The associations between the presence of triatomines and environmental variables were studied using correlation analysis and logistic regression models for a sample of villages in the south-eastern provinces of Guatemala. Information on the presence of Triatoma dimidiata, T. nitida and Rhodnius prolixus came from entomological surveys carried out by the Ministry of Health of Guatemala as part of its vector control programme. Environmental information for each village was extracted from digital thematic maps developed by the Ministry of Agriculture. The presence of T. nitida was found to be significantly associated with the average minimum temperature. The odds of presence of T. nitida in a village decreased as the average minimum temperature increased. T. nitida exists at altitudes above 1000 m above sea level in temperate regions. The presence of R. prolixus showed a significant positive association with maximum absolute temperature and relative humidity. The logistic regression model for R. prolixus showed a good fit and predicted suitable habitats in the provinces of Chiquimula, Zacapa and Jalapa, which agrees with the known distribution of the species. Habitat partitioning between R. prolixus and T. dimidiata is suggested by their significant and opposite associations with maximum absolute temperature. Improved models to predict suitable habitats for T. dimidiata hold promise for spatial targeting of integrated vector management.

Background: Perianal fistula is one of the complications of deepened anal fissure. The present case-control study aimed to assess the risk factors of fissure-associated fistulas due to the limited available evidence.
Methods: Patients with fissure-associated fistulas were considered as case, and patients with anal fissure who were undergoing medical treatment without any previous anorectal surgeries were considered as control group.

Background: Fluid balance gap (FBgap-prescribed vs. achieved) is associated with hospital mortality. Downtime is an important quality indicator for the delivery of continuous renal replacement therapy (CRRT).

Background: There are limited and controversial findings concerning ovulation induction using intrauterine and intramuscular human chorionic gonadotropin (hCG) injection compared to intramuscular hCG alone. The study aimed to examine the impact of intrauterine hCG injection, which is used to induce ovulation, on the efficacy of the intrauterine insemination (IUI) technique in patients with unexplained infertility.
Methods: A randomized controlled clinical trial was conducted involving 80 subjects with unexplained primary infertility at the infertility clinic of Al-Zahra Hospital in northwest Iran.

Objective: This study aims to explore the predictive value of endplate morphology and pedicle screw bone quality score on screw loosening after single-level lumbar spinal fusion surgery.
Methods: A retrospective analysis was conducted on the clinical data of 207 patients who underwent single-level lumbar spinal fusion (34 in the screw loosening group and 173 in the non-screw loosening group). Univariate analysis and binary logistic regression model analysis were performed using SPSS 27.

Background: Indoor air pollution (IAP) is the major contributor (26%) to TB, in addition to other socioeconomic and environmental factors. It occurs in most developing countries like India, where people rely on the combustion of biomass-based solid fuels (low combustion efficiency and high pollution emissions) due to the prevailing socio-economic conditions. However, this cause-and-effect relationship between TB and IAP has not been studied much.
