BACKGROUND: The use of complementary and alternative medicine (CAM) is common among individuals with underlying chronic illnesses. OBJECTIVE: This systematic review and meta-analysis investigated the global prevalence and patterns of CAM use among individuals with chronic kidney disease (CKD). SEARCH STRATEGY: PubMed, Embase, and Cumulative Index to Nursing and Allied Health Literature Plus were searched from inception until 26th February 2024. INCLUSION CRITERIA: Original articles reporting the use of at least one type of CAM among individuals aged above 18 years old and at all stages of CKD or undergoing any form of kidney replacement therapy. DATA EXTRACTION AND ANALYSIS: Two independent reviewers performed the literature screening. The data were extracted from the included studies by one reviewer and cross-checked by another. Discrepancies were resolved by discussion and consensus among two reviewers. Primary information included prevalence of CAM use, types of CAM used, reasons for CAM use, factors associated with CAM use, and disclosure to healthcare providers. Meta-analyses were performed to determine the pooled prevalence of CAM use and non-disclosure of CAM using a random effect model. RESULTS: Forty-one studies were included in this systematic review and meta-analysis. The pooled prevalence of CAM use was 43% (95% confidence interval: 34%, 51%), I² = 99.46%. The reasons for CAM use included treatment of underlying comorbidities, complications or symptoms, maintenance of general health, and treatment of CKD. Nutritional approaches were the most common CAM modality, with 412 different herbal and dietary supplements reported; psychological and physical approaches included massage therapy, relaxation techniques, and mind-body practices; and other complementary health approaches such as homeopathy, traditional Chinese medicine, and Ayurvedic medicine were also frequently reported. Factors associated with CAM use included sociodemographic characteristics such as older age, female gender, or higher income; disease or therapy factors such as not having diabetes, relying on hemodialysis, or poor adherence to medication; and patient or internal factors such as positive attitude towards CAM and perceived safety of CAM. About 66% (61%, 72%) of CAM users did not disclose the use of CAM to their healthcare providers. CONCLUSION CAM use is prevalent among individuals with CKD, and healthcare providers should communicate openly and effectively to emphasize the rational use of CAM to avoid potential harm.

BACKGROUND: Associations of acute glycemic complications with season and ambient temperature have been reported in general population with diabetes. However, little is known about the risks of acute glycemic complications in relation to season and ambient temperature in pregnant women, who are likely to be even more vulnerable. This work aimed to investigate the associations of season and ambient temperature with pregnancies complicated with hyperglycemia emergency or severe hypoglycemia. METHODS: Two separate case-control studies were nested within 150,153 pregnancies by women with type 1, type 2, or gestational diabetes between 2009 and 2014 in Taiwan. Hyperglycemia emergency (mainly diabetic ketoacidosis and hyperosmolar hyperglycemic state) and severe hypoglycemia occurred in 77 and 153 diabetic pregnancies (cases), respectively. Ten control pregnancies were randomly selected for each case by matching each case pregnancy on type of diabetes (i.e., T1DM, T2DM, or GDM), maternal age on the date of acute glycemic complication occurrence (i.e., index date), and "length of gestation at risk" (i.e., period between conception and index date). Meteorological parameters were retrieved from 542 meteorological monitoring stations across Taiwan during 2008-2014. Conditional logistic regression analysis with generalized estimation equation was separately performed to estimate the covariate adjusted odds ratios (ORs) of each of the two acute glycemic complications in association with season and ambient temperature within 30 days prior to the index date. RESULTS: Compared to summer, winter season was associated with a significantly elevated risk of severe hypoglycemia with an OR of 1.74 (95% confidence interval (CI) 1.08-2.79). The OR of hyperglycemic emergency was also elevated in winter season at OR of 1.88, but the significance is only marginal (95% CI 0.97-3.64, p = 0.0598). Subgroup analyses further noted that such seasonal variation was also observed in pregnancies with pre-pregnancy type 1 diabetes and gestational diabetes. On the other hand, ambient temperature was not significantly associated with the two acute glycemic complications. CONCLUSIONS A moderately but significantly elevated risk of severe hypoglycemia was found in pregnant women with diabetes during winter season, and such increased risk was more evident in pregnancies with T1DM.

The Singapore Health Services cluster (SingHealth) radiology film archives are a valuable repository of local radiological cases dating back to the 1950s. Some of the cases in the archives are of historical medical interest, i.e. cerebral angiography in the workup of patients with hemiplegia. Other cases are of historical social interest, being conditions seen during earlier stages of Singapore's development, i.e. bound feet. The archives form a unique portal into the development of local radiology as well as the national development of Singapore. A selection from the archives is published in commemoration of the International Day of Radiology in 2020, as well as the 200th anniversary of the Singapore General Hospital in 2021. This pictorial essay comprises gastroenterology, musculoskeletal and obstetrics and gynaecology cases from the archives.
