Self-Stigma Reduction Interventions for People Living with HIV/AIDS and Their Families: A Systematic Review

Stigma is a primary concern for people living with human immunodeficiency virus (HIV)/AIDS (PLWHA), and has great impact on their and their family members' health. While previous reviews have largely focused on the public stigma, this systematic review aims to evaluate the impact of HIV/acquired immunodeficiency syndrome (AIDS)-related self-stigma reduction interventions among PLWHA and their families. A literature search using eight databases found 23 studies meeting the inclusion criteria. Five types of intervention approaches were identified: (1) psycho-educational intervention, (2) supportive intervention for treatment adherence (antiretroviral therapy), (3) psychotherapy intervention, (4) narrative intervention, and (5) community participation intervention. Overall, the reviewed articles suggested a general trend of promising effectiveness of these interventions for PLWHA and their family members. Psycho-educational interventions were the main approach. The results highlighted the need for more interventions targeting family members of PLWHA, and mixed-methods intervention studies.

Conflicting identities between sex workers and motherhood: A systematic review

Being a mother is a traditional and central role for women. However, due to criminalization, social stigma and marginalized lifestyles, female sex workers (FSWs) may encounter disadvantages and social inequality. The aim of this review was to synthesize the results of studies focused on the challenges that FSWs face in negotiating their maternal identity with their stigmatized identity as sex workers. A total of 21 studies published from 2002 to 2016 were included in this review. Textual narrative and a thematic synthesis approach were adopted to synthesize key themes. Two common themes across countries were identified: conflicting identities between the jobs as sex workers and motherhood and responses to social expectations of ideal motherhood. Given the challenges that FSWs face with motherhood, comprehensive services, including health, family, social, and legal services, are needed to support FSWs as individuals and as mothers. A more holistic approach is recommended to address their physical, emotional, financial, and social problems faced by FSWs. Services should be offered in a friendly and non-judgmental manner. Further, to advance the health and safety of FSWs and their children, prostitution law may need to move toward decriminalization of sex work and educate the general public about respecting FSWs.

The Socio-Ecological Model Approach to Understanding Barriers and Facilitators to the Accessing of Health Services by Sex Workers: A Systematic Review

Inequities in accessing health care persist among sex workers. The purpose of the review is to understand the health-seeking behaviours of sex workers and their access to health care services with socio-ecological model. Of 3852 citations screened, 30 met the inclusion criteria for this review. The access that sex workers have to health services is a complex issue. A wide range of barriers and facilitators at multiple levels could influence sex workers' utilization of health care services, such as health or service information, stigma, social support, quality of health care, available, accessible and affordable services, healthcare policy. Health services or future intervention studies should take into account the facilitators and barriers identified in this review to improve the health services utilization and health of sex workers, as part of the effort to protect the right of humans to health.

Chinese Herbal Medicine and Salmeterol and Fluticasone Propionate for Chronic Obstructive Pulmonary Disease: Systematic Review and Network Meta-Analysis

Among Chinese populations worldwide, Chinese herbal medicines (CHMs) are often used as an adjunct to pharmacotherapy in managing chronic obstructive pulmonary disease (COPD). However, the relative performance among different CHM is unknown.The aim of this study was to evaluate comparative effectiveness of different CHM when used with salmeterol and fluticasone propionate (SFP), compared with SFP alone.This study is a systematic review of randomized controlled trials (RCTs) with network meta-analyses (NMAs).Eight electronic databases were searched. Data from RCTs were extracted for random effect pairwise meta-analyses. Pooled relative risk (RR) with 95% confidence interval (CI) was used to quantify the impact of CHM and SFP on forced expiratory volume in 1 second (FEV1), St George's Respiratory Questionnaire (SGRQ) scoring, and 6-Minute Walk Test (6MWT). NMA was used to explore the most effective CHM when used with SFP.Eleven RCTs (n = 925) assessing 11 different CHM were included. Result from pairwise meta-analyses indicated favorable, clinically relevant benefit of CHM and SFP on FEV1 [7 studies, pooled weighted mean difference (WMD) = 0.20 L, 95% CI: 0.06-0.34 L], SGRQ scoring (5 studies, pooled WMD = -4.99, 95% CI: -7.73 to -2.24), and 6MWT (3 studies, pooled WMD = 32.84 m, 95% CI: 18.26-47.42). Results from NMA showed no differences on the comparative effectiveness among CHM formulations for improving FEV1. For SGRQ, NMA suggested that Runfeijianpibushen decoction and Renshenbufei pills performed best. Use of CHM on top of SFP can provide clinically relevant benefit for COPD patients on FEV1 and SGRQ. Additional use of Runfeijianpibushen decoction and Renshenbufei pills showed better effect on improving SGRQ.Use of CHM and SFP may provide clinically relevant benefit for COPD patients on FEV1, SGRQ, and 6MWT. Use of different CHM formulae included in this NMA showed similar effect for increasing FEV1, while the additional use of Runfeijianpibushen formula and Renshenbufei Pills showed better effect on improving SGRQ. Well conducted, adequately powered trials are needed to confirm their effectiveness in the future.

Indacaterol for chronic obstructive pulmonary disease: systematic review and meta-analysis

BACKGROUND

Inhaled bronchodilators are the first-line therapy for COPD. Indacaterol is a novel addition to existing long-acting bronchodilators.

OBJECTIVES

Systematic review of randomized controlled trials (RCT) ON efficacy and safety of indacaterol as compared: 1) with placebo at different dosages, 2) with existing bronchodilators; (3) as add-on treatment to tiotropium.

METHODS

We searched 13 electronic databases, including MEDLINE, EMBASE and CENTRAL, and contacted the manufacturer for unpublished data. Primary outcome was mean FEV1 change at 12(th) week, secondary outcomes included changes in SGRQ, TDI and BODE index at 6 months, exacerbation at 1 year, and worsening of symptoms.

RESULTS

Twelve eligible RCTs of moderate risk of bias included data from 10,977 patients. Compared to placebo, indacaterol improved FEV1 by a weighted mean difference (WMD) of 0.16 L (95%CI: 0.15, 0.18 L, p<0.001), homogeneously above the minimally important difference of 0.10 L. It offered clinically relevant improvement in all secondary outcomes except exacerbation. Magnitude of benefit did not differ significantly by dosage, but one treatment related death was reported at 300 ug. Efficacy of Indacaterol was similar to formoterol and salmeterol (FEV1 WMD = 0.04 L, 95%CI: 0.01 L, 0.07 L, p = 0.02); and tiotropium (FEV1 WMD = 0.01 L, 95%CI: -0.01, 0.03 L, p = 0.61). The use of indacaterol on top of tiotropium yielded additional improvement on FEV1 (WMD = 0.07 L, 95%CI: 0.05 L, 0.10 L, p<0.001).

CONCLUSION

Indacaterol is safe and beneficial for patients with COPD at dosage ≤150 ug. It may serve as a good alternative to existing bronchodilators, or as an add-on to tiotropium for unresponsive patients. Use of higher dosage requires further justification.

Mycophenolate mofetil for primary focal segmental glomerulosclerosis: systematic review

BACKGROUND

Current treatments for primary focal segmental glomerulosclerosis (FSGS), including corticosteroids and cyclosporine, are not satisfactory for all patients and may induce significant side effects. Antidotal benefits of mycophenolate mofetil (MMF) as an add-on to these immunosuppressive therapies have been reported. This review aims to systematically summarize the efficacy and safety of MMF as a treatment for primary FSGS.

METHOD

Controlled and uncontrolled clinical trials evaluating the use of MMF in primary FSGS patients were identified from nine electronic databases and four clinical trial registries. Kidney failure was selected as the primary outcome.

RESULTS

Three randomized controlled trials (RCT) and 18 uncontrolled pre-post studies were included. Results from RCTs revealed that MMF is no more effective than cyclosporine or cyclophosphamide for promoting kidney function preservation when corticosteroid is used as baseline treatment. One underpowered RCT reported that MMF provides no extra benefit on top of prednisolone, but the result is unlikely to be reliable. Amongst the small, uncontrolled pre-post studies, three of them used MMF as monotherapy, two of which reported successful prevention of kidney failure in all patients. The remaining 15 uncontrolled studies used MMF as add-on therapy and 11 reported kidney failure as an outcome. Amongst them, eight reported no patients developed kidney failure. MMF was generally well tolerated with mild adverse effects, including abdominal discomfort, diarrhea and infections.

CONCLUSIONS

MMF tended to show beneficial effects in uncontrolled studies which recruited patients with resistance to routine treatments, but such favorable results have only been reported in small, uncontrolled trials. No RCT results suggested that MMF was a good alternative to cyclosporine or cyclophosphamide. The role of MMF as an add-on to current therapies, or as monotherapy, should further be evaluated.

Organizational determinants of interprofessional collaboration in integrative health care: systematic review of qualitative studies

Context

Inteprofessional collaboration (IPC) between biomedically trained doctors (BMD) and traditional, complementary and alternative medicine practitioners (TCAMP) is an essential element in the development of successful integrative healthcare (IHC) services. This systematic review aims to identify organizational strategies that would facilitate this process.

Methods

We searched 4 international databases for qualitative studies on the theme of BMD-TCAMP IPC, supplemented with a purposive search of 31 health services and TCAM journals. Methodological quality of included studies was assessed using published checklist. Results of each included study were synthesized using a framework approach, with reference to the Structuration Model of Collaboration.

Findings

Thirty-seven studies of acceptable quality were included. The main driver for developing integrative healthcare was the demand for holistic care from patients. Integration can best be led by those trained in both paradigms. Bridge-building activities, positive promotion of partnership and co-location of practices are also beneficial for creating bonding between team members. In order to empower the participation of TCAMP, the perceived power differentials need to be reduced. Also, resources should be committed to supporting team building, collaborative initiatives and greater patient access. Leadership and funding from central authorities are needed to promote the use of condition-specific referral protocols and shared electronic health records. More mature IHC programs usually formalize their evaluation process around outcomes that are recognized both by BMD and TCAMP.

Conclusions

The major themes emerging from our review suggest that successful collaborative relationships between BMD and TCAMP are similar to those between other health professionals, and interventions which improve the effectiveness of joint working in other healthcare teams with may well be transferable to promote better partnership between the paradigms. However, striking a balance between the different practices and preserving the epistemological stance of TCAM will remain the greatest challenge in successful integration.

Views on traditional Chinese medicine amongst Chinese population: a systematic review of qualitative and quantitative studies

BACKGROUND

Health-care professionals worldwide have started to appreciate patients' perspectives on the use of complementary and alternative medicine (CAM) particularly given its popularity. However, cultural perspectives may vary and it may not be possible to apply research findings on the use of CAM from the west to the east.

OBJECTIVE

This systematic review aims to synthesize usage patterns of traditional Chinese medicine (TCM) amongst Chinese populations in different parts of the world and explore potential geographical variations.

SEARCH STRATEGY

Six international and four Chinese databases were searched, and manual searches of relevant monographs and government publications were carried out.

INCLUSION CRITERIA

Quantitative, qualitative or mixed-method research that aimed to investigate Chinese patients' perception of, and perspectives on, TCM was included.

DATA EXTRACTION AND SYNTHESIS

For each study included, texts under the headings of 'results' or 'findings' were extracted and subjected to analysis. A thematic synthesis approach was adopted for synthesizing qualitative and quantitative studies.

MAIN RESULTS

Amongst the 28 studies included, twenty were quantitative surveys, six were qualitative studies and two were mixed-method studies. The overall methodological quality was mediocre. Data synthesis suggested that patients from all regions share a common cultural affinity to TCM and consider it to be an effective complement to western medicine (WM) for treating chronic or serious diseases. However, heterogeneous views on (i) disclosing TCM use to WM doctors and (ii) the potential harm of herbs emerged across different study locations.

DISCUSSION AND CONCLUSIONS

Future research should explore how variation in health systems may influence patients' perception of CAM in different countries.
