Clinical and epidemiological characteristics of prisoners infected and deceased by COVID-19, National Penitentiary Institute of Peru, 2020.

OBJECTIVES: To describe the clinical and epidemiological characteristics of inmates who were infected and died from COVID-19 in Peruvian prisons from April to October 2020. MATERIAL AND METHOD: Descriptive, cross-sectional, retrospective study with a secondary data source. All the inmates who were infected and died from COVID-19 in Peruvian prisons during the study period were considered. The information was collected through the validated data collection sheet and was analyzed with descriptive statistics applying the SPSS v26 software. RESULTS: 37,103 (42.3%) inmates were analyzed out of a prison population of 87,754. All of them reactive to the rapid test, with a mean age of 39.9 ± 12.6 years; 95.5% were male. 60.1% were IgG reactive; 36.1% were IgM/IgG reactive and 3.8% were IgM reactive. 20.1% of reactive inmates had COVID-19 symptoms at the time of testing. The most frequent symptoms were headache (55.6%), general malaise (49.7%), fever (49.0%) and cough (48.0%). Among the risk factors for COVID-19 were: age over 60 years (8.4%), high blood pressure (2.8%) and diabetes mellitus (2.4%). 445 deaths were registered. Total fatality reached 1.2% of the number of infected. The highest number of deaths was recorded in April and May (89 and 162, respectively). DISCUSSION: The study findings imply different approaches to managing epidemics in the prison context compared to the general population. The short and long term scenarios are uncertain, but the need to reorganize the prison health system, and to prioritise and modernise it are evident. The long-delayed reform of the prison system and the measures that set out to contain the spread of the COVID-19 disease in prisons are related processes in this regard.

Experiences of incarcerated mothers living with their children in a prison in Lima, Peru, 2020: a qualitative study.

OBJECTIVES: This study explores the experiences of incarcerated women living with their children in the Women Chorrillos Penitentiary, Lima, Peru, 2020. MATERIAL AND METHOD: Qualitative, exploratory study with a phenomenological design, through semi-structured interviews with inmates who lived with their minor in the prison. In total there were 13 interviews considering the theoretical saturation of categories. RESULTS: The experiences consisted of mostly negative intrapersonal experiences, related to different individual aspects and the conditions of confinement and prison treatment. Serious deficiencies perceived in the health care of inmates and children stand out, with emphasis on mistreatment and indifference on the part of the staff. Other factors involved in the construction of these experiences were identified. DISCUSSION: The results provide evidence of serious structural and organizational deficiencies that violate the fundamental rights of the population group studied. Government efforts to date are partial and insufficient. Sustainable policies and programs are urgently needed that prioritize quality health care and adequate prison treatment for these people with an emphasis on preventive promotional actions. There is a need for evidence-based interventions to reduce the harmful effects of childhood incarceration.

Interactions between Triatoma infestans and Triatoma sordida (Hemiptera: Reduviidae) in artificial ecotopes: population growth and age structure.

Interaction characteristics between Triatoma infestans Klug, 1834 and Triatoma sordida Stal, 1859 populations were studied in artificial ecotopes for 16 mo. The experimental design involved simultaneous treatments with T. infestans and T. sordida together in the same experimental unit (EU) and each separately in two control units (CU) made of adobe bricks. Chickens were used as host animals. Each unit was dismantled monthly to estimate triatomine population size and age structure, rebuilt, and repopulated with the same insects. In both units, T. infestans population growth followed a logistic model, whereas T. sordida did not show this pattern. T. infestans completed a generation in 24 wk (EU) and 32 wk (CU1), whereas T. sordida did not complete one generation during this period. We concluded that T infestans showed a better colonizing success than T. sordida. After living together for 1 yr, an interference process took place that resulted in the extinction of T. sordida.

[Contribution to knowledge of reservoirs of Trypanosoma cruzi (Chagas, 1909) in Corrientes Province, Argentina]. / Contribución al conocimiento de los reservorios del Trypanosoma cruzi (Chagas, 1909) en la Provincia de Corrientes, Argentina.

In order to identify Trypanosoma cruzi reservoirs in transmission areas, 60 mammals in Capital and San Luis del Palmar Departments, Corrientes, Argentina were studied. Primates, rodents, carnivores, marsupials and edentates were investigated, 40 of them living in captivity and 20 caught with traps in a rural area. The mammals were examined by xenodiagnosis and third or fourth instars nymphs of Triatoma infestans starved for 2 weeks were used. The feces were microscopically observed (400x) for Trypanosoma cruzi infection at 30, 60 and 90 days after feeding. Trypanosoma cruzi-like parasites were identified in 2 Saimiri sciureus and 1 Cebus apella analyzed by xenodiagnosis. It was concluded that parasitemia was low. However, the presence in a forest area of Didelphis albiventris, potential reservoir of the parasite, indicates a risk factor and deserves further epidemiological study for a true diagnosis of this endemic infection.

[Clinical cross-sectional and epidemiologic study of Chagas disease in a rural area of the Argentinian northeast]. / Estudio transversal clínico y epidemiológico de la enfermedad de Chagas en una área rural del Nordeste Argentino.

The main goal was to know the epidemiologic, clinical, electrocardiographic and radiologic characteristics among a population of seropositives and seronegatives to Trypanosoma cruzi in a rural area of the Department of San Miguel, province of Corrientes, Argentina. One hundred and thirty-two patients of different ages: 2-79 years old were researched (58 males, 74 females). In order to make a thorough assessment clinical evaluation and cardiologic testing were carried out. Signs and symptoms consistent with heart disease, blood pressure, 12-lead ECG registry and chest x-ray (PA view) were registered. In signs and symptoms, abnormal ECG patterns and radiologic abnormalities, non-significant statistic difference were observed. Although we were unable to find a significant relationship between chagasic infection and a higher prevalence for heart disease, it is important to stress the fact that 54.0% of the studied population was largely composed of very young patients whose ages were less than 20 years old, and 45.0% of those older than 41 years showed ECG abnormalities.

Esta investigación tiene por objeto analizar las características epidemiológicas, clínicas, electrocardiográficas y radiológicas de una población de seropositivos y seronegativos al Trypanosoma cruzi en una área rural del Departamento San Miguel, provincia de Corrientes, Argentina. Se seleccionaron 132 pobladores (58 hombres y 74 mujeres) de todos los grupos etareos para la realización de un examen clínico y cardiovascular. Se registraron síntomas y signos compatibles con afección cardíaca, tensión arterial, electrocardiograma de 12 derivaciones y radiografía anteroposterior de tórax. En la signo-sintomatología, anomalías electrocardiográficas y en las alteraciones radiográficas detectadas, no se observaron diferencias estadísticamente significativas entre seropositivos y seronegativos. Se concluye que si bien en la población objeto de estudio la infección chagásica no se asoció a mayor prevalencia de cardiopatía, cabe destacar que los pacientes chagásicos pertenecían a un grupo etareo muy joven con un 54,0% de ellos menores de 20 años y que el 45,0% de los pacientes mayores de 41 años tenían alteraciones electrocardiográficas.

Infestacion domestica por Triatoma infestans y prevalencia de seropositivos al Trypanosoma cruzi en un area rural del nordeste argentino / Domestic infestation by Triatoma infestans and prevalence of seropositives to Trypanosoma cruzi in a rural population of the Northeast of Argentina

An epidemiological study was carried out from April 1991 to December 1993 to obtain a general view of T. cruzi domestic transmission in rural areas of San Miguei Department, Corrientes. From 100 analyzed households, 50.0 per cent was infested by T infestans (Klug, 1834) and 1.0 per cent by T. sordida (Stal, 1859). Domiciliary colonization by T. sordida is reported for first time in Corrientes province. T. cruzi infection of T. infestans was 23.1 per cent. Indirect hemagglutination and indirect immunofluorescence antibody tests were used for detection of anti T. cruzi antibodies in 388 human sera, 23.4 per cent showed serological reactivity. An important high rate (12.9 per cent) was observed in the age group of higher transmission risk. Seropositives percentages increased with age and reached 50.0 per cent in 31-40 years old group. Domestic infestation by T. infestans, seropositive human prevalence to T. cruzi and householders precarious life conditions prove that this endemic disease is still a problem in the studied area.

[Population interactions between Triatoma infestans and Triatoma sordida]. / Interacción entre poblaciones de Triatoma infestans y Triatoma sordida.

Populations of T. infestans and T. sordida were studied between September 1988 and April 1989 with a view to discovering if any kind of interaction took place between them while they lives together in the same experimental unit and exploited the same food resource (chicken). The initial age structure for each species was: 27 N1, 7 N2, 11 N3, 3 N4, 8 N5, 4 males and 10 females. The population dynamics nutritional status, predation and gregarious behavior were estimated by means of a monthly census. The colonizing success of T. infestans was greater than that of T. sordida in view of the values obtained: fecundity (146 eggs/female), longevity (157.8 days) and mortality (39.4) compared with the values recorded for T. sordida: 118 eggs/female, 81.1 days and 54.0% respectively. The population growth of T. insfestans followed an exponential model, with a high nymphal recruitment rate, while the T. sordida population was early extinguished. In general, the average weight of T. infestans remained close to the initial values while that of T. sordida declined. Gregarious groups were formed principally in the inferior sector of wall 1 (near the host) with a higher aggregation in T. infestans. These results make it possible to propose the hypothesis of the competitive superiority of T. infestans.
