ABSTRACT

OBJECTIVES: This study aimed to evaluate the diagnostic utility of haematological parameters as a predictive marker of the severity of HIV infection in southwestern Ethiopia.

DESIGN: Comparative cross-sectional study.

SETTING: This study was conducted in southwestern Ethiopia.

PARTICIPANTS: Venous blood samples were collected from 344 participants (172 HIV, 172 healthy controls (HC)) and haematological parameters were determined using the automated haematology analyser. The diagnostic utility of haematological parameters was determined by a receiver operating curve analysis. Data were analysed using SPSS V.21 and the p value was set at less than 0.05 for the statistical significance.

RESULTS: In this study, red cell count (RCC) distinguishes HIV-infected patients from HC at a threshold value of 4.05×10⁹/L with sensitivity, specificity and an area under the curves (AUC) of 73.8%, 78.5% and 0.87, respectively. At a cut-off value of 4.25×10⁹/L, RCC significantly distinguishes non-severe HIV-infected patients from HC with a sensitivity of 72.7%, specificity of 81.7% and an AUC of 0.86. Haemoglobin (Hgb) significantly differentiates severe HIV-infected patients from HC with sensitivity, specificity and an AUC of 95.9%, 86.7% and 0.96, respectively. Platelet count (PLT) significantly discriminates HC from non-severe and severe HIV-infected patients with an AUC of 0.74 and 0.963, respectively.

CONCLUSION: RCC, PLT and Hgb demonstrated better diagnostic performance in predicting the severity of HIV infection and have been identified as the best haematological markers in predicting the presence and severity of HIV infection. Thus, the haematological profiles (RCC, PLT and Hgb) should be used as an alternative marker to predict the severity of HIV infection and may provide supportive information for evidence-based interventions and early diagnosis of infections.

ABSTRACT

BACKGROUND: National lockdowns in England due to COVID-19 resulted in rapid shifts in healthcare provision, including in primary care where most contraceptive prescriptions are issued. This study aimed to investigate contraception prescribing trends in primary care during the pandemic and the impact of socioeconomic deprivation.

METHODS: Prescribing data were accessed from the English Prescribing Dataset for the first year of the COVID-19 pandemic (1 March 2020-28 February 2021) and the year prior (1 March 2019-29 February 2020). Data were analysed by geographical region (London, Midlands and East of England, North of England, South of England) and contraceptive type (progestogen-only pill (POP), combined oral contraception (COC), emergency hormonal contraception (EHC) and contraceptive injections). Differences in prescribing rates were calculated using Poisson regression. Pearson correlation coefficients were calculated for the Index of Multiple Deprivation (IMD) scores for each Clinical Commissioning Group (CCG) in the North East and North Cumbria (NENC).

RESULTS: Contraception prescribing rates decreased overall during the COVID-19 pandemic in England (Poisson regression coefficient (β)=-0.035), with a statistically significant (p<0.01) decrease in all four regions. Prescriptions decreased for COC (β=-0.978), contraceptive injections (β=-0.161) and EHC (β=-0.2005), while POP (β=0.050) prescribing rates increased. There was a weak positive correlation between IMD and prescribing rates in NENC (p>0.05).

CONCLUSIONS: Contraception provision was impacted by COVID-19 with an overall decrease in prescribing rates. The deprivation results suggest that this may not be a significant contributing factor to this decrease. Further research is recommended to better understand these changes, and to ensure that services respond appropriately to population needs.

ABSTRACT

Over time, the metrological concept of uncertainty in measurement has been very successfully integrated into laboratory sciences. For proper implementation, an understanding of specific metrology terminology and additional concepts such as metrology traceability and commutability is necessary. Although the original thinking about measurement uncertainty in laboratory medicine suggests the complexity of the concept, it basically refers to the result as the end product of the entire laboratory process. Although the data on measurement uncertainty can be expressed quantitatively, the basis of this concept is the continuous evaluation of all phases of the laboratory process. This means that laboratory experts should keep in mind that the extra-analytical phases (on which the uncertainty of the measurement results may depend the most) must be continuously monitored. The analytical phase can be “held in check” by established internal and external quality control processes. It is the internal/external quality control data that is used to calculate the numerical value of the measurement uncertainty of the measurement results. Although over time the awareness of laboratory experts regarding the concept of measurement uncertainty has increased, there are still many challenges that need to be followed, and the last one is how to achieve a balance between understanding, evaluation process and application of measurement uncertainty data of measurement results for complete and ultimate practical use.

ABSTRACT

OBJECTIVE: To (1) evaluate changes in student pharmacists’ professional identity during a curriculum prior to advanced pharmacy practice experiences (APPEs) and (2) describe the components of a pre-APPE curriculum that positively and negatively influenced students’ professional identity formation (PIF).

METHODS: The University of Washington School of Pharmacy launched a new curriculum in 2019 featuring components intentionally designed to support students’ PIF. The Macleod-Clark Professional Identity Scale (MCPIS) was administered to the class of 2023 before starting pharmacy school (pre) and upon completion of the pre-APPE curriculum (post). The postsurvey also contained 2 open-response questions asking students to identify the most positive and negative influences on their PIF. Mean pre- and post-responses were calculated for all MCPIS items and each MCPIS item and compared using paired t tests. Responses to the open-ended questions were sorted into categories using inductive thematic analysis and frequencies were calculated.

RESULTS: A total of 99 students (96%) completed both surveys. Mean MCPIS pre-scores and post-scores were both 3.3, indicating no statistically significant change in professional identity. The most frequently reported positive influences on PIF were didactic coursework (40%), experiential learning (30%), and student organizations (27%). The most frequently reported negative influences were didactic coursework (27%), none (25%), and perceptions of the pharmacy profession (22%).

CONCLUSION: Students’ overall professional identity, as measured by the MCPIS, did not change during the pre-APPE curriculum. Didactic coursework had the most common positive and negative influence on professional identity prior to APPEs.

ABSTRACT

OBJECTIVE: The primary objective of this study was to compare grit, subjective happiness, satisfaction with life, and academic resilience among pharmacy and occupational therapy/physical therapy (OT/PT) students at 2 distinct universities using the short grit scale, subjective happiness scale (SHS), satisfaction with life scale (SWLS), and the academic resilience scale (ARS-30).

METHODS: In January 2019, investigators administered an online survey to students at 2 universities using a cross-sectional, voluntary, anonymous survey design using grit scale, SHS, SWLS, and ARS-30. Descriptive statistics, t tests, a 2-way analysis of variance, Pearson correlation, and regression analyses were used to examine the relationship between these scores.

RESULTS: There were 227 respondents who consented to participate in the study and completed all 4 surveys. The overall response rate for pharmacy students was 44% and 43% for OT/PT students, with most pharmacy and OT/PT students in the 19-25-year range. Grit scores did not differ between pharmacy students and OT/PT students, while SHS scores were significantly higher in OT/PT students. Subjective happiness was higher in the private university, with young, female students at the private university reporting higher SHS scores. Although the grit score was not correlated with SWLS, SHS, or ARS-30 scores, the SWLS was correlated with SHS. The SHS was a strong predictor of academic resilience in both OT/PT and pharmacy students.

CONCLUSION: Subjective happiness and satisfaction with life were found to be strong predictors of academic resilience among pharmacy students. Colleges of pharmacy may consider administering the SHS and/or SWLS at baseline and annually to measure well-being.

ABSTRACT

OBJECTIVES: Patients with SLE have higher cardiovascular (CV) risk compared with healthy controls (HC) and are characterised by accelerated atherosclerosis; intima media thickness (IMT), marker of subclinical atherosclerosis, is higher in patients with SLE than in HCs. Retinal microvascular impairment detected through optical coherence tomography angiography (OCTA) was investigated as a marker of systemic vascular involvement in SLE.The aim of the study was to evaluate the relationship between retinal vascular impairment and IMT in SLE.

METHODS: Cross-sectional study recruiting patients with SLE and HCs. Data of the study population were collected. CV risk was evaluated through the American College of Cardiology/American Heart Association (ACC/AHA) guidelines, Framingham and QRESEARCH risk estimator V.3 (QRISK3) scores. Both groups underwent OCTA and carotid ultrasound with IMT assessment.Statistical analysis was accomplished using Pearson/Spearman, t-test/Mann-Whitney or χ² test. Variables statistically significant at univariate regression analysis were tested in an age-corrected and sex-corrected multivariate regression model.

RESULTS: 43 patients with SLE and 34 HCs were recruited. Patients with SLE showed higher triglycerides (p=0.019), Triglycerides-Glucose (TyG) Index (p=0.035), ACC/AHA guidelines (p=0.001), Framingham Risk Scores (p=0.008) and a reduced superficial (p<0.001) and deep (p=0.005) whole retinal vessel density (VD) compared with HCs.In SLE univariate analysis, deep whole VD showed a negative correlation with IMT (p=0.027), age (p=0.001), systolic blood pressure (p=0.011), QRISK3 Score (p<0.001), Systemic Lupus International Collaborating Clinics Damage Index (p=0.006) and apolipoprotein B (p=0.021), while a positive correlation was found with female sex (p=0.029). Age-adjusted and sex-adjusted multivariate analysis confirmed QRISK3 Score (p=0.049) and IMT (p=0.039) to be independent risk factors for reduced retinal VD.

CONCLUSIONS: Patients with SLE showed lower retinal VD and higher CV risk indicators compared with HCs. Among patients with SLE, QRISK3 Score and IMT were found to be independent risk factors for retinal vascular impairment, suggesting a role of OCTA in evaluating preclinical CV involvement in SLE. Moreover, TyG Index could represent a biomarker of CV risk in patients with SLE compared with HCs.

ABSTRACT

BACKGROUND: We aim to assess the impact of montelukast on paediatric patients with asthma/allergic rhinitis, measured using patient-reported outcome measures, compared with other treatments or placebo.

METHODS: Protocol registration CRD42020216098 (www.crd.york.ac.uk/PROSPERO). MEDLINE and Embase databases were used to conduct the search. Two authors independently selected studies and extracted data, and a third reviewer resolved discrepancies. Meta-analyses were constructed to estimate the standardised mean difference (SMD) using a random-effects model.

RESULTS: Out of 3937 articles identified, 49 studies met the inclusion criteria, mostly randomised clinical trials (sample sizes: 21-689 patients). The SMD of change pooled estimators for the global, mental and physical domains of health-related quality of life were not statistically significant. For daytime and night-time symptoms scores, the SMD (95% CI) was in favour of inhaled corticosteroids (-0.12, -0.20- -0.05 and -0.23, -0.41- -0.06, respectively). The pooled estimator for global asthma symptoms was better for montelukast when compared with placebo (0.90, 0.44-1.36).

CONCLUSIONS: The synthesis of the available evidence suggests that, in children and adolescents, montelukast was effective in controlling asthma symptoms when compared with placebo, but inhaled corticosteroids were superior in controlling symptoms, especially at night-time. These findings of our systematic review concur with current guidelines for asthma treatment.

ABSTRACT

BACKGROUND: Chemical-induced allergies at workplace represent a significant occupational health issue. These substances must be properly identified as sensitizers. In previous studies, an original model using mouse bone marrow-derived dendritic cells (BMDC) was developed for this purpose.

OBJECTIVES: The aim of this study was to evaluate the predictive capacity of the BMDC model with a large panel of sensitizers (including pre- and pro-haptens) and non-sensitizers.

METHODS: The readout from the BMDC model is based on expression levels of six phenotypic markers measured by flow cytometry.

RESULTS: The results indicate that 29 of the 37 non-sensitizers, and 81 of the 86 sensitizers were correctly classified compared to the Local Lymph Node Assay (LLNA). Statistical analysis revealed the BMDC model to have a sensitivity of 94%, a specificity of 78%, and an accuracy of 89%. The EC2 (Effective Concentration) values calculated with this model allow sensitizers to be categorized into four classes: extreme, strong, moderate and weak.

CONCLUSIONS: These excellent predictive performances show that the BMDC model discriminates between sensitizers and non-sensitizers with outstanding precision equal to or better than existing validated alternative models. Moreover, this model allows to predict sensitization potency of chemicals. The BMDC test could therefore be proposed as an additional tool to assess the sensitizing potential and potency of chemicals.

ABSTRACT

BACKGROUND: The continued increase in global migration compels clinicians to be aware of specific health problems faced by refugees, immigrants, and migrants (RIM). This analysis aimed to characterize RIM evaluated at GeoSentinel sites, their migration history, and infectious diseases detected through screening and diagnostic workups.

METHODS: A case report form was used to collect data on demographics, migration route, infectious diseases screened, test results, and primary infectious disease diagnosis for RIM patients seen at GeoSentinel sites. Descriptive statistics were performed.

RESULTS: Between October 2016 and November 2018, 5319 RIM patients were evaluated at GeoSentinel sites in 19 countries. Africa was the region of birth for 2436 patients (46 %), followed by the Americas (1,644, 31 %), and Asia (1,098, 21 %). Tuberculosis (TB) was the most common infection screened and reported as positive (853/2,273, 38 % positive by any method). TB, strongyloidiasis, and hepatitis B surface antigen positivity were observed across all migration administrative categories and regions of birth. Chagas disease was reported only among RIM patients from the Americas (393/394, 100 %) and schistosomiasis predominantly in those from Africa (480/510, 94 %). TB infection (694/5,319, 13 %) and Chagas disease (524/5,319, 10 %) were the leading primary infectious disease diagnoses.

CONCLUSIONS: Several infections of long latency (TB, hepatitis B, and strongyloidiasis) with potential for long-term sequelae were seen among RIM patients across all migration administrative categories and regions of origin. Obtaining detailed epidemiologic information from RIM patients is critical to optimize detection of diseases of individual and public health importance, particularly those with long latency periods.

ABSTRACT

OBJECTIVE: To examine the association between depression and the risk of incident irritable bowel syndrome (IBS).

METHODS: We included 98,564 participants free of IBS in the UK biobank. Depression was defined by self-report and Hospital Episode Statistics. The main outcome was incident IBS. Cox proportional hazards regression models and two-sample mendelian randomization were performed to estimate the risk of incident IBS.

RESULTS: Among 98,564 participants, 8770 (8.9 %) participants had a depression diagnosis at baseline. During a median of 12.9-year follow-up, 224 cases of incident IBS were identified in patients with depression (2.0 per 1000 person-years), compared with 1625 cases in reference individuals (1.5 per 1000 person-years). After adjustment, the hazard ratio of incident IBS associated with depression was 1.26 (95 % CI: 1.01-1.41). Sensitivity analysis indicated similar results. The two-sample mendelian randomization based on the inverse variance weighted method provided evidence for the harmful role of depression in an increased risk of IBS with an OR of 1.57 (95 % CI: 1.24-1.99).

LIMITATIONS: Depression was mainly measured by self-report online CIDI-SF in the current study, rather than the gold diagnostic criteria including clinical structured interview, which might lead to potential measurement error. Lifestyle behaviors might change during the long-term follow-up, and time-varying covariates (i.e., smoking and alcohol status) may bias the estimate.

CONCLUSIONS: Depression is associated with an increased risk of incident IBS. Further studies are warranted to confirm the role of depression on incident IBS and elucidate the underlying mechanisms.
