BackgroundVitamin C (500 mg·day−1) supplementation for pregnant smokers has been reported to increase newborn pulmonary function and infant forced expiratory flows (FEFs) at 3 months of age. Its effect on airway function through 12 months of age has not been reported.ObjectiveTo assess whether vitamin C supplementation to pregnant smokers is associated with a sustained increased airway function in their infants through 12 months of age.MethodsThis is a pre-specified secondary outcome of a randomised, double-blind, placebo-controlled trial that randomised 251 pregnant smokers between 13 and 23 weeks of gestation: 125 to 500 mg·day−1 vitamin C and 126 to placebo. Smoking cessation counselling was provided. FEFs performed at 3 and 12 months of age were analysed by repeated-measures analysis of covariance.ResultsFEFs were performed in 222 infants at 3 months and 202 infants at 12 months of age. The infants allocated to vitamin C had significantly increased FEFs over the first year of life compared to those allocated to placebo. The overall increased flows were 40.2 mL·s−1 for at FEF75 (75% of forced vital capacity (FVC)) (adjusted 95% CI for difference 6.6–73.8; p=0.025); 58.3 mL·s−1 for FEF50 (10.9–105.8; p=0.0081); and 55.1 mL·s−1 for FEF25–75 (9.7–100.5; p=0.013).ConclusionsIn offspring of pregnant smokers randomised to vitamin C versus placebo, vitamin C during pregnancy was associated with a small but significantly increased airway function at 3 and 12 months of age, suggesting a potential shift to a higher airway function trajectory curve. Continued follow-up is underway.

Abstract Objectives Homeopathic treatment is claimed to be beneficial for primary dysmenorrhoea (PD); still, systematic research evidences remain compromised. This study was undertaken to examine the efficacy of individualized homeopathic medicines (IH) against placebo in the treatment of PD. Methods A double-blind, randomized, placebo-controlled trial was conducted at the gynecology outpatient department of Mahesh Bhattacharyya Homoeopathic Medical College and Hospital, West Bengal, India. Patients were randomized to receive either IH (n=64) or identical-looking placebo (n=64). Primary and secondary outcome measures were 0–10 numeric rating scales (NRS) measuring intensity of pain of dysmenorrhea and verbal multidimensional scoring system (VMSS) respectively; all measured at baseline, and every month, up to 3 months. Group differences and effect sizes (Cohen’s d) were calculated on intention-to-treat (ITT) sample. Results Groups were comparable at baseline (all p>0.05). Attrition rate was 10.9% (IH: 7, placebo: 7). Differences between groups in both pain NRS and VMSS favoured IH over placebo at all time points (all p<0.001, unpaired t-tests and two-ways repeated measures analysis of variance) with medium to large effect sizes. Natrum muriaticum and Pulsatilla nigricans (n=20 each; 15.6%) were the most frequently prescribed medicines. No harms, serious adverse events and intercurrent illnesses were recorded in either of the groups. Conclusions Homeopathic medicines acted significantly better than placebo in the treatment of PD. Independent replication is warranted. Trial registration: CTRI/2018/10/016013.

Pelargonium Sidoides

Abstract Background Pelargonium sidoides DC (Geraniaceae) root extract, EPs®7630 or “Kaloba®”, is a widely used herbal remedy for respiratory infections, with some evidence of effectiveness for acute bronchitis. However, it is not yet widely recommended by medical professionals in the UK. There is a need to undertake appropriately designed randomised trials to test its use as an alternative to antibiotics. The aim was to assess the feasibility of conducting a double-blind randomised controlled trial of Pelargonium sidoides root extract for treatment of acute bronchitis in UK primary care, investigating intervention compliance, patient preference for dosage form and acceptability of patient diaries. Study design Feasibility double-blind randomised placebo-controlled clinical trial. Methods We aimed to recruit 160 patients with cough (≤ 21 days) caused by acute bronchitis from UK general practices. Practices were cluster-randomised to liquid or tablet preparations and patients were individually randomised to Kaloba® or placebo. We followed participants up for 28 days through self-reported patient diaries with telephone support and reviewed medical records at one month. Outcomes included recruitment, withdrawal, safety, reconsultation and symptom diary completion rates. We also assessed treatment adherence, antibiotic prescribing and consumption, mean symptom severity (at days 2–4 after randomisation) and time to symptom resolution. We interviewed 29 patients and 11 health professionals to identify barriers and facilitators to running such a randomised trial. Results Of 543 patients screened, 261 were eligible, of whom 134 (51%) were recruited and 103 (77%) returned a completed diary. Overall, 41% (41/100) of patients took antibiotics (Kaloba® liquid group: 48% [15/31]; placebo liquid group: 23% [6/26]; Kaloba® tablet group: 48% [9/21]; placebo tablet group: 50% [11/22]). Most patients adhered to the study medication (median 19 out of 21 doses taken in week 1, IQR 18–21 - all arms combined). There were no serious adverse events relating to treatment. Most patients interviewed found study recruitment to be straightforward, but some found the diary too complex. Conclusions It was feasible and acceptable to recruit patients from UK primary care to a double-blind placebo-controlled trial of herbal medicine (Kaloba®) for the treatment of acute bronchitis, with good retention and low data attrition. Trial registration HATRIC was registered on the ISRCTN registry (ISRCTN17672884) on 16 August 2018, retrospectively registered. The record can be found at http://www.isrctn.com/ISRCTN17672884.

BACKGROUND: Chronic neck pain (CNP) is a common health problem in western industrialized nations. In recent years, the fascial tissue has attracted the attention of therapists, and a treatment of the fasciae promises to be a meaningful approach in the therapy of patients with CNP. OBJECTIVE: The aim of this study was to investigate the effectiveness of a fascial treatment (FT) compared to manual therapy (MT) and to no intervention (control group, CG) in patients with CNP. METHODS: Sixty participants with CNP were randomized into three groups. Primary outcome parameters were pain intensity as measured by the visual analogue scale (VAS), and severity of illness as measured by the Neck Pain and Disability Scale (NPAD). Secondary outcome parameter was the range of motion (ROM) of the cervical spine. RESULTS: Repeated measures t-tests demonstrated significant decreases with medium to large effect sizes for the FT (VAS: dR⁢M= 1.14; NPAD: dR⁢M= 0.51) and for the MT (VAS: dR⁢M= 1.15; NPAD: dR⁢M= 0.72). CONCLUSION: Our results confirmed the effectiveness of MT on pain and severity of illness in the treatment of patients suffering from CNP. Furthermore, the results demonstrated the effectiveness and clinical relevance of FT for this population.

Abstract Objectives Determine if children (6 to 23 mo) who received daily preventive zinc (PZ; 7 mg/d), daily high-zinc, low-iron micronutrient powder (MNP; 10 mg/d zinc, 6 mg/d iron) or therapeutic zinc during episodes of diarrhea (TZ; 20 mg/d for 10 d per episode) have improved markers of innate and adaptive immune function, compared to placebo (PL). Methods Rural Laotian children were recruited into a double-blind, randomized, controlled intervention trial for 9 mo. Venous blood was collected at baseline (BL) and endline (EL) for analysis. Primary outcomes included T-cell subsets (naïve and memory CD4, CD8, Tregs) measured by flow cytometry and production of T-cell cytokines (IL-2, IL-10, IL-13, IL-17A, INF-γ) and LPS-induced cytokines (IL-1β, IL-6, IL-10, TNF-α by whole blood cultures. Blood leukocytes (including lymphocytes, neutrophils, monocytes and eosinophils) were measured as secondary outcome variables. Group means at EL were compared by analysis of covariance (controlling for BL values of the outcome, sex, child age, district, month of enrollment and plasma zinc concentration). If an interaction with BL plasma zinc (above/below median) was observed, group means were compared separately in children above and below the median. Results Mean BL plasma zinc in all children (N = 574) was 0.55 ± 0.12 mg/L. No significant group differences were seen at EL in the primary outcomes. For secondary outcomes, the counts (^103/μL) of lymphocytes from the PZ group (5.02 ± 0.16) were significantly lower than the PL group (5.64 ± 0.16; P = 0.032). The EL counts (^103/μL) of from the PZ group (0.144 ± 0.026) were significantly lower than in the PL (0.279 ± 0.048; P = 0.036) and TZ (0.285 ± 0.047; P = 0.025) groups among children with baseline zinc below the median. Conclusions Primary outcomes (T-cell subsets, and cytokine production) were not affected by the zinc intervention. Lymphocyte and eosinophil concentrations may be affected by zinc treatment but this result requires confirmation.

ObjectivesMethotrimeprazine is commonly used for the management of nausea but never tested formally against other drugs used in this setting. The aim was to demonstrate superior antiemetic efficacy.DesignDouble-blind, randomised, controlled trial of methotrimeprazine versus haloperidol.Setting11 palliative care sites in Australia.ParticipantsParticipants were >18 years, had cancer, an average nausea score of ≥3/10 and able to tolerate oral medications. Ineligible patients had acute nausea related to treatment, nausea for which a specific antiemetic was indicated, were about to undergo a procedure or had received either of the study drugs or a change in glucocorticoid dose within the previous 48 hours.InterventionsBased on previous studies, haloperidol was used as the control. Participants were randomised to encapsulated methotrimeprazine 6·25 mg or haloperidol 1·5 mg one time or two times per day and assessed every 24 hours for 72 hours.Main outcome measuresA ≥two-point reduction in nausea score at 72 hours from baseline. Secondary outcome measures were as follows: complete response at 72 hours (end nausea score less than 3), response at 24 and 48 hours, vomiting episodes, use of rescue antiemetics, harms and global impression of change.ResultsResponse to treatment at 72 hours was 75% (44/59) in the haloperidol (H) arm and 63% (36/57) in the methotrimeprazine (M) arm with no difference between groups (intention-to-treat analysis). Complete response rates were 56% (H) and 51% (M). In theper protocolanalysis, there was no difference in response rates: (85% (44/52) (H) and 74% (36/49) (M). Completeper protocolresponse rates were 64% (H) and 59% (M). Toxicity worse than baseline was minimal with a trend towards greater sedation in the methotrimeprazine arm.ConclusionThis study did not demonstrate any difference in response rate between methotrimeprazine and haloperidol in the control of nausea.Trial registration numberACTRN 12615000177550.

Vitamin A Status

Postpartum vitamin A supplementation of mothers and infants is recommended, but the efficacy has been questioned. In this double-blind, placebo-controlled trial, Kenyan mother–infant pairs were randomised to maternal vitamin A (400 000 IU) or placebo < 24 h postpartum, and infant vitamin A (100 000 IU) or placebo at 14 weeks. Milk retinol was determined at weeks 4, 14 and 26, and maternal and infant serum retinol at weeks 14 and 26. Infant retinol stores were assessed at week 26, using a modified relative dose response (MRDR) test. Among 564 women, serum retinol at 36 weeks gestation was 0·81 (sd 0·21) μmol/l, and 33·3 % were < 0·7 μmol/l. Maternal serum retinol was not different between groups, but milk retinol was higher in the vitamin A group: (0·67 v. 0·60 μmol/l; 0·52 v. 0·44 μmol/l; 0·50 v. 0·44 μmol/l at 4, 14 and 26 weeks, respectively). When expressed per gram fat, milk retinol was higher in the vitamin A group only at 4 weeks. Infant serum retinol was not different between groups. However, although most infants had deficient vitamin A stores (MRDR>0·06 %) at 26 weeks, vitamin A to infants, but not mothers, resulted in a lower proportion of infants with deficient vitamin A stores (69 v. 78 %). High-dose postpartum vitamin A supplementation failed to increase serum retinol and infant stores, despite modest effects on milk retinol. Infant supplementation, however, increased stores. There is a need for a better understanding of factors affecting absorption and metabolism of vitamin A.

ABSTRACT Background Gastroenteritis is a common and impactful disease in childhood. Probiotics are often used to treat acute gastroenteritis (AGE); however, in a large multicenter randomized controlled trial (RCT) in 971 children, Lactobacillus rhamnosus GG (LGG) was no better than placebo in improving patient outcomes. Objectives We sought to determine whether the effect of LGG is associated with age, weight z score and weight percentile adjusted for age and sex, or dose per kilogram administered. Methods This was a preplanned secondary analysis of a multicenter double-blind RCT of LGG 1 × 1010 CFU twice daily for 5 d or placebo in children 3–48 mo of age with AGE. Our primary outcome was moderate to severe gastroenteritis. Secondary outcomes included diarrhea and vomiting frequency and duration, chronic diarrhea, and side effects. We used multivariable linear and nonlinear models testing for interaction effects to assess outcomes by age, weight z score and weight percentile adjusted for age and sex, and dose per kilogram of LGG received. Results A total of 813 children (84%) were included in the analysis; 413 received placebo and 400 LGG. Baseline characteristics were similar between treatment groups. There were no differential interaction effects across ranges of age (P-interaction = 0.32), adjusted weight z score (P-interaction = 0.43), adjusted weight percentile (P-interaction = 0.45), or dose per kilogram of LGG received (P-interaction = 0.28) for the primary outcome. Whereas we found a statistical association favoring placebo at the extremes of adjusted weight z scores for the number of vomiting episodes (P-interaction = 0.02) and vomiting duration (P-interaction = 0.0475), there were no statistically significant differences in other secondary outcome measures (all P-interactions &gt; 0.05). Conclusions LGG does not improve outcomes in children with AGE regardless of the age, adjusted weight z score, and adjusted weight percentile of participants, or the probiotic dose per kilogram received. These results further strengthen the conclusions of low risk of bias clinical trials which demonstrate that LGG provides no clinical benefit in children with AGE. This trial was registered at clinicaltrials.gov as NCT01773967.

Intravenous Vitamin

Abstract Background High-dose intravenous vitamin C directly scavenges and decreases the production of harmful reactive oxygen species (ROS) generated during ischemia/reperfusion after a cardiac arrest. The aim of this study is to investigate whether short-term treatment with a supplementary or very high-dose intravenous vitamin C reduces organ failure in post-cardiac arrest patients. Methods This is a double-blind, multi-center, randomized placebo-controlled trial conducted in 7 intensive care units (ICUs) in The Netherlands. A total of 270 patients with cardiac arrest and return of spontaneous circulation will be randomly assigned to three groups of 90 patients (1:1:1 ratio, stratified by site and age). Patients will intravenously receive a placebo, a supplementation dose of 3 g of vitamin C or a pharmacological dose of 10 g of vitamin C per day for 96 h. The primary endpoint is organ failure at 96 h as measured by the Resuscitation-Sequential Organ Failure Assessment (R-SOFA) score at 96 h minus the baseline score (delta R-SOFA). Secondary endpoints are a neurological outcome, mortality, length of ICU and hospital stay, myocardial injury, vasopressor support, lung injury score, ventilator-free days, renal function, ICU-acquired weakness, delirium, oxidative stress parameters, and plasma vitamin C concentrations. Discussion Vitamin C supplementation is safe and preclinical studies have shown beneficial effects of high-dose IV vitamin C in cardiac arrest models. This is the first RCT to assess the clinical effect of intravenous vitamin C on organ dysfunction in critically ill patients after cardiac arrest. Trial registration ClinicalTrials.gov NCT03509662.

Abstract During the uploading of data for submission to the EudraCT results database, a discrepancy was identified. It was noted that the number of deaths per group was not consistent with the number in the final report and trial publication. This discrepancy was found to relate to two randomisation numbers. During the trial, the randomisation database had been held separately from the trial database, with manual transcription of randomisation numbers from the randomisation database to the trial database. Two randomisation numbers had been entered incorrectly into the trial database and, although this was documented at the time, the correction had not been made in the analysis data set. The two infants in question received the correct treatment in accordance with their allocation, but were analysed according to the wrong treatment group. Following the identification of this error, all analyses were repeated. It was confirmed that this error had a negligible impact on the study results. Furthermore, the two infants in question had not been included in the primary and secondary outcome analyses, as one had died and the other had withdrawn prior to the primary end-point assessment, so the key study outcomes remain unchanged. The only changes to the results are in the number of serious adverse events and minor changes to the data in demographics tables mostly affecting decimal points and the CONSORT diagram. Our interpretation of the study results remains unchanged.

Purpose: To assess the bioavailability and safety of vitamin D3 from fortified mozzarella cheese baked on pizza. Methods: In a randomized, double-blind trial, 96 apparently healthy, ethnically diverse adults were randomized to consume 200 IU or 28 000 IU vitamin D3 fortified mozzarella cheese with pizza once weekly for a total of 8 weeks. Blood and urine samples were collected at baseline (week 1) and final (week 10) visits for serum 25-hydroxyvitamin D and other biochemical measures. The primary outcome compared serum 25-hydroxyvitamin D between groups at 10 weeks. The secondary outcome evaluated the safety of vitamin D dosing protocol as measured by serum and urine calcium, phosphate, creatinine, and serum parathyroid hormone (PTH). Results: Serum 25-hydroxyvitamin D increased by 5.1 ± 11 nmol/L in the low-dose group (n = 47; P = 0.003), and by 73 ± 22 nmol/L in the high-dose group (n = 49; P < 0.0001). None of the subjects in either group developed any adverse events during the supplementation protocol. Serum PTH significantly decreased in the high-dose group only (P < 0.05). Conclusions: Vitamin D3 is safe and bioavailable from fortified mozzarella cheese baked on pizza.
