Investigating the Contribution to Fire Growth of Combustible Materials Used in Building Components
Authors: Rogowski B.F.W. 
Published: August 2023

Recent work at the Fire Research Station has provided a measure of the possible contribution to fire growth from the combustion of such components as wall or ceiling panels rather than the well-known contribution from surface spread of flame on wall and ceiling linings. The oxygen depletion technique has been used to assess the rate of heat release from wall panels with a range of facing materials and different cellular polymer cores. The paper discusses how such an experimental approach may be adapted to direct validating modelling techniques with certain components but must take account of the variability in existing building practices.

Background This multicenter cross-sectional study aimed to determine the frequency and characteristics of secondary headaches in different geographic regions, including Turkey, the Middle East, Asia, and Africa. Methods Patients were admitted to the study on a particular day each week for five consecutive weeks between 1 April and 16 May 2022. Before the study, all researchers underwent a constructed briefing about the use and code of the ICHD-3 criteria. The study was conducted in two stages. In the first stage, data on secondary headaches were compared between the regions. In the second stage, the sub-diagnoses of secondary headaches were analyzed only in Turkey. Results A total of 4144 (30.0%) of the 13,794 patients reported headaches as the main symptoms at admission. A total of 422 patients were excluded from the study. In total, 1249 (33.4%) of 3722 patients were diagnosed as having secondary headaches (Turkey [n = 1039], Middle East [n = 80], Asia [n = 51], Africa [n = 79]). The frequency of secondary headaches (Turkey 33.6%, Africa 30.1%, Middle East 35.5%, Asia 35.4%) did not differ significantly between the regions (p > 0.05). The most common subtype of secondary headaches was headache attributed to substances or their withdrawal in all the studied regions. There was a female predominance in all regions, but it was lower in Africa than in Turkey. The severity and density of headaches differed significantly between the regions, with patients from Africa reporting milder pain than patients from other regions. In Turkey, the most common sub-diagnoses of secondary headaches were medication overuse headache, idiopathic intracranial hypertension, and cervicogenic headache. Conclusion In the present study, one in three patients with a headache had a secondary headache. Headache attributed to substances or their withdrawal was the most common subtype of secondary headaches in all the studied regions. The female predominance of secondary headaches was lower in Africa than in Turkey. The severity and density of headaches differed significantly between regions, with patients from Africa reporting milder pain.

Published: August 2023

Background: Rotator cuff tear size, fatty infiltration, and scapular morphology are correlated with tendon healing and functional outcomes after arthroscopic repair; however, the association between anteroposterior acromial coverage and the clinical outcomes of anteroposterior massive rotator cuff tears (AP-MRCTs; involving all 3 tendons) remains unclear. Purpose: To identify the association between AP acromial coverage and functional and radiological outcomes after arthroscopic repair of AP-MRCTs. Study Design: Cohort study; Level of evidence, 3. Methods: A total of 98 patients who underwent arthroscopic repair of AP-MRCTs between January 2015 and December 2020 were included in the study and classified according to whether anterior acromial coverage (AAC) was anterior (46 patients; positive AAC group) or posterior (52 patients; negative AAC group) to the scapular line on true lateral shoulder radiographs. Demographic characteristics, surgical details, and functional outcomes were prospectively collected. Acromial morphological features, global tear extension (GTE), the global fatty infiltration index (GFII), tendon integrity after repair, proximal humeral migration, and glenohumeral abduction were measured and calculated on radiographs or magnetic resonance imaging scans preoperatively and at 2 years postoperatively. Multivariate logistic regression was performed to identify the independent risk factors of a rotator cuff retear. Results: The positive AAC group showed larger AAC, posterior acromial tilt, and anterior acromial slope as well as smaller posterior acromial coverage compared with the negative AAC group. Postoperatively, the American Shoulder and Elbow Surgeons score (82.5 ± 8.3 vs 77.2 ± 11.5, respectively; P = .013), active abduction (157.8°± 27.1° vs 142.7°± 39.6°, respectively; P = .048), and glenohumeral abduction (45.6°± 10.4° vs 39.7°± 14.9°, respectively; P = .041) in the positive AAC group were significantly higher than those in the negative AAC group, while the retear rate (23.9% vs 44.2%, respectively; P = .035) and proximal humeral migration (1.7 ± 1.0 vs 2.3 ± 1.2 mm, respectively; P = .006) were significantly lower in the positive AAC group than in the negative AAC group. Smaller AAC (odds ratio [OR], 0.93 [95% CI, 0.87-1.00]; P = .040), larger GTE (OR, 1.03 [95% CI, 1.01-1.06]; P = .017), and a higher GFII (OR, 3.49 [95% CI, 1.09-11.19]; P = .036) were associated with an increased risk of a rotator cuff retear. Conclusion: Increased AAC was associated with a lower retear rate and better functional outcomes after arthroscopic repair of AP-MRCTs. A preliminary risk evaluation integrating GTE, the GFII, and AAC is recommended to consider the necessity of additional procedures for patients in need of arthroscopic rotator cuff repair.

Published: August 2023

Background: Breastfeeding self-efficacy has been proven to play a predictive role in enhancing breastfeeding initiation and continuation. Breastfeeding self-efficacy measurement tools have facilitated healthcare professionals’ early identification and support of women at higher risk of early discontinuation of breastfeeding. Research Aim: The aim of this study was to assess the psychometric properties of breastfeeding self-efficacy measurement tools. Method: A systematic review was carried out in three phases. Phase One comprised a systematic literature review performed in PubMed, SCOPUS, Web of Science, and Cochrane Database of Systematic Reviews from February 2021 to January 2023, including 36 studies for final analysis. Phase Two provided a quality appraisal of the psychometric properties of each of the seven breastfeeding self-efficacy measurement tools, according to COnsensus-based Standards for the selection of health Measurement Instrument checklist (COSMIN) guidelines. Phase Three summarized and graded the overall quality of evidence using the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) modified approach. Result: The included articles comprised 9,225 participants and seven breastfeeding self-efficacy measurement tools. The Breastfeeding Self-Efficacy Scale, Breastfeeding Self-Efficacy Scale – Short Form (BSES-SF), and Prenatal Breastfeeding Self-Efficacy Scale were supported by Grade A evidence sustaining their validity and reliability to assess breastfeeding self-efficacy in the continuum of maternity care. The BSES-SF is the most feasible tool in clinical practice and the most utilized internationally, available in 15 languages. Conclusion: This systematic review provided a Grade A recommendation on breastfeeding measurement tools that will be helpful both for clinical and research purposes.

Published: August 2023

This paper presents an overall scheme of a long-endurance small solar-powered convertible unmanned aerial vehicle (CUAV) that operates tilt-rotor for multiple hover tasks. First, a solar/battery hybrid energy strategy was proposed to comprehensively meet the requirements of CUAVs with long endurance and multiple hovers. The particular ability of the solar-powered fixed-wing unmanned aerial vehicle (UAV), pure battery-powered CUAV, and the proposed long-endurance solar-powered CUAV with multiple cruises and hovers were comparatively analyzed from an energy standpoint. Second, a suitable conceptual design method and process for small solar-powered CUAV was given, and the robustness of the designed CUAV was using three performance metrics under nominal conditions. The approach was then applied to design a 6.5 kg CUAV, which was initially tested in flight. Finally, the performance and application potential of the designed CUAV was evaluated with operating conditions, mission requirements, energy input, and perpetual flight capability.

Limited information is available regarding the efficacy of antiretrovirals in people with HIV-1 and high or very high Body Mass Index (BMI). This is especially the case for the alafenamide salt of tenofovir as clinical trials have only enrolled patients with BMI ≤30 kg/m2. Lower concentrations of some antiretrovirals are expected in patients with BMI >30 kg/m2 due to potential changes in clearance and distribution of medication. This report describes an individual taking tenofovir alafenamide, emtricitabine and efavirenz in whom HIV-1 viral load was consistently undetectable (<50 copies/ml) over a 2.5 year period. During this period the patient’s BMI ranged between 59.8 and 68.1 kg/m2. Further data is required to support the efficacy of antiretrovirals in individuals with high and very high BMI.

Background Meditation using the “OM” mantra is the most widely used practice in India. Though reports have been published about the relaxation effect during both verbal “OM” chanting and listening to “OM” chanting, there is a paucity of literature concerning the cortical areas activated/deactivated after verbal “OM” chanting and listening to “OM” chanting using quantitative electro-encephalography (qEEG). Purpose The objective of this study was to compare the effects of verbal “OM” chanting and listening to “OM” chanting on cortical sources as compared to baseline, as assessed by qEEG. Method Twenty adult male subjects with a mean age of 27.5 ± 7.5 years and no past or present history of psychiatric, neurological, or auditory disorders or previous exposure to yoga and meditation were recruited from the undergraduate and postgraduate student population of AIIMS, New Delhi. Subjects were given a paradigm designed using E-prime for both verbal and listening to “OM” chanting of 5 min each and a 5-min relaxation period in between the tasks. Electroencephalography recording was done using a 128-channel geodesic sensor net with band-pass filtered at 1–70 Hz, and 20-sec data of eyes-closed condition, post-verbal “OM”, and post-listening to “OM” chanting were segmented and pre-processed. Further, source analysis was performed on the data using standardized low-resolution electromagnetic tomography. Result The pre (baseline) versus post-verbal “OM” ( p < .05) and post-listening to “OM” ( p < .05) chanting showed significant differences in similar cortical areas in both verbal “OM” and listening to “OM” chanting except the three areas, that is, the orbital gyrus, the rectal gyrus, and the sub-callosal gyrus, which were additionally activated post-listening to “OM” chanting. Both verbal and listening to “OM” chanting induced activation of similar cortical areas, which were classified as the nodes/hubs of specific resting-state networks (RSNs) such as the attentional network, frontoparietal control network, and default mode network. Conclusion The study results suggest that “OM” chanting could facilitate flexible switching between various RSNs to induce a relaxed state and could improve attention simultaneously. Both verbal and listening to “OM” chanting induced common activated areas that are classified into frontoparietal, dorsal attention, and default mode network areas. And it is hypothesized that flexible switching between these RSNs could induce a relaxed state and improve attention simultaneously with the possible role of the frontoparietal network.

Published: August 2023

Background Indian females have been objectified since time immemorial. The ancient Indian texts and architecture have numerous instances of sexual objectification of females. In the present time, self-objectification in girls is evident from the increasing popularity of apps like Photoshop, the rise in the makeup industry, plastic and cosmetic surgeries, and so on. This is especially relevant for females across the globe and leads to huge negative effects on women’s identities. Purpose The aim of the present study is to assess and compare the levels of body surveillance (self-objectification), body shaming, and control beliefs in adolescent girls from co-educational schools and all-girls schools. Methods Four hundred adolescent girls from Convent schools in different cities in Uttar Pradesh were included in the study using purposive (homogeneous) sampling based on the inclusion criteria. The Objectified Body Consciousness Scale (OBCS) was used to assess body surveillance (self-objectification), body shaming, and control beliefs. Results The results of the study revealed that the level of body surveillance (self-objectification) was significantly high among Indian adolescent girls. It was found that all-girls schools had a higher level of body surveillance (self-objectification), body shaming, and control beliefs as compared to adolescent girls from co-educational schools. Conclusion It can be concluded that the phenomenon of self-objectification has numerous implications for the physical and mental well-being of girls, particularly during their formative years. Healthy behaviors and positive thoughts are the best ways to respect and honor one’s body. The research suggests the need for meditation, awareness workshops, and school-level counseling for adolescent girls, especially in all-girls schools.

Background: Advanced glycation end products (AGEs) impair vascular physiology in Diabetes mellitus (DM). However, the underlying mechanisms remain unclear. Vascular large conductance calcium-activated potassium (BK) channels play important roles in coronary arterial function. Purpose: Our study aimed to investigate the regulatory role of AGEs in BK channels. Research Design: Using gavage of vehicle (V, normal saline) or aminoguanidine (A) for 8 weeks, normal and diabetic rats were divided into four groups: C+V group, DM+V group, C+A group, and DM+A group. Study Sample: Coronary arteries from different groups of rats and human coronary smooth muscle cells were used in this study. Data Collection and Analysis: Data were presented as mean ± SEM (standard error of mean). Student's t-test was used to compare data between two groups. One-way ANOVA with post-hoc LSD analysis was used to compare data between multiple groups. Results: Compared to the C+V group, vascular contraction induced by iberiotoxin (IBTX), a BK channel inhibitor, was impaired, and BK channel densities decreased in the DM+V group. However, aminoguanidine administration reduced the impairment. Protein expression of BK-β1, phosphorylation of adenosine 5’-monophosphate-activated protein kinase (AMPK), and protein kinase B (PKB or Akt) were down-regulated, while F-box protein 32 (FBXO32) expression increased in the DM+V group and in high glucose (HG) cultured human coronary smooth muscle cells. Treatment with aminoguanidine in vitro and in vivo could reverse the above protein expression. The effect of aminoguanidine on the improvement of BK channel function by inhibiting the generation of AGEs was reversed by adding MK2206 (Akt inhibitor) or Compound C (AMPK inhibitor) in HG conditions in vitro. Conclusions: AGEs aggravate BK channel dysfunction via the AMPK/Akt/FBXO32 signaling pathway.
Effect of Internal Carotid Artery Doppler Peak Systolic Velocity Thresholds for Classifying Ipsilateral Ischemic Stroke Due to Large Artery Atherosclerosis According to the Trial of Org 10172 in Acute Stroke Treatment (TOAST) System
Authors: Polak Joseph F. 
Published: August 2023

Background: A Doppler peak systolic velocity (PSV) of 125 cm/s has been used to indicate an internal carotid artery 50% stenosis, a marker of large artery atherosclerosis (LAA) when classifying ischemic stroke according to the Trial of Org 10172 in Acute Stroke Treatment (TOAST). Shifting this cut point to 180 cm/s might affect the classification of ischemic stroke. Methods: Color Doppler–assisted measurements of PSV were performed at the baseline visit of a large longitudinal cohort study in the United States: the Cardiovascular Health Study (CHS). Incident ischemic stroke within the following 6 years was ascertained by adjudicated review of medical records. The side of ischemic stroke was recorded. Incidence rates and odds ratios (logistic regression models) were estimated at the respective 125 cm/s and 180 cm/s cut points. Results: Mean age was 72.8 years with 57.6% women. A total of 11 425 bifurcations had PSV measurements. Of the 514 carotid bifurcations with PSV above 125 cm/s, 20 ipsilateral incident strokes were seen, whereas 6 strokes occurred among the 126 bifurcations with PSV above 180 cm/s. Shifting the cut point decreased categorizing ischemic stroke as due to LAA by 70% (14/20). The odds ratio (1.75; 95% confidence interval, 1.01-3.02) of incident stroke for a PSV between 125 cm/s and 180 cm/s was significant ( P < .05) when compared with a PSV <125 cm/s. Conclusion: Shifting the PSV cut point for a 50% carotid stenosis from 125 cm/s to 180 cm/s would have significant implications when categorizing ischemic stroke as being associated with LAA.

Background The carotid artery stenting (CAS) has two common access sites: transradial access (TRA) and transfemoral access (TFA). However, there's no definitive answer to which one is superior. Objective Compare TRA and TFA for the CAS. Methods A systematic review of the literature of studies reporting both TRA and TFA results was conducted following the PRISMA guidelines. PubMed, Cochrane Library, Web of Science and Embase were queried. Results The meta-analysis examined nine studies comprising 7513 patients who underwent CAS. Of these, 6750 patients had TFA (90%), while 763 had TRA (10%). There was no significant difference in procedure success rates between TRA and TFA, with a risk ratio (RR) of 0.99 (6/9; 95% CI 0.98 to 1.00; I² = 9%, fixed effects). However, cross-over to TFA was more frequent in TRA (odds ratio (OR) 10.37 (6/9; 95% CI 5.18 to 20.77; I² = 17%, fixed effects)). There were no significant differences in terms of major access complications (RR = 0.88 (7/9; 95% CI: 0.29 to 2.63; I² = 0, fixed effects)), total access complications (RR = 1.10 (6/9; 95% CI: 0.56 to 2.15; I² = 7%, fixed effects)), and mean difference in length of stay (Mean difference of −0.08 (3/9; 95% CI −0.18 to 0.02; I² = 0%, fixed effects)). Conclusion There were no significant differences between TFA and TRA in terms of procedure success rates, time, complications, and length of stay, although cross-over to TFA was more common in TRA cases.
The prevalence and determinant factors for alcohol abuse in Gondar city’s preparatory schools: a cross-sectional study
Authors: Wondimu Habtamu 
Published: August 2023

Objectives: Alcohol abuse is more prevalent among preparatory schools in Ethiopia. Although alcohol abuse has become a significant health problem in Ethiopia, governmental and non-governmental organizations have not devoted enough attention to preventing and rehabilitating those who have difficulties with alcoholism. This study examined the prevalence and related factors of alcohol abuse in Gondar’s preparatory schools. Methods: The study used a mixed-methods research approach supported by a school-based cross-sectional design from April 2020 to June 2020 to get reliable and valid data. Through the use of stratified sampling techniques, the study drew a total of 196 students who were addicted to alcohol consumption. Results: The result of this study revealed that most of the students in the study areas drink alcohol occasionally; the reason they engage in alcoholic consumption is to satisfy personal desires and get respite from strain. Moreover, peer pressure and societal and student familial backgrounds were among the factors that exposed students to the heavy drinking habit. Conclusions: To avoid such barriers, the study urges the schools to work on a wakefulness campaign or make students aware of the adverse effects of alcohol and related substances through school media.
