Relationship of smartphone use severity with sleep quality, depression, and anxiety in university students

Background and aims The usage of smartphones has increased rapidly in recent years, and this has brought about addiction. The aim of the current study was to investigate the relationship between smartphone use severity and sleep quality, depression, and anxiety in university students. Methods In total, 319 university students (203 females and 116 males; mean age = 20.5 ± 2.45) were included in the study. Participants were divided into the following three groups: a smartphone non-user group (n = 71, 22.3%), a low smartphone use group (n = 121, 37.9%), and a high smartphone use group (n = 127, 39.8%). All participants were evaluated using the Pittsburgh Sleep Quality Index, Beck Depression Inventory, Beck Anxiety Inventory; moreover, participants other than those in the smartphone non-user group were also assessed with the Smartphone Addiction Scale. Results The findings revealed that the Smartphone Addiction Scale scores of females were significantly higher than those of males. Depression, anxiety, and daytime dysfunction scores were higher in the high smartphone use group than in the low smartphone use group. Positive correlations were found between the Smartphone Addiction Scale scores and depression levels, anxiety levels, and some sleep quality scores. Conclusions The results indicate that depression, anxiety, and sleep quality may be associated with smartphone overuse. Such overuse may lead to depression and/or anxiety, which can in turn result in sleep problems. University students with high depression and anxiety scores should be carefully monitored for smartphone addiction

A rare consequence of trauma: Chylothorax

Chylothorax is defined as the lymphatic fluid accumulation in the pleural space due to the obstruction or injuries in the ductus thoracicus. The incidence of chylothorax due to blunt and penetrating traumas is low at a rate of 0.2-3%. This case presentation intends to evoke chylothorax as a rare cause of pleural effusion due to injuries. A 27-day-old infant was brought to the emergency department with the complaint of a sudden respiratory distress developing after falling off the couch. The respiratory rate was 62, the pulse rate was 174, and the oxygen saturation rate was 68%. In the physical examination, the respiratory sounds were diminished bilaterally. The patient was intubated. As the saturation levels did not improve after intubation, a needle aspiration was performed bilaterally in the anterior axillary line with a prediagnosis of massive haemothorax. A yellowish fluid was aspirated from the pleural space bilaterally. Chest tubes were inserted bilaterally to treat respiratory distress due to mass effect of chylothorax. Massive chylothorax cases may result in serious complications leading to respiratory distress and cardiac dysfunction. An early diagnosis and appropriate treatment can be life-saving in these patient

Mothers\u27 Perceptions of Their Children\u27s Weight: Opportunity for Health Promotion in Kuwait

Background: Mothers’ perceptions of their children’s weight remain mostly unknown in oil-rich countries of the Middle East. Aims: To compare maternal perceptions of their children’s weight with actual body weight. Methods: We used the Kuwait nutritional surveillance data for 5 consecutive years (2015-2019) (N = 5119), which were collected through face-to-face interviews with mothers of children aged 2-5 years attending vaccination centres. Results: Of the 5119 mothers in the study, 163 (3.18%) and 332 (6.48%) had obese or overweight children, respectively. Among 4624 mothers who had normal weight children, 1350 (29.20%) perceived their children’s weight as below normal. Seventy-nine (48.47%) and 16 (9.82%) mothers of children with obesity thought their children had normal weight or were underweight, respectively. Conclusion: Mothers in Kuwait often underestimate the weight of their children, including those children who have normal weight. This highlights the importance of addressing maternal misperceptions during visits to the primary healthcare centre

Multiple Systemic Infarctions as a Complication of Bronchial Artery Embolization With Polyvinyl Alcohol: A Case Report

Bronchial artery embolization (BAE) is a widely used modality of treatment for massive hemoptysis which has well known complications such as chest pain, groin hematoma and transverse myelitis but systemic embolization of the material used in the procedure is very rare and was reported only four times in the literature which were all caused by the use of microspheres. Herein we report a case of a 41-year-old caucasian male who had a history of tuberculosis 10 years ago. He had BAE with polyvinyl alcohol (PVA) for the treatment of recurrent hemoptysis. After the procedure, the patient complained of severe pain on the left upper quadrant and bilateral costovertebral regions and in abdominal CT, multiple infarcts in the subcapsular area of the spleen and kidneys were observed. This is the first reported case of inadvertent systemic embolization secondary to BAE with PVA. Although the risk of systemic embolization is greater with microspheres, still potentially serious and life threatening complications may occur with PVA

Obesity During Adolescence and Feeding Practices During Infancy: Cross-Sectional Study

Background: Breastfeeding is proposed to play a role in reducing the risk of obesity throughout life. Kuwait has an extremely high prevalence of childhood obesity (45% of adolescents are overweight/obese) and extremely low breastfeeding indicators, particularly exclusive breastfeeding. In fact, little is known about the association between breastfeeding and obesity from Kuwait and the broader Middle East. Aims: To estimate the prevalence of overweight/obesity in female adolescents in Kuwait and assess its association with breastfeeding during infancy. Methods: This is a cross-sectional study that included 775 girls randomly selected from public and private high schools in Kuwait. The primary exposure was breastfeeding in the first four months of life, and the outcome was overweight/obesity during adolescence. Multivariable logistic regression was used to assess the association between breastfeeding and overweight/obesity while adjusting for potential confounders. Results: Approximately 45% of adolescent girls were either overweight/obese. We found no significant association between breastfeeding (exclusive/mixed breastfeeding and formula feeding/no breastfeeding) and overweight/obesity neither in univariable analysis (Crude Prevalence Ratio: 1.14, 95%CI [0.92–1.36] & Crude Prevalence Ratio: 1.29, 95%CI [0.86–1.68]; p = 0.293) for mixed feeding and no breastfeeding respectively, nor in multivariable analysis (Adjusted Prevalence Ratio: 1.14, 95%CI [0.85–1.42] & Adjusted Prevalence Ratio: 1.20, 95%CI [0.68–1.68]; p = 0.589) for mixed feeding and no breastfeeding respectively. Conclusion: Breastfeeding during infancy was not significantly associated with overweight/obesity during adolescence. However, breastfeeding should be encouraged for its indisputable benefits for infants and their mothers alike. Further prospective studies are needed to assess the association

Magnetic resonance imaging study of corpus callosum abnormalities in patients with different subtypes of schizophrenia

Background. Reductions in the size of the corpus callosum (CC) have been described for schizophrenia patients, but little is known about the possible regional differences in schizophrenia subtypes (paranoid, disorganised, undifferentiated, residual).  Methods. We recruited 58 chronically schizophrenic patients with different subtypes, and 31 age-and-gender matched healthy controls. The callosum was extracted from a midsagittal slice from T1 weighted magnetic resonance images, and areas of the total CC, its five subregions, CC length and total brain volume were compared between schizophrenia subtypes and controls. Five subregions were approximately matched to fibre pathways from cortical regions.  Results. Schizophrenia patients had reduced CC total area and length when compared with controls. Disorganised and undifferentiated schizophrenics had a smaller prefrontal area, while there was no significant difference for the paranoid and residual groups. The premotor/supplementary motor area was smaller in all schizophrenia subtypes. The motor area was smaller only in the disorganised group. A smaller sensory area was found in all subtypes except the residual group. Parietal, temporal and occipital areas were smaller in the paranoid and undifferentiated groups. Total brain volume was smaller in all schizophrenia subtypes compared with controls, but did not reach statistical significance.  Conclusion. These findings suggest that the heterogeneity of symptoms may lead to the different CC morphological characteristics in schizophrenia subtypes

Time Trends of Overweight and Obesity Among Schoolchildren in Kuwait Over a 13-Year Period (2007-2019): Repeated Cross-Sectional Study

Objectives: This study aimed to examine age-specific trends in the prevalence of overweight and obesity in schoolchildren in Kuwait over a 13-year period (2007 to 2019) using the World Health Organization (WHO), the Centers for Disease Control and Prevention (CDC) and the International Obesity Taskforce (IOTF) definitions. Design: Using cross-sectional approach, Kuwait Nutrition Surveillance System (KNSS) objectively measured weight and height of schoolchildren over a 13-year period. Log-binomial regression models were used to examine age-specific trends of obesity and overweight over the study period. Setting: Public primary, middle, and high schools in all provinces of Kuwait. Participants: Schoolchildren aged 5-19 years (n 172 603). Results: According to the WHO definition, the prevalence of overweight and obesity in schoolchildren respectively increased from 17.73% and 21.37% in 2007 to 20.19% and 28.39% in 2019 (P for trend\u3c0.001). There is evidence that the obesity in females (but not males) has levelled off in the period 2014-2019 according to the three definitions of obesity, which is corroborated by a similar trend in the mean of BMI-for-age Z score. Conclusion: The prevalence of obesity and overweight in schoolchildren in Kuwait has risen over the last 13 years and trends are similar across all definitions. Obesity is no longer increasing at the same pace and there is evidence that the prevalence of obesity in females has plateaued. The current level of childhood overweight and obesity is too high and requires community-based and school-based interventions

“The Lolelaplap (Marshall Islands) in Us: Sailing West to East (Ralik→Ratak) to These Our Atolls (Aelon Kein Ad) Ad Jolet Jen Anij (Our Blessed Inheritance from God)”

This paper discusses the expansion of Oceania through a Marshallese indigenous lens as a focal point. It explains that decolonizing methodologies allows reclaiming of space for mental liberation and reassurement of constitutional rights. It highlights similar occurrences of decolonization practices meeting resistance in the 21st century all while strengthening the human right argument that no human deserves any less than their fellow human brothers and sisters. It argues that an indigenous imagery can only be viewed through an indigenous lens where the researches’ level of purity is retained and unfiltered. It nevertheless argues that Marshallese ethnolinguistics reveal the same cultural practices in America, Judeo-Christianity, and Oceania thus dictating the reality that “we are the same not withstanding one stays here and one there (Bedbedjin Bedbedjen, Bedbedjinma wot Kwe)”. It further explains the importance in these similarities and how Marshallese spirituality predates introduced American Judeo-Christianity despite the latter attempting to marginalize the former. It concludes by stating that Marshallese contributions on the global stage are rooted in that culture of love (IaKwe) which is echoed by the custom(s) revealing the significance of Marshallese validation academically, spiritually, economically, & socially to prevent institutionalized discrimination. This paper ends stating that the agency to know one’s self and how one should fit in the world, is a human right in itself and Marshallese are entitled to this sense of self worth through knowing thy self by thy self where real thinking takes place in one’s own mind as we all live our own lives

Measurement of double-parton scattering in inclusive production of four jets with low transverse momentum in proton-proton collisions at s \sqrt{s} = 13 TeV

A measurement of inclusive four-jet production in proton-proton collisions at a center-of-mass energy of 13 TeV is presented. The transverse momenta of jets within |η| < 4.7 are required to exceed 35, 30, 25, and 20 GeV for the first-, second-, third-, and fourth-leading jet, respectively. Differential cross sections are measured as functions of the jet transverse momentum, jet pseudorapidity, and several other observables that describe the angular correlations between the jets. The measured distributions show sensitivity to different aspects of the underlying event, parton shower modeling, and matrix element calculations. In particular, the interplay between angular correlations caused by parton shower and double-parton scattering contributions is shown to be important. The double-parton scattering contribution is extracted by means of a template fit to the data, using distributions for single-parton scattering obtained from Monte Carlo event generators and a double-parton scattering distribution constructed from inclusive single-jet events in data. The effective double-parton scattering cross section is calculated and discussed in view of previous measurements and of its dependence on the models used to describe the single- parton scattering background

Measurements of the pp → W±^{±}γγ and pp → Zγγ cross sections at s\sqrt{s} = 13 TeV and limits on anomalous quartic gauge couplings

The cross section for W or Z boson production in association with two photons is measured in proton-proton collisions at a centre-of-mass energy of 13 TeV. The data set corresponds to an integrated luminosity of 137 fb$^{-1}$ collected by the CMS experiment at the LHC. The W → ℓν and Z → ℓℓ decay modes (where ℓ = e, μ) are used to extract the Wγγ and Zγγ cross sections in a phase space defined by electron (muon) with transverse momentum larger than 30 GeV and photon transverse momentum larger than 20 GeV. All leptons and photons are required to have absolute pseudorapidity smaller than 2.5. The measured cross sections in this phase space are σ(Wγγ) = 13.6$^{+1.9}$$_{−1.9}$(stat)$^{+4.0}$$_{−4.0}$(syst) ± 0.08 (PDF + scale) fb and σ(Zγγ) = 5.41$^{+0.58}$$_{−0.55}$(stat)$^{+0.64}$$_{−.070}$(syst) ± 0.06 (PDF + scale) fb. Limits on anomalous quartic gauge couplings are set in the framework of an effective field theory with dimension-8 operators
