The use of 'PICO for synthesis' and methods for synthesis without meta-analysis: protocol for a survey of current practice in systematic reviews of health interventions

Exploring the impacts of perceived locus of control on post-traumatic stress disorder among disaster survivors: A systematic review

WHAT IS KNOWN ON THE SUBJECT?: It was previously reported that perceived external locus of control may exacerbate depressive symptoms, is associated with anxiety, boosts stress and general mental distress and weakens resilience against traumatic situations or difficulties. WHAT THE PAPER ADDS TO EXISTING KNOWLEDGE?: Those with a higher external locus of control are more prone to develop PTSD symptoms since the perceived external locus of control is among the predictors of PTSD. An internal locus of control is considered important in preventing PTSD, although an external locus of control appears to be a variable that causes/increases the prevalence of PTSD. WHAT ARE THE IMPLICATIONS FOR PRACTICE?: It is known that nurses are deployed in clinical and fieldwork during disaster and assume key roles both interventional practices and psychosocial education. Thus, it is of particular importance for mental health nurses to be aware of the locus of control in themselves, their colleagues, and the community before, during and after disasters to be able to combat the risk/presence of PTSD.

ABSTRACT

AIM: The present systematic review explored the impacts of perceived locus of control on PTSD among individuals experiencing disasters.

METHOD

This is a systematic review study carried out through a search of the relevant research published in English over the period December 2021 to April 2022. Accordingly, we sought the studies to review on the Web of Science, PubMed, Scopus, Cochrane and Google Scholar databases using the keywords "Child, Children, Adolescent, Adolescence, Adult, Aged, Elderly, Post-Traumatic Stress Disorder, PTSD, Internal-External Control, Locus of Control, Disasters, Natural Disasters."

RESULTS

A total of 1.011 studies were found in the five databases using the keywords above. Following the exclusions, the remaining six studies were recruited for this systematic review. The six studies in question addressed earthquakes (2), hurricanes (1), wildfires (1), SARS (1) and fireworks explosions (1). In the study with wildfire survivors, there was a weak significant association between external locus of control and PTSD among those directly exposed to the disaster (r = .15, p < .01). The study with survivors of the SARS epidemic demonstrated that those with a high perceived chance (external) locus of control suffered PTSD (p = .001). An internal locus of control is considered important in preventing PTSD, although an external locus of control appears to be a variable that causes/increases the prevalence of PTSD.

CONCLUSION

It was concluded that perceived locus of control is related to PTSD in individuals experiencing a disaster. The additional evidence was that post-disaster PTSD among those with a high perceived external locus of control is stronger than those with a high perceived internal locus of control.

Glutathione S-transferase theta 1 (GSTT1) deletion polymorphism and susceptibility to head and neck carcinoma: a systematic review with five analyses

Glutathione S-transferase theta 1 (GSTT1) enzyme plays a key role in the neutralization of electrophilic compounds such as carcinogens. Herein, we aimed to evaluate GSTT1 deletion polymorphism and susceptibility to head and neck carcinoma (HNC) according to 107 articles in a systematic review with five analyses. The databases of PubMed/Medline, Web of Science, Scopus, and Cochrane Library from the beginning of each database until June 21, 2023, with no restrictions to identify pertinent articles. The RevMan 5.3 software was used to calculate the effect sizes, which were displayed as the odds ratio (OR) along with a 95% confidence interval (CI). Both the publication bias and sensitivity analyses were performed using the CMA 3.0 software. A trial sequential analysis (TSA) was conducted. Of the 1966 records retrieved from four databases, 107 articles were included in the analysis. The combined analysis revealed that the pooled OR was 1.28 (95% CI: 1.14 to 1.44; p-value < 0.0001). The pooled OR was highest in mixed ethnicity. Nasopharyngeal cancer had the highest OR (1.84), followed by oral cancer (OR = 1.20), and laryngeal cancer (OR = 1.17). Studies with less than 200 samples had a higher OR compared to those with 200 or more samples. The studies with a quality score of 7 or more had a higher OR compared to those with a score of less than 7. When both age and sex are considered, while the OR of 1.42 is significant, the high heterogeneity suggests caution in interpreting these results. There is no evidence of publication bias. TSA reported that the study does not have sufficient statistical power. This comprehensive meta-analysis revealed a significant association between the GSTT1 null genotype and an increased risk of HNC, with variations based on factors such as ethnicity, cancer type, sample size, control source, and quality score.

Risk Factors, Complications, and Treatment Modalities for Sudden Sensorineural Hearing Loss in Pregnant Women: A Systematic Review and Meta-analysis

BACKGROUND

Sudden sensorineural hearing loss (SSNHL) during pregnancy is a rare condition and has not been much studied. The study aimed to perform a systematic review and meta-analysis of the risk factors, complications, and treatment modalities for SSNHL in pregnant women.

MATERIALS AND METHODS

PubMed, Web of Science, Scopus, ProQuest, and Google Scholar were used for the literature search. The Cochrane technique for assessing risk of bias was used for the article quality appraisal, and RevMan 5.4 was used for conducting the meta-analysis. Standard mean difference (SMD) and odds ratios with a 95% confidence interval (95% CI) were utilized. Heterogeneity and publication bias were assessed using the I-square (I2) test statistic and the Egger's test, respectively.

RESULTS AND DISCUSSION

The seven primary studies employed prospective and retrospective study designs. The meta-analysis showed that there were fewer risk variables for SSNHL in the experimental group compared with those in the control group (SMD = -0.45 to 3.24, 95% CI = -3.063.63 to 2.16-2.85), indicating that the analysis revealed an insignificant difference. However, the treated patients presented hearing improvement, suggesting a significant analysis (SMD = -0.6710.20, 95% CI = -1.2713.51 to -0.066.88). Furthermore, after therapy, substantial differences were observed in SMD between the two groups (SMD = -0.7415.18, 95% CI = -1.2423.85 to -0.256.40) in favor of the experimental group patients, based on the analysis results of four included studies. However, the I2-value of 0% showed that the heterogeneity was low.

CONCLUSION

SSNHL during pregnancy is a notably rare condition with an unknown cause. However, hormonal fluctuations, particularly increased levels of estrogen and progesterone during pregnancy, have been frequently implicated as potential triggers for SSNHL.

Trends and ethical issues in nursing during disasters: A systematic review

BACKGROUND

During a disaster, nurses face complex ethical challenges because of risky situations. It is necessary to identify trends and ethical issues of nurses in disasters to improve the quality of care and impact for nurses.

METHOD

This systematic review enrolled in the international registration with PROSPERO: CRD42022350765. We searched the following databases: PubMed, EBSCO MEDLINE, SCOPUS, ProQuest, ScienceDirect, and Sage Pub. The inclusion criteria were developed according to PICO and D; are Population (F): involving nurses; intervention/Exposure (I): disaster, Comparison (C): none; outcome (O): ethical practice. And Design (D): qualitative, quantitative, and mixed methods. Years of publication were 2012-2022, with full text in English. The quality of study assessment used was The Joanna Briggs Institute (JBI) Critical Appraisal tool and Mixed Methods Appraisal Tool (MMAT) version 2018. Analysis used PICO synthesis.

RESULTS

There were 15 studies reviewed from 2093 results, including cross-sectional (4/15, 26.6%), qualitative (9/15, 60%), and mixed methods (2/15, 13.3%) studies. The types of disasters were: COVID-19 (7/15, 46.6%), infectious (4/15, 26.6%), and all disaster events (4/15, 26.6%). The main themes were: (1) ethical issues in disasters have the potential to address ethical dilemmas, (2) factors applying nursing ethics to support ethical decision-making in disasters, (3) strategies for applying ethics and dealing with ethical issues in disasters, and (4) the impact of applying ethics in disasters.

CONCLUSION

Applying ethics nursing in a disaster is influenced by various factors. This framework for ethical nursing in disasters aims to help nurses, educational institutions, and policymakers develop schemes or scenarios to enhance responsible ethical decisions in disasters.

Use of Iontophoresis with Corticosteroid in Carpal Tunnel Syndrome: Systematic Review and Meta-Analysis

BACKGROUND

Carpal tunnel syndrome is a neuropathy that affects the median nerve. The aim of this review is to synthesize the evidence and perform a meta-analysis on the effects of iontophoresis in people with carpal tunnel syndrome.

METHODS

The search was carried out using PubMed, Web of Science, Scopus, CINHAL Complete, Physiotherapy Evidence Database, and SciELO. The methodological quality was evaluated using PEDro. A standardized or mean difference meta-analysis (Hedge's g) using a random-effects model was calculated.

RESULTS

Seven randomized clinical trials using iontophoresis for electrophysiological, pain, and functional outcomes were included. The mean of PEDro was 7/10. No statistical differences were obtained for the median sensory nerve conduction velocity (SMD = -0.89; p = 0.27) or latency (SMD = -0.04; p = 0.81), motor nerve conduction velocity (SMD = -0.04; p = 0.88) or latency (SMD = -0.01; p = 0.78), pain intensity (MD = 0.34; p = 0.59), handgrip strength (MD = -0.97; p = 0.09), or pinch strength (SMD = -2.05; p = 0.06). Iontophoresis only seemed to be superior in sensory amplitude (SMD = 0.53; p = 0.01).

CONCLUSIONS

Iontophoresis did not obtain an enhanced improvement compared to other interventions, but no clear recommendations could be made due to the limited number of included studies and the heterogeneity found in the assessment and intervention protocols. Further research is needed to draw sound conclusions.

Phonophoresis through Nonsteroidal Anti-Inflammatory Drugs for Knee Osteoarthritis Treatment: Systematic Review and Meta-Analysis

Knee osteoarthritis (OA) is the most common joint disease. The administration of nonsteroidal anti-inflammatory drugs (NSAIDs) by phonophoresis is a therapeutic alternative to relieve pain in inflammatory pathologies. The main aim was to analyze the efficacy of the application of NSAIDs by phonophoresis in knee OA. A systematic review and meta-analysis of controlled clinical trials were performed between January and March 2021 in the following databases: Web of Science, Scopus, PubMed, Cinahl, SciELO, and PEDro. The PEDro scale was used to evaluate the level of evidence of the selected studies. The RevMan 5.4 statistical software was used to obtain the meta-analysis. Eight studies were included, of which five were included in the meta-analysis, involving 195 participants. The NSAIDs used through phonophoresis were ibuprofen, piroxicam, diclofenac sodium, diclofenac diethylammonium, ketoprofen, and methyl salicylate. The overall result for pain showed not-conclusive results, but a trend toward significance was found in favor of the phonophoresis group compared to the control group (standardized mean difference (SMD) = -0.92; 95% confidence interval: -1.87-0.02). Favorable results were obtained for physical function (SMD = -1.34; 95% CI: -2.00-0.68). Based on the selected studies, the application of NSAIDs by phonophoresis is effective in relieving the symptoms of knee OA. Future long-term studies are recommended.

The effect of family-centered empowerment model on the quality of life of adults with chronic diseases: An updated systematic review and meta-analysis

BACKGROUND

Family-centered empowerment model (FCEM) is a concept that strengthens the family to help a chronic patient to obtain a better quality of life (QoL). The effects of FCEM on QoL of chronic patients are still inconclusive. Therefore, this meta-analysis was conducted to evaluate the effect of FCEM on QoL of adult patients with chronic diseases.

METHODS

Following an online search PubMed/MEDLINE, Scopus, Web of Science, ProQuest, OVID, EMBASE, EBSCO, PsycINFO and Persian databases (Irandoc, IranMedex, SID and MagIran), all studies that tested the impact of FCEM on QoL of patients with chronic diseases were included. Cochrane Risk of Bias Tool was used to assessment the quality of included randomized clinical trials (RCTs) and before/after studies. Analyses were conducted by STATA16.

RESULTS

Six hundred and ninety-seven studies were identified for screening. After screening process, 11 eligible studies were included in this meta-analysis. There were significant intervention effects in all QoL dimensions, physical and mental subscales and QoL total score (All P < 0.05). The minimum lower bound for SMD was 0.61 (95%CI: 0.96 to 1.66), indicating an increasing effect of the intervention on all QOL dimensions. The results showed substantial heterogeneity between the studies for all QoL dimensions, physical and mental subscales and QoL total scores (P < 0.001).

CONCLUSION

FCEM is an appropriate model with a simple and effective application for families with a patient suffering from a chronic illness. Nursing education planners and healthcare providers could benefit from this model for improving the nursing education curriculum and accrediting programs.

Use of Sonophoresis with Corticosteroids in Carpal Tunnel Syndrome: Systematic Review and Meta-Analysis

Carpal tunnel syndrome is a neuropathic disease. It is one of the most frequent musculoskeletal pathologies affecting the upper limbs. One of most frequently used non-surgical treatments is corticosteorids. There are several alternatives for corticosteroids administration. One of them is phonophoresis, this being an effective and painless method of treatment. A systematic review and meta-analysis have been conducted over the use of phonophoresis with corticosteroids for the treatment of carpal tunnel syndrome compared to other non-surgical treatment methods. Keywords from Medical Subjects Headings (MeSH) were used in the following databases: Wos, Scopus, CINHAL, SciELO and PeDro. A total of 222 potentially relevant articles were retrieved. Eleven articles analysing the efficacy of phonophoresis with corticosteroids in reducing pain symptoms in individuals with carpal tunnel syndrome were included, 10 of which were used to conduct the meta-analysis. A conclusion could not be reached as to the application of phonophoresis with corticosteroids being better than other treatment methods, except for the perception of pain and an improved motor and sensory nerve conduction in cases of mild to moderate carpal tunnel syndrome.

Physical activity and sedentary behaviour in shift and non-shift workers: A systematic review and meta-analysis

Research examining the prevalence, physical activity (PA) and sedentary behaviour (SB) in shift workers show mixed results. This systematic review and meta-analysis aimed to compare PA and SB in shift workers with non-shift workers following the PRISMA guidelines. Ebscohost megafile ultimate (CINHAL, E-journals, Academic search ultimate, health source consumer edition, SPORT Discus), PubMed, Scopus, Web of Science, and Science Direct databases were searched up to April 2021. Cross-sectional and baseline data from longitudinal studies reporting PA and SB in full time workers were eligible. Data on participants characteristics and time spent in PA and SB and/or prevalence of workers meeting PA guidelines were extracted and pooled with random effects model. The Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) 10-item checklist was adapted and used. A total of 49 studies met inclusion criteria and 21 studies included for meta-analysis. The prevalence of meeting physical activity guidelines (OR 0.84, 95% CI: 0.68, 1.03) and standardized mean difference (SMD) of time spent in moderate-to-vigorous physical activity (SMD -0.1, 95% CI: -0.4, 0.20) were similar in shift and non-shift workers. Time spent in sedentary behaviour was lower in shift workers than non-shift workers (SMD -0.2, 95% CI: 0.50, -0.001). While the differences in PA are not so evident between shift and non-shift workers, the prevalence of sufficient PA was low in both groups. These preliminary findings provide support for inclusion of physical activity and sedentary behaviour in health promotion interventions targeted at shift workers.
