Background:
A 2018 study on the global burden of disease, accidents, and risk factors reported that 1.6 million peo
ple died in 2017 due to household air pollution. Poor indoor air quality has been highlighted as a contributing factor to
respiratory diseases, cardiovascular conditions, and exacerbation of asthma and allergies. A 2019 study estimated that
long-term exposure to fine particulate matter (PM2.5) with a diameter of 2.5 micrometers or less reduces average life
expectancy by 1.8 years, with more severe effects in highly polluted regions. Additionally, a study by Miller et al. (2007)
found that prolonged exposure to PM2.5 increases the risk of cardiovascular diseases, particularly among women. Direct
measurement devices are highly effective in determining indoor PM2.5 concentrations, identifying sources of pollution,
tracking pollutant dispersion, and monitoring temporal variations. Studies suggest that direct measurement is an accurate,
cost-effective method that provides detailed data suitable for local conditions.
Aim:
To investigate the indoor air quality of houses and apartments in Darkhan city during the winter season using the
Purple Air monitoring device.
Materials and Methods:
A cross-sectional study was conducted with a targeted sample of 128 households in Darkhan
city. The study examined factors such as stove type, type of coal used, annual and daily coal consumption, frequency of
heating, and chimney sealing conditions. To collect data, the Purple Air monitoring device was installed in each house
hold for a month, after which it was retrieved. During retrieval, participants completed a questionnaire. The questionnaire
consisted of 55 questions across 7 pages at the time of device installation and 25 questions across 3 pages at the time of
device retrieval. The collected data was analyzed using SPSS 25.0.
Results:
A total of 128 households in Darkhan city participated in the study. The average duration of residence in the
current home was 9.5 years, with no statistically significant variation. The distribution of housing types was as follows:
traditional Mongolian gers (40.6%), houses (39.1%), and apartments (20.3%). The 24-hour average PM2.5 concentration
was highest in gers (70.9 μg/m³), followed by houses (46.8 μg/m³) and apartments (22.8 μg/m³), with a statistically significant difference (p=0.0001). PM2.5 levels were most variable in gers, followed by houses and then apartments. House
holds using central heating (apartments) had an average 24-hour PM2.5 concentration of 22.8 μg/m³, whereas households
using stoves (gers and houses) had a significantly higher concentration of 59.4 μg/m³ (p=0.0001). However, there was
no statistically significant difference between traditional and improved stoves. Among study participants, 21.4% reported
that someone in their household smoked indoors. Additionally, 86.5% regularly burned incense, candles, or herbs, while
99.2% did not use an air purifier.
Conclusion
The indoor particulate matter concentration in houses and gers in Darkhan was 59.4μг/m3. Variations in
stove types, poor chimney sealing limited space, and frequent gaps and cracks contribute to increased spread of indoor
air pollutants.

The central nervous system regulates feeding, weight and glucose homeostasis in rodents and humans, but the site-specific mechanisms remain unclear. The dorsal vagal complex in the brainstem that contains the nucleus of the solitary tract (NTS) and area postrema (AP) emerges as a regulatory center that impacts energy and glucose balance by monitoring hormonal and nutrient changes. However, the specific mechanistic metabolic roles of the NTS and AP remain elusive. This mini-review highlights methods to study their distinct roles and recent findings on their metabolic differences and similarities of growth differentiation factor 15 (GDF15) action and glucose sensing in the NTS and AP. In summary, future research aims to characterize hormonal and glucose sensing mechanisms in the AP and/or NTS carries potential to unveil novel targets that lower weight and glucose levels in obesity and diabetes.

The final analysis of the phase 3 Targeted Investigational Treatment Analysis of Novel Anti-androgen (TITAN) trial showed improvement in overall survival (OS) and other efficacy endpoints with apalutamide plus androgen deprivation therapy (ADT) versus ADT alone in patients with metastatic castration-sensitive prostate cancer (mCSPC). As ethnicity and regional differences may affect treatment outcomes in advanced prostate cancer, a post hoc final analysis was conducted to assess the efficacy and safety of apalutamide in the Asian subpopulation. Event-driven endpoints were OS, and time from randomization to initiation of castration resistance, prostate-specific antigen (PSA) progression, and second progression-free survival (PFS2) on first subsequent therapy or death. Efficacy endpoints were assessed using the Kaplan-Meier method and Cox proportional-hazards models without formal statistical testing and adjustment for multiplicity. Participating Asian patients received once-daily apalutamide 240 mg ( n = 111) or placebo ( n = 110) plus ADT. After a median follow-up of 42.5 months and despite crossover of 47 placebo recipients to open-label apalutamide, apalutamide reduced the risk of death by 32% (hazard ratio [HR]: 0.68; 95% confidence interval [CI]: 0.42-1.13), risk of castration resistance by 69% (HR: 0.31; 95% CI: 0.21-0.46), PSA progression by 79% (HR: 0.21; 95% CI: 0.13-0.35) and PFS2 by 24% (HR: 0.76; 95% CI: 0.44-1.29) relative to placebo. The outcomes were comparable between subgroups with low- and high-volume disease at baseline. No new safety issues were identified. Apalutamide provides valuable clinical benefits to Asian patients with mCSPC, with an efficacy and safety profile consistent with that in the overall patient population.

Objective: To investigate the clinicopathological features, immunophenotype and prognosis of nuclear protein in testis (NUT) midline carcinoma. Methods: Twenty-four resection cases of NUT midline carcinoma diagnosed at the Department of Pathology, Cancer Hospital, Chinese Academy of Medical Sciences and Peking Union Medical College, Beijing, China from January 2018 to September 2022, were collected, and retrospectively analyzed for their clinicopathological characteristics. Relevant literature was reviewed. Results: All 24 cases of NUT midline carcinoma occurred in the chest or head and neck, including 14 men and 10 women, with a median age of 40 years. Histological examination showed that the tumors were poorly differentiated, with solid nested or sheet-like arrangement, small to medium-sized cells, sparse cytoplasm and coarse granular chromatin, including 5 cases with abrupt squamous epithelial differentiation. Immunohistochemistry showed that all 24 cases were positive for NUT protein, while 16 cases were p63 positive, 19 cases were p40 positive, 15 out of 18 cases were CK5/6 positive. Follow-up data were obtained for 21 patients (follow-up time range, 1-21 months), of which 11 survived, 10 died, and 3 were lost to follow-up. Conclusions: NUT midline carcinoma is a rare and highly aggressive malignancy with unique histological, immunophenotypic and molecular features. It has a poor prognosis.
