ABSTRACT

BACKGROUND: Neisseria gonorrhoeae, the causative agent for sexually transmitted infection (STI) gonorrhoea, has emerged with a significant public health impact on acquiring resistance to antimicrobials available for treatment. The resistance of N. gonorrhoeae limit treatment options and contributed to high morbidity associated with gonorrhoea. Data on antimicrobial resistance (AMR) profiles in N. gonorrhoeae is scares in Zambia. This study aimed to determine the antibiotic susceptibilities in N. gonorrhoeae isolates from Lusaka, Zambia.

METHODS: A prospective cross-sectional study was conducted on 630 STI patients who presented with urethral or vaginal discharge from 2019 to 2020. Urethral and endocervical secretions were cultured on Modified Thayer Martin agar and incubated at 36 °C ± 1 °C in 5% CO₂ for 24 h. Identification of N. gonorrhoeae isolates was achieved by Gram stain, oxidase, nitrocefin disk, BactiCard Neisseria, and Viteck® Compact. The AMR profiles were determined using E-test. Statistical significant was determined by Pearson’s Chi-square test, Mann-Whitney U test, or logistic regression with p-values of < 0.05 indicating significance.

RESULTS: A total of 630 patients were recruited of which 46% (290/630) with the median of 29 years and interquartile range (IQR) of 19-39 years were male. The median of the females was 26 years and IQR of 15-37 years. Neisseria gonorrhoeae was isolated from 19.4% (122/630) patients of which 72.9% (89/122) were male, with highest prevalence of isolation in the age category of 25-34 years. The prevalence of resistance was high to penicillin (85.2%), tetracycline (68.9%) and ciprofloxacin (59.8%) with MIC₉₀ of 32 µg/mL, 8 µg/mL, and 8 µg/mL respectively. The isolates had reduced susceptibility to cefixime (1.6%), spectinomycin (4.9%) and (4.9%) for azithromycin. All isolates were susceptible to ceftriaxone. Risk factors associated with AMR were douching in females (AOR 6.69, 95% CI; 1.11-40.31, p = 0.039), female gender (AOR 7.64, 95% CI; 1.11-52.33, p = 0.048), HIV-positivity (AOR 26.59, 95% CI; 3.67-192.7, p = 0.005), no condom use or unprotected sex (AOR 5.48, 95% CI; 1.17-22.75 p = 0.026), sex trading (AOR 4.19, 95% CI; 1.55-11.33, p = 0.010), and over-counter treatment of ciprofloxacin (AOR 3.44, 95% CI; 1.17-22.75, p = 0.023).

CONCLUSION: The N. gonorrhoeae resistance to penicillin, tetracycline and ciprofloxacin was high necessitating revision of the treatment guidelines. However, no resistance to ceftriaxone was detected. Therefore, monitoring of antibiotic resistance remains critical in Zambia.

ABSTRACT

BACKGROUND: Functional recovery is an important treatment goal in major depressive disorder (MDD). This study assessed the real-world effectiveness of vortioxetine in patients with MDD, with particular focus on functioning; dose-response was also assessed.

METHODS: This was a non-interventional, prospective, multicenter study conducted in Greece. Adult outpatients with MDD (n = 336) initiating vortioxetine (5-20 mg/day flexible dosing) as treatment for a current major depressive episode were followed for 3 months. Analyses were stratified according to vortioxetine dosage at 3 months: 5-10 mg/day versus 15-20 mg/day. Functioning was assessed using the Sheehan Disability Scale (SDS).

RESULTS: Mean ± standard error SDS total score decreased (improved) from 18.7 ± 0.3 at baseline to 12.9 ± 0.3 after 1 month of vortioxetine treatment and 7.8 ± 0.4 after 3 months (p < 0.001 vs. baseline for all comparisons). Functional recovery (SDS score ≤ 6) was achieved in 14.6% of patients after 1 month of treatment and 48.4% of patients after 3 months. Improvement from baseline in SDS total and domain scores at 3 months was more pronounced in patients receiving vortioxetine 15-20 mg/day than in those receiving vortioxetine 5-10 mg/day. The mean ± standard error change in SDS total score from baseline was 9.2 ± 0.8 in the 5-10 mg/day group and 12.1 ± 0.4 in the 15-20 mg/day group (p < 0.001). Limitations of this study include its non-interventional study design and lack of a control group or active comparator.

CONCLUSIONS: Statistically significant and clinically relevant improvements in functioning were seen in patients with MDD treated with vortioxetine in a real-world setting. Higher doses of vortioxetine were associated with significantly greater improvements in functioning.

ABSTRACT

BACKGROUND: Globally, the usage of herbal medicines (HMs) is increasingly growing in treating and preventing various ailments. Although, HMs play a vital role in healthcare, concerns have been raised over their safety. Since pharmacy professionals are at the right position to provide patients with evidence-based information on herbals, they should be knowledgeable enough on the subject matter. Thus, the aim of the study was to assess the knowledge, attitude and prevalence of HMs use and its associated factors among pharmacy professionals.

METHOD: An analytical cross-sectional study was conducted among pharmacy professionals working in drug retail outlets in Asmara (the capital city of Eritrea). A census design was employed and data were collected through face-to-face interview. Data were entered and analyzed using Census and Survey Processing System (version-7.2) and IBM Statistical Package for Social Sciences (version 26), respectively. Descriptive and analytical statistics including Mann-Whitney U test/Kruskal-Wallis test and logistic regression were employed. P-values less than 0.05 were considered as significant.

RESULTS: A total of 50 pharmacy professionals (90.9% response rate) were enrolled in the study. Majority of them (62%) were males and two-thirds had a bachelor’s degree. The overall median (Interquartile range, IQR) knowledge score was found to be 24 (12.16) out of 100 with a minimum score of 8 and maximum score of 53. Generally, the median (IQR) attitude score was 70.4 (4.2) out of 100. Majority (78%) of them had used HM for self-treatment. Only religion was found to be a significant determinant of knowledge on indication of HMs (p = 0.015), while attitude score was independent of the potential determining factors. Moreover, prevalence of use was significantly associated with pharmacy ownership (Adjusted Odds Ratio (AOR) =14.44, 95%Confidence Interval (CI): 1.67, 124.52) as well as with the percentage attitude score (AOR = 0.632, 95%CI: 0.41, 0.96) at multivariable level.

CONCLUSION: Generally, the overall knowledge score of pharmacy professionals was low. However, they possessed positive attitude towards herbal medicines. Besides, there was prevalent usage of herbal medicine for self-treatment. This outcome triggers the need for educational courses and workshops centered on herbal medicine.

ABSTRACT

BACKGROUND: The Maslach Burnout Inventory (MBI) is an instrument commonly used to evaluate burnout syndrome. The goal of the present study was to assess the internal reliability and the performance of the items and the subscales of the MBI-HSS (the version for professionals working in human services) by validating its factorial structure in Spanish urgency healthcare personnel.

METHODS: Cross-sectional study including 259 healthcare emergency professionals (physicians and nurses) in the Spanish health region of Lleida and the Pyrenees. Burnout was measured using the Spanish validated version of the MBI-HSS. Internal reliability was estimated using Cronbach’s alpha coefficient. The sampling adequacy was assessed using the Kaiser-Meyer-Olkin measure along with the Bartlett’s test of sphericity. A principal axis exploratory factor analysis with an oblique transformation of the solution and a confirmatory factor analysis with maximum likelihood estimation were performed. Goodness-of-fit was assessed by means of the chi-square ratio by the degrees of freedom, the standardized root mean square residual (SRMR), the root mean square error of approximation (RMSEA), the Tucker-Lewis Index (TLI) and the comparative fit index (CFI).

RESULTS: The three subscales showed good internal reliability with Cronbach’s alpha coefficients exceeding the critical value of 0.7. Exploratory factor analysis revealed five factors with eigenvalues greater than 1. Nevertheless, confirmatory factor analysis showed a relatively satisfactory fit of the three-factor structure (χ²/df = 2.6, SRMR = 0.07, RMSEA = 0.08, TLI = 0.87, CFI = 0.89), which was improved when several items were removed (χ²/df = 1.7, SRMR = 0.04, RMSEA = 0.05, TLI = 0.97, CFI = 0.98).

CONCLUSIONS: Although it is necessary exploring new samples to get to more consistent conclusions, the MBI-HSS is a reliable and factorially valid instrument to evaluate burnout syndrome in health professionals from the Spanish emergency services.

ABSTRACT

BACKGROUND: The present study aimed to assess the impact of application of fluoridated- 10% carbamide peroxide (CP) with or without potassium iodide (KI) on silver diamine fluoride (SDF)-treated enamel surface in the primary teeth.

METHODS: After stained-remineralized caries lesions (s-RCLs) creation, 96 teeth were randomly allocated to four experimental groups: Group 1:SDF-treated enamel followed by 8-h/day application of 10% CP for 2 weeks; Group 2: SDF-treated enamel followed by 15-min/day application of 10% CP for 3 weeks; Group 3: SDF + KI-treated enamel followed by 8-h/day application of 10% CP for 2 weeks; and Group 4: SDF + KI-treated enamel followed by 15-min/day application of 10% CP for 3 weeks. Enamel microhardness (EMH) test (n = 12) and spectrophotometric color assessment (n = 12) was performed at four stages: baseline (intact enamel), demineralized enamel, aged remineralized-stained enamel, and after final intervention. Sixteen samples were used for SEM evaluation. Data were analyzed with the paired t-test, one-way ANOVA, and Tukey’s post-hoc test (p < 0.05).

RESULTS: EMH values in all groups showed significant decrease after demineralization (all, p < 0.00001). All samples showed complete recovery of EMH values (%REMH) after SDF application compared to demineralization (%REMH_SDF) (p = 0.971). Bleaching caused a slight decrease in %REMH for all groups. However, the differences were not statistically significant (p = 0.979). SEM findings revealed no changes in enamel porosity after bleaching. Bleaching application ameliorated the discoloration in all groups (all, p < 0.00001). All samples in Groups 2 and 4 had significantly lighter color after 21 days as compared to 14-day exposure to the bleaching material (both, p < 0.00001).

CONCLUSIONS: SDF application on demineralized primary tooth enamel completely recovered enamel microhardness. 10% carbamide peroxide effectively bleached SDF stain without causing significant decrease in EMH values. Color improvement was more evident with the use of KI immediately after SDF application. Both 15-min and 8-h application of fluoridated CP resulted in statistically similar color enhancement in primary teeth.

ABSTRACT

BACKGROUND: The burden of post-coronavirus disease (COVID)-19 symptoms has been increasing and is of great concern in patients with pre-existing chronic medical conditions.This study aimed to delineate the post-COVID-19 neuropsychiatric symptoms among migraine patients compared to the non-migraine control group.

METHODS: Two groups, each of 204 COVID-19 survivors, were enrolled in the study after 3 months of severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) infection, one group fulfilling the episodic migraine criteria and the other serving as a matching control group. Subjects were evaluated through an in-person interview for post-COVID-19 neuropsychiatric symptoms, including detailed headache patterns and severity, using the visual analogue scale.

RESULTS: The Frequency of headache during the acute phase of COVID-19 was more frequent in migraine patients (OR = 1.60, 95%CI = 1.04-2.45, P-value = 0.031). The reported significant post-COVID-19 neuropsychiatric symptoms in migraine patients compared to controls were fatigue (OR = 1.662, 95%CI = 1.064-2.596, P-value = 0.025), anosmia/hyposmia (OR = 2.06, 95%CI = 1.164- 3.645, P-value = 0.012), cacosmia (OR = 2.663, 95%CI = 1.145-6.195, P-value = 0.019), depression (OR = 2.259, 95%CI = 1.284- 3.975, P-value = 0.004), anxiety (OR = 3.267, 95%CI = 1.747- 6.108, P-value ≤ 0.001), insomnia (OR = 2.203, 95%CI = 1.298- 3.739, P-value = 0.003), and headache (OR = 3.148, 95%CI = 1.616-6.136, P-value = ≤ 0.001).While there was no statistically significant difference between migraine patients and controls regarding the post-COVID-19 functional status score (P-value = 0.102). The pattern of post-COVID-19 headache was reported as chronic headache transformation in 17.6% of the migraine group, with the median intensity rate being 5.5 and IQR (3-7). In the control group, 14% experienced chronic headache attributed to systemic viral infection with a median intensity rate of 2 and IQR (2-5), while 12% experienced a new daily persistent headache with a median intensity of 5 and IQR (1-6).

CONCLUSION: The study highlighted the importance of follow-up migraine patients upon recovery from COVID-19 infection, being more vulnerable to post-COVID-19 symptoms.

ABSTRACT

BACKGROUND: A few studies have reported that maternal administration of antenatal corticosteroids increased the risk of pulmonary edema (PE). However, despite the increasing usage rate of betamethasone as antenatal corticosteroid, maternal administration of betamethasone as a risk factor for PE has not been well studied. This study aimed to evaluate how maternal backgrounds and complications, tocolytic agents, and betamethasone affect the incidence of PE during the perinatal period and determine the risk factor for PE.

METHODS: This was a single-center retrospective cohort study in Kurashiki, Japan. The study subjects were patients who had been admitted to our hospital for perinatal management including pregnancy, delivery and puerperium between 2017 and 2020. The primary outcome measure was defined as the incidence of PE during hospitalization. First, in all study subjects, Cox proportional hazards model was used to determine the risk factor for PE during the perinatal period. Next, using propensity score matching, we divided the patients into the betamethasone and betamethasone-free groups and examined the association between betamethasone use and the incidence of PE with Cox proportional hazards model.

RESULTS: During the study period, 4919 cases were hospitalized, and there were 16 PE cases (0.3%). In all analyzed subjects, the occurrence of PE was significantly associated with preeclampsia (hazard ratio 16.8, 95% confidence intervals (CI) 5.39-52.7, P < 0.001) and the combined use of the tocolytic agents such as ritodrine hydrochloride and magnesium sulfate, and betamethasone (hazard ratio 11.3, 95% CI 2.66-48.1, P = 0.001). In contrast, after propensity score matching, no statistically significant difference was found between the betamethasone and betamethasone-free groups in the incidence of PE (hazard ratio 3.19, 95% CI 0.67-15.3, P = 0.145).

CONCLUSIONS: A combined use of tocolytic agents and antenatal corticosteroids such as betamethasone may be an independent risk factor for PE during the perinatal period. On the other hand, betamethasone use alone may not be associated with the incidence of PE. When tocolytic agents and betamethasone are administrated to pregnant women, it is important to pay attention to the appearance of maternal respiratory symptoms.

ABSTRACT

BACKGROUND: The COVID-19 pandemic and associated public health restrictions temporarily disrupted food supply chains around the world and changed the way people shopped for food, highlighting issues with food systems resilience and sustainability. The aim of this study was to explore consumer-driven strategies towards a more resilient and sustainable food system in Australia, learning from experiences during the beginning of the COVID-19 pandemic.

METHODS: During May-June 2020, a cross-sectional, online survey was conducted in Tasmania, Australia in a non-random sample of adults aged 18 years and over. The survey collected demographic data and posted the open-ended question: “How could Tasmania’s food system be better prepared for a disaster in the future?” Descriptive statistics were used to analyse the demographic data and thematic analysis was employed to analyse the qualitative data.

RESULTS: Survey respondents (n = 698) were predominantly female (79%), over 55 years of age (48%), university educated (70%) and living with dependents (45%). Seven key themes were identified: (i) balance food exports with local needs; (ii) strengthen local food systems; (iii) increase consumer awareness of food supply chains; (iv) build collaboration and connection in the food system; (v) embed clear contingency arrangements; (vi) support community capacity building and individual self-sufficiency; and (vii) the food system coped well.

CONCLUSIONS: The consumer-driven strategies identified indicate multiple opportunities to increase resilience and sustainability in the food system to avoid future supply disruptions. Our findings indicate that considerable popular support for more resilient, local and sustainable food systems may be emerging from the COVID-19 pandemic.

ABSTRACT

BACKGROUND: Quantitative real time PCR (qPCR) is a powerful tool to evaluate mRNA expression level. However, reliable qPCR results require normalization with validated reference gene(s). In this study, we investigated stable reference genes in seven tissues according to four developmental stages in minipigs. Six candidate reference genes and one target gene (ACE2) were selected and qPCR was performed. BestKeeper, geNorm, NormFinder, and delta Ct method through the RefFinder web-based tool were used to evaluate the stability of candidate reference genes. To verify the selected stable genes, relative expression of ACE2 was calculated and compared with each other.

RESULTS: As a result, HPRT1 and 18S genes had lower SD value, while HMBS and GAPDH genes had higher SD value in all samples. Using statistical algorithms, HPRT1 was the most stable gene, followed by 18S, β-actin, B2M, GAPDH, and HMBS. In intestine, all candidate reference genes exhibited similar patterns of ACE2 gene expression over time, whereas in liver, lung, and kidney, gene expression pattern normalized with stable reference genes differed from those normalized with less stable genes. When normalized with the most stable genes, the expression levels of ACE2 in minipigs highly increased in intestine and kidney at PND28, which is consistent with the ACE2 expression pattern in humans.

CONCLUSIONS: We suggest that HPRT1 and 18S are good choices for analyzing all these samples across the seven tissues and four developmental stages. However, this study can be a reference literature for gene expression experiments using minipig because reference gene should be validated and chosen according to experimental conditions.

ABSTRACT

Exome sequencing is becoming a routine in health care, because it increases the chance of pinpointing the genetic cause of an individual patient’s condition and thus making an accurate diagnosis. It is important for facilities providing genetic services to keep track of changes in the technology of exome capture in order to maximize throughput while reducing cost per sample. In this study, we focused on comparing the newly released exome probe set Agilent SureSelect Human All Exon v8 and the previous probe set v7. In preparation for higher throughput of exome sequencing using the DNBSEQ-G400, we evaluated target design, coverage statistics, and variants across these two different exome capture products. Although the target size of the v8 design has not changed much compared to the v7 design (35.24 Mb vs 35.8 Mb), the v8 probe design allows you to call more of SNVs (+ 3.06%) and indels (+ 8.49%) with the same number of raw reads per sample on the common target regions (34.84 Mb). Our results suggest that the new Agilent v8 probe set for exome sequencing yields better data quality than the current Agilent v7 set.
