Review Meta-Analysis
Lymphatic filariasis is a neglected tropical disease that affects the lymphatic system of humans. The major etiologic agent is a nematode called Wuchereria bancrofti, but Brugia malayi and Brugia timoriare sometimes encountered as causative agents. Mosquitoes are the vectors while humans the definitive hosts respectively. The burden of the disease is heavier in Nigeria than in other endemic countries in Africa. This occurs with increasing morbidity and mortality at different locations within the country, the World Health Organization recommended treatments for lymphatic filariasis include the use of Albendazole (400mg) twice per year in co-endemic areas with loa loa, Ivermectin (200mcg/kg) in combination with Albendazole (400mg) in areas that are co-endemic with onchocerciasis, ivermectin (200mcg/kg) with diethylcarbamazine citrate (DEC) (6mg/kg) and albendazole (400mg) in areas without onchocerciasis. This paper covered a systematic review, meta-analysis, and scoping review on lymphatic filariasis in the respective geopolitical zones within the country. The literature used was obtained through online search engines including PubMed and Google Scholar with the heading "lymphatic filariasis in the name of the state", Nigeria. This review revealed an overall prevalence of 11.18% with regional spread of Northwest (1.59%), North Central and North East, (4.52%), South West (1.26%), and South-South with South East (3.81%) prevalence. The disease has been successfully eliminated in Argungu local government areas (LGAs) of Kebbi State, Plateau, and Nasarawa States respectively. Most clinical manifestations (31.12%) include hydrocele, lymphedema, elephantiasis, hernia, and dermatitis. Night blood samples are appropriate for microfilaria investigation. Sustained MDAs, the right testing methods, early treatment of infected cases, and vector control are useful for the elimination of lymphatic filariasis for morbidity management and disability prevention in the country. Regional control strategies, improved quality monitoring of surveys and intervention programs with proper records of morbidity and disability requiring intervention are important approaches for the timely elimination of the disease in Nigeria.

Comparison of Intermittent Pneumatic Compression Pump as Adjunct to Decongestive Lymphatic Therapy against Decongestive Therapy Alone for Upper Limb Lymphedema after Breast Cancer Surgery: A Systematic Review and Meta-Analysis.
BACKGROUND
Breast cancer is among the most prevalent malignancies in women worldwide, with substantial morbidity and mortality. Upper limb lymphedema (ULL) is a common complication after breast cancer surgery that affects patients' daily activities and quality of life. Decongestive lymphatic therapy (DLT) and intermittent pneumatic compression (IPC) therapy are 2 primary treatment methods for ULL.
OBJECTIVES
This study aimed to compare the efficacy of DLT with IPC versus DLT alone in the management of ULL following breast cancer surgery.
METHOD
PubMed Central, SCOPUS, EMBASE, MEDLINE, Cochrane Trial Registry, Google Scholar, and Clinicaltrials.gov databases were comprehensively searched for randomized controlled trials (RCTs) comparing DLT with IPC and DLT alone in patients with breast cancer-related ULL. The risk of bias was evaluated using the RoB 2 tool. Pooled effect sizes were calculated using random-effects models.
RESULTS
A total of 1,894 citations were identified by the systematic search. Of them, 9 RCTs were included in the analysis. The pooled standardized mean difference (SMD) for percentage volume reduction was 0.63 (95% confidence interval [CI]: -0.24 to 1.50; = 90.9%), showing no significant difference between the DLT alone and DLT combined with IPC ( = 0.15). Pain and heaviness scores were also comparable between the groups. However, there was a significant difference in external rotation joint mobility (SMD = 0.62; 95% CI: 0.08-1.16; = 23.8%), favoring DLT with IPC.
CONCLUSIONS
Our findings suggest that DLT with IPC and DLT alone showed similar findings in managing ULL after breast cancer surgery, with DLT with IPC showing a greater impact on external rotation joint mobility. Healthcare providers should consider patient preferences and individual factors when selecting the most appropriate treatment modality for ULL management.

Meta-Analysis Comparative Study
BACKGROUND
Vascularized lymph node transfer (VLNT) involves the microvascular transplantation of functional lymph nodes from a donor site into a limb affected by lymphedema to restore the normal flow of lymphatic fluid. Despite the increasing clinical experience with VLNT, there remains insufficient data to support its routine use in clinical practice. Here, we aim to evaluate the effectiveness and safety of VLNTs for upper limb lymphedema and compare clinical outcomes when using different donor sites.
METHODS
We carried out a systematic search of the literature through PubMed and Scopus databases for studies on VLNT for upper limb lymphedema. Primary and secondary outcomes included circumference reduction rate (CRR) and infection reduction rate by postoperative cellulitis episodes for the efficacy and safety of VLNT. Pooled analysis was performed using the inverse variance weighting meta-analysis of single means using the meta package in R software. Subgroup analyses were performed for donor and recipient sites, age groups, follow-ups, and symptom durations. Quality assessment was performed using the Newcastle-Ottawa Scale for nonrandomized studies.
RESULTS
A total of 1089 studies were retrieved from the literature, and 15 studies with 448 upper limb lymphedema patients who underwent VLNT were included after eligibility assessment. The mean CRR was 34.6 (18.8) and the mean postoperative cellulitis episodes per year was 0.71 (0.7). The pooled analysis of CRR was 28.4% (95% confidence interval, 19.7-41.1) and postoperative cellulitis episodes showed a mean of 0.59 (95% confidence interval, 0.36-0.95) using the random-effect model. Subgroup analyses showed significant group differences in recipient site for CRR and postoperative cellulitis episodes with the wrist comprising the highest weights, and patients younger than 50 years showing a lower postoperative infection.
CONCLUSIONS
Vascularized lymph node transfer using gastroepiploic flaps at the wrists has shown a significant difference in reductions of limb circumference and cellulitis episodes in upper limb lymphedema patients when compared with other donor sites. However, further prospective studies are needed to consolidate this finding.

Review
BACKGROUND
Various surgical treatments are increasingly adopted and gaining popularity for lymphedema treatment. However, challenges persist in selecting appropriate treatment modalities targeted for individual patients and achieving consensus on choice of treatment as well as outcomes. The systematic review aimed to create a treatment algorithm incorporating the latest scientific knowledge, to provide healthcare professionals and patients with a tool for informed decision-making, when selecting between treatments or combining them in a relevant manner. This systematic review evaluated and synthesized the evidence on the effectiveness of three surgical treatments for breast cancer-related lymphedema (BCRL): lymphovenous anastomosis (LVA), vascularized lymph node transfer (VLNT), and liposuction.
METHODS
We conducted a systematic search of electronic databases on 18 June 2023, including Medline, Embase, Cochrane Library, Google Scholar, and ClinicalTrials.org. Eligible studies were randomized controlled trials, non-randomized comparative studies, and observational studies that assessed the outcomes of LVA, VLNT, or liposuction in managing BCRL. The primary results of interest were changes in arm volume, lymphatic flow, and quality of life. Two independent reviewers performed the study selection and data extraction. Following this, we systematically reviewed and conducted a risk of bias assessment. Results were qualitatively presented, and a treatment algorithm was developed based on the available data.
RESULTS
We identified 16,593 papers, after removal of duplicates. Following assessment of studies, 73 articles met the inclusion criteria, including 2,373 patients. We were not able to conduct a meta-analysis due to considerable heterogeneity in the methodologies and outcome measures across the studies. Liposuction appears effective for patients presenting with non-pitting lymphedema. LVA indicates variable success rate, with some evidence indicating a reduction in limb volume and symptomatic relief amongst early stages of lymphedema. VLNT showed promising results for limb volume reduction and symptom improvement in patients presenting with mild and moderate lymphedema.
CONCLUSIONS
Liposuction, LVA, and VLNT seem to be effective treatments for BCRL, when targeted for the appropriate patient. Well-conducted high evidence clinical studies in the field are still lacking to uncover the efficacy of surgical treatment for BCRL.

Clinical Breast Cancer May 2024The objective of this systematic review and meta-analysis was to evaluate the impact of kinesiology taping on individuals suffering from breast cancer-related lymphedema.
PURPOSE
The objective of this systematic review and meta-analysis was to evaluate the impact of kinesiology taping on individuals suffering from breast cancer-related lymphedema.
METHODS AND METHODS
We conducted a comprehensive search in PubMed, Cochrane Library, and Embase databases, spanning from their inception date to December 20, 2023, to identify pertinent studies. Inclusion criteria comprised studies that (1) enrolled participants diagnosed with breast cancer-related lymphedema; (2) implemented kinesiology taping as the intervention; (3) incorporated either complete decongestive therapy, exercise, or sham taping as the control treatment; and (4) included clinical measurements such as the severity of lymphedema, upper limb function assessment, quality of life, and perceived comfort.
RESULTS
Information was extracted from 14 randomized controlled trials (RCTs). The analyses demonstrated statistically significant improvement, indicating a preference for kinesiology taping in the outcomes of upper limb functional assessment (standardized mean difference [SMD] = -0.88, 95% confidence interval [CI]: [-1.22, -0.55]), quality of life (SMD = 0.50, 95% CI: [0.16, 0.84]), and perceived comfort (SMD = 0.85, 95% CI: [0.34, 1.36]).
CONCLUSION
The findings suggest that kinesiology taping could be considered a viable option for individuals dealing with breast cancer-related lymphedema. Nevertheless, acknowledging certain limitations within this study, further confirmation of its benefits necessitates additional larger-scale and better-designed RCTs.

Lymph node metastasis in vulvar cancer is a critical prognostic factor associated with higher recurrence and decreased survival. A survival benefit is reported with adjuvant radiotherapy but with potential significant morbidity. We aim to clarify whether there is high-quality evidence to support the use of adjuvant radiotherapy in this setting. The aim of the study was to assess the effectiveness and safety of adjuvant radiotherapy to locoregional metastatic nodal areas. We conducted a comprehensive and systematic literature search of MEDLINE, Embase, Cochrane Central Register of Controlled Trials, Google Scholar, ClinicalTrials.gov, and the National Cancer Institute. We considered only randomized controlled trials (RCTs). We identified 1,760 records and finally retrieved only one eligible RCT (114 participants with positive inguinofemoral lymph nodes). All women had undergone radical vulvectomy and bilateral inguinal lymphadenectomy and had been randomized to adjuvant radiotherapy or to intraoperative ipsilateral pelvic lymphadenectomy without adjuvant radiotherapy. At 6 years, the overall survival (OS) was 51% versus 41% in favor of radiotherapy (HR 0.61; 95% CI 0.30-1.3) without significance and with very low certainty of evidence. At 6 year, the cumulative incidence of cancer-related deaths was 29% versus 51% in favor of adjuvant radiotherapy (HR 0.49; 95% CI 0.28-0.87). Recurrence-free survival at 6 years was 59% after adjuvant radiotherapy versus 48% after pelvic lymphadenectomy (HR 0.39; 95% CI 0.17-0.88). Three (5.3%) versus 13 (24.1%) groin recurrences were noted, respectively, in the adjuvant radiotherapy and pelvic lymphadenectomy groups. There was no significant difference in acute toxicities for pelvic lymphadenectomy compared to radiotherapy. In women with positive pelvic lymph nodes (20%), the OS at 6 year was 36% compared with 13% in favor of adjuvant radiotherapy. Late cutaneous toxicity rate appeared to be greater after radiotherapy (19% vs. 15%) but with less chronic lymphedema (16% vs. 22%). There is only very low-quality evidence on administering adjuvant radiotherapy for inguinal lymph node metastases. Although the identified study was a multicenter RCT, there was a reasonable imprecision and inconsistency because of small study numbers, wide confidence intervals in the data, and early trial closure, resulting in downgrading of the evidence.

Meta-Analysis Comparative Study
OBJECTIVE
Although several acupuncture and moxibustion therapies have been tested in managing breast cancer-related lymphedema (BCRL), there is little consensus regarding the best options for treating this condition. This systematic review and network meta-analysis compared the efficacy of various acupuncture and/or moxibustion therapies for BCRL.
METHODS
Seven databases and two clinical registration centers were searched from their inception to December 1st, 2023. The Cochrane Collaboration risk-of-bias assessment tool evaluated the quality of included RCTs. A pairwise meta-analysis was performed in STATA 16.0, while a network meta-analysis was performed in R 4.2.2.
RESULTS
18 studies were included in this analysis. Our results showed that acupuncture and moxibustion methods had great advantages in improving BCRL of patients with breast cancer. In particular, needle-warming moxibustion (NWM) could be the optimal acupuncture and moxibustion method for improving clinical effectiveness and reducing the degree of swelling of affected limbs.
CONCLUSION
Our findings suggest that NWM has great potential in treating BCRL. It may reduce arm circumference, lower swelling levels, and improve clinical effectiveness. Nevertheless, more multi-center, high-quality, and large sample RCTs will be needed in the future.

Meta-Analysis
INTRODUCTION
Neglected tropical diseases (NTDs) mainly affect underprivileged populations, potentially resulting in catastrophic health spending (CHS) and impoverishment from out-of-pocket (OOP) costs. This systematic review aimed to summarize the financial hardship caused by NTDs.
METHODS
We searched PubMed, EMBASE, EconLit, OpenGrey, and EBSCO Open Dissertations, for articles reporting financial hardship caused by NTDs from database inception to January 1, 2023. We summarized the study findings and methodological characteristics. Meta-analyses were performed to pool the prevalence of CHS. Heterogeneity was evaluated using the I2 statistic.
RESULTS
Ten out of 1,768 studies were included, assessing CHS (n = 10) and impoverishment (n = 1) among 2,761 patients with six NTDs (Buruli ulcer, chikungunya, dengue, visceral leishmaniasis, leprosy, and lymphatic filariasis). CHS was defined differently across studies. Prevalence of CHS due to OOP costs was relatively low among patients with leprosy (0.0-11.0%), dengue (12.5%), and lymphatic filariasis (0.0-23.0%), and relatively high among patients with Buruli ulcers (45.6%). Prevalence of CHS varied widely among patients with chikungunya (11.9-99.3%) and visceral leishmaniasis (24.6-91.8%). Meta-analysis showed that the pooled prevalence of CHS due to OOP costs of visceral leishmaniasis was 73% (95% CI; 65-80%, n = 2, I2 = 0.00%). Costs of visceral leishmaniasis impoverished 20-26% of the 61 households investigated, depending on the costs captured. The reported costs did not capture the financial burden hidden by the abandonment of seeking healthcare.
CONCLUSION
NTDs lead to a substantial number of households facing financial hardship. However, financial hardship caused by NTDs was not comprehensively evaluated in the literature. To develop evidence-informed strategies to minimize the financial hardship caused by NTDs, studies should evaluate the factors contributing to financial hardship across household characteristics, disease stages, and treatment-seeking behaviors.

BACKGROUND
The effect of first-line complex decongestive therapy (CDT) for breast cancer-related lymphedema (BCRL) depending on various factors forces patients to seek additional treatment. Therefore, this meta-analysis was conducted to evaluate the effect of different conservative medical interventions as a complement to CDT. This is the first meta-analysis that includes various kinds of conservative treatments as adjunctive therapy to get broader knowledge and improve practical application value, which can provide recommendations to further improve BCRL patients' health status.
METHODS
RCTs published before 18 December 2023 from PubMed, Embase, Cochrane Library, and Web of Science databases were searched. RCTs that compared the effects of conservative medical intervention were included. A random-effects or fixed-effects model was used based on the heterogeneity findings. Study quality was evaluated using the Cochrane risk of bias tool.
RESULTS
Sixteen RCTs with 690 participants were included, comparing laser therapy, intermittent pneumatic compression (IPC), extracorporeal shock wave therapy (ESWT), electrotherapy, ultrasound, diet or diet in combination with synbiotic supplement, traditional Chinese medicine (TCM), continuous passive motion (CPM), and negative pressure massage treatment (NMPT). The results revealed that conservative medical intervention as complement to CDT had benefits in improving lymphedema in volume/circumference of the upper extremity [SMD = -0.30, 95% CI = (-0.45, -0.15), < 0.05, 51%], visual analog score (VAS) for pain [SMD = -3.35, 95% CI (-5.37, -1.33), < 0.05, 96%], quality of life [SMD = 0.44, 95% CI (0.19, 0.69), < 0.05, 0], and DASH/QuickDASH [SMD = -0.42, 95% CI (-0.70, -0.14), < 0.05, 10%] compared with the control group. Subgroup analysis revealed that laser therapy and electrotherapy are especially effective ( < 0.05).
CONCLUSION
Combining conservative medical interventions with CDT appears to have a positive effect on certain BCRL symptoms, especially laser therapy and electrotherapy. It showed a better effect on patients under 60 years old, and laser therapy of low to moderate intensity (5-24 mW, 1.5-2 J/cm) and of moderate- to long-term duration (≥36-72 sessions) showed better effects.

Review
PURPOSE
Nutrition plays an important role in cancer survivorship. This systematic review and meta-analysis aim to critically assess and quantify the effectiveness of nutrition care interventions provided by dietitians to survivors who have completed treatment for cancer.
METHODS
A systematic review of randomized controlled trials (RCTs) published from January 2004 to November 2023 reporting the effectiveness of primary care dietetic interventions with adult cancer survivors was conducted. PubMed, Scopus, CINAHL, Embase, ProQuest and PsycINFO databases were searched for key terms. Meta-analyses were conducted where there were sufficient studies of the same cancer type and outcomes.
RESULTS
Twelve RCTs representing 1138 cancer survivors (519 breast cancer; 75 prostate cancer; 544 colorectal cancer) were included. Primary outcome measures included weight loss (n = 6), quality of life (n = 2), reducing lymphedema-related arm volume (n = 2), nutritional status (n = 1) and increasing fruit and vegetable intake (n = 1). Weight loss was observed in studies where this was the primary outcome. Results for quality of life varied. Meta-analyses of RCTs with breast cancer survivors showed that dietitian intervention achieved a mean of 3.7 kg greater intentional weight loss and 2.3% greater body fat decrease than control (p < 0.0001).
CONCLUSIONS
This study provides evidence for the effectiveness of primary care dietetic interventions by dietitians with cancer survivors, particularly with respect to intentional weight and fat loss in breast cancer survivors.
IMPLICATIONS FOR CANCER SURVIVORS
Dietitians can play a key role in managing weight and improving long term health outcomes and prognosis for cancer survivors beyond the acute care setting.
