ABSTRACT

BACKGROUND: The use of a mobile phone-based Interactive Voice Response (mIVR) System for real time monitoring of childhood illnesses provides an opportunity to improve childhood survival and health systems. However, little is known about the factors that facilitate its use. This study sought to identify key determinants and moderators of mIVR system use among caregivers in a rural district of Ghana using the Unified Theory of Acceptance and Use of Technology (UTAUT) model.

METHODS: The mIVR system was designed to provide real-time data on common symptoms of childhood illnesses after answering several questions by caregivers with sick children. A structured questionnaire with closed questions was used to collect data from 354 caregivers of children under-five living in rural communities, four (4) months after introducing the system. Regression analysis was used to identify key determinants and moderating factors that facilitate the use of the system based on the UTAUT model.

RESULTS: A total of 101 (28.5%) caregivers had used the system and 328 (92.7%) had intention to use the mIVR system. Caregivers’ level of education and household wealth were associated with use of the mIVR systems (p<0.001). Behavioural intention (BI) to use mIVR system was positively influenced by performance expectancy (PE) (β = 0.278, 95% CI: 0.207, 0.349), effort expectancy (EE) (β = 0.242, 95% CI: 0.159, 0.326) and social influence (SI) (β = 0.081, 95% CI: 0.044, 0.120). Facilitating conditions (FC) (β = 0.609, 95% CI: 0.502, 0.715) and behavioural intention (β = 0.426, 95% CI: 0.255, 0.597) had a positive influence on user behaviour (UB). Mobile phone experience and household wealth significantly moderated the effect of PE, EE, SI, and FC on behavioural intention and usage of mIVR systems.

CONCLUSION: The perceived usefulness of the mIVR system, ease of use, social influences, and facilitating conditions are key determinants of users’ attitude and use of mIVR system. These relationships are significantly moderated by users’ phone experience and wealth status.

ABSTRACT

BACKGROUND: Caste plays a significant role in Indian society and it influences women to health care access in the community. The implementation of the maternal health benefits scheme in India is biased due to caste identity. In this context, the paper investigates access to Janani Suraksha Yojana (JSY) among social groups to establish that caste still plays a pivotal role in Indian society. Also, this paper aims to quantify the discrimination against Scheduled Castes/Scheduled Tribes (SCs/STs) in accessing JSY.

METHODS: This paper uses a national-level data set of both NFHS-3 (2005-06) and NFHS-4 (2015-16). Both descriptive statistics and the Fairlie decomposition econometric model have been used to measure the explained and unexplained differences in access to JSY between SCs/STs and non-SCs/STs groups.

RESULTS: Overall, the total coverage of JSY in India is still, 36.4%. Further, it is found that 72% of access to JSY is explained by endowment variables. The remaining unexplained percentage (28%) indicates that there is caste discrimination (inequity associated social-discrimination) against SCs/STs in access to JSY. The highest difference (54%) between SCs/STs and non-SCs/STs in access to JSY comes from the wealth quintile, with the positive sign indicating that the gap between the two social groups is widening.

DISCUSSION AND CONCLUSION: It is necessary for the government to implement a better way to counter the caste-based discrimination in access to maternal health benefits scheme. In this regard, ASHA and Anganwadi workers must be trained to reduce the influence of dominant caste groups as well as they must be recruited from the same community to identify the right beneficiaries of JSY and in order to reduce inequity associated with social-discrimination.

ABSTRACT

Health-related quality of life (HRQOL) of kidney transplant recipients is an outcome evaluation after kidney transplants. Therefore, we investigated the associations among perceived health status, social support, self-determination, post-traumatic growth, and kidney transplant recipients’ HRQOL. This study involved a descriptive, self-report survey of 163 kidney transplant recipients visiting an outpatient solid organ transplant center in South Korea. Participants’ general and transplant characteristics, perceived health status, post-traumatic growth, social support, self-determination, and HRQOL were collected. Data were statistically analyzed using the software SPSS version 25.0. HRQOL showed statistically significant positive correlation with perceived health status (r = .56, p < .001), post-traumatic growth (r = .18, p = .022), social support (r = .25, p = .002), and self-determination (r = .36, p < .001). The factors affecting HRQOL were perceived health status (β = 0.47, p < 0.001), post-transplant occupation (β = 0.17, p = 0.009), and income source (β = -0.13, p = 0.046). The explanatory power of these variables was 34.8% (F = 28.81, p < 0.001). In the subdomains of HRQOL, the factors influencing HRQOL of mental component summary were perceived health status (β = 0.45, p < 0.001), self-determination (β = 0.27, p < 0.001), and education level (β = 0.18, p = 0.006). The explanatory power of these variables was 34.8% (F = 28.81, p < 0.001). To promote the HRQOL of kidney transplant recipients, an institutional system to assist kidney transplant recipients in returning to work needs to be developed. Additionally, creating an environment that allows kidney transplant recipients to act with self-determination, and developing intervention programs that can enhance self-determination will contribute to enhancing the HRQOL of kidney transplant recipients.

ABSTRACT

OBJECTIVES: Despite the increasing knowledge about placebo effects and their beneficial impact on treatment outcomes, strategies that explicitly employ these mechanisms remain scarce. To benefit from placebo effects, it is important to gain better understanding in how individuals want to be informed about placebo effects (for example about the underlying mechanisms that steer placebo effects). The main aim of this study was to investigate placebo information strategies in a general population sample by assessing current placebo knowledge, preferences for different placebo explanations (built around well-known mechanisms involved in placebo effects), and attitudes and acceptability towards the use of placebo effects in treatment.

DESIGN: Online survey.

SETTING: Leiden, The Netherlands.

PARTICIPANTS: 444 participants (377 completers), aged 16-78 years.

MAIN OUTCOME MEASURES: Current placebo knowledge, placebo explanation preferences, and placebo attitudes and acceptability.

RESULTS: Participants scored high on current placebo knowledge (correct answers: M = 81.15%, SD = 12.75). Comparisons of 8 different placebo explanations revealed that participants preferred explanations based on brain mechanisms and positive expectations more than all other explanations (F(7, 368) = 3.618, p = .001). Furthermore, attitudes and acceptability for placebos in treatment varied for the type of the condition (i.e. more acceptant for psychological complaints) and participants indicated that physicians do not always have to be honest while making use of placebo effects for therapeutic benefit.

CONCLUSION: Our results brought forth new evidence in placebo information strategies, and indicated that explanations based on brain mechanisms and positive expectations were most preferred. These results can be insightful to construct placebo information strategies for both clinical context and research practices.

ABSTRACT

BACKGROUND: Diabetes mellitus as a chronic metabolic disease is threatening human health seriously. Although numerous clinical trials have been registered for the treatment of diabetes with stem cells, no articles have been published to summarize the efficacy and safety of mesenchymal stem cells (MSCs) in randomized controlled trials (RCTs).

METHODS AND FINDINGS: The aim of this study was to systematically review the evidence from RCTs and, where possible, conduct meta-analyses to provide a reliable numerical summary and the most comprehensive assessment of therapeutic efficacy and safety with MSCs in diabetes. PubMed, Web of Science, Ovid, the Cochrane Library and CNKI were searched. The retrieval time was from establishment of these databases to January 4, 2020. Seven RCTs were eligible for analysis, including 413 participants. Meta-analysis results showed that there were no significant differences in the reduction of fasting plasma glucose (FPG) compared to the baseline [mean difference (MD) = -1.05, 95% confidence interval (CI) (-2.26,0.16), P<0.01, I2 = 94%] and the control group [MD = -0.62, 95%CI (-1.46,0.23), P<0.01, I2 = 87%]. The MSCs treatment group showed a significant decrease in hemoglobin (Hb) A1c [random-effects, MD = -1.32, 95%CI (-2.06, -0.57), P<0.01, I2 = 90%] after treatment. Additionally, HbA1c reduced more significantly in MSC treatment group than in control group [random-effects, MD = -0.87, 95%CI (-1.53, -0.22), P<0.01, I2 = 82%] at the end of follow-up. However, as for fasting C-peptide levels, the estimated pooled MD showed that there was no significant increase [MD = -0.07, 95%CI (-0.30, 0.16), P<0.01, I2 = 94%] in MSCs treatment group compared with that in control group. Notably, there was no significant difference in the incidence of adverse events between MSCs treatment group and control group [relative risk (RR) = 0.98, 95%CI (0.72, 1.32), P = 0.02, I2 = 70%]. The most commonly observed adverse reaction in the MSC treatment group was hypoglycemia (29.95%).

CONCLUSIONS: This meta-analysis revealed MSCs therapy may be an effective and safe intervention in subjects with diabetes. However, due to the limited studies, a number of high-quality as well as large-scale RCTs should be performed to confirm these conclusions.

ABSTRACT

INTRODUCTION: Hepatitis B virus (HBV) infection is hyper-endemic in Nigeria. Prisons are high-risk environments for the spread of infectious diseases. Worldwide, seroprevalence of HBV infection is substantially higher among individuals in correctional facilities when compared to general population. We determined the seroprevalence and risk factors associated with HBV infection among Kuje prison inmates, Nigeria.

MATERIAL AND METHODS: We conducted a prison facility based cross-sectional study. Interviewer administered questionnaires were used to obtain information on participants socio-demographic characteristics, HBV risk factors, previous HBV test and vaccination history. Blood samples collected from participants were analysed for HBsAg, HBsAb, HBcAb, HBeAg and HBeAb markers using rapid lateral chromatographic immunoassay kit. Univariate, bivariate, and multivariate analysis were performed.

RESULTS: A total of 271 inmates (63 convicts and 208 awaiting trial inmates) were recruited into the study as participants. The mean age of the participants was 32.7 SD±9 years. HBV seroprevalence (HBsAg) of 13.7% (95% CI: 9.8-18.3) was found. 55.4% (95% CI: 49.2-61.4) of inmates were susceptible to HBV infection, 20.7% (95%CI; 16.0-26.0) had past HBV infection while 10.3% (95% CI: 7.0-14.6) had acquired natural or artificial HBV immunity. Factors found to be associated with current HBV infection (HBsAg) include age-group ≤25years (aOR = 8.0,95% CI: 2.9-22.3), being ever married (aOR = 4.2, 95% CI: 1.7-10.4) and history of alcohol consumption (aOR = 3.4, 95% CI: 1.3-8.4).

CONCLUSION: This study reveals a high seroprevalence of HBV infection among Kuje Prison inmates, hence the need to introduce prison-focused health intervention initiatives such as HBV screening, vaccination and care to reduce the transmission of HBV infection among inmates and ultimately the general population.

ABSTRACT

BACKGROUND: Small cell lung cancer (SCLC) is a highly malignant lung cancer with a very poor prognosis. Clinical treatment options for SCLC are still limited, especially for patients who have failed first or second line therapy. Anlotinib is a potentially beneficial new treatment option for SCLC. The aim of this meta-analysis is to evaluate the efficacy and safety of anlotinib-containing regimen for the treatment of SCLC.

METHODS: We will search SinoMed, Wanfang Database, China National Knowledge Infrastructure, Embase, Cochrane Library, and PubMed for relevant articles that may meet the criteria published before March 31, 2021. We will perform a meta-analysis to evaluate the efficacy and safety of anlotinib-containing regimen for the treatment of SCLC. Clinical randomized controlled trials comparing anlotinib-containing regimens with other treatment regimens for advanced SCLC will be included in this study. The risk of bias will be evaluated for each included study using the Cochrane Handbook for Systematic Reviews of Interventions. We will use RevMan 5.3 software for statistical analysis of the data.

RESULTS: The results of this study will provide evidence of anlotinib-containing regimens for advanced SCLC, and provide clinicians and patients with another convenient and effective treatment regimen for SCLC. This meta-analysis will be submitted to a peer-reviewed journal for publication.

CONCLUSION: This meta-analysis will provide clinical evidence of anlotinib-containing regimens for advanced SCLC, which may or may not be found for anlotinib use.

ABSTRACT

BACKGROUND: Previous studies have suggested that processing of visual contrast information could be altered in major depressive disorder. To clarify the changes at different levels of the visual hierarchy, we behaviourally measured contrast perception in 2 centre-surround conditions, assessing retinal and cortical processing.

METHODS: As part of a prospective cohort study, our sample consisted of controls (n = 29; 21 female) and patients with unipolar depression, bipolar disorder and borderline personality disorder who had baseline major depressive episodes (n = 111; 74 female). In a brightness induction test that assessed retinal processing, participants compared the perceived luminance of uniform patches (presented on a computer screen) as the luminance of the backgrounds was varied. In a contrast suppression test that assessed cortical processing, participants compared the perceived contrast of gratings, which were presented with collinearly or orthogonally oriented backgrounds.

RESULTS: Brightness induction was similar for patients with major depressive episodes and controls (p = 0.60, d = 0.115, Bayes factor = 3.9), but contrast suppression was significantly lower for patients than for controls (p < 0.006, d = 0.663, Bayes factor = 35.2). We observed no statistically significant associations between contrast suppression and age, sex, or medication or diagnostic subgroup. At follow-up (n = 74), we observed some normalization of contrast perception.

LIMITATIONS: We assessed contrast perception using behavioural tests instead of electrophysiology.

CONCLUSION: The reduced contrast suppression we observed may have been caused by decreased retinal feedforward or cortical feedback signals. Because we observed intact brightness induction, our results suggest normal retinal but altered cortical processing of visual contrast during a major depressive episode. This alteration is likely to be present in multiple types of depression and to partially normalize upon remission.

ABSTRACT

CONTEXT: Students enrolled in health professional (HP) programs receive varying amounts of credit hours dedicated to nutritional education, and obesity remains an issue in the United States among healthcare providers.

OBJECTIVES: To assess whether HP students differ in nutrition and exercise habits from non-health professional (NHP) students at a single university, and whether any gender-related differences existed in those habits.

METHODS: From September 25, 2018 to October 10, 2019, a 16-question multiple-choice survey was distributed via e-mail or in person to HP and NHP students enrolled at Nova Southeastern University (NSU) in Fort Lauderdale, Florida. Questions targeted participant dietary and exercise habits. Each question had five multiple-choice answer options, each of which was assigned a coded value to compare similarities and differences between the HP and NHP groups.

RESULTS: Of 732 responses (569 HP, 163 NHP), results showed no statistically significant difference between enrollment groups (p>0.05) in any response parameter including consumption of sweets, fast food, red meat, caffeine, water, fruit, and vegetables. Comparisons among sexes demonstrated significant differences. Women consumed less red meat, water, and protein, and women participated in less exercise compared to men. Women also consumed more sweets compared to men.

CONCLUSIONS: Results suggest that NSU students enrolled in HP and NHP programs have similar nutritional concepts and eating habits. This may indicate a need to strengthen nutritional education in dietary health and wellness for HP students.

ABSTRACT

CONTEXT: Under the Accreditation for Graduate Medical Education (ACGME) single accreditation system, there is likely to be increasing interest and opportunity for teaching osteopathic manipulative treatment (OMT) to allopathic residents and residency faculty. When learning OMT, allopathic physicians (MDs) have distinct needs compared with osteopathic medical students. For example, MDs already have a foundation in anatomy and medical vocabulary, but incorporating an osteopathic approach to patient care may require a paradigm shift. Thus, a unique approach to osteopathic education for MDs in residency programs with osteopathic recognition (OR) is needed.

OBJECTIVE: To create a longitudinal OMT elective for allopathic residents and residency faculty and assess its impact on attitudes and confidence regarding osteopathic principles and treatment.

METHODS: Drawing from standard texts used during preclinical osteopathic education, a blended online and in-person laboratory modular curriculum for the OMT elective course was developed by osteopathic residents and faculty within the Department of Family Medicine and Community Health at the University of Wisconsin in Madison. The modalities of muscle energy, counterstrain, myofascial release, and soft tissue were included; the curriculum also reviewed autonomic physiology, somatovisceral, and viscerosomatic reflexes. A quality improvement study of the course was conducted via pre- and postcourse surveys to assess its impact on perceptions and confidence regarding the theory and practice, referral, and use of OMT. A precourse survey was distributed before the first module to obtain background information and assess participants’ prior OMT exposure, among other things. Nine months after the course ended, a corresponding postcourse survey was distributed. Pre- and postcourse surveys were individually matched to improve statistical analysis, using unique identifiers. Also, following each laboratory, a postlaboratory survey was collected about the participant’s experience for that lecture and for laboratory-specific quality improvement purposes. Two years after course completion, graduates were reached via phone or email for informal interviews to assess the perceived long-term impact from the elective.

RESULTS: Eleven MDs from a total potential pool of 26 residents and approximately 120 attending physicians enrolled in the course; eight (72.7%) completed all modules and pre- and postcourse evaluations. Participants reported statistically significant gains in attitudes and confidence regarding OMT (“knowledgeable regarding OMT principles”: precourse mean, 2.50 [0.76], vs. postcourse mean, 3.37 [0.52]; p=0.021; “know how to treat using OMT”: precourse mean, 2.25 [1.39], vs. postcourse mean, 3.12 [1.25]; p=0.041). Several participants (five; 62.5%) had completed prior OMT training. There was an increase, albeit nonsignificant, in the use of OMT, with more providers using OMT (precourse mean, five, vs. postcourse mean, six; p=0.171), and providers using OMT more often (precourse OMT use monthly or more often, three, vs. postcourse OMT use monthly or more often, six; p=0.131).

CONCLUSION: Implementing a longitudinal elective curriculum is a feasible way to improve attitudes and confidence in OMT for MDs involved in a family medicine residency. Whether our elective leads to competency in OMT for allopathic residents and faculty remains to be formally evaluated. Our pilot established the feasibility and led to a revision of our curriculum; the elective continues to occur yearly. Future analyses will focus on competency assessment.
