Ethical assessment of privacy breaches in epidemiological investigations and information disclosure in the internet age: safeguarding identity information for infectious patients

While the Internet has brought convenience and speed to human life, it has also led to frequent privacy violations. In the context of epidemiological investigations and information disclosure regarding confirmed Covid-19 patients, many individuals have utilized the Internet as a means to disseminate information and engage in cyber manhunts, resulting in breaches of privacy for those involved. This phenomenon is particularly prevalent within the realm of the Internet, where the boundaries of privacy invasion become blurred. Various types of privacy infringements, both active and passive negligence, are evident on social networking platforms. The juxtaposition of the virtual world of the Internet with real-life scenarios presents novel challenges in the realm of privacy violations. The Internet era, coupled with the widespread use and integration of big data, has diminished the absolute right to privacy on the Internet. This paper examines the challenge of safeguarding the identity information of infectious patients through the lens of two theoretical frameworks -Kantianism and Utilitarianism- in an effort to address this ethical dilemma.

Aunque Internet ha aportado comodidad y rapidez a la vida humana, también ha dado lugar a frecuentes violaciones de la intimidad. En el contexto de las investigaciones epidemiológicas y la divulgación de información relativa a pacientes confirmados de covid-19, muchas personas han utilizado Internet como medio para difundir información y participar en cibercacerías, lo que ha dado lugar a violaciones en la intimidad de los implicados. Este fenómeno prevalece en el ámbito de Internet, donde los límites de la invasión de la intimidad se vuelven vagos. En las redes sociales, se manifiestan diversos tipos de violaciones de la intimidad, tanto por negligencia activa como pasiva. La yuxtaposición entre el mundo virtual de Internet con escenarios de la vida real plantea nuevos retos en el ámbito de las violaciones de la intimidad. La era de Internet, junto con el uso generalizado y la integración del bigdata, han mermado el derecho absoluto a la privacidad. Este artículo examina el reto de salvaguardar la información sobre la identidad de los pacientes infecciosos a través de la lente de dos marcos teóricos -el kantianismo y el utilitarismo- en un esfuerzo por abordar este dilema ético.

Enquanto a Internet trouxe conveniência e velocidade à vida humana, ela também levou a frequentes violações da privacidade. No contexto de investigações epidemiológicas e divulgação de informações em relação a pacientes confirmados de Covid-19, muitos indivíduos utilizaram a Internet como um meio para disseminar informação e participar de uma caçada cibernética, resultando em violações da privacidade para aqueles envolvidos. Esse fenômeno é particularmente prevalente no âmbito da Internet, onde os limites de invasão da privacidade se tornaram borrados. Vários tipos de infrações da privacidade, tanto negligências ativa como passiva, são evidentes em plataformas de redes sociais. A justaposição do mundo virtual da Internet com cenários da vida real apresenta novos desafios no âmbito das violações da privacidade. A era da Internet, juntamente com o amplo uso e integração de megadados (big data), diminuiu o direito absoluto à privacidade na Internet. Esse artigo examina o desafio de proteger a informação de identidade de pacientes infectantes através das lentes de dois enquadres teóricos -Kantianismo e Utilitarismo- em um esforço para abordar esse dilema ético.

Duración de la diarrea aguda infecciosa con el uso de leche deslactosada vs leche con lactosa en la población pediátrica: Revisión sistemática / Duration of acute infectious diarrhea with the use of lactose-free milk vs. lactose-containing milk in the pediatric population: A systematic review

Introducción: La diarrea aguda es una entidad frecuente en pediatría, constituyendo una de las principales causas de mortalidad en países en desarrollo y en niños menores de cinco años. Si bien la alimentación representa uno de los pilares fundamentales en el tratamiento de la misma, no existe consenso entre los profesionales en cuanto a la indicación de leche deslactosada durante el curso del cuadro. Objetivos: Realizar una revisión sistemática para estudiar el impacto del consumo de leche deslactosada vs leche regular en la duración de la diarrea aguda infecciosa en niños. Materiales y métodos: Se realizó una revisión sistemática incluyendo artículos publicados desde el año 2008 al 2023, utilizando para la búsqueda las bases de datos PubMed, Lillacs, Cochrane Library y literatura gris. Se incluyeron estudios experimentales, observacionales, revisiones, guías de atención y metaanálisis, realizados en pacientes pediátricos sin patologías de base, cursando cuadro de diarrea aguda infecciosa, que compararan el uso de leche deslactosada frente a leche regular. Resultados: Se seleccionaron doce artículos. En 9 de ellos se constató una disminución en la duración de la diarrea en los pacientes que recibieron leche deslactosada con una diferencia de medias de 18 horas (en un rango entre 4 y 32.6 horas). No se reportaron diferencias estadísticamente significativas en la mortalidad entre el uso de una u otra fórmula láctea. En relación al uso de una u otra fórmula no se objetivaron variaciones en el peso estadísticamente significativas. La necesidad de hospitalización fue similar entre ambos grupos. Solo un artículo analizó la frecuencia o volumen de deposiciones sin encontrar diferencias significativas (AU)

Introduction:Acute diarrhea is frequent in pediatrics, and constitutes one of the main causes of mortality in developing countries and in children under five years of age. Although feeding is one of the fundamental pillars in the treatment of diarrhea, there is no consensus among professionals regarding the indication of lactose-free milk during the course of the symptoms. Objectives: To conduct a systematic review to study the impact of lactose-free milk vs. regular milk consumption on the duration of acute infectious diarrhea in children. Materials and methods: A systematic review was conducted including articles published between 2008 and 2023, using PubMed, Lillacs, Cochrane Library databases, and gray literature for the search. Experimental and observational studies, reviews, care guidelines and meta-analysis were included, conducted in pediatric patients without underlying diseases, with acute infectious diarrhea, comparing the use of lactose-free milk versus regular milk. Results: Twelve articles were selected. Nine of them showed a decrease in the duration of diarrhea in patients who received lactose-free milk with a mean difference of 18 hours (ranging from 4 to 32.6 hours). No statistically significant differences in mortality were reported between the use of one or the other milk formula. Regarding the use of one or the other formula, there were no statistically significant variations in weight. The need for hospital admission was similar between the two groups. Only one article analyzed stool frequency or volume with no significant differences (AU)

MPOX, o que sabemos sobre propagação e controle: uma revisão integrativa / MPOX, what we know about propagation and control: an integrative review / Viruela del mono, qué sabemos sobre la propagación y el control: una revisión integradora

Esta é uma revisão integrativa que busca compreender os fatores associados à propagação e controle de mpox, seguindo as recomendações estabelecidas pela declaração Preferred Reporting Items for Systematic Reviews and Meta-Analyses. A consulta foi feita nas bases de dados PubMed, Lilacs e Cochrane Library.

Perceptions and feelings of pregnant women undergoing outpatient follow-up for toxoplasmosis

Introduction: Toxoplasmosis persists as a neglected disease and poses a challenge to public health, especially due to the risk of vertical transmission, which can lead to countless biological complications for the newborn and to psychological and emotional repercussions for the mother. Objective: To understand the perceptions and feelings of pregnant women affected by toxoplasmosis undergoing outpatient follow-up. Materials and Methods: A qualitative and exploratory study developed with 12 women with gestational toxoplasmosis undergoing specialized outpatient follow-up in a municipality from the state of Paraná, Brazil. The data were collected through semi-structured individual interviews and subjected to content analysis, supported by descending hierarchical classification. Results: The pregnant women experienced situations ranging from diagnosis and treatment to preventing the disease in the child and family. These experiences generated fear, distress and uncertainty about the disease, which were not adequately addressed during prenatal assistance in primary care. However, the pregnant women emphasized the importance of the multiprofessional team at the secondary level in monitoring and health education. Discussion: Although the pregnant women felt confident about the treatment and its implications for the child's health, discovering the diagnosis impacted their everyday lives and those of their families, especially due to lack of reliable information about toxoplasmosis and to the absence of emotional support at the primary level. Conclusions: There was a temporary scenario of disinformation among these women, who were not properly guided and supported. However, the guidelines offered in secondary health care were essential for improving knowledge and practices in health.

Improved efficiency in the management of newborns with infectious risk factors by the sepsis risk calculator and clinical observation

Abstract Objective To evaluate the efficiency of the sepsis risk calculator and the serial clinical observation in the management of late preterm and term newborns with infectious risk factors. Method Single-center, observational, two-phase cohort study comparing the rates of neonates born ≥35 weeks' gestation, ≥2000 g birthweight, and without major congenital anomalies, who were screened and/or received antibiotics for early-onset neonatal sepsis risk at our center during two periods, before (January/2018-June/2019) and after (July/2019-December/2020) the implementation of the sepsis risk calculator. Results A total of 1796 (Period 1) and 1867 (Period 2) patients with infectious risk factors were included. During the second period, tests to rule out sepsis were reduced by 34.0 % (RR, 95 %CI): 0.66 (0.61, 0.71), blood cultures by 13.1 %: 0.87 (0.77, 0.98), hospital admissions by 13.5 %: 0.86 (0.76, 0.98) and antibiotic administration by 45.9 %: 0.54 (0.47, 0.63). Three cases of early-onset neonatal sepsis occurred in the first period and two in the second. Clinical serial evaluation would have detected all true cases. Conclusions The implementation of a sepsis risk calculator in the management of newborns ≥35 weeks GA, ≥2000 g birthweight, without major congenital anomalies, with infectious risk factors is safe and adequate to reduce laboratory tests, blood cultures, hospital admissions, and antibiotics administration. Serial clinical observation, in addition, could be instrumental to achieve or even improve this goal.

Ocular manifestation of vertical transmission of dengue: case report / Manifestação ocular de transmissão vertical de dengue: relato de caso

ABSTRACT A 7-week-old male delivered by cesarean section presented with a positive serology for dengue along with preretinal and retinal hemorrhages, vitreous opacities and cotton wool spots. The patient and his mother had positive serologies for Non Structural Protein 1 (NS1) by ELISA. Retinal and vitreous findings improved over a sixteen-week period. Spectral domain optical coherence tomography (OCT) showed preserved macular architecture. In this case report, we suggest that retinal and vitreous changes may be the ocular presenting features of vertically transmitted dengue in newborns, and that those findings may resolve with no major structural sequelae.

RESUMO Neonato de 7 semanas, do sexo masculino, nascido de parto cesárea, apresentou sorologia positiva para dengue com hemorragias retinianas e pré-retinianas, opacidades vítreas e manchas algodonosas. O paciente e sua mãe haviam apresentado sorologias positivas para Non Structural Protein 1 através de ELISA. Achados na retina e no vítreo melhoraram em um período de dezesseis semanas. O exame de tomografia de coerência óptica de domínio espectral demonstrou arquitetura macular preservada. Neste relato de caso, sugerimos que alterações na retina e no vítreo podem ser os achados oculares aparentes em neonatos com infecção vertical por dengue, e que estes podem se resolver sem maiores sequelas estruturais.

The influence of growth time on the identification of Bartonella henselae strains by MALDI-TOF mass spectrometry

ABSTRACT Bartonella spp. are bacteria responsible for neglected diseases worldwide. Bartonella henselae is the species most associated with human infections. It is associated with a large spectrum of clinical manifestations and is potentially fatal. The identification of Bartonella spp. is considered a challenge in clinical routine. These bacteria are fastidious, and the time required to isolate them varies from one to six weeks. MALDI-TOF mass spectrometry has emerged as an application for research on Bartonella spp. , and has still been little explored. We investigated whether three different B. henselae strains with different growth times—14 and 28 days—could be correctly identified by MALDI-TOF mass spectra fingerprint comparison and matching. We found that the spectra from strains with different growth times do not match each other, leading to misidentification. We suggest creating database entries with multiple spectra from strains with different growth times to increase the chances of accurate identification of Bartonella spp. by MALD-TOF MS.

Transmissão vertical do HIV na rede de saúde: reflexões bioéticas sobre gênero e cuidado a partir de um caso emblemático / Vertical transmission of HIV in the health network: bioethics reflections on gender and care based on an emblematic case

Resumo Num cenário epidêmico ainda preocupante, a prevenção da Transmissão Vertical (TV) do HIV impõe problemas complexos, devido as vulnerabilidades individual, social e moral das mulheres vivendo com o vírus, somadas às fragilidades da rede de saúde. A partir de um caso emblemático, este estudo buscou compreender os desafios bioéticos do cuidado para a prevenção da TV do HIV no âmbito do Comitê de Porto Alegre/RS. Os eixos analíticos desenvolvidos refletem sobre como a produção do cuidado se articula, por um lado, com discursos e práticas relacionais pautadas no gênero e interseccionadas por raça e classe social e, por outro, com vulnerabilidades programáticas das políticas de saúde. Vislumbrou-se um processo de extrema estigmatização, em que as poucas ofertas para as mulheres cisgênero se dirigiam à regulação reprodutiva e perpetuavam dinâmicas de violência estrutural. Discute-se caminhos para a construção de um cuidado que incorpore a perspectiva decolonial e busque produzir equidade e justiça social ao reconhecer as trajetórias das mulheres.

Abstract In a still worrying epidemic scenario, the prevention of Vertical Transmission (VT) of HIV poses complex problems, due to the individual, social, and moral vulnerabilities of women living with the virus, in addition to the weaknesses of the health network. Based on an emblematic case, this study sought to understand the bioethical challenges of HIV VT prevention in the scope of the Porto Alegre/RS Committee. The analytical categories developed reflect on how the production of care is articulated, on the one hand, with relational discourses and practices based on gender and intersected by race and social class and, on the other, with programmatic vulnerabilities of health policies. A process of extreme stigmatization was revealed, in which the few offers for cisgender women were aimed toward reproductive regulation and perpetuated dynamics of structural violence. We discuss ways of building care that incorporates a decolonial perspective and seeks to produce equity and social justice by recognizing women's trajectories.

Caracterización clínica-epidemiológica de COVID-19

Las epidemias y las pandemias son eventos de ocurrencia natural. La aparición de una nueva enfermedad infecciosa supone siempre una situación compleja, sobre todo si lo hace como una epidemia de extensión o gravedad significativa, con el objetivo de describir las características clínico-epidemiológicas en pacientes confirmados con COVID-19. Se realizó un estudio descriptivo y retrospectivo sobre las características clínico-epidemiológicas de los 161 pacientes diagnosticados con esta enfermedad, en el municipio Yara, de la provincia Granma durante el período comprendido de junio de 2020-2021. Se estudiaron las variables: edad, sexo, lugar de infección, presencia o no de síntomas y signos, antecedentes patológicos personales, área de salud y consejo popular. El 60,8% de los afectados fueron del sexo femenino con 98 pacientes y el grupo de 30-44 años de edad quedó representado por 50 pacientes (31.0%); en 150 casos, la transmisión fue mayormente autóctona (93,1%) y asintomática en 86 casos para el 53,4%. De los pacientes sintomáticos fueron las manifestaciones respiratorias, los principales síntomas con 70 casos para el 93,3%, 63 pacientes tenían antecedentes personales de hipertensión arterial (39,1%). El área de salud que más casos notificó fue "Luis Enrique de la Paz" con 106 pacientes para el 65,8% y Yara el consejo popular más afectado con 72 casos (44,7%), la mayoría de los pacientes fueron del sexo femenino, predominó la transmisión autóctona y la presentación asintomática. La epidemia en el municipio Yara se comportó similar al resto del país.

Epidemics and pandemics are naturally occurring events. The emergence of a new infectious disease is always a complex situation, especially when it occurs as an epidemic of significant spread or severity. The aim of this study was to describe the clinical-epidemiologic characteristics of patients confirmed with COVID-19. A descriptive and retrospective study was carried out on the clinical-epidemiological characteristics of 161 patients diagnosed with this disease, in the municipality of Yara, province of Granma. The following variables were studied: age, sex, site of infection, presence or not of symptoms and signs, personal pathological antecedents, health area and locality. Out of the total, 98 patients were female (60.8%), and the age group 30-44 years was represented by 50 patients (31.0%). Transmission was generally autochthonous in 150 cases (93.1%), and asymptomatic in 86 cases (53.4%). Among the symptomatic patients, respiratory manifestations were the main symptom in 70 cases (93.3%). Also, 63 patients had a personal medical history of hypertension (39.1%). Luis Enrique de la Paz was the health area that reported the most cases with 106 patients (65.8%), and Yara was the most affected locality with 72 cases (44.7%). The majority of patients were female; and autochthonous transmission and asymptomatic presentation predominated. The epidemic in Yara municipality behaved alike in the whole country.

Morphometry of the wings of Anopheles aquasalis in simulated scenarios of climate change

ABSTRACT Background: Climate change has significant implications on ecosystems. We verified the effects of climate change on the malaria vector Anopheles aquasalis using simulated climate change scenarios (SSCCs). Methods: An experimental model was designed for SSCCs, which composed of air-conditioned 25 m3 rooms. Results: The wing size was significantly different between SSCCs. A colony of Anopheles aquasalis could not be established in extreme scenarios. Conclusions: Increases in temperature and CO2 in the atmosphere may modify the global epidemiology of malaria, marking its emergence in currently malaria-free areas.

Research progress of B lymphocytes in non-infectious uveitis / 国际眼科杂志(Guoji Yanke Zazhi)

Non-infectious uveitis, an autoimmune disease that can cause severe visual impairment, can be difficult to treat. According to the prevailing hypothesis, the immune-mediated imbalance that contributes to non-infectious uveitis is primarily driven by CD4+T cells. However, recent research has shown that B cells also play a significant role in this process, participating in various ways such as antibody production, antigen presentation, and cytokine secretion in both human uveitis and experimental autoimmune uveitis models. Therapies targeting B cells have been used extensively in various autoimmune diseases. Rituximab, a B-cell inhibitor, is effective in treating noninfectious uveitis that is unresponsive to conventional corticosteroid and immunosuppressive therapy. This paper provides an overview of the involvement of B cells in non-infectious uveitis and their potential use in cellular therapies, aiming to further investigate the mechanisms and develop more effective strategies for prevention and treatment.

Establishment and application of a prospective follow-up research method for acute infectious diseases in Shanghai community residents / 上海预防医学

ObjectiveTo present the exploration and application of a prospective follow-up research method for acute infectious disease surveillance based on natural community populations， using COVID-19 infection as an example， and to provide a reference for improving the infectious disease surveillance and early warning system. MethodsA multi-stage probability proportional sampling method was employed to sample residents from all communities of 16 administrative districts in Shanghai， with households as the units. A cohort for acute infectious diseases based on natural community populations was established. The baseline survey was conducted for all cohort subjects， and COVID-19 antigen test kits were distributed. From December 21， 2022 to September 30， 2023， prospective follow-up monitoring of COVID-19 antigen and nucleic acid was carried out on the study subjects on a weekly basis. The baseline characteristics and follow-up information of the cohort subjects were described. ResultsThe cohort for acute infectious diseases included a total of 12 881 subjects， comprising 6 098 males （47.3%） and 6 783 females （52.7%）. The baseline survey revealed that 35.2% （4 540/12 881） of the subjects had a history of COVID-19 infection. During the follow-up period from December 21， 2022 to September 30， 2023， the average incidence density in the cohort was 0.61/person-year， with a higher incidence density in females （0.63/person-year） compared to males （0.59/person-year）. Individuals aged 60 and above （0.64/person-year） and those with underlying health conditions （0.67/person-year） had a higher incidence density. Healthcare workers showed a notably higher incidence density （0.84/person-year） than that in other occupational groups. As of September 30， 2023， a total of 340 subjects in the cohort experienced secondary infections， with a median interval of 170 days between the first and second infections. ConclusionThis study applies cohort study method to acute infectious disease surveillance， providing crucial data support for estimating infection rates and forecasting alerts for acute infectious diseases in the community. This method can be promoted and applied as a new approach for acute infectious disease surveillance.

Sífilis en Argentina / Syphilis in Argentina

Resumen La sífilis es una enfermedad prevenible mediante barreras de protección sexual, y curable por un sen cillo tratamiento. A pesar de esto, entre 2010 y 2019, su incidencia casi se triplicó en Argentina, alcanzando 56.1/100 000. Los más afectados son los jóvenes (15-24 años), con mayor porcentaje de mujeres, especialmente entre las embarazadas, en que aumentó de 2.3% a 5.8%, con un pico de 7.7% entre 15 y 24 años. Los casos de sífilis secundaria o terciaria, detectados por pruebas de control, están en aumento. El aumento de sífilis va unido al HIV. Por ello las prue bas rápidas de detección deben hacerse conjuntamente en el primer nivel de atención, lo que facilita el acceso al diagnóstico y al tratamiento de los casos positivos, con la orientación y control correspondientes. El tratamiento con penicilina, para la que no se ha hallado resistencia, es el componente clave del control. También se usa doxicilina (no en embarazadas), o cef triaxona. Está aumentando la resistencia del Treponema pallidum a la azitromicina, por lo que debe evitarse su empleo. En 2022 se notificaron 696 casos de sífilis congénita. La tasa de nacional es 1.3 por 1000 nacidos vivos. La mayoría de los casos notificados provienen del sector público. La sífilis materna es, en áreas de bajos recursos, la causa más común de nacidos muertos. La aplicación estricta de las normas existentes, el fortalecimiento del sistema de atención primaria, y la prevención durante el embarazo, pueden contribuir a controlar y eliminar el problema de la sífilis en Argen tina.

Abstract Syphilis is a disease preventable through sexual pro tection barriers, and curable with a simple treatment. Despite this, between 2010 and 2019, its incidence al most tripled in Argentina, reaching 56.1/100 000. The most affected are young people (15-24 years old), with a higher percentage of women, especially among pregnant women, in whom it increased from 2.3% to 5.8%, with a peak of 7.7% between 15 and 24 years old. Cases of secondary or tertiary syphilis, detected by control tests, are on the rise. The increase in syphilis is linked to HIV. For this reason, rapid detection tests must be carried out jointly at the first level of care, which facilitates access to the diagnosis and treatment of positive cases, with the cor responding guidance and control. Treatment with penicillin, for which no resistance has been found, is the key component of control. Doxycillin is also used (not in pregnant women), or ceftriaxone. The resistance of Treponema pallidum to azithromycin is increasing, so its use should be avoided. In 2022, 696 cases of congenital syphilis were re ported. The national rate is 1.3 per 1000 live births. The majority of reported cases come from the public sector. Maternal syphilis is, in low-income areas, the most com mon cause of stillbirths. Strict application of existing regulations, strength ening the primary care system, and prevention during pregnancy can contribute to controlling and eliminating the syphilis problem in Argentina.
