Ambulatory antibiotic prescription rates for acute respiratory infection rebound two years after the start of the COVID-19 pandemic.

BACKGROUND: During the COVID-19 pandemic, acute respiratory infection (ARI) antibiotic prescribing in ambulatory care markedly decreased. It is unclear if antibiotic prescription rates will remain lowered. METHODS: We used trend analyses of antibiotics prescribed during and after the first wave of COVID-19 to determine whether ARI antibiotic prescribing rates in ambulatory care have remained suppressed compared to pre-COVID-19 levels. Retrospective data was used from patients with ARI or UTI diagnosis code(s) for their encounter from 298 primary care and 66 urgent care practices within four academic health systems in New York, Wisconsin, and Utah between January 2017 and June 2022. The primary measures included antibiotic prescriptions per 100 non-COVID ARI encounters, encounter volume, prescribing trends, and change from expected trend. RESULTS: At baseline, during and after the first wave, the overall ARI antibiotic prescribing rates were 54.7, 38.5, and 54.7 prescriptions per 100 encounters, respectively. ARI antibiotic prescription rates saw a statistically significant decline after COVID-19 onset (step change -15.2, 95% CI: -19.6 to -4.8). During the first wave, encounter volume decreased 29.4% and, after the first wave, remained decreased by 188%. After the first wave, ARI antibiotic prescription rates were no longer significantly suppressed from baseline (step change 0.01, 95% CI: -6.3 to 6.2). There was no significant difference between UTI antibiotic prescription rates at baseline versus the end of the observation period. CONCLUSIONS: The decline in ARI antibiotic prescribing observed after the onset of COVID-19 was temporary, not mirrored in UTI antibiotic prescribing, and does not represent a long-term change in clinician prescribing behaviors. During a period of heightened awareness of a viral cause of ARI, a substantial and clinically meaningful decrease in clinician antibiotic prescribing was observed. Future efforts in antibiotic stewardship may benefit from continued study of factors leading to this reduction and rebound in prescribing rates.

The complete mitochondrial genome of Penicillium expansum: Insights into the fungal evolution and phylogeny.

Penicillium expansum is an important phytopathogenic fungus that causes blue mold disease. In this study, the novel mitochondrial genome of P. expansum was sequenced, assembled, annotated, and compared with the previously published Penicillium mitogenomes. P. expansum mitogenome is composed of circular DNA molecules with a genome size of 25,496 bp. It encodes 16 protein-encoding genes (PCGs), two rRNA genes, and 25 tRNA genes. Comparative analysis with six other Penicillium species revealed that gene length, GC content, AT skew, and GC skew were variable among the core protein-coding genes. The Penicillium species' gene synteny analysis identified several gene rearrangements. Among the core 15 PCGs, atp8 had the lowest K2P genetic distance, which shows that this gene is highly conserved. The Ka/Ks value of most PCGs was less than 1, which shows that these genes have undergone purifying selection. Phylogenetic analysis based on 14 concatenated core mitochondrial genes revealed that P. expansum shares a close relationship with P. solitum. This study served as a first report on the complete mitochondrial genome of P. expansum and its comparative analysis that will contribute to population genetics and rapid evolutionary studies among Penicillium species.

New guidelines and therapeutic updates for the management of lupus nephritis.

PURPOSE OF REVIEW: Systemic lupus erythematosus (SLE) can be a devastating condition, striking young patients often in their prime reproductive years. Lupus nephritis is a common and serious complication occurring in roughly 50% of SLE cases, indicating a high likelihood of disease progression, morbidity, and mortality. As the early trials of steroid therapy, and later cyclophosphamide (CYC), therapeutic changes had been stagnant. Then came the introduction of mycophenolate mofetil (MMF) in the 2000s. After the Aspreva Lupus Management Study, there had been a dearth of trials showing positive therapy results. Since 2020, new studies have emerged for lupus nephritis involving the use of anti-BLYS agents, novel calcineurin inhibitors, CD20 blockade, and antiinterferon agents. Nephrology and rheumatology society guidelines in the United States and across the world are still catching up. RECENT FINDINGS: Although therapeutic guidelines are being developed, updates that have come through have focused on improved diagnostic and monitoring guidelines. One theme is the recommendation of increasingly tight proteinuria control and firmer guidelines for the rapid induction of remission. The reality of multitarget therapy and the expectation of rapid induction for a more complete remission are being widely recognized. SUMMARY: The need for more complete and more rapid induction and control of lupus nephritis is undisputed according to the evidence and guidelines, and the medications to achieve this are growing at a rate not seen over the prior two decades. What remains is a stepwise approach to recognize how to best optimize therapy. Based on available evidence, an algorithm for induction and maintenance treatment of lupus nephritis used by the University of California Irvine Lupus Nephritis clinic, is recommended.

A paradigm shift from office to home-based blood pressure measurement approaches in kidney transplant recipients.

PURPOSE OF REVIEW: The unattended blood pressure (BP) readings from home blood pressure (HBP) monitoring should provide more accurate BP readings than attended BP obtained from office blood pressure (OBP). Here, we review evidence supporting the clinical utility of HBP and automatic remote monitoring of blood pressure (ARM-BP) in kidney transplant recipients (KTR). RECENT FINDINGS: BP from 24-h ambulatory blood pressure monitoring (24-h ABPM) is higher than but better associated with kidney and cardiovascular outcomes compared to OBP and HBP. While there is discordance of BP readings across different BP measurement methods causing BP misclassification, HBP provides BP readings closer to the readings from the 24-h ABPM than those from OBP. Systolic and diastolic BP is better controlled within 30 days after utilizing ARM-BP. SUMMARY: Compared to OBP, HBP minimizes the attended effect of OBP, and its readings are closer to the gold standard 24-h ABPM. ARM-BP improves BP control in the short term and trials of longer follow-up duration are required to evaluate sustained clinical benefits in KTR. The paradigm of BP monitoring may shift toward HBP, while OBP may be utilized primarily for KTR who cannot perform HBP for hypertension diagnosis and management.

Universal EHRs Clinical Decision Support for Thromboprophylaxis in Medical Inpatients: A Cluster Randomized Trial.

Background: Thromboprophylaxis for medically ill patients during hospitalization and postdischarge remains underutilized. Clinical decision support (CDS) may address this need if embedded within workflow, interchangeable among electronic health records (EHRs), and anchored on a validated model. Objectives: The purpose of this study was to assess the clinical impact of a universal EHR-integrated CDS tool based on the International Medical Prevention Registry on Venous Thromboembolism plus D-Dimer venous thromboembolism model. Methods: This was a cluster randomized trial of 4 tertiary academic hospitals from December 21, 2020 to January 21, 2022. Inpatients over age 60 with key medical illnesses were eligible. We embedded CDS at admission and discharge. Hospitals were randomized to intervention (CDS; n = 2) vs usual care (n = 2) groups. The primary outcome was rate of appropriate thromboprophylaxis. Secondary outcomes included venous, arterial, and total thromboembolism, major bleeding, and all-cause mortality through 30 days postdischarge. Results: After exclusions, 10,699 of 19,823 patients were analyzed. Intervention group tool adoption was 77.8%. Appropriate thromboprophylaxis was increased at intervention hospitals, both inpatient (80.1% vs 72.5%, OR: 1.52, 95% CI: 1.39-1.67) and at discharge (13.6% vs 7.5%, OR: 1.93, 95% CI: 1.60-2.33). There were fewer venous (2.7% vs 3.3%, OR: 0.80, 95% CI: 0.64-1.00), arterial (0.25% vs 0.70%, OR: 0.35, 95% CI: 0.19-0.67), and total thromboembolisms (2.9% vs 4.0%, OR: 0.71, 95% CI: 0.58-0.88) at intervention hospitals. Major bleeding was rare and did not differ between groups. Mortality was higher at intervention hospitals (9.1% vs 7.0%, OR: 1.32, 95% CI: 1.15-1.53). Conclusions: EHR-embedded CDS increased appropriate thromboprophylaxis and reduced thromboembolism without increasing major bleeding in medically ill inpatients. Mortality was higher at intervention hospitals.

A rare case of the superior vena cava obstruction in a 16-year-old boy with Burkitt's lymphoma: A case report.

Burkitt's lymphoma (BL) is an aggressive non-Hodgkin B-cell lymphoma. Superior vena cava obstruction (SVCO) is considered a rare presentation of BL and it is usually associated with other types of non-Hodgkin lymphoma such as diffuse large-cell. We report a rare case of sporadic BL with SVCO in a 16-year-old boy with nasopharyngeal, mediastinal, and adrenal masses. The patient presented with a two-month history of left upper neck swelling that increased with time and was not associated with other symptoms. The patient tested positive for COVID-19 on the second day after admission. On examination, he had enlarged solitary lateral cervical and bilateral posterior auricular lymph nodes. There were no signs or symptoms of SVCO regardless of the findings suggested by the computed tomography of the chest. The patient was treated with hyper-CVAD chemotherapy and showed a remarkable resolution of the nasopharyngeal and mediastinal masses with a mild response of his adrenal mass. There were no complications detected during this patient's management.

Autosomal Dominant Polycystic Kidney Disease Prevalence among a Racially Diverse United States Population, 2002 through 2018.

Among a large racially and ethnically diverse US population, the prevalence of diagnosed ADPKD between 2002 and 2018 was 42.6 per 100,000 persons.ADPKD prevalence (per 100,000) was higher in (non-Hispanic) White (63.2) and Black (73.0) patients compared with Hispanic (39.9) and Asian (48.9) patients.Given the variable penetrance of ADPKD, our findings suggest race may be a factor in the clinical presentation and diagnosis of ADPKD.

Exploring the linkage between PM2.5 levels and COVID-19 spread and its implications for socio-economic circles.

A pneumonia-like disease of unknown origin caused a catastrophe in Wuhan city, China. This disease spread to 215 countries affecting a wide range of people. World health organization (WHO) called it a pandemic and it was officially named as Severe Acute Respiratory Syndrome Corona virus 2 (SARS CoV-2), also known as Corona virus disease (COVID-19). This pandemic compelled countries to enforce a socio-economic lockdown to prevent its widespread. This paper focuses on how the particulate matter pollution was reduced during the lockdown period (23 March to April 15, 2020) as compared to before lockdown. Both ground-based and satellite observations were used to identify the improvement in air quality of Pakistan with primary focus on four major cities of Lahore, Islamabad, Karachi and Peshawar. Both datasets have shown a substantial reduction in PM2.5 pollution levels (ranging from 13% to 33% in case of satellite observations, while 23%-58% in ground-based observations) across Pakistan. Result shows a higher rate of COVID-19 spread in major cities of Pakistan with poor air quality conditions. Yet more research is needed in order to establish linkage between COVID-19 spread and air pollution. However, it can be partially attributed to both higher rate of population density and frequent exposure of population to enhanced levels of PM2.5 concentrations before lockdown period.

Beyond Developmental Supports for a Child Refugee.

CASE: Zahid is a 10-year-old boy who moved to the United States 18 months ago with his parents and 3 younger siblings. He and his family are refugees from Syria. Zahid was born in Syria after an uncomplicated pregnancy and delivery. Zahid's parents first became concerned about Zahid's development when he was 9 months old because he had not started cooing or babbling and did not respond to his name. At 3 years, a doctor in Syria expressed concern that Zahid may have autism spectrum disorder; however, his parents did not know what symptoms triggered the concern and believed his behavior was because of his ongoing exposure to trauma.Zahid underwent a full evaluation 1 year ago in the United States and was found to meet the criteria for autism spectrum disorder. Coaching was provided to his parents in obtaining appropriate educational support for their son, and a referral was placed for applied behavior analysis (ABA) to be provided by an organization in the community. After several meetings between the parents and school administration, an Individualized Education Program was initiated. Despite acceptance into a community-based ABA program, Zahid has not begun the intervention because of transportation difficulties. In-home ABA was offered but was refused by the family.The family is under significant stress. Zahid is nonverbal and has displayed behaviors affecting safety, including wandering/eloping and turning on kitchen appliances resulting in a kitchen fire. Zahid's mother completed high school, and his father completed sixth grade. Both parents speak limited English, and neither is employed. The family receives financial support through the government, but this will be ending soon. Zahid's father is concerned that employment outside of the home will further limit his ability to transport Zahid to necessary appointments. Zahid's mother does not drive. Zahid's father requests that the physician provide a letter requesting exemption from requirements to participate in work or training programs because of Zahid's needs. How would you respond to this overwhelmed father?

ASSESSING THE KNOWLEDGE, ATTITUDES AND PRACTICES OF SCHOOL TEACHERS REGARDING DYSLEXIA, ATTENTION-DEFICIT/ HYPERACTIVITY AND AUTISTIC SPECTRUM DISORDERS IN KARACHI, PAKISTAN.

BACKGROUND: Learning impairments in children consist of a spectrum of disorders that are under diagnosed in Pakistan. Most learning disorders have long term consequences for a child and early detection is thus imperative. Teachers may be able to play a key role in such identification. The objective of our study was to survey knowledge, attitudes and practices of school teachers regarding dyslexia, Attention-deficit/hyperactivity disorder (ADHD) and autistic spectrum disorder, and assess their ability to identify learning disabilities. METHODS: A cross-sectional study was conducted with 233 primary school teachers from Karachi using a self-administered questionnaire. RESULTS: Mean scores for the knowledge test and the ability to identify learning- impaired children were 58.8% and 53.3%, respectively. Better qualified teachers scored significantly more on the knowledge and ability to identify learning impairments sections. Most teachers believed that these students should study in mainstream schools with special educators. Majority of the teachers belonged to schools where children with learning disabilities were detected using teachers' judgment. Most teachers manage these children by involving them in discussions, seating them at the front of the class, and giving them extra time. CONCLUSION: Knowledge about learning disabilities is very low amongst school teachers, which may limit their ability to identify learning impairments.

Extremely rare case of primary esophageal mucous associated lymphoid tissue lymphoma.

SJ is a 37-year-old male who presented with one year history of dysphagia, odynophagia and 15 pounds weight loss. He underwent endoscopic evaluation which showed mid esophageal ulcers. It was thought that the cause of the ulcer was the multivitamins and the patient was asked to stop them. Furthermore Esomeprazole therapy was also initiated. Patient's symptoms persisted but he did not seek any medical attention until about one year later. Meanwhile the patient reported additional 15 pounds of weight loss. We repeated upper endoscopy again which showed evidence of two chronic non bleeding irregular friable ulcerations seen in the mid esophagus, 31 cm from the incisors. Biopsies and frozen section were taken and sent for assessment to the Pathology lab. Immunoperoxidase studies on frozen sections showed the presence of IgM and for most plasma cells IgG. The microscopic and histologic findings were consistent with mucous associated lymphoid tissue lymphoma with plasmocytic differentiation. Computed tomographic scan done showed no evidence of spread to adjacent structures. The patient was referred to oncology and several cycles of radiation and Rituximab therapy were initiated which cured the disease. Subsequent endoscopies with blind biopsies were done which were negative for any neoplastic process.

A sandwich ELISA for phosphoglycerate kinase.

Phosphoglycerate kinase (PGK1) is a key enzyme in glycolysis that can also be released from certain cells. In the extracellular milieu, PGK1 reportedly acts as a disulphide reductase to activate plasmin, resulting in the production of angiostatin, a potent angiogenesis inhibitor. Certain cancer cell lines secrete unusually large amounts of PGK1, raising the possibility that serum PGK1 levels can be used to screen for cancer. To facilitate the characterization of the PGK1 secretory pathway and to monitor serum levels of PGK1, we have developed a sensitive sandwich ELISA using an immuno-affinity-purified chicken polyclonal antibody for capturing PGK1 and an immuno-affinity-purified rabbit polyclonal antibody for detecting it. The assay is about 10-fold more sensitive than other reported PGK1 ELISAs. We used the ELISA to quantify the amount of PGK1 released from HeLa cells and PGK1 serum levels in cancer patients. Of 10 cancer patients whose serum was tested, 3 of 4 with pancreatic cancer had 65-900% higher levels of PGK1 than that found in normal serum.
