Published: May 2020

Cancer is a major cause of increased morbidity and mortality in today’s world. Several studies have shown that its incidence is governed by the gender and age of a person. The site and histological subtype of cancer vary between different age groups and sex. Knowledge of the demography of cancer in affected individuals will help in planning screening and prevention strategies. The present study was done to analyse the site of different cancers among various age groups and gender in patients coming to a tertiary care centre. Data of cancer patients was retrospectively analysed in terms of age, sex, site, and histopathological subtypes. The histopathological reports of all cases of cancer recorded at the histopathology laboratory of the tertiary care centre during a one year period- November 2017 to October 2018 were perused and the findings were recorded. Analysis of the data was done using SPSS version 17 to obtain the statistical significance. There were a total of 330 cases of cancer recorded during the study period. Out of these, 143 were male and 187 were female. Age group between 51 and 60 years had the maximum number of cases of cancer. Breast cancer in female and stomach cancer and oropharyngeal cancer in male were found to be more common. Among the histological subtypes, adenocarcinoma was found to be the most commonest across all ages and in both sexes.

Published: May 2020

This investigation determined differences in
lower body strength and power between elite junior (17-20 years) and elite
senior (open-aged) rugby league athletes. Twenty junior and 25 senior athletes
performed an isometric mid-thigh pull, countermovement jump, repeated jump, and
broad jump tests during a National Rugby League pre-season. The effects of age
(junior vs. senior) and position (adjustables vs. hit-up forwards vs. outside
backs) on test results were investigated using a two-way analysis of variance.
Cohen’s d effect sizes (ES) and 95% confidence intervals were calculated for
pairwise comparisons. Isometric mid-thigh pull absolute peak force was greater
for senior players compared to junior players (ES=0.88, p<.05).
Countermovement jump absolute peak power was greater for outside backs
(ES=1.12) and hit-up forwards (ES=1.23) compared to adjustables (p<.05),
greater for senior outside backs compared to junior outside backs (ES=1.53, p<.05),
and greater for junior hit-up forwards compared to senior hit-up forwards
(ES=1.00, p<.05). This research demonstrated the differences in strength and
power of rugby league athletes between playing age and position. Improving
lower body strength should be prioritised for athletic development of junior
rugby league athletes, with consideration given to requirements across
different playing positions.

Authors: Febrianti Asterina , Khotimah Annisa Nurul
Published: May 2020

It was noted that from 2011 to 2017 rice production in Indonesia had increased by 23.77%. Perusahaan X is a rice supplier company in Bandung city with the transfer of rice carried out by porters (kuli panggul) manually without tools. Porters do the lifting process with a duration of 9 hours and the load carried weights from 10 kg to 50 kg. Repetitive and monotonous task can increase stress levels and fatigue at work. Improvement  of work condition is needed through the measurement of stress and fatigue level on the porters of rice in Perusahaan X using cocorometer and The Subjective Self Rating Test (SSRT) questionnaire to increase productivity in the company. Ten men as respondent with ages ranging from 20-41 years with work experience of 1-6 years were tested. The result shows that respondents before work (α/2table< α/2calculated< α/2tableor 0.025 < 0.544 < 0.975) and after work (α/2table< α/2calculated< α/2tableor 0.025 < 0.413 < 0.975) experienced increased stress and fatigue level. The correlation between stress and fatigue level before work (degree of freedom = -0.219) and after work (degree of freedom = -0.292) shows low correlation. Stress level is not only influenced by fatigue level but also influenced by the age and work experience of respondents during work. Perusaahaan X should do several things to reduce the increased in stress and fatigue by creating a pleasant atmosphere at work; requiring the workers to do stretching at rest break; providing  bonus; and providing drinking water so that respondents are not dehydrated. Keywords: Stress, fatigue, cocorometer, SSRT

Authors: Fleming Theresa , Merry S , Stasiak K , Hopkins S , Patolo T , Ruru S , Latu M , Shepherd M , Christie G , Goodyear-Smith F
Published: May 2020

© 2019 Journal of Medical Internet Research. All rights reserved. Background: New Zealand youth, especially those of Maori and Pacific descent, have high rates of depression, anxiety, and self-harm, but have low rates of help-seeking from mental health professionals. Apps, computerized therapy, and other digital tools can be effective, highly scalable treatments for anxiety and depression. Co-design processes are often used to foster engagement with end users, but this does not always lead to high levels of engagement. Objective: We aimed to carry out preliminary scoping to understand adolescents' current internet use and diversity of preferences to inform a planned co-design process for creating digital mental health tools for teenagers. Methods: Interactive workshops and focus groups were held with young people. Data were analyzed using a general inductive approach. Results: Participants (N=58) engaged in 2 whanau (extended family) focus groups (n=4 and n=5), 2 school- or community-based focus groups (n=9 each), and 2 workshops (n=11 and n=20). The authors identified 3 overarching themes: (1) Digital mental health tools are unlikely to be successful if they rely solely on youth help-seeking. (2) A single approach is unlikely to appeal to all. Participants had diverse, noncompatible preferences in terms of look or feel of an app or digital tool. The authors identified 4 user groups players or gamers, engagers, sceptics, and straight-talkers. These groups differed by age and degree of current mental health need and preferred gamified or fun approaches, were open to a range of approaches, were generally disinterested, or preferred direct-to-the-point, serious approaches, respectively. (3) Digital mental health tools should provide an immediate response to a range of different issues and challenges that a young person may face. Conclusions: Defining the preferences of different groups of users may be important for increasing engagement with digital therapies even within specific population and mental health-need groups. This study demonstrates the importance of scoping possible user needs to inform design processes.

© Theresa Fleming, Lynda Bavin, Mathijs Lucassen, Karolina Stasiak, Sarah Hopkins, Sally Merry. Background: Digital self-help interventions (including online or computerized programs and apps) for common mental health issues have been shown to be appealing, engaging, and efficacious in randomized controlled trials. They show potential for improving access to therapy and improving population mental health. However, their use in the real world, ie, as implemented (disseminated) outside of research settings, may differ from that reported in trials, and implementation data are seldom reported. Objective: This study aimed to review peer-reviewed articles reporting user uptake and/or ongoing use, retention, or completion data (hereafter usage data or, for brevity, engagement) from implemented pure self-help (unguided) digital interventions for depression, anxiety, or the enhancement of mood. Methods: We conducted a systematic search of the Scopus, Embase, MEDLINE, and PsychINFO databases for studies reporting user uptake and/or usage data from implemented digital self-help interventions for the treatment or prevention of depression or anxiety, or the enhancement of mood, from 2002 to 2017. Additionally, we screened the reference lists of included articles, citations of these articles, and the titles of articles published in Internet Interventions, Journal of Medical Internet Research (JMIR), and JMIR Mental Health since their inception. We extracted data indicating the number of registrations or downloads and usage of interventions. Results: After the removal of duplicates, 970 papers were identified, of which 10 met the inclusion criteria. Hand searching identified 1 additional article. The included articles reported on 7 publicly available interventions. There was little consistency in the measures reported. The number of registrants or downloads ranged widely, from 8 to over 40,000 per month. From 21% to 88% of users engaged in at least minimal use (eg, used the intervention at least once or completed one module or assessment), whereas 7-42% engaged in moderate use (completing between 40% and 60% of modular fixed-length programs or continuing to use apps after 4 weeks). Indications of completion or sustained use (completion of all modules or the last assessment or continuing to use apps after six weeks or more) varied from 0.5% to 28.6%. Conclusions: Available data suggest that uptake and engagement vary widely among the handful of implemented digital self-help apps and programs that have reported this, and that usage may vary from that reported in trials. Implementation data should be routinely gathered and reported to facilitate improved uptake and engagement, arguably among the major challenges in digital health.

Published: May 2020

Background: Depression often emerges for the first time during adolescence. There is accumulating evidence that universal depression prevention programs may have the capacity to reduce the impact of depression when delivered in the school environment. Objective: This trial investigated the effectiveness of SPARX-R, a gamified online cognitive behavior therapy intervention for the prevention of depression relative to an attention-matched control intervention delivered to students prior to facing a significant stressor-final secondary school exams. It was hypothesized that delivering a prevention intervention in advance of a stressor would reduce depressive symptoms relative to the control group. Methods: A cluster randomized controlled trial was conducted in 10 government schools in Sydney, Australia. Participants were 540 final year secondary students (mean 16.7 [SD 0.51] years), and clusters at the school level were randomly allocated to SPARX-R or the control intervention. Interventions were delivered weekly in 7 modules, each taking approximately 20 to 30 minutes to complete. The primary outcome was symptoms of depression as measured by the Major Depression Inventory. Intention-to-treat analyses were performed. Results: Compared to controls, participants in the SPARX-R condition (n=242) showed significantly reduced depression symptoms relative to the control (n=298) at post-intervention (Cohen d=0.29) and 6 months post-baseline (d=0.21) but not at 18 months post-baseline (d=0.33). Conclusions: This is the first trial to demonstrate a preventive effect on depressive symptoms prior to a significant and universal stressor in adolescents. It demonstrates that an online intervention delivered in advance of a stressful experience can reduce the impact of such an event on the potential development or exacerbation of depression.
Serious games for mental health: Are they accessible, feasible, and effective? A systematic review and meta-analysis
Authors: Lau HM , Smit JH , Fleming Theresa , Riper H
Published: May 2020

© 2017 Lau, Smit, Fleming and Riper. Introduction: The development and use of serious games for mental health disorders are on the rise. Yet, little is known about the impact of these games on clinical mental health symptoms. We conducted a systematic review and meta-analysis of randomized controlled trials that evaluated the effectiveness of serious games on symptoms of mental disorder. Method: We conducted a systematic search in the PubMed, PsycINFO, and Embase databases, using mental health and serious games-related keywords. Ten studies met the inclusion criteria and were included in the review, and nine studies were included in the meta-analysis. Results: All of the serious games were provided via personal computer, mostly on CD-ROM without the need for an internet connection. The studies targeted age groups ranging from 7 to 80 years old. The serious games focused on symptoms of depression (n = 2), post-traumatic stress disorder (n = 2), autism spectrum disorder (n = 2), attention deficit hyperactivity disorder (n = 1), cognitive functioning (n = 2), and alcohol use disorder (n = 1). The studies used goal-oriented (n = 4) and cognitive training games (n = 6). A total of 674 participants were included in the meta-analysis (380 in experimental and 294 in control groups). A meta-analysis of 9 studies comprising 10 comparisons, using a random effects model, showed a moderate effect on improvement of symptoms [g = 0.55 (95% confidence interval 0.28-0.83); P < 0.001], favoring serious games over no intervention controls. Discussion/conclusion: Though the number of comparisons in the meta-analysis was small, these findings suggest that serious gaming interventions may be effective for reducing disorder-related symptoms. More studies are needed in order to attain deeper knowledge of the efficacy for specific mental disorders and the longer term effects of this new type of treatment for mental disorders.

Results: The mean age of the participants was 32.5 ± 9.5 years with male predominance of 462 (94.3%) while 375 (76.5%) were first time donors. Of the 490 HBsAg negative blood donors, 89 (18.2%) were positive for anti-HBc. The highest prevalence of anti-HBc occurred in the 26-34 years age group. Independent risk factors associated with the presence of anti-HBc included age (p = 0.049), marital status (p = 0.003), dental and surgical procedure (p<0.001), traditional practices such as tattoo, body piercing and scarification (p<0.001) and previous blood transfusion (p = 0.016). Conclusion: Age, marital status, traditional and cultural practices like scarifications, tattoo and body piercing and history of blood transfusion were risk factors associated with HBV infection despite HBsAg negativity.

Published: May 2020

Background: Pneumonia in children is a leading cause of morbidity and mortality in developing countries. It is often complicated by Congestive Cardiac Failure (CCF), with some of the symptoms similar to those of pneumonia. Brain Natriuretic Peptide (BNP) assay can differentiate cardiac from respiratory-related causes of respiratory distress. Objective: To determine the role of BNP in differentiating isolated pneumonia from pneumonia complicated by CCF. Methods: Over a 12-month period, consecutive children with radiologically-confirmed pneumonia were recruited for the study. Those with complicating CCF were noted. All the children had blood BNP assay done by ELISA, prior to treatment. Biodata was obtained and the children were grouped into those with isolated pneumonia and those with pneumonia complicated by CCF. Results: Fifty children were recruited; of these 26 (52.0%) had isolated pneumonia while 24 (48.0%) had pneumonia with CCF. The median age of the children was 6 months. The median BNP values for the isolated pneumonia group (229.4 ng/l), was significantly lower than that of pneumonia complicated by CCF group (917.3 ng/l); (p = 0.007). ROC showed that a BNP value >550ng/l could identify children with pneumonia complicated with CCF from those with isolated pneumonia with a sensitivity of 70.4% and specificity of 63.4%. Conclusion: A BNP assay prior to treatment of >550ng/l can differentiate children with pneumonia complicated with CCF from those without CCF.

Background: Nigeria reportedly has one of the highest incidences of congenital hearing loss and the Universal Neonatal Hearing Screening (UNHS) offers a potential for early detection and intervention. Objectives: To determine the awareness and acceptability of newborn hearing screening among the antenatal clinic attendees of a Nigerian Teaching Hospital. Methods: This study was a cross-sectional survey among the pregnant women attending the antenatal clinic. Data were obtained using semi-structured interviewer-administered questionnaire Results: A total of 114 women aged 18 and 45 years participated in the survey; 51/114 (44.7%) were aware of hearing screening with most of them 39/51 (76.5%) having health workers as their first source of knowledge. A high acceptance rate was obtained among 97/114 (85.1%), and this was notably independent (p = 0.399) of awareness; 14/114 (12.2%) rejected UNHS and the commonest reason for rejection was lack of enough information among 10/14 (71.4%) on the existence and use of UNHS. Health care workers were the commonest source of information [39/51(76.5%)]. A majority [51/58 (87.9%)] thought that the best time to initiate treatment is early in life, before speech development, only 4/114 (3.5%) had relatives who had ever undergone UNHS and all were done abroad. Conclusions: Less than half of the participants attending ANC were aware of hearing screening and acceptance was high despite this low awareness rate. Parental awareness appeared to depend on contact with healthcare workers. Community education may increase awareness and demand for UNHS.
Robustness of Poisson Mixture models in identifying risk factors for Under-Five mortality in Nigeria
Authors: Oritogun Kolawole S. , Bamgboye Elijah A.
Published: May 2020

Background: Estimates of Under-Five mortality (U5M) have taken advantage of indirect methods but U5M risk factors have been identified using fixed statistical models with little considerations for the potentials of mixture models. Mixture models such as Poisson-Mixture models exhibit flexibility tendency, which is an attribute of robustness lacking in fixed models. Objective: To examine the robustness of Poisson-Mixture models in identifying reliable determinants of U5M. Methods: The data on 18,855 women used in this study were obtained from the 2008 Nigeria Demographic and Health Survey (NDHS). Six different Poisson-Mixture models namely: Poisson (PO), Zero-Inflated Poisson (ZIP), Poisson Hurdle (PH), Negative Binomial (NBI), Zero-Inflated Negative Binomial (ZINBI) and Negative Binomial Hurdle (NBIH) were fitted separately to the data. The Akaike Information Criteria (AIC) and diagnostic check for normality were used to select robust models. All tests were conducted at p = 0.05. Results: The models and AIC values for U5M were: 38763.47 (PO), 38654.55 (ZIP), 44270.77 (PH), 38526.26 (NBI), 38513.71 (ZINBI) and 44269.30 (NBIH). The PO, ZIP, PH and NBIH met normality test criteria, and the ZIP model was of best fit. The model identified breastfeeding, paternal education, toilet type, maternal education, place of delivery, birth-order and antenatal-visits as significant determinants of U5M at the national level. Conclusion: The Zero-Inflated Poisson model provided the best robust estimates of Under-five Mortality in Nigeria, while maternal education and birth-order were identified as the most important determinants. The Poisson-mixture models are recommended for modelling Under-five Mortality in Nigeria.

Authors: Osonuga IO , Faponle AS , Ezima EN , Adenowo TK , Adelegan AA
Published: May 2020

Background: The leaves of Telfairia occidentalis (locally known as Ugu) are widely consumed as part of a staple in the southern region of Nigeria. Its nutritional benefits include its rich mineral contents and antioxidant properties. It has been suggested that the leaf extracts may affect blood parameters.

Objectives: To investigate the effects of aqueous extracts of T. occidentalis leaves on haematological indices and liver enzymes in rats.

Methods: Twenty-four male Wistar rats weighing between 150g and 200g were used for the study. They were categorized into four groups of six rats each viz: high-dose, medium-dose, low-dose, and control groups. The leaf extract was administered in doses of 300mg/kg, 200mg/kg, and 100 mg/kg, respectively, while the control group received distilled water rather than leaf extracts.

Results: There was a dose-dependent decrease in the concentrations of liver enzymes and an increase in blood parameters. There was a significant difference (p = 0.000) in the mean red blood cells countof the control group (7.5±0.2×1012/L) compared to the low-dose group (9.1±0.1×1012/L), the medium-dose group (11.7±0.2×1012/L) and the high-dose group (13.3±0.2×1012/L).For the liver enzymes, there was a significant decrease in the mean AST levels in the high-dose group (42.8±3.5 IU/L), the medium-dose group (53.7±5.7IU/L) and the low-dose group (68.5±3.5IU/L) were compared to the value for the control group (88.6 ±2.5× 1012/L).

Conclusions: Using an animal model, Telfairia occidentalis may have hepatoprotective and haemopoietic properties.

Indonesian Village Law No. 6/2014 mandates village to be a self-governing community and local self-government. Based on the law, village government conducts governmental administrative business, local development, fostering village societal, and empowering local people. To support the tasks, it is allowed to raise funds from various sources. This paper aims to investigate any problem and possible solutions to strengthen village capacity in order to achieve the village law vision. This research was conducted in Kutai Kartanegara (Kukar) Regency, Indonesia. It used a qualitative approach and the data were collected in several ways, i.e. focus group discussion, interview, secondary data, and observation. The study showed that village governments have no authority to design their own organizations, because the designs are prepared by central and local governments in detail. Moreover, lack of competence among village government staffs and financial dependency also make village governments rely on supports from central and local governments. It concludes that high intervene from upper governments make the village governments have limited room to manage their organizations. Secondly, policy disharmony among ministers also makes them in a dilemma about which one should be followed. Thirdly, various limited upon villages consequently makes them highly depend on supports, especially financial supports, from higher levels of government. Therefore, some actions need to be taken, such as reducing intervention, synchronizing policies among ministries, strengthening village organization and staffs, and optimizing the role of local government agency and stakeholders to take part in the village development process.
Implications of the Decentralization Policy on Poverty Reduction in Indonesia
Authors: Hutahaean Marlan
Published: May 2020

This paper aims to analyze the implications of decentralization policies that are linked to poverty reduction in Indonesia. The focus of the study is the decentralization policy as regulated in Law No. 22/1999, which was amended twice through Law No. 32/2004 and Law No. 23/ 2014 concerning local government. In addition, it also discussed Law No. 25/1999 concerning financial relations in the central-regional government. Using qualitative methods with a policy/program analysis approach and secondary data, this study found that decentralization policies do not link directly to poverty reduction. Out of 34 provincial regions, only 8 provincial regions have achieved a human development index (HDI) above the national average, while having a poverty rate below the national average. In contrast, there are 13 provincial regions that reached HDI below the national average and at the same time have poverty levels above the national average. Based on these findings, this study recommends, first, that local governments evaluate and direct various programs that lead to HDI improvement and poverty reduction. Second, that they synchronize poverty reduction programs in the regions with the same programs from the central government and international programs in the regions.

Published: May 2020

Rapid economic growth in Asia has helped reduce gender inequality in several countries, especially those in Southeast Asia. This has led, among many other things, to the fact that women have higher opportunities to become leaders. Yet, in Southeast Asia the biggest challenge that remains is the tendency of “untrained” women in public leadership. Then the birth of women needs to get strategic support from the current system of leadership culture, that good life for women is the main pillar of women’s leadership requirements. This paper discusses the opportunities present for preparing Southeast Asian women to become future leaders from a number of authentic leader characteristics that they have. By using the content analysis method, the preliminary findings of this study is the existence of better gender relations, accompanied by the resilience and pragmatism of today’s location communities, bringing Southeast Asian women to a promising future leadership role. A number of characteristics of authentic leaders that have become the basis of women’s identity are actually the main capital to be prepared further through a number of educational efforts, assistance and training in order to increase knowledge, insight, organizational skills and self- confidence. Next, women leaders must be made. Women’s willingness and ability to adapt and develop stronger skills in the areas of emotional intelligence, empowerment, and power of influence place them in a strong position to use these advantages to propel them forward in leadership roles. Southeast Asian countries, especially those with a low human development index, have to begin to open up the need for a state led by women leaders who have the potential to represent a number of authentic leadership criteria to respond to the crisis of public confidence in the country’s leadership.
