Published: July 2021

Abstract
Background
The onset of mental health problems generally occurs between the ages of 16 and 23 – the years in which young people follow post-secondary education, which is a major channel in our society to prepare for a career and enhance life goals. Several studies have shown that students with mental health problems have a higher chance of early school leaving. Supported Education services have been developed to support students with mental health problems to remain at school. The current project aims to study the effect of an individually tailored Supported Education intervention on remaining at school, study success, and satisfaction of students with mental health problems studying at an institute for intermediate vocational education and a university of applied sciences in the Netherlands.

Methods/design
The design combines quantitative research (Randomized Controlled Trial; RCT) with qualitative research (monitoring, interviews, focus groups). One hundred students with mental health problems recruited from the two educational institutes will be randomly allocated to either the intervention or control condition. The students in the intervention condition receive the Supported Education intervention given by a Supported Education specialist, the students in the active control condition receive support as usual plus advice from a trained staff member on potential supportive resources regarding studying with mental health problems. The primary outcome ‘remaining at school’, and the secondary outcome ‘study success’ will be determined using data from the school’s administration. The secondary outcome ‘student satisfaction’ and other variables that will be studied in a more exploratory way, such as self-efficacy and study skills, will be determined through online questionnaires at baseline, at 6 and at 12 months follow-up. Focus groups and interviews with the students and Supported Education specialists will be carried out to complement the trial.

Discussion
This RCT is the first to assess the effect of Supported Education on remaining at school, next to study success and student satisfaction among students with mental health problems. The use of a mixed-methods design will result in a thorough evaluation of the effect of the intervention. Issues regarding the influx and possible attrition of students in the follow-up are discussed.

Adolescent psychopathology and psychological wellbeing: a network analysis approach
Authors: Campbell Stephanie , Osborn Tom L. 
Published: July 2021

Abstract
Background
The extent to which psychological wellbeing may play a preventive and therapeutic role in the development and maintenance of adolescent emotional disorders depends, in part, on the nature of the overlap between these two constructs. We estimated network analysis to examine the relationship between adolescent psychopathology (measured by depression and anxiety symptoms) and psychological wellbeing (measured by happiness, optimism, social support, perceived control, and gratitude).

Methods
This was a cross-sectional study with a large community sample of Kenyan adolescents (N = 2192, aged 13–18). Network analyses were conducted to examine the topology, stability, centrality, and bridge nodes of a network of psychopathology and psychological wellbeing measures.

Results
Two distinct community clusters emerged, one for psychopathology nodes and another for wellbeing nodes, suggesting that these are two distinct but connected concepts. Central and bridge nodes of the wellbeing and psychopathology network were identified. The most central nodes in the network were family provides emotional help and support and self-blame; the strongest negative edges between psychopathology and psychological wellbeing were depressed mood—I love life and irritability—I am a joyful person; the main bridge nodes were family helps me and I can talk to family about problems.

Conclusions
Our findings expand understanding of the relationship between psychopathology and wellbeing in an understudied population and are suggestive of how psychological wellbeing can inform psychopathological treatment and preventive efforts in low-income regions such as those in Sub Saharan Africa.

Abstract
Background
The suicide rate in Canada decreased by 24% during the past four decades. However, rates vary between provinces and territories, and not all jurisdictions experienced the same changes. This study examined suicide rates over time in the province of Newfoundland and Labrador.

Methods
We used cross-sectional surveillance data from the Canadian Vital Statistics Death Database to examine suicide rates in Newfoundland and Labrador from 1981 to 2018. We calculated annual age-standardized suicide mortality rates and used joinpoint regression to estimate the average annual percent change (AAPC) in suicide rates overall and by sex, age group, and means of suicide.

Results
From 1981 to 2018, 1759 deaths by suicide were recorded among people in Newfoundland and Labrador. The age-standardized suicide mortality rate increased more than threefold over the study period, from 4.6 to 15.4 deaths per 100,000. The suicide rate was higher among males than females, and accounted for 83.1% of suicide deaths (n = 1462); the male-to-female ratio of suicide deaths was 4.9 to 1. The average annual percent change in suicide rates was higher among females than males (6.3% versus 2.0%). Age-specific suicide rates increased significantly for all age groups, except seniors (aged 65 or older); the largest increase was among youth aged 10 to 24 years old (AAPC 3.5; 95% CI, 1.6 to 5.5). The predominant means of suicide was hanging/strangulation/suffocation, which accounted for 43.8% of all deaths by suicide.

Conclusions
The suicide rate in Newfoundland and Labrador increased steadily between 1981 and 2018, which was in contrast to the national rate decline. The disparity between the provincial and national suicide rates and the variations by sex and age underscore the need for a public health approach to prevention that accounts for geographic and demographic differences in the epidemiology of suicide.

Abstract
Study design
This is a prospective case-controlled study.

Background
To analyze the postoperative axial pain and cage subsidence of patients presenting with cervical spondylotic myelopathy (CSM) after a modified procedure of ACDF (mACDF).

Methods
Ninety patients with CSM were prospectively collected from 2014 to 2018. The patients were divided into spread group and non-spread group (48:42 ratio) according to the cage placement with or without releasing the Caspar cervical retractor after decompression. Spread group received conventional ACDF and non-spread group received mACDF. Patients were followed-up for at least 24 months after surgery. Radiologic data, including height of intervertebral space and Cobb Angle, were collected. Nervous system function was obtained using JOA scores, and level of pain was assessed using VAS scores.

Results
A total of 90 patients were enrolled and the patients were divided into spread group (n = 48) and none-spread group(n = 42). Cage subsidence of (spread group vs none-spread group) was (0.82 ± 0.68 vs 0.58 ± 0.81) mm, (0.64 ± 0.77 vs 0.34 ± 0.46) mm, (0.48 ± 0.43 vs 0.25 ± 0.28) mm, and (0.45 ± 0.47 vs 0.17 ± 0.32) mm at 3 months, 6 months, 12 months and 24 months, respectively. The period exhibiting the most decrease of the height of intervertebral space was 3 months postoperatively. However, there was no statistical difference in the height of intervertebral space, JOA or VAS scores at the final follow-up between the two groups.

Conclusions
The mACDF can avoid excessive distraction by releasing the Caspar Cervical retractor, restore the “natural height” of cervical vertebra, relieve immediate pain after surgery, and prevent rapid Cage subsidence and the loss of cervical curvature.
Madelung’s disease in a non-alcoholic Ethiopian male patient mistaken for obesity: a case report
Authors: Zewde Yared Zenebe 
Published: July 2021

Abstract
Background
Madelung’s disease (MD) is a rare disorder of fat storage characterized by the presence of diffuse, symmetrical deposition of subcutaneous fat around the neck, shoulder, arm, trunk and thigh. Although its cause is not fully understood, this benign condition is commonly presented among adult males with Mediterranean origin and history of alcohol abuse. Patients often presents with compression of vital structures, cosmetic disfigurement and associated psychosocial problems and systemic comorbidities. It is often under-recognized by physicians, possibly due to obliviousness of the condition and often misdiagnosed as obesity.

Case presentation
We present a 65-year-old non-alcoholic black Ethiopian man, presented with a slowly growing body fat in his trunk and proximal limbs associated by multiple joint and back pain which got worse recently. He denied any history of chronic alcohol use. On examination, huge, bilateral, non-tender, soft, globular masses in his torso, shoulder, arm and thigh with bilateral breast enlargement. On investigation his biochemical profile was normal except hyperuricemia (10.6 mg/dl). Imaging of the cervical and lumbar vertebrae showed excess subcutaneous fat depositions with degenerative disc disease. Biopsy from the mass revealed non-encapsulated lipoma and he was diagnosed with type II MD. We treated his pain with supportive therapy and discharged in stable condition. The patient deferred surgical treatment.

Conclusions
Madelung’s disease is often reported among white adult males with chronic alcoholism. However, our case reported a black man without the typical risk factor which was misdiagnosed as obesity. Hence, clinicians should be aware of MD and need to consider it in their differential diagnosis when encountered with a patient having progressive centripetal fat deposition with or without a history of alcoholism and systemic comorbidities. As early detection of this disorder helps to avoid diagnostic delays and prevent complications through timely interventions which will in turn improves patient quality of life.

Published: July 2021

Abstract
Background
Parasite persistence, exacerbated and sustained immune response, and continuous oxidative stress have been described to contribute to the development of the cardiac manifestations in Chronic Chagas Disease. Nevertheless, there are no efficient therapies to resolve the Trypanosoma cruzi infection and prevent the disease progression. Interestingly, trypanocide, antioxidant, and immunodulatory properties have been reported separately for some major terpenes, as citral (neral plus geranial), limonene, and caryophyllene oxide, presents in essential oils (EO) extracted from two chemotypes (Citral and Carvone) of Lippia alba. The aim of this study was to obtain L. alba essential oil fractions enriched with the aforementioned bioactive terpenes and to evaluate the impact of these therapies on trypanocide, oxidative stress, mitochondrial bioenergetics, genotoxicity, and inflammatory markers on T. cruzi-infected macrophages.

Methods
T. cruzi-infected J774A.1 macrophage were treated with limonene-enriched (ACT1) and citral/caryophyllene oxide-enriched (ACT2) essential oils fractions derived from Carvone and Citral-L. alba chemotypes, respectively.

Results
ACT1 (IC50 = 45 ± 1.7 μg/mL) and ACT2 (IC50 = 80 ± 1.9 μg/mL) exhibit similar trypanocidal effects to Benznidazole (BZN) (IC50 = 48 ± 2.5 μg/mL), against amastigotes. Synergistic antiparasitic activity was observed when ACT1 was combined with BZN (∑FIC = 0.52 ± 0.13 μg/mL) or ACT2 (∑FIC = 0.46 ± 1.7 μg/mL). ACT1 also decreased the oxidative stress, mitochondrial metabolism, and genotoxicity of the therapies. The ACT1 + ACT2 and ACT1 + BZN experimental treatments reduced the pro-inflammatory cytokines (IFN-γ, IL-2, and TNF-α) and increased the anti-inflammatory cytokines (IL-4 and IL-10).

Conclusion
Due to its highly trypanocidal and immunomodulatory properties, ACT1 (whether alone or in combination with BZN or ACT2) represents a promising L. alba essential oil fraction for further studies in drug development towards the Chagas disease control.

Abstract
Background
Radioresistance can pose a significant obstacle to the effective treatment of breast cancers. Epithelial–mesenchymal transition (EMT) is a critical step in the acquisition of stem cell traits and radioresistance. Here, we investigated whether Maprang seed extract (MPSE), a gallotannin-rich extract of seed from Bouea macrophylla Griffith, could inhibit the radiation-induced EMT process and enhance the radiosensitivity of breast cancer cells.

Methods
Breast cancer cells were pre-treated with MPSE before irradiation (IR), the radiosensitizing activity of MPSE was assessed using the colony formation assay. Radiation-induced EMT and stemness phenotype were identified using breast cancer stem cells (CSCs) marker (CD24−/low/CD44+) and mammosphere formation assay. Cell motility was determined via the wound healing assay and transwell migration. Radiation-induced cell death was assessed via the apoptosis assay and SA-β-galactosidase staining for cellular senescence. CSCs- and EMT-related genes were confirmed by real-time PCR (qPCR) and Western blotting.

Results
Pre-treated with MPSE before irradiation could reduce the clonogenic activity and enhance radiosensitivity of breast cancer cell lines with sensitization enhancement ratios (SERs) of 2.33 and 1.35 for MCF7 and MDA-MB231cells, respectively. Pretreatment of breast cancer cells followed by IR resulted in an increased level of DNA damage maker (γ-H2A histone family member) and enhanced radiation-induced cell death. Irradiation induced EMT process, which displayed a significant EMT phenotype with a down-regulated epithelial marker E-cadherin and up-regulated mesenchymal marker vimentin in comparison with untreated breast cancer cells. Notably, we observed that pretreatment with MPSE attenuated the radiation-induced EMT process and decrease some stemness-like properties characterized by mammosphere formation and the CSC marker. Furthermore, pretreatment with MPSE attenuated the radiation-induced activation of the pro-survival pathway by decrease the expression of phosphorylation of ERK and AKT and sensitized breast cancer cells to radiation.

Conclusion
MPSE enhanced the radiosensitivity of breast cancer cells by enhancing IR-induced DNA damage and cell death, and attenuating the IR-induced EMT process and stemness phenotype via targeting survival pathways PI3K/AKT and MAPK in irradiated breast cancer cells. Our findings describe a novel strategy for increasing the efficacy of radiotherapy for breast cancer patients using a safer and low-cost natural product, MPSE.
Trends in Swedish physicians’ attitudes towards physician-assisted suicide: a cross-sectional study
Authors: Lynøe Niels , Lindblad Anna , Engström Ingemar , Sandlund Mikael , Juth Niklas 
Published: July 2021

Abstract
Aims
To examine attitudes towards physician-assisted suicide (PAS) among physicians in Sweden and compare these with the results from a similar cross-sectional study performed in 2007.

Participants
A random selection of 250 physicians from each of six specialties (general practice, geriatrics, internal medicine, oncology, surgery and psychiatry) and all 127 palliative care physicians in Sweden were invited to participate in this study.

Setting
A postal questionnaire commissioned by the Swedish Medical Society in collaboration with Karolinska Institute in Stockholm.

Results
The total response rate was 59.2%. Slightly fewer than half [47.1% (95% CI 43.7–50.5)] of the respondents from the six specialties accepted PAS, which is significantly more than accepted PAS in the 2007 study [34.9% (95% CI 31.5–38.3)]. Thirty-three percent of respondents were prepared to prescribe the needed drugs. When asked what would happen to the respondent’s own trust in healthcare, a majority [67.1% (95% CI 63.9–70.3)] stated that legalizing PAS would either not influence their own trust in healthcare, or that their trust would increase. This number is an increase compared to the 2007 survey, when just over half [51.9% (95% CI 48.0–55.2)] indicated that their own trust would either not be influenced, or would increase.

Conclusions
The study reveals a shift towards a more accepting attitude concerning PAS among physicians in Sweden. Only a minority of the respondents stated that they were against PAS, and a considerable proportion reported being prepared to prescribe the needed drugs for patient self-administration if PAS were legalized.
Perspective of potential patients on the hospital volume-outcome relationship and the minimum volume threshold for total knee arthroplasty: a qualitative focus group and interview study

Published: July 2021

Abstract
Background
Total knee arthroplasty (TKA) is performed to treat end-stage knee osteoarthritis. In Germany, a minimum volume threshold of 50 TKAs/hospital/year was implemented to ensure outcome quality. This study, embedded within a systematic review, aimed to investigate the perspectives of potential TKA patients on the hospital volume-outcome relationship for TKA (higher volumes associated with better outcomes).

Methods
A convenience sample of adults with knee problems and heterogeneous demographic characteristics participated in the study. Qualitative data were collected during a focus group prior to the systematic review (n = 5) and during telephone interviews, in which preliminary results of the systematic review were discussed (n = 16). The data were synthesised using content analysis.

Results
All participants (n = 21) believed that a hospital volume-outcome relationship exists for TKA while recognising that patient behaviour or the surgeon could also influence outcomes. All participants would be willing to travel longer for better outcomes. Most interviewees would choose a hospital for TKA depending on reputation, recommendations, and service quality. However, some would also choose a hospital based on the results of the systematic review that showed slightly lower mortality/revision rates at higher-volume hospitals. Half of the interviewees supported raising the minimum volume threshold even if this were to increase travel time to receive TKA.

Conclusions
Potential patients believe that a hospital volume-outcome relationship exists for TKA. Hospital preference is based mainly on subjective factors, although some potential patients would consider scientific evidence when making their choice. Policy makers and physicians should consider the patient perspectives when deciding on minimum volume thresholds or recommending hospitals for TKA, respectively.
Who are the beneficiaries and what are the reasons for non-utilization of care respite and support services? A cross-sectional study on family caregivers
Authors: Huang Jianan , Münzel Nadja , Scheel-Sailer Anke , Gemperli Armin 
Published: July 2021

Abstract
Background
Family caregivers assume substantial caregiving responsibilities for persons with chronic conditions, such as individuals with spinal cord injury, which leads to negative impacts on their lives. Respite care and other services are provided as a temporary relief and support for them. Design of appropriate respite care programs depends on identification of beneficiary subgroups for the different types of service. This study aimed to quantify the uptake of different respite and support services for family caregivers, the reasons for non-use, and to explore the respective predictors.

Methods
A cross-sectional survey of family caregivers of persons with spinal cord injury was conducted nationwide in Switzerland. The use of 11 different respite and support services during the previous 12 months was investigated, along with caregivers’ reasons for not using any respite. Classification trees were used to characterize the beneficiaries and reasons for not using respite.

Results
About a third of family caregivers used at least one type of respite or support service during the previous 12 months. Utilization of respite care was greater among those who employed professional home care (57% vs 24% of those without professional home care). Marked cantonal differences were also observed in utilization of respite care. The primary reason for not using respite services was “no demand” (80% of non-users of respite services), mainly among caregivers who were less emotionally affected by their caregiving tasks.

Conclusions
Utilization of respite and support services depends more on place of residence and use of home care services than on functional status of the care recipient. Accordingly, programs should be tailored to the cultural context of their potential users. This is best achieved through coordination with local health care professionals who can identify needs, provide information, initiate referrals, and integrate the care into a larger support plan.
