Abstract
Background: The cross-body and the modified sleeper stretch have been used to improve posterior shoulder soft tissue flexibility and to increase glenohumeral joint internal rotation (GHJ IR) in overhead athletes. However, due to the inability to stabilize patient’s scapula and control GHJ rotation with the cross-body stretch and the potential for subacromial impingement or symptoms’ aggravation with the modified sleeper stretch, a new stretching technique was developed as an alternative to these commonly used stretches that may allow for greater stability of the scapula without reproducing symptoms, as well as providing an inhibition component to the posterior shoulder girdle muscles. Thus, the current study aimed to examine and compare a novel stretching technique to the traditional modified sleeper stretch to determine the effect on glenohumeral IR range of motion (ROM), self-reported pain, and subject satisfaction in overhead athletes with glenohumeral internal rotation deficits (GIRD). Methods: Forty-two overhead athletes with GIRD [mean age 25.9 ± 2.6 years, 20 males and 22 females] participated in this study. Participants were randomly assigned into either novel stretching group or modified sleeper stretching group. IR ROM was measured with a digital inclinometer, pain was measured with Numeric Pain Rating Scale, and subject satisfaction level was measured by a 6-item questionnaire developed and validated by the study’s authors. Outcomes were measured before, immediately, and at week 4 post intervention. Results: There was no significant group by time interaction effect for IR ROM (p=0.27); however, there was a significant change over time (p<0.001, η2=0.77). Both groups demonstrated a significant increase in IR from baseline to immediate and week 4, and from immediate to week 4 (p<0.001). There was also a significant reduction in pain intensity over time for the novel group (p=0.016, r=0.6) compared to the traditional group (p=0.080). For the satisfaction level, only the easiness of performance was significantly different and in favor of the traditional group (p=0.020, r=0.5) following the 4 weeks of the stretching protocols. Conclusion: Both stretches appear to be effective at improving IR ROM in overhead athletes with GIRD. However, the novel stretching is more effective at reducing shoulder pain and thus might be more appropriate for symptomatic patients.

Abstract
Background: Endometriosis have a negative influence on women’s sexual life. The aim of the current study was to test a conceptual model considering the interrelated role of anxiety, depression, sleep quality, physical activity, BMI, stage of endometriosis, the intensity of dyspareunia and pelvic pain on sexual function (SF) in infertile women with endometriosis. Also test the mediating role of sleep quality, anxiety, and depression.Method: In the present cross-sectional study, 220 infertile women with a laparoscopically confirmed endometriosis were recruited. Data were collected using a socio-demographic checklist, Female Sexual Function Index (FSFI), Pittsburgh Sleep Quality Index (PSQI), Hospital Anxiety and Depression Scale (HADS), Visual Analog Scale (VAS). Results: We found that anxiety, depression, sleep quality, BMI, level of education, stage of endometriosis, and dyspareunia have a direct effect on women’s SF. In our study, sleep quality, anxiety, pelvic pain, and depression were the four major mediators that the higher scores lead to a decrease in the SF of endometriosis patients. The intensity of pelvic pain with an effect on sleep quality (SQ) and dyspareunia change women’s SF. The lower level of physical activity, and higher BMI with indirect effect thorough anxiety, and SQ can worsen SF. Also, a higher level of anxiety leads to poor SQ and depression. Anxiety with both direct and indirect effect impress women’s SF.Conclusion: It seems that the main risk factors for sexual dysfunction in women with endometriosis are higher rates of anxiety, depression, poor sleep quality, pelvic pain, and dyspareunia. In the care of women with endometriosis, not only laparoscopy and medical treatment should be performed but also psychotherapeutic and psychosexual help should be offered.

Abstract
Background: Studies indicate that health-related components of physical fitness are associated with mental health outcomes. However, research is scarce concerning this relationship in young adolescents in general and non-existent in Norwegian populations specifically. The aim of the study was to examine whether body composition, muscular strength and cardiorespiratory fitness were associated with self-reported mental health in Norwegian adolescents. Methods: Adolescents from four regions of Norway (n = 1486; mean age = 13.9; girls = 50.6%) participated. Self-reported mental health (psychological difficulties) was measured by completing the Strengths and Difficulties Questionnaire. Objective measures were taken of their cardiorespiratory fitness, muscular strength and body composition. Linear mixed effects models were conducted to assess the associations between the health-related components of physical fitness and psychological difficulties. Results: Body composition was not associated with psychological difficulties. Muscular strength independently was associated with psychological difficulties, but when all independent variables were entered in the fully adjusted model, only cardiorespiratory fitness was associated with psychological difficulties. School clusters were included as random effects and all models were controlled for sex, socioeconomic status and birthplace (domestic or foreign). Conclusions: There was a small but significant inverse association between higher cardiorespiratory fitness and lower levels of psychological difficulties in Norwegian adolescents. The results suggest that muscular strength is not associated with psychological difficulties in adolescents, when controlling for cardiorespiratory fitness. Future research on how exercise affects mental health outcomes should investigate whether there is a greater effect for those who improve their cardiorespiratory fitness, compared to those who improve other components of fitness.

Abstract
Background: Although some studies have reported the association between life negative events and depressive disorders, very limited studies have examined the association between life negative events exposure and depressive symptoms risk among Chinese older adults. Methods : Data were obtained from the China Longitudinal Ageing Social Survey (CLASS), which was a stratified, multi-stage, probabilistic sampling survey, conducted in 2014. General linear regression and logistic regression were used to examine the association between life negative events exposure and depressive symptoms among Chinese older adults. Results: Life negative events showed statistical dose-response association with depressive symptoms risk after adjustment for the confounding factors ( P trend <0.001). Under consideration of life negative events exposure, participants who lived in rural areas, without a spouse or live alone were vulnerable to depressive symptoms. Conclusions: Life negative events played a risk role of depressive symptoms among Chinese older adults, especially among those in rural areas, females or without a spouse. Our current study is valuable for the development of special prevention depressive symptoms programs among elderly individuals, especially those who have experienced negative events.

Abstract
Background: Despite the fact that, in itself, emergency midline laparotomy is a factor risk for an incisional hernia, active research on hernia prevention in emergency settings is lacking. Different kinds of meshes and mesh positions have been studied in elective abdominal surgery, but no randomized controlled trials in emergency settings have been published.Methods: The PREEMER trial is a multicenter, double-blinded, randomized controlled trial to be conducted in seven hospitals in Finland (Oulu, Helsinki, Tampere, and Turku university hospitals and Jyväskylä, Lahti, and Seinäjoki non-university hospitals). A total of 244 patients will be randomized at a 1:1 ratio to either the retrorectus mesh group, featuring a self-gripping prophylactic mesh, or to the no mesh (control) group, both closed by small stitch 4:1 closure with continuous slowly absorbable monofilament suturing. The primary outcome of the PREEMER trial is the incisional hernia incidence two years after surgery, which will be detected clinically and/or radiologically. Secondary outcomes are the Comprehensive Complication Index score, incidence of surgical site infections and fascial dehiscence within 30 days of surgery; the incisional hernia repair rate and mesh- or hernia-related re-operations within the two- and five-year follow-ups; the incidence of incisional hernia within the five-year follow-up; and quality of life measured by RAND-36, the Activities Assessment Scale (AAS), and the PROMIS-questionnaire within 30 days and two and five years from surgery. Additionally, medico-economic explorative measures are analyzed.Discussion: The PREEMER Trial will provide level 1 evidence on incisional hernia prevention in an emergency setting.Trial registration: Clinical Trials NCT04311788https://register.clinicaltrials.gov/prs/app/action/SelectProtocol?sid=S0009MXF&selectaction=Edit&uid=U0003YIA&ts=2&cx=7ef75k.

Published: April 2020

Abstract
Background: Chinese domestic pig breeds are reputed for pork quality, but their low ratio of lean-to-fat carcass weight decreases production efficiency. A better understanding of the genetic regulation network of SC fat tissue is necessary for the rational selection of Chinese domestic pig breeds. In the present study, SC adipocytes were isolated from Jiaxing Black pigs (a Chinese indigenous pig breed with redundant SC fat deposition) and Large White pigs (a lean-type pig breed with relatively low SC fat deposition) and the expression profiles of mRNAs and lncRNAs were compared by RNA-seq analysis to identify biomarkers correlated with the differences of SC fat deposition between the two breeds.Results: A total of 3,371 differentially expressed genes (DEGs) and 1,182 differentially expressed lncRNAs (DELs) were identified in SC adipocytes between Jiaxing Black (JX) and Large White (LW) pigs, which included 797 upregulated mRNAs, 2,574 downregulated mRNAs, 461 upregulated lncRNAs and 721 downregulated lncRNAs. Gene Ontology and KEGG pathway analyses revealed that the DEGs and DELs were mainly involved in the immune response, cell fate determination, PI3K-Akt signaling pathway and MAPK signaling pathway, which are known to be related to adipogenesis and lipid metabolism. The expression levels of DEGs and DELs according to the RNA-seq data were verified by quantitative PCR, which showed 81.8% consistency. The differences in MAPK pathway activity between JX and LW pigs was confirmed by western blot analysis, with <100-fold elevated p38 phosphorylation in JX pigs.Conclusions: This study offers a detailed characterization of mRNAs and lncRNAs in fat- and lean-type pig breeds. The activity of the MAPK signaling pathway was found to be associated with subcutaneous adipogenesis. These results greatly enhance our understanding of the molecular mechanisms regulating SC fat deposition in pigs.

Abstract
Background: This study aimed to evaluate the safety and efficacy of the intra-amniotic injection of ethacridine lactate in third trimester pregnancy patients and in patients with a history of cesarean section to induce labor.Methods : This retrospective clinical investigation analyzed 270 patients who underwent second or third trimester pregnancy termination at the affiliated hospital of Guangxi Guilin Medical University between January 1, 2017 and February 29, 2020, including those with and without cesarean section histories. Clinical characteristics and outcomes of all patients were analyzed following treatment with ethacridine lactate.Results: A total of 270 patients were hospitalized for pregnancy terminations, including 234 patients in a second trimester group, 36 patients in a third trimester group, 209 patients in a non-cesarean section group, and 61 patients in a cesarean section group. Among the 270 patients studied, five had twin pregnancies, and eight had two previous cesarean sections. All the included cases had successful vaginal delivery. There was no significant difference in prenatal and postpartum hemoglobin, incidence of massive hemorrhage, the rate of residual placenta and membranes, manual removal of placenta, uterine curettage,and blood transfusion between the second and third trimester groups (P > 0.05), as well as between the non-cesarean and cesarean section groups (P > 0.05). The abortion interval (AI) in the second trimester group was longer than that in the third trimester group (P = 0.014), and the hemorrhage of delivery in the third trimester group was significantly higher than in the second trimester group (P = 0.019). The hemorrhage of delivery in the cesarean section group was higher than that in the non-cesarean section group but displayed no significant difference (P > 0.05). No uterine rupture and placental abruption occurred in any of the patients.Conclusions : Intra-amniotic injection of ethacridine lactate demonstrated good clinical effects and could be used as a suitable method for third trimester pregnancy termination or pregnancy termination in women with prior cesarean sections, and it can also be used to induce labor in the second trimester for twin pregnancies and in patients with a history of two cesarean sections.
Drivers of unwanted births in Bangladesh (2004 ̶ 2014): A decomposition analysis
Authors: Rahman Md Mahfuzur , Tasnim Jannatul 
Published: April 2020

Abstract
Background

In Bangladesh, about 30 percent of the total births a woman on average have (2.3 births) are unwanted. Reduction in unwanted births is very important for family wellbeing, and control of rapid population growth. This reduction requires in-depth knowledge about the factors associated with the change in unwanted childbearing. This study examines the contributions of population structure, external factors that is family planning programmes, and their interaction to the change in the proportion of women having unwanted birth during 2004 ̶ 2007, 2007 ̶ 2011 and 2011 ̶ 2014.

Methods

This study uses the notion of standardization approach for measuring the effects of family planning programmes and non-programme factors on unwanted childbearing. Using Bangladesh Demographic and Health Survey data, we employ both aggregate and detailed three-fold decomposition technique to decompose the changes in the proportion having unwanted birth into the contributions of the three different factors. In decomposing the changes, we use logistic regression estimates.

Results

About 10.3 percent women are found to have unwanted birth in 2014. This percentage remains almost unchanged during 2004−2007, but declines significantly during 2007−2011 and 2011−2014. Population structure exerts significant reducing effect on proportion having unwanted birth during all the study periods, while external factors exerts significant negative effect only during 2011−2014. Interaction effect is found non-significant during all the study periods. All the factors found significantly associated with unwanted childbearing in logistic regression analysis do not show significant effect on its changes in detailed decomposition analysis. Structural effects of respondent’s age at marriage and education are found significantly negative during all the study periods.

Conclusions

In Bangladesh, significant reducing effect of population structure amid non-declining family planning programmes reduces the proportion having unwanted birth, while simultaneous reducing effects of structure and family planning programmes during a period result in a more pronounced decline. Substantial decline in women marrying before age 18 and having no education is likely to play a vital role in resulting a population structure that may have significant reducing effect on the proportion having unwanted birth.

Abstract
Background To evaluate the clinical characteristics and angiographic features of transcatheter angiographic embolization (TAE) in patients with active bleeding after percutaneous nephrolithotomy (PCNL).Methods Between October 2009 and April 2018, 45 patients who underwent TAE for hemorrhage control after PCNL were reviewed retrospectively. Patient clinical characteristics and angiographic features of TAE were analyzed.Results Of the 3148 patients, 45 (1.4%), including 35 men (77.78%) and 10 women (22.22%), were treated with TAE after PCNL. Ten patients (22.22%) had a history of kidney surgery. The interval from the bleeding episode to TAE was 3 days (range, 1–6 days). In addition, 27 (60.0%) and 18 patients (40.0%) experienced sudden onset of bleeding and delayed bleeding, respectively. Arterial laceration, arteriovenous fistula, and negative angiographic finding was found in 28 (62.2%), 7 (15.6%), and 10 patients (22.2%), respectively. Thirty-five patients (92.1%) achieved primary clinical success. The median corrected hemoglobin decrease from bleeding episode to TAE was 52 g/L (25.25, 71.00). The median corrected hemoglobin decrease rate from bleeding episode to TAE was 13.11 g/L d (5.60, 26.12). The hemoglobin decrease from bleeding episode to TAE was lesser in negative angiographic patients (28.50 (10.75,51.25) g/L VS 53.7 (35.0,73.13) g/L) than in positive angiographic patients (P<0.05).Conclusion TAE is a safe and effective treatment for patients with post-PCNL bleeding. TAE should be performed for post-PCNL bleeding in patients with hemoglobin decrease of >25 g/L or hemoglobin decrease rate of >5.5 g/L·d following conservative management.

Abstract
Background: Thoracic spinal stenosis (TSS) is a rare but intractable disease that fails to respond to conservative treatment. Thoracic spinal decompression, which is traditionally performed using high-speed drills and kerrison rongeurs, is a time-consuming and technically challenging task. Unfavorable outcomes and high incidence of complications are the major concerns. The development and adaptation of ultrasonic bone scalpel (UBS) has promoted its application in various spinal operations, but its application and standard operating procedure in thoracic decompression have not been fully clarified. Therefore, the purpose of this study is to describe our experience and technique note of using UBS, and come up with a standard surgical procedure for thoracic spinal decompression.Methods: A consecutive of 28 patients with TSS who underwent posterior thoracic spinal decompression surgery with UBS between December 2014 and May 2015 were enrolled in this study. Results: Thoracic spinal decompression surgery was successfully carried out in all cases via a single posterior approach. The mean operative time of single-segment laminectomy was 3.0±1.4min and the blood loss was 108.3±47.3ml. In circumferential decompression, the average blood loss was 513.8±217.0ml. Two cases of instrument-related nerve root injury occurred during operation and were cured by conservative treatment. Six patients have experienced cerebrospinal fluid (CSF) leakage postoperatively, but no related complications were observed. Conclusions: The UBS is an optimal instrument for thoracic spinal decompression, and its application enables surgeons to decompress the thoracic spinal cord safely and effectively. This standard operating procedure is expected to help achieve favorable outcomes, and can be used to treat various pathologies leading to thoracic spinal stenosis.
