Authors: Hammond Nicole G. , Colman Ian 
Published: April 2020

BackgroundThe use of diet and physical activity in alleviating the burden of migraine is unclear, therefore, more scientific study on the role of positive health behaviors in migraine management is needed.ObjectiveTo explore the potential moderating influence of positive health behaviors on the early life stress‐migraine relationship in a sample of the Canadian adult population.MethodsThis study used data from the 2011‐2012 Canadian Community Health Survey – Annual Component, a National cross‐sectional survey. Adults ≥18 years of age residing in British Columbia were surveyed about stressors experienced as children/teenagers (eg, parental divorce and substance abuse exposure). Migraine was self‐report of health‐professional diagnosis. Positive health behaviors were measured using an index of transportation and leisure time physical activity, and self‐reported frequency of vegetable and fruit consumption. Population survey weights were employed throughout and analytic models were adjusted for known confounders (nunweighted = 11,910).ResultsThe weighted prevalence of migraine was 9.7% (95% CI: 9.1%, 10.2%). Odds of migraine increased as number of stressors increased: 1 early life stressor (OR = 1.18, 95% CI: 1.01, 1.39), and ≥ 2 early life stressors (OR = 1.51, 95% CI: 1.29, 1.76), compared to no stress. There was evidence of effect modification by physical activity (χ2(4) = 16.02,P < .001). The association between 1 early life stressor and migraine was lower for those who were physically active (moderately active: OR = 1.20, 95% CI: 0.90, 1.61; active: OR = 0.82, 95% CI: 0.61, 1.11). This difference was not apparent for those who experienced 2 or more early life stressors (moderately active: OR = 1.67, 95% CI: 1.28, 2.17; active: OR = 1.55, 95% CI: 1.21, 1.99). Across all levels of early life stress, physically active respondents had lower odds of migraine than moderately active respondents. There was no effect modification by vegetable, fruit, and total fruit/vegetable consumption.ConclusionsStressors experienced early in life are associated with migraine, and physical activity may ameliorate this relationship, particularly for those with exposure to a minimal level of early life stress. A higher dose of physical activity may yield greater benefit than a less intensive dose (ie, moderate activity level). However, the cross‐sectional nature of this study precludes us from inferring causality, and future investigation requires prospectively collected data.

ObjectiveTo systematically identify risk factors for the development of post‐traumatic headache (PTH) attributed to traumatic brain injury (TBI) as defined in the International Classification of Headache Disorders (ICHD).BackgroundPTH is a common sequela of TBI and a leading cause of injury‐related disability worldwide. However, little is known about risk factors for the development of PTH attributed to TBI.MethodsWe searched PubMed and Embase for literature on risk factors for the development ofacuteand/orpersistentPTH attributed to TBI in accordance with any version of the ICHD. Original studies published in English and of prospective, cross‐sectional or retrospective design were considered for the review. Data extraction was performed independently by 2 investigators.ResultsOf 1993 potentially relevant articles identified, 3 articles met the inclusion criteria. The following risk factors were assessed for the development ofacutePTH: age, sex, type of injury, loss of consciousness, previous TBIs, history of primary headache disorders, history of chronic pain condition other than headache, current treatment for depression/anxiety, attention or learning disorders, body mass index, and other diseases (not further specified). None of the included studies assessed risk factors for the development ofpersistentPTH.ConclusionsWe found that there is little evidence for any risk factors involved in the development ofacutePTH, whereas no study had assessed risk factors for the development of persistent PTH. Further studies are warranted and should be powered to examine possible risk factors for the development of PTH. Rigorous methodology and standardized monitoring should be prioritized to support high‐quality research and validate potential findings.

ObjectivesThis study evaluated headaches among Parkinson’s disease (PD) patients and whether there was any correlation between the motor symptoms and the severity of the headaches presented.BackgroundForty to 83% of PD patients are affected by pain. Despite this high prevalence of pain, only a few studies have addressed the headaches of these patients.MethodsThis was a cross‐sectional study. Consecutive patients with Parkinson disease were included. Semi‐structured interview; the Epworth sleepiness scale; the Hospital Anxiety and Depression Scale; the Unified Parkinson’s Disease Rating Scale (UPDRS), Part III (motor examination); and the Hoehn and Yahr scale were used.ResultsAbout 46 patients were included, 52% were men, mean age was 66 ± 11 years. Forty‐three patients had headaches, 12/46 (26%), migraines, 31/46 (67%) had tension‐type headaches. We found no association between the headache frequency (median: 0.5; 0.5 to 7.5 vs 0.5; 0.5 to 8 days/3 months; P = .757) or intensity (median: 5; 4 to 8 vs 5.5, 4 to 9; P = .514) and the different stages of the PD (Hoehn and Yahr scale: ≤2.5 vs >2.5). There was no correlation between UPDRS score and the intensity (r = −0.099; P = .530) or frequency of headaches (r = −0.136; P = .373). No association was found between the grade of neck stiffness (0 vs 1 and 2 vs 3 and 4) and the headache frequency (Median: 0; 0 to 3 vs 3.5; 0 to 12.5 vs 0; 0 to 6 days/3 months; P = .074) or intensity (Median: 5; 3 to 9 vs 5; 4 to 6 vs 7; 4.5 to 9; P = .434). Twelve patients said that their headaches started after PD had been diagnosed. There was no difference regarding the frequency and characteristics of headaches and PD characteristics between these patients and the other patients with previous headaches.ConclusionsIn this sample of PD patients, there is no association between headache and PD.

AbstractThis study is concerned with the tectono‐thermal history of the Kathmandu nappe and the underlying Lesser Himalayan sediments (LHS) that are distributed in eastern Nepal. We carried out zircon fission‐track(ZFT) dating and obtained 16 ZFT ages from the eastern extension of the Kathmandu nappe, the Higher Himalayan Crystalline, Kuncha nappe, and the Main Central Thrust (MCT) zone. The ZFT ages of the frontal part of the Kathmandu nappe range from 13.0 ±0.8 Ma to 10.7 ±0.7 Ma and exhibit a northward‐younging tendency. These Middle Miocene ZFT ages indicate that the frontal part of the Kathmandu nappe remained at a temperature above 240 °C until the termination of its southward emplacement at 12–11 Ma. The ZFT ages of the LHS range from 11.1 ±0.9 Ma in the southern part of the Okhaldhunga Window to 2.4 ±0.3 Ma of the augen gneiss in the northern margin and also exhibit a northward‐younging age distribution. The ZFT ages show the northward‐younging linear distribution pattern (−0.16 Ma/km) along the across‐strikesection from the frontal part of the Kathmandu nappe to the root zone, without a significant age gap. This distribution pattern indicates that the Kathmandu nappe, the underlying MCT zone, and the Kuncha nappe cooled from the frontal zone to the root zone as a thermally united geologic body at a temperature below 240 °C. An older ZFT age (456.3 ±24.3 Ma), which was partially reset at the axial part of the Midland anticlinorium in the central part of the Okhaldhunga Window, was explained by downward heating from the “hot” Kathmandu nappe. The above evidence supported a model that southward emplacement of the hot Kathmandu nappe resulted in a thermal imprint on the upper part of the LHS; however, the lower part did not reach 240 °C.

SummaryClostridium tyrobutyricum causes swelling, cracks and off‐flavours of cheeses (late blowing defect, LBD) due to butyric acid fermentation. To control this spoilage bacterium, we investigated the use of nisinogenic Lactococcus lactis subsp. lactis INIA 415 as starter in cheeses contaminated with C. tyrobutyricum spores. Control cheese made with spores showed LBD after 14 days of ripening. However, in cheese made with the bacteriocin producer and spores, in which (unlike control cheese) bacteriocin activity was detected throughout ripening, LBD occurred after 21 days. At this stage, level of lactic acid was 1.22‐fold higher (P < 0.01) and concentrations of propionic and butyric acids were 2.15‐ and 2.32‐fold, respectively, lower (P < 0.01) in cheese made with the nisin producer than in control cheese, according to the less pronounced spoilage symptoms showed by the former cheese. The bacteriocin producer delayed the appearance of LBD, although it cannot arrest completely C. tyrobutyricum growth.

SummaryThe influence and mechanism of ingredient mixing procedure on the quality characteristics of noodle enriched with hulless barley flour were investigated. Dough crumb mixing (DC‐M) procedure was used to prepare wheat and hulless barley crumbly dough, respectively, then mixed and sheeted. Flour mixing (F‐M) procedure referred to mixing wheat and hulless barley flour thoroughly before adding water. Dough sheet mixing (DS‐M) procedure was that wheat and hulless barley dough sheet were prepared, respectively, and then stacked up together for sheeting. The results showed that DC‐M procedure could improve the uniformity of water distribution and presented a better gluten network. Noodle made by DC‐M showed the highest sensory score, best texture and cooking properties. According to the investigations of dynamic rheological, water distribution and microstructure of dough and/or noodle, the mechanism of improving noodle quality by DC‐M may be attributed to the weakening effects on fibre as a physical barrier, then reduce the competitive absorption of water by fibre with gluten, which contributed to a more uniform and compact gluten network structure. This study provided an available way to prepare good quality noodles with non‐gluten and high dietary fibre grains with no chemical additives, just by changing the ingredient mixing procedure.

AbstractA cluster of pneumonia (COVID‐19) cases have been found in Wuhan China in late December, 2019, and subsequently, a novel coronavirus with a positive stranded RNA was identified to be the aetiological virus (severe acute respiratory syndrome coronavirus 2, SARS‐CoV‐2), which has a phylogenetic similarity to severe acute respiratory syndrome coronavirus (SARS‐CoV). SARS‐CoV‐2 transmits mainly through droplets and close contact and the elder or people with chronic diseases are high‐risk population. People affected by SARS‐CoV‐2 can be asymptomatic, which brings about more difficulties to control the transmission. COVID‐19 has become pandemic rapidly after onset, and so far the infected people have been above 2 000 000 and more than 130 000 died worldwide according to COVID‐19 situation dashboard of World Health Organization (https://covid19.who.int). Here, we summarized the current known knowledge regarding epidemiological, pathogenesis, pathology, clinical features, comorbidities and treatment of COVID‐19/ SARS‐CoV‐2 as reference for the prevention and control COVID‐19.

AbstractAimAssessing the application of three‐dimensional clinical attachment loss (3D‐CAL), 3D supporting bone loss (3D‐SBL), supracrestal tissue attachment (STA), and crown‐to‐root ratio (CRR) in evaluating the 2017 periodontitis classification.Materials and methodsWe analysed ninety single‐rooted human premolars with micro‐computed tomography. The amount of 3D‐SBL, linear radiographic bone loss (RBL), and CRR corresponding to various periodontitis stages as well as the statistical significance was investigated.ResultsFrom a 3D perspective, the premolars with a 21% of 3D‐SBL at 2.0 mm coronal root length (RL) and 15% RBL corresponded to the periodontitis stage I. Premolars with a 44% of 3D‐SBL at coronal 4.2‒4.4 mm RL and 33% RBL accorded with the periodontitis stage II. Excluding the consideration of STA, CRR = 5:6 and 4:3 were associated with the levels at 15% and 33% RBL, respectively.ConclusionsA greater percentage of 3D‐CAL than that of 2D‐CAL is significant at evaluated levels. It is feasible to correlate the 3D‐SBL, 3D‐CAL, and STA parameters to evaluate the stages of periodontitis severity. However, the current use of RBL and CAL as applied for staging in the 2017 classification might be inconsistent with the evaluated premolar roots length, when STA dimensions are considered.

Published: April 2020

AbstractLyme disease cases are increasing in the United States. The vector of the pathogen that causes Lyme disease is the blacklegged tick (Ixodes scapularis Say) (Acari:Ixodidae). While there are several tick control options, many are expensive or involve large‐scale or ecological interventions such as landscape acaricide spraying or wildlife baiting. Tick control tubes, cardboard tubes with acaricide‐treated cotton that can be used as nesting material by tick hosts, offer an alternative to more invasive tick control by treating tick hosts with an acaricide. In this study, tick tubes with cotton treated with two formulations of acaricide and water as a control were evaluated for wildlife use and for tick burden reductions on Peromyscus spp. an important reservoir host for the Lyme disease pathogen. Tick tubes were deployed for four weeks. Ticks parasitizing Peromyscus spp. and cotton use by wildlife were evaluated pre‐deployment and post‐deployment. Cotton from both treatments was used similarly, and permethrin‐treated cotton was used more frequently than the control. In addition, I. scapularis were eliminated from hosts captured in treatment plots post‐tick tube deployment. Tick tubes show promise as a tool for tick control on Peromyscus spp., especially as part of an integrated pest management plan.

AbstractCronobacter sakazakii (C. sakazakii) is an opportunistic, neonatal, and food borne pathogen primarily associated with the contamination of powdered infant formula (PIF). The pathogen is reported to overcome the food safety barriers such as increased acidity, heat treatment, and so on. This study evaluates the thermal tolerance of C. sakazakii strains independently at 52, 55, and 58°C in reconstituted PIF after exposure to physiological stresses: refrigeration (4°C for 24 hr), starvation (37°C for 48 hr), and desiccation (25°C for 4 days). The Log10 CFU/ml and D‐values indicated that survival rate of all the strains decreased significantly (p < .05) after desiccation as compared to those of the control condition (without stress exposure). However, cold stress increased the thermal tolerance of all strains at all temperatures (52, 55, and 58°C) as indicated by increased D‐values. Among the tested strains, C. sakazakii strain N15 was found to be the most resistant to thermal treatment after each stress exposure as depicted by principal component analysis (PCA). No apparent correlation between thermal tolerance and starvation stress was observed. The findings indicate that prior exposure to stress conditions may induce cross protection to thermal treatment in C. sakazakii.

AbstractBackgroundPositive health outcomes have been observed following gastrostomy insertion in children with intellectual disability, which is being increasingly used at younger ages to improve nutritional intake. This study investigated the effect of gastrostomy insertion on survival of children with severe intellectual disability.MethodsWe used linked disability and health data of children and adolescents who were born in Western Australia between 1983 and 2009 to compare survival of individuals with severe intellectual disability by exposure to gastrostomy status. For those born in 2000–2009, we employed propensity score matching to adjust for confounding by indication. Effect of gastrostomy insertion on survival was compared by pertinent health and sociodemographic risk factors.ResultsCompared with children born in the 1980s–1990s, probability of survival following first gastrostomy insertion for those born in 2000–2009 was higher (2 years: 94% vs. 83%). Mortality risk was higher in cases than that in their matched controls (hazard ratio 2.9, 95% confidence interval 1.1, 7.3). The relative risk of mortality (gastrostomy vs. non‐gastrostomy) may have differed by sex, birthweight and time at first gastrostomy insertion. Respiratory conditions were a common immediate or underlying cause of death among all children, particularly among those undergoing gastrostomy insertion.ConclusionsWhilst gastrostomy insertion was associated with lower survival rates than children without gastrostomy, survival improved with time, and gastrostomy afforded some protection for the more vulnerable groups, and earlier use appears beneficial to survival. Specific clinical data that may be used to prioritise the need for gastrostomy insertion may be responsible for the survival differences observed.

AbstractBackgroundA monopolar radiofrequency device can be used in facial tightening. The device targets the dermis and fibrous septae, and the treatment results in immediate collagen contraction and the induction of subsequent collagen remodeling.AimsWe aimed to evaluate the histometric change of the subjects treated with a monopolar radiofrequency device using a novel tip.Materials and methodsEleven subjects with skin types III and IV participated in the study. They received a single session of a monopolar radiofrequency on the face, and biopsies were performed before treatment, and 2 and 6 months after the treatment. Hematoxylin and eosin, Masson trichome, and Victoria blue stains were used. An image analysis was performed using the Image J software. The dermal density of collagen and elastic fiber, and the coherency of collagen fibers were assessed in the papillary, upper reticular, and lower reticular dermises, respectively.ResultsThe monopolar radiofrequency treatments led to improvements in collagen fiber density and coherency. In the Masson trichome staining, the collagen fiber densities were 0.736 ± 0.06 and 0.652 ± 0.063 before treatment and increased to 0.773 ± 0.044 (P = .018) and 0.686 ± 0.05 (P = .045) in the papillary and lower reticular dermises, respectively. The density of the elastic fibers in all parts of the dermis showed a tendency to increase after treatment, though not statistically significantly. The mean coherency was higher after than before treatment.ConclusionsIn this in vivo study, we found that the collagen and elastic fiber densities and architectural structures were improved after treatment.

AbstractAims and objectivesTo evaluate the efficacy and safety of a comprehensive protocol for constipation prevention.BackgroundConstipation is a common problem for patients undergoing total hip arthroplasty (THA), yet sparse evidence is available to guide constipation prevention after THA.DesignRandomised controlled superiority clinical trial.MethodsThis randomised controlled study was carried out according to the Consolidated Standards of Reporting Trials (CONSORT). A total of 80 THA patients were randomised to receive only preoperative education about lifestyle or the combination of education with postoperative abdominal massage and polyethylene glycol 4,000 (Forlax®). Efficacy outcomes included rates of postoperative constipation and enema rescue, as well as time to first postoperative defecation and readmission within 30 days. Safety outcomes were number and type of adverse events.ResultsPatients who received combination treatment showed a significantly lower rate of postoperative constipation during hospitalisation than patients who received only preoperative education (25% versus 55%), and they showed a significantly lower rate of enema rescue (12.5% versus 40%). Many more patients receiving combination treatment experienced their first defecation within two postoperative days than patients who received only preoperative education (62.5% versus 35.9%). In contrast, the two groups were similar in terms of constipation rate on postoperative days 15 and 30, rate of readmission within 30 days and rate of postoperative adverse events.ConclusionsThese results suggest that our comprehensive protocol can relieve constipation after THA, reduce the need for enema rescue and shorten time to first defecation without sacrificing safety. More work is needed to optimise and develop this protocol further.Relevance to clinical practiceConstipation is a distressing problem that frequently occurs after THA. This study confirmed that a comprehensive protocol including preoperative education, postoperative abdominal massage and polyethylene glycol 4,000 can effectively relieve constipation after THA without sacrificing safety.
