Water is indispensable to keeping the functions of the human body working properly, including that of the brain. The purpose of this research was to explore the impacts of water supplementation on cognitive performance and mood, and to determine the optimum amount of water to alleviate detriments of dehydration after 12 h water restriction. A randomized controlled trial was implemented among 64 young adults from Baoding, China. Fasting overnight for 12 h, and at 8:00 a.m. on day 2, osmolality of first morning urine and blood, cognitive performance, and mood were assessed as the dehydration test. Then, participants were randomly separated into four groups: water supplementation groups (WS groups 1, 2, and 3 with 500, 200, and 100 mL purified water, respectively) and no water supplementation group (NW group). Participants in WS groups were instructed to drink the water within 10 min, while those in NW group drank no water. After 90 min, the same measurements were taken as the rehydration test. There was significant interaction between TIME and VOLUME in thirst when comparing dehydration with rehydration tests (F = 6.172, p = 0.001). Significant thirst reductions were found in WS group 1 and WS group 2 (p = 0.003; p = 0.041), and a significant increase was found in the NW group (p = 0.039). In the rehydration test, significant interactions between TIME and VOLUME were found in scores of anger, fatigue, and TMD (total mood disturbance) (F = 3.815, p = 0.014; F = 10.429, p < 0.001; F = 5.246, p < 0.001), compared to the dehydration test. Scores of anger were only decreased in WS group 2 (p = 0.025), and scores of fatigue and TMD decreased in WS group 1 and WS group 2 (all p < 0.05). Significant interaction between TIME and VOLUME was only found for operation span test scores (F = 2.816, p = 0.047), with scores being only higher in WS group 1 in the rehydration test compared to the dehydration test (p = 0.003). Comparing WS group 1 and WS group 2, scores of thirst, fatigue, and TMD did not differ significantly (p > 0.05). Water supplementation improved working memory and attenuated anger, fatigue, and TMD. A small amount of water (200 mL) was sufficient to attenuate thirst, anger, fatigue, and TMD of young adults, but the larger volume (500 mL) appeared to be necessary to improve working memory. The amount of 500 mL was the optimum volume to improve the cognitive performance and mood among young adults.

The brain is approximately 75% water. Therefore, insufficient water intake may affect the cognitive performance of humans. The present study aimed to investigate the effects of water restriction and supplementation on cognitive performances and mood, and the optimum amount of water to alleviate the detrimental effects of dehydration, among young adults. A randomized controlled trial was conducted with 76 young, healthy adults aged 18–23 years old from Baoding, China. After fasting overnight for 12 h, at 8:00 a.m. of day 2, the osmolality of the first morning urine and blood, cognitive performance, and mood were measured as a baseline test. After water restriction for 24 h, at 8:00 a.m. of day 3, the same indexes were measured as a dehydration test. Participants were randomly assigned into four groups: water supplementation group (WS group) 1, 2, or 3 (given 1000, 500, or 200 mL purified water), and the no water supplementation group (NW group). Furthermore, participants were instructed to drink all the water within 10 min. Ninety minutes later, the same measurements were performed as a rehydration test. Compared with the baseline test, participants were all in dehydration and their scores on the portrait memory test, vigor, and self-esteem decreased (34 vs. 27, p < 0.001; 11.8 vs. 9.2, p < 0.001; 7.8 vs. 6.4, p < 0.001). Fatigue and TMD (total mood disturbance) increased (3.6 vs. 4.8, p = 0.004; 95.7 vs. 101.8, p < 0.001) in the dehydration test. Significant interactions between time and volume were found in hydration status, fatigue, vigor, TMD, symbol search test, and operation span test (F = 6.302, p = 0.001; F = 3.118, p = 0.029; F = 2.849, p = 0.043; F = 2.859, p = 0.043; F = 3.463, p = 0.021) when comparing the rehydration and dehydration test. Furthermore, the hydration status was better in WS group 1 compared to WS group 2; the fatigue and TMD scores decreased, and the symbol search test and operation span test scores increased, only in WS group 1 and WS group 2 (p < 0.05). There was no significant difference between them (p > 0.05). Dehydration impaired episodic memory and mood. Water supplementation improved processing speed, working memory, and mood, and 1000 mL was the optimum volume.

Water is a critical nutrient that is important for the maintenance of the physiological function of the human body. This article aimed to investigate the effects of the amount and frequency of fluid intake on cognitive performance and mood. A double-blinded randomized controlled trial was designed and implemented on college students aged 18–23 years in Baoding, China. Participants were randomly assigned into one of three groups: the recommended behavior group (RB group) who drank 200 mL of water every 2 h, the half amount group (HA group) who drank 100 mL of water every 2 h, and the high frequency group (HF group) who drank 110 mL of water every 1 h. The intervention lasted 2 days. Urine osmolality, cognitive performance, and mood of participants in each group were compared using the one-way analysis of variance (ANOVA). A total of 92 participants (46 females, 46 males) completed this study with a completion rate of 95.8%. The urine osmolality of the HA group was higher than that of the RB group and the HF group at two time points (p < 0.05). At time point 1, the scores in the portrait memory test and vigor were statistically different (F = 20.45, p < 0.001; F = 5.46, p = 0.006). It was found that the scores for the portrait memory test in the RB group were lower than those in the HA group and the HF group (p = 0.007; p < 0.001), while the scores of the HF group were higher than those of the HA group (p < 0.001). The scores for vigor in the RB group were significantly higher than those of the HA group (p = 0.006), and they were also significantly higher than those of the HF group (p = 0.004). At time point 2, only the scores for vigor were statistically different (F = 3.80, p = 0.026). It was found that the scores for vigor in the RB group were higher than those in the HA group and HF group (p = 0.018; p = 0.019). Both the amount and frequency of fluid intake may affect urine osmolality and vigor, but these factors have limited impacts on cognitive performance. Rational fluid intake behavior may be beneficial to improve the hydration status and mood of young adults. More research is needed, especially experimental research, to allow causal conclusions to be drawn.

Background: Vitamin D deficiency remains the most common cause of rickets globally and is highly prevalent in developing countries including India. This study aimed to compare the efficacy of vitamin D and calcium together with calcium alone on growth parameters of children with vitamin D deficiency in community based setting.Methods: A randomized controlled trial was conducted in community based setting in Kanpur district. Multistage random sampling technique was used to select a total of 395 children between 2 years to 5 years from 5 villages of block Vidhunu. Of these, 138 children were randomized into two groups using balanced block randomization technique. Group 1 received vitamin D with calcium together and group 2 received calcium alone for a period of 12 months. Anthropometry, serum vitamin D, calcium, alkaline phosphatase levels were estimated at baseline and after 12 months. Data was analyzed using SPSS 20. Student’s t test was used to analyze the differences in growth and laboratory parameters in the two groups. Multiple linear regression analysis was used to assess the effect of various factors on the growth parameters.Results: Prevalence of vitamin D deficiency was 78.7%. Baseline characteristics of both groups were similar. After 12 months, group 1 demonstrated significantly greater improvement in weight SD score (21.4%) and height SD score (10.3%) and growth velocity (9.1 cm/year) compared to group 2 (14.3%, 7.8% and 6.9 cm/ year respectively). Also subjects in group 1 showed significantly greater improvement in serum levels of vitamin D, calcium and alkaline phosphatase than group 2.Conclusions: Vitamin D supplementation along with calcium improves the growth of children. Regular supplementation of all children with vitamin D can be considered as a policy for prevention of malnutrition.

Background: Being a diagnosis of exclusion the treatment options of unexplained infertility are often empiric. There is significant dilemma regarding the superiority of one over another. Despite increasing use of intrauterine insemination (IUI) in adjunct to controlled ovarian hyperstimulation (COH) there is scarcity of randomized controlled trials (RCT) from developing countries. Objective was to compare IUI and timed intercourse (TI) in super ovulated cycles among couples with unexplained infertility over one year.Methods: In this prospective randomized controlled trial total 85 patients were randomly assigned into group 1 (COH with IUI, N= 44) and group 2 (COH with TI, N=41). Patients underwent COH using sequential Clomiphene Citrate and injection human menopausal gonadotrophin followed by IUI in group 1 and timed intercourse in group 2. Either protocol was repeated for three consecutive cycles. Finally, both groups were compared for clinical pregnancy rate, adverse effects and acceptability of the treatment process and outcome. Comparison was done by Student’s unpaired t test for continuous and 2-tailed chi square test for categorical variables.Results: Clinical pregnancy rates following COH/IUI and COH/TI were 13.64% and 19.51% respectively. There was observable difference in the acceptability of the outcome (38.64% in IUI and 56.09% in TI group). All the results including complications and side effect rates were statistically insignificant.Conclusions: Present study failed to show any improvement of pregnancy rates following addition of IUI over TI and it raised the probability that the outcome of the procedure may not be well accepted.

The aim of this study was to determine the efficacy of single versus repetitive injection of lignocaine into the carpal tunnel for the management of carpal tunnel syndrome. The 42 patients included were randomly assigned to two Groups: group 1 was injected with 4 mL of 1% lignocaine once and Group 2 was injected with 4 mL of 1% lignocaine twice a week for 2 weeks. Clinical and electrophysiological evaluations were performed at the study onset, and at 6 and 12 weeks following the final injection. Initially, the groups were similar with respect to clinical and electrophysiological findings. All parameters in Group 2 improved 6 weeks post treatment ( p < 0.05), and these improvements persisted at 12 weeks post treatment ( p < 0.05). Repetitive local lignocaine injection was effective in reducing the symptoms of carpal tunnel syndrome and improving electrophysiological findings.

Aims: This study aims to compare the efficacy in alleviating pain between intracanal medicaments, namely Nitrofurantoin and Calcium Hydroxide Paste. Study Design:  Randomized Controlled Trial. Place and Duration of Study: Sample: Department of Operative Dentistry, Sir Syed College of Medical Sciences, Pakistan, between January 2021 and May 2021. Methodology: 60 patients were randomly divided into 3 groups, each group having 20 patients as following: Group 1: Nitrofurantoin, Group 2: Calcium Hydroxide and Group 3: Control. Preoperative pain was recorded using a numerical pain scale. After access preparation, chemomechanical preparation was performed with subsequent placement of intracanal medicaments. Pre-operative pain score was initially recorded, followed by post-operative pain at 12, 24, 48, and 72 hours, respectively. Root canal treatment was performed in single rooted teeth with patients suffering from symptomatic irreversible pulpitis Results: Majority of the patients in all 3 groups were initially presented with moderate to severe pre-operative pain. After 72 hours post-operatively, 50% patients in Group 1 reported no pain, while 5% patients in both Group 2 and 3 had no pain. Pain significantly subsided in Group 1 as compared to Group 2 and 3. Regarding age and gender, both had no significant relationship with the pain scores in all of the 3 groups Conclusion: Nitrofurantoin has been proven to be an effective intracanal medicament in alleviating immediate post-operative pain in patients with symptomatic irreversible pulpitis as compared to calcium hydroxide. While the control group with no intracanal medicament showed little reduction in pain scores. So, nitrofurantoin can be used as a substitute to currently available standard intracanal medicaments.

Objective: To evaluate the role of intermittent pneumatic compression in the treatment of breast cancer–related lymphoedema. Design: Randomized controlled trial. Setting: Physical medicine and rehabilitation clinic at a university hospital. Subjects: Seventy-six patients with lymphoedema. Interventions: Patients were allocated into Group 1 (complex decongestive treatment, n = 38) and Group 2 (complex decongestive treatment + intermittent pneumatic compression, n = 38). The complex decongestive treatment involved skin care, manual lymphatic drainage, compression bandaging, and exercise for 20 sessions. Group 2 additionally received intermittent pneumatic compression. Main measures: Quantitative outcomes consisted of volumetric measures prior to and after the treatment. Clinical assessments included severity of pain, heaviness and tightness, disability, grip strength, and depression. Results: Lymphoedema was similar at baseline, but treatments significantly reduced the excess volume (from 373 mL to 203 mL in Group 1 and 379.5 mL to 189.5 mL in Group 2). Percentage excess volumes (PEVs) decreased in both groups. The percentage reduction of excess volume was better in Group 2 than Group 1, but the intergroup difference was not significant. The clinical scores reflected improvements, but the heaviness and tightness read significantly lower in Group 2 than Group 1. Conclusion: Intermittent pneumatic compression seems to add no benefit when combined with complex decongestive treatment of lymphoedema, but, may be functional in reducing the sensations of heaviness and tightness for the patients with pitting oedema.

Abstract Background We evaluated whether integration of novel diets for donors and patients in addition to fecal transplantation (FT) could increase FT remission rate in refractory ulcerative colitis (UC). Methods This was a blinded randomized controlled trial in adults with active UC, defined by a simple clinical colitis activity index (SCCAI) of ≥5 and ≤ 11 and endoscopic Mayo score 2-3, refractory to medication. Group 1 received free diet and single donor standard FT by colonoscopy on day 1and rectal enemas on days 2 and 14 without dietary conditioning of the donor. Group 2: FT as above but with dietary pre-conditioning of the donor for 14 days and a UC Exclusion Diet (UCED) for the patients. Group 3 received the UCED alone. The primary endpoint was week 8 clinical steroid free remission, defined as SCCAI &lt;3. Results Sixty two of 96 planned patients were enrolled. Remission week 8 Group 1 was 2/17 (11.8%), Group 2 4/19 (21.1%), Group 3 6/15 (40%) (NS). Endoscopic remission was Group 1 2/17 (12%), Group 2 3/19 (16%), Group 3 4/15 (27%) (Group 1 vs.3 p=0.38). Mucosal healing (Mayo 0) was achieved only in Group 3 (3/15, 20%) vs. 0/36 FT patients (p=0.022). Exacerbation of disease occurred in 3/17 (17.6%) Group 1, 4/19 (21.1%) Group 2, and 1/15 (6.7%) Group 3 (Group 2 vs.3, p=0.35). Conclusions UCED alone appeared to achieve higher clinical remission and mucosal healing than single donor FT with or without diet. The study was stopped for futility by a safety monitoring board.

Aims In total knee arthroplasty (TKA), blood loss continues internally after surgery is complete. Typically, the total loss over 48 postoperative hours can be around 1,300 ml, with most occurring within the first 24 hours. We hypothesize that the full potential of tranexamic acid (TXA) to decrease TKA blood loss has not yet been harnessed because it is rarely used beyond the intraoperative period, and is usually withheld from ‘high-risk’ patients with a history of thromboembolic, cardiovascular, or cerebrovascular disease, a patient group who would benefit greatly from a reduced blood loss. Methods TRAC-24 was a prospective, phase IV, single-centre, open label, parallel group, randomized controlled trial on patients undergoing TKA, including those labelled as high-risk. The primary outcome was indirect calculated blood loss (IBL) at 48 hours. Group 1 received 1 g intravenous (IV) TXA at the time of surgery and an additional 24-hour postoperative oral regime of four 1 g doses, while Group 2 only received the intraoperative dose and Group 3 did not receive any TXA. Results Between July 2016 and July 2018, 552 patients were randomized to either Group 1 (n = 241), Group 2 (n = 243), or Group 3 (n = 68), and 551 were included in the final analysis. The blood loss did differ significantly between the two intervention groups (733.5 ml (SD 384.0) for Group 1 and 859.2 ml (SD 363.6 ml) for Group 2; mean difference -125.8 ml (95% confidence interval -194.0 to -57.5; p < 0.001). No differences in mortality or thromboembolic events were observed in any group. Conclusion These data support the hypothesis that in TKA, a TXA regime consisting of IV 1 g perioperatively and four oral 1 g doses over 24 hours postoperatively significantly reduces blood loss beyond that achieved with a single IV 1 g perioperative dose alone. TXA appears safe in patients with history of thromboembolic, cardiovascular, and cerebrovascular disease. Cite this article: Bone Joint J 2021;103-B(10):1595–1603.
