Published: September 2017

The official air-quality statistic reported that Beijing had a 9.9% decline in the annual concentration of PM in 2016. While this statistic offered some relief for the inhabitants of the capital, we present several analyses based on Beijing's PM data of the past 4 years at 36 monitoring sites along with meteorological data of the past 7 years. The analyses reveal the air pollution situation in 2016 was not as rosy as the 9.9% decline would convey, and improvement if any was rather uncertain. The paper also provides an assessment on the city's PM situation in the past 4 years.

Background: /purposeSince 1995, Taiwan's National Health Insurance (NHI) has offered a comprehensive dental coverage to over 99 % of the population. This study mainly analyzed the dental service utilization and expenditure trends by the gender, age, and service type and evaluated the resource allocation across different demographics from 2000 to 2020.

Materials And Methods: Nationwide NHI administrative data were used to assess the dental visit rates, average visits per user, and per capita expenditure by the gender, age, and 11 service categories for the years 2000, 2005, 2010, 2015, and 2020.

Objectives: The aim of the study was to assess the association between the geriatric nutritional risk index (GNRI) and incidence of CKD progression, all-cause mortality, and cardiovascular events in the elderly patients with chronic kidney disease (CKD) before dialysis initiation.

Methods: We performed a post hoc analysis of the CKD-ROUTE database, which included 538 pre-dialysis CKD patients aged ≥65 years in this prospective cohort study. Associations between GNRI and clinical outcomes were estimated using Cox proportional hazards model analysis.

Background: Under-5 children have been known to bear a significant burden of malaria in endemic countries. Though significant progress has been made towards malaria prevention and control in Nigeria, it is expected that the addition of new malaria prevention strategy, such as perennial malaria chemoprevention (PMC) can contribute to a more rapid decline in malaria cases. This study aimed to determine the prevalence and factors associated with malaria and anaemia among children aged 2-18 months in Osun State.

Introduction/aims: Literature on the role of gastrostomy and noninvasive ventilation (NIV) in primary lateral sclerosis (PLS) is limited. We aim to investigate whether PLS patients develop dysphagia requiring feeding tubes or respiratory failure necessitating NIV.

Methods: We conducted a retrospective study of PLS patients with a definite diagnosis followed at our center (1994-2024).

Background: Insulin resistance and the G allele of rs738409 interact to create a greater risk of metabolic dysfunction-associated steatotic liver disease.

Objective: This study aims to confirm that one promising way to reduce insulin resistance is by following a very low-carbohydrate (VLC) dietary pattern.

Methods: Adults with rs738409-GG or -CG with liver steatosis and elevated liver function tests, were taught an ad libitum VLC diet, positive affect and mindful eating skills, goal setting, and self-monitoring and given feedback and coaching for 4 months.
