A systematic review with meta-analysis on the antihypertensive efficacy of Nigerian medicinal plants.

ETHNOPHARMACOLOGICAL RELEVANCE: Despite the promising effects of herbal preparations in lowering blood pressure (BP), hypertension remains a major clinical challenge in Nigeria. The BP-lowering effects of medicinal plants are due to the presence of bioactive compounds. AIM OF THE STUDY: This meta-analysis presents a precise estimate of the therapeutic benefits of medicinal plants utilized in Nigeria for the management of hypertension in animals and humans. METHODS: A systematic literature search was performed through Cochrane, PubMed, Science Direct and Scopus databases from inception until February 28, 2021 using search terms related to randomized controlled trials of Nigerian medicinal plants for hypertension. Additional studies were identified through manual search. BP was the main outcome that was measured after the intervention. Meta-analysis was performed using the Review Manager and Meta-Essential. RESULTS: Nineteen trials comprising of 16 preclinical and 3 clinical studies were enrolled for the meta-analysis. A total number of 16 plants was identified of which H. sabdariffa was the highest reported plant. The plant extracts significantly lowered the systolic blood pressure (SBP) and diastolic blood pressure (DBP) of the hypertensive subjects compared to control. Weighted mean difference (WMD) for SBP (-43.60 mmHg, 95% CI: -63.18, -24.01; p<0.0001) and DBP (-29.50 mmHg, 95 CI: -43.66, -15.34; p<0.0001) was observed for the preclinical studies. For clinical trials, the WMD was -13.98 mmHg, 95 CI: -19.08, -8.88; p<0.00001 for SBP and -10.00 mmHg, 95 CI: -12.22, -7.78; p<0.00001 for DBP. High heterogeneity was observed for the outcome measures of preclinical studies, but not for the clinical studies. The observed substantial heterogeneity in preclinical studies may be linked to methodological shortcomings as evidenced by the results of the risk of bias assessment. There was no evidence of publication bias in animal trials for BP using the funnel plot and Egger's regression test (SBP, p=0.239 and DBP, p=0.112). CONCLUSIONS: This study provides evidence of medicinal preparations for the treatment of hypertension. A well-conducted trial with methodological rigour and a longer duration of follow-up is required for their effective clinical utilization.

Achieving Complete Radiological and Bio-Chemical Response as a Predictor of Long-Term Survival in Stage IV Epithelial Ovarian Cancer.

Objective Epithelial ovarian cancer (EOC) is common among ovarian cancers. The majority of existing literature shows combined data of stage III and stage IV. Therefore, we aimed to look for whether achieving complete radiological and biochemical response after initial treatment of stage IV epithelial ovarian cancer as a predictor of long-term survival in the Pakistani population. Methods A cross-sectional study was conducted of patients with stage IV epithelial ovarian cancer diagnosed and treated from 2006-2013 at Shaukat Khanum Memorial Cancer Hospital and Research Centre, Lahore, Pakistan. Overall survival was defined as the number of months between patients' diagnosis at the hospital and any cause of death or last follow-up date. Kaplan Meier curve was used to report the overall survival. The log-rank test was used to distinguish the survival difference in complete and no complete response. P-value <0.05 was considered statistically significant. Result A total of fifty patients of stage IV epithelial ovarian carcinoma, with a mean age of 53 ± 2 received neoadjuvant chemotherapy and suitable patients underwent interval-debulking surgery. Among these fifty patients, twenty-one (42%) patients who achieved complete radiological and biochemical response had a median survival of greater than five years. Patients without co-morbidities (46%) and having good performance status (52%) showed better results of the treatment. Patients' tolerance to chemotherapy with good response and fit enough to undergo interval-debulking surgery, achieving complete radiological and biochemical response after initial induction therapy were significantly associated with long-term survival (P<0.05). Conclusion Outcomes of patients who present with stage IV EOC remains dismal. Patients who achieved complete radiological and biochemical response after neoadjuvant chemotherapy and interval-debulking surgery was significantly associated with long-term survival.

A review of access to cancer facilities in Punjab, Pakistan.

BACKGROUND: Punjab is the most populous province of Pakistan, with only 12 countries in the world succeeding it in terms of population. AIMS: This review article has the objective of providing novel statistics regarding available cancer therapeutics in Punjab across four different sectors-including government, semi-private, trust and private sectors. METHODS AND RESULTS: Keywords such as "cancer treatment," "facilities," "Pakistan," were used to search Pubmed Database. 36 results were generated: after sifting based on a personal reference list as well as for relevance, 16 articles were finally reviewed. Novel statistics regarding current state of access to cancer facilities were drawn from personal references as well as from studies conducted in other LMICs. There is a gross deficit of oncological services in Punjab, with the ratio of medical oncologists to population being 0.027 per 100, 000, and every oncologist checking 1300-1500 patients annually. Only 21.4% of the population has access to radiotherapy facilities. Major problems include lack of healthcare professional awareness; poor infrastructure including drug access, radiotherapy, and cancer pain management facilities; lack of planning; and lack of educational and research programs. CONCLUSIONS: Improving education & training, developing infrastructure based on public-private-partnership models, building cancer registries and organizing national cancer screening programs, as well as encouraging basic health education and research in oncology, are measures that can ensure Punjab's healthcare delivery system becomes capable of handling increasing incident burden of cancer.
