Objectives: To report on the outcomes and demographics of azoospermic couples undergoing microscopic testicular sperm extraction (micro-TESE) in a large tertiary referral centre. Subjects and methods: A retrospective study of patients undergoing micro-TESE in a tertiary referral centre from March 2015 to August 2019 was undertaken. Histopathology, patient demographics, comorbidities, patient factors and live birth outcomes were evaluated. Results: A total of 102 micro-TESEs were performed with a sperm retrieval rate (SRR) of 30.3%. The successful group had a mean age of 32.7 years and a mean body mass index (BMI) of 26.8 kg/m2. Female partners in the successful group had a mean age of 32.2 years. Twenty percent of female partners had infertility factors, 86.7% had no previous pregnancy and 13.3% had a previous miscarriage. The successful group had 15 live births (50%), while 20% had frozen their sperm. 93.3% achieved live birth from single embryo transfer and currently have unutilised embryos in cryostorage to possibly create siblings in the future. Twenty percent had more than one live birth from a single micro-TESE. Sertoli cell-only syndrome (SCOS) was identified in 57.5% of all cases. This was bilateral in 80% of these cases (four cases only sampled unilaterally due to previous orchidectomies). Of the SCOS group, six men went on to have successful sperm extraction (10%). The presence of previous urologic history/surgery increased the risk of azoospermia by 13%. Conclusion: Men with previous urological conditions have an increased risk of azoospermia. SCOS was identified in 57.5% of cases making it the most common histopathological diagnosis in azoospermic men. Based on our cohort, micro-TESE offers potential sperm retrieval in azoospermic men with SCOS. Successful sperm extraction in patients was associated with 50% live births and appeared to be unaffected by the presence of male/female factors. The number of live births could be higher as 20% had frozen their sperm. Concurrent female issues did not appear to affect successful outcome after micro-TESE, although numbers are small.

Background Surgery is often avoided in the setting of pediatric orbital complications from acute sinusitis unless necessitated by alarming ophthalmological signs. Criteria for surgical intervention are not well-defined. Objective We aim to review our experiences, management practices and patient outcomes over a ten-year period for Chandler III patients. Methods A retrospective review was performed from January 1, 2007 through December 31, 2016 of patients treated for orbital symptoms secondary to acute sinusitis at a free-standing tertiary-care pediatric hospital. Results Of the 186 patients reviewed, 42 Chandler III patients were included. Average age was 82.6 months (SD 50.6) with a slight male predominance (M to F, 1.8 to 1). 27 patients (64.3%) underwent intervention including endoscopic sinus surgery (ESS) with or without orbitotomy. Late surgical intervention (>48hrs from admission) demonstrated significant increase in overall length of stay (LOS) when compared with early surgical intervention and/or medical management (median, 6.9 vs 3.6 vs 3.7 days; p < 0.01). Postoperative LOS was also higher in the late surgery group compared with patients who had surgery within 48 hours of admission, but this did not reach statistical significance [median, 3.8 vs 2.8 days, p= 0.12]. There was no significant difference in overall abscess volume between patients who underwent intervention and those who did not (1019 mm3 vs 805 mm3, p = 0.5), but abscess width ≥ 1.2 cm was associated with higher rates of intervention. An alarming extraocular exam was the most common factor associated with surgical intervention. Conclusion Pediatric subperiosteal orbital abscess may prompt surgical intervention by ESS. An alarming ophthalmologic exam should prompt consideration of early intervention, which may lead to decreased overall and post-operative length of hospital stay.

Older adults have higher sedentary behavior (SB), lower physical activity, and are particularly susceptible to negative impacts from the COVID-19 pandemic and associated public health restrictions. Pandemic impacts to SB and health, particularly via objective assessment, are not well documented in the literature. Here we described differences in SB, physical activity, and blood pressure (BP) for older adults before and during the pandemic. Baseline thigh-worn activPAL accelerometer and BP measurements from 95 participants enrolled in a SB intervention trial pre-pandemic were compared to 60 enrolled post-pandemic. We used linear regression models adjusted for demographic and health factors to estimate differences in sample means of SB measures and BP. The post-COVID sample was older (age 67 vs. 70), more female (60% vs. 72%), and included more individuals of color (21% vs. 32%). In fully adjusted models, systolic BP was statistically significantly higher in the post-COVID group (6.8, 95% CI: [0.3,13.3]). After adjustment, activPAL-measured and self-reported activity were non-significant but trended towards greater total sitting (0.4 hours [−0.3, 1.1]), fewer daily steps (−270 [−1078, 538]), and greater self-reported TV time (0.4 hours, [-0.3, 1.1]) post-COVID. Future analyses are warranted to better quantify these impacts and guide clinical care and future interventions.

Background: Uncontrolled blood pressure (BP) in intracerebral hemorrhage (ICH) survivors is common and associated with adverse clinical outcomes. We investigated whether characteristics of the ICH itself were associated with uncontrolled BP at follow-up. Methods: Subjects were consecutive patients aged ⩾18 years with primary ICH enrolled in the prospective longitudinal ICH study at Massachusetts General Hospital between 1994 and 2015. We assessed the prevalence of uncontrolled BP (mean BP ⩾140/90 mmHg) 6 months after index event. We used multivariable logistic regression models to assess the effect of hematoma location, volume, and event year on uncontrolled BP. Results: Among 1492 survivors, ICH was lobar in 624 (42%), deep in 749 (50%), cerebellar in 119 (8%). Lobar ICH location was associated with increased risk for uncontrolled BP after 6 months (OR 1.35; 95% CI [1.08–1.69]). On average, lobar ICH survivors were treated with fewer antihypertensive drugs compared to the rest of the cohort: 2.1 ± 1.1 vs 2.5 ± 1.2 ( p < 0.001) at baseline and 1.8 ± 1.2 vs. 2.4 ± 1.2 ( p < 0.001) after 6 months follow-up. After adjustment for the number of antihypertensive drugs prescribed, the association of lobar ICH location with risk of uncontrolled BP was eliminated. Conclusions: ICH survivors with lobar hemorrhage were more likely to have uncontrolled BP after 6 months follow-up. This appears to be a result of being prescribed fewer antihypertensive medications. Future treatment strategies should focus on aggressive BP control after ICH independent of hemorrhage location.
Thyroid Rupture Secondary to Blunt Neck Trauma: A Case Report
Authors: Perdon-Chan Liza Rowena D. , Roasa Francis V. 
Published: April 2022

Aim To discuss the clinical presentation of thyroid rupture following blunt neck trauma and highlight key management principles for the case. Methods A 45-year-old female motorcycle passenger with a pre-existing right thyroid nodule hit her right anterior neck against a bottle during sudden stop and developed painful right neck swelling, odynophagia, and hoarseness. She was seen at the emergency room 5 hours post-injury, awake, cooperative, and ambulatory, without stridor or dyspnea at room air. On examination, she had ecchymoses behind her right tonsillar pillars; her neck was grossly swollen and was tender on palpation without subcutaneous emphysema. Laryngoscopy showed good left vocal cord mobility while the right vocal cord had a visible hemorrhage and limited abduction due to the mass effect of the hematoma seen at the right aryepiglottic area extending toward the right piriform fossa and the right parapharyngeal area. Intact bilateral vocal cord adduction was noted upon phonation. Contrast-enhanced computed tomography revealed hematoma formation in the right thyroid lobe area with extension to the right side of the oropharyngeal region, anterior cervical, parapharyngeal, and retropharyngeal space, confirming the aerodigestive tract narrowing and leftward deviation previously noted. Baseline thyroid function tests were normal. Under general anesthesia, the patient underwent neck exploration where the ruptured right thyroid lobe was resected, and the hematoma was evacuated. Results Postoperatively noted significant improvement in neck swelling, odynophagia, and hoarseness. Transient subclinical hyperthyroidism remained asymptomatic and resolved upon outpatient follow-up. A year after the surgery, the patient had a well-healed cervical scar, complete hematoma resolution, and regained her pre-morbid phonation. Conclusion Thyroid gland rupture should be among the considerations for patients presenting with tender neck swelling, progressive hoarseness, and/or dyspnea following neck trauma. Prompt airway assessment and close monitoring for potential compromise are essential to avoid fatal sequelae of external airway compression. Management varies from close observation to surgical neck exploration and should be personalized depending on the severity of thyroid injury and symptomatology.

AbstractSevere chronic neutropenia (SCN), defined as blood neutrophils &lt;0.5 × 109/L for &gt;3 months, is an uncommon hematological condition associated with recurrent and severe bacterial infections. After short-term clinical trials showed the benefits of granulocyte colony-stimulating factor (G-CSF) treatment for SCN, SCNIR (Severe Chronic Neutropenia International Registry) opened to determine the long-term benefits and safety of this treatment. This report summarizes findings from more than 16 000 patient-years of prospective observations for patients with congenital and acquired SCN. We observed that adverse outcomes depend on the underlying etiology. Myelodysplasia (MDS) and acute myeloid leukemia (AML) occur infrequently and largely in patients with congenital neutropenias. Having cyclic or chronic autoimmune/ idiopathic neutropenia portends a favorable prognosis. A few patients with idiopathic neutropenia evolve to develop lymphoid malignancies, but they do not appear to be at increased risk of myeloid malignancies, even with very long-term G-CSF therapy. Progression to systemic autoimmune diseases, bone marrow (BM) failure, aplastic anemia, or nonmyeloid malignancies are not expected consequences of SCN or treatment with G-CSF.

Abstract
Burnout is prevalent throughout medicine. Few large-scale studies have examined the impact of physician compensation or clinical support staff on burnout among hematologists and oncologists. In 2019, the American Society of Hematology conducted a practice survey of hematologists and oncologists in the AMA (American Medical Association) Masterfile; burnout was measured using a validated, single-item burnout instrument from the Physician Work–Life Study, while satisfaction was assessed in several domains using a 5-point Likert scale. The overall survey response rate was 25.2% (n = 631). Of 411 respondents with complete responses in the final analysis, 36.7% (n = 151) were from academic practices and 63.3% (n = 260) from community practices; 29.0% (n = 119) were female. Over one-third (36.5%; n = 150) reported burnout, while 12.0% (n = 50) had a high level of burnout. In weighted multivariate logistic regression models incorporating numerous variables, compensation plans based entirely on relative value unit (RVU) generation were significantly associated with high burnout among academic and community physicians, while the combination of RVU + salary compensation showed no significant association. Female gender was associated with high burnout among academic physicians. High advanced practice provider utilization was inversely associated with high burnout among community physicians. Distinct patterns of career dissatisfaction were observed between academic and community physicians. We propose that the implementation of compensation models not based entirely on clinical productivity increased support for women in academic medicine, and expansion of advanced practice provider support in community practices may address burnout among hematologists and oncologists.
Long-term follow-up of a case of Coats disease in a 10-year-old boy with spontaneous peeling of preretinal macular fibrosis: a case report
Authors: Mizobuchi Tomoka , Nishiuchi Takashi , Miura Yusaku , Fukuda Ken 
Published: April 2022

Abstract
Background
Coats disease is a retinal vascular disorder characterized by aneurysms and telangiectasias. Macular fibrosis is a complication of Coats disease that results in vision loss. Macular fibrosis rarely develops in the natural course and often occurs after treatment with intravitreal bevacizumab, photocoagulation, or cryotherapy. Here, we have described an unusual case of spontaneous peeling of preretinal macular fibrosis in a patient with untreated Coats disease.

Case presentation
A 10-year-old Japanese boy presented with vision loss in his left eye. The patient’s left visual acuity was 20/28. Fundus examination of his left eye revealed thick preretinal macular fibrosis around the optic disc and macula. In addition, retinal telangiectasis, microaneurysms, hard exudates, and retinal hemorrhages were observed in the left peripheral temporal retina. We diagnosed his condition as Coats disease with preretinal macular fibrosis. Two months later, optical coherence tomography revealed preretinal macular fibrosis detachment at the foveal lesion without any treatment. During follow-up, preretinal macular fibrosis at the macular lesion was completely detached. Further, posterior vitreous detachment was observed and the shape of the macula and the patient’s left visual acuity had improved.

Conclusions
In our case, both formation and spontaneous peeling of preretinal macular fibrosis occurred without any treatment for Coats disease, which is an unusual finding. Vitreous changes might have occurred during the natural clinical course, causing subsequent posterior vitreous detachment and resulting in spontaneous peeling of fibrosis.
Preoperative binocular vision characteristics in the age-related cataract population
Authors: Tan Qing-Qing , Lewis James S. , Lan Chang-Jun , Liao Xuan , Tang Xiao-Li , Wang Jingyun , Scheiman Mitchell M. 
Published: April 2022

Abstract
Background
This study is the first part of the “Binocular Vision Anomalies after Cataract Surgery” study that aimed to investigate the impact of cataract surgery on binocular vision status in adults with age-related cataract. This study aimed to investigate the preoperative binocular vision status of participants with age-related cataract.

Methods
Patients who elected to undergo bilateral cataract surgery (≥50 years of age) were recruited. Clinical measures of binocular vision including stereopsis, ocular alignment, fusional vergence, vergence facility, convergence amplitude and a symptom survey related to binocular vision anomalies were administered. A detailed classification protocol was established to identify the presence of binocular vision anomalies. The frequency of specific binocular vision anomalies and normative data of binocular vision measures were reported.

Results
A total of 73 subjects were evaluated. No strabismus was detected in the cohort. Non-strabismic binocular vision anomalies were detected in 24 subjects (32.9%), of whom 18 (24.7%) had convergence insufficiency, 3 (4.1%) had basic exophoria, 2 (2.7%) had convergence excess, and 1 (1.4%) had fusional vergence dysfunction. Decreased vergence facility and convergence amplitude were more common compared to the pre-presbyopes (P < 0.01).

Conclusion
Binocular vision problems, especially convergence insufficiency, are common in the adults with age-related cataract. The study results demonstrate that the lack of normative binocular vision data for the presbyopic population is a significant gap in the literature and suggest the need for a study of normative data for this population.

Trial registration
The study was registered at ClinicalTrials.gov (NCT03592615, USA).

Published: April 2022

Abstract
Background
People who inject drugs (PWID) are vulnerable to SARS-CoV-2 infection. We examined correlates of COVID-19 testing among PWID in the U.S.-Mexico border region and described encounters with services representing potential opportunities (i.e., ‘touchpoints’) where COVID-19 testing could have been offered.

Methods
Between October, 2020 and September, 2021, participants aged ≥18 years from San Diego, California, USA and Tijuana, Baja California, Mexico who injected drugs within the last month completed surveys and SARS-CoV-2, HIV, and HCV serologic testing. Logistic regression identified factors associated with COVID-19 testing including potential touchpoints, comorbidities and COVID-19 related misinformation and disinformation.

Results
Of 583 PWID, 30.5% previously had a COVID-19 test. Of 172 PWID who tested SARS-CoV-2 seropositive (30.1%), 50.3% encountered at least one touchpoint where COVID-19 testing could have been offered within the prior six months. Factors independently associated with at least two fold higher odds of COVID-19 testing were living in San Diego, recent incarceration, receiving substance use treatment, and experiencing ≥1 chronic health condition. Homelessness, having received ≥1 dose of COVID-19 vaccine, and having a HIV or HCV test since the COVID-19 epidemic began were also independently associated with having had a prior COVID-19 test.

Conclusion
We identified several factors independently associated with COVID-19 testing and multiple touchpoints where COVID-19 testing could be scaled up for PWID, such as SUD treatment programs and syringe service programs. Integrated health services are needed to improve access to rapid, free COVID-19 testing in this vulnerable population.
Effect of electrical stimulation on patients with diabetes-related ulcers: a systematic review and meta-analysis
Authors: Zheng Yinhua , Du Xue , Yin Liquan , Liu Hongying 
Published: April 2022

Abstract
Background
This study aimed to systematically review the literature to better understand the efficacy of electrical stimulation (ES) for the treatment of patients with diabetes-related ulcers.

Methods
We searched the Embase, Medline, and Cochrane Library databases through July 31, 2021. Original trials for ES treatment of patients with diabetes-related ulcers with placebo or standard care as the control group were included. The primary outcomes were ulcer area reduction and healing rates. Meta-analyses were performed to compare the standardized mean difference (SMD) in the percentage of ulcer reduction and risk ratio of non-healing rates between ES treatment and placebo or standard care. We used the Revised Cochrane risk-of-bias tool for randomized trials to assess the risk of bias for each included article. Funnel plots and Egger’s test were used to assess publication bias.

Results
Compared to placebo or standard care, ES had a significant benefit for the treatment of patients with diabetes-related ulcers in terms of percentage of ulcer reduction (SMD = 2.56, 95% CI: 1.43–3.69; P < 0.001 (Q-test), I2 = 93.9%) and ulcer healing rates [risk ratio of non-healing rates for the ES group was 0.72 (95% CI: 0.54–0.96; P = 0.38 (Q-test), I2 = 2.3%)]. Two, four, and three of the included studies were categorized into low risk of bias, some concerns, and high risk of bias, respectively. No publication bias was found.

Conclusions
Based on the findings of this meta-analysis, ES could be used to treat patients with diabetes-related ulcers. ES treatment was effective for ulcer area reduction and ulcer healing, although it had a high heterogeneity level among the included studies. Pulsed current ES has the potential benefit of increasing ulcer healing compared to direct current ES. Further large-scale clinical trials are needed to define the adverse events and potentiators of ES in the treatment of patients with diabetes-related ulcers.
