Abstract
Background Telemedicine (TM) has been seldom used for the care of persons with HIV. However, the COVID-19 pandemic has forced HIV clinics to rapidly scale TM resources. With the increase of TM, the impact on HIV patient care remains uncertain. The purpose of this study is to examine the effects of TM on HIV care and retention at a Ryan White-funded clinic. Methods This was a retrospective study of patients seen at an academic clinic in Pittsburgh, PA between 1/1/20 – 12/31/20. Encounter information was extracted from the clinic electronic health record. Primary outcomes were viral load (VL) suppression (< 200 copies/ml) and retention in care for persons seen via TM (phone, video +/- in person) vs those seen in-person. Secondary outcomes included flu vaccination and STI screening rates. Results Amongst 1414 patients, 608 patients had at least one scheduled TM visit, with 97 seen exclusively via TM, and 806 were scheduled for only in-person visits. In those with at least one TM visit, 92.72% had a suppressed VL. 89.69% of those with only TM visits were suppressed. 92.43% were suppressed in the in-person group. Average show rate amongst patients who had at least one TM visit was 60.39% (+0.96% from 2019, +1.71% from 2018), vs 64.38% amongst patients who only had in-person visits. Amongst patients who were only scheduled for TM visits, show rate was 83.97%. 40.18% of patients who had at least one TM visit received their flu vaccine in 2020 (-37.45% from 2019, -36.72% from 2018) vs 37.62% who were only seen in-person. Amongst patients who had at least one TM visit, syphilis screening rate was 43.09% (-7.64% from 2019, -8.55% from 2018) vs 43.51% for those seen only in-person. Gonorrhea and chlamydia screening rates were both 42.91% (+9.46% from 2019, +15.27% from 2018 for chlamydia screening; +8.36% from 2019, +14.73% from 2018 for gonorrhea screening). Amongst patients who were exclusively seen in-person gonorrhea screening rate was 48.24% and chlamydia screening rate was 47.57%. Table 1. Characteristics of Patients Seen in 2020 ![]()
Table 2. Primary and Secondary Outcomes for Patients Seen in 2020 ![]()
Conclusion VL suppression rates were similar across both groups, but retention in care was highest in the TM-only group. Flu vaccination rates and STI screening were lower in the groups that included TM. TM is an effective method for maintaining VL suppression and retention in care but has room for improvement with provision of preventative services. Disclosures All Authors: No reported disclosures

Abstract
Abstract
Background
Telemedicine (TM) can provide specialty ID care for remote and underserved areas; however, the need for dedicated audio-visual equipment, secure and stable internet connectivity, and local staff to assist with the consultation has limited wider implementation of synchronous TM. ID e-consults (ID electronic consultations or asynchronous™) are an alternative but data are limited on their effectiveness, especially patient outcomes.
Methods
In the setting of the COVID-19 pandemic and ID physician outage, we were asked to perform ID e-consults at a 380-bed tertiary care hospital located in Blair County, PA. We performed retrospective chart reviews of 121 patients initially evaluated by ID e-consults between April 2020 and July 2020. Follow-up visits were also conducted via e-consults with or without direct phone calls with the patient. Key patient outcomes assessed were length of stay (LOS), disposition after hospitalization, 30-day mortality from initial ID e-consult and 30-day readmission post-discharge.
Results
The majority of patients were white males and non-ICU (Table 1). The most common ID diagnosis was bacteremia (27.3%, 33/121), followed by skin and soft tissue infections (15.7%, 19/121) and bone/joint infections (14.9%, 18/121) (Figure 1). Table 2 shows patient outcomes. Average total LOS was 11 days and 7 days post-initial ID e-consult. 48.7% (59/121) of patients were discharged home and 37.2% (45/121) to a post-acute rehabilitation facility. 2.5% (3/121) of patients required transfer to a higher level of care facility; none of which were to obtain in-person ID care. The index mortality rate was 3.3% (4/121), which appears to be lower than published data for in-person ID care. The 30-day mortality rate was 4.1% (5/121), which is also comparable to previously reported for ID e-consults. 25.6% (31/121) of patients required readmission within 30 days but only 14.0% (17/121) were related to the initial infection.

Table 2. Outcomes
Conclusion
We believe that this is the first report of the implementation of ID e-consults at a tertiary care hospital. Mortality rates appear to be comparable to in-person ID care. In the absence of in-person ID physicians, ID e-consults can be a reasonable substitute. Further study is required to compare performance of ID e-consults to in-person ID consults.

Abstract
BACKGROUND AND PURPOSE Asymmetries in the circle of Willis have been associated with several conditions, including migraines and stroke, but they may also be age-dependent. This study examined the impact of age and age-dependent changes in cerebral perfusion on circle of Willis anatomy in healthy children and adults. MATERIALS AND METHODS We performed an observational, cross-sectional study of bright and black-blood imaging of the proximal cerebral vasculature using TOF-MRA and T2 sampling perfection with application-optimized contrasts by using different flip angle evolution (T2-SPACE) imaging at the level of the circle of Willis in 23 healthy children and 43 healthy adults (4-74 years of age). We compared arterial diameters measured manually and cerebral perfusion via pseudocontinuous arterial spin-labeling between children and adults. RESULTS We found that the summed cross-sectional area of the circle of Willis is larger in children than in adults, though the effect size was smaller with T2-SPACE-based measurements than with TOF-MRA. The circle of Willis is also more symmetric in children, and nonvisualized segments occur more frequently in adults than in children. Moreover, the size and symmetry of the circle of Willis correlate with cerebral perfusion. CONCLUSIONS Our results demonstrate that the circle of Willis is different in size and symmetry in healthy children compared with adults, likely associated with developmental changes in cerebral perfusion. Further work is needed to understand why asymmetric vasculature develops in some but not all adults.

Abstract
Abstract
Background
Healthcare decision-makers need comprehensive evidence to mitigate surges in the demand for human resources for health (HRH) during infectious disease outbreaks, in terms of both short- and longer-term impacts. This study aimed to assess the state of the evidence to address HRH surge capacity during COVID-19 and other outbreaks of global significance in the 21st century.
Methods
We systematically searched eight bibliographic databases to extract primary research articles published between 01/2000-06/2020, capturing temporal changes in HRH requirements and responses surrounding viral respiratory infection pandemics. A systems approach was used, considering providers in hospitals, out-of-hospital systems, emergency medical services, and public health. We narratively synthesized the evidence following the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-analyses) standard.
Results
Of the 1,155 retrieved records, 16 studies met our inclusion criteria; of these, 5 focused on COVID-19, 3 on H1N1, and 8 on a hypothetical pandemic. Different training, mobilization, and redeployment options to address pandemic-time health system capacity were assessed. Few governance scenarios drew on observational HRH data allowing for comparability across contexts. Notable evidence gaps included occupational and psychosocial factors affecting healthcare workers' absenteeism and risk of burnout, gendered considerations of HRH capacity, evaluations in low- and lower-middle income countries, and policy-actionable assessments to inform post-pandemic recovery and sustainability of services for noncommunicable disease management.
Conclusions
This research emphasized the critical need for timely, internationally comparable, and equity-informative HRH data and research to enhance preparedness, response, and recovery policies for this and future pandemics. Full paper is available at: https://doi.org/10.1002/hpm.3137
Key messages
The COVID-19 pandemic has highlighted the critical need for enhanced health workforce data and research, including better tracking of demographics, exposures, infections and deaths of health workers. Although women comprise 70% of the health workforce in many countries, gender-blindness persists in the global literature on health workforce research and governance in public health emergencies./bodyt

Abstract
Abstract
Background
Pseudoaneurysms of visceral arteries are uncommon, with a prevalence of 0.01% to 0.2%1. Initial treatment is radiological embolisation (RE)2. If this fails, surgical access to the pseudoaneurysm is extremely difficult. They are associated with major complications such as rupture, ischaemia and shock2, with a 20-70% mortality rate3. We report the case of a patient admitted with a life-threatening bleed from an aberrant inferior pancreaticoduodenal artery (IPDA) with failed RE.
Case Summary
A 44-year-old patient presented with right upper quadrant pain, shock and low haemoglobin. His computerised tomography (CT) scan showed a large retroperitoneal haematoma with active bleeding from a 5x6mm IPDA pseudoaneurysm. After resuscitation, access to the IPDA during RE via the coeliac axis and superior mesenteric artery was unsuccessful and he deteriorated. He underwent an emergency laparotomy, which showed the retro-peritoneal haematoma had ruptured into the peritoneal cavity through the transverse mesocolon. Four-quadrant abdominal packing and supra-coeliac manual compression of the aorta was utilised. The right colon was mobilised with full kocherisation of the duodenum. The gastrocolic omentum was divided to enter the lesser sac. The haematoma was evacuated and bleeding branches from the IPDA were suture ligated. He required 26 units of blood throughout admission and underwent 24-hour damage control laparostomy on intensive care. CT mesenteric angiogram post-surgery and re-look laparotomy showed no further active bleeds. He had an uneventful recovery and discharged safely.
Conclusions
RE of visceral artery pseudoaneurysms is challenging. Surgery remains the last resort and should be performed by appropriately trained specialist surgeons.

Noncontrast MRI Protocol for Selected Pediatric Pituitary Endocrinopathies: A Procedure with High Diagnostic Yield and Potential to Reduce Anesthesia and Gadolinium-Based Contrast Exposure. AJNR Am J Neuroradiol 2021; 42:1884-1890.

Abstract
BACKGROUND AND PURPOSE Although many pediatric neuroradiology practices empirically use noncontrast brain and pituitary MR imaging for evaluation of growth hormone deficiency, central precocious puberty, and short stature, there are currently insufficient published data to support this practice in an evidence-based fashion. Therefore, the use of contrast-enhanced MR imaging for all pediatric pituitary endocrinopathies remains widespread. We evaluated whether noncontrast MR imaging has adequate diagnostic yield for the evaluation of pediatric growth hormone deficiency, central precocious puberty, and short stature. MATERIALS AND METHODS Pituitary MR imaging studies obtained for growth hormone deficiency, central precocious puberty, or short stature in patients 0-18 years of age from 2010 to 2019 were analyzed. Separate blinded review of noncontrast images in cases with abnormalities on the original radiology report was performed by 2 subspecialty-trained pediatric neuroradiologists, with discrepancies resolved by consensus. RESULTS Of the 134/442 MR imaging studies obtained for growth hormone deficiency, central precocious puberty, or short stature with hypothalamic-pituitary region abnormalities, there was 70% concordance with the original reports on blinded review of noncontrast images. Twenty-two of 40 discrepancies were deemed unrelated to the indication, and 9 cases originally interpreted as possible microadenoma were read as having normal findings on blinded review. Only 9 of 40 discrepancies required contrast for further characterization. CONCLUSIONS In our study, most relevant radiologic findings in patients with growth hormone deficiency, central precocious puberty, and short stature were detectable without contrast, providing evidence that contrast can be avoided in routine MR imaging evaluation of these indications. We propose a "rapid noncontrast pituitary" MR imaging protocol for pediatric patients presenting with growth hormone deficiency, central precocious puberty, or short stature, which may increase efficiency and decrease contrast and anesthesia exposure.

Abstract
AIM To ascertain the predictors of remission and relapse in patients of Cushing's disease (CD) undergoing pituitary transsphenoidal surgery (TSS). METHODS Patients with CD subjected to TSS over 35 years at a tertiary care center were included. Patients were grouped into remission and persistent disease at 1 year after surgery, and were further followed up for relapse. Demographic, clinical, biochemical, histological, radiological and post-operative follow-up parameters were analyzed. RESULTS Of the 152 patients of CD, 145 underwent TSS. Remission was achieved in 95 (65.5%) patients at 1 year. Patients in remission had shorter duration of symptoms prior to presentation (p = 0.009), more frequent presence of proximal myopathy (p = 0.038) and a tumor size of < 2.05 cm (p = 0.016) in comparison to those with persistent disease. Post-TSS, immediate post-operative 0800-h cortisol (< 159.85 nmol/L; p = 0.001), histological confirmation of tumor (p = 0.045), duration of glucocorticoid replacement (median 90 days; p = 0.001), non-visualization of tumor on MRI (p = 0.003), new-onset hypogonadism (p = 0.001), 3-month 0800-h cortisol (< 384.9 nmol/L; p = 0.001), resolution of diabetes (p = 0.001) and hypertension (p = 0.001), and recovery of hypothalamic-pituitary-adrenal axis (p = 0.018) favored remission. In logistic regression model, requirement of glucocorticoid replacement (p = 0.033), and resolution of hypertension post-TSS (p = 0.003) predicted remission. None of the parameters could predict relapse. CONCLUSION The study could ascertain the predictors of remission in CD. Apart from the tumor characteristics, surgical aspects and low post-operative 0800-h cortisol, the results suggest that baseline clinical parameters, longer glucocorticoid replacement, and resolution of metabolic complications post-TSS predict remission in CD. Long-term follow-up is essential to look for relapse.

Abstract
OBJECTIVES A retrospective study was undertaken to investigate the circulating dengue virus (DENV) serotypes and genotypes in India in 2018. METHODS In total, 4963 samples referred to virus research diagnostic laboratories (n=21), the Indian Council of Medical Research-National Institute of Virology (ICMR-NIV) and ICMR-NIV field units (n=2) for diagnosis of dengue in 2018 were tested using a real-time reverse transcription polymerase chain reaction assay for the presence of DENV serotypes. Representative samples were sequenced for the envelope (E) gene. RESULTS Regional diversity was observed with regard to the dominant circulating serotypes. DENV-2 was found to be the most common serotype in many states. Thrombocytopenia, petechiae and malaise were associated with DENV-2 infection. Phylogenetic analyses of DENV E gene sequences revealed the circulation of genotypes I and V of DENV-1, two lineages of DENV-2 genotype IV, DENV-3 genotype III and DENV-4 genotype I. CONCLUSIONS This study found regional differences in the prevalence of circulating DENV serotypes in India, and provides baseline data for continuous molecular surveillance. Molecular surveillance may have implications for predicting large-scale outbreaks of dengue if regional shifts in the predominantly circulating serotypes and genotypes are detected during the early phase of the dengue season.

Abstract
Objective To study the presence of isthmocele in post-cesarean women using USG and MRI and its correlation with risk factors. Method This was a prospective observational study. A total of 90 patients were enrolled at the time of discharge of cesarean delivery and were advised to come for follow-up at 3-4 months for detection of isthmocele. A total of 82 patients reported for follow-up, and TVS and MRI Pelvis were done for visualization of isthmocele. If isthmocele was diagnosed, its correlation with risk factors was studied. Results On TVS isthmocele was present in 11 patients and on MRI in 16 patients. Detection rate was 77.07% in comparison with previous studies. Compared to MRI, sensitivity of USG was 68.75%; however, the specificity and positive predictive value for both were 100%. The negative predictive value for USG compared to MRI was 92.96%. Shape of the isthmocele was triangular in most women. Obesity, prior history of cesarean delivery, elective cesarean, gestational diabetes, preeclampsia and prolonged active labor were associated with development of isthmocele. Conclusion The study concluded that yield of diagnosis of isthmocele by MRI was better than TVS but not statistically significant. Further study with large sample size is needed to identify the best tool for diagnosis of isthmocele. Obesity, gestational diabetes, preeclampsia, prior history of cesarean, elective cesarean and prolonged active labor were associated with development of isthmocele.

Abstract
Wheat is the second most cultivated cereal crop in the world and is an important crop in India. Leaf (brown) rust, caused by Puccinia triticina, was the most prevalent among the three rusts found in all the wheat-growing areas of India, Bhutan, and Nepal during 2016 to 2019. Leaf rust samples from wheat crops in these countries were pathotyped using the wheat differential genotypes and binomial Indian system of nomenclature. To facilitate international communication, each pathotype identified was also tested using the North American differentials. A total of 33 pathotypes were identified from 1,086 samples, including three new pathotypes: 61R47 (162-5 = KHTPM) and 93R49 (49 = NHKTN) from India and 93R57 (20-1 = NHKTN) from Nepal. Two pathotypes, 121R60-1 (77-9/52 = MHTKL) and 121R63-1 (77-5 = THTTM), accounted for 79.46% of the population. Virulence on Lr19 was identified in 0.27% of the samples from Nepal only. The proportion of pathotype 121R60-1 (77-9 = MHTKL) increased to 57.55% during these years. Virulence was not observed on Lr9, Lr24, Lr25, Lr28, Lr32, Lr39, Lr45, and Lr47 in the population of the Indian subcontinent. Eighteen polymorphic simple sequence repeat (SSR) primer pairs tested on the isolates amplified 48 alleles with an average of 2.66 alleles per primer pair. Based on SSR genotyping, these pathotypes could be grouped into two clades with another two subclades each. Many of the Lr genes present in Indian wheat germplasm (Lr1, Lr3a, Lr10, Lr11, Lr14a, Lr15, Lr16, Lr17, Lr20, Lr23, and Lr26) were ineffective for a majority of pathotypes. Most of these varieties possessed a high degree of leaf rust resistance. The field resistance of wheat varieties could be attributed to the interaction of genes, unknown resistance, or adult plant resistance.

Abstract
PURPOSE To present the data on primary hyperparathyroidism (PHPT) in pregnancy from India obtained from a large database maintained over 15 years. METHODS We retrieved data of all women with gestational PHPT from the Indian PHPT registry between July 2005 and January 2020, and compared their clinical, biochemical, and other characteristics with age-matched non-pregnant women with PHPT. RESULTS Out of 386 women, eight had gestational PHPT (2.1%). The common presenting manifestations were acute pancreatitis (50%) and renal stone disease (50%); two were asymptomatic. Five women (62.5%) had a history of prior miscarriages. Seven patients (88%) had preeclampsia during the present gestation. Serum calcium and intact parathyroid hormone (iPTH) were not statistically different from the age-matched non-pregnant PHPT group. Six patients with mild-to-moderate hypercalcemia were medically managed with hydration with/without cinacalcet while one patient underwent percutaneous ethanol ablation of the parathyroid adenoma; none underwent surgery during pregnancy. Mean serum calcium maintained from treatment initiation till delivery was 10.5 ± 0.4 mg/dl. One patient had spontaneous preterm delivery at 36 weeks; the remaining patients had normal vaginal delivery at term. None had severe preeclampsia/eclampsia. Fetal outcomes included low birth weight in three newborns (37.5%); two of them had hypocalcemic seizures. CONCLUSION The prevalence of gestational PHPT was 2.1% in this largest Indian PHPT cohort, which is higher than that reported from the West (< 1%). Gestational PHPT can lead to preeclampsia and miscarriage. Pregnant PHPT patients with mild-to-moderate hypercalcemia can be managed with hydration/cinacalcet; however, long-term safety data and large-scale randomized controlled trials are required.

Abstract
CONTEXT Anorexia nervosa (AN) is prevalent in adolescent girls and is associated with bone impairment driven by hormonal alterations in nutritional deficiency. OBJECTIVE To assess the impact of estrogen replacement with and without recombinant human insulin-like growth factor-1 (rhIGF-1) administration on bone outcomes. DESIGN Double-blind, randomized, placebo-controlled 12-month longitudinal study. PARTICIPANTS Seventy-five adolescent and young adult women with AN age 14 to 22 years. Thirty-three participants completed the study. INTERVENTION Transdermal 17-beta estradiol 0.1 mg/day with (i) 30 mcg/kg/dose of rhIGF-1 administered subcutaneously twice daily (AN-IGF-1+) or (ii) placebo (AN-IGF-1-). The dose of rhIGF-1 was adjusted to maintain levels in the upper half of the normal pubertal range. MAIN OUTCOME MEASURES Bone turnover markers and bone density, geometry, microarchitecture, and strength estimates. RESULTS Over 12 months, lumbar areal bone mineral density increased in AN-IGF-1- compared to AN-IGF-1+ (P = 0.004). AN-IGF-1+ demonstrated no improvement in areal BMD in the setting of variable compliance to estrogen treatment. Groups did not differ for 12-month changes in bone geometry, microarchitecture, volumetric bone mineral density (vBMD), or strength (and results did not change after controlling for weight changes over 12 months). Both groups had increases in radial cortical area and vBMD, and tibia cortical vBMD over 12 months. Levels of a bone resorption marker decreased in AN-IGF-1- (P = 0.042), while parathyroid hormone increased in AN-IGF-1+ (P = 0.019). AN-IGF-1- experienced irregular menses more frequently than did AN-IGF-1+, but incidence of all other adverse events did not differ between groups. CONCLUSIONS We found no additive benefit of rhIGF-1 administration for 12 months over transdermal estrogen replacement alone in this cohort of young women with AN.

Abstract
Periodontitis, a multiple pathogen disease has the latest addition to the family i.e. Escherichia coli as a potential and emerging periodontal pathogen owing to its lipopolysaccharide more potent than Porphyromonas gingivalis, which makes it an emerging threat in periodontal disease. The role of antimicrobial agents in the management of periodontal diseases is of utmost importance. However, in the present scenario, antibiotic resistance is a public health concern now and there are very few options left for treatment. So, honey, a pioneer in traditional medicine was tried in the treatment against Escherichia coli to evaluate and compare the "in-vitro" antibacterial activity and efficacy of raw and commercial honey at different concentrations in comparison to tetracycline as a control on patient-isolated Escherichia coli and the American Type Culture Collection (ATCC) Escherichia coli 25922 strain from 5th Aug 2018 to 15th Feb 2019 at the Department of Microbiology, Rama Medical College, Kanpur (UP), India. In the in-vitro study different concentrations (100%, 75%, 50% and 25% v/v) of raw and commercial honey were studied and sensitivity tests were used to evaluate their antibacterial effect on patient-isolated Escherichia coli and the ATCC Escherichia coli 25922 strain. Minimum inhibitory concentration (MIC) and Minimum bactericidal concentration (MBC) were also determined for raw honey, and commercial honey in comparison to tetracycline. In case of raw honey, zone of inhibition was seen at 100%, 75% and 50% concentration, with maximum inhibition being 27±1.154mm and 23±0.666mm for patient-isolated Escherichia coli and ATCC Escherichia coli 25922 strain respectively at 100% concentration, whereas, the commercial honey was effective only at 100% and 75% concentration, with maximum inhibition zone of 13±1.054mm and 17±0.942mm at 100% concentration on patient-isolated Escherichia coli and ATCC Escherichia coli 25922 strain respectively. However, no effect was observed at 25% concentration for both raw and commercial honey. The MIC and MBC of raw and commercial honey were determined by the broth dilution method, where raw honey exhibited both MIC and MBC at 512 mg/ml whereas, and commercial honey exhibited MIC at 512mg/ml and MBC at 1024 mg/ml respectively. While comparing the zone of inhibition of raw and commercial honey, it was observed that the raw honey showed almost equivalent potency and efficacy as compared to a positive control tetracycline (2.5%). There was statistically significant difference (p≤0.01) in zone of inhibition of raw and commercial honey at 100% concentration on patient-isolated Escherichia coli and ATCC Escherichia coli 25922 strain. Antimicrobial activity of raw honey at 100% concentration was equivalent to that of tetracycline and was significantly better than commercial honey.

Abstract
The spectral band covering ∼8-12µm is atmospherically transparent and therefore important for terrestrial imaging, day/night situational awareness systems, and spectroscopic applications. There is a dearth of tunable filters spanning the band. Here, we propose and demonstrate a new, to the best of our knowledge, tunable-filter method engaging the fundamental physics of the guided-mode resonance (GMR) effect realized with a non-periodic lattice. The polarization-dependent filter is fashioned with a one-dimensional Ge grating on a ZnSe substrate and interrogated with a ∼1.5mm Gaussian beam to show clear transmittance nulls. To expand the tuning range, the device parameters are optimized for sequential operation in TM and TE polarization states. The theoretical model exhibits a tunable range exceeding 4 µm, thus covering the band fully. In the experiment, a prototype device exhibits a spectral range of 8.6-10.0 µm in TM and 9.9-11.7 µm in TE polarization or >3µm total. With additional efforts in fabrication, we expect to achieve the full range.

Abstract
The American Advancing Kidney Health Initiative has renewed interest in home hemodialysis (HHD). Many perceived barriers exist for adoption of HHD despite well-reported clinical benefits. A well-designed program ensures patient success further engaging more patients. The initial planning regarding the surrounding patient population, stakeholders, economics, and physical location is essential. The services offered including modality education and different kinds of HHD modalities depend on local expertise and economics. The program should fulfill conditions for coverage requirements for personnel, physical infrastructure, and quality metrics to begin operations. The patient recruitment is facilitated by a patient-centric modality education program developed by the multidisciplinary team. If the patient is interested, a training schedule should be discussed with the patient and caregiver. A system to ensure remote patient monitoring, respite care, and 24 hours on-call availability should be established. These practical considerations ensure initial success and future growth of the program.
