This cohort discussed the effect of the number of dissected LNs on the prognosis [survival, disease-free survival (DFS)] of patients with stage II and III CRC.\u0000Methods: In this historical prospective cohort study, the records of 946 patients with CRC operated in the Seyyed-Al-Shohada hospital in Isfahan from 1998 to 2014 were enrolled. Then the impact of LNs on the overall survival (OS) and DFS were analyzed.\u0000Results: The number of removed LNs was higher among males [mean difference = 1.38, t (944) = 2.232, P-value = 0.02]. The median of the DFS for the patients with 1 to 20 LN removal was 104 months [95% confidence interval (CI): 90.97–117.03], while this number for the patients with more than 20 nodes was 166 months (95% CI: 140.41–191.58).

This study aimed to evaluate the inflammatory status, and also examine the impact of NLR on renal outcomes (mortality and composite endpoints) in non-dialysis chronic kidney disease (CKD) patients.\u0000Methods: This prospective cohort was conducted at a tertiary care public teaching hospital. The NLR greater than 3.53 was taken as an indication of systemic inflammation. The outcome measures include composite endpoints (end-stage renal disease, dialysis commencement, doubling serum creatinine from the baseline), and mortality. Kaplan-Meier plots and a multivariate Cox proportional hazard model were employed to analyze the outcomes.\u0000Results: A cohort of 360 patients aged 53.7 years ± 13.9 years had a median follow-up of 14 months ± 4.24 months and was evaluated for inflammatory status and renal outcomes. The proportion of inflammation was found to be 101 (28.7%). Higher NLR levels had shown an increased incidence of mortality (5.3%) and composite endpoints (12.3%). In reference to the NLR quartile (Q1), the highest quartile (Q4) had shown 3 times increased hazards for mortality and 95.0% increased risk of hazards for composite endpoints Q4 hazard ratio (HR) 3.09; 95% confidence interval (CI) 1.38–6.91 (P = 0.006), and Q4 HR 1.93; 95% CI 1.22–3.08 (P = 0.005), respectively.

It is associated with low-grade chronic inflammation, insulin resistance, and metabolic syndrome. Studies have shown ceruloplasmin (Cp) as an independent risk factor for metabolic syndrome and magnesium (Mg), which is required for proper glucose utilization. This study aimed to compare the serum Mg and Cp in PCOS and healthy women and correlate their levels with changes in biochemical, hormonal, and gynaecological aspects of PCOS.\u0000Methods: The study comprised 98 women diagnosed with PCOS using the Rotterdam criteria and 75 age-matched healthy control subjects. The level of serum Cp and Mg were determined using Somani Ambade colorimetric method and methylthymol blue method respectively.\u0000Results: Serum Cp was higher and Mg levels were lower significantly in PCOS patients in comparison with controls. Mg was inversely correlated with fasting blood glucose and directly correlated with follicle-stimulating hormone (FSH). Cp was inversely correlated with prolactin and thyroid-stimulating hormone. Multiple regression analysis revealed that Cp correlates with both the level of luteinizing hormone (LH) and LH/FSH ratio, whereas serum Mg did not have a significant correlation with any of the clinical variables. Logistic regression analysis revealed elevated Cp, antral follicle count (AFC), body mass index (BMI), weight, and irregular menses increase the risk of developing PCOS, whereas Mg was not a risk factor. However, high LH and LH/FSH ratios were risk factors for hypomagnesemia. In conclusion, serum Cp levels in PCOS may be evaluated as an additional risk factor in association with AFC, BMI, weight, and irregular menses.\u0000Conclusions: Mg deficiency and high Cp play an important etiological role in PCOS pathogenesis. Thus, research evaluating dietary interventions and supplementation is warranted.","PeriodicalId":72999,"journal":{"name":"Exploration of medicine","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-04-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46671097","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The surveys applied an online previous-day recall questionnaire on food intake and physical/sedentary activities. Outcome measures were overweight/obesity, whereas exposure variables were daily frequencies of consuming sugary drinks and ultra-processed foods, the total number of dietary items consumed and the total number of sedentary activities per day, and consuming breakfast, mid-morning snacks, lunch, afternoon snack, dinner, and evening snack. Control variables included child age, sex, family income, school shift, survey year, day of the week the questionnaire refers to, metabolic equivalents (METs) of physical activities (PAs), and the quality of dietary and PA reports. Causal effects were estimated by augmented inverse probability weighting.\u0000Results: Daily consumption of sugary drinks, eating ten or more foods, and engaging in three or more sedentary behaviors per day significantly increased the odds ratios (ORs) of being overweight/obese in the range of 3–24% compared to the reference, with 95% confidence intervals in the range of 1–32%. Among 19 ORs with P-value ≤ 0.05, only 3 exceeded 10%.\u0000Conclusions: Under certain conditions, not uncommon in large-scale monitoring and surveillance studies, it is possible to evaluate the causal effects of diet and sedentary activities on overweight/obesity. Daily consumption of sugar-sweetened beverages, eating ten or more foods, skipping breakfast, and engaging in three or more sedentary behaviors per day significantly increased the odds of being overweight/obese.","PeriodicalId":72999,"journal":{"name":"Exploration of medicine","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-04-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47838412","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This research sought to explore associations of acute and sustained use of legal market edible cannabis products on pain, cognition, and quality of life in a group of cancer patients.\u0000Methods: In this observational study, cancer patients completed a baseline appointment, a two-week ad libitum cannabis use period, and an acute administration appointment that included assessments before cannabis use, one-hour post-use, and two-hour post-use. Participants completed self-report questionnaires related to the primary outcomes and the Stroop task as a measure of objective cognitive function.\u0000Results: Twenty-five participants [mean (standard deviation, SD) age = 54.3 years (15.6); 13 females (52.0%)] completed all study appointments and were included in the analysis. Sustained cannabis use was associated with improvements in pain intensity, pain interference, sleep quality, subjective cognitive function, and reaction times in the Stroop task, but no change in general quality of life was observed. High levels of cannabidiol (CBD) use during the two-week ad libitum use period was associated with steeper improvements in pain intensity and sleep quality. Participants reported improvements in pain intensity and increased feelings of subjective high after acute use. High levels of ∆9-tetrahydrocannabinol (THC) use during the acute administration appointment was associated with steeper increases in feelings of subjective high. Improvements in pain were associated with improvements in subjective cognitive function.\u0000Conclusions: This observational study is among the first of its kind to examine associations between legal market, palliative cannabis use, and subjective and objective outcomes among cancer patients.

Craniovertebral angle (CVA) was measured with a digital goniometer to assess head posture: FHP was defined with a CVA < 50° in an upright position. Spirometry was conducted according to European Respiratory Society/American Thoracic Society (ERS/ATS) criteria. Finally, subjects enrolled were evaluated through a self-administered neck disability index (NDI) questionnaire.\u0000Results: Among the 60 participants with agreement about the CVA measurements, 45 had FHP (11 females and 34 males) with lower CVA values.
