ABSTRACT

OBJECTIVES: To investigate the association between vaccination against Covid-19 and autoimmune rheumatic disease (AIRD) flare.

METHODS: Patients with AIRDs vaccinated against Covid-19 who consulted for disease flare between 01/12/2020 and 31/12/2021 were ascertained in Clinical Practice Research Datalink (Aurum). AIRD flare was defined as consultation for AIRD with corticosteroid prescription on the same day or the next day. Vaccination was defined using date of vaccination and product code. The observation period was partitioned into vaccine-exposed (21-days after vaccination), pre-vaccination (7-days before vaccination), and remaining vaccine-unexposed periods. Participants contributed data with multiple vaccinations and outcomes. Season adjusted incidence rate ratios (aIRR) and 95% confidence intervals (CI) were calculated using self-controlled case-series analysis.

RESULTS: Data for 3554 AIRD cases, 72% female, mean age 65 years, and 68.3% with rheumatoid arthritis were included. Covid-19 vaccination was associated with significantly fewer AIRD flares in the 21-day vaccine-exposed period when all vaccinations were considered (aIRR(95%CI) 0.89(0.80-0.98)). Using dose-stratified analyses there was a statistically significant negative association in 21-days after first Covid-19 vaccination but no association after the second or third Covid-19 vaccinations (aIRR(95%CI) 0.76(0.66-0.89), 0.94(0.79-1.11) and 1.01(0.85-1.20) respectively). On AIRD type stratified analyses, vaccination was not associated with disease flares. Vaccination without or after SARS-CoV-2 infection, and with vectored DNA or mRNA vaccines associated with comparable reduced risk of AIRD flares in the vaccine-exposed period after first Covid-19 vaccination.

CONCLUSION: Vaccination against Covid-19 was not associated with increased AIRD flares regardless of prior Covid-19, AIRD type, and whether mRNA or DNA vaccination technology were used.

ABSTRACT

BACKGROUND: Cervical cancer is an important area of action because of the mortality and morbidity of the disease, and the potential for effective prevention by screening. Involving the social support groups by health education improves cervical cancer screening and early detection of the disease in the community. In the ongoing efforts to strengthen cervical cancer prevention, control, and management, digital health and technology will have a significant role to play.

OBJECTIVE: To assess the effectiveness of the mHealth-based intervention on cervical cancer preparedness among women social support groups.

MATERIALS & METHODS: A pre-post interventional study was conducted among women social support groups from lower socio-economic status, identified from the field practice area. Purposive sampling technique was employed. A Cervical Cancer Awareness Measure (CAM) instrument was used to assess the cancer preparedness among the social support group women After taking inputs from the stakeholders’ mobile health application was developed. The mHealth educational intervention was given to 102 women. Both pre-and post-test questionnaires were administered through mHealth application to assess the change in knowledge after a gap of 1 month to 2 months. The data obtained was coded and entered into Microsoft Excel worksheet 2016 and was later imported and analyzed using SPSS version 22 (licensed to the Institute). The difference in median scores of knowledge and practice were interpreted as statistically significant at p value of < 0.05.

RESULTS & CONCLUSION: Before the intervention only 13 (12.7%) of them had heard about cervical cancer. There was a significant increase in the knowledge about warning signs & symptoms, risk factors of cervical cancer, and HPV vaccination. Around 5% increase in Pap smear test uptake.

ABSTRACT

INTRODUCTION: Spontaneous hemoperitoneum in pregnancy is defined as a sudden non-traumatic intraperitoneal bleeding in pregnancy and up to 42 days postpartum. In the present study we aim to estimate the incidence and investigate the risk factors, the management and the outcomes of spontaneous hemoperitoneum in pregnancy in order to improve its clinical identification and reduce avoidable maternal deaths.

MATERIAL AND METHODS: This is a prospective population-based cohort study, set in maternity units from nine Italian regions covering 75% of the national births. The study population comprises all women admitted for spontaneous intraperitoneal hemorrhage during pregnancy and up to 42 days postpartum between November 2017 and March 2020. Incident cases were reported by trained clinicians through electronic data collection forms. Descriptive statistics were performed. The main outcome measures included incidence rate of spontaneous hemoperitoneum in pregnancy, association with potential risk factors, clinical management and maternal and perinatal outcomes.

RESULTS: Twenty-nine cases met the adopted definition of spontaneous hemoperitoneum in pregnancy with an estimated incidence rate of 0.04 per 1000 births. An increased risk ratio (RR) of this condition was observed in pregnancies conceived by assisted reproductive technology (RR = 6.60, 95% CI 2.52-17.29), in the case of multiple pregnancies (RR = 6.57, 95% CI 1.99-21.69) and maternal age ≥35 years (RR 2.10, 95% CI 1.01-4.35). In 17/29 cases the bleeding site was intra-pelvic (23.5% in the posterior uterine wall and 35.2% in the left hemipelvis). Laparotomy represented the surgical treatment in 27 cases (93%), and most women underwent a cesarean delivery (92.6%). Median blood loss was 1900 mL, one hysterectomy was necessary, and two women died. Twenty-two preterm births were recorded.

CONCLUSIONS: Spontaneous hemoperitoneum in pregnancy is a rare, life-threatening condition associated with high perinatal morbidity and mortality. Maternal age ≥35 years, multiple pregnancies and assisted reproductive technology were associated to a higher risk of the condition. Two women of 29 died and 70% of births occurred preterm.

ABSTRACT

Cumulant mapping employs a statistical reconstruction of the whole by sampling its parts. The theory developed in this work formalises and extends ad hoc methods of ‘multi-fold’ or ‘multi-dimensional’ covariance mapping. Explicit formulae have been derived for the expected values of up to the 6th cumulant and the variance has been calculated for up to the 4th cumulant. A method of extending these formulae to higher cumulants has been described. The formulae take into account reduced fragment detection efficiency and a background from uncorrelated events. Number of samples needed for suppressing the statistical noise to a required level can be estimated using Matlab code included in Supplemental Material. The theory can be used to assess the experimental feasibility of studying molecular fragmentations induced by femtosecond or X-ray free-electron lasers. It is also relevant for extending the conventional mass spectrometry of biomolecules to multiple dimensions.

ABSTRACT

BACKGROUND: There is a high prevalence of concomitant lateral ankle ligament injuries and syndesmotic ligamentous injuries. However, it is unclear whether syndesmotic ligaments directly contribute toward the stability of the lateral ankle. Therefore, the aim of this study was to fluoroscopically evaluate the role of the syndesmotic ligaments in stabilizing the lateral ankle.

METHODS: Twenty-four cadaveric specimens were divided into 3 groups and fluoroscopically evaluated for lateral ankle stability with all syndesmotic and ankle ligaments intact and then following serial differential ligamentous transection. Group 1: (1) anterior talofibular ligament (ATFL), (2) calcaneofibular ligament (CFL), and (3) posterior talofibular ligament (PTFL). Group 2: (1) anterior inferior tibiofibular ligament (AITFL), (2) interosseous ligament (IOL), (3) posterior inferior tibiofibular ligament (PITFL), (4) ATFL, (5) CFL, and (6) PTFL. Group 3: (1) AITFL, (2) ATFL, (3) CFL, (4) IOL, (5) PTFL, and (6) PITFL. At each transection state, 3 loading conditions were used: (1) anterior drawer test performed using 50 and 80 N of direct force, (2) talar tilt <1.7 Nm torque, and (2) lateral clear space (LCS) <1.7 Nm torque. These measurements were in turn compared with those of the stressed intact ligamentous state. Wilcoxon rank-sum test was used to compare the findings of each ligamentous transection state to the intact state. A P value <.05 was considered statistically significant.

RESULTS: The lateral ankle remained stable after transection of all syndesmotic ligaments (AITFL, IOL, PITFL). However, after additional transection of the ATFL, the lateral ankle became unstable in varus and anterior drawer testing conditions (P values ranging from .036 to .012). Lateral ankle instability was also observed after transection of the ATFL and AITFL in varus and anterior drawer testing conditions (P values ranging from .036 to .012). Subsequent transection of the CFL and PTFL worsened the lateral ankle instability.

CONCLUSION: Our findings suggest that isolated syndesmosis disruption does not result in lateral ankle instability. However, the lateral ankle became unstable when the syndesmosis was injured along with ATFL disruption.

CLINICAL RELEVANCE: When combined with ATFL release, disruption of the syndesmosis appeared to destabilize the lateral ankle.

ABSTRACT

BACKGROUND: Despite US naloxone access laws, community pharmacists lack training and confidence in providing naloxone.

OBJECTIVE: To assess the impact of the Empowering Community Pharmacists program on pharmacists’ knowledge, perceived barriers, attitudes, confidence, and intentions regarding naloxone services implementation, as well as naloxone prescriptions dispensed.

METHODS: A 3-month pragmatic randomized controlled trial was conducted from December 2018 to March 2019. Alabama community pharmacists were recruited by mail, email, phone, and fax and randomized to intervention (monthly resources/reminders + educational webinar) or control (monthly reminders only). Outcome measures were assessed via online surveys at baseline (T1), immediately post-intervention (T2), and 3 months post-intervention (T3), including naloxone knowledge (%correct); perceived barriers, attitudes, confidence, and intention regarding naloxone services implementation (7-point Likert-type scale; 1 = strongly disagree, 7 = strongly agree); and number of naloxone prescriptions dispensed. Mean differences between control and intervention from T1 to T3 were assessed using 2-way mixed analysis of variance and adjusted analyses were conducted using generalized estimating equations with negative binomial distribution to assess associations between variables.

RESULTS: Of 55 participants (n = 27 intervention, n = 28 control), most were female (80.3%), white (80.6%), in independently owned pharmacies (39.1%). Increases in mean [SD] confidence (5.52 [1.03]-6.16 [0.74], P < 0.0005) and intention (5.35 [1.51]-6.10 [0.96], P = 0.023) occurred from pre- to post-program within the intervention group and were statistically significant compared with control (confidence P = 0.016, intention P = 0.014). Confidence (exp(β) = 1.46, P = 0.031) and perceived barriers (exp(β) = 0.75, P = 0.022) were associated with number of naloxone prescriptions dispensed.

CONCLUSION AND RELEVANCE: The Empowering Community Pharmacists program improved community pharmacists’ confidence and intention regarding naloxone services implementation. Other states can adapt program elements according to their laws.

ABSTRACT

OBJECTIVE: We reviewed our center’s experience with neonatal and infant hypoplastic aortic arch, unassociated with intracardiac malformations, and investigated changes in prenatal detection rates over time for those requiring therapeutic procedures.

METHODS: We identified all prenatal diagnoses of hypoplastic aortic arch with situs solitus, unassociated with intracardiac malformations, made in Nevada between May 2017 and April 2022. In addition, we identified all those 0-180 days old, with prenatal care, that underwent a surgical or interventional cardiac catheterization aortic arch procedure, whether prenatally or postnatally diagnosed. We excluded those with ventricular septal defects, functionally univentricular hearts, interrupted aortic arches, or any associated malformation requiring an additional surgical or interventional procedure ≤6 months old. Additionally, we calculated prenatal detection rates for those undergoing a surgical or interventional catheterization procedure for each of the 5 years.

RESULTS: We identified 107 patients prenatally and postnatally. Of the 107 patients, 56 (34 prenatally diagnosed and 22 postnatally diagnosed) underwent an aortic arch procedure, and 51 additionally prenatally diagnosed, live-born infants did not undergo a procedure. Of the 56 procedures, 2 were by interventional catheterization, and 54 underwent a surgical repair. Prenatal detection for those undergoing a procedure statistically significantly increased over the 5 years from 38% to 82%, rho = 0.95 (p = .04).

CONCLUSIONS: Currently in Nevada, our prenatal detection rate is >80% in the general population for those between 0 and 6 months old who require a therapeutic procedure for aortic arch obstruction without intracardiac malformations.

ABSTRACT

&lt;br&gt;&lt;b&gt;Aim:&lt;/b&gt; The aim of this study is to evaluate the prevalence of acute cholecystitis (AC) and review its possible management options during the COVID-19 pandemic.&lt;/br&gt; &lt;br&gt;&lt;b&gt;Methods:&lt;/b&gt; The present systematic review and meta-analysis was done in accordance with the PRISMA guideline. In August 2021, two independent reviewers reviewed a number of articles with the aim of finding studies on the management of acute cholecystitis during the COVID-19 pandemic. Articles were searched in the Cochrane, Embassies, and Medline libraries. Using the Stata statistical software 14, the estimated pooled rates were calculated. Funnel plot and I2 indices were applied for evaluating the heterogeneity between the studies.&lt;/br&gt; &lt;br&gt;&lt;b&gt;Results:&lt;/b&gt; An overall of 8 studies consisting of 654 patients suspected for AC were included. The prevalence of COVID-19 among our included patients was 82% (95% CI: 79-84%, I2: 99.2%). Regarding the type of management, 35% (95% CI: 26-45%, I2: 46.9%) of patients undergone cholecystectomy, 47% (95% CI: 43-51%, I2: 54.4%) were managed by non-surgical methods, and 19% (95% CI: 14-23%, I2: 68.1%) of patients were treated by percutaneous cholecystostomy. The prevalence of grade 2 and 3 among our patients was 44 and 15%, respectively.&lt;/br&gt; &lt;br&gt;&lt;b&gt;Conclusions:&lt;/b&gt; Considering the fact that due to the current pandemic, the number of patients referring with higher grades is assumed to be increased, early cholecystectomy remains the best management option for AC patients. However, LC seems not to be the most favorable option since it is associated with a relatively higher risk of contamination with COVID-19. PC can also be considered as a temporary and safe method in high-risk patients which might enable us to protect both patients and healthcare providers.&lt;/br&gt.

ABSTRACT

Equitable allocation of resources targeting the human immunodeficiency virus (HIV) at the local level requires focusing interventions in areas of the greatest need. Understanding the geographical variation in the HIV epidemic and uptake of selected HIV prevention and treatment programmes are necessary to identify such areas. Individual-level HIV data were obtained from a 2012 national HIV survey in South Africa. Spatial regression models on each outcome measure (HIV infection, sub-optimal condom use or non-anti-retroviral treatment (ART) adjusted for spatial random effects at the ward level were fitted using WINBUGS software. In addition, ward-level data was utilized to estimate condom use coverage and ART initiation rates which were obtained from routinely collected data in 2012. Ordinary Kriging was used to produce smoothed maps of HIV infection, condom use coverage and ART initiation rates. HIV infection was associated with individuals undertaking tertiary education [posterior odds ratio (POR): 19.53; 95% credible intervals (CrI): 3.22- 84.93]. Sub-optimal condom use increased with age (POR: 1.09; 95%CrI: 1.06-1.11) and was associated with being married (POR: 4.14; 95%CrI: 1.23-4.28). Non-ART use was associated with being married (POR: 6.79; 95%CrI: 1.43-22.43). There were clusters with high HIV infection, sub-optimal condom use, and non- ART use in Ekurhuleni, an urban and semi-urban district in Gauteng province, South Africa. Findings show the need for expanding condom programmes and/or strengthening other HIV prevention programmes such as pre-exposure prophylaxis and encouraging sustained engagement in HIV care and treatment in the identified areas with the greatest need in Ekurhuleni Metropolitan Municipality.

ABSTRACT

Linkage analysis maps genetic loci for a heritable trait by identifying genomic regions with excess relatedness among individuals with similar trait values. Analysis may be conducted on related individuals from families, or on samples of unrelated individuals from a population. For allelically heterogeneous traits, population-based linkage analysis can be more powerful than genotypic-association analysis. Here, we focus on linkage analysis in a population sample, but use sequences rather than individuals as our unit of observation. Earlier investigations of sequence-based linkage mapping relied on known sequence relatedness, whereas we infer relatedness from the sequence data. We propose two ways to associate similarity in relatedness of sequences with similarity in their trait values and compare the resulting linkage methods to two genotypic-association methods. We also introduce a procedure to label case sequences as potential carriers or noncarriers of causal variants after an association has been found. This post hoc labeling of case sequences is based on inferred relatedness to other case sequences. Our simulation results indicate that methods based on sequence relatedness improve localization and perform as well as genotypic-association methods for detecting rare causal variants. Sequence-based linkage analysis therefore has potential to fine-map allelically heterogeneous disease traits.
