Abstract
BACKGROUND Pivotal phase III studies demonstrated that abrocitinib, an oral, once-daily, JAK1-selective inhibitor, is effective treatment for moderate-to-severe atopic dermatitis (AD) as monotherapy and in combination with topical therapy. OBJECTIVE The aim of this study was to evaluate the long-term safety of abrocitinib 200 mg and 100 mg in an integrated analysis of a phase IIb study, four phase III studies, and one long-term extension study. METHODS Two cohorts were analyzed: a placebo-controlled cohort from 12- to 16-week studies and an all-abrocitinib cohort including patients who received one or more abrocitinib doses. Adverse events (AEs) of interest and laboratory data are reported. RESULTS Total exposure in the all-abrocitinib cohort (n = 2856) was 1614 patient-years (PY); exposure was ≥ 24 weeks in 1248 patients and ≥ 48 weeks in 606 (maximum 108 weeks). In the placebo-controlled cohort (n = 1540), dose-related AEs (200 mg, 100 mg, placebo) were nausea (14.6%, 6.1%, 2.0%), headache (7.8%, 5.9%, 3.5%), and acne (4.7%, 1.6%, 0%). Platelet count was reduced transiently in a dose-dependent manner; 2/2718 patients (200-mg group) had confirmed platelet counts of < 50 × 103/mm3 at week 4. Incidence rates (IRs) were 2.33/100PY and 2.65/100 PY for serious infection, 4.34/100PY and 2.04/100PY for herpes zoster, and 11.83/100PY and 8.73/100PY for herpes simplex in the 200-mg and 100-mg groups, respectively. IRs for nonmelanoma skin cancer, other malignancies, and major adverse cardiovascular events were < 0.5/100PY for both doses. Five venous thromboembolism events occurred (IR 0.30/100PY), all in the 200-mg group. There were three deaths due to gastric carcinoma (diagnosed at day 43), sudden death, and COVID-19. CONCLUSION Abrocitinib, with proper patient and dose selection, has a manageable tolerability and longer-term safety profile appropriate for long-term use in patients with moderate-to-severe AD.

Abstract
BACKGROUND We assessed the impact of water, sanitation, and hygiene (WASH) and infant and young child feeding (IYCF) interventions on enteric infections in the Sanitation Hygiene Infant Nutrition Efficacy (SHINE) trial in rural Zimbabwe. METHODS We tested stool samples collected at 1, 3, 6, and 12 months of age and during diarrhea using quantitative molecular diagnostics for 29 pathogens. We estimated the effects of the WASH, IYCF, and combined WASH + IYCF interventions on individual enteropathogen prevalence and quantity, total numbers of pathogens detected, and incidence of pathogen-attributable diarrhea. RESULTS WASH interventions decreased the number of parasites detected (difference in number compared to non-WASH arms, -0.07 [95% confidence interval, -.14 to -.02]), but had no statistically significant effects on bacteria, viruses, or the prevalence and quantity of individual enteropathogens after accounting for multiple comparisons. IYCF interventions had no significant effects on individual or total enteropathogens. Neither intervention had significant effects on pathogen-attributable diarrhea. CONCLUSIONS The WASH interventions implemented in SHINE (improved pit latrine, hand-washing stations, liquid soap, point-of-use water chlorination, and clean play space) did not prevent enteric infections. Transformative WASH interventions are needed that are more efficacious in interrupting fecal-oral microbial transmission in children living in highly contaminated environments.

Abstract
OBJECTIVE With the aim of conducting a future cluster randomised trial to assess intervention impact on child vaccination coverage, we designed a pilot study to assess feasibility and aid in refining methods for the larger study. TRIAL DESIGN Cluster-randomised design with a 1:1 allocation ratio. METHODS Clusters were 12 villages in rural Uttar Pradesh. All women residing in a selected village who were mothers of a child 0-23 months of age were eligible; participants were chosen at random. Over 4 months, intervention group (IG) villages received: (1) home visits by volunteers; (2) community mobilisation events to promote immunisation. Control group (CG) villages received community mobilisation to promote nutrition. A toll-free number for immunisation was offered to all IG and CG village residents. Primary outcomes were ex-ante criteria for feasibility of the main study related to processes for recruitment and randomisation (50% of villages would agree to participate and accept randomisation; 30 women could be recruited in 70% of villages), and retention of participants (50% of women retained from baseline to endline). Clusters were assigned to IG or CG using a computer-generated randomisation schedule. Neither participants nor those delivering interventions were blinded, but those assessing outcomes were blinded to group assignment. RESULTS All villages contacted agreed to participate and accepted randomisation. 36 women were recruited per village; 432 participants were randomised (IG n=216; CG n=216). No clusters were lost to follow-up. The main analysis included 86% (373/432) of participants, 90% (195/216) from the IG and 82% (178/216) from the CG. CONCLUSIONS Criteria related to feasibility were satisfied, giving us confidence that we can successfully conduct a larger cluster randomised trial. Methodological lessons will inform design of the main study. TRIAL REGISTRATION NUMBER ISRCTN16703097.

Abstract
PURPOSE To compare the effects and side-effects of fondaparinux sodium and low molecular weight heparin in patients with hypercoagulability accompanied with traumatic infection. METHODS Thirty-six patients with post-traumatic infections in our hospital intensive care center were diagnosed with hypercoagulability from February 2012 to February 2013. These patients were randomly divided into 2 groups. In group F (18 patients), the patients were treated with fondaparinux sodium, 2.5 mg, 1/d for 11 d. In group L (18 patients), the patients were treated with low molecular weight heparin, 4100 U, 1/12 h for 11 d. The incidence of deep vein thrombosis, bleeding events and multiple organ dysfunction syndrome (MODS) and mortality of two groups after anticoagulation therapy were analyzed. Fibrinogen, D-dimer level and activity of antithrombin III were measured by the coagulation analyzer. RESULTS The incidence of deep vein thrombosis, MODS incidence and mortality were not significantly different between the two groups. The rate of bleeding evens in group F was lower than group L (p < 0.05). Antithrombin III got an upward trend after anticoagulant therapy, in which it was higher in group F than in group L on the 5th d and 11th d (p<0.05). Fibrinogen levels were gradually increased, and there was no significant difference between two groups (p>0.05). D-dimer was significantly decreased after anticoagulant therapy for 5 d (p<0.01), and there were significant differences between two groups on the 5th d and 7th d (p<0.05). It showed no significant difference on the 11th d (p>0.05). CONCLUSION Fondaparinux sodium and low molecular weight heparin can effectively improve coagulopathy in patients with traumatic infection. Compared with low molecular weight heparin, fondaparinux sodium may reduce the risk of bleeding events in patients with hypercoagulability accompanied by traumatic infection.

Abstract
BACKGROUND Patients with evidence of vascular disease are at increased risk for subsequent vascular events despite effective use of statins to lower the low-density lipoprotein (LDL) cholesterol level. Niacin lowers the LDL cholesterol level and raises the high-density lipoprotein (HDL) cholesterol level, but its clinical efficacy and safety are uncertain. METHODS After a prerandomization run-in phase to standardize the background statin-based LDL cholesterol-lowering therapy and to establish participants' ability to take extended-release niacin without clinically significant adverse effects, we randomly assigned 25,673 adults with vascular disease to receive 2 g of extended-release niacin and 40 mg of laropiprant or a matching placebo daily. The primary outcome was the first major vascular event (nonfatal myocardial infarction, death from coronary causes, stroke, or arterial revascularization). RESULTS During a median follow-up period of 3.9 years, participants who were assigned to extended-release niacin-laropiprant had an LDL cholesterol level that was an average of 10 mg per deciliter (0.25 mmol per liter as measured in the central laboratory) lower and an HDL cholesterol level that was an average of 6 mg per deciliter (0.16 mmol per liter) higher than the levels in those assigned to placebo. Assignment to niacin-laropiprant, as compared with assignment to placebo, had no significant effect on the incidence of major vascular events (13.2% and 13.7% of participants with an event, respectively; rate ratio, 0.96; 95% confidence interval [CI], 0.90 to 1.03; P=0.29). Niacin-laropiprant was associated with an increased incidence of disturbances in diabetes control that were considered to be serious (absolute excess as compared with placebo, 3.7 percentage points; P<0.001) and with an increased incidence of diabetes diagnoses (absolute excess, 1.3 percentage points; P<0.001), as well as increases in serious adverse events associated with the gastrointestinal system (absolute excess, 1.0 percentage point; P<0.001), musculoskeletal system (absolute excess, 0.7 percentage points; P<0.001), skin (absolute excess, 0.3 percentage points; P=0.003), and unexpectedly, infection (absolute excess, 1.4 percentage points; P<0.001) and bleeding (absolute excess, 0.7 percentage points; P<0.001). CONCLUSIONS Among participants with atherosclerotic vascular disease, the addition of extended-release niacin-laropiprant to statin-based LDL cholesterol-lowering therapy did not significantly reduce the risk of major vascular events but did increase the risk of serious adverse events.

Abstract
INTRODUCTION This study served the following three purposes: To evaluate the prophylactic effect against seroma of a single dose of steroid in the mastectomy cavity, to evaluate the thesis that there is a connection between subclinical bacterial colonization and seroma formation and to evaluate if a simple urine stix test can detect postmastectomy infection. MATERIAL AND METHODS This was a double-blinded and randomized study of injection of methylprednisolonacetate versus saline in the mastectomy cavity at the time of drain removal. A total of 160 females were enrolled after mastectomy. The study parameters were as follows: seroma volume, number of seroma punctures, frequency of clinical infections, degree and type of subclinical colonization, complications and evaluation of the microbiological results of the stix test with automatically read glucose, ketones, blood, pH, protein, nitrite and leucocytes. The degree of inflammation was monitored by measurement of 15 cytokines in each sample of seroma fluid. The study was initiated in August 2010 and is expected to run for three years. DISCUSSION Some reports have concluded that seroma formation forms part of postsurgical inflammation. Steroids are effective against inflammation and accumulation of fluid at the surgical site after several types of surgery and have also proved valuable in the treatment of seroma formation. In the present study, the prophylactic effect of steroids on seroma formation is investigated. CONCLUSION As the incidence of postmastectomy seroma formation is 80%, there is a need for improvement in the prophylaxis and treatment of this condition. FUNDING not relevant. TRIAL REGISTRATION Medicines Agency The EudraCT number 2009-016650-40 has been issued for your Sponsor's Protocol Code Number 23837. Data protection agency J.no. F.750.75-2.

Abstract
BACKGROUND & AIM: The addition of prebiotics to infant formula modifies the composition of intestinal microflora. Aim of the study was to test the hypothesis that prebiotics reduce the incidence of intestinal and respiratory infections in healthy infants. METHODS A prospective, randomized, placebo-controlled, open trial was performed. Healthy infants were enrolled and randomized to a formula additioned with a mixture of galacto- and fructo-oligosaccharides or to a control formula. The incidence of intestinal and respiratory tract infections and the anthropometric measures were monitored for 12 months. RESULTS Three hundred and forty two infants (mean age 53.7+/-32.1 days) were enrolled. The incidence of gastroenteritis was lower in the supplemented group than in the controls (0.12+/-0.04 vs. 0.29+/-0.05 episodes/child/12 months; p=0.015). The number of children with more than 3 episodes tended to be lower in prebiotic group (17/60 vs. 29/65; p=0.06). The number of children with multiple antibiotic courses/year was lower in children receiving prebiotics (24/60 vs. 43/65; p=0.004). A transient increase in body weight was observed in children on prebiotics compared to controls during the first 6 months of follow-up. CONCLUSIONS Prebiotic administration reduce intestinal and, possibly, respiratory infections in healthy infants during the first year of age.

Abstract
BACKGROUND Zinc deficiency, cell-mediated immune dysfunction, susceptibility to infections, and increased oxidative stress have been observed in elderly subjects (ie, those >55 y old). Zinc is an effective antiinflammatory and antioxidant agent. OBJECTIVES The primary objective was to determine the effect of zinc on the incidence of total infections in healthy elderly subjects. The secondary objective was to determine the effect of zinc on cytokines and oxidative stress markers. DESIGN A randomized, double-blind, placebo-controlled trial of zinc supplementation was conducted in elderly subjects. Fifty healthy subjects of both sexes aged 55-87 y and inclusive of all ethnic groups were recruited for this study from a senior center. The zinc-supplemented group received zinc gluconate (45 mg elemental Zn/d) orally for 12 mo. Incidence of infections during the supplementation period was documented. The generation of inflammatory cytokines, T helper 1 and T helper 2 cytokines, and oxidative stress markers and the plasma concentrations of zinc were measured at baseline and after supplementation. RESULTS Compared with a group of younger adults, at baseline the older subjects had significantly lower plasma zinc, higher ex vivo generation of inflammatory cytokines and interleukin 10, and higher plasma oxidative stress markers and endothelial cell adhesion molecules. The incidence of infections and ex vivo generation of tumor necrosis factor alpha and plasma oxidative stress markers were significantly lower in the zinc-supplemented than in the placebo group. Plasma zinc and phytohemagglutin-induced interleukin 2 mRNA in isolated mononuclear cells were significantly higher in the zinc-supplemented than in the placebo group. CONCLUSIONS After zinc supplementation, the incidence of infections was significantly lower, plasma zinc was significantly higher, and generation of tumor necrosis factor alpha and oxidative stress markers was significantly lower in the zinc-supplemented than in the placebo group.

Abstract
BACKGROUND Use of multivitamin and mineral supplements is common among U.S. adults, yet few well-designed trials have assessed the reputed benefits. OBJECTIVE To determine the effect of a daily multivitamin and mineral supplement on infection and well-being. DESIGN Randomized, double-blind, placebo-controlled trial. SETTING Primary care clinics at two medical centers in North Carolina. PARTICIPANTS 130 community-dwelling adults stratified by age (45 to 64 years or >or=65 years) and presence of type 2 diabetes mellitus. INTERVENTION Multivitamin and mineral supplement or placebo taken daily for 1 year. MEASUREMENTS Incidence of participant-reported symptoms of infection, incidence of infection-associated absenteeism, and scores on the physical and mental health subscales of the Medical Outcomes Study 12-Item Short Form. RESULTS More participants receiving placebo reported an infectious illness over the study year than did participants receiving multivitamin and mineral supplements (73% vs. 43%; P < 0.001). Infection-related absenteeism was also higher in the placebo group than in the treatment group (57% vs. 21%; P < 0.001). Participants with type 2 diabetes mellitus (n = 51) accounted for this finding. Among diabetic participants receiving placebo, 93% reported an infection compared with 17% of those receiving supplements (P < 0.001). Medical Outcomes Study 12-Item Short Form scores did not differ between the treatment and placebo groups. CONCLUSIONS A multivitamin and mineral supplement reduced the incidence of participant-reported infection and related absenteeism in a sample of participants with type 2 diabetes mellitus and a high prevalence of subclinical micronutrient deficiency. A larger clinical trial is needed to determine whether these findings can be replicated not only in diabetic persons but also in any population with a high rate of suboptimal nutrition or potential underlying disease impairment.
