Predictors of mortality in patients with yellow fever: an observational cohort study

BACKGROUND: Yellow fever virus infection results in death in around 30% of symptomatic individuals. The aim of this study was to identify predictors of death measured at hospital admission in a cohort of patients admitted to hospital during the 2018 outbreak of yellow fever in the outskirts of São Paulo city, Brazil. METHODS: In this observational cohort study, we enrolled patients with yellow fever virus from two hospitals in São Paolo­the Hospital das Clínicas, University of São Paulo and the Infectious Diseases Institute "Emilio Ribas". Patients older than 18 years admitted to hospital with fever or myalgia, headache, arthralgia, oedema, rash, or conjunctivitis were consecutively screened for inclusion in the present study. Consenting patients were included if they had travelled to geographical areas in which yellow fever virus cases had been previously confirmed. Yellow fever infection was confirmed by real-time PCR in blood collected at admission or tissues at autopsy. We sequenced the complete genomes of yellow fever virus from infected individuals and evaluated demographic, clinical, and laboratory findings at admission and investigated whether any of these measurements correlated with patient outcome (death). FINDINGS: Between Jan 11, 2018, and May 10, 2018, 118 patients with suspected yellow fever were admitted to Hospital das Clínicas, and 113 patients with suspected yellow fever were admitted to Infectious Diseases Institute "Emilio Ribas". 95 patients with suspected yellow fever were included in the study, and 136 patients were excluded. Three (3%) of 95 patients with suspected yellow fever who were included in the study were excluded because they received a different diagnosis, and 16 patients with undetectable yellow fever virus RNA were excluded. Therefore, 76 patients with confirmed yellow fever virus infection, based on detectable yellow fever virus RNA in blood (74 patients) or yellow fever virus confirmed only at the autopsy report (two patients), were included in our analysis. 27 (36%) of 76 patients died during the 60 day period after hospital admission. We generated 14 complete yellow fever virus genomes from the first 15 viral load-detectable samples. The genomes belonged to a single monophyletic clade of the South America I genotype, sub-genotype E. Older age, male sex, higher leukocyte and neutrophil counts, higher alanine aminotransferase, aspartate transaminase (AST), bilirubin, and creatinine, prolonged prothrombin time, and higher yellow fever virus RNA plasma viral load were associated with higher mortality. In a multivariate regression model, older age, elevated neutrophil count, increased AST, and higher viral load remained independently associated with death. All 11 (100%) patients with neutrophil counts of 4000 cells per mL or greater and viral loads of 5·1 log10 copies/mL or greater died (95% CI 72­100), compared with only three (11%) of 27 (95% CI 2­29) among patients with neutrophil counts of less than 4000 cells per mL and viral loads of less than 5·1 log10 copies/mL. INTERPRETATION: We identified clinical and laboratory predictors of mortality at hospital admission that could aid in the care of patients with yellow fever virus. Identification of these prognostic markers in patients could help clinicians prioritise admission to the intensive care unit, as patients often deteriorate rapidly. Moreover, resource allocation could be improved to prioritise key laboratory examinations that might be more useful in determining whether a patient could have a better outcome. Our findings support the important role of the virus in disease pathogenesis, suggesting that an effective antiviral could alter the clinical course for patients with the most severe forms of yellow fever

The Philippine Male Aging Survey.

The aging male is fast becoming a global concern. The problem is predicted to become a major health issue that should be addressed immediately in order to prevent disability, morbidity, and, more importantly, mortality. As part of its commitment to increase awareness and create interest in the care of Filipino aging males, The Philippine Society for the Study of the Aging Male Foundation, Inc. (PhiSSAM), a multi-specialty society established in 2000, embarked on a survey among Filipino physicians to determine their knowledge, attitudes, and practices regarding male aging. Results showed that the majority of doctors (about 87%) thought that men may experience andropause. Most would diagnose patients based on symptoms alone, while only 20-30% used testosterone levels to make a diagnosis of andropause. Decreased libido and less strong erections were the symptoms very closely associated with low testosterone. Of those doctors responding, 89% agreed that andropause can affect the quality of a man's life as much as menopause can affect a female; only 38% had already prescribed/instituted treatment for andropause. Of the 62% non-prescribers, 58% said they were either very likely or fairly likely to institute treatment in the future if there were more clinical trials, more medical information, and more information on drugs. Major concerns on testosterone replacement therapy included prostate cancer, benign prostatic hypertrophy, and heart disease. The findings in this pilot survey indicate a need among the doctors in the Philippines for education about andropause and the available treatments.

[Effect of combined conjugated estrogen-medrogestone replacement therapy on lipid profiles, climacteric symptoms and the endometrium]. / Effets sur les lipides, les symptômes climatériques et l'endomètre d'une association d'estrogènes conjugués et de médrogestone dans le traitement hormonal substitutif.

OBJECTIVE: To assess the effects of continuous administration of conjugated estrogen combined with sequential administration of medrogestone on lipid profiles, climateric symptoms and endometrial tolerance. METHODS: This multicenter open study was conducted for one year to assess the effects of a hormone replacement therapy (HRT) regimen using Premarin (0.625 mg/day 28d/28) combined with medrogestone 5mg for 12 days (d17-d28 of each 28-day cycle) on lipid profiles, climateric symptoms and cycle control in 228 post menopausal women with an intact uterus. The subjects were recruited in 23 centers in 7 countries in Europe and Asia. Serum lipid/lipoprotein levels were determined at baseline and at cycles 3, 6, 13; endometrium biopsies were performed at screening then at cycle 13. Climateric symptoms and bleeding patterns were recorded by the patients from daily diaries cards collected at baseline and at visits during cycle 3, 6, 9, and 13. RESULTS: By cycle 3, the conjugated estrogen-medrogestone combination induced significant modifications of the lipid profile which were judged favorable. These modifications were maintained throughout treatment. All the baseline values were within normal limits. Mean variations compared with baseline values (expressed in mmol/l) after cycles 3, 6, and 13 were -0.46, -0.54, and -0.46 for total cholesterol (p<0.05), + 0.053, + 0.057, and + 0.078 for HDL-cholesterol (p<0.05) and -0.556, -0. 542, and -0.493 for LDL-cholesterol (p<0.001) respectively. VLDL-cholesterol levels were unchanged. Triglycerides increased significantly though moderately: + 0.12, + 0.15, and + 0.15 mmol/l at cycles 3, 6, and 13 respectively. Endometrial biopsies obtained at cycle 13 (n=195) did not reveal any endometrial hyperplasia. Withdrowal bleeding was predictable for a 6 to 7.4 day interval. The incidence of irregular bleeding varied from 7 to 33% and decreased progressively over the 13-cycle treatment. The incidence of amenorrhea increased from 14 to 52% over the 12 months studied. Finally, at each cycle, menopausal symptoms (mean number of hot flushes/day and Küpperman score) were significantly improved compared with the baseline. As expected, modifications were more pronounced after cycle 1, but improvements were maintained throughout the study. CONCLUSION: Continuous administration of Premarin in combination with sequential administration of medrogestone was found to be an effective treatment for menopausal symptoms. It was associated with favorable modifications of the lipid profile and was safe for the endometrium.

Reproductive endocrinology and infertility training in the Philippines.

PIP: This article provides insights into the reproductive endocrinology and infertility (REI) training in the Philippines offered by the University of the Philippines College of Medicine. First, the paper presents how the structured residency training program in obstetrics and gynecology started in the Philippines, including its subspecializations which include perinatal medicine, maternal medicine, and OB-Gyn ultrasonography, with special emphasis on REI. It then traces the history of the Philippine Society of Reproductive Endocrinology and Infertility (PSREI). The main objective of the Society is to improve the quality of training and practice in reproductive medicine and surgery. Under its established Guideline on Ethics of Infertility Management, PSREI has categorized the qualifications of physicians who should treat patients with infertility problems into three levels: Level I, Level II, and Level III care. The program is, however, constrained by problems such as lack of training centers, cost of instrumentation, lack of research grants, and resistance to accept minimally invasive surgery. The future of the program depends on the support from training centers abroad, increase in the number of local training centers, and availability of more affordable assisted reproductive technology.^ieng

[Neonatal seizures: the beginning and interruption of the treatment]. / Convulsiones neonatales: inicio e interrupción del tratamiento.

Opinions vary as to which 'neonatal seizures' should be treated and which should not be. There is also controversy as to when therapy of seizures should be discontinued. A poll taken among a group of eleven experts in these matters concurred in the opinion that classical neonatal seizures, those well established by clinical and EEG criteria, can be treated before confirmatory EEG support is obtained. They also agreed that those movements known as subtle seizures should await EEG or video/EEG confirmation before commencing therapy. Nine of these experts now believe that therapy for seizures should be terminated at an early time. Most will stop the therapy while the patient is still in the nursery with the exception of 3 who would treat the babies for 3 months.

The phenotype of the X-linked dystonia-parkinsonism syndrome. An assessment of 42 cases in the Philippines.

The clinical phenotype of X-linked recessive torsion dystonia was documented in 42 affected individuals from 21 families. In 7 families, there were 9 sibships (core families) with 2 or more affected individuals available for evaluation. The ages of the patients ranged from 29 to 79 years with a mean of 46.2 +/- 10.1 years; the mean age of onset of dystonia was 35.0 +/- 8.0 years with a range of 12 to 48 years; and the mean duration of illness was 11.1 +/- 7.9 years. First manifestations were noted in the lower extremities in 36%, the axial musculature in 29%, the upper extremities in 23%, and in the head in 12% of the cases. The majority of patients displayed gait abnormalities (90%), leg dystonia (79%), oromandibular dystonia (64%), neck dystonia (57%), blepharospasm (57%), and truncal dystonia (52%). The disease generalized in 90% of the cases within 1 to 11 years of onset (median duration, 5 years). Overall, the condition was disabling, but the Fahn-Marsden disability score did not correlate with age of onset, duration of illness, site of onset, rate of generalization, or presence of parkinsonism. Thirty-six percent of the cases displayed at least 1 of the following "parkinsonian symptoms": bradykinesia, tremor, rigidity, loss of postural reflexes and a shuffling gait. Parkinsonism was diagnosed as definite in 14%, probable in 2%, and possible in 19% of the cases. Given this high association of dystonia and parkinsonism, we propose to call the disorder X-linked dystonia-parkinsonism syndrome (XDP).(ABSTRACT TRUNCATED AT 250 WORDS)
