Specific human leucocyte antigen-DQ risk epitope mismatches are associated with chronic lung allograft dysfunction after lung transplantation.

A high-risk epitope mismatch (REM) (found in DQA1∗05 + DQB1∗02/DQB1∗03:01) is associated with de novo donor specific antibodies after lung transplantation (LTx). Chronic lung allograft dysfunction (CLAD) remains a barrier to LTx survival. This study aimed to measure the association between DQ REM and the risk of CLAD and death after LTx. A retrospective analysis of LTx recipients at a single center was conducted between January 2014 and April 2019. Molecular typing at human leucocyte antigen-DQA/DQB identified DQ REM. Multivariable competing risk and Cox regression models were used to measure the association between DQ REM, time-to-CLAD, and time-to-death. DQ REM was detected in 96/268 (35.8%), and DQ REM de novo donor specific antibodies were detected in 34/96 (35.4%). CLAD occurred in 78 (29.1%), and 98 (36.6%) recipients died during follow-up. When analyzed as a baseline predictor, DQ REM status was associated with CLAD (subdistribution hazard ratio (SHR), 2.19; 95% confidence interval [CI], 1.40-3.43; P = .001). After adjustment for time-dependent variables, DQ REM dn-DSA (SHR, 2.43; 95% CI, 1.10-5.38; P = .029) and A-grade rejection score (SHR, 1.22; 95% CI, 1.11-1.35; P = <.001), DQ REM status was not independently associated with CLAD. DQ REM was not associated with death (hazard ratio, 1.18; 95% CI, 0.72-1.93; P = .51). Classification of DQ REM may identify patients at risk of poor outcomes and should be incorporated into clinical decision-making.

Utility of unidimensional and functional pain assessment tools in adult postoperative patients: a systematic review.

BACKGROUND: We aimed to appraise the evidence relating to the measurement properties of unidimensional tools to quantify pain after surgery. Furthermore, we wished to identify the tools used to assess interference of pain with functional recovery. METHODS: Four electronic sources (MEDLINE, Embase, CINAHL, PsycINFO) were searched in August 2020. Two reviewers independently screened articles and assessed risk of bias using the COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN) checklist. RESULTS: Thirty-one studies with a total of 12 498 participants were included. Most of the studies failed to meet the methodological quality standards required by COSMIN. Studies of unidimensional assessment tools were underpinned by low-quality evidence for reliability (five studies), and responsiveness (seven studies). Convergent validity was the most studied property (13 studies) with moderate to high correlation ranging from 0.5 to 0.9 between unidimensional tools. Interpretability results were available only for the visual analogue scale (seven studies) and numerical rating scale (four studies). Studies on functional assessment tools were scarce; only one study included an 'Objective Pain Score,' a tool assessing pain interference with respiratory function, and it had low-quality for convergent validity. CONCLUSIONS: This systematic review challenges the validity and reliability of unidimensional tools in adult patients after surgery. We found no evidence that any one unidimensional tool has superior measurement properties in assessing postoperative pain. In addition, because promoting function is a crucial perioperative goal, psychometric validation studies of functional pain assessment tools are needed to improve pain assessment and management.

Hydroxyurea- a cost effective treatment in developing countries for Atypical Chronic Myeloid Leukemia (aCML): Case Report of Two Patients.

INTRODUCTION: Atypical chronic myeloid leukaemia (aCML) is a rare chronic myeloproliferative disorder with a poor prognosis. CASE REPORT: This case report presents two cases of male geriatric patients, both referred from primary care in rural areas and received at an urban clinic in a tertiary care hospital on separate instances. The first patient complained of low-grade fever (on/off), generalized body aches, rapid weight loss and shortness of breath for the last 2 months. The second patient arrived pale looking with symptoms of generalized body aches, dizziness and anorexia. Both patients were diagnosed to have aCML according to the World Health organization criteria. MANAGEMENT & OUTCOME: Both the patients were from a low economic bracket and were treated with Hydroxyurea a relatively economic medicine successfully. The follow-up lasted for 12 months in both cases. No progression to acute myeloid leukaemia (AML) or relapse was observed. DISCUSSION: This case report shows the promising results of Hydroxyurea in treating aCML and can be a cost effective alternate to other expensive treatments (allogeneic hematopoietic stem cell transplantation) and expensive medicines in lower and middle-income countries especially for resource-limited patients. These two cases show promising evidence for further studies to evaluate and conduct pharmaco-economic evaluations as well as clinical trials to compare hydroxyurea with other available alternative treatments for an affordable therapeutic option towards prevention of relapse and disease free survival after aCML.

Long-Term Potentiodynamic Testing and Tribometric Properties of Amorphous Alloy Coatings under Saline Environment.

Protective coatings for harsh environments are always welcome, but they must overcome profound challenges, including corrosion and wear resistance. The purpose of this study is to look into the long-term potentiodynamic polarization measurements and dry tribometric behavior of plasma-sprayed amorphous coatings on AISI 1035 mild steel. To investigate the impact of unique active polarization potentials on the electrochemical studies of the iron-based amorphous layer, which compares favorably to AISI 1035 mild steel, the active potential polarization curve and friction coefficient tests were performed. Scanning electron microscopy (SEM) and energy dispersive x-ray (EDX) analyses were used to investigate the coating's corrosion behavior. Their mechanical (Tribometric tests at higher sliding speeds) and chemical properties (electrochemical potentiodynamic polarization investigations) have also been thoroughly investigated. There is enough validation that these protective coatings can be used in hostile environments. The effects of long-term corrosion for 24 and 48 h were thoroughly examined. Tribometric examinations revealed that amorphous layers are highly resistant under dry conditions, as they offered a very low and stable friction coefficient less than 4 µ with micro Vickers hardness 1140 ± 22.14 HV, which is more than twice as compared to mild steel AISI 1035. The corrosion resistance of coatings in 3.5 wt % NaCl solution displays active transition characteristics of activation, passivation, over passivation, and pitting, as shown by the potentiodynamic polarization curves.

Comparative genomic analysis of human GLI2 locus using slowly evolving fish revealed the ancestral gnathostome set of early developmental enhancers.

BACKGROUND: The zinc finger-containing transcription factor Gli2, is a key mediator of Hedgehog (Hh) signaling and participates in embryonic patterning of various organs including the central nervous system (CNS) and limbs. Abnormal expression of Gli2 can impede the transcription of Hh target genes through disruption of proper balance between Gli2 and Gli3 functions. Therefore, delineation of enhancers that are required for complementary roles of Glis would allow the interrogation of those pathogenic variants that cause gene dysregulation, and a corresponding abnormal phenotype. Previously, we reported tissue-specific enhancers for Gli family including Gli2 through direct tetrapod-teleost comparisons. RESULTS: Here, we employed the sequence alignments of slowly evolving spotted gar and elephant shark and have identified six novel conserved noncoding elements in human GLI2 containing locus. Zebrafish-based transgenic assays revealed that combined action of these autonomous CNEs reflects many aspects of Gli2 specific endogenous transcriptional activity, including CNS and pectoral fins. CONCLUSION: Taken together with our previous findings, this study suggests that Hh-signaling controlled deployment of Gli2 activity in embryonic patterning arose in the common ancestor of gnathostomes. These GLI2 specific cis-regulatory modules will help to identify DNA variants that probably reside outside of coding intervals and are associated with congenital anomalies.

Attitudes and Associated Demographic Factors Contributing towards the Abuse of Illicit Drugs: A Cross-Sectional Study from Health Care Students in Saudi Arabia.

Background and objective: The purpose of this study is to compare the attitudes, views, and factors that influence drug abuse among pharmacy and nursing students at a Saudi Arabian university. Materials and Methods: A cross-sectional study, was conducted among pharmacy and nursing students who are currently enrolled in the respective courses at the study site. The data were collected over 4 months from August to November 2019 using structured self-administered paper-based questionnaires. Results: Among the participants, pharmacy students accounted for 184 (58.2%) while 132 (41.8%) of the students were from nursing. More than a third of the students 129, (40.8%) smoked cigarettes. The majority of pharmacy (80.4%) and nursing students (67.4%) reported having undertaken a drug misuse course in college. Among the participants, 132 (41.7%) stated that an offer from friends, followed by joy seeking 129 (40.8%), parents' divorce 126 (39.8%), having access to drugs 125 (39.5%), family issues 110 (34.8%), 66 (20.8%) having a family member who is addicted, and 101 (31.9%) reported curiosity to be the factors regarding the use of abusive drugs. Transient euphoria (75.9%) followed by depression 197 (62.3%) was the most prevalent physical or psychological change that occurred following drug use. The family size and father's education have significantly affected the attitudes scores of the students (F = 5.188; p = 0.0001). Conclusion: In this study, joy-seeking, access to drugs, and family issues were found to be the major factors listed as reasons for drug abuse, with some of them being controllable or reversible. Educating about the adverse outcomes of abused drugs is warranted.

Prevalence of potential drug-drug interactions in breast cancer patients and determination of their risk factors.

Breast cancer patients use numerous medications, which include cytotoxic chemotherapy drugs, hormonal agents and supportive medication, so they are more vulnerable to potential adverse drug interactions. This study aimed to evaluate frequency, severity, clinical importance and risk factors responsible for the Drug-drug interactions (DDIs) in a cohort of patients suffering from breast cancer. Data was obtained from 150 patients in the oncology ward (both inpatient and outpatient) with a confirmed diagnosis of breast cancer and currently receiving standard breast cancer-directed treatment. The data was recorded into a pre-designed form specifically made for this study through individual patient interviews and by reviewing the detailed medical chart records of the patients. DDIs were identified by using drug interaction software such as Medscape mobile application and Micromedex version 2.The results of this study showed that all patients were female. The mean numbers of drugs that patients used were 7. Potential drug interactions were identified in 92% of the patients. When drug groups were overviewed, 32% of interactions were between anti neoplastic drugs, 62.9% interactions were between the anti neoplastic agent and supportive care drugs and 5% of them were between anti-cancer drugs and drugs used to treat comorbidities. Major DDIs were found in 62.2% of patients, 25.3% of DDIs were moderate and 12.4% were minor. The number of drugs, comorbid diseases, and selection of chemo protocols were the risk factors for drug interactions. Most of the DDIs found in breast cancer therapy may have adverse consequences on patient health and therapeutic outcomes. Therefore, health care professionals should review the medication regimen of patients with breast cancer before starting any chemotherapy treatment.

Thyroid cancer risk factors and Pakistani University students' awareness towards its preventive practice.

OBJECTIVES: Thyroid Cancer is one of the rarest cancers but its prevalence has been increasing worldwide for the last couple of decades. METHODS: The data collection tool was designed to assess knowledge, awareness, perception, and attitude towards preventive practices of thyroid cancer in Pakistani university students. The data were collected over a duration of six months and a total number of 3722 students participated. RESULTS: The knowledge of risk factors of thyroid cancer was an important parameter of this study. The students who knew all the early signs of thyroid cancer were 28.7%. In this study, the independent variables such as age, gender, demographic location, and financial status were found to be highly significant with knowledge, attitude towards warning signs of cancer, and the perception of students about developing thyroid cancer. CONCLUSIONS: The participants were found to have poor knowledge about early signs of thyroid cancer. The study participants perception, behavior, and attitude towards preventive practices of thyroid cancer were found inadequate and appropriate measures on a National level should be taken to enhance the knowledge about preventive practices of thyroid cancer. Increasing knowledge and awareness shall help decrease the overall morbidity and mortality linked with thyroid carcinomas and thyroid diseases.

Food-based social comparisons influence liking and consumption.

This study examined the effects of food-based social comparisons on hedonic ratings and consumption of a meal. Participants were randomly assigned to one of three experimental conditions in which they were led to believe that they got a worse meal, a better meal, or the same meal as another participant. They then tasted and rated their own meal. Subsequent liking and ad lib food consumption were measured. Participants who were told that another person got a better meal than they did (upward comparison) liked their meal less than if they were told that another person received either the same meal as they did or a worse meal (downward comparison). Similarly, participants who were in the upward comparison condition ate less food than if they were in the control or downward comparison conditions. Consumption was mediated by liking. The results suggest that being told that someone else is eating a meal that is higher or lower in hedonic value than one's own meal induces hedonic contrast and influences liking and consumption.

Profiling of hydroxyurea-treated ß-thalassemia/ serum proteome through nano-LC-ESI-MS/ MS in combination with microsol-isoelectric focusing.

Advancements in proteomic tools offer a comprehensive solution to studying the complexity of diseases at molecular level. This study focusses on the clinical proteomic profiling of pre- and post-hydroxyurea (HU)-treated ß-thalassemia patients in parallel with healthy individuals to better understand the role of HU in the treatment of ß-thalassemia. The strategy encompasses sequential high-resolution protein fractionation using MicroSol-isoelectric focusing (ZOOM- IEF) followed by one-dimensional SDS-PAGE before nano-RP-LC-MS/ MS analysis of tryptic peptides. Protein identification was performed through Mascot search using NCBInr and SwissProt databases. Several different proteins were observed in pool serum samples of each of the three study groups. Approximately, 1250 proteins exclusive to each group were identified, and after removing the redundant and low sequence coverage proteins, the number was reduced to 576 (201 in healthy, 187 in HU-untreated and 188 in HU-treated group). Uniquely identified proteins in the HU-treated group regulate the focal adhesion, ECM-receptor interaction, PI3K-Akt signaling, Rap1 signaling, cAMP signaling, platelet activation, and Ca2+ signaling pathways in the HU-treated group. The proteomic profile presented here will add to the current state of understanding of molecular mechanisms involved in hydroxyurea treatment of ß-thalassemia.

A Cluster of Cefepime-induced Neutropenia During Outpatient Parenteral Antimicrobial Therapy.

A cluster of cefepime-induced neutropenia (CIN) was identified from June 2017 to May 2018 in a regional outpatient parenteral antimicrobial therapy population. Our data suggest prolonged courses of cefepime (≥2 weeks), administered by rapid intravenous push, were associated with a higher risk of CIN.

Untargeted metabolomic analysis of coronary artery disease patients with diastolic dysfunction show disturbed oxidative pathway.

INTRODUCTION: Left ventricular diastolic dysfunction (LVDD) is common in patients with coronary artery disease (CAD) with prevalence estimates of 34% and constitutes a predictor of all-cause mortality. Although diastolic dysfunction is induced by myocardial ischemia and has been shown to alter the clinical course, the role of coronary artery disease in the diastolic dysfunction and its progression into heart failure has not been completely elucidated. OBJECTIVE: The present study was conducted to identify possible metabolites in coronary artery disease patients that are differentially regulated in patients with diastolic dysfunction. METHODS: The serum of CAD (n = 75) patients and young healthy volunteers (n = 43) were analysed by using gas chromatography mass spectrometry (GC-MS) technique. Pre-processing of data results in 1547 features; among them 1064 features were annotated using NIST library. RESULTS AND CONCLUSION: Fifteen metabolites were found to be statistically different between cases and control. Variation in metabolites were identified and correlated with several clinically important echocardiography parameters i.e. LVDD grades, ejection fraction (EF) and E/e' values. The results suggested that metabolic products of fatty acid oxidation and glucose oxidation pathways such as oleic acid, stearic acid, palmitic acid, linoleic acid, galactose, pyruvic and lactic acids are predominantly up regulated in patients with coronary artery disease and severity of diastolic dysfunction appears to be linked to increase in fatty acid oxidation and inflammation. The metabolic fingerprints of these patients give us an insight into the pathophysiological mechanism of diastolic dysfunction in coronary artery disease patients although it did not identify validated novel markers.

Impact of hydroxyurea therapy on serum fatty acids of ß-thalassemia patients.

INTRODUCTION AND OBJECTIVE: Fatty acids (FAs) influence cell and tissue metabolism, function, responsiveness to hormonal and other signals in addition to maintenance of membrane integrity of cells. ß-Thalassemia is a prevalent inherited blood disorder characterized by abnormal red cell membrane structure and function. Induction of HbF by hydroxyurea (HU) is an enduring therapeutic intervention to manage this. Therefore, in the present study we have carried out the quantification of thirteen free fatty acids to disclose the prognosis of HU in ß-thalassemia. METHODS: FAs quantification was carried out using GC-MRM-MS method in the serum of 98 cases of ß-thalassemia patients and out of which samples from 34 patients were collected before and after treatment with HU in addition to healthy controls (n = 31). RESULTS: Using the combination of random forest (RF) with GC-MRM-MS we were able to establish a classification and prediction model that can discriminate the ß-thalassemia from healthy as well as from HU treated group. Docosanoic acid (C-22:0) was most significantly altered in ß-thalassemia as compared to healthy at p-value of 8.3 × 10-09 while erucic acid (C-22:1 Δcis-13) can be used as potential marker of HU prognosis because its level became significantly dissimilar at p-value of 3.7 × 10-04 in same patients in response to HU. However, nervonic acid (C-24:1 Δcis-15) was found to be the key player in effectively separating three groups. CONCLUSION: In inference, we have noticed that HU therapy also rectifies the serum fatty acid profile in addition to its reported affect i.e. HbF induction in ß-thalassemia patients.

Cost-effectiveness of using Quantiferon Gold (QFT-G)® versus tuberculin skin test (TST) among U.S. and foreign born populations at a public health department clinic with a low prevalence of tuberculosis.

OBJECTIVE: The purpose of this study was to determine the cost benefit to routinely using QFT-G versus the standard TST for screening U.S. and foreign born populations at a public health department clinic with a low prevalence of tuberculosis. DESIGN AND SAMPLE: A comparative cost analysis of the monetization between QFT-G and TST was conducted: Data from the health department's Chest Clinic patients seen in 2007 were used to model cost predictions. MEASURES: The net costs of screening, x-rays, the standard 9 months of latent tuberculosis infection treatment, laboratory, and administration for U.S. born patients and foreign born patients were investigated. RESULTS: There are no apparent cost savings for U.S. born individuals, but due to the higher specificity of QFT-G for foreign born BCG-vaccinated individuals, there are unnecessary expenditures associated with the higher number of false positives incurred when using TST compared with QFT-G on 1,000 foreign born individuals (69%, 18%). CONCLUSION: QFT-G is cost-effective and should be used at local health department clinics that want to achieve savings in screening and treating those suspected of having TB infection, especially for high-risk populations such as foreign born individuals.

Exploring Volunteer Pharmacists' Experiences in Responding to 2023 Türkiye Earthquakes: A Qualitative Phenomenological Study.

OBJECTIVE: Pharmacists are vital in disaster response efforts, dispensing essential medications, managing pharmacy services, consulting, and educating survivors regarding their medications. Their contributions, however, are often underrepresented in scientific literature. This study aimed to explore the experiences of pharmacists who provided pharmacy services to meet the pharmaceutical needs of the survivors after 2 major earthquakes in Türkiye in 2023. METHODS: This study adopted a phenomenological approach. Data were collected using semi-structured interviews. Purposive sampling was used to invite pharmacists who provided pharmacy services to survivors. Interview transcripts were analyzed following an inductive, reflexive thematic analysis. RESULTS: In total, 15 pharmacists were interviewed. Four main overarching themes "response to the earthquake," "preparedness for the earthquake," "experiences during service delivery," and "mental and physical experiences" were developed. CONCLUSIONS: From participants' experiences, it is essential to expand the clinical responsibilities of pharmacists and train them in providing wound care, administering immunization, and prescribing. Pharmacists should be integrated as essential members of disaster health teams. International health organizations, nongovernmental organizations, and governments are encouraged to work collaboratively and develop disaster management plans including pharmacists in early responders. This might help mitigate the deficiencies and overcome challenges in health-care systems to provide effective patient-centered care by health professionals and respond effectively to disasters.

The Association between Water, Sanitation, Hygiene, and Child Underweight in Punjab, Pakistan: An Application of Population Attributable Fraction.

Background: Access to safe drinking water, sanitation, and hygiene (WASH) facilities is crucial for health and human rights, impacting nutrition and weight. Methods: Multiple Indicators Cluster Survey (MICS) 2017-18 has been used in this study to examine the association between WASH and underweight, alongside other factors. Analysis included descriptive statistics, association tests, logistic regression, and population-attributable fractions (PAF). Results: According to results child were 1.8, 1.1 and 1.04 times less likely to be underweight if they had access to improved source of drinking water, improved sanitation and hygiene facilities respectively. The likelihood of child being underweight reduces by 1.4, 1.89, 2.01 and 2.55 times if the household wealth status increases from poorest to second, middle, fourth and richest wealth quintiles, respectively. As the mothers' education level increases from no schooling to primary, middle, secondary, and higher level, the possibility of child being underweight reduces by 1.22, 1.24, 1.60 and 2.01 times, respectively. Moreover, the likelihood of a child being underweight decreases as the education level of the household head improves. If maternal age is less than 20 or more than 35 years the likelihood of the child being underweight is increased by 1.074 and 1.121 times, respectively. A child is 1.1 times more likely to be underweight if birth spacing is less than 2 years. A child's risk of being underweight decreases by 1.1 times if they have not experienced diarrhea. A child who has never been breastfed has 1.3 times higher risk of being underweight. The results of Population Attributable Fraction (PAF) indicate that holding the other factors constant, approximately 36.46% burden of underweight was preventable by access to improved drinking water, sanitation, and hygiene practices. Conclusion: Comprehensive strategy is needed that focuses on improving access to safe drinking water, sanitation infrastructure, and hygiene behaviors.

Questionnaire-Based Study of 392 Women in Abbottabad, Pakistan, to Evaluate the Types of Cosmetic Products Purchased Between December 2018 and March 2019 and Their Associated Adverse Events.

BACKGROUND Cosmetics are applied topically to enhance appearance and are commonly used by women of all ages. Cosmetics contain many chemical agents, but the incidence of adverse reactions is low, possibly due to underreporting. This questionnaire-based study included 392 women to evaluate information on the types of cosmetics purchased between December 2018 and March 2019, their use by the women surveyed, and their associated adverse events. MATERIAL AND METHODS A cross-sectional study was conducted among 392 women in Abbottabad, Pakistan, using a pre-structured and validated questionnaire to evaluate information on the types of cosmetics, their use, and their associated adverse events. Part 1 of the study collected information about demographics. Part 2 contained a total of 11 items, and collected the frequency of use of cosmetic on skin and hair care products. Part 3 consisted of 4 items and collected information about problems encountered due to the use of cosmetics. RESULTS In the winter season, 47.7% (n=187) of women preferred chemical-based cosmetic products, while 30.9% (n=121) preferred Ayurvedic products. Among commonly used cosmetic products, 26.9% (n=106) of women used foundations. The most frequently used skin care product was face wash 39.5% (n=155). The most prevalent adverse events related to cosmetics were pimples (19.9%, n=78), redness (17.6%, n=69), and eye discomfort (15.8%, n=62). Furthermore, 51.3% (n=201) strongly agreed that cosmetics aid in getting a whiter complexion. CONCLUSIONS The survey concluded that most women preferred cosmetics with a chemical base, which are associated with rashes, redness, and acne. It is important to encourage cosmetovigilance and awareness campaigns among cosmetic product sellers and users.

Impact of pharmacist-delivered interventions on pain-related outcomes: An umbrella review of systematic reviews and meta-analyses.

INTRODUCTION: Pain is a significant healthcare challenge, impacting millions worldwide. Pharmacists have increasingly taken on expanded roles in managing pain, particularly in primary and ambulatory care contexts. This umbrella review aims to systematically evaluate evidence from published systematic reviews that explore the impact of pharmacist-delivered interventions on clinical, humanistic, and economic outcomes related to pain. METHODS: A systematic search was conducted across six electronic databases, including Ovid Embase, MEDLINE, CINAHL, Scopus, CENTRAL, APA PsycINFO, and DARE, from inception until June 2023. Prior to inclusion, two independent reviewers assessed study titles and abstracts. Following inclusion, an assessment of the methodological quality of the included studies was conducted. AMSTAR 2 was used to evaluate the methodological quality of the included SRs. RESULTS: From 2055 retrieved titles, 11 systematic reviews were included, with 5 out of 11 being meta-analyses. These SRs encompassed diverse pharmacist-led interventions such as education, medication reviews, and multi-component strategies targeting various facets of pain management. These findings showed favorable clinical outcomes, including reduced pain intensity, improved medication management, enhanced overall physical and mental well-being, and reduced hospitalization durations. Significant pain intensity reductions were found due to pharmacists' interventions, with standardized mean differences (SMDs) ranging from -0.76 to -0.22 across different studies and subgroups. Physical functioning improvements were observed, with SMDs ranging from -0.38 to 1.03. Positive humanistic outcomes were also reported, such as increased healthcare provider confidence, patient satisfaction, and quality of life (QoL). QoL improvements were reported, with SMDs ranging from 0.29 to 1.03. Three systematic reviews examined pharmacist interventions' impact on pain-related economic outcomes, highlighting varying cost implications and the need for robust research methodologies to capture costs and benefits. CONCLUSION: This umbrella review highlights the effectiveness of pharmacist-delivered interventions in improving clinical, humanistic, and economic outcomes related to pain management. Existing evidence emphasises on the need to integrate pharamacists into multi-disciplinary pain management teams. Further research is needed to investigate innovative care models, such as pharmacist-independent prescribing initiatives within collaborative pain management clinics.

Current Use and Barriers to Point-of-Care Ultrasound in Rheumatology: A National Survey of VA Medical Centers.

INTRODUCTION: Point-of-care ultrasound (POCUS) can assist rheumatologists in monitoring disease activity, establishing diagnoses, and guiding procedural interventions. POCUS use has been increasing, but little is known about current use and barriers among rheumatologists. The purpose of this study was to characterize current POCUS use, training needs, and barriers to use among rheumatologists in practice. METHODS: A prospective observational study of all Veterans Affairs (VA) medical centers was conducted using a web-based survey sent to all chiefs of staff and rheumatology chiefs about current POCUS use, training needs, barriers, and policies. RESULTS: All chiefs of staff (n = 130) and rheumatology chiefs at VA medical centers (n = 95) were surveyed with 100% and 84% response rates, respectively. The most common diagnostic POCUS applications were evaluation of synovitis, joint effusion, tendinopathies, bursitis, and rotator cuff. The most common procedural applications were arthrocentesis and joint, bursa, and tendon injection. Most rheumatology chiefs (69%) expressed interest in training for their group. The most common barriers to POCUS use were lack of trained providers (68%), funding for training (54%), training opportunities (38%), funding for travel (38%), and ultrasound equipment (31%). Lack of POCUS infrastructure was common, and few facilities had POCUS policies (20%), image archiving (25%), or quality assurance processes (6%). CONCLUSION: Currently, half of rheumatology groups use diagnostic and procedural ultrasound applications. Most rheumatology groups desire training, and lack of training and equipment were the most common barriers to ultrasound use. Deliberate investment is needed in ultrasound training and infrastructure for systematic adoption of POCUS in rheumatology. Graphical Abstract available for this article.

Logic model for opioid safety in chronic non-malignant pain management, an in-depth qualitative study.

BACKGROUND: Opioids are commonly used for the management of chronic non-malignant pain in Pakistan; but there is a lack of literature around precursors or motivators in the use of opioids. AIM: The study holistically explored factors contributing towards the unsafe use of opioids and identifies strategies to overcome them. METHOD: Exploratory qualitative methods using interviews, focus groups and non-participant observational case studies were used. Interviews and focus groups were carried out face-to-face as well as virtually and observations were conducted in community pharmacies in Islamabad and Khyber Pukhtoon Khuwa province, Pakistan. Data were collected from 4 stakeholder groups; pharmacy policy makers (n = 11), people with chronic non-malignant pain (n = 14), doctors (n = 31) and community pharmacists (n = 36) by purposive critical case sampling method. Data were analysed inductively using reflexive thematic analysis and then deductively mapped to a social ecological framework. Non-participant observations were analysed using a cross case synthesis using explanation building technique. Data from all three methods were triangulated to develop a logic model. RESULTS: Identified factors at macro (regulation), meso (social perceptions of pain and opioids) and micro levels (uncontrolled pain, self-medication, health literacy) and strategies are presented holistically and were used to develop a logic model for the prevention and mitigation of factors currently causing unsafe use of opioids. CONCLUSION: The study provides an in-depth view of factors contributing towards diversion of pharmaceutical opioids and can help guide national and international policy makers in their future initiatives to promote safe use of opioids in the management of chronic non-malignant pain in Pakistan.
