Healthcare personnel in 2016-2019 prospective cohort infrequently got vaccinated, worked while ill, and frequently used antibiotics rather than antivirals against viral influenza illnesses.

Background: Uncertainty about risk of illness and the value of influenza vaccines negatively affects vaccine uptake among persons targeted for influenza vaccination. Methods: During 2016-2019, we followed a cohort of healthcare personnel (HCP) targeted for free-of-charge influenza vaccination in five Lima hospitals to quantify risk of influenza, workplace presenteeism (coming to work despite illness), and absenteeism (taking time off from work because of illness). The HCP who developed acute respiratory illnesses (ARI) (≥1 of acute cough, runny nose, body aches, or feverishness) were tested for influenza using reverse-transcription polymerase chain reaction (rt-PCR). Findings: The cohort (2968 HCP) contributed 950,888 person-days. Only 36 (6%) of 605 HCP who participated every year were vaccinated. The HCP had 5750 ARI and 147 rt-PCR-confirmed influenza illnesses. The weighted incidence of laboratory-confirmed influenza was 10.0/100 person-years; 37% used antibiotics, and 0.7% used antivirals to treat these illnesses. The HCP with laboratory-confirmed influenza were present at work while ill for a cumulative 1187 hours. Interpretation: HCP were frequently ill and often worked rather than stayed at home while ill. Our findings suggest the need for continuing medical education about the risk of influenza and benefits of vaccination and stay-at-home-while-ill policies.

Improving natural ventilation in hospital waiting and consulting rooms to reduce nosocomial tuberculosis transmission risk in a low resource setting.

BACKGROUND: TB transmission in healthcare facilities is an important public health problem, especially in the often-overcrowded settings of HIV treatment scale-up. The problem is compounded by the emergence of drug resistant TB. Natural ventilation is a low-cost environmental control measure for TB infection control where climate permits that is suited to many different areas in healthcare facilities. There are no published data on the effect of simple structural modifications to existing hospital infrastructure to improve natural ventilation and reduce the risk of nosocomial TB transmission. The purpose of this study was to measure the effect of simple architectural modifications to existing hospital waiting and consulting rooms in a low resource setting on (a) improving natural ventilation and (b) reducing modelled TB transmission risk. METHODS: Room ventilation was measured pre- and post-modification using a carbon dioxide tracer-gas technique in four waiting rooms and two consulting rooms in two hospitals in Lima, Peru. Modifications included additional windows for cross-ventilation (n = 2 rooms); removing glass from unopenable windows (n = 2); creation of an open skylight (n = 1); re-building a waiting-room in the open air (n = 1). Changes in TB transmission risk for waiting patients, or healthcare workers in consulting rooms, were estimated using mathematical modelling. RESULTS: As a result of the infrastructure modifications, room ventilation in the four waiting rooms increased from mean 5.5 to 15; 11 to 16; 10 to 17; and 9 to 66 air-changes/hour respectively; and in the two consulting rooms from mean 3.6 to 17; and 2.7 to 12 air-changes/hour respectively. There was a median 72% reduction (inter-quartile range 51-82%) in calculated TB transmission risk for healthcare workers or waiting patients. The modifications cost

[High frequency of dyslipidemia in VIH-infected patients in aa peruvian public hospital]. / Elevada frecuencia disclipidemia en pacientes infectados por VIH en un Hospital público peruano.

The objective of the study was to determine the frequency and characteristics of dyslipidemia in patients with HIV in highly active antiretroviral therapy (HAART) in a Peruvian public hospital. A cross-sectional study was carried out in patients with complete lipid profile after receiving at least six months of HAART. Dyslipidemia was defined according to the criteria of the NCEP-ATP III. We reviewed 2 975 clinical histories, and included 538 (18.1%) in the analysis. The frequency of dyslipidemia was 74.7%. HAART regimens which include protease inhibitors (PI) (odds ratio [OR]: 1.22; confidence interval at 95% [CI 95%]: 1.11-1.33) and to be older than 40 years (OR: 1.17; CI 95%: 1.05-1.28) were associated with dyslipidemia, adjusted by viral load, CD4 lymphocyte level and gender. In conclusion, dyslipidemia was very common in our sample and was mainly associated with the use of PI. It is necessary to promote the dyslipidemia control as part of the comprehensive care of the patient with HIV.

El objetivo del estudio fue determinar la frecuencia y características de la dislipidemia en pacientes con VIH en terapia antirretroviral de gran actividad (TARGA) en un hospital público peruano. Se realizó un estudio transversal en pacientes que tuvieran un perfil lipídico completo luego de recibir al menos seis meses de TARGA. La dislipidemia se definió según los criterios NCEP-ATP III. Se revisaron 2975 historias clínicas, 538 (18.1%) fueron incluidas en el análisis. La frecuencia de dislipidemia fue 74.7%. Los esquemas de TARGA que incluían inhibidores de la proteasa (IP) (OR 1.22; IC95% 1,11-1,34) y la edad mayor de 40 años (OR 1.17; IC95% 1,06-1,29) mostraron asociación con dislipidemia, ajustado por carga viral, nivel de células CD4 y sexo. En conclusión, la dislipidemia fue muy frecuente en la muestra estudiada y estuvo asociada principalmente al uso de IP. Es necesario promover el control de la dislipidemia como parte de la atención integral del paciente con infección por VIH.

Detecting Mutations in the Mycobacterium tuberculosis Pyrazinamidase Gene pncA to Improve Infection Control and Decrease Drug Resistance Rates in Human Immunodeficiency Virus Coinfection.

Hospital infection control measures are crucial to tuberculosis (TB) control strategies within settings caring for human immunodeficiency virus (HIV)-positive patients, as these patients are at heightened risk of developing TB. Pyrazinamide (PZA) is a potent drug that effectively sterilizes persistent Mycobacterium tuberculosis bacilli. However, PZA resistance associated with mutations in the nicotinamidase/pyrazinamidase coding gene, pncA, is increasing. A total of 794 patient isolates obtained from four sites in Lima, Peru, underwent spoligotyping and drug resistance testing. In one of these sites, the HIV unit of Hospital Dos de Mayo (HDM), an isolation ward for HIV/TB coinfected patients opened during the study as an infection control intervention: circulating genotypes and drug resistance pre- and postintervention were compared. All other sites cared for HIV-negative outpatients: genotypes and drug resistance rates from these sites were compared with those from HDM. HDM patients showed high concordance between multidrug resistance, PZA resistance according to the Wayne method, the two most common genotypes (spoligotype international type [SIT] 42 of the Latino American-Mediterranean (LAM)-9 clade and SIT 53 of the T1 clade), and the two most common pncA mutations (G145A and A403C). These associations were absent among community isolates. The infection control intervention was associated with 58-92% reductions in TB caused by SIT 42 or SIT 53 genotypes (odds ratio [OR] = 0.420, P = 0.003); multidrug-resistant TB (OR = 0.349, P < 0.001); and PZA-resistant TB (OR = 0.076, P < 0.001). In conclusion, pncA mutation typing, with resistance testing and spoligotyping, was useful in identifying a nosocomial TB outbreak and demonstrating its resolution after implementation of infection control measures.

Estado nutricional en pacientes con VIH / Nutritional state in patients with HIV

El estudio se realizó en 113 pacientes con infección VIH que acuden a su consulta en el Hospital Nacional Dos de Mayo. 110 corresponden al género masculino. A todos se les tomó el peso, perímetro del brazo, pliegue celular subcutáneo tricipital y subescapular. Con las dos primeras medidas se calculó el Indice de Masa Corporal (IMC) y con el perímetro y el pliegue tricipital, el área grasa y el área muscular. Todas las medidas fueron tomadas con la metodología intenacionalmente aceptada, en el caso del pliegue se usó un calibrador Jhon Bull. Para el diagnóstico nutricional se utilizó las clasificaciones de James. Ferro-Luzzi y Waterloo y también la de la Organización Mundial de la Salud (OMS). En cuanto a la clasificación del estadío clínico de la infección se usó la de la OMS. El mayor compromiso del IMC se observa en los pacientes del estadío IV. En el género masculino, el 15.7 por ciento de los pacientes que se encuentran dentro del I a III estadío presentan Deficiencia Crónica Energética mientras que los del IV estadío llegan al 30.6 por ciento. El promedio encontrado para los diferentes indicadores antropométricos, a excepción de la talla, en ambos géneros, es menor en los pacientes del IV estadío. En cuanto se profundiza la Deficiencia Crónica Energética, el promedio de los indicadores de depósito disminuye. El comportamiento del IMC frente a los otros indicadores es similar a los que ocurre en personas sanas. En conclusión, el estado nutricional de estos pacientes se encuentra muy deteriorado llegando incluso a comprometer sus depósitos, lo que conllevan a una mayor disminución de sus defensas y por consiguiente a un muy mal pronóstico.
