Objective:To investigate the iodine nutrition status of children aged 8 - 10 and pregnant women in Xining City, Qinghai Province.Methods:From 2019 to 2021, a stratified cluster sampling method was used to divide 7 counties (districts) under the jurisdiction of Xining City, Qinghai Province into 5 sampling areas according to east, west, south, north, and center each year. One township (town, street) was selected from each area. Forty non boarding students aged 8 to 10 from each primary school (half male and half female, age balanced) and 20 pregnant women from each township (town, street) location were selected to collect edible salt samples at home and a random urine sample to measure salt iodine and urinary iodine level. B-ultrasound was used to measure thyroid volume in children and the goiter rate was calculated.Results:A total of 6 534 samples of household edible salt were collected from children and pregnant women, with an average salt iodine concentration of 25.58 mg/kg. The coverage rate of iodized salt was 97.50% (6 371/6 534), and the qualified iodized salt consumption rate was 89.46% (5 845/6 534). A total of 4 362 urine samples were collected from children, with a median urinary iodine level of 183.10 μg/L. The difference between different years was statistically significant ( H = 20.27, P < 0.001). A total of 2 169 urine samples were collected from pregnant women, with a median urinary iodine level of 168.90 μg/L. The difference between different years was statistically significant ( H = 107.09, P < 0.001). A total of 3 336 cases of thyroid gland examination were conducted in children, including 33 cases of thyroid enlargement, with a goiter rate of 0.99%. There was a statistically significant difference between different years (χ 2 = 15.00, P < 0.001). Conclusion:From 2019 to 2021, children aged 8 to 10 and pregnant women in Xining City are at an appropriate level of iodine, and the achievements in prevention and treatment of iodine deficiency disorders still need to be continuously consolidated.

Body weight abnormalities, including overweight, obesity, and underweight, have become a dual public health challenge in Chinese adults: overweight and obesity lead to a variety of chronic complications, while underweight increases the risks of malnutrition, sarcopenia, and organ dysfunction. To systematically address these issues, multidisciplinary experts in endocrinology, sports science, nutrition, and psychiatry from various regions have held multiple weight management seminars. Based on the latest epidemiological data and clinical evidence, they expanded the guideline to include assessment and intervention strategies for underweight, in addition to the core content of obesity management. This guideline outlines the etiological mechanisms, evaluation methods, and multidimensional management strategies for overweight and obesity, covering key areas such as diagnosis and assessment, medical nutrition therapy, exercise prescription, pharmacological intervention, and psychological support. It is intended to provide a scientific and standardized approach to weight management across the adult population, aiming to curb the rising prevalence of obesity, mitigate complications associated with abnormal body weight, and improve nutritional status and overall quality of life.

With the aging population in China,health issues among the elderly are becoming increasingly prominent,leading to a rapidly growing demand for health interventions for the elderly.Exergames are one of the important emerging methods in the field of health interventions for the elderly,widely used and yielding positive results.While research on exergames is well-established abroad,it is still in its infancy in China,lacking reports on the types,interaction forms,intervention content,application status,and effectiveness of exergames.Exergames are suitable for widespread use among the elderly in China,and there is a need to accelerate the development and application of exergames in the field of health interventions for the elderly in China.

Objective:To analyze research hotspots and trends in forensic mental health nursing internationally.Methods:The Web of Science Core Collection Database was searched for research on forensic mental health nursing, with the search period covering the database's inception to December 31, 2023. CiteSpace 6.1.R4 and VOSviewer 1.6.19 were used to visually analyze research hotspots and trends in forensic mental health nursing.Results:From 1992 to 2023, the volume of publications on forensic mental health nursing steadily increased, with the highest number of publications in 2022 (155 papers). The United Kingdom had the most publications (455 papers), and King's College London was the leading institution (50 papers). The Journal of Forensic Psychiatry was the most frequently published (120 papers). Research hotspots in forensic mental health nursing included forensic mental health care for trauma victims, forensic mental health rehabilitation and forensic mental health nursing management, risk assessment in forensic mental health care, and forensic mental health nursing for schizophrenia. Trauma care for forensic mental health patients became a new research trend. Conclusions:Interest in forensic mental health nursing research is rising internationally. Domestic research can benefit from these trends to promote the development of forensic mental health.

Objective:To systematically evaluate the risks of gastrointestinal reactions induced by sodium-glucose transporter 2 (SGLT2) inhibitors in patients with type 2 diabetes mellitus.Methods:Randomized controlled trials of SGLT2 inhibitors in the treatment of type 2 diabetes mellitus, in which gastrointestinal reactions were evaluated as one of outcome indicators, were collected by searching relevant databases at home and abroad (up to December 30, 2022). Cochrane risk of bias assessment tool was used to evaluate the quality of the included studies. Stata 15.1 software was used to conduct Bayesian network meta-analysis, including drawing the network evidence plot, the league map of pairwise comparison, and the surface under the cumulative ranking curve (SUCRA) for gastrointestinal reaction risks with different interventions of SGLT2 inhibitors, and ranking the risks of gastrointestinal reaction of different interventions of SGLT2 inhibitors. The effect sizes of gastrointestinal reaction were expressed by relative risk ( RR) and its 95% confidence interval ( CI). Results:A total of 15 studies were included in the analysis, involving 5 540 patients with 3 949 in the SGLT2 inhibitor treatment group and 1 591 in the control group. Drugs that used in the treatment group included dapagliflozin (in 1 872 patients), canagliflozin (in 1 100 patients), empagliflozin (in 649 patients), ertugliflozin (in 219 patients), ipragliflozin (in 61 patients), and licogliflozin (in 48 patients). All patients in the control group were treated with placebo. The results of the network meta-analysis showed that the risk of gastrointestinal reactions was higher after treatment with 10 mg of ertugliflozin, compared with those with 50 mg and 100 mg of canagliflozin ( RR=1.37, 95% CI: 1.02-3.48; RR=2.98, 95% CI: 1.19-4.09; all P<0.05). There was no statistically significant difference in comparison between other interventions with SGLT2 inhibitors. According to the results of SUCRA on the relative risks for gastrointestinal reactions of different interventions with SGLT2 inhibitors, interventions were ranked as licogliflozin 50 mg, ertugliflozin 25 mg, ertugliflozin 10 mg, empagliflozin 25 mg, ipragliflozin 100 mg, ipragliflozin 300 mg, ipragliflozin 200 mg, ertugliflozin 5 mg, licogliflozin 10 mg, ipragliflozin 50 mg, empagliflozin 10 mg, licogliflozin 2.5 mg, dapagliflozin 20 mg, dapagliflozin 10 mg, empagliflozin 5 mg, ertugliflozin 1 mg, dapagliflozin 5 mg, placebo, canagliflozin 300 mg, canagliflozin 200 mg, dapagliflozin 2.5 mg, dapagliflozin 1 mg, canagliflozin 100 mg, canagliflozin 50 mg. Conclusions:Different SGLT2 inhibitor treatment regimens lead to different risks of gastrointestinal reactions in patients with type 2 diabetes. The risk of gastrointestinal reactions caused by canagliflozin is low, especially under the dose of 50 mg. Licogliflozin and ertugliflozin have greater possibility to cause gastrointestinal reactions, especially when they were used at high doses.

Domestic and foreign literatures related to the persistence of SARS-CoV-2 and the re-positive cases infected with SARS-CoV-2 were reviewed, and the characteristics and infectivity of the re-positive cases were analyzed to provide scientific evidence for the improvement of case management and the development of measures to stop the spread of SARS-CoV-2. Existing studies have shown that re-positive rate of SARS-CoV-2 ranged from 2.4% to 19.8%, the median of interval between re-positive detection and discharge was 4-15 days. Following the second course of the disease, the anti-SARS-CoV-2 IgM, IgG and IgA positive rates of the cases were 11.11%-86.08%, 52.00%-100.00% and 61.54%-100.00% respectively, the total antibody and neutralizing antibody positive rates were 98.72% and 88.46%. The viral load of the re-positive cases was lower than that in the initial infection. At least 3 380 re-positive cases have been reported globally. SARS-CoV-2 strains were isolated from the samples of 3 re-positive cases (1 immunodeficiency case and 2 cases with abnormal pulmonary imaging). There were close contacts that were infected by an asymptomatic case taking immunosuppressive agents. In conclusion, the infectivity of re-positive cases infected with SARS-CoV-2 is generally very low. Rare re-positive cases infected with SARS-CoV-2 might cause further transmission. The management approach for the re-positive cases can be based on the assessment of the individual transmission risk according to the pathogen detection results.

Objective:To study the epidemic status of drinking tea type endemic fluorosis in Qinghai Province.Methods:In 2019, in counties (cities, districts, referred to as counties) that had the habit of drinking brick tea in 8 cities (prefectures) of Qinghai Province, epidemiological investigation of drinking tea type endemic fluorosis was carried out in villages. Ten households were randomly selected from each village, to investigate the demographic data of each household and the drinking situation of brick tea, residents' drinking water and brick tea samples were collected to determine the fluorine content, and calculate the daily per capita tea fluorine intake. At the same time, skeletal fluorosis was examined in all adults over 25 years old, and dental fluorosis was examined in all children aged 8 to 12 years old in survey sites. The content of fluorine in tea and water was detected by ion selective electrode method; the diagnosis of skeletal fluorosis was based on "Diagnostic Criteria for Endemic Skeletal Fluorosis" (WS 192-2008), the diagnosis of dental fluorosis was based on "Diagnosis of Dental Fluorosis" (WS/T 208-2011).Results:The mean (range) of fluorine of the 3 602 water samples was 0.31 (0.20 - 1.00) mg/L. The geometric mean (range) of fluorine of the 31 067 brick tea samples was 646 (40 - 2 295) mg/kg, the fluorine content of the brick tea ≤300 mg/kg accounted for 7.80% (2 422/31 067) of the total samples. The proportion of drinking Fu brick-tea was 89.97% (27 952/31 067); and the daily per capita tea fluorine intake was 1.93 mg, the daily per capita tea fluorine intake in Guoluo, Yushu and Hainan prefectures were higher than the health standard (3.50 mg). The detection rate of skeletal fluorosis in adults was 0.16% (2 357/1 484 907), Yushu Prefecture was the highest [29.23% (592/2 025)], followed by Guoluo Prefecture, which was 8.21% (771/9 393). The detection rate of dental fluorosis in children was 4.79% (8 076/168 623), Yushu Prefecture was the highest [32.61% (1 562/4 790)].Conclusion:Drinking tea type endemic fluorosis is prevalent in Qinghai Province, with obvious regional characteristics, covering a large population. The disease is relatively popular in Yushu Prefecture and Guoluo Prefecture.
