associated with a diagnosis of Guillain-Barré syndrome in adults of Mexican health institutions
Introduction. Guillain-Barré syndrome (GBS) is a neurological emergency representing the main cause of flaccid paralysis
around the world, affecting all age groups. Little is known about the essential epidemiology of GBS in most Latin American
countries.
Aim. To determine the mortality associated with the diagnosis of GBS in hospital discharges during 2010 in hospitals of
the Ministry of Health, Mexico.
Patients and methods. We analyzed the database of hospital discharges of institutions pertaining to the Ministry of
Health. Study cases were identified by the code G61.0 of the International Classification of Diseases, 10th revision (ICD-10).
We excluded records of patients younger than 18 years and patients without complete demographic information.
Results. During the year 2010 there were 2,634,339 discharges from hospitals of the Ministry of Health. We identified a
total of 467 hospitalizations due to GBS in adults (median age: 41 years; 62.1% male) from 121 health institutions of the
32 Republic States. The highest frequency of GBS hospitalizations occurred during summer and fall. The median hospital
stay was 8 days. The hospital mortality rate was 10.5%. The probability of death was directly associated with age, without
a particular trend regarding gender, hospital care or state.
Conclusions. In 2010 GBS hospital mortality in this part of the Mexican health system was higher than that reported in
contemporary studies. A seasonal association was observed regarding the frequency of hospitalizations for GBS.
Key words. Climate. Epidemiology. Guillain-Barré syndrome. Mortality. Mexico.

Seroepidemiology of Toxoplasma gondii infection in drivers involved in road t...Erwin Chiquete, MD, PhD
Background: The prevalence of toxoplasmosis in the general population of Guadalajara, Mexico, is around 32%.
Toxoplasmosis can cause ocular lesions and slowing of reaction reflexes. Latent toxoplasmosis has been related
with traffic accidents. We aimed to assess the prevalence of anti-Toxoplasma gondii antibodies and visual
impairments related with traffic accidents in drivers from the metropolitan Guadalajara.
Methods: We prospectively evaluated the prevalence of IgG and IgM anti-T. gondii antibodies in 159 individuals
involved in traffic accidents, and in 164 control drivers never involved in accidents. Cases of toxoplasmosis
reactivation or acute infection were detected by PCR in a subset of 71 drivers studied for the presence of T. gondii
DNA in blood samples. Ophthalmologic examinations were performed in drivers with IgG anti-T. gondii antibodies
in search of ocular toxoplasmosis.
Results: Fifty-four (34%) traffic accident drivers and 59 (36%) controls were positive to IgG anti-T. gondii antibodies
(p = 0.70). Among the 113 seropositive participants, mean anti-T. gondii IgG antibodies titers were higher in traffic
accident drivers than in controls (237.9 ± 308.5 IU/ml vs. 122.9 ± 112.7 IU/ml, respectively; p = 0.01 by Student’s t
test, p = 0.037 by Mann–Whitney U test). In multivariate analyses, anti-T. gondii IgG antibody titers were consistently
associated with an increased risk of traffic accidents, whereas age showed an inverse association. The presence of
IgM-anti-T. gondii antibodies was found in three (1.9%) subjects among traffic accident drives, and in two (1.2%)
controls. Three (4.2%) samples were positive for the presence of T. gondii DNA, all among seropositive individuals.
No signs of ocular toxoplasmosis were found in the entire cohort. Moreover, no other ocular conditions were found
to be associated with the risk of traffic accidents in a multivariate analysis.
Conclusions: Anti-T. gondii antibody titers are associated with the risk of traffic accidents. We could not determine
any association of ocular toxoplasmosis with traffic accidents. Our results warrant further analyses in order to clarify
the link between toxoplasmosis and traffic accidents.
Tiempo de llegada hospitalaria y pronóstico funcional después deun infarto ce...Erwin Chiquete, MD, PhD
Introducción: La información sobre el tiempo de llegada hospitalaria después de un infartocerebral (IC) se ha originado en países con unidades especializadas en ictus. Existe poca infor-mación en naciones emergentes. Nos propusimos identificar los factores que influyen en eltiempo de llegada hospitalaria a 1, 3 y 6 h y su relación con el pronóstico funcional después delictus.Métodos: Se analizó la información de pacientes con IC incluidos en el estudio Primer RegistroMexicano de Isquemia Cerebral (PREMIER) que tuvieran tiempo definido desde el inicio de lossíntomas hasta la llegada hospitalaria. El desenlace funcional se evaluó mediante la escalamodificada de Rankin a los 30 días, 3, 6 y 12 meses.Resultados: De 1.096 pacientes con IC, 61 (6%) llegaron en < 1 h, 250 (23%) en < 3 h y 464 (42%)en < 6 h. Favorecieron la llegada temprana en < 1 h: el antecedente familiar de cardiopatíaisquémica y ser migra˜noso; en < 3 h: edad 40-69 a˜nos, antecedente familiar de hipertensión,antecedente personal de dislipidemia y cardiopatía isquémica, así como la atención en hospitalprivado; en < 6 h: antecedente familiar de hipertensión, ser migra˜noso, ictus previo, cardiopatíaisquémica y atención en hospital privado. La llegada hospitalaria tardía se asoció a ictus lacunary alcoholismo. Solo el 2,4% recibió trombólisis. Independientemente de la trombólisis, la llegadaen < 3 h se asoció a menor mortalidad a los 3 y 6 meses, además de menos complicacionesintrahospitalarias.

Introducción. El síncope mediado neuralmente, también conocido como síncope vasovagal, se define como la pérdida
súbita y transitoria del estado de alerta como consecuencia de un descenso brusco y profundo de la presión arterial.
Objetivo. Conocer las diferencias de los parámetros hemodinámicos que median el barorreflejo durante el ortostatismo
activo en pacientes con diagnóstico clínico de síncope vasovagal y sujetos sanos.
Sujetos y métodos. Estudio transversal, observacional y comparativo. Se incluyeron 20 pacientes con diagnóstico de síncope
neuralmente mediado y 30 controles, a los que se les practicó la prueba de ortostatismo activo y se les registró por
finometría la presión arterial sistólica (PAS) y la frecuencia cardíaca (intervalo entre latidos) de manera continua (latido a
latido) y no invasiva.
Resultados. Los pacientes con síncope presentaron una PAS basal con una media significativamente mayor que la de los
sanos. Las magnitudes medidas desde la PAS basal demostraron una diferencia significativa, que era de menor valor en el
grupo de los controles. No se demostraron diferencias entre grupos en la caída de la PAS desde el primer pico, recuperación
de la PAS desde la sima o en las latencias medidas en la frecuencia cardíaca.
Conclusiones. La PAS basal y la caída de la PAS medida desde la basal en posición supina fue mayor en los pacientes con
síncope mediado neuralmente que en los sujetos sanos. La magnitud de la elevación de la frecuencia cardíaca tuvo una
tendencia a ser mayor en el grupo de pacientes en comparación con el grupo control. Esto sugiere una hiperactividad
simpática en los pacientes con síncope

El delírium en pacientes que reciben cuidados paliativos es frecuente y constituyeun importante reto de diagnóstico y tratamiento. Nuestro objetivo fue realizar en 2 fases unanálisis bibliométrico de la evidencia científica reciente (2007 a 2012) sobre diagnóstico y tra-tamiento del delírium en adultos en cuidados paliativos. En la fase 1 (estudios descriptivos yrevisiones narrativas) se identificaron 133 artículos relevantes: 73 trataron el tema del delíriumde forma secundaria y en 60 artículos como tema principal. Sin embargo, solo se identificaron4 estudios observacionales prospectivos en los que el delírium fue central. De 135 artículos iden-tificados en la fase 2 (ensayos clínicos o estudios descriptivos sobre tratamiento del delírium enpacientes paliativos), solo 3 fueron sobre prevención o tratamiento: 2 estudios retrospectivosy un ensayo clínico sobre prevención multicomponente en pacientes con cáncer. Gran parte dela literatura reciente corresponde a revisiones que hablan de estudios realizados hace másde una década en pacientes diferentes a los que reciben cuidados paliativos. En conclusión, laevidencia científica reciente sobre el delírium en cuidados paliativos es escasa y subóptima.Urgen estudios prospectivos que se enfoquen específicamente en esta población altamentevulnerable.

Background: The waist-to-height ratio (WHtR) may be a better
adiposity measure than the body mass index (BMI). We
evaluated the prognostic performance of WHtR in patients
with acute ischemic stroke (AIS). Methods: First, we compared
WHtR and BMI as adiposity measures in 712 healthy
adults by tetrapolar bioimpedance analysis. Thereafter,
baseline WHtR was analyzed as predictor of 12-month allcause
mortality in 821 Mexican mestizo adults with first-ever
AIS by a Cox proportional hazards model adjusted for baseline
predictors. Results: In healthy individuals, WHtR correlated
higher than BMI with total fat mass and showed a higher
accuracy in identifying a high percentage of body fat (p <
0.01). In AIS patients a U-shaped relationship was observed
between baseline WHtR and mortality (fatality rate 29.1%).
On multivariate analysis, baseline WHtR ≤ 0.300 or >0.800 independently

A 45-year-old garbage collector was referred to our department
with a history of tonic-clonic seizures and risky
sexual behavior (anilingus). A neurological examination was
normal. Contrast-enhanced cranial CT showed calcified lesions
and viable parasites compatible with a diagnosis of
massive non-encephalitic neurocysticercosis. Oral metallic
implants impeded performing brain MRI. Hepatitis and HIV
serologies were negative. The patient was discharged with
steroids and an anticonvulsant. Delayed cysticidal therapy
was planned; however, albendazole therapy was immediately
initiated in another hospital, which led to brain edema, uncontrolled
seizures, rostrocaudal deterioration and death.
Cestoda infections are rare in developed countries (1). In
contrast, neurocysticercosis is a leading cause of adult-onset
epilepsy in Latin America. Massive infections are classified
as encephalitic or non-encephalitic (2). In patients with the
encephalitic presentation, cysticidal drugs can cause extensive
parasite lysis and aggravate brain inflammation (2). In
patients with non-encephalitic massive neurocysticercosis,
cysticidal therapy is usually considered; (2) however, rapid
initiation of antiparasitic medications can launch an encephalitic
process.

Limited data exist on the costs of care of
patients with multiple sclerosis (MS) in low- to middleincome
nations. The purpose of this study was to describe
the economic burden associated with care of Mexican
patients with relapsing-remitting MS in a representative
sample of the largest institution of the Mexican public
healthcare system. We analysed individual data of 492
patients (67 % women) with relapsing-remitting MS registered
from January 2009 to February 2011 at the Mexican
Social Security Institute. Direct costs were measured about
the use of diagnostic tests, disease-modifying therapies
(DMTs), symptoms control, medical consultations,
relapses, intensive care and rehabilitation. Four groups
were defined according to DMT alternatives: (1) interferon
beta (IFNb)-1a, 6 million units (MU); (2) IFNb-1a, 12MU;
(3) IFNb-1b, 8MU; and (4) glatiramer acetate. All patients
received DMTs for at least 1 year. The most frequently
used DMT was glatiramer acetate (45.5 %), followed by
IFNb-1a 12MU (22.6 %), IFNb-1b 8MU (20.7 %), and
IFNb-1a 6MU (11.2 %). The mean cost of a specialised
medical consultation was €74.90 (US $107.00). A single
relapse had a mean total cost of €2,505.97 (US $3,579.96).
No differences were found in annualised relapse rates and
costs of relapses according to DMT. However, a significant
difference was observed in total annual costs according to
treatment groups (glatiramer acetate being the most
expensive), mainly due to differences in unitary costs of
alternatives. From the public institutional perspective,
when equipotent DMTs are used in patients with comparable
characteristics, the costs of DMTs largely determine
the total expenses associated with care of patients with
relapsing-remitting MS in a middle-income country.
Blood pressure at hospital admission and outcome after primary intracerebral ...Erwin Chiquete, MD, PhD
Introduction: The importance of the admission blood pressure (BP) for intracerebral
hemorrhage (ICH) outcome is not completely clear. Our objective was to
analyze the clinical impact of BP at hospital arrival in patients with primary ICH.
Material and methods: We studied 316 patients (50% women, mean age:
64 years, 75% with hypertension history) with acute primary ICH. The first BP reading
at admission was evaluated for its association with neuroimaging findings
and outcome. A Cox proportional hazards model and Kaplan-Meier analyses
were constructed to evaluate factors associated with in-hospital mortality.
Results: Intraventricular irruption occurred in 52% of cases. A high frequency
of third ventricle extension was observed in patients with BP readings in the
upper quartiles of the distribution (systolic, diastolic, or mean arterial pressure).
Blood pressure readings did not correlate with hematoma volumes. In-hospital
case fatality rate was 46% (63% among those with ventricular irruption). Systolic
BP (SBP) > 190 mm Hg was independently associated with in-hospital mortality
in supratentorial (n = 285) ICH (hazard ratio: 1.19, 95% confidence interval:
1.02-1.38, for the highest vs. the lowest quartile) even after adjustment for
known strong predictors (age, ICH volume, Glasgow coma scale and ventricular
extension). Blood pressure was not significantly associated with ventricular
extension or outcome in patients with infratentorial ICH.
Conclusions: A high BP on admission is associated with an increased risk of
intraventricular extension and early mortality in patients with supratentorial
ICH. However, a significant proportion of patients with high BP readings without
ventricular irruption still have an increased risk of death.
Serum Uric Acid and Outcome after Acute Ischemic Stroke: PREMIER StudyErwin Chiquete, MD, PhD
Background: Current evidence shows that uric acid is a potent
antioxidant whose serum concentration increases rapidly
after acute ischemic stroke (AIS). Nevertheless, the relationship
between serum uric acid (SUA) levels and AIS
outcome remains debatable. We aimed to describe the
prognostic significance of SUA in AIS. Methods: We studied
463 patients (52% men, mean age 68 years, 13% with glomerular
filtration rate <60 />2) at 30 days, or with
any outcome measure at 3, 6 or 12 months poststroke. After
adjustment for age, gender, stroke type and severity (NIHSS
<9),><24 h. Conclusions: A low SUA
concentration is modestly associated with a very good
short-term outcome. Our findings support the hypothesis
that SUA is more a marker of the magnitude of the cerebral
infarction than an independent predictor of stroke outcome.

Atherothrombotic Disease, Traditional Risk Factors, and 4-Year Mortality in a...Erwin Chiquete, MD, PhD
Erwin Chiquete, MD, PhD
Background: Atherothrombosis is becoming the leading cause of chronic morbidity in developing countries. This
epidemiological transition will represent an unbearable socioeconomic burden in the near future. We investigated
factors associated with 4-year all-cause mortality in a Latin American population at high risk.
Hypothesis: Largely modifiable risk factors as well as polyvascular disease are the main predictors of 4-year all-cause and
cardiovascular mortality in this Latin American cohort.
Methods: We analyzed 1816 Latin American stable outpatients (62.3% men, mean age 67 years) with symptomatic
atherothrombosis (87.1%) or with multiple risk factors only (12.9%), in the Reduction of Atherothrombosis for Continued
Health registry.
Results: Of patients with symptomatic atherothrombosis, 57.3% had coronary artery disease, 32% cerebrovascular disease,
and 11.7% peripheral artery disease at baseline (9.1% polyvascular). The main risk factors were hypertension (76%),
hypercholesterolemia (60%), and smoking (52.3%) in patients with established atherothrombosis; and hypertension
(89.7%), diabetes (80.8%), and hypercholesterolemia (73.9%) in those with risk factors only. Four-year all-cause mortality
steeply increased with none (6.8%), 1 (9.2%), 2 (15.5%), and 3 (29.2%) symptomatic arterial disease locations. In patients
with only 1 location, cardiovascular mortality was significantly higher with peripheral artery disease (11.3%) than with
cerebrovascular disease (6%) or coronary artery disease (5.1%). Significant baseline predictors of 4-year all-cause mortality
were congestive heart failure (hazard ratio [HR]: 3.81), body mass index<20 (HR: 2.32), hypertension (HR: 1.84), polyvascular
disease (HR: 1.69), and age ≥65 years (HR: 1.47), whereas statin use (HR: 0.49) and body mass index ≥30 (HR: 0.58) were
associated with a reduced risk.
Conclusions: Hypertension was the main modifiable risk factor for atherothrombosis and all-cause mortality in this Latin

Osmotic demyelination syndrome (ODS) is the
damage over the central nervous system caused by several
electrolytes, metabolic and toxic disorders. We aimed to
describe cases of unusual forms of ODS. In a 9-year period,
25 consecutive patients with ODS (15 men; mean age
42 years) were registered in our referral institution, among
them, four (16 %) with atypical neuroimaging findings
were abstracted for this communication. None of them
presented cardiorespiratory arrest, head trauma, seizures,
neuromyelitis optica spectrum or contact with toxic
chemicals. Case 1 was a 33-year-old alcoholic man without
hypertension or electrolyte imbalance, who presented a
classic central pontine myelinolysis (CPM) and a hemorrhage
within the pons. Case 2 was a 34-year-old alcoholic
man with hypoglycemia and hyponatremia who presented
CPM and diffuse bihemispheric extrapontine myelinolysis
(EPM) after correction of serum sodium. Case 3 was a
52-year-old woman with mild hypokalemia and hyponatremia
(inadequately corrected), who presented a peduncular
and cerebellar EPM. Case 4 was a 67-year-old
woman who had a suicidal attempt with antidepressants
and carbamazepine without impaired consciousness, who
complicated with mild hyponatremia associated with a
classical CPM and a spinal cord EPM. Case 2 died and the
rest remained with variable neurological impairments at
last follow-up visit. With modern neuroimaging, the
so-called atypical forms of ODS may not be as rare as
previously thought; however, they could have a more
adverse outcome than the classical ODS.
Spontaneous intracerebral hemorrhage in Mexico: results from a Multicenter Na...Erwin Chiquete, MD, PhD
Introduction. Scarce information exists on intracerebral hemorrhage (ICH) in Latin America, and the existent is derived
from single-center registries with non-generalizable conclusions. The aim of this study is to describe the frequency, etiology,
management and outcome of ICH in Mexico.
Patients and methods. We studied consecutive patients with ICH pertaining to the National Multicenter Registry on Cerebrovascular
Disease (RENAMEVASC), conducted in 25 centers from 14 states of Mexico. The Intracerebral Hemorrhage Grading
Scale (ICH-GS) at admission was used to assess prognosis at 30 days follow-up.
Results. Of 2,000 patients with acute cerebrovascular disease registered in RENAMEVASC, 564 (28%) had primary ICH
(53% women; median age: 63 years; interquartile range: 50-75 years). Hypertension (70%), vascular malformations (7%)
and amyloid angiopathy (4%) were the main etiologies. In 10% of cases etiology could not be determined. Main ICH
locations were basal ganglia (50%), lobar (35%) and cerebellum (5%). Irruption into the ventricular system occurred in
43%. Median score of ICH-GS was 8 points: 49% had 5-7 points, 37% had 8-10 points and 15% had 11-13 points. The 30-day
case fatality rate was 30%, and 31% presented severe disability. The 30-day survival was 92% for patients with ICH-GS 5-7
points, whereas it decreased to 27% in patients with ICH-GS 11-13 points.
Conclusions. In Mexico, ICH represents about a third of the forms of acute cerebrovascular disease, and the majority of
patients present severe disability or death at 30 days of follow-up. Hypertension is the main cause; hence, control of this
important cardiovascular risk factor should reduce the health burden of ICH.

An expandable vertebral body prosthesis with dual cage-and-plate function in a single
device (JR prosthesis) was designed to test the hypothesis that this modular system can
provide the biomechanical requirements for immediate and durable spine stabilization
after corpectomy. Cadaver assays were performed with a stainless steal device to test fixation
and adequacy to the human spine anatomy. Then, 14 patients with vertebral tumors
(eight metastatic) underwent corpectomy and vertebral body replacement with a titaniummade
JR prosthesis. All patients had neurological deficit, severe pain and spine instability
prior to surgery. Mean pain score before surgery on a visual analog scale decreased from
7.6e3.0 points after operation ( p 5 0.002). All patients achieved at least one grade of
improvement in the Frankel score ( p 5 0.003), excepting the three patients with Frankel
grade A before surgery. Two patients with renal cell carcinoma died during the following
4 days after surgery. The remaining patients attained a painless and stable spine immediately,
which was maintained for long periods (mean follow-up: 25.4 months). No significant
infections or implant failures were registered. A nonfatal case of inferior vena cava
surgical injury was observed (repaired during surgery without further complications). In
conclusion, the JR prosthesis stabilizes the spine immediately after surgery and for the
rest of the patients’ life. To our knowledge, this is the first report on the clinical experience
of any expandable vertebral body prosthesis with dual cage-and-plate function in
a single device.

Low BRCA1 gene expression is associated with
increased invasiveness and influences the response of
breast carcinoma (BC) to chemotherapeutics. However,
expression of BRCA1 and BRCA2 genes has not been
completely characterized in premenopausal BC. We analyzed
the clinical and immunohistochemical correlates of
BRCA1 and BRCA2 expression in young BC women. We
studied 62 women (mean age 38.8 years) who developed
BC before the age of 45 years. BRCA1 and BRCA2 mRNA
expression was assessed by reverse transcriptase-polymerase
chain reaction (RT-PCR) and that of HER-2 and
p53 proteins by immunohistochemistry. Body mass index
(BMI) C27 (52%) and a declared family history of BC
(26%) were the main risk factors. Ductal infiltrative adenocarcinoma
was found in 86% of the cases (tumor size
[5 cm in 48%). Disease stages I–IV occurred in 2, 40, 55,
and 3%, respectively (73% implicating lymph nodes).
Women aged B35 years (24%) had more family history of
cervical cancer, stage III/IV disease, HER-2 positivity, and
lower BRCA1 expression than older women (P-.05).
BRCA1 and BRCA2 expression correlated in healthy, but
not in tumor tissues (TT). Neither BRCA1 nor BRCA2
expression was associated with tumor histology, differentiation,
nodal metastasis or p53 and HER-2 expression.
After multivariate analysis, only disease stage explained
BRCA1 mRNA levels in the lowest quartile. Premenopausal
BC has aggressive clinical and molecular
characteristics. Low BRCA1 mRNA expression is associated
mainly with younger ages and advanced clinical stage
of premenopausal BC. BRCA2 expression is not associated
with disease severity in young BC women.
En conclusión, la neurotoxicidad por exposición
crónica a PDCB es rara y ha sido poco descrita
en la bibliografía. Las propiedades lipofílicas de
este compuesto producen desmielinización central,
y dan lugar a leucoencefalopatía difusa,
supra e infratentorial. Las manifestaciones más
frecuentemente descritas son agudas, y son de
interés particular, en nuestro paciente, las manifestaciones
cognitivas de tipo demenciales en
un seguimiento a largo plazo. Las recomendaciones
domésticas deben dirigirse a evitar el
contacto por parte de los menores de edad con
este compuesto, así como a su eventual sustitución
por productos menos tóxicos.

Introducción. Existe poca información respecto a la hemorragia intracerebral (HIC) en América Latina, y la existente ha
sido derivada de registros hospitalarios de un solo centro con conclusiones no generalizables. El objetivo de este estudio
es describir la frecuencia, etiología, manejo y desenlace clínico de la HIC en México.
Pacientes y métodos. Se estudiaron pacientes consecutivos con HIC incluidos en el Registro Nacional Mexicano de Enfermedad
Vascular Cerebral (RENAMEVASC), conducido en 25 centros de 14 estados de la República Mexicana. Se usó la
Intracerebral Hemorrhage Grading Scale (ICH-GS) para estimar el pronóstico a 30 días.
Resultados. De 2.000 pacientes con ictus agudo en el RENAMEVASC, 564 (28%) presentaron HIC espontánea (53% mujeres;
edad media: 63 años; rango intercuartílico: 50-75 años). La hipertensión arterial (70%), las malformaciones vasculares
(7%) y la angiopatía amiloidea (4%) fueron las causas más frecuentes. No se determinó la etiología en el 10% de
los casos. Las localizaciones más frecuentes fueron ganglionar (50%), lobar (35%) y cerebelosa (5%). La irrupción hacia
el sistema ventricular ocurrió en el 43%. La mediana en la escala ICH-GS al ingreso hospitalario fue de 8 puntos: el 49%
presentó 5-7 puntos; el 37%, 8-10 puntos, y el 15%, 11-13 puntos. La tasa de mortalidad a 30 días fue del 30%, y el 31%
mostró discapacidad grave. La sobrevida a 30 días fue del 92% en pacientes con 5-7 puntos en la escala ICH-GS, mientras
que se redujo al 27% en aquellos con 11-13 puntos.
Conclusiones. En México, la HIC representa casi un tercio de las formas de enfermedad vascular cerebral aguda, y la mayoría de los pacientes que la padecen presentan discapacidad funcional grave o muerte a 30 días. La hipertensión es la principal causa, por lo que el control de este importante factor de riesgo debería reducir la carga sanitaria de la HIC.
Flu Vaccine Alert in Bangalore Karnatakaaddon Scans
As flu season approaches, health officials in Bangalore, Karnataka, are urging residents to get their flu vaccinations. The seasonal flu, while common, can lead to severe health complications, particularly for vulnerable populations such as young children, the elderly, and those with underlying health conditions.
Dr. Vidisha Kumari, a leading epidemiologist in Bangalore, emphasizes the importance of getting vaccinated. "The flu vaccine is our best defense against the influenza virus. It not only protects individuals but also helps prevent the spread of the virus in our communities," he says.
This year, the flu season is expected to coincide with a potential increase in other respiratory illnesses. The Karnataka Health Department has launched an awareness campaign highlighting the significance of flu vaccinations. They have set up multiple vaccination centers across Bangalore, making it convenient for residents to receive their shots.
To encourage widespread vaccination, the government is also collaborating with local schools, workplaces, and community centers to facilitate vaccination drives. Special attention is being given to ensuring that the vaccine is accessible to all, including marginalized communities who may have limited access to healthcare.
Residents are reminded that the flu vaccine is safe and effective. Common side effects are mild and may include soreness at the injection site, mild fever, or muscle aches. These side effects are generally short-lived and far less severe than the flu itself.
Healthcare providers are also stressing the importance of continuing COVID-19 precautions. Wearing masks, practicing good hand hygiene, and maintaining social distancing are still crucial, especially in crowded places.
Protect yourself and your loved ones by getting vaccinated. Together, we can help keep Bangalore healthy and safe this flu season. For more information on vaccination centers and schedules, residents can visit the Karnataka Health Department’s official website or follow their social media pages.
Stay informed, stay safe, and get your flu shot today!

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

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
Function is to store and secrete a clear, slightly alkaline fluid that constitutes 10-30% of the volume of the seminal fluid that along with the spermatozoa, constitutes semen
A healthy human prostate measures (4cm-vertical, by 3cm-horizontal, 2cm ant-post ).
It surrounds the urethra just below the urinary bladder. It has anterior, median, posterior and two lateral lobes
It’s work is regulated by androgens which are responsible for male sex characteristics

RESULTS: Overall life span (LS) was 2252.1±1742.5 days and cumulative 5-year survival (5YS) reached 73.2%, 10 years – 64.8%, 20 years – 42.5%. 513 LCP lived more than 5 years (LS=3124.6±1525.6 days), 148 LCP – more than 10 years (LS=5054.4±1504.1 days).199 LCP died because of LC (LS=562.7±374.5 days). 5YS of LCP after bi/lobectomies was significantly superior in comparison with LCP after pneumonectomies (78.1% vs.63.7%, P=0.00001 by log-rank test). AT significantly improved 5YS (66.3% vs. 34.8%) (P=0.00000 by log-rank test) only for LCP with N1-2. Cox modeling displayed that 5YS of LCP significantly depended on: phase transition (PT) early-invasive LC in terms of synergetics, PT N0—N12, cell ratio factors (ratio between cancer cells- CC and blood cells subpopulations), G1-3, histology, glucose, AT, blood cell circuit, prothrombin index, heparin tolerance, recalcification time (P=0.000-0.038). Neural networks, genetic algorithm selection and bootstrap simulation revealed relationships between 5YS and PT early-invasive LC (rank=1), PT N0—N12 (rank=2), thrombocytes/CC (3), erythrocytes/CC (4), eosinophils/CC (5), healthy cells/CC (6), lymphocytes/CC (7), segmented neutrophils/CC (8), stick neutrophils/CC (9), monocytes/CC (10); leucocytes/CC (11). Correct prediction of 5YS was 100% by neural networks computing (area under ROC curve=1.0; error=0.0).
CONCLUSIONS: 5YS of LCP after radical procedures significantly depended on: 1) PT early-invasive cancer; 2) PT N0--N12; 3) cell ratio factors; 4) blood cell circuit; 5) biochemical factors; 6) hemostasis system; 7) AT; 8) LC characteristics; 9) LC cell dynamics; 10) surgery type: lobectomy/pneumonectomy; 11) anthropometric data. Optimal diagnosis and treatment strategies for LC are: 1) screening and early detection of LC; 2) availability of experienced thoracic surgeons because of complexity of radical procedures; 3) aggressive en block surgery and adequate lymph node dissection for completeness; 4) precise prediction; 5) adjuvant chemoimmunoradiotherapy for LCP with unfavorable prognosis.

present information on acute care and
one-year outcome of the IS cohort.
A total of 1376 patients (52% women,
mean age 68Á5-years) were registered
from January 2005 to June 2006. Of
these cases, 1246 (91%) corresponded
to IS (mean NIHSS at admission: 12Á8
points) and 130 (9%) to TIA. Risk
factors, acute care practices, IS subtypes
and long-term management were recorded. Five visits were completed during one-year of follow-up.
Main risk factors were hypertension
(65%), obesity (51%) and diabetes
(35%). IS mechanisms were registered
as follows (see Table 1): 8% large-artery
atherosclerosis, 20% cardioembolism,
20% lacunes, 5% miscellaneous mechanisms and 41% undetermined aetiology.
Only 0Á6% patients received IV thrombolysis (23% arriving in o3 h after
stroke onset) and 1% endarterectomies
or stentings. The 30-day case fatality rate
in IS patients was 15%. One year after the
brain infarction, one-third of the patients had mRS 0–1 (functionally independent), one-third had mRS 2–5
(dependent) and another third died.
The one-year recurrence rate (1183 acute
survivors) was 11%.
