Swimming is a very popular sport among adolescents in the US. Little is known about the diet of competitive adolescent swimmers in the US but data from other countries indicate several inadequacies, including excessive intake of fat and lower than recommended intake of carbohydrate and several micronutrients that may affect athletic performance and bone accrual. We assessed usual diet, using a food frequency questionnaire and calcium checklist, among 191 adolescent males and females [91 swimmers (mean 13.7, s = 2.5 years) and 100 non-athletes (mean 14.4, s = 2.8 years)]. For both males and females, swimmers and non-athletes generally had similar average intakes of macro- and micro-nutrients, including higher than recommended amounts of total fat (36%) and saturated fat (12%), and inadequate amounts of calcium, vitamin D, and daily servings of fruits, vegetables, grains, and dairy products. This first study of nutritional intake among adolescent swimmers in the US suggests that dietary habits of adolescents who swim competitively may jeopardize optimal athletic performance and place them at risk for future chronic diseases, including osteoporosis.

MicroRNAs as potential diagnostic biomarkers for bipolar disorder

引用

Neural Regeneration Research 2025年第6期20卷 1681-1695页

Abnormal expression of microRNAs is connected to brain development and disease and could provide novel biomarkers for the diagnosis and prognosis of bipolar disorder. We performed a PubMed search for microRNA biomarkers in bipolar disorder and found 18 original research articles on studies performed with human patients and published from January 2011 to June 2023. These studies included microRNA profiling in bloodand brain-based materials. From the studies that had validated the preliminary findings,potential candidate biomarkers for bipolar disorder in adults could be miR-140-3p,-30d-5p,-330-5p,-378a-5p,-21-3p,-330-3p,-345-5p in whole blood, miR-19b-3p,-1180-3p,-125a-5p, let-7e-5p in blood plasma, and miR-7-5p,-23b-5p,-142-3p,-221-5p,-370-3p in the blood serum. Two of the studies had investigated the changes in microRNA expression of patients with bipolar disorder receiving treatment. One showed a significant increase in plasma miR-134 compared to baseline after 4 weeks of treatment which included typical antipsychotics, atypical antipsychotics, and benzodiazepines. The other study had assessed the effects of prescribed medications which included neurotransmitter receptorsite binders(drug class B) and sedatives, hypnotics, anticonvulsants, and analgesics(drug class C) on microRNA results. The combined effects of the two drug classes increased the significance of the results for miR-219 and-29c with miR-30e-3p and-526b* acquiring significance. MicroRNAs were tested to see if they could serve as biomarkers of bipolar disorder at different clinical states of mania, depression, and euthymia. One study showed that upregulation in whole blood of miR-9-5p,-29a-3p,-106a-5p,-106b-5p,-107,-125a-3p,-125b-5p and of miR-107,-125a-3p occurred in manic and euthymic patients compared to controls, respectively, and that upregulation of miR-106a-5p,-107 was found for manic compared to euthymic patients. In two other studies using blood plasma,downregulation of miR-134 was observed i

Marriage-Age and Fertility Pattern among Reproductive Age Women in Abakaliki, Ebonyi State, South East Nigeria

引用

Open Journal of Obstetrics and Gynecology 2024年第9期14卷 1449-1462页

作者： Johnson Akuma Obuna Nkiruka bridget Uche-Nwidagu Department of Obstetrics and Gynaecology Ebonyi State University Abakaliki Nigeria National Obstetric Fistula Centre Abakaliki Nigeria

Introduction: In Nigeria, one of the major reasons for marriage is procreation and married couples look forward to having children within a year or two of marriage. The age of marriage is on the increase in this part of the world. Many women are now increasingly getting engulfed in career and academic pursuits at the detriment of early marriage. Many men are also not interested in marrying women who have no job. There is age-related acceleration of primordial follicle depletion which is of great clinical importance because it is associated with a significant decrease in fecundity. Objective: This study assessed the ages of the marriage of women who attended Fertility and Antenatal clinics at the National Obstetric Fistula Centre and Smile Specialist Hospital, Abakaliki, and their relationship with the fertility pattern of these women. Methods: This was a cross-sectional study of 352 consenting married women who sought and received fertility and Antenatal care at the National Obstetric Fistula Centre and Smile Specialist Hospital Abakaliki, South-East Nigeria between February 1, 2022 and January 31, 2024. Semi-structured questionnaires were administered to the participants over a two-year period. Data was analyzed using IBM SPSS version 20. A test of statistical significance was done using Chi Square. Results: The age group with the highest education was 26 - 30. This was statistically significant (X2 = 90.893, P-value 2 = 294.555, P-value 2 = 173.007, p-value 2 = 129.494, P-value 2 = 169.300, p-value 2 = 279.230, p-value Conclusion: There is increased difficulty at conception at marriage age above 25 years. The major reasons for delayed marriage were academic pursuit and lack of gainful employment. Education of the masses and inclusion of biological dynamics of the female reproductive behaviours as part of the core school curriculum will help enlighten the female and the male folks alike to enable them to make informed decisions with regard to the timing of marriage

以某废弃铜冶炼厂收集的铜冶炼烟尘作为样本,采用TCLP毒性浸出和宽溶液pH(3~13)范围浸出实验,研究了铜冶炼烟尘中重金属的释放行为及其矿物学控制机制。结果表明,TCLP浸出液中As、Cd、Cu、Pb和Zn浓度分别是我国《危险废物鉴别标准浸出毒性鉴别》(GB 5085.3—2007)中相应元素限值的704倍、82.7倍、2.08倍、3.1倍和3.26倍。在整个溶液pH处理范围内,As的释放率高达26.0%~28.1%。在酸性条件下Cd、Cu和Zn的浸出率明显较高,而Pb在pH 13.0时释放率较高。地球化学分析表明,在pH 5.5~11.5的溶液处理下,As的溶解度部分受新形成的Ca、Cu、Pb和Zn砷酸盐控制,而Cd、Cu、Pb和Zn的溶解度主要受碱性条件下氢氧化物沉淀形成控制。BCR顺序提取和XRD分析表明,浸出液中Cd和Zn浓度较高与其在灰尘中赋存活性态比例高一致。研究结果为烟尘处理或处置防止重金属污染提供科学指导。
