BackgroundThe emergence of the COVID-19 pandemic has affected the lives of many people, including medical students. The present study explored internet addiction and changes in sleep patterns among medical students during the pandemic and assessed the relationship between them.MethodsA cross-sectional study was carried out in seven countries, the Dominican Republic, Egypt, Guyana, India, Mexico, Pakistan, and Sudan, using a convenience sampling technique, an online survey comprising demographic details, information regarding COVID-19, the Pittsburgh Sleep Quality Index (PSQI), and the Internet Addiction Test (IAT).ResultsIn total, 2749 participants completed the questionnaire. Of the total, 67.6% scored above 30 in the IAT, suggesting the presence of an Internet addiction, and 73.5% scored equal and above 5 in the PSQI, suggesting poor sleep quality. Internet addiction was found to be significant predictors of poor sleep quality, causing 13.2% of the variance in poor sleep quality. Participants who reported COVID-19 related symptoms had disturbed sleep and higher internet addiction levels when compared with those who did not. Participants who reported a diagnosis of COVID-19 reported poor sleep quality. Those living with a COVID-19 diagnosed patient reported higher internet addiction and worse sleep quality compared with those who did not have any COVID-19 patients in their surroundings.ConclusionThe results of this study suggest that internet addiction and poor sleep quality are two issues that require addressing amongst medical students. Medical training institutions should do their best to minimize their negative impact, particularly during the current COVID-19 pandemic.

Published: November 2021

BackgroundIn ischemic stroke patients with active cancer, cryptogenic stroke has worse prognosis than stroke by conventional mechanisms. However, the individual effects of intracranial atherosclerosis (ICAS) or atrial fibrillation (AF) on the prognosis of these patients have not been studied.AimsTherefore, we aimed to investigate the effects of ICAS and AF on the prognosis of ischemic stroke patients with active cancer.MethodsWe included ischemic stroke patients with active cancer between 2010 and 2020. Early neurological deterioration (END) was defined as an increase of ≥ 1 in the motor NIHSS score, or ≥ 2 in the total NIHSS score within 72 hours of admission. Unfavorable outcomes were defined as a score of ≥ 3 on the 3-month modified Rankin Scale.ResultsIn total, 116 ischemic stroke patients with active cancer were evaluated. In multivariable analysis, ICAS was positively associated with END (adjusted odds ratio [aOR] = 4.56, 95% confidence interval [CI]: 1.52–13.70), and this association showed a quantitative relationship according to the degree of stenosis of ICAS (stenosis group: aOR = 4.24, 95% CI: 1.31–13.72; occlusion group, aOR = 5.74, 95% CI: 1.05–31.30). ICAS was also closely related to unfavorable outcomes (aOR = 6.33, 95% CI: 1.15–34.79). In contrast, AF showed no significant association with END or unfavorable outcomes. Our data showed that patients with ICAS had larger and more severe initial stroke lesions, and poorer prognosis than those without.ConclusionsICAS, but not AF, was closely associated with poor prognosis in ischemic stroke patients with active cancer.

Abstract
Sjöberg, M, Eiken, O, Norrbrand, L, Berg, HE, and Gutierrez-Farewik, EM. Lumbar loads and muscle activity during flywheel and barbell leg exercises. J Strength Cond Res 37(1): 27–34, 2023—It is anticipated that flywheel-based leg resistance exercise will be implemented in future long-duration space missions, to counter deconditioning of weight-bearing bones and postural muscles. The aim was to examine low back loads and muscle engagements during flywheel leg press (FWLP) and flywheel squat (FWS) and, for comparisons, free-weight barbell back squat (BBS). Eight resistance-trained subjects performed 8 repetition maximums of FWLP, FWS, and BBS. Motion analysis and inverse dynamics-based musculoskeletal modeling were used to compute joint loads and muscle forces. Muscle activities were measured with electromyography (EMG). At the L4–L5 level, peak vertebral compression force was similarly high in all exercise modes, whereas peak vertebral posteroanterior shear force was greater (p < 0.05) in FWLP and BBS than in FWS. Among the back-extensor muscles, the erector spinae longissimus exerted the greatest peak force, with no difference between exercises. Peak force in the lumbar multifidus was lower (p < 0.05) during FWLP than during FWS and BBS. Peak EMG activity in the lumbar extensor muscles ranged between 31 and 122% of maximal voluntary isometric contraction across muscles and exercise modes, with the greatest levels in the lumbar multifidus. The vertebral compression forces and muscle activations during the flywheel exercises were sufficiently high to presume that when implementing such exercise in space countermeasure regimens, they may be capable of preventing muscle atrophy and vertebral demineralization in the lumbar region.

Abstract
The reduction of energy consumption is a major issue nowadays that should be considered during the design process. High-rise buildings represent a building type with significantly high energy consumption. They serve typically as offices with fully glazed façades, generating considerable energy demand. This study aims to optimize the envelope and the shading systems of a high-rise office building (Middle Europe). For this purpose, multiple façade variants were tested by assessing the thermal and visual comfort, as well as energy demand. The IDA ICE 4.8 building energy simulation program was used for thermal and lighting modeling and to carry out building physics calculations. Results revealed the best performing, optimized façade configuration in terms of comfort and energy efficiency.
The influence of calcium sulfate content on the hydration of belite-calcium sulfoaluminate cements with different clinker phase compositions

Published: November 2021

AbstractThe influence of different amounts of gypsum on the hydration of a belite-rich and a ye'elimite-rich belite-calcium sulfoaluminate clinker (BCSA) was investigated. The hydration kinetics, phase assemblages and compressive strength development of cements prepared using ye’elimite/ calcium sulfate molar ratios of 1, 1.5 and 2 were studied. Besides ettringite and monosulfate, aluminium hydroxide, strätlingite, C−S−H, iron-containing siliceous hydrogarnet and hydrotalcite were present as hydration products. Increasing the amount of gypsum increased the ratio of ettringite to monosulfate formed in the cement paste, lowered the amount of pore solution, delayed the dissolution of belite and ferrite, decreased the formation of strätlingite and, in the case of the ye’elimite-rich BCSA, led to an increase in compressive strength. Increased amounts of belite in the clinker led to the formation of higher quantities of C–S–H, at the expense of strätlingite and a lower compressive strength, as belite has a lower degree of reaction than ye’elimite and due to the formation of more C–S–H and strätlingite compared to the more space-filling ettringite. The thermodynamic model established for BCSA cement hydration agrees well with the experimental data. Compressive strength directly correlated with bound water from thermogravimetric analyses and inversely correlated with the porosity calculated from thermodynamic modelling.
Рождаемость в муниципальных образованиях России в 2011–2019 гг.
Authors: Петросян Артур Нельсонович 
Published: November 2021

Нехватка данных до недавнего времени определяла отсутствие работ, рассматривающих демографические показатели на уровне малых территорий для всех регионов Российской Федерации. Представленная статья посвящена анализу рождаемости в 2304 ячейках муниципального уровня субъектов РФ. Исследование базируется на данных муниципальной статистики Росстата о численности женщин репродуктивного возраста по пятилетним возрастным группам и числе родившихся. Для устранения влияния возрастной структуры на локальном (муниципальном) уровне были рассчитаны стандартизованные коэффициенты рождаемости в среднем за 2017–2019 гг. Расчёты базировались на методе косвенной стандартизации, в качестве стандарта выбрано население России.
Различия в уровне рождаемости сокращаются как на региональном, так и на муниципальном уровне за счёт продолжающегося снижения рождаемости для территорий, где её уровень по-прежнему высок. Однако расчёты показывают, что отношение коэффициента вариации на муниципальном уровне к аналогичному показателю для регионов возрастает: увеличивается роль местных факторов. При анализе динамики числа родившихся было обнаружено, что происходит стремительная концентрация рождений в региональных центрах (рост с 36,5 до 42,8% в 2011–2019 гг.). В то же время около половины прироста доли родившихся в центрах субъектов РФ обеспечено изменением правил регистрации рождений.
Соотношение общего и стандартизованного коэффициента призвано оценить вклад возрастной структуры женщин в уровень рождаемости. Из-за особенностей возрастного состава населения максимальная недооценка уровня рождаемости наблюдается в малых сельских муниципалитетах Европейского Севера и Поволжья. Различия оценочного коэффициента суммарной рождаемости (КСР) на муниципальном уровне позволяют более подробно описать распределение территорий по уровню воспроизводства населения. Только 10,6% населения России проживает на территориях, где оценка КСР выше уровня простого воспроизводства (2,15). Демографическая модернизация почти не оставила значительных (по численности населения) ареалов высокой рождаемости даже в регионах, где её уровень традиционно велик (Чечня, Дагестан, Ингушетия, Тува, Алтай).
Преждевременная мужская смертность и экономическое благосостояние домохозяйств
Authors: Кузнецова Полина Олеговна 
Published: November 2021

В работе на основе на данных Российского мониторинга экономического состояния и здоровья за 2001-2019 гг. (РМЭЗ) оценивается влияние смерти членов семьи, в том числе мужчин трудоспособного возраста, на благосостояние домохозяйств, в которых проживали умершие. Показано, что данные РМЭЗ, несмотря на определенную систематическую ошибку при регистрации смертей респондентов, могут быть использованы для оценки смертности мужчин и лиц трудоспособного возраста.
Показано, что в год смерти члена домохозяйства средние реальные подушевые доходы его семьи растут, т. е. эффект от снижения размера семьи оказывается сильнее эффекта от падения общих доходов. Дело в том, что экономические проблемы домохозяйства, связанные с потерей работоспособных членов семьи, начинаются не в год смерти, а заметно раньше. В связи с этим был рассмотрен более широкий временной диапазон, от 5 лет до смерти члена семьи до 5 лет после нее. Регрессионный анализ процессов попадания в бедность и выхода из нее показал, что смерть членов семьи оказывает негативное влияние на благосостояние других членов домохозяйства. В случае смерти мужчины трудоспособного возраста домохозяйства сталкиваются с повышенными рисками попадания в бедность в течение 1-5 лет до и после этого события.

Published: November 2021

Aim: To evaluate the effects produced by functional orthodontic appliances at dental and skeletal level in relation to the level of skeletal maturation in class II patients.
Study design: Longitudinal and observational study.
Patients selected for the study had been wearing Sander Bite Jumping Appliance (SBJA) for at least 12 months; they were first diagnosed (T1) with skeletal class II according to Ricketts’ cephalometric analysis, and had had lateral cephalograms taken before and after orthopaedic treatment (T2). Variables studied at T1 and T2 were: facial convexity, inclination of the upper and lower incisors, and facial depth. Results were compared between T1 and T2 for each variable and in relation to cervical maturation stage (CVS) according to the Lamparski analysis. Statistical analysis was performed using Shapiro–Wilk, t-student, Analysis of Variance (ANOVA) and multiple comparison tests, taking as statistically significant a p-value &lt;0.05.
Results: A final sample of 235 patients was obtained. Statistically significant differences were found in the inclination of the mandibular incisors between T1 and T2 and among the different cervical stages when the functional appliances were placed in CVS1 (p = 0.000), CVS2 (p = 0.04) or CVS5 (p = 0.048). For the remaining variables, significant differences were also found between T1 and T2, but these differences were similar in all cervical stages.
Conclusions: A significant proclination of the mandibular incisors was found when the functional appliance was placed during CVS1, CVS2, or CVS5. Time of placement of the functional appliances was not statistically significant for the remaining variables studied.

Authors: Jeyamani B. , Sowmiya B. 
Published: November 2021

Background: Though in recent years lower segment cesarian section (LSCS) procedure is the major reason for the reduction in the mortality rate for both mother and baby, inappropriate indications may affect the outcome of pregnancy. Thus, this study was done with the aim of assessing the prevalence of outcome of delivery among women who underwent caesarean section (CS) and to assess the factors associated with that outcome.Methods: This study was conducted with a sample of 98 pregnant mothers. After acquiring informed consent, those mothers who were indicated for CS (both elective and emergency) were enquired about the questionnaire containing two parts. Part one is about the history regarding previous birth and the next part is about age, parity, and outcome of current pregnancy (both mother and baby).Results: The mean age of the study participants is 27 years. Among the study participants, about half of them (51%) were in gravida one and 37 percent have one abortion. About four-fifths of the study participants (81%) were undergone elective LSCS. About one-fourth of the baby needs neonatal intensive care unit (NICU) admission and two percent have the complication of neonatal sepsis. The factors significantly associated with NICU admission of babies delivered after LSCS are more number of the previous history of abortions (p=0.004) and emergency LSCS (p=0.001) by using the chi-square test.Conclusions: The indication of previous LSCS for LSCS among pregnant mothers is in a rising trend that needs holistic commitment to reduce the prevalence of LSCS.

Estimates show that asthma is highly prevalent across the different communities, and recent reports showed that by 2015, 300 million patients will be affected by asthma, and projections show that additional 100 million individuals will furtherly be affected by 2025. Many factors can attribute to the development of asthma, including genetic, environmental, and allergic causes. They have essential roles in the pathogenesis and development of the condition. Exposure to the different environmental factors has been an area of research for a long time to identify the potential factors that can cause sensitization and asthma development, especially among children that are more exposed to these factors because of their physical structure and daily outdoor activities. In the present literature review, we aim to provide a thorough discussion about the allergic and environmental causes of asthma in children. Our evidence indicates that exposure to different environmental factors including indoor and outdoor pollutants can significantly increase the risk of asthma. Furthermore, maternal exposure to certain pollutants in the prenatal period was also reported to be significantly associated with developing asthma in children around the age of 5 years old. Exposure to these substances increases the inflammatory and airway reactions leading to the development of asthma. Accordingly, healthcare authorities should plan for adequate interventions to reduce the exposure to these compounds among children and reduce the risk of developing asthma and respiratory tract morbidities.

Święty Józef w religijności i tradycji ludowej w Polsce
Authors: Kupisiński Zdzisław 
Published: November 2021

Cześć oddawana świętym jest w swej istocie kultem Jedynego Boga i uwielbieniem go w dziełach, które uczynił w swoich świętych. Jest również formą wyrażenia wdzięczności Bogu za to, że pozwala ludziom na udział w swej świętości i doprowadza swoich wybranych do chwały nieba. Jednym ze świętych cieszących się szczególną czcią w Kościele jest św. Józef – mąż Maryi i opiekun Jezusa. W artykule autor stawia sobie za cel prezentację tej postaci na podstawie przekazów ewangelicznych, dokonuje także charakterystyki rozwoju kultu św. Józefa w Kościele oraz w religijności i tradycji ludowej. Do opracowania tematu skorzystał z literatury teologicznej, etnologicznej oraz własnych etnograficznych badań terenowych prowadzonych w subregionie opoczyńskim i radomskim (centralna Polska).
Kult św. Józefa dostrzega się nie tylko w liturgii Kościoła, gdzie jego główne święta obchodzone są 19 marca i 1 maja, ale także w religijności ludowej. Cześć oddawana temu świętemu przejawia się w nabożeństwach ku jego czci, pieśniach, modlitwach, w licznych obrazach z jego wizerunkiem umieszczanych w domach oraz przydrożnych kapliczkach. Św. Józef wielokrotnie obierany jest za patrona kościołów, miejscowości, zawodów, uznawany jest także za opiekuna ojców oraz patrona dobrej śmierci. Jego kult jest żywy również w czasach współczesnych, a przez wstawiennictwo tegoż świętego u Boga wiele osób otrzymuje wypraszane łaski.
