Background: It has been widely reported that vitamin D (vit D) affects preoperative, postoperative, and long-term outcomes after total knee arthroplasty (TKA). Our aim was to study vit D trajectory after TKA and compare effects of oral versus intramuscular (IM) supplementation in insufficient patients and assess its effects on immediate functional recovery in the first 2 weeks after TKA. Methods: Vit D levels < 30 ng/mL are considered insufficient. We prospectively enrolled 60 patients (20 per group): group I, vit D sufficient patients; group II, vit D insufficient patients given IM supplementation (cholecalciferol 6,00,000 IU); and group III, vit D insufficient patients given oral supplementation (cholecalciferol 600,000 IU). Vit D levels, knee flexion, Timed Up and Go (TUG) test results, and visual analog scale (VAS) score were recorded preoperatively and postoperatively on day 3 and 14. Results: In group I, mean preoperative vit D significantly dropped at postoperative day (POD) 3 and POD 14 (p = 0.001). In group II, mean preoperative vit D rose at POD 3 and rose significantly at POD 14 (p = 0.001). In group III, mean preoperative vit D increased significantly at both POD 3 and POD 14 (p < 0.001). Also, in group III, the rise in vit D was significantly higher than that in group II both at POD 3 and POD 14 (p < 0.05). In group III, 19 of 20 insufficient patients became sufficient on POD 3 and all 20 by POD 14. In group II, even by POD 14, only 11 of 20 insufficient patients became sufficient. Functional parameters (flexion, change in flexion, TUG test results, and VAS score) were comparable (p > 0.05) in all groups. Changes in TUG test showed a significant increase in group II (48.5 seconds) when compared to group I (35.5 seconds) at POD 3 (p < 0.05), suggesting a slower recovery. It remained comparable (p > 0.05) between group III and group I. Conclusions We found that vit D insufficient patients can be rapidly supplemented on the morning of surgery with a large dose of oral cholecalciferol 600,000 IU, and the effect was consistent over 2 weeks after surgery. Orally supplemented vit D insufficient patients also showed functional recovery comparable to vit D sufficient patients. IM supplementation increased vit D levels only at 2 weeks and the rise was significantly lower than oral supplementation. Interestingly, approximately 25% of vit D sufficient patients who were not supplemented after TKA became insufficient in the first 2 weeks postoperatively.

A 60-year-old Indian male with a 2 year history of diabetes mellitus on insulin therapy and a past history of right sided hemiparesis due to cerebrovascular accident (CVA) presented with fracture of the neck of the left femur after a fall. X-ray showed extensive vascular calcifications, scrotal calcification and severe osteoporosis.

Background: Nonhuman primates are used for research purposes such as studying diseases and drug discovery and development programs. Various clinical pathology parameters are used as biomarkers of disease conditions in biomedical research. Detailed reports of these parameters are not available for Indian-origin rhesus macaques. To meet the increasing need for information, we conducted this study on 121 adult Indian rhesus macaques (57 wild-sourced and 64 inhouse animals, aged 3–7 years). A total of 18 hematology and 18 biochemistry parameters were evaluated and reported in this study. Data from these parameters were statistically evaluated for significance amongst inhouse and wild-born animals and for differences amongst sexes. The reference range was calculated according to C28-A3 guidelines for reporting reference intervals of clinical laboratory parameters. Results: Source of the animals and sex appeared to have statistically significant effects on reference values and range. Wild-born animals reported higher WBC, platelets, neutrophils, RBC, hemoglobin, HCT, MCV, and total protein values in comparison to inhouse monkeys. Sex-based differences were observed for parameters such as RBCs, hemoglobin, HCT, creatinine, calcium, phosphorus, albumin, and total protein amongst others. Conclusions Through this study, we have established a comprehensive data set of reference values and intervals for certain hematological and biochemical parameters which will help researchers in planning, conducting, and interpreting various aspects of biomedical research employing Indian-origin rhesus monkeys.

A 25-year-old Indian male presented to Endocrine Outpatient Department of PGIMS Rohtak with chief complaints of inability to father a child in spite of 2 years of unprotected sexual intercourse. Patient had a normal male phenotype, however seminal fluid analysis was suggestive of azoospermia. Karyotyping chromosomal analysis showed 46, XX chromosomes. The frequency, etiology and diagnosis of this syndrome are reviewed here.

Background/Aims: Exclusive enteral nutrition (EEN), an established modality for pediatric Crohn’s disease (CD) is seldomly utilized in adults. The present study reports the outcome of EEN in adult CD patients at a tertiary care hospital in India. Methods: This was a retrospective analysis of CD patients who received EEN as a sole modality/adjunct to other treatment. The primary and secondary outcomes changed in Crohn’s Disease Activity Index (CDAI), and clinical response (decline in CDAI > 70), respectively, at 4 and 8 weeks. Subgroup analysis evaluated response across different phenotypes, EEN formulations and prior treatment. Linear mixed effect model was created to assess the predictors of EEN response. Results: Thirty-one CD patients received EEN over median duration of 4 weeks (range, 2–6 weeks). CDAI showed a significant improvement post EEN at 4 (baseline 290 [260–320] vs. 240 [180–280], P= 0.001) and 8 weeks (baseline 290 [260–320] vs. 186 [160–240], P= 0.001), respectively. The cumulative clinical response rates at 4 and 8 weeks were 37.3% and 80.4% respectively. The clinical response rates at 8 weeks across B1 (n = 4), B2 (n = 18) and B3 (n = 9) phenotypes were 50%, 78.8% and 100% respectively (log-rank test, P= 0.093). The response rates at 8 weeks with polymeric (n = 8) and semi-elemental diet (n = 23) were 75% and 82.6%% respectively (log-rank test, P= 0.49). Baseline CDAI (odds ratio, 1.008; 95% confidence interval, 1.002–1.017; P= 0.046) predicted response to EEN. Conclusions EEN was effective in inducing clinical response across different phenotypes of CD. Baseline disease activity remained the most important predictor of clinical response to EEN.
