ABSTRACT

Artemisinin (ART) combination therapy is the main treatment for malaria. Pfk13 mutations (or K13 mutations, Kelch 13) are associated with ART resistance. This study aims to conduct a systematic review and meta-analysis of the prevalence of K13 mutations with ART resistance in malaria-endemic countries. An electronic search of studies in 2018 and a manual search in 2020 were performed to identify relevant studies. The risk of bias was assessed using the National Institutes of Health (NIH) quality assessment tool for observational cohort and cross-sectional studies. Data analysis was performed using R 4.1.0. Heterogeneity was estimated using the statistic I2 and Cochran Q test. A total of 170 studies were included in our review. Of these, 55 studies investigated the prevalence of K13 mutations in Southeast Asia. The meta-analysis showed that Southeast Asia had the highest prevalence of K13 mutations, whereas Africa, South America, Oceania, and other Asian countries outside Southeast Asia had a low prevalence of K13 mutations. The C580Y mutation was the most common in Southeast Asia with 35.5% (95%CI: 25.4-46.4%), whereas the dominant mutation in Africa was K189T (22.8%, 95%CI: 7.6-43.2%). This study revealed the emergence of ART resistance associated with K13 mutations in Southeast Asia. The diversity of each type of K13 mutation in other regions was also reported.

ABSTRACT

The prevalence of common perinatal mental disorders in Vietnam ranges from 16.9% to 39.9%, and substantial treatment gaps have been identified at all levels. This paper explores constraints to the integration of maternal and mental health services at the primary healthcare level and the implications for the health system's responsiveness to the needs and expectations of pregnant women with mental health conditions in Vietnam. As part of the RESPONSE project, a three-phase realist evaluation study, we present Phase 1 findings, which employed systematic and scoping literature reviews and qualitative data collection (focus groups and interviews) with key health system actors in Bac Giang province, Vietnam, to understand the barriers to maternal mental healthcare provision, utilization and integration strategies. A four-level framing of the barriers to integrating perinatal mental health services in Vietnam was used in reporting findings, which comprised individual, sociocultural, organizational and structural levels. At the sociocultural and structural levels, these barriers included cultural beliefs about the holistic notion of physical and mental health, stigma towards mental health, biomedical approach to healthcare services, absence of comprehensive mental health policy and a lack of mental health workforce. At the organizational level, there was an absence of clinical guidelines on the integration of mental health in routine antenatal visits, a shortage of staff and poor health facilities. Finally, at the provider level, a lack of knowledge and training on mental health was identified. The integration of mental health into routine antenatal visits at the primary care level has the potential help to reduce stigma towards mental health and improve health system responsiveness by providing services closer to the local level, offering prompt attention, better choice of services and better communication while ensuring privacy and confidentiality of services. This can improve the demand for mental health services and help reduce the delay of care-seeking.

ABSTRACT

Although the undermining of the nursing profession, time constraints, and the lack of inclusive teaching of evidence-based nursing (EBN) in the nursing school's curriculum have long been identified as being some of the main barriers to the adoption of evidence-based practice (EBP) by nurses, the specific role of nurse leaders in directly influencing and supporting evidence-based nursing is not well demonstrated. This opinion piece discusses potential factors that influence the implementation of EBP into clinical routine practice, as well as how nursing leadership styles can contribute to its promotion in contemporary healthcare settings.

ABSTRACT

BACKGROUND: Meta-analyses are on top of the evidence-based medicine pyramid, yet many of them are not completed after they are begun. Many factors impacting the publication of meta-analysis works have been discussed, and their association with publication likelihood has been investigated. These factors include the type of systematic review, journal metrics, h-index of the corresponding author, country of the corresponding author, funding sources, and duration of publication. In our current review, we aim to investigate these various factors and their impact on the likelihood of publication. A comprehensive review of 397 registered protocols retrieved from five databases was performed to investigate the different factors that might affect the likelihood of publication. These factors include the type of systematic review, journal metrics, h-index of the corresponding author, country of the corresponding author, funding sources, and duration of publication. RESULTS: We found that corresponding authors in developed countries and English-speaking countries had higher likelihoods of publication: 206/320 (p = 0.018) and 158/236 (p = 0.006), respectively. Factors affecting publications are the countries of corresponding author (p = 0.033), whether they are from developed countries (OR: 1.9, 95% CI: 1.2-3.1, p = 0.016), from English-speaking countries (OR: 1.8, 95% CI: 1.2-2.7, p = 0.005), update status of the protocol (OR: 1.6, 95% CI: 1.0-2.6, p = 0.033), and external funding (OR: 1.7, 95% CI: 1.1-2.7, p = 0.025). Multivariable regression retains three variables as significant predictors for the publication of a systematic review: whether it is the corresponding author from developed countries (p = 0.013), update status of the protocol (p = 0.014), and external funding (p = 0.047). CONCLUSION: Being on top of the evidence hierarchy, systematic review and meta-analysis are the keys to informed clinical decision-making. Updating protocol status and external funding are significant influences on their publications. More attentions should be paid to the methodological quality of this type of publication.

ABSTRACT

Diabetes mellitus is a chronic metabolic disease relating to steady hyperglycemia resulting from the impairment of the endocrine and non-endocrine systems. Many new drugs having varied targets were discovered to treat this disease, especially type 2 diabetes. Among those, α-glucosidase inhibitors showed their effects by preventing the digestion of carbohydrates through their inhibition against α-amylase and α-glucosidase. Recently, chalcones have attracted considerable attention as they have a simple structure, are easily synthesized as well as have a variety of derivatives. Some reports suggested that chalcone and its derivates could inhibit α-amylase and α-glucosidase. This narrative review provides a comprehensive evaluation of the inhibition of chalcone and its derivatives against α-amylase and α-glucosidase that were reviewed and reported in published scientific articles. Twenty-eight articles were reviewed after screening 207 articles found in four databases, including PubMed, Google Scholar, VHL (Virtual Health Library), and GHL (Global Health Library). This review presented the inhibitory effects of varied chalcones, including chalcones with a basic structural framework, azachalcones, bis-chalcones, chalcone oximes, coumarin-chalcones, cyclohexane chalcones, dihydrochalcones, and flavanone-coupled chalcones. Many of these chalcones had significant inhibition against α-amylase as well as α-glucosidase that were comparable to or even stronger than standard inhibitors. This suggested that such compounds could be potential candidates for the discovery of new anti-diabetic remedies in the years to come.

ABSTRACT

Panax ginseng is a common natural product, which is well-known to have a wide range of pharmacological activities in cancer. Its metabolite, compound K (CK), has been reported to have anticancer activity. We aimed to systematically review the literature for evidence of anticancer effects of CK. We conducted a systematic search in eight databases. We included all in vitro and in vivo studies investigating the anticancer effects of CK with no restrictions. Quality assessment was applied by ToxRTool. Fifty-four articles were included in our study. The purity of CK in our included studies was at least 95%. The in vitro studies reported that CK had a potential anticancer activity on several cell lines including human lung cancer cell lines (A549, PC-9), nasopharyngeal carcinoma cell line (Hk-1), liver cancer cell line (BEL 7402), and pediatric acute myeloid leukemia cell lines (Kasumi-1, MV4-11). The in vivo studies reported a significant decrease in tumor volume in mice treated with CK. CK is a potential supplementary treatment in cancer chemotherapies. The safety and further clinical trials of CK should be explored for future drug development.

ABSTRACT

Kinesio taping is widely used in musculoskeletal conditions. We performed a systematic review and meta-analysis on the efficacy of kinesio taping in musculoskeletal disorders compared to other interventions. Twelve electronic databases were used for systemic search and data relevant to pain and disability were extracted. The protocol was registered in PROSPERO (CRD42018087606). Meta-analysis was performed to compare the efficacy of kinesio taping to other modalities of musculoskeletal disorders. As a result, 36 studies were included in the quantitative analysis. Kinesio taping was found to provide an improvement of both pain and disability when applied to any region of the body. In the first five days of application, kinesio taping significantly reduced the pain in all body regions (SMD = -0.63, 95%CI: -0.87, -0.39). This was also noted after four-to-six weeks of application (SMD = -0.76, 95%CI: -1.07, -0.45). When kinesio taping was used for disability in low back pain patients, it significantly reduced the disability within five days of application (SMD = -0.70, 95%CI: -1.29, -0.11). Finally, kinesio taping has shown an improvement of the disability in all body regions after four-to-six weeks of application (SMD = -0.59, 95%CI: -0.96, -0.22). Our findings support kinesio taping as an adjuvant to other treatments for musculoskeletal disorders.

ABSTRACT

Background: Uncontrolled blood pressure is a major risk factor for cardiovascular diseases. Fixed-dose combination (FDC) therapy offers a promising approach to addressing this challenge by providing a convenient single-tablet solution that enhances the effectiveness of blood pressure control. In our systematic review, we assess the effectiveness of perindopril/amlodipine FDC in managing blood pressure. Methods: We conducted a comprehensive search across four primary electronic databases, namely, PubMed, Virtual Health Library (VHL), Global Health Library (GHL), and Google Scholar, as of 8 February 2022. Additionally, we performed a manual search to find relevant articles. The quality of the selected articles was evaluated using the Study Quality Assessment Tools (SQAT) checklist from the National Institute of Health and the ROB2 tool from Cochrane. Results: Our systematic review included 17 eligible articles. The findings show that the use of perindopril/amlodipine FDC significantly lowers blood pressure and enhances the quality of blood pressure control. Compared to the comparison group, the perindopril/amlodipine combination tablet resulted in a higher rate of blood pressure response and normalization. Importantly, perindopril/amlodipine FDC contributes to improved patient adherence with minimal side effects. However, studies conducted to date have not provided assessments of the cost-effectiveness of perindopril/amlodipine FDC. Conclusion: In summary, our analysis confirms the effectiveness of perindopril/amlodipine FDC in lowering blood pressure, with combination therapy outperforming monotherapy and placebo. Although mild adverse reactions were observed in a small subset of participants, cost-effectiveness assessments for this treatment remain lacking in the literature.

ABSTRACT

OBJECTIVES: This study aimed to evaluate the efficacy and adverse events of favipiravir in patients with COVID-19. METHODS: Our protocol was registered on PROSPERO (CRD42020206305). Fourteen databases were searched until February 8th, 2021. An update search for new RCTs was done on March 2nd, 2022. Meta-analysis was done for randomized controlled trials (RCTs) and non-RCTs. RESULTS: Overall, 157 studies (24 RCTs, 1 non-RCT, 21 observational studies, 2 case series, and 106 case reports) were included. On hospitalized patients, in comparison to standard of care, favipiravir showed a higher rate of viral clearance at day 5 (RR = 1.60, p = 0.02), defervescence at day 3-4 (RR = 1.99, p <0.01), chest radiological improvement (RR = 1.33, p <0.01), hospital discharge at day 10-11 (RR = 1.19, p <0.01), and shorter clinical improvement time (MD = -1.18, p = 0.05). Regarding adverse events, favipiravir groups had higher rates of hyperuricemia (RR = 9.42, p <0.01), increased alanine aminotransferase (RR = 1.35, p <0.01) but lower rates of nausea (RR = 0.42, p <0.01) and vomiting (R R= 0.19, p=0.02). There were no differences regarding mortality (RR=1.19, p=0.32), and increased aspartate aminotransferase (RR = 1.11, p = 0.25). On nonhospitalized patients, no significant differences were reported. CONCLUSIONS: Adding favipiravir to the standard of care provides better outcomes for hospitalized patients with COVID-19. Pregnant, lactating women, and patients with a history of hyperuricemia should avoid using favipiravir.

ABSTRACT

OBJECTIVE: To overview the colonoscopy adherence in cascade screening of colorectal cancer (CRC) and evaluate potential influence of the initial tests based on an ecological evaluation. METHODS: The performance of the initial screening tests and adherence to subsequent colonoscopy were extracted from relevant studies published up to 16 October 2020. The age-standardised incidence (ASRi) of CRC in populations in the year of screening was derived from the Cancer Statistics. RESULTS: One hundred sixty-six observational studies and 60 experimental studies were identified. Most studies applied cascade screening with faecal occult blood tests (FOBTs) as an initial test. The adherence to colonoscopy varied greatly across populations by continents, gross national income and type of initial tests, with a median (interquartile range) of 79.8% (63.1%-87.8%) in observational studies and 82.1% (66.7%-90.4%) in randomised trials. The adherence was positively correlated with the ASRi of CRC (r = 0.145, p = 0.023) and positive predictive value (PPV) of the initial tests (r = 0.206, p = 0.002) in observational studies and correlated with ASRi of CRC (r = 0.309, p = 0.002) and sensitivity of the initial tests (r = -0.704, p = 0.003) in experimental studies. CONCLUSIONS: Adherence to colonoscopy varies greatly across populations and is related with performance of the initial tests, indicating the importance to select appropriate initial tests.

ABSTRACT

Juvenile granulosa cell tumor (GCT) is a rare ovarian tumor in children, presenting with a multiloculated cystic pattern and irregular wall-thickening on imaging and serous cystadenoma (SCA) is also another rare benign cystic ovarian tumor in children. The appearance of two uncommon types of ovarian tumors on both sides in children is extremely rare. We report the case of a 4-year-old female presenting with symptoms of precocious puberty and diagnosed with juvenile GCT on the left ovary after surgical resection. However, during follow-up 1 year after GCT resection, she presented with another multiloculated cystic mass in the right ovary, and diagnosed as SCA after surgical resection and histopathologic evaluations. The appearance of cystic ovarian tumor after primarily GCT resection need to differentiate between the recurrence of the primarily GCT and other cystic ovarian tumors although it is very uncommon. Furthermore, the imaging features played a key role in the differential diagnosis between benign and malignant ovarian tumors.

ABSTRACT

INTRODUCTION AND IMPORTANCE: Aortic regurgitation and aortic root dilatation are common features in adults with both repaired and unrepaired tetralogy of Fallot (TOF). Valve-sparing aortic root replacement (VSARR) is an effective repair for aortic regurgitation due to progressive aortic root dilatation with TOF after repair. However, the effectiveness of this technique for unrepaired patients has rarely been reported. CASE PRESENTATION: We reported a case of a 30-year-old man with cyanosis and exertional dyspnea. Echocardiography and computed tomography showed unrepaired TOF with significant aortic regurgitation and massively dilated aortic root. Aortic root replacement was mandatory. He underwent successful concomitant VSARR with TOF repair. At 6-month follow-up, he remains stable with trivial aortic regurgitation on echocardiogram. CLINICAL DISCUSSION: In unrepaired TOF, the absence of sub-annular muscular rim and the unbalance of aortic sinuses make VSARR utmost challenging. If can be done successfully, VSARR preserves the native aortic valve and avoids lifelong anticoagulation therapy. CONCLUSION: Concomitant VSARR with TOF repair can be safely and effectively applied for unrepaired patients presenting with progressive aortic root dilatation and significant aortic regurgitation.

ABSTRACT

IL-12 (p35/p40) and IL-23 (p19/p40) signal through IL-12R (IL-12Rß2/ß1) and IL-23R (IL-23Rα/IL-12Rß1), respectively, which can promote pathogenic T lymphocyte activation, differentiation, and function in graft-versus-host disease (GVHD). With the use of murine models of allogeneic hematopoietic cell transplantation (HCT), we found that IL-12Rß1 on donor T cells was dispensable to induce acute GVHD development in certain circumstances, while IL-23Rα was commonly required. This observation challenges the current paradigm regarding IL-12Rß1 as a prerequisite to transmit IL-23 signaling. We hypothesized that p19/EBI3 (IL-39) may have an important role during acute GVHD. With the use of gene transfection and immunoprecipitation approaches, we verified that p19 and EBI3 can form biological heterodimers. We found that IL-39 levels in recipient serum positively correlated with development of acute GVHD in experimental models and in clinical settings, thereby implicating IL-39 in the pathogenesis of acute GVHD. Furthermore, we observed that human T cells can signal in response to IL-39. In chronic GVHD, IL-23Rα and IL-12Rß1 were similarly required for donor T cell pathogenicity, and IL-39 levels were not significantly different from controls without GVHD. Collectively, we identify a novel cytokine, IL-39, as a pathogenic factor in acute GVHD, which represents a novel potential therapeutic target to control GVHD and other inflammatory disorders.

ABSTRACT

BACKGROUND AND OBJECTIVES: It is proposed that severe leucocytosis mainly contributes to pulmonary hypertension by blocking pulmonary capillaries and restricting blood flow. Exchange transfusion (ET) in pertussis has been demonstrated as a safe and useful technique for depleting the leucocyte mass. We aim to discuss four cases of pertussis-induced respiratory distress and the effectiveness of ET in such a setting. MATERIALS AND METHODS: We conducted a retrospective case series at the Infectious Disease Department of Children's Hospital 2 in Ho Chi Minh City, Vietnam, and included four pertussis patients that were confirmed by PCR tests on respiratory secretions, presented with severe leucocytosis and respiratory distress and required mechanical ventilation. RESULTS: Among the included patients, three underwent a double volume ET for leucodepletion, two of whom were discharged after the procedure with proper vitals and laboratory test results. On the other hand, one patient died despite ET, performed late in the course of the disease. Exchange transfusion was not performed in the last patient who died as well. CONCLUSION: Early ET may be a useful and rapid life-saving treatment in children with critical pertussis and severe leucocytosis before cardiopulmonary complications appear.

ABSTRACT

Herbivores control algae and promote coral dominance along coral reefs. However, the majority of previous studies have focused on herbivorous fish. Here we investigated grazing effects of the sea urchin Diadema savignyi on algal abundance and coral recruitment processes. We conducted an in situ cage experiment with three density conditions of D. savignyi (0, 8, 16 indiv. m-2) for three months during the main coral recruitment season in Taiwan. Results demonstrated a strong algal control by D. savignyi. At the end of the experiment, average algal cover was 95% for 0 indiv. m-2, compared to 47% for 8 indiv. m-2 and 16% for 16 indiv. m-2. Average algal biomass at 8 indiv. m-2 declined by one third compared to 0 indiv. m-2 and almost zero at 16 indiv. m-2. On the other hand, a negative grazing effect of D. savignyi was observed on coral recruitment processes. Notably, at 16 indiv. m-2, the density of coral recruits declined and mortality of small coral fragments (proxy of coral juveniles) increased. Our results confirm findings of previous studies and indicate the need to balance both positive (strong algal control) and negative (physical damage) influences of Diadema grazing to facilitate the coral recruitment process.

ABSTRACT

BACKGROUND: Drinking water quality affects directly human health. Assessment and prevention of water-borne diseases are crucial for primary prevention, especially for children. OBJECTIVE: The main aim of this study was to investigate the quality of drinking water from tap water in preschools and primary schools in a district area in Hanoi City, Vietnam. METHODS: A cross-sectional study was performed from August to October 2019. Water samples from tap water of 154 schools in a district area of Hanoi were collected to determine the quality of drinking water. From each school, at least 2 bottles of water samples were collected on the basis of a standard operating procedure (SOP). Each water sample was analyzed for microbial and physicochemical parameters, including Color, Taste and Odor, Turbidity, pH, Nitrite, Nitrate, Ammonium, Total Iron, Permanganate, Chloride, Hardness, Total Manganese, Sulfate, Arsenic, Coliform, and E.coli, by analytical methods. The obtained values of each parameter were compared with the standard values set by WHO and National Technical Regulation on Domestic Water Quality of Vietnam. RESULTS: All of the schools employed community water system as a main source for drinking water. The results showed that all tested samples were found to be within the standards for some physicochemical properties, including Color, Taste and Odor, Hardness, Chloride, Total Iron (Fe2+ và Fe3+), Total Manganese (Mn), Nitrate (NO3 -), Sulfate (SO4 2-), and Total Arsenic (As). On the other hand, some samples did not meet the allowable limits of the national standard, due to pH (3.9%), Turbidity (0.6%), Nitrite (3.2%), Permanganate (6.5%), and Ammonium (5.8%). Furthermore, the microbial data revealed that the substandard water samples from municipal water systems were contaminated by Coliform (9.7%) and/or E.coli (7.8%). CONCLUSIONS AND RECOMMENDATIONS: Contaminants such as bacterial and chemical agents in to drinking water could be occurred during transport, storage and handling before using by the consumer without regular surveillance. A periodic treatment procedure and monitoring system to keep the level of microbial and chemical contamination of drinking water in schools under control should be performed.

ABSTRACT

Isolated bronchial stenosis in infancy is rare, difficult to manage and becomes more complex when associated with congenital heart defects. Given the small luminal diameter and the proximity of the lung parenchyma to the bronchial lesion in infants, reconstruction of the bronchial stenosis is surgically challenging. We present 2 infant cases having isolated critical bronchial obstruction with congenital heart defects, which were successfully managed by primary one-stage slide bronchoplasty with concomitant heart repair. Both cases had excellent results after the surgery and did well at home without requiring respiratory support.

ABSTRACT

Obturator hernia is a rare condition, characterized by the herniation of an intestinal segment between the obturator and the pectineus muscles through the obturator foramen. Obturator hernias usually occur in the elderly and are less common in males than in females, with a male-to-female ratio of about 1/14. In recent years, the use of diagnostic imaging, especially CT, to determine the causes of intestinal obstruction has been improved to allow for an early and accurate diagnosis, even of obturator hernias, which are extremely rare in male patients. We report a thin elderly man, without a history of surgery and with chronic constipation and an unremarkable Howship-Romberg sign, which was correctly diagnosed before surgery as an obturator hernia using CT.

ABSTRACT

A certified reference material, NIMD-01, was developed for the analysis of mercury speciation in human hair. We collected the hair of Vietnamese males from a barbershop in Hanoi in 2016 and prepared 1200 bottles containing 3 g of sieved and blended hair powder. The certified value was given on a dry-mass basis, with the moisture content obtained by drying at 85°C for 4 h. Certified values with the expanded uncertainties (coverage factor, k = 2) were as follows: methylmercury, 0.634 ± 0.071 mg kg-1 as mercury; total mercury, 0.794 ± 0.050 mg kg-1; copper, 12.8 ± 1.4 mg kg-1; zinc, 234 ± 29 mg kg-1; selenium, 1.52 ± 0.29 mg kg-1. An indicative arsenic concentration of 0.17 ± 0.03 mg kg-1 was measured. Extended uncertainties were estimated by sample homogeneity, long- and short-term stabilities, and a characterization from measurements made by collaborating laboratories.
