The recent addition to this growing knowledge in health behavior research is the multi-theory model (MTM) which addresses two crucial modules of health behavior: initiation and sustenance. In spite of reinforcing the habit of brushing twice daily, a lack of sustenance is found among young adults; hence, the objectives were to explore the substratal structure of MTM and to test the fit of MTM questionnaire in dental and medical students in India. Methodology: A questionnaire aimed at addressing sociodemographic information and MTM was designed. Reliability analysis was performed and explorative analysis was done using principal component analysis as the factor extraction method. Construct validity was investigated using exploratory factor analysis (EFA) to add a level of statistical. Results: Reliability analysis revealed a Cronbach's alpha value of 0.892 and split-half reliability value of 0.779. Test–retest reliability was found to be 0.77 (P < 0.01). Guttman split-half reliability was found to be 0.677. EFA suggested seven domains. Indices for model fit showed good fit with P < 0.01. Conclusion: The present study concludes that the Indian version of MTM is a reliable and valid instrument for measuring the initiation and sustenance of toothbrushing behavior in dental and medical students in India.","PeriodicalId":16373,"journal":{"name":"Journal of Natural Science, Biology, and Medicine","volume":"34 1","pages":"149 - 154"},"PeriodicalIF":0.0,"publicationDate":"2021-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82050103","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}

Anatomically, atresia ani has been classified into four types, namely, I, II, III, and IV (Vianna and Tobias, 2005). Type I atresia ani is defined as a congenital stenosis of a patent anus. Type II has a persistent complete anal membrane alone or a combination of an anal membrane with the rectum ending as a blind pouch cranial to the membrane. Type III has an imperforate anus with rectum terminating further cranially. Type IV has a normal ending of the terminal rectum and anus, while the cranial rectum terminates as a blind pouch within the pelvis. Aim of the Study: The aim of the study was to compare the use of customized stent-based correction over the routine pattern followed for the correction of atresia ani et recti. Materials and Methods: Two 3 days old calves with atresia ani et recti were subjects for the study. Both cases were surgically corrected by routine standard surgical technique. Furthermore, in second case, a customized stent was used to prevent stricture of anoplasty. Results: Customized stent used here was successful in preventing the anoplasty stricture as well as this prevented soiling the suture site with feces, which is very common after anoplasty procedure. Conclusion: This case report suggests that use of a sterile syringe, which can be customized, may be used as a stent to prevent stricture of anoplasty as well as reduce wound contamination, thus providing better and faster wound healing and reduces the postoperative complications.","PeriodicalId":16373,"journal":{"name":"Journal of Natural Science, Biology, and Medicine","volume":"705 1","pages":"249 - 251"},"PeriodicalIF":0.0,"publicationDate":"2021-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78708903","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}

Aim: The aim of the present study is to compare preoperative and postoperative serum albumin levels, urine albumin–creatinine ratio (UACR), and estimated glomerular filtration rate (eGFR) in patients undergoing cardiac surgery as a predictor of AKI. Settings and Design: The prospective study was conducted at cardiothoracic unit in the individuals of age 40–70 years admitted for coronary artery bypass grafting. Materials and Methods: The study participants admitted for cardiac surgery with normal serum creatinine value of 0.3–1.3 mg/dl were included. Preoperative and postoperatively (days 1 and 3 after cardiac surgery) parameters such as serum albumin, creatinine, and UACR were analyzed. Baseline serum creatinine >1.6 mg/dl was excluded. eGFR was calculated with Cockcroft's formula and categorized as Group A with eGFR <60 ml/min and Group B with eGFR ≥60 ml/min. Results: Mean UACR compared to baseline was found to be increased progressively on day 1 and day 3 postoperative period after cardiac surgery. Compared with baseline data, albumin levels were found to be decreased during postoperative phase. eGFR reflected the risk of kidney damage as it gets decreased by 15% on day 1 after cardiac surgery. Receiver operating characteristic curve analysis of albumin and UACR revealed sensitivity and specificity that predicts lowered eGFR. Conclusion: Decreased serum albumin and increased UACR after cardiac surgery reflected with lowered eGFR indicate the renal injury after cardiac surgery. Serum hypoalbuminemia and UACR are predictors of AKI in the postoperative phase.","PeriodicalId":16373,"journal":{"name":"Journal of Natural Science, Biology, and Medicine","volume":"1 1","pages":"237 - 241"},"PeriodicalIF":0.0,"publicationDate":"2021-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82952787","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}

Research design and Methods: This prospective open-label randomized interventional study was conducted among newly diagnosed prediabetes in selected districts of Kerala and Tamil Nadu in South India. Participants were randomized to six treatment groups: Group 1 – walking exercise, Group 2 – muscle-specific exercise (ME), Group 3 – metformin intervention, Group 4 – metformin with muscle-specific exercise, Group 5 – antioxidant intervention, and Group 6 – antioxidants with muscle-specific exercise. Drug intervention was for 12 weeks, and the study parameters of the subjects were measured at predefined intervals. The main outcome measures were homeostasis model assessment (HOMA), glycated hemoglobin (HbA1c), fasting blood sugar (FBS), body mass index (BMI), and waist-to-hip ratio. Results: ME intervention in prediabetes significantly reduced BMI, FBS, HbA1c, and HOMA levels (P < 0.05) during the study period. There was also a significant reduction in waist-to-hip ratio among participants taking low-dose metformin along with muscle-specific exercises. Environmental mobility barriers such as weather, traffic, pollution, social support, and even female gender created obstacles in the walking group that led to nonadherence and no significant results in the walking group compared to other groups. Conclusions: Results showed that muscle-specific indoor exercises can be an effective strategy in early management of insulin resistance with better exercise adherence compared to existing interventions. The Implementation of Prediabetes Education Program increased awareness and self-management skills among the prediabetes population.","PeriodicalId":16373,"journal":{"name":"Journal of Natural Science, Biology, and Medicine","volume":"7 1","pages":"230 - 236"},"PeriodicalIF":0.0,"publicationDate":"2021-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74487675","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}

Hence, physiological concentration of Vitamin D is essential for optimal bone health. The optimal concentration of Vitamin D can be maintained by exposing the skin to adequate amount of sunlight or by taking Vitamin D supplement. However, in regions devoid of adequate sunlight, taking Vitamin D supplement is the only option. Unfortunately, the risk– benefit analysis of Vitamin D supplement is still unclear. While some studies have reported the benefits of Vitamin D supplementation, many others have contradicted this claim. A few studies have also reported harmful effects from excessive Vitamin D supplementation. Despite this lack of clarity, the Vitamin D supplement market is projected to be worth Euro 1.5 billion by 2025 with a compound annual growth rate of 12.5%. The strong growth projected in the Vitamin D market is attributed to increasing prevalence of Vitamin D deficiency globally, including geographical regions with adequate sunshine. While the reasons for the increased prevalence of Vitamin D deficiency are not clear, the association of Vitamin D deficiency has been reported with disease conditions beyond bone health. Such an association of Vitamin D deficiency with several disease conditions is not surprising, considering its influence on calcium dynamics, as there is hardly any physiological event which is independent of calcium involvement. Several recent studies have associated Vitamin D deficiency with vascular inflammation and endothelial dysfunction, which remain a hallmark of several disease pathophysiology including cardiovascular diseases. Vitamin D by increasing the activity of sphingomyelinases enhances the clearance of low‐density lipoprotein (LDL) and very LDL and hence reduces inflammation and macrophage adherence, potentially reducing cardiovascular disease risk. Vitamin D is also reported to improve vascular health in chronic kidney disease patients by upregulating thrombomodulin levels. Indeed, the role of Vitamin D as a vascular protective factor is promising and should be further explored. Included in this issue is a study reporting the association of Vitamin D deficiency with inflammatory marker such as high sensitivity C‐reactive protein and disease duration in a cohort of patients with diabetes. Based on its results, the study recommends regular screening of patients with diabetes for their Vitamin D levels as a potential risk analysis of their vascular health. While the evidence for Vitamin D deficiency is valid and reliable, the question remains in the interim, should we overcome Vitamin D deficiency naturally by exposing to sunlight or take the supplements?","PeriodicalId":16373,"journal":{"name":"Journal of Natural Science, Biology, and Medicine","volume":"26 1","pages":"129 - 130"},"PeriodicalIF":0.0,"publicationDate":"2021-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73498028","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}

Hence, monitoring the levels of metal ions in the serum of postoperative patients with metal implants is mandated. Materials and Methods: Blood samples from seventy patients with orthopedic metal implants was collected after a minimum postoperative period of 1 year. The samples were subjected to triple acid digestion and serum levels of chromium and nickel were analyzed using inductively coupled plasma-mass spectrometry. Results: The concentration of chromium (0.13 ± 0.06 μg/L) and nickel (0.39 ± 0.28 μg/L) in serum was within the reference range (chromium: 0.05–0.15 μg/L; nickel: 0.05–1.0 μg/L). Although a relatively high variability in the concentration of nickel was observed compared to chromium. In a subgroup analysis, the concentrations of both metal ions were not influenced by either gender, age groups, site of intramedullary nail, or postoperative duration. Conclusion: The concentration of chromium and nickel in serum of patients with orthopedic metal implants was within the normal reference levels at over 1-year post implant. The concentration of these metal ions was not influenced by gender, age groups, site of intramedullary nail, or postoperative duration.","PeriodicalId":16373,"journal":{"name":"Journal of Natural Science, Biology, and Medicine","volume":"115 1","pages":"189 - 192"},"PeriodicalIF":0.0,"publicationDate":"2021-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73126587","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}

Fasting lipid profile, including triglyceride (TG) and high-density lipoprotein (HDL) cholesterol routinely feature in the outpatient investigation list. Utility of TG/HDL ratio as a surrogate marker for IR was thus studied in healthy young males. Materials and Methods: This cross-sectional study involved 71 young males aged 18–35 years who came for a routine health check in a fasting state. Height, weight, waist circumference were recorded. Fasting plasma glucose (FPG) and lipid profile reports were collected from the laboratory database. Fasting insulin (FI) was estimated by enzyme-linked immunosorbent assay. Body mass index (kg/m2), TG/HDL, TC/HDL, and HOMA-IR2 were calculated. Results: Mean TG/HDL ratio was 3.73 ± 2.03 and HOMA IR2 was above the standard cut off of ≥2.5 units. Subjects were further divided into two groups based on FPG values. TG, low-density lipoprotein, total cholesterol, TG/HDL, TC/HDL, FI and HOMA-IR2 were found to be higher in the pre-diabetes with impaired fasting glycemic subjects. Overall, a statistically significant positive correlation was seen (P = 0.01, r = 0.284) between TG/HDL and HOMA-IR2. Conclusion: TG/HDL ratio was significantly associated with IR and it could be used as an indicator of IR especially in prediabetic subjects having impaired fasting glucose.","PeriodicalId":16373,"journal":{"name":"Journal of Natural Science, Biology, and Medicine","volume":"4 1","pages":"213 - 217"},"PeriodicalIF":0.0,"publicationDate":"2021-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86574098","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}
