Published: January 2021

Abstract
Background
Finding effective ways to support people aged > 50 years to develop adequate levels of physical activity and sedentary behavior is necessary as these behaviors are positively related to the maintenance of functional independence and health-related quality of life. Given the widespread provision of grandparental child care, examining its impact on grandparents’ energy-expenditure related behavior in the broader context of health is imperative. Therefore, the Healthy Grandparenting Project will aim to investigate the levels of physical activity and sedentary behavior, body composition and health-related quality of life in grandparents caring for their grandchildren and to compare these outcomes with non-caregiving grandparents and older adults without grandchildren, both momentarily and over time. An additional purpose is to identify possible predictors of potential changes over time.

Methods
A prospective cohort study will run over a period of 2 years, including three test occasions with a one-year time interval in between (T0 = baseline, T1 = 12 months, T2 = 24 months). A total of 276 participants will be recruited in Flanders through non-probability quota sampling (50–50% men-women), of which 92 caregiving grandparents, 92 non-caregiving grandparents and 92 non-grandparents. All three subsamples will be matched for age and sex. At each test occasion, anthropometric and body composition measurements will be determined. Participants’ levels of physical activity and sedentary behavior will be assessed both objectively and subjectively by means of accelerometry and self-report questionnaires. Information about their grandchildren and the provided grandparental care (if applicable) as well as their health-related quality of life will also be assessed using self-report questionnaires. Mixed modelling will be used to identify differences in physical activity, sedentary behavior, body composition and health-related quality of life between the subsamples at baseline, as well as to evaluate and compare changes in energy-expenditure related behavior over time between subsamples and to identify predictors of the detected changes.

Discussion
The Healthy Grandparenting Project is an innovative study examining the levels of physical activity and sedentary behavior in caregiving grandparents, non-caregiving grandparents and non-grandparents. Obtained results will help in the development of campaigns to maintain/improve health in adults at a more advanced age.

A study protocol for a randomised controlled trial to evaluate the effectiveness of a dog-facilitated physical activity minimal intervention on young children’s physical activity, health and development: the PLAYCE PAWS trial
Authors: Ng Michelle , Wenden Elizabeth , Lester Leanne , Westgarth Carri , Christian Hayley 
Published: January 2021

AbstractBackgroundPet ownership brings many health benefits to individuals. In children developmental benefits can extend to improved self-esteem, better social competence and decreased loneliness. The majority of households with children own a dog, however only a small proportion of children gain the benefits of dog ownership through dog walking and play. There are few intervention studies investigating the impact of dog-facilitated physical activity in children. The PLAYCE PAWS study aims to test a minimal-contact intervention through the use of mobile health (“mhealth”) strategies, i.e. text (SMS) messages, to parents to encourage their children to walk and play with their dog more, and evaluate the impact on children’s overall physical activity and development.Methods/designThe PLAYCE PAWS intervention study will target parents in dog-owning families with children aged 5 to 8 years in Perth, Western Australia. Approximately 150 dog-owning parents and children will be randomly allocated into either one of two intervention groups or a ‘usual care’ control group. The first intervention group will receive SMS messages over 4 weeks to encourage and prompt parents to undertake dog walking and dog play with their child. The second intervention group will receive the same text messages, plus a dog pedometer and personalised ‘dog steps’ diary for their child to complete. Parent-reported outcome measures include changes in children’s dog walking and play, overall physical activity, socio-emotional development, self-regulation, self-esteem, empathy, and level of attachment to their dog.DiscussionThe PLAYCE PAWS study appears to be the first to examine the effectiveness of a low-cost, mhealth intervention for increasing young children’s physical activity through dog walking and play. Given the high prevalence of dogs as family pets, this study presents a valuable opportunity to investigate if mHealth interventions encourage children to walk and play with their dog more, and if there are any associated impact on children’s overall physical activity and socio-emotional well-being. If effective, a larger trial or program could be implemented at low-cost and with wide reach in the community.Trial registrationANZCTR,ACTRN12620000288921.

Published: January 2021

Abstract
Background
Social capital has been linked to health behaviours, but the underlying mechanism is unclear. Previous studies have found that health literacy played the role of a mediator in the relationships among social capital, individual physical activity and nutrition. But it is not clear whether eHealth literacy mediates the impact of social capital on health behaviours. Therefore, our research aimed to explore the relationships among social capital (structural and cognitive social capital), eHealth literacy, and the health behaviours of elderly people, and to analyse the mediating effect of eHealth literacy, while providing a theoretical basis for a health behaviour intervention for elderly people.

Methods
From January to February 2019, we conducted a cross-sectional survey of 1201 Chinese people aged over 60 years using the Chinese Shortened Social Capital Scale (contains two subscales of structural social capital and cognitive social capital), eHealth Literacy Scale, and Health-Promoting Lifestyle Profile. We used structural equation modelling to test a hypothetical mediation model.

Results
The mean scores of social capital was 72.07 (SD = 13.03), 17.24 (SD = 9.34) for eHealth literacy, and 112.23 (SD = 23.25) for health behaviours. Social capital and eHealth literacy were significantly correlated with health behaviours, and social capital and structural social capital were significantly correlated with eHealth literacy. Lastly, eHealth literacy mediated the relationship between structural social capital and health behaviours.

Conclusions
eHealth literacy was an important mediating factor for elderly people’s structural social capital and health behaviours. Therefore, social capital and eHealth literacy must be considered when designing and implementing health behaviour intervention programmes for elderly people.

Abstract
Background
In China, achieving health equity has been regarded as a key issue for health reform and development in the current context. It is well known that unemployment has a negative effect on health. However, few studies have addressed the association between unemployment and inequity in health-related quality of life (HRQOL). This study aims to compare the inequality and inequity in HRQOL between the unemployed and employed in China.

Methods
The material regarding this study was derived from the Chinese National Health Services Survey of Shaanxi Province for 2013. We controlled for confounding factors by utilizing the coarsened exact matching method. Finally, 7524 employed individuals and 283 unemployed individuals who were 15 to 64 years old in urban areas were included in this study. We used HRQOL as the outcome variable, which was evaluated by using the Chinese version of EQ-5D-3L. The health concentration index, decomposition analysis based on the Tobit model, and the horizontal inequity index were employed to compute the socioeconomic-related equity between the unemployed and employed and the contribution of various factors.

Results
After matching, unemployed people tended to have poorer EQ-5D utility scores than employed people. There were statistically pro-rich inequalities in HRQOL among both employed and unemployed people, and the pro-rich health inequity of unemployed people was substantially higher than that of employed people. Economic status, age, education, smoking and health insurance were the factors influencing inequality in HRQOL between employed and unemployed individuals. Education status and basic health insurance have reduced the pro-rich inequity in HRQOL for unemployed people.

Conclusion
It is suggested that unemployment intensifies inequality and inequity in HRQOL. According to policymakers, basic health insurance is still a critical health policy for improving health equity for the unemployed. Intervention initiatives aiming to tackle long-term unemployment through active labour market programmes, narrow economic gaps, improve educational equity and promote the health status of the unemployed should be considered by the government to achieve health equity.

Published: January 2021

AbstractBackgroundThe COVID-19 outbreak is a global pandemic, during which the community preventive and protective behaviors play a crucial role in the containment and control of infection. This study was designed to contribute to the existing knowledge on how risk communication (RC) and risk perception (RP) affect protective and preventive behaviors (PPB) during the COVID-19 outbreak.MethodsThe required data were extracted from a national online survey of Iranian adults aged 15 and older during March 15–19, 2020 (n=3213). Data analysis was performed using structural equation modeling.ResultsThe study findings reveal that RC has direct and indirect positive effects on PB. Furthermore, this study also provides new evidence indicating that RP mediates the relationship between RC and PB and there is a two-way relationship between RC and RP. These interactions may have impact on risk communication strategies which should be adopted during this pandemic.ConclusionThe study findings have remarkable implications for informing future communications as well as interventions during this ongoing outbreak and subsequent national risk events.

Abstract
Background
Congenital bronchial atresia is a rare pulmonary abnormality characterized by the disrupted communication between the central and the peripheral bronchus and is typically asymptomatic. Although it can be symptomatic especially when infections occur in the involved areas, fungal infections are rare complications in patients with bronchial atresia. We report a case of congenital bronchial atresia complicated by a fungal infection.

Case presentation
A 30-year-old man with no previous history of immune dysfunction was brought to a nearby hospital and diagnosed with a left lung abscess. Although antimicrobial treatment was administered, it was ineffective, and he was transferred to our hospital. Since diagnostic imaging findings and bronchoscopy suggested congenital bronchial atresia and a fungal infection, he was treated with voriconazole and surgical resection was subsequently performed. A tissue culture detected Aspergillus fumigatus and histopathological findings were compatible with bronchial atresia. After discharge, he remained well and voriconazole was discontinued 5 months after the initiation of therapy.

Conclusion
Bronchial atresia is a rare disease that is seldom complicated by a fungal infection, which is also a rare complication; however, physicians should consider fungal infections in patients with bronchial atresia who present with infections resistant to antimicrobial treatment.
Incidence and clinical impact of vertebral endplate changes after limited lumbar microdiscectomy and implantation of a bone-anchored annular closure device
Authors: Kienzler Jenny C. , Rey Sofia , Wetzel Oliver , Atassi Hermien , Bäbler Sabrina , Burn Felice , Fandino Javier 
Published: January 2021

Abstract
Background
An annular closure device (ACD) could potentially prevent recurrent herniation by blocking larger annular defects after limited microdiscectomy (LMD). The purpose of this study was to analyze the incidence of endplate changes (EPC) and outcome after LMD with additional implantation of an ACD to prevent reherniation.

Methods
This analysis includes data from a) RCT study-arm of patients undergoing LMD with ACD implantation and b) additional patients undergoing ACD implantation at our institution. Clinical findings (VAS, ODI), radiological outcome (reherniation, implant integrity, volume of EPC) and risk factors for EPC were assessed.

Results
Seventy-two patients (37 men, 47 ± 11.63yo) underwent LMD and ACD implantation between 2013–2016. A total of 71 (99%) patients presented with some degree of EPC during the follow-up period (14.67 ± 4.77 months). In the multivariate regression analysis, localization of the anchor was the only significant predictor of EPC (p = 0.038). The largest EPC measured 4.2 cm3. Reherniation was documented in 17 (24%) patients (symptomatic: n = 10; asymptomatic: n = 7). Six (8.3%) patients with symptomatic reherniation underwent rediscectomy. Implant failure was documented in 19 (26.4%) patients including anchor head breakage (n = 1, 1.3%), dislocation of the whole device (n = 5, 6.9%), and mesh dislocation into the spinal canal (n = 13, 18%). Mesh subsidence within the EPC was documented in 15 (20.8%) patients. Seven (9.7%) patients underwent explantation of the entire, or parts of the device.

Conclusion
Clinical improvement after LMD and ACD implantation was proven in our study. High incidence and volume of EPC did not correlate with clinical outcome. The ACD might prevent disc reherniation despite implant failure rates. Mechanical friction of the polymer mesh with the endplate is most likely the cause of EPC after ACD.
A pacemaker-assisted microvascular decompression for a patient with left primary facial spasm and arrhythmia: a case report
Authors: Liu Yufei , Yang Jihu , Zhang Xiejun , Chen Fanfan , Zhang Liwei , Huang Guodong 
Published: January 2021

Abstract
Background
Primary facial spasm accompanied by arrhythmia is a rare clinical phenomenon and has not been reported before. We describe this phenomenon and discuss its mechanism and treatment.

Case presentation
We herein present a rare case of a patient with left primary facial spasm and a third-degree atrioventricular block (III degree AVB), who was implanted with a temporary cardiac pacemaker to receive microvascular decompression (MVD) because of refusal of a permanent cardiac pacemaker. The symptoms of facial spasm disappeared after MVD. The temporary cardiac pacemaker was removed on the second day after surgery. Her ECG still showed the third-degree atrioventricular block after a follow-up period of 5 months.

Conclusions
We are the first to report a patient with facial spasm and arrhythmia who was implanted with a temporary cardiac pacemaker to receive MVD. This case report demonstrated that the concomitant presence of a III degree AVB maybe not a contraindication for MVD, and the etiology of this facial spasm was the actual vascular compression of the facial nerve entry zone that was not related to the atrioventricular block.

Abstract
Background
Partial peri-cystectomy (PPC) is one of the major surgical approaches for hepatic cystic echinococcosis (CE) and has been practiced in most centers worldwide. Cysto-biliary communication (fistula, leakage, rupture) is a problematic issue in CE patients. T-tube is a useful technique in situations where an exploration and decompression are needed for common bile duct (CBD). However, postoperative biliary complications for cystic cavity still remains to be studied in depth.

Methods
A retrospective cohort analysis of CE cases in our single center database from 2007 March to 2012 December was performed. Patients (n = 51) were divided into two cohorts: double T-tube drainage (one at CBD for decompression and one at the fistula for sustaining in cystic cavity, n = 23) group and single T-tube drainage cohort (only one at CBD for decompression, n = 28). Short-/long-term postoperative complications focusing on biliary system was recorded in detail and they were followed-up for median 11 years.

Results
Overall biliary complication rates for double and single T-tube drainages were 17.4% vs. 39.3% (P > 0.05). Short-term complications ranged from minor to major leakages, cavity infection and abscess formation, and prevalence was 17.4% vs. 21.4% (P > 0.05) respectively for double and single T-tube groups; most importantly, double T-tube drainage group had obvious advantages regarding long-term complications (P < 0.05), which was biliary stricture needing surgery and it was observed only in single T-tube drainage group.

Conclusions
Double T-tube drainage had better outcomes without procedure-specific postoperative biliary complications than single T-tube drainage. Meanwhile, we recommend long-term follow-up when comparing residual cavity related biliary complications in CE patients as it could happen lately.

Published: January 2021

Abstract
Background
Esophageal leiomyosarcoma (LMS) is a rare tumor that constitutes less than 1% of all malignant esophageal tumors. Concurrent occurrence of esophageal leiomyosarcoma with squamous cell carcinoma (SCC) is even rarer than isolated leiomyosarcoma.

Case presentation
In this report, we present a case of concurrent leiomyosarcoma and SCC in a 64-year-old woman presenting with vomiting and solid dysphagia, which has not been properly diagnosed following several referrals and diagnostic modalities. At last Exploratory laparotomy with gastric pull-up was performed in addition to radical laryngectomy with partial resection of the esophagus and subtotal thyroidectomy. Pathologic evaluation of the surgical specimen showed concurrent LMS (5.2 × 4.5 × 3 cm) and SCC (1.5 × 0.6 × 0.6 cm) at the same anatomical level in the proximal esophagus.

Conclusions
This study proposes the importance of using ancillary diagnostic tests such as immunohistochemistry (IHC) to diagnose less common cases such as concurrent LMS and SCC.

Published: January 2021

Abstract
Background
A horseshoe kidney is a congenital malformation involving the fusion of the bilateral kidneys and is often accompanied by anomalies of the ureteropelvic and vascular systems. When performing resection of colorectal cancer in a patient with horseshoe kidney, damage to the ureter or excessive renal arteries should be avoided. To achieve this purpose, comprehensive preoperative anatomical assessments and surgical planning are important. Here, we report a case of a laparoscopic abdominal perineal rectal resection for lower rectal cancer with a horseshoe kidney.

Case presentation
A 79-year-old woman presented with bloody stool and was diagnosed with advanced lower rectal cancer, immediately above the rectal dentate line, without metastasis. A preoperative computed tomography (CT) scan revealed a horseshoe kidney, while a three-dimensional CT (3D-CT) angiography revealed aberrant excess renal artery from the aorta to the renal isthmus. The left ureter ran in front of the isthmus of the horseshoe kidney and presented calculus formation. Laparoscopic abdominal perineal rectal resection was performed with D3 lymph node dissection. During the operation, we mobilized the sigmoid colon mesentery via a medial approach and preserved the left ureter, the left gonadal vessels, and the hypogastric nerve plexus in the retroperitoneum in front of the horseshoe kidney.

Conclusions
We report a rare case of rectal cancer surgery in a patient with a horseshoe kidney. We discuss the anatomical peculiarities of a horseshoe kidney, such as excess renal arteries, inferior vena cava, ureter, gonadal vessels, and nerves, that should be preserved according to the literature. We suggest that preoperative 3D-CT angiography is both useful for revealing the relationship between the vascular system and a horseshoe kidney and helpful when performing laparoscopic surgery for a left-sided colon and rectal cancer to avoid intraoperative injury.
