RESUMO
Patients with hypertensive disorders of pregnancy (HDP) are at increased risk of maternal-fetal complications and represent the third leading cause of maternal mortality. To date, it is known that women experiencing this condition during pregnancy have a higher future risk of cardiovascular events (CVD). Our objective was to report the incidence of new-onset hypertension in the postpartum period. We conducted a cohort study in high-risk pregnant patients who underwent ambulatory blood pressure monitoring (ABPM) between weeks 20-30. Patients were categorized as normotensive (NT) or gestational hypertensive (GH), excluding those with chronic hypertension, and were followed until the end of pregnancy with a postpartum assessment after 3months. Patients with HDP (39%) had a higher incidence of preeclampsia and newborns with low birth weight and preterm birth. A total of 177 pregnant women were analyzed for the primary outcome. Among those with GH, 33.3% vs 17.2% of NT (P=.014) reported new-onset hypertension. The odds ratio for developing new-onset hypertension was 2.3 (95%CI: 1.20-4.77), for those with GH. In conclusion, pregnant patients with GH assessed by ABPM between 20-30weeks are at higher risk of developing new-onset hypertension in the postpartum period, emphasizing the need for closer monitoring and control to prevent future cardiovascular complications.
RESUMO
Treatment of penile cancer (PC) focuses on organ preservation, employing various surgical and non-surgical approaches. These interventions may lead to disfigurement, impacting patients' functional outcomes and psychosocial well-being. We reviewed studies related to penile health and PC up to February 2024, limited to studies published in English. Studies employing health-related quality of life (HRQoL) assessments have identified a detrimental association between aggressive treatment and overall health status, physical functioning, and relationships. In contrast, organ-sparing demonstrates improved measures related to HRQoL and sexual function. Assessment through validated questionnaires reveals diverse voiding outcomes, and varying impacts on QoL and sexual activity, emphasizing the necessity for multidisciplinary personalized care. Studies highlight substantial variations in sexual function, with patients reporting adaptations, reduced satisfaction, and concerns about body image and sexual well-being. Furthermore, unmet needs include challenges in patient-clinician communication, obtaining information, and accessing psychosocial support. Patient experiences underscore the importance of timely diagnosis, treatment access, and addressing psychological consequences. Organ-sparing approaches have higher QoL preservation and sexual function. Individualized support, including sexual therapy, support groups, and family counseling, is essential for post-treatment rehabilitation. Timely diagnosis and comprehensive care are paramount in addressing the multifaceted impact of PC on patients and families.
RESUMO
Objetivo: Determinar la ancestría de Helicobacter pylori aislado de pacientes provenientes de una zona de alto riesgo de cáncer gástrico del departamento de Nariño. Materiales y Métodos: Se incluyeron 16 pacientes con síntomas de dispepsia e infectados con Helicobacter pylori. Se utilizaron biopsias gástricas para el cultivo de Helicobacter pylori y subsecuente secuenciación del genoma total por Illumina MiSeq, 2x300 pb. El ensamblaje y anotación de los genomas se procedió mediante el uso de los algoritmos SPAdes y RASTtk. Las proporciones ancestrales de Helicobacter pylori se determinaron por STRUCTURE con el modelo de mezcla. Las diferencias entre estas proporciones se establecieron con las pruebas H de Kruskal Wallis y post hoc. Resultados: La estructura de la población de Helicobacter pylori deriva de cuatro poblaciones ancestrales: Ancestral Europa (AE) (61.2%), Ancestral Africa1 (AA1) (35.7%), Ancestral Este de Asia (AEA) (3%) y Ancestral Africa2 (AA2) (0.1%), siendo significativas las diferencias entre las proporciones de los ancestros de Helicobacter pylori (p<0.05). Se identificaron diferencias estadísticamente significativas entre: AA2 y AEA (p=0.022); AA2 y AA1 (p<0.05); AA2 y AE (p<0.05); AEA y AA1 (p=0.014) y AEA con AE (p<0.05), sin embargo, no se encontró diferencias significativas entre AA1 y AE (p=0.098), evaluadas por post hoc. Conclusión: Helicobacter pylori que coloniza la mucosa gástrica de una población de alto riesgo de cáncer gástrico en Nariño, deriva su acervo genético principalmente de ancestros europeos y africanos, confiriéndole a la bacteria alta capacidad competitiva asociada al desarrollo de lesiones severas en nichos gástricos amerindios.
Objective: To determine the ancestry of Helicobacter pylori isolated from patients from a high-risk area for gastric cancer in the department of Nariño. Materials and Methods: Sixteen patients with dyspepsia symptoms and infected with Helicobacter pylori were included. Gastric biopsies were used for Helicobacter pylori culture and subsequent whole genome sequencing by Illumina MiSeq, 2x300 bp. Genome assembly and annotation proceeded by using the SPAdes and RASTtk algorithms. The ancestral proportions of Helicobacter pylori were determined by STRUCTURE with the mixture model. Differences between these proportions were established with Kruskal Wallis and post hoc H-tests. Results: The population structure of Helicobacter pylori derived from four ancestral populations: Ancestral Europe (AE) (61.2%), Ancestral Africa1 (AA1) (35.7%), Ancestral East Asia (AEA) (3%) and Ancestral Africa2 (AA2) (0.1%), with differences between the proportions of Helicobacter pylori ancestors being significant (p<0.05). Statistically significant differences were identified between: AA2 and AEA (p=0.022); AA2 and AA1 (p<0.05); AA2 and AE (p<0.05); AEA and AA1 (p=0.014) and AEA with AE (p<0.05), however, no significant differences were found between AA1 and AE (p=0.098), evaluated by post hoc. Conclusion: Helicobacter pylori colonizing the gastric mucosa of a population at high risk of gastric cancer in Nariño, derives its gene pool mainly from European and African ancestors, giving the bacterium highly competitive capacity associated with the development of severe lesions in Amerindian gastric niches.

PURPOSE: The aim of this study was to identify the risk factors associated with house infestation by Triatoma dimidiata as well as with Trypanosoma cruzi infection in humans and owned dogs in two rural communities from the municipality of Catemaco, Veracruz, Mexico. METHODS: One hundred and 16 human blood samples and 34 dog blood samples were collected. The presence of anti-T. cruzi antibodies was determined using four different ELISA assays. Moreover, reactive ELISA sera from humans and dogs were processed by indirect immunofluorescence (IFI) to confirm the presence of anti-T. cruzi antibodies. RESULTS: Serologic tests for T. cruzi infection showed a prevalence of 5.1% (6/116) in humans and of 50% (17/34) in owned dogs. CONCLUSION: The presence of animals (dogs, chickens and wild animals), as well as some characteristics of house construction were identified as risk factors for infestation and infection. Complementary studies must be carried out to allow a better understanding of the transmission dynamics in the state of Veracruz, Mexico, and the implementation of adequate control programs.

BACKGROUND: The outbreak of SARS-CoV-2 abruptly disseminated in early 2020, overcoming the capacity of health systems to respond the pandemic. It was not until the vaccines were launched worldwide that an increase in survival was observed. The objectives of this study were to analyse the characteristics of survivors and their relationship with comorbidities. We had access to a database containing information on 16,747 hospitalized patients from Mexico, all infected with SARS-CoV-2, as part of a regular follow-up. The descriptive analysis looked for clusters of either success or failure. We categorized the samples into no comorbidities, or one and up to five coexisting with the infection. We performed a logistic regression test to ascertain what factors were more influential in survival. The main variable of interest was survival associated with multimorbidity factors. The database hosted information on hospitalized patients from Mexico between March 2020 through to April 2021. Categories 2 and 3 had the largest number of patients. Survival rates were higher in categories 0 (64.8%), 1 (57.5%) and 2 (51.6%). In total, 1741 (10.5%) patients were allocated to an ICU unit. Mechanical ventilators were used on 1415 patients, corresponding to 8.76%. Survival was recorded in 9575 patients, accounting for 57.2% of the sample population. Patients without comorbidities, younger people and women were more likely to survive.
RESUMO
BACKGROUND: Campylobacter fetus subsp. fetus is the causal agent of sporadic abortion and infertility in bovines that produces economic losses in livestock. AIMS: This study evaluates the capability of C. fetus subsp. fetus to invade and survive in bovine endometrial epithelial cells and attempts to describe a pathogenic mechanism of this microorganism. METHODS: Primary culture of bovine endometrial epithelial cells was challenged with C. fetus subsp. fetus. Intracellular bacteria, represented by the number of genomic copies (g.c.) were quantified at 0, 2, 4, 10, and 24 hours post-infection (h.p.i.), by quantitative polymerase chain reaction (qPCR). The presence of intracellular bacteria was evaluated by immunofluorescence and immunohistochemistry. RESULTS: The results showed that only viable C. fetus subsp. fetus could invade endometrial cells. The g.c. number in assays with viable C. fetus subsp. fetus reached an average value of 656 g.c., remained constant until 4 h.p.i., then decreased to 100 g.c, at 24 h.p.i. In assays with non-viable microorganisms, the average value of g.c. was less than 1 g.c. and never changed. The intracellular presence of this bacteria was confirmed at 2 h.p.i. by immunofluorescence and immunohistochemistry. CONCLUSION: The results suggest that only C. fetus subsp. fetus viable can invade bovine endometrial epithelial cells but will not replicate in them, indicating that the endometrial cells do not represent a replication niche for this pathogen. Nonetheless, this invasion capability suggests that this type of cell could be employed by the pathogen to spread to other tissues.
RESUMO
INTRODUCTION: The aim of this study was to analyze the associations between perceived social support and sociodemographic variables on coping strategies. METHODS: A prospective, cross-sectional, multicenter study was conducted in 404 women with resected, non-metastatic breast cancer. Participants completed questionnaires: perceived social support (MSPSS), coping strategies (Mini-MAC), and psychological distress (BSI-18). RESULTS: Sociodemographic factors as age, education, and partnership status were associated with coping strategies. As for maladaptive strategies, hopelessness was more frequent in older people and lower educational level; fatalism in older and single people, and cognitive avoidance was associated with lower educational level. Suppor t from family, friends, and partners was associated with a greater fighting spirit. In contrast, high psychological distress (anxiety and depression) was associated with greater use of maladaptive strategies. CONCLUSION: Young people, a high level of education, having a partner, low psychological distress, and seeking social support were associated with the use of adaptive cancer coping strategies.

BACKGROUND AND RATIONALE: Thromboembolic complications are a serious, preventable and common event in cancer patients that contributes to increasing morbidity and mortality. Despite increasing knowledge on cancer-associated thrombosis (CAT), there are still several aspects of diagnosis, clinical management, treatment and prognosis with uncertainties that are under-represented in randomized clinical trials. For this reason, the Spanish Society of Medical Oncology (SEOM) launched in June 2018 a registry of CAT. METHODS/DESIGN: TESEO is an ongoing prospective, non-interventional, multicentric study in consecutive cancer patients with newly diagnosed of thromboembolic event (TEE). Eligibility criteria include being > 18 years with a histologically confirmed diagnosis of cancer and a symptomatic or incidental TEE confirmed with an imaging technique in the previous month or any time after the cancer diagnosis and signing of informed consent. The study consists of two types of integrated but independent prospective registries. Regular CAT sub-registry includes information on patient's cancer´s characteristics, anticoagulant treatment provided and outcome data. Special CAT sub-registry includes variables related to special situations of CAT that comprise patients with severe kidney failure, thrombocytopenia, high risk of bleeding related to the cancer or with coexistence of bleeding and patients who receive new treatments such a targeted therapy, antiangiogenics agents and immunotherapy. The registry considers the status of the cancer and the time to assess how the prognosis is changed based on when the thrombus occurs. Some outcomes such as rethrombosis, major bleeding, tumor progression and survival will be valued in various time intervals including 1, 3, 6 and 12 months after the even in the first year; and then every 6 months until the patient's death. RESULTS: After 18 months and with 35 centers and researchers, the registry has 1128 patients. CONCLUSION: TESEO registry will provide clinical real-world evidence for prevention, treatment and complications of CAT in different scenarios that are under-represented in randomized clinical trials.

OBJECTIVE: To identify distinct trajectories of toxicity in colorectal cancer (CRC) patients after adjuvant chemotherapy and its impact on quality of life (QoL) and psychological symptoms. METHODS: A prospective, multicenter study was conducted in 157 patients. A latent class analysis defined the unobserved latent constructs that can be predicted as symptom clusters, considering the intensity of four types of adverse events (AEs). Patients completed EORTC-QLQ-C30, BSI-18, PDRQ-9, and DRS scales. RESULTS: Ninety-six percent had some degree of toxicity, with grades 3-4 being the most common: neurotoxicity (7.2%), hematological (13.1%), digestive (5.2%), and skin toxicity (1.4%). Three distinct latent classes were identified (high [72.5%], mild [16.9%], and low [10.6%] toxicity). Patients with high toxicity had the worst QoL scores and moderately high somatization and psychological distress scores. CONCLUSIONS: Adjuvant chemotherapy for CRC was associated with frequent toxicity that negatively impacted QoL and psychological wellbeing.

The mechanisms of infection and dispersion of Trypanosoma cruzi among animals, especially in the sylvatic environment, are still not entirely clear, and various aspects of the transmission dynamics of this parasite in the sylvatic environment are still unknown. T. cruzi is a parasite with a great biological and genetic diversity that infects a wide variety of hosts, therefore, transmission cycles of this parasite are complex. The objective of this study was to determine the prevalence of T. cruzi infection and analyze the genetic variability of the discrete typing units (DTUs) of the parasite in three non-human primate species (Alouatta palliata, Alouatta pigra, and Ateles geoffroyi) in southeastern Mexico. A total of one hundred sixty-four serum samples (42 samples of A. pigra, 41 samples of A. palliata (free-ranging) and 81 samples of A. geoffroyi (hosted in care centers)) were analyzed for the detection of anti-T. cruzi antibodies by ELISA assays. The seroprevalence of infection was 23.39% in A. palliata, 21.40% in A. pigra and 16.27% in A. geoffroyi. Additionally, presence of parasite DNA was assessed by PCR, and the identification of DTUs was performed by real-time PCR coupled to High Resolution Melting (qPCR-HRM). Different DTUs (TcI, TcII, TcIII, TcV and TcVI) were found in the analyzed monkeys. In addition, infection of monkeys was not associated with age or gender, but it was associated with the species. This study reveals the risk of infection in the study area and that the different DTUs of the parasite can coexist in the same habitat, indicating that T. cruzi transmission in the study area is very complex and involves many ecological factors. However, there is a need for long-term studies of host-parasite interactions to provide a solid understanding of the ecology of these species and to understand the dispersion strategies of T. cruzi.
