Problematic Facebook use behavior and locus of control in physiotherapy students
Authors: Salik Sengul Yesim , Kahraman Turhan , Ozcan Kahraman Buse 
Published: August 2021

AbstractBackgroundProblematic Facebook use is a broader umbrella for term addictive-like symptoms, and scarce self-regulation related to Facebook use reflecting social and personal problems, and many studies have suggested that it is associated with many psychosocial problems. Locus of control (LOC) is described as a personality trait developed through social learning theory. Recently, LOC has got attention from both the patient’s and clinician’s perspectives. In addition, higher external LOC is associated with problematic Internet use. The aim was to investigate whether problematic Facebook use is associated with LOC. Four hundred twenty-one university students were enrolled in this cross-sectional study. Problematic Facebook use was determined by the Bergen Facebook Addiction Scale, and the participants were divided into two groups as neutral users and problematic users. Locus of control was assessed using the Locus of Control Scale, including subscales of personal control, belief in chance, the meaninglessness of the effortfulness, belief in fate, and belief in an unjust world.ResultsIn total, 333 students were eligible for the study. There were 66 students with neutral Facebook use (19.8%), and the remaining (n=267) had problematic Facebook use (80.2%). No significant difference was observed in the demographic characteristic of neutral and problematic Facebook users (p>0.05). Problematic Facebook users had significantly higher scores on the meaninglessness of the effortfulness (p<0.001), belief in fate (p=0.019), and belief in an unjust world (p=0.004) compared to the neutral Facebook users.ConclusionsThe results showed that the physiotherapy students having a problematic Facebook had significantly higher scores on the meaninglessness of the effortfulness, belief in fate, and belief in an unjust world compared to neutral Facebook users. All these negative thoughts might be a problem both for students themselves and their future patients.
Interrelationships Among Fertility, Internal Migration,and Proximity to Nonresident Family:A Multilevel Multiprocess Analysis
Authors: Thomas Michael J. , Dommermuth Lars 
Published: August 2021

AbstractPast research has found that relations to nonresident family can influence individual fertility and migration behaviors separately. However, fertility and migration outcomes may also be interrelated, suggesting potential links across all three demographic processes. With this in mind, we track a cohort of women in Norway from age 18 to 31, recording the emergence of birth and migration events as well as their proximity to nonresident family networks (siblings and parents). Using a multilevel multiprocess statistical framework, with observations nested within women and equations for births, migrations, and proximity to nonresident family estimated simultaneously, our results support the notion that linked lives matter. Even in early adulthood, proximity to nonresident family has a positive effect on transitions to motherhood, whereas the presence of children (itself an outcome of past fertility) is associated with lower propensities to migrate. Mothers also have higher propensities to be living near family than women without children. The presence of local nonresident family reduces propensities for second and third migrations. However, after accounting for unobserved heterogeneity and selection, we observe a small positive effect of proximity to family on first migrations undertaken after age 18. Significant cross-process residual correlations exist across all three outcomes, suggesting that separately estimated model estimates may be vulnerable to bias emerging from unobserved sources of heterogeneity and selection. Our analysis therefore suggests that decisions about fertility, migration, and proximity to family are jointly determined and endogenous, and they should be analyzed simultaneously when possible.

Published: August 2021

Background : This research aimed to examine and analyze risk factors for death, hematologic parameters and coagulation in COVID-19 patients at RSUD Dr. Soetomo Surabaya, one of the referral centers for probable COVID-19 patient cases in East Java. Method : This was a retrospective analytical study by taking secondary data on patients with probable COVID-19 cases who were treated in hospital isolation rooms from May to September, 2020. Result : Of 538 probable COVID-19 patients, 217 tested positive, with an average age of 52.11±13.12 years, and there were 38 death cases. Hematologic parameters, such as white blood cell, neutrophil and lymphocyte counts, were significantly different in the deceased group. On the other hand, coagulation parameters, consisting of D-dimer, CRP, PT, and aPTT showed significantly similar value in the deceased group. Univatiate analysis concluded that chronic kidney disease, diabetes mellitus, coronary heart disease, WBC, NLR, and PPT counts could predict the mortality, while multivariate analysis revealed that coronary heart disease was the only significant independent predictor of mortality. Conclusion : This research shows that hematologic and coagulation parameters were increased in the majority of COVID-19 patients and the deceased group. While the number of neutrophils and WBC increases, the number of lymphocytes decreases significantly with increasing disease severity. Coronary heart disease is an independent predictor of mortality.

Published: August 2021

Background: Non-communicable diseases, the major cause of death and disability, are susceptible to modifiable and non-modifiable risk factors. Atrial fibrillation (AF) increases the risk of stroke by 4-5 times and can lead to cardiovascular mortality. This study was conducted to assess the effects of different sociodemographic factors on stroke development in patients with AF. Methods: A cross-sectional study was conducted between January and June 2018 on patients recruited from Lebanese community pharmacies. The CHA2DS2-VASc scoring system is utilized as a stroke risk stratification tool in AF patients. Participants with a previous physician diagnosis of AF, documented on medical records, were included in this study. Results: A total of 524 patients were enrolled in the study with a mean age of 58.75 (± SD) ± 13.59 years with hypertension (78.38%) being the most predominant disease. The results showed that obesity (Beta=0.610, p-value =0.011), retirement and unemployment compared to employment (Beta=1.440 and 1.440, p-value=0.001 respectively), divorced/widow compared to married (Beta=1.380, p-value =0.001) were significantly associated with higher CHA2DS2-VASc scores whereas high versus low socio-economic status (Beta=-1.030, p=0.009) and high school education versus primary education level (Beta=-0.490, p-value=0.025) were significantly associated with lower CHA2DS2-VASc scores. Conclusions: The study highlights that the CHA2DS2-VASc score is affected by the presence of various sociodemographic and socioeconomic characteristics in patients with AF. Thus, screening for those factors may predict the progression of cardiovascular disease and may provide an optimal intervention.

Published: August 2021

Background: In developing countries, pregnancy and childbirth are the leading causes of death among women. In this context, family planning and access to contraceptives are crucial for reducing pregnancy-related morbidity and mortality. Therefore, we aimed to look into the trends of contraception and determinants of contraceptive use in Pakistan. Methods: This study used data for women of reproductive age from four Pakistan Demographic and Health Surveys datasets. Contraception was the outcome variable, whereas, women’s and partner’s education, occupation, wealth quintile, region, place of residence, and exposure to family planning messages were the explanatory variables. Pooled prevalence was estimated using SUMARI and regression analysis was undertaken using SPSS to produce an adjusted prevalence ratio with 95% confidence intervals. Results: Data of 40,259 ever-married women of reproductive age (EMWRA) was analysed. Of the total EMWRA, 30% were using contraception. Of these, 26% were using traditional methods and 74% were using modern methods. The most common method of contraception was condoms (30.5%). The pooled prevalence of contraception used was 29.5% (95% CI 29.1 to 30.0). Through multivariate analysis, women's age, place of residence, region, wealth index, women’s education, their working status, and exposure to family planning messages were found to be significant determinants of contraception usage. Conclusions: There is a noticeable gap regarding awareness and uptake of contraception leading to low contraceptive use among women in Pakistan. In the light of our results, it is important to highlight the importance of girl’s education for building awareness and empowerment.
Student experiences of a return to practice programme: a qualitative study
Authors: Coates Maggie , Macfadyen Ann 
Published: August 2021

Background: Nurses, midwives and other health professionals who return to practice come from a range of backgrounds and return for a variety of reasons. Much of the research on return to practice concerns programme provision rather than returnee experience. Aim: This qualitative study focused on the experiences of nursing, midwifery and allied health students undertaking a return to practice programme at a higher education institute. It interpreted the perceptions of the student experience of returning to clinical practice following a lapse in professional registration. Methods: Data collection methods were qualitative and involved focus groups. Findings were analysed using thematic analysis. Findings: Several themes and subthemes emerged from the data, including ‘the importance of returnee identity’ and ‘challenges and barriers’. Findings demonstrated different approaches to and influences on returnees' learning journeys. Conclusion: Previous knowledge, skills and experience were often hidden from view and hard to explain although crucial to returnee success.

Nonlinear pulse post-compression represents an efficient method for
ultrashort, high-quality laser pulse production. The temporal pulse
quality is, however, limited by amplitude and phase modulations
intrinsic to post-compression. We here characterize in frequency and
time domain with high dynamic range individual post-compressed pulses
within laser bursts comprising 100-kHz-rate pulse trains. We
spectrally broaden 730 fs, 3.2 mJ pulses from a Yb:YAG laser in a
gas-filled multi-pass cell and post-compress them to 56 fs. The pulses
exhibit a nearly constant energy content of 78% in the main peak over
the burst plateau, which is close to the theoretical limit. Our
results demonstrate attractive pulse characteristics, making
multi-pass post-compressed lasers very applicable for pump–probe
spectroscopy at, e.g., free-electron lasers or as efficient drivers
for secondary frequency conversion stages.

Nitrogen-vacancy color centers (NVs) in diamond have several potential applications ranging from quantum computing to data storage. However, artificial NVs are often close to the surface, which limits their spatial density and applicability. Here we demonstrate an effective and precise method for preparing deep single NVs in diamond. The method is based on a spatial-shaped femtosecond laser to overcome laser defocus in high-refractive materials, and realizes the preparation of single NVs at 95 µm. In addition, owing to the good energy distribution of the shaped laser focus, the single NVs exhibit a statistic yield of

-cladded Si lattice-shifted photonic crystal waveguides via machine learning and found a structure that generates low-dispersion slow light with a group index of approximately 20 in the full C-band at telecom wavelengths. The normalized delay-bandwidth product is as large as 0.45, which is close to the theoretical upper limit. The transition structure between this waveguide and a Si-channel waveguide was designed using an evolutional optimization, and a C-band average loss of 0.116 dB/transition was calculated. These results prove the possibility of further enhancing the versatility of slow light.
Risk for short-term undesirable outcomes in older emergency department users: Results of the ER2 observational cohort study
Authors: Launay Cyrille P. , Galery Kevin , Vilcocq Christine , Afilalo Marc , Beauchet Olivier 
Published: August 2021

Background
The "Emergency Room Evaluation and Recommendations" (ER2) is a clinical tool designed to determine prognosis for the short-term Emergency Department (ED) undesirable outcomes including long length of stay (LOS) in ED and in hospital, as well as the likelihood of hospital admission during an index ED visit. It is also designed to guide appropriate and timely tailor-made geriatric interventions. This study aimed to examine whether ER2 assessment part was: 1) usable by ED healthcare workers (e.g. nurses) and 2) scoring system associated with long LOS in ED and in hospital, as well as hospital admission in older ED users on stretchers.

Methods
Based on an observational, prospective and longitudinal cohort study 1,800 participants visiting the ED of the Jewish General Hospital (Montreal, Quebec, Canada) were recruited between September and December 2017. ER2 assessment determined three risk-levels (i.e., low, medium and high) for short-term ED undesirable outcomes. The rate of ER2 digital form completed, the time to fill ER2 items and obtain ER2 risk-levels, the LOS in ED and in hospital, and hospital admission were used as outcomes.

Results
ER2 was usable by ED nurses in charge of older ED users. High-risk group was associated with both increased ED stay (coefficient of regression β = 3.81 with P≤0.001) and hospital stay (coefficient of regression β = 4.60 with P = 0.002) as well as with hospital admission (HR = 1.32 with P≤0.001) when low ER2 risk level was used as referent level. Kaplan-Meier distributions showed that the three risk groups of participants differed significantly (P = 0.001). Those with high-risk level (P≤0.001) were discharged later from hospital to a non-hospital location compared to those with low risk. There was no significant difference between those classified in low-risk and in medium-risk groups (P = 0.985) and those in medium and high-risk groups (P = 0.096).

Conclusion
The ER2 assessment part is usable in daily practice of ED care and its risk stratifications may be used to predict adverse outcomes including prolonged LOS in ED and in hospital as well as hospital admission.

Background
Gastric intestinal metaplasia (IM) can lead to gastric cancer. Until now, there have been limited studies of predictors for regression and progression of IM. This study aimed to determine risk factors associated with regression or progression of IM for guiding proper management and prevention of gastric cancer.

Methods
2,025 patients undergoing gastroscopy in Thammasat University Hospital, Thailand were enrolled during September 2017-August 2019. Patients’ data including baseline characteristics, laboratory results, and histopathology of gastric biopsies from University medical database were extensively reviewed.

Results
2,025 patients had mean age of 61.3 years and 44.2% were males. Overall H. pylori prevalence was 47.5%. There were 1,551(76.6%) patients with chronic gastritis and 361(17.8%) with IM. Of 400 patients with chronic gastritis having follow-up endoscopy and repeated gastric biopsies, 104(26%) had persistent H. pylori infection and 27(26%) developed IM during mean follow-up time of 24 months. Persistent H. pylori infection was significantly associated with development of IM (OR 3.16, 95%CI 1.56–6.39, p = 0.001). Regression, persistence, and progression of IM were demonstrated in 57.3%, 39.2%, and 3.5% of patients, respectively. Age >65 years, persistent H. pylori infection, and diabetes mellitus were significantly associated with persistent IM or progression to dysplasia with OR 2.47(95%CI 1.33–4.61, p = 0.004), OR 2.64(95%CI 1.13–6.18, p = 0.025), and OR 2.54(95%CI 1.16–5.54, p = 0.019), respectively. Patients without H. pylori infection had more IM regression than patients with persistent infection (60.4%vs.39.4%, p = 0.035). Patients with persistent H. pylori infection significantly had higher IM progression to dysplasia (15.2%vs.2.1%; OR 11.15, 95%CI 1.18–105.24, p = 0.035) than noninfected. During 24 months of study, 30 patients (1.5%) were diagnosed with gastric cancer.

Conclusion
Regression of IM could be achieved by successful H. pylori eradication. Persistent H. pylori infection was significantly associated with development and progression of IM to dysplasia. Age >65 years and diabetes mellitus were also significant predictors for IM progression.

Published: August 2021

BackgroundCervical radiculopathy is a relatively common and disabling condition involving local pain in the neck region and pain that radiates into the upper limb. Recent data suggest that cervical traction may effectively reduce disability and pain, with a dose-response relationship. The main aim of this study was therefore to evaluate the mid-term effect of an intensive cervical traction protocol for patients with cervical radiculopathy on disability, and to compare the effects with those reported by non-intensive protocols in the literature.MethodsWe conducted a prospective open observational study of 36 patients referred by their general practitioner for symptoms suggestive of cervical radiculopathy. All patients underwent the same treatment: a 30-minute cervical traction protocol, twice a day, for five consecutive days. The main objective was the evaluation of disability at 3 months. We evaluated at baseline (D1), the end of the protocol (D5) and at mid-term (M3) disability, cervical pain, radiating pain, pain on motor imagery, presence of neuropathic pain and medication consumption. The primary outcome was the proportion of patients for whom the Neck Disability Index improved by more than the minimum clinically important difference of 7 points by M3.ResultsThirty-six patients were included in this study. The Neck Disability Index improved by more than the minimum clinically important difference in 48.3% at M3. Mean Neck Disability Index (p < .001), mean cervical VAS (p < .001), mean radiating VAS (p < .001), and mean VAS for imagined lateral flexion and rotation (p < .002) improved significantly from D1 to D5 and from D1 to M3. Consumption of medication reduced at each time point. The proportion of patients with neuropathic pain reduced from 61.1% at D1 to 33.3% at D5 and 48.3% at M3.ConclusionDisability reduced by more than the minimum clinically important difference in almost half of the participants following the intensive traction protocol. These results are encouraging and suggest that this complex condition can be treated with relatively simple methods.
