High burden of sexually transmitted infections among under-resourced populations in the Dominican Republic.

Background: Sexually transmitted infections (STIs) are a major health issue, exacerbated by limited financial and infrastructural resources in developing countries. Methods: Prevalence of STIs was assessed in two urban centers of the Dominican Republic (DR) among populations at high risk for STIs: pregnant youth, men who have sex with men (MSM), trans women (TG), batey residents, female sex workers, and people living with human immunodeficiency virus (HIV). We conducted a cross-sectional survey and biological specimen collection to screen for Chlamydia trachomatis, Neisseria gonorrhea, Mycoplasma genitalium, Trichomonas vaginalis (trichomoniasis), Treponema pallidum (syphilis), HIV, hepatitis B and C, and human papillomavirus (HPV) among at-risk populations between 2015 and 2018. Ureaplasma urealyticum testing was also conducted even though it is not considered a STI. A non-probability community sample was recruited. Descriptive statistics examined the prevalence of STIs by population. Results: A total of 1991 subjects participated in the study. The median age was 26 years (range: 18-65). Most participants were female (65.3%), heterosexual (76.7%), and were not partnered (55.7%). Most of the participants reported unprotected vaginal sex in the last 6 months (54%); among MSM and TG almost half of the participants reported unprotected anal sex in the last 6 months and 17.6% reported drug use in the last 6 months. Almost half of the participants (49%) tested positive for one or more STIs. The most prevalent STI was Chlamydia trachomatis (12.8%), and human papillomavirus (11.9%). Among transgender women, 65.3% tested positive for an STI, 64.8% of female sex workers tested positive for an STI, and 53.8% of pregnant adolescents tested positive for an STI. Conclusion: There is a high prevalence of STIs among key and under resourced populations in the DR. Our findings highlight the need to conduct further research to optimize prevention and care strategies for structurally vulnerable and under resourced populations in the DR.

Barriers and facilitators related to COVID-19 vaccine acceptance and uptake among people living with HIV.

PURPOSE OF REVIEW: This review reports on the myriad barriers and facilitators related to COVID-19 vaccine hesitancy and factors contribution to uptake among people living with HIV (PLWH) globally published over the past year (2021-2022). RECENT FINDINGS: Across the literature, participants indicated concerns about the safety, efficacy and overall rapid development of the COVID-19 vaccine as a reason for delaying or not being vaccinated. Medical mistrust and perceptions about the risk of COVID-19 immune response and severity also played a role in COVID-19 vaccine hesitancy among PLWH. Almost every study examined different sociodemographic characteristics associated with COVID-19 vaccination acceptance and uptake, and although strong themes emerged around race/ethnicity, sex and educational attainment, the results were mixed across other characteristics, including age. Some studies also examined medical factors specifically related to PLWH including CD4 + cell count and adherence to antiretroviral therapy. SUMMARY: The findings highlight individual, structural and social differences in COVID-19 vaccine acceptance and uptake among PLWH, which are varied throughout the world. We call on researchers and interventionists to not just consider the role of medical mistrust and disinformation, but also how emotional, financial and political vulnerability plays into making decisions around COVID-19 vaccine uptake and overall healthcare.

Evaluation of Telehealth in Child Behavioral Health Services Delivery During the COVID-19 Pandemic.

OBJECTIVE: The authors quantified the impact of the use of telehealth services on patient-level clinical outcomes among children with complex behavioral and emotional needs in Idaho during the COVID-19 pandemic by comparing data collected in 2020 with data for the same months in 2019. METHODS: Longitudinal statewide data of Child and Adolescent Needs and Strengths (CANS) assessments were extracted from Idaho's mental and behavioral health system. Prepandemic assessments were matched to midpandemic assessments. A linear mixed-effect model was used to explore four child-level outcomes: psychosocial strengths-building rate, rate of need resolution within a life-functioning domain, rate of need resolution within a behavior-emotional domain, and rate of need resolution within a high-risk behaviors domain. RESULTS: The number of new patients admitted to Idaho's state-funded mental and behavioral health program decreased almost twofold from April-December 2019 to April-December 2020 (N=4,458 vs. 2,794). For most children with complex needs, the use of telehealth was as effective in terms of strengths building and needs resolution as in-person services; for children whose caregivers had issues with access to transportation, availability of telehealth services improved outcomes for the children. CONCLUSIONS: The COVID-19 pandemic in 2020 was associated with a dramatic drop in the number of children served by Idaho's mental health program. Telehealth may effectively bridge mental health service delivery while patients and providers work toward the resolution of transportation issues or may serve as a more acceptable permanent format of service delivery for some populations.

Primary Appendiceal Adenocarcinoma Masquerading as Acute Appendicitis: A Case Report.

Primary adenocarcinoma of the appendix is a rare neoplasm, and a large number are found incidentally during abdominal imaging and operations with other indications. This report examines a case of primary appendiceal adenocarcinoma discovered incidentally following a seemingly routine laparoscopic appendectomy in a 69-year-old male. The patient presented with atypical signs of acute appendicitis, including a history of waxing and waning right lower quadrant pain without anorexia, fever, or chills over five days. After undergoing laparoscopic appendectomy, histopathologic analysis of the appendix specimen revealed invasive adenocarcinoma. This case emphasizes the importance of maintaining a high index of suspicion for appendicitis versus appendiceal neoplasm in older adults presenting with atypical signs and symptoms.

Efectividad de las vacunas contra SARS-CoV-2 en hospitalizados con fallas vacunales en 10 hospitales de la CCINSHAE / Effectiveness of SARS-CoV-2 vaccines in hospitalized patients with vaccine failures in 10 CCINSHAE hospitals

Resumen: Objetivo: Evaluar la efectividad de las vacunas contra SARS-CoV-2 para evitar muerte e intubación en pacientes hospitalizados con Covid-19. Material y métodos: Se presentó un análisis de 3 565 hospitalizaciones por SARS-CoV-2 de personas mayores de 20 años de edad, reportadas con fines de salud pública por 10 hospitales de especialidad. Se comparó a los egresados por mejoría (2 094) con los fallecidos (1 471) en modelos mixtos de regresión logística ajustados por edad, sexo, número de comorbilidades y el hospital como variable aleatoria. Resultados: Un esquema completo de vacunación, con cinco tipos de vacunas disponibles, tuvo un efecto protector para muerte o intubación (RM: 0.67, IC95%: 0.54,0.83, 33% de protección); y para muerte (RM: 0.80, IC95%: 0.64,0.99, 20% de protección) estos datos se compararon con los que no habían sido vacunados. Todas las vacunas aplicadas mostraron un efecto protector con un RM<0.8, con intervalos de confianza variables. Conclusiones: El antecedente de vacunación reduce los riesgos de ser intubado y morir, aun en pacientes previamente vacunados y hospitalizados con Covid-19 grave.

Abstract: Objective: To evaluate the effectiveness of SARS-CoV-2 vaccines to avoid death and intubation in hospitalized patients with Covid-19. Materials and methods: We present an analysis of 3 565 hospitalizations for SARS-CoV-2 in people over 20 years of age, reported for public health purposes by 10 specialty hospitals, comparing those discharged for improvement (2 094) with those who died (1 471) in mixed models of logistic regression adjusted for age, sex, number of comorbidities and the reporting hospital as a random variable. Results: A complete vaccination schedule, with five types of vaccine available, had a protective effect for death or intubation (OR: 0.67, CI95%: 0.54,0.83, 33% protection) and for death (OR: 0.80, CI95%: 0.64,0.99, 20% protection) compared to those who had not been vaccinated. All the applied vaccines in the Mexican program showed a protective effect with an OR<0.8, with variable confidence intervals. Conclusions: Even in patients previously vaccinated and hospitalized with severe Covid-19, a history of vaccination reduces the risks of being intubated and dying.

Tarumã case study: Telemedicine and Artificial Intelligence applied for reducing Cardiovascular Diseases mortality and Health Cost Optimization / Estudo de caso de Tarumã: O uso de telemedicina e Inteligência Artificial para redução da mortalidade por doenças cardíacas e otimização dos recursos em saúde

Background: Telemedicine supported by Artificial Intelligence (AI) has been an ally in the fight against cardiovascular disease. Tarumã, a municipality located in São Paulo, has been using these kinds of techniques as part of a project to decrease mortality from chronic non-communicable diseases (NCDs). Objective: This study aimed to analyze the results obtained after one year of implementation of telemedicine and AI in cardiology in the city of Tarumã. Methods: All the data was supplied by the companies "iSalut" and "Portal Telemedicina", the Municipal Health Department, the health surveillance department and the company 4R Municipality Software Advisory Service. To verify the significance of data, an ANOVA analysis was carried out for non-parametric data. secondary data have been also related to demographic indicators and healthy care on national basis. Results: As a result, there was a decrease of 21% in premature deaths from cardiovascular diseases and of 25% in premature deaths from circulatory diseases. In addition, between January and August 2020, the number of deaths from CNCD dropped by 45% when compared to the same period in 2019. By relating the previous years, the ANOVA analysis showed a significance F(4,113)=14, 30 (p = 0.001), and the greatest difference was regarding the circulatory system diseases. Besides, the average cost per consultation decreased 60% and the reduction in the number of trips per patient represented a saving of R$5,300.00 in fuel expenses. Conclusion: It can be concluded that in addition to enhancing the patient care by health services, telemedicine reduced the revenue related to health expenses and optimized the use of resources by the municipality.

Introdução: A telemedicina apoiada por Inteligência Artificial (IA) tem sido aliada na luta contra as doenças cardiovasculares. Tarumã, município localizado em São Paulo, tem utilizado essas técnicas como parte de um projeto para  diminuir a mortalidade por doenças crônicas não transmissíveis (DCNT). Objetivos: Analisar os resultados obtidos após um ano de implementação da telemedicina e da IA na cardiologia no município de Tarumã. Métodos: Foram utilizados dados fornecidos pelas empresas "iSalut" e "Portal Telemedicina", Secretaria Municipal de Saúde, Vigilância Sanitária  e a empresa 4R Sistemas e Assessoria de município. Para verificar a significância dos dados foi realizada uma análise ANOVA para dados não paramétricos. Também foram acessados dados secundários relacionados aos índices demográficos populacionais e serviços de saúde em bases nacionais. Resultados: Houve diminuição de 21% dos óbitos prematuros por doenças cardiovasculares e 25% dos óbitos prematuros por doenças circulatórias. Além disso, entre os meses de janeiro e agosto de 2020, o número de óbitos  por DCNT caiu em 45% quando comparado com o mesmo período em 2019. A análise ANOVA, relacionando os anos anteriores demonstrou uma significância F(4,113)=14,30 (p =0,001), sendo que a maior diferença foi em relação às doenças do aparelho circulatório. Além disso, o custo médio  por consulta diminuiu 60% e a redução do número de deslocamento por pacientes representou uma economia de R$5.300,00 em gastos em combustível. Conclusões: Com isso, pode-se concluir que a telemedicina além de potencializar a prestação de cuidados ao paciente pelos serviços de saúde, diminuiu a receita relacionada aos gastos em saúde e otimizou a utilização de recursos pelo município.

Longitudinal predictors of male sexual partner risk among Black and Latina women in their late thirties: ethnic/racial identity commitment as a protective factor.

This study aimed to investigate predictors of male sexual partner risk among Latinas and Black women in their late thirties. We used multiple regression analysis to examine factors associated with male sexual partner risk among 296 women who participated in two waves of the Harlem Longitudinal Development Study (New York, 2011-2013 and 2014-2016). Women who experienced childhood sexual abuse had higher risk partners than those who did not [b = 0.16, 95% confidence interval (CI) = 0.06, 0.28]. Earlier marijuana use was a risk factor for partner risk in the late thirties (b = 0.12, 95% CI = 0.04, 0.27). Higher levels of ethnic/racial identity commitment mitigated this risk (b = - 0.15, 95% CI = - 0.26, - 0.04). Ethnic/racial identity commitment can be protective against male sexual partner risk among Latina and Black women who use marijuana. Further research should explore the protective role of different dimensions of ethnic/racial identity against sexually transmitted infections, including HIV.

More data are required to assess clinical response in patients receiving these antibiotic combinations.

Location and removal of non-palpable subdermal single-rod contraceptive implant.

OBJECTIVE: The objective of the study was to present the experience of the family planning service Hospital General de México, in locating and removing no palpable subdermal single-rod contraceptive implants. MATERIALS AND METHODS: A descriptive, prospective, and cross-sectional study was performed from January 2011 to April 2018. RESULTS: Hundred and sixty-four patients in whom the implant was not palpable were reviewed, the time between insertion and removal averaged 3.3 years (maximum 10 years and minimum 3 months). Three implants were inserted in the right arm, the rest on the left one. Forty-seven implants were found in fatty tissue (29%), 18 in fascia (11%), 94 in muscle (57%), 2 in the armpit (1.2%), and 3 were not found (1.8%). CONCLUSIONS: The no palpable implant is caused by an incorrect insertion technique. Migration should not be assumed as a cause of difficult location. Amount of non-palpable implants is not possible to determine due to a lack of records, but approximately 3% are considered non-palpable. Ultrasound has proven to be the study of choice to locate an incorrect inserted implant. In this case, the total number of implants was located, except in two patients.

OBJETIVO: Presentar la experiencia del servicio de planificación familiar del Hospital General de México Dr. Eduardo Liceaga en la localización y la extracción de implantes anticonceptivos subdérmicos no palpables. MATERIALS Y MÉTODOS: Estudio clínico descriptivo, prospectivo y transversal, realizado desde enero de 2011 hasta abril de 2018 en el servicio de planificación familiar del Hospital General de México Dr. Eduardo Liceaga. RESULTADOS: Se incluyeron 164 pacientes con implantes no palpables, de los cuales 161 se localizaron por ultrasonido. El promedio entre la inserción y el retiro fue de 3.3 años. Tres implantes fueron insertados en el brazo derecho y el resto en el izquierdo; tres no se encontraron. CONCLUSIÓN: Por su fácil acceso y simplicidad, el ultrasonido es el método de elección para localizar implantes profundos no palpables.

Pharmacy PEP Access Intervention Among Persons Who Use Drugs in New York City: iPEPcare Study-Rethinking Biomedical HIV Prevention Strategies.

Biomedical HIV prevention uptake has not taken hold among Black and Latinx populations who use street-marketed drugs. A pilot intervention providing a PEP informational video and direct pharmacy access to a PEP starter dose was conducted among this population. Four study pharmacies were selected to help facilitate syringe customer recruitment (2012-2016). Baseline, post-video, and 3-month ACASI captured demographic, risk behavior, and psychosocial factors associated with PEP willingness, and willingness to access PEP in a pharmacy. A non-experimental study design revealed baseline PEP willingness to be associated with PEP awareness, health insurance, being female, and having a high-risk partner (n = 454). Three-month PEP willingness was associated with lower HIV stigma (APR = 0.95). Using a pre-post approach, PEP knowledge (p < 0.001) and willingness (p < 0.001) increased overtime; however, only three participants requested PEP during the study. In-depth interviews (n = 15) identified lack of a deeper understanding of PEP, and contextualized perceptions of HIV risk as PEP access barriers. Pharmacy PEP access shows promise but further research on perceived risk and HIV stigma is warranted.

Melanoma vaginal. Reporte de un caso / Vaginal melanoma. A case report

Resumen: ANTECEDENTES: El melanoma vaginal es una alteración excepcional, por lo que el diagnóstico se establece en etapas avanzadas de la enfermedad. El pronóstico a corto plazo es malo y no existen factores de riesgo identificados hasta la fecha. CASO CLINICO: Paciente de 77 años, acudió a consulta por sangrado transvaginal fétido, de dos meses de evolución. Durante la colposcopia se observó una tumoración en la cara lateral izquierda de la vagina, que se extendía hasta su tercio inferior; la cara anterior estaba hiperpigmentada y friable. De acuerdo con el reporte de citología y la biopsia se estableció el diagnóstico de melanoma invasor. La concentración de marcadores tumorales fue positiva para HMB-45, Ki-67 (20%), MART-1 (Melan-1) y PS-100. La paciente fue enviada al servicio de Oncología para estadificación y tratamiento de la enfermedad. CONCLUSIONES: La identificación de una tumoración hiperpigmentada en la exploración ginecológica, además de la biopsia dirigida complementada con estudio de inmunohistoquímica, es sugerente de melanoma vaginal. Las pacientes con este tipo de lesión deben atenderse por un equipo médico multidisciplinario.

Abstract: BACKGROUND: Vaginal melanoma is an exceptional alteration, for which the diagnosis is established in advanced stages of the disease. The short-term prognosis is poor and there are no identified risk factors to date. CLINICAL CASE: 77-year-old patient, who came to the clinic for fetid transvaginal bleeding, two months old. During colposcopy, a tumor was observed on the left lateral aspect of the vagina, which extended to its lower third; the anterior face was hyperpigmented and friable. Based on the cytology report and biopsy, the diagnosis of invasive melanoma was established. The concentration of tumor markers was positive for HMB-45, Ki 67 (20%), MART-1 (Melan-1) and PS-100. The patient was sent to the Oncology service for staging and treatment of the disease. CONCLUSIONS: The identification of a hyperpigmented tumor on gynecological examination, in addition to a directed biopsy, complemented by an immunohistochemical study, is suggestive of vaginal melanoma. Patients with this type of injury should be cared for by a multidisciplinary medical team.

Asociación de la proteína C-reactiva ultrasensible con la composición de la dieta en niños escolares mexicanos / Association of high sensitivity C-reactive protein with diet composition in Mexican school children

La proteína C-reactiva ultrasensible (PCR-us) es un marcador de riesgo cardiovascular. En niños mexicanos sanos hay escasa evidencia que asocie los niveles séricos de este marcador con la dieta. El objetivo fue asociar los niveles séricos de PCR-us con la composición de la dieta en niños escolares mexicanos. El estudio fue transversal e incluyó 300 niños aparentemente sanos de 10 a12 años de edad. La cuantificación de PCR-us se realizó mediante nefelometría. La dieta se cuantificó con un cuestionario validado de frecuencia de consumo alimentos. Mediante el paquete estadístico SPSS v18, se realizaron pruebas de estadística descriptiva, correlación y modelos de regresión multivariada. El 53,7% fueron niñas y el 46,3% niños. La mediana de la PCR-us fue de 0,3 mg/L (rango: 0,3-6,8 mg/L). Se observó una correlación directa significativa entre la concentración sérica de la PCR-us con la ingesta de proteínas (rho= 0,126, p= 0,029), ácidos grasos totales (rho= 0,128, p= 0,027), ácidos grasos saturados (rho= 0,159, p= 0,006). Mediante el análisis de regresión múltiple se asoció la PCR-us con la ingesta de proteínas (β= 0,203, p=0,037) e inversamente con los granos enteros (β=-0,175, p= 0,002). Con el resto de las variables no se observó asociación significativa. La concentración sérica de la PCR-us se asoció directamente con el consumo de proteínas, ácidos grasos totales y saturados e indirectamente con el consumo de granos enteros.

The high-Sensitivity C-Reactive Protein (hs-CRP) is a cardiovascular risk marker. In healthy Mexican children, there islittle evidence that shows any relationship between serum levels of this marker with diet. The objective of this studywas to associate serum levels of hs-CRP with the diet composition in Mexican school children. The cross-sectional study included 300 seemingly healthy children of 10 to 12 years of age, 53.7% were girls and 46.3% boys.hs-CRP quantification was determined by nephelometry. The diet was quantified with a validated food frequency questionnaire. A descriptive statistical analysis, correlation and multivariate regression models were performed by using the SPSS v18 statistical software. The median of the hs-CRP was 0.3 mg / L (range: 0.3 to 6.8 mg / L). A significant direct correlation was found between serum hs-CRP with protein intake (rho=0.126, p=0.029), total fatty acids (rho = 0.128, p = 0.027) and saturated fatty acids (rho = 0.159, p = 0.006). hs-CRP was associated with the intake of protein (β = 0.203, p = 0.037) by multiple regression analysis, and inversely with whole grains (β = -0.175, p = 0,002). No significant association was found with the rest of the other variables. The serum concentration of hs-CRP was directly associated with the consumption of protein, total and saturated fatty acids and was indirectly proportional with the consumption of whole grains.

[Cervical lymphangioma in the adult. A report of 2 cases]. / Linfangioma de cuello en el adulto. Reporte de 2 casos.

BACKGROUND: Cervical lymphangiomas are uncommon benign congenital malformations usually present in children, and are rare in adults. Currently, complete resection is still the standard care. Two cases are presented of a cervical lymphangioma in an adult. The diagnosis and surgical approach is also discussed. CLINICAL CASE: Case 1. The first case is a 23 year old male with chief complaint of a tumour in the posterior triangle of the neck, which showed a substantial increase in size in the last 9 months. No associated signs or symptoms, or any trauma history was reported. CT scan of the neck showed images suggestive of a posterior cervical lymphangioma. Exploratory cervical surgery was performed, with complete resection of a cystic tumour located in the posterior triangle of the neck. Surgery was performed without complications and postoperative care was unremarkable. CASE 2: The second case is a 28 woman with a cystic tumour in submandibular space. She had history of a previous incomplete operation in another institution 2 years ago, with recurrence of the tumour. A second surgery was performed with complete resection without complications, and with a good outcome. CONCLUSIONS: Cervical lymphangioma is a very rare benign disease, surgical treatment is preferred, but sclerotherapy can be used as alternative treatment.

Osteoartritis (artrosis) de rodilla / Knee osteoarthritis (osteoarthrosis)

Evaluation of Pharmacy-Based HIV Testing in a High-Risk New York City Community.

Blacks/Hispanics face limited access to HIV testing. We examined in-pharmacy HIV testing among customers in pharmacies participating in a nonprescription syringe program in New York City. Participants were recruited in two pharmacies to complete a survey and receive an optional HIV test. Bivariate and multivariable analyses were performed to examine associations of demographics and risk behaviors with receiving in-pharmacy HIV testing. Most participants were male (55%), black (80%), had used hard drugs (88%), and 39.5% received in-pharmacy HIV testing. Being female (AOR=2.24; 95%CI 1.24-4.05), having multiple sex partners (AOR=1.20; 95% CI 1.06-1.35), having an HIV test more than 12 months ago (AOS=4.06; CI 1.85-8.91), injecting drugs in last 3 months (AOR=2.73; 95% CI 1.31-5.69) and having continuous care (AOR=0.32; 95% CI 0.17-0.58) were associated with receiving in-pharmacy HIV test. These data provide evidence of in-pharmacy HIV testing reaching persons at risk of HIV. HIV testing in pharmacies may complement existing strategies.
