Nordic Walking Improves Cardiometabolic Parameters,Fitness Performance,and Quality of Life in Older Adults With Type 2 Diabetes

ObjectiveTo assess the effect of Nordic walking (NW) on cardiometabolic health, physical performance, and well-being in sedentary older adults with type 2 diabetes (T2D).MethodsFifteen subjects with T2D (female, 5; male, 10; age, 65 ± 6.2 years [mean ± standard deviation]; body mass index, 27.3 ± 4.9 kg/m² [mean ± standard deviation]) were enrolled in a 6-month NW training program. The fasting glucose and glycosylated hemoglobin levels, lipid profile (total cholesterol, low-density lipoprotein cholesterol, high-density lipoprotein cholesterol, and triglycerides), systolic blood pressure (SBP), and diastolic blood pressures were measured before and after the intervention. Participants’ quality of life (Short-Form Health Survey) and physical fitness (6-minute walking test) were also evaluated.ResultsCompared with baseline, NW significantly improved the fasting glucose level (103.5 ± 18.5 vs 168.7 ± 37.7 mg/dL, P = .01), SBP (121.8 ± 12.2 vs 133 ± 14.4 mm Hg, P = .02), physical fitness (759.88 ± 69 vs 615.5 ± 62.6 m, P < .001), and both mental health (54.5 ± 4.4 vs 45.7 ± 5.6, P < .01) and physical health (49.8 ± 4.7 vs 40.3 ± 5.9, P < .01). The levels of glycosylated hemoglobin (6.15% ± 0.8% vs 6.4% ± 1%, P = .46), total cholesterol (162.2 ± 31.2 vs 175.5 ± 28.8 mg/dL, P = .13), low-density lipoprotein cholesterol (95.2 ± 24.2 vs 106.3 ± 32.3 mg/dL, P = .43), and triglycerides (135.5 ± 60.8 vs 127.6 ± 57.4 mg/dL, P = 0.26) improved without reaching significance.ConclusionNW training improved the glycemic levels, SBP, physical fitness, and perception of quality of life in older adults with T2D. NW represents a suitable complementary strategy to improve the global health status in this population.     

Central obesity as a risk factor for prostatic hyperplasia

Objective: Obesity‐related metabolic diseases may influence prostatic hyperplasia. This study examined the impact of obesity on prostate volume in men without overt obesity‐related metabolic diseases. Research Methods and Procedures: We recruited 146 men over the age of 40 years who did not have overt obesity‐related diseases, such as diabetes, impaired fasting glucose, hypertension, or dyslipidemia. Transrectal ultrasonography was performed on all subjects. The subjects were divided into three groups according to their BMI: normal (18.5 to 22.9 kg/m²), overweight (23 to 24.9 kg/m²), and obese (≥25 kg/m²), and two groups according to their waist circumference: normal waist (≤90 cm) and central obesity (>90 cm). The classification of the subgroups was based on the Asia‐Pacific criteria of obesity. We compared the prostate volume among subgroups and assessed factors related to prostatic hyperplasia. Results: Mean prostate volume was 18.8 ± 5.0, 21.8 ± 7.2, and 21.8 ± 5.6 mL in the normal, overweight, and obese groups, respectively, and was 20.0 ± 5.9 and 23.7 ± 5.3 mL in the normal waist and central obesity group, respectively. Prostate volume was significantly greater in the obese group than in the normal group (P = 0.03) and in the central obesity group compared with the normal waist group (P = 0.002). Prostate volume was positively correlated with BMI and waist circumference after adjustment for age. After adjusting for confounding factors, central obesity was an independent factor affecting prostatic hyperplasia, which was defined as a prostate volume >20 mL (odds ratio = 3.37, p = 0.037). Relative to men with both low BMI (18.5 to 22.9 kg/m²) and normal waist circumference, those with high BMI (≥25 kg/m²) and central obesity were at significantly increased risk of prostatic hyperplasia (odds ratio = 4.88, p = 0.008). However, those with high BMI (≥25 kg/m²) and normal waist circumference were not at significantly increased risk. Discussion: Prostate volume was greater in the obese and central obesity groups than in the normal group after patients with overt obesity‐related metabolic diseases were excluded. Although both BMI and waist circumference were positively correlated with prostate volume, central obesity was the only independent factor affecting prostate hyperplasia. We suggest that central obesity is an important risk factor for prostatic hyperplasia.

摘要 目的：探究磁共振成像（MRI）联合血清前列腺特异抗原（PSA）、上皮钙黏蛋白（sE-cadherin）、早期前列腺癌抗原-2（EPCA-2）诊断前列腺癌的临床价值。方法：选取潍坊市人民医院2020年1月-2021年7月期间经病理证实的50例前列腺癌患者（前列腺组）以及50例前列腺增生患者（前列腺增生组）展开回顾性研究。100例研究对象均完善了MRI检查并测定血清PSA、EPCA-2、sE-cadherin水平,分析两组患者的MRI影像学特征,比较两组患者的PSA、EPCA-2、sE-cadherin水平以及各项检查方法的诊断准确性差异。结果：前列腺癌的MRI影像学特征为病灶主要位于外周带,外周带T2W呈低信号,病变侵及包膜、膀胱及周围组织具有T1加权消失或者不对称,具有信号异常、肌肉增厚的表现,盆腔淋巴结转移具有淋巴结部分融合或增大表现;前列腺增生的MRI影像学特征为边界清晰、包膜完整并且中央带增生、不均匀信号结节;前列腺癌、前列腺增生均存在不同程度的前列腺体积增大。相比于前列腺增生组,前列腺癌组患者的PSA、sE-cadherin、EPCA-2水平明显更高（P<0.05）。MRI、PSA、sE-cadherin、EPCA-2四项联合鉴别前列腺癌、前列腺增生的诊断符合率为96.00%,明显高于四项单独诊断的88.00%、79%、81%、82%（P<0.05）。结论：MRI联合PSA、sE-cadherin、EPCA-2鉴别诊断前列腺癌的准确性较高,具有作为临床前列腺癌早期诊断指导方案的潜力。     

Perfil lipídico en mujeres obesas y no obesas con síndrome de ovarios poliquísticos tratadas con metformina

ObjectiveTo compare lipid and lipoprotein concentrations between obese and non-obese women with a diagnosis of polycystic ovary syndrome (PCOS) treated with metformin for 6 months.MethodsSixty-five women with a diagnosis of PCOS were included. The presence of obesity, serum concentrations of cholesterol, triglycerides, high-density lipoprotein cholesterol (HDL-c) and low-density lipoprotein cholesterol (LDL-c) were recorded before and after 6 months of metformin treatment. The women were divided in two groups of 34 obese women (group A; body mass index >27 kg/m²) and 31 non-obese women (group B; body mass index (<27 kg/m²).ResultsSignificant differences in body mass index, waist-hip ratio, cholesterol, triglycerides, LDL-c and HDL-c were found in group A compared with group B (p<0.05). In obese women, serum triglyceride and LDL-c concentrations were significantly reduced (p<0.05), while serum concentrations of HDL-c were significantly increased (p<0.05) after 6 months of treatment. In non-obese women, none of these lipid profile modifications were considered significant (p=ns).ConclusionMetformin use for 6 months modified triglyceride, LDL-c and HDL-c concentrations compared with initial values in obese women with PCOS while no significant modifications in lipid or lipoprotein concentrations were observed in non-obese women.

Assessing the Relationship Between Serum Ghrelin Levels and Metabolic Parameters and Autoimmunity in Patients with Euthyroid Hashimoto's Thyroiditis

ObjectivesHashimoto’s thyroiditis (HT) may affect metabolic parameters and increase predisposition to obesity. In this study, we aimed to assess the relationships among serum ghrelin concentrations, metabolic parameters, and thyroid autoimmunity in euthyroid HT patients.MethodsThe study included 48 euthyroid HT patients and 41 age- and sex-matched healthy controls. We assessed serum ghrelin, free triiodothyronine (T3), free thyroxine (T4), thyroid-stimulating hormone (TSH), thyroid peroxidase antibody (anti-TPO), thyroglobulin antibody (anti-Tg), fasting blood glucose (FBG), insulin, lipid levels, and homeostasis model assessment insulin resistance (HOMA-IR) in all subjects.ResultsSex distribution, mean age, and body mass index (BMI) were similar in HT patients and controls (female/male, 42/6 vs. 33/8, 46.8 ± 14.7 vs. 45 ± 12.5 years,28.5 ± 6.1 vs. 28.4 ± 4.9 kg/m², respectively; P>.05 for all). The mean waist circumference (WC) of the HT group was significantly higher than that of the control group (100.6 ± 14.6 vs. 93.2 ± 13.2 cm, P = .015). While FBG, low-density lipoprotein cholesterol (LDL-C), and triglyceride levels in the HT group were significantly higher than in the control group, insulin levels and HOMA-IR were similar. Ghrelin levels were lower in HT patients compared to controls (416.9 ± 224.4 and 689.9 ± 191.6 pg/mL, respectively; P<.001). Ghrelin levels were similar in patients with low and high anti-TPO titers. Negative correlations were observed between ghrelin levels and BMI, WC, and anti-TPO levels. Regression analysis revealed that HT was the most important predictor of ghrelin levels.ConclusionEuthyroid HT is associated with a decrease in plasma ghrelin levels. Altered body fat distribution and increased anti-TPO levels do not seem to be directly involved in lower ghrelin levels in euthyroid HT patients.

Increased Atherogenic Low-Density Lipoprotein Cholesterol in Untreated Subclinical Hypothyroidism

ObjectiveTo evaluate the effects of physiologic doses of levothyroxine replacement on the lipoprotein profile in patients with subclinical hypothyroidism (SCH).MethodsIn a prospective, double-blind, placebo- controlled study, we enrolled 120 patients—mostly, but not exclusively, premenopausal women—with SCH. Patients were randomly assigned to either a levothyroxine- treated group (n = 60) or a placebo (control) group (n = 60). Total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), and triglycerides (TG) were measured before and 52 weeks after assignment to either group.ResultsIn the levothyroxine-treated group, the lipoprotein mean values before and after the 52-week study were as follows: TC, 5.05 ± 0.98 mmol/L versus 4.74 ± 0.87 mmol/L (P < .0001); LDL-C, 3.30 ± 0.90 mmol/L versus 2.89 ± 0.59 mmol/L (P < .01); TG, 1.18 ± 0.71 mmol/L versus 0.95 ± 0.53 mmol/L (P < .002); and HDL-C, 1.20 ± 0.33 mmol/L versus 1.19 ± 0.32 mmol/L (P = .29). In the control group, TC, HDL-C, and TG values remained unchanged after 52 weeks in comparison with baseline, but LDL-C mean values increased from 2.79 ± 0.60 mmol/L to 3.11 ± 0.77 mmol/L, a change that was statistically significant (P < .001). At the end of the study, the lipid profile changes between levothyroxine- treated and control groups were compared. Total cholesterol and LDL-C were significantly lower in the levothyroxine-receiving group (P < .029 and P < .0001, respectively) in comparison with the control group. The difference did not reach statistical significance for TG and HDL-C values.ConclusionIn premenopausal women, SCH has a negative effect on the lipoprotein profile and may translate into a sizable cardiovascular risk if left untreated.

目的:探讨非那雄胺联合M受体拮抗剂对前列腺增生合并膀胱过度活动症临床疗效的影响。方法:回顾性研究我院前列腺增生合并膀胱过度活动症的患者60例,随机分为实验组和对照组,每组30例。对照组患者给予M受体拮抗剂,实验组患者在对照组的基础上给予非那雄胺。观察并比较治疗前后两组患者国际前列腺症状评分(IPSS)、膀胱过度活动症评分(OABSS)、残余尿量、最大尿流率、尿急次数以及治疗期间不良反应。结果:与对照组相比,实验组患者IPSS及OABSS较低(P0.05);残余尿量较少,最大尿流率较大,尿急次数较少(P0.05);不良反应发生率较低(P0.05)。结论:非那雄胺联合M受体拮抗剂能够降低前列腺增生合并膀胱过度活动症的不良反应发生率,提高临床疗效,值得在临床上推广应用。     

多囊卵巢综合征患者体重指数、内分泌、代谢指标的相关性分析

目的:探讨多囊卵巢综合征患者的体重指数、内分泌及代谢指标的相互关系。方法:选取2016年10月至2017年7月的收治多囊卵巢综合征患者53例作为研究对象,分别根据BMI、HOMA-IR和睾酮水平进行分组,检测和比较体重指数(BMI)、血生化、胰岛素、C肽及性激素等内分泌和代谢指标。结果:根据BMI水平进行分组,空腹胰岛素、60分钟胰岛素、120分钟胰岛素、空腹C肽、60分钟C肽、120分钟C肽、总胆固醇、甘油三酯、低密度脂蛋白、高密度脂蛋白差异有统计学意义(P0.05);根据HOMA-IR指数进行分组,空腹血糖、60分钟血糖、120分钟血糖、空腹胰岛素、60分钟胰岛素、120分钟胰岛素、空腹C肽、60分钟C肽、120分钟C肽、总胆固醇、甘油三酯、低密度脂蛋白、高密度脂蛋白、黄体生成素、黄体生成素/卵泡刺激素、睾酮和雌二醇差异有统计学意义(P0.05);根据睾酮水平进行分组,BMI、空腹胰岛素、60分钟胰岛素、120分钟胰岛素、HOMA指数、黄体生成素、黄体生成素/卵泡刺激素、睾酮、雌二醇差异有统计学意义(P0.05)。结论:多囊卵巢综合征表现复杂多变,应根据不同的体质指数、内分泌和代谢特点进行对症对因治疗,以提高患者治愈水平和生存质量。
