Ten cases of advanced and metastatic gastric cancer treated by weekly administration of paclitaxel were studied. The patients were 50-72 years of age, including 9 men and 1 woman. In this study, paclitaxel was administered by 1 hour intravenous infusion at a dose of 50-80 mg/m2 every week. Administration was continued for 3 weeks with 1 week rest. One to four cycles were performed at minimum. Paclitaxel was administered in 5 cases as 1st line treatment, 4 cases as 2nd line treatment and 1 case as 3rd line treatment. There were 2 partial responders and no complete responders, and the overall response rate was 20%. The response rate was 100% in liver, 100% in lung, 16% in lymphnodes, and 0% in peritonial dissemination. The clinical symptoms of pain and jaundice abated in one case, the size of the tumor decreased in one case, and a temporary decrease of ascites due to peritonial dissemination was seen in two cases. The level of tumor marker was decreased in 3 out of 10 cases. Side effects included grade 3/4 leukopenia in 10% of patients, and alopecia in 50%, but peripheral neuropathy was not observed. Weekly administration of paclitaxel appears to be well-tolerated and effective against advanced and metastatic gastric cancer.

TARGETING LUNG HEME IRON BY AEROSOL HEMOPEXIN ADMINSTRATION IN SICKLE CELL DISEASE PULMONARY HYPERTENSION.

Lung tissue from human patients and murine models of sickle cell disease pulmonary hypertension (SCD-PH) show perivascular regions with excessive iron accumulation. The iron accumulation arises from chronic hemolysis and extravasation of hemoglobin (Hb) into the lung adventitial spaces, where it is linked to nitric oxide depletion, oxidative stress, inflammation, and tissue hypoxia, which collectively drive SCD-PH. Here, we tested the hypothesis that intrapulmonary delivery of hemopexin (Hpx) to the deep lung is effective at scavenging heme-iron and attenuating the progression of SCD-PH.

Objectives: Mumps (infectious parotitis) is an acute respiratory illness caused by the mumps virus in humans. While numerous studies have explored the impact of climate variability on mumps incidence in specific cities or regions, few have analyzed nationwide associations across multiple locations. This study aims to systematically assess the short-term effects of meteorological factors on mumps incidence across Japan over a 15-year period.

Department of Medicine, Rawalpindi Medical University, Rawalpindi, Pakistan.
The advent of once-weekly insulin icodec is a promising development in the care of individuals with diabetes. These once-weekly formulations aimed to improve patient adherence and quality of life for patients who find daily injection administration challenging. Insulin icodec has demonstrated comparable glycemic control to conventionally used daily basal insulins, such as insulin glargine and degludec, in the ONWARDS clinical trials.

Background: Recent studies suggest that the anterior limb of the internal capsule may be an area of convergence for multiple compulsion loops. In this study, the role of different dopaminergic compulsion loops in the mechanism of obsessive-compulsive disorder (OCD) was investigated by selectively damaging dopaminergic neurons or fibers in the corresponding targets with 6-hydroxydopamine (6-OHDA) and depicting the anatomical map of various compulsion loops located in the anterior limb of the internal capsule.
Methods: A total of 52 male Sprague Dawley (SD) rats were exposed to either saline (1 mL/kg, NS group, n = 6) or quinpirole (QNP, dopamine D2-agonist, 0.
Interpretation of COVID-19 Epidemiological Trends in Mexico Through Wastewater Surveillance Using Simple Machine Learning Algorithms for Rapid Decision-Making.

Detection and quantification of disease-related biomarkers in wastewater samples, denominated Wastewater-based Surveillance (WBS), has proven a valuable strategy for studying the prevalence of infectious diseases within populations in a time- and resource-efficient manner, as wastewater samples are representative of all cases within the catchment area, whether they are clinically reported or not. However, analysis and interpretation of WBS datasets for decision-making during public health emergencies, such as the COVID-19 pandemic, remains an area of opportunity. In this article, a database obtained from wastewater sampling at wastewater treatment plants (WWTPs) and university campuses in Monterrey and Mexico City between 2021 and 2022 was used to train simple clustering- and regression-based risk assessment models to allow for informed prevention and control measures in high-affluence facilities, even if working with low-dimensionality datasets and a limited number of observations.
