<b>Background: </b> Neurocysticercosis (NCC) is the commonest helminthic CNS infection and main cause of adult-onset seizures in developing countries, also frequent industrialized countries because immigration from endemic zones. Although NCC commonly seen individuals with areas, its role as a epilepsy has been questioned on basis poor methodology published studies. <b>Objective: To determine, cysticercosis-endemic area northern Peruvian coast, frequency 1) epileptic seizures, 2) serum...
We report a 23% asymptomatic severe acute respiratory syndrome coronavirus 2 (SARS CoV-2) Omicron carriage rate in participants being enrolled into clinical trial South Africa, 15-fold higher than trials before Omicron. also found lower CD4 + T-cell counts persons with human immunodeficiency virus (HIV) strongly correlated increased odds of SARS-CoV-2 polymerase chain reaction (PCR) positive.
Background Neurocysticercosis accounts for 30%–50% of all late-onset epilepsy in endemic countries. We assessed the clustering patterns Taenia solium human cysticercosis seropositivity and seizures around tapeworm carriers seven rural communities Peru. Methodology The presence T. solium–specific antibodies was defined as one or more positive bands enzyme-linked immunoelectrotransfer blot (EITB). Neurocysticercosis-related cases were diagnosed clinically had neuroimaging EITB. Principal...
Background Acute respiratory illnesses and influenza-like (ILI) are a significant source of morbidity mortality worldwide. Despite the public health importance, little is known about etiology these acute in many regions South America. In 2006, Peruvian Ministry Health (MoH) US Naval Medical Research Center Detachment (NMRCD) initiated collaboration to characterize viral agents associated with ILI describe clinical epidemiological presentation affected population. Methodology/Principal...
Human rhinoviruses (HRVs) belong to the Picornaviridae family with high similarity human enteroviruses (HEVs). Limited data is available from Latin America regarding clinical presentation and strains of these viruses in respiratory disease. We collected nasopharyngeal swabs at clinics located eight American countries 3,375 subjects aged 25 years or younger who presented influenza-like illness. Our had a median age 3 1.2:1.0 male:female ratio. HRV was identified 16% HEV 3%. HRVs accounted for...
<i>Background:</i> Epilepsy is a serious neurological disorder and neurocysticercosis (NCC), the central nervous system infection by larvae of <i>Taenia solium</i>, main cause acquired epilepsy in developing countries. NCC becoming more frequent industrialized countries due to immigration from endemic areas. Previously reported incidences range 30 50/100,000 people 90 122/100,000 <i>Objectives:</i> To determine incidence cysticercosis area...
Background Human parainfluenza viruses ( HPIV s) are common viral causes of community‐acquired pneumonia, particularly in children. The four types have world‐wide distribution; however, limited information exists about the epidemiological profile L atin‐ A merica. Objective Provide epidemiologic and phylogenetic s that circulated atin merica between 2006 2010 to better characterize extent variability this respiratory virus region. Methods Oropharyngeal swabs, demographic data clinical...
Abstract Background In addition to demonstrated public health benefits on reducing transmission, it remains unclear how early antiretroviral therapy (ART) must be started after acquisition of human immunodeficiency virus (HIV) maximize individual benefits. Methods We conducted an open-label randomized clinical study in Lima, Peru among adult men who have sex with and transgender women acute (HIV-antibody negative/HIV-1 RNA positive) or recent (confirmed negative HIV-antibody test within 3...
While human illness associated with hantavirus infection has been documented in many countries of South America, evidence for transmission Peru limited to the isolation Rio Mamore virus from a pigmy mouse rat (Oligoryzomys microtis) Amazon city Iquitos. To address possibility exposure region, we screened febrile patients reporting health clinics Iquitos 2007 2010 serological recent infection. In addition, conducted survey hantavirus-reactive IgG among healthy participants residing and rural...
Expedited Partner Therapy (EPT) has been shown to improve treatment outcomes among heterosexual partners of individuals with curable sexually transmitted infections (STIs). Although the use EPT men who have sex (MSM) debated, due potential for missed opportunities diagnose unidentified cases HIV and syphilis infection in symptomatic partners, increases partner notification (PN) resulting from may promote testing otherwise partners. We assessed impact on self-reported PN MSM Peru gonorrheal...
The aim of this study was to analyze the rates condom use among military and police populations in Peru, focusing on differences by type partner. A Knowledge Attitudes Practices survey conducted 6,808 personnel 18 Peruvian cities between August–September 2006 September–October 2007. total 90.2% respondents were male; mean age 37.8 years 77.9% married/cohabiting. In all, 99.5% reported having had sex; 89% participants their last sexual contact with stable partner, 9.7% a nonstable 0.8% sex...
A detailed understanding of intentions and practices related to partner notification (PN) following STI diagnosis can improve control strategies. We assessed participant-level partner-level factors guiding behaviour among men who have sex with and/or transgender women (MSM-TW) in Lima, Peru, including discordances between anticipated actual notification.Men newly diagnosed gonorrhoea, chlamydia syphilis 2012 2014 reported recent partners' characteristics, PN practices, outcomes diagnosis....
A substantial body of literature has characterized how psychosocial factors, including HIV-related stigma and coping, are associated with HIV testing care utilization post-diagnosis. Less is known about if certain characteristics pre-diagnosis may also predict linkage to among individuals who receive an HIV-positive diagnosis. We examined awareness/perception dispositional coping styles predicted within three months post-diagnosis a secondary analysis 604 patients from randomized controlled...
This pilot study examines associations of perceived stigma pre-diagnosis with experienced and social support post-diagnosis qualitative data; quantifies the interplay between pre- factors on depressive symptoms among a sample newly diagnosed Peruvian men who have sex (n = 67 total). Qualitative findings highlight differences perceptions pre-disclosure actual experiences post-disclosure for most participants. Perceived was significantly related to support, B -0.35, p 0.03, marginally...

Characterization of HIV risk factors among transwomen and men who have sex with (MSM) should be assessed separately independently. However, due to several constraints, these populations continue conflated in clinical research data. There are limited datasets globally powered make such comparisons. The study aimed use one the largest surveys MSM Latin America determine differences related correlates between two populations. Secondary data analysis was completed using a cross-sectional...

In Lima, Peru, men who have sex with (MSM) and transgender women (TW) are disproportionately affected by HIV. Patterns of sexual behavior vary partner type, which has implications for HIV prevention intervention design.
