Unveiling the Intrusion: An Emergent Journey Into Tuberculous Pericarditis.

We present an interesting case of mycobacterial tuberculosis pericarditis presenting as effusive constrictive pericarditis with early cardiac tamponade in a young Mexican migrant of Haitian descent. The patient underwent a pericardial window and was treated with rifampin, isoniazid, pyrazinamide, ethambutol, and vitamin B6. After further receiving steroids, the patient was doing well and was discharged home safely.

Early Detection of Cancer and Precancerous Lesions in Persons with HIV through a Comprehensive Cancer Screening Protocol.

BACKGROUND: Non-AIDS defining malignancies present a growing challenge for persons with HIV (PWH), yet tailored interventions for timely cancer diagnosis are lacking. The Spanish IMPAC-Neo protocol was designed to compare two comprehensive cancer screening strategies integrated into routine HIV care. This study reports baseline data on the prevalence and types of precancerous lesions and early-stage cancer among participants at enrolment. Acceptability of the procedure was additionally assessed. METHODS: Cross-sectional analysis of a comprehensive screening protocol to detect precancer and cancer. The readiness of healthcare providers to implement the protocol was evaluated using a validated 4-item survey. RESULTS: Among the 1430 enrolled PWH, 1172 underwent 3181 screening tests, with positive findings in 29.4% of cases, leading to further investigation in 20.7%. Adherence to the protocol was 84%, with HIV providers expressing high acceptability (97.1%), appropriateness (91.4%), and feasibility (77.1%). A total of 145 lesions were identified in 109 participants, including 60 precancerous lesions in 35 patients (3.0%), 9 early-stage cancers in 9 patients (0.8%), and 76 low-risk lesions in 65 subjects (5.5%). Adverse events related to screening occurred in 0.8% of participants, all mild. The overall prevalence of cancer precursors or early-stage cancer was 3.8% (95% CI, 2.74%-5.01%), with highest rates observed in individuals screened for anal and colorectal cancers. CONCLUSIONS: The baseline comprehensive cancer screening protocol of the IMPAC-Neo study successfully identified a significant proportion of PWH with precancerous lesions and early-stage cancer. High adherence rates and positive feedback from providers suggest effective implementation potential in real-world healthcare settings.

Acceptability of Long-Acting Injectable Antiretroviral Treatment for HIV Management: Perspectives of Patients and Physicians in Spain.

We assessed the prevalence and factors associated with HIV-infected patients' interest in trying long-acting injectable antiretroviral treatment (LAI-ART) along with its expected benefits and concerns, and evaluated physicians' opinions about LAI-ART. This study was set within the multi-center prospective CoRIS cohort, comprising HIV-positive adults, naïve to antiretroviral treatment (ART) at study entry, recruited from 2004 onward in 48 centers in Spain. In June 2022, we conducted a 2-day cross-sectional survey among patients across 34 CoRIS centers and sent an online questionnaire to all physicians prescribing ART in 39 CoRIS centers. Of the 271 patients included, 83.3% [95% confidence interval (CI)]: 78.0 - 87.0%) expressed interest in receiving LAI-ART. This interest was higher among men (adjusted odds ratio: 2.96; 95% CI: 1.4-6.12), those aged <50 years (2.41; 1.23 - 4.73), and individuals inconvenienced by oral ART (5.03; 1.47 - 17.15), daily intake (14.65; 3.44-62.46), carrying HIV pills constantly (7.19; 2.88 - 17.96), and taking multiple medications (3.94; 1.58 - 9.85). Among the 154 physicians surveyed, 45.5% believed LAI-ART would be the preferred option for patients. Although most physicians (92.9%) thought LAI-ART could improve patients' quality of life (QoL), concerns were raised by 37.7% and 44.2% of them regarding injection site pain and visit rescheduling, respectively. Interest in LAI-ART was higher among men, those aged <50 years, and individuals finding their oral ART inconvenient. Physicians believed LAI-ART could improve QoL and overcome treatment challenges, yet concerns were raised about its potential usage difficulties. Although most patients were interested in receiving LAI-ART, only less than half of the physicians considered it their preferred option, likely owing to concerns about missed visits and injection site pain.

HLA-C*07 is associated with symptomatic HIV-1-associated neurocognitive disorders (HAND) and immune dysregulation.

BACKGROUND: HIV-1-associated neurocognitive disorders (HAND) in stable patients undergoing antiretroviral therapy (ART) may result from ongoing immune dysregulation and chronic inflammation. A contributing factor may result from the unstable HLA class I allele, HLA-C*07. OBJECTIVE: To assess the genetic profile of killer-cell immunoglobulin-like receptors (KIR), human leukocyte antigens (HLA), and immune activation or senescence markers and their association with HAND in stable HIV-1 patients receiving ART. METHODS: An observational cross-sectional study was carried out with 96 patients with asymptomatic or symptomatic HAND. HLA and KIR as well as immune activation/senescence biomarkers in peripheral blood cells were assessed by SSO-Luminex typing and flow cytometry, respectively. RESULTS: HLA-C*07 is associated with symptomatic HAND. The frequency of two copies of HLA-C*07 was higher in patients with symptomatic than with asymptomatic HAND (12.0 vs. 2.2%, ρ < 0.001). The percentage of senescent CD8+CD28- T-cells was higher in patients with two copies of HLA-C*07 (ρ < 0.05). In patients with symptomatic HAND, the percentages of non-senescent CD8+CD28+ T cells were inversely proportional to the number of copies of the HLA-C*07 (ρ < 0.05). CONCLUSION: Patients with symptomatic HAND showed a higher frequency of the homozygotic unstable HLA-C*07 allotype, which could be associated with neurocognitive complications. Two copies of HLA-C*07 were associated with immune senescent T lymphocyte profiles characterized by the loss of CD28 expression.

Feasibility of a multifaceted educational strategy for strengthening rural primary health care / Factibilidad de una estrategia educativa multifacética para fortalecer la atención primaria rural

Abstract: Objective: To evaluate the feasibility and acceptability of a comprehensive educational strategy designed to improve care quality in rural areas of Mexico. Materials and methods: A demonstration study was performed in 18 public rural health centers in Mexico, including an educational intervention that consists of the following steps: Development of the strategy; Selection and training of instructors (specialist physicians from the referral hospital and multidisciplinary field teams); Implementation of the strategy among health care teams for six priority causes of visit, through workshops, individual tutorials, and round-table case-review sessions. Feasibility and acceptability were evaluated using checklists, direct observation, questionnaires and in-depth interviews with key players. Results: Despite some organizational barriers, the strategy was perceived as worthy by the participants because of the personalized tutorials and the improved integration of health teams within their usual professional practice. Conclusion: The educational strategy proved to be acceptable; its feasibility for usual care conditions will depend on the improvement of organizational processes at rural facilities.

Perfil epidemiológico general de las quejas médicas atendidas en la Comisión Nacional de Arbitraje Médico: 1996-2007 / Epidemiological general profile of complaints treated at the National Medical Arbitration Commission: 1996-2007

OBJECTIVE: To analyze medical complaints over a period of 11 years, for making recommendations for prevention and improving planning for responding. MATERIAL AND METHODS: We studied the medical complaints at the National Medical Arbitration Commission (Conamed, per its acronym in Spanish) between 1996 and 2007 using descriptive statistics to identify their general profile in relation to the variables of time, place and person. We also studied the frequency of evident medical malpractice as well as the severity of the damage it produces. RESULTS: The request for responses to medical complaints increased between 1996 and 2007 and there was less demand between July and December. Two states in the country account for 69.7 percent of the complaints and 74.0 percent are from public institutions. Fifty-eight percent come from women and the 25-34 and 65+ age groups have the highest percentage. We found in 27.0 percent of the complaints there is evidence of medical malpractice and obstetrics and gynecology have the highest percentage of complaints, physical harm and severity of injury. Complaints about treatment are nearly four times more than diagnosis. CONCLUSIONS: It is necessary to improve the quality of diagnosis and treatment and identify cost-effective measures to reduce medical malpractice and the severity of physical damage in patients.

OBJETIVO: Analizar las quejas médicas atendidas en un periodo de 11 años con el fin de formular recomendaciones para prevenirlas y mejorar la planeación para su atención. MATERIAL Y MÉTODOS: Se estudiaron las quejas de la Comisión Nacional de Arbitraje Médico (Conamed) recibidas entre 1996 y 2007 y se utilizaron medidas de estadística descriptiva para conocer su perfil general en relación con las variables de tiempo, lugar y persona. También se determinó la frecuencia de mala práctica médica evidente, así como la gravedad del daño que producen. RESULTADOS: La solicitud de atención de quejas se incrementó entre 1996 y 2007, y existió menor demanda de atención en julio y diciembre. Dos estados del país concentran 69.7 por ciento de las quejas y 74 por ciento proviene de instituciones públicas. El 58 por ciento son de mujeres y los grupos de 25 a 34, y de 65 y más años tienen el mayor porcentaje. En 27 por ciento de las quejas atendidas hay evidencia de mala práctica médica y ginecología y obstetricia presenta el mayor porcentaje de quejas, daño físico y gravedad del daño. Las quejas por tratamiento son casi cuatro veces más que las de diagnóstico. CONCLUSIONES: Es necesario mejorar la calidad del diagnóstico y el tratamiento e identificar medidas efectivas para el costo que reduzcan la mala práctica médica y la gravedad del daño físico en los pacientes.

Migración y ruralización del SIDA: relatos de vulnerabilidad en comunidades indígenas de México / Migration and ruralization of AIDS: reports on vulnerability of indigenous communities in Mexico

OBJETIVO: Analizar la vulnerabilidad para ITS/VIH entre mujeres Purépechas y Zapotecas unidas en concubinato con varones que practican sexo sin protección. MÉTODOS: Estudio etnográfico realizado en febrero del 2004 y en diciembre del 2005 en localidades indígenas de Michoacán y Oaxaca, Mexico. Estos son entidades con niveles altos de expulsión migratoria, rezago comunitario y casos registrados de VIH/SIDA. Se entrevistaron en profundidad a 91 personas: migrantes temporales (24), mujeres indígenas (33), autoridades locales (20) y personal de salud (14). RESULTADOS: La ruralización del ITS/VIH puede relacionarse con las prácticas de iniciación sexual femeninas pero sobre todo con el miedo del migrante a que su concubina tenga relaciones extra-conyugales en su ausencia. El embarazo y la crianza son recursos masculinos de control de las esposas. CONCLUSIONES: La migración de retorno implica formas de vulnerabilidad para las mujeres indígenas en las localidades estudiadas, cuya sexualidad tiene un remarcado carácter reproductivo. Es necesario implementar políticas de prevención para ITS/VIH dirigidas a fortalecer derechos sexuales y reproductivos de las mujeres y que tomen en cuenta aspectos de identidad sexual masculina.

OBJECTIVE: To evaluate the vulnerability for STI/HIV among Mexican indigenous women in common law marriage with men who practice sex without condom. METHODS: Ethnography study undertaken in indigenous villages of Michoacán and Oaxaca, Mexico, in February 2004 and December 2005. These rural communities are characterized by high migration rates, extreme poverty and HIV/AIDS cases. An in-depth interview was applied to transient migrants (24), indigenous women (33), local authorities (20) and health providers (14). RESULTS: Rural propagation of STI/HIV is associated to sexual female initiation and mostly to migrants' fear their concubines will have extramarital sex during their absence. Impregnating their wives and the resulting childcare is one of the men's resources for controlling their concubines. CONCLUSIONS: Return migration implies vulnerability for indigenous women in the rural communities studied whose sexuality has a strong reproductive profile. It is necessary to develop prevention campaigns against STI/HIV taking into account male sexual identities to improve women rights to sexual and reproductive health.

Reestenosis clínica en pacientes diabéticos con implante de stents liberadores de fármaco en lesiones de novo / Clinical restenosis in diabetic patients treated with drug eluting stents for de novo lesions

We evaluated immediate and mid-term clinical and angiographic results in diabetic patients with percutaneous coronary intervention with deployment of drug eluting stents. METHODS: Between November of 2004 and June of 2005 percutaneous coronary interventions were performed 860 with the deployment of 112 drug eluting stents to 42 diabetic patients. The mean of stents was 2.6 per patient, and the type of drug eluting stent was paclitaxel in 60% and sirolimus in 40%. The average of age was 51.2 +/- 9.6 years old. The gender was male in 25 (60%) of patients and female in 17 (40%). The indication of coronary angiography was unstable angina in 15 (35%) patients and stable angina in 27 (65%). There was history of anterior myocardial infarction in 20 (47%), inferior myocardial infarction in 8 (20%) and multiple vessel disease in 16 (38%). The stenosis severity of the lesion was 85.9% +/- 12.2% and the left ventricular function was (55 +/- 10). The hospital stay was 7 +/- 5.4 days. RESULTS: Both clinical and angiographic immediate success was 100%. The average follow was 7.6 +/- 3.3 months in 34 patients (80.9%). The target lesion revascularization (TLR) was 7.1%. (3 patients). Death, myocardial infarction or reinfarction (0%). COMPLICATIONS: One patient (2.3%) developed contrast induced nephropathy. CONCLUSIONS: These results suggest that the use of drug eluting stents (paclitaxel or sirolimus) in diabetic patients has a high rate of success with good angiographic and clinical results and with a low rate of complications or restenosis in this high risk group of patients.

Actividad reumática y disociación clinico-patológica: parámetros clinicos y patológicos en la cardiopatia reumática / Rheumatic activity and clinical-pathological dissociation: clinical-pathological parameter in rheumatic cardiopathy

En las orejuelas y aparatos valvulares resecados de pacientes con cardiopatía reumática clinicamente inactiva, se encuentran en ocasiones lesiones histológicas sugestivas de actividad. Se revisaron 673 especímenes colectados entre 1980 y 1985, y se estudiaron 2 grupos: uno de 31 casos con lesiones histológicas específicas de actividad reumática, y otro, pareado, sin estas. Se buscó en el expediente clínico datos de actividad reumática, usando como base los criterios de Jones modificados. En el primer grupo 45% mostraron lesiones "mal diferenciadas", y 55% granulomas de Aschoff. En todos ellos hubo valvulitis con infiltrado mononuclear. En 8 de estos 31 casos hubo datos de actividad clínica en el lapso preoperatorio estudiado. En el grupo comparativo, sin lesiones histológicas de actividad reumática, sólo en 2 casos se encontró actividad clínica. En la cardiopatía reumática inactiva no se cumplen a satisfacción los criterios de Jones, los brotes de actividad son difíciles de reconocer y no parece haber correlación clínico-histológica. Es posible que la inflamación crónica en el corazón sea órgano-limitada
