Hormone Prescription and HIV Screening/Preventive Practices Among Clinicians Providing Care for Transgender Individuals

Purpose

Through a survey-based approach, we sought to investigate regional differences in gender-affirming hormone therapy (GAHT) prescribing practices, as well as HIV screening and prevention practices among clinicians providing care to transgender individuals.

Methods

Our survey was disseminated between December 2019 and January 2021 to clinicians who prescribe GAHT within New England (United States). Between-group differences in GAHT prescribing and HIV screening/prevention practices were evaluated by practice setting and subspecialty.

Results

Of the 20 survey respondents, 55% practiced in health care settings affiliated with an academic institution, 45% practiced in a community-based health care setting, and 30% were Endocrinologists. Clinicians in community-based health care settings reported more frequently prescribing oral 17β-estradiol (p=0.02) and spironolactone (p=0.007) for feminizing GAHT compared with clinicians in health care settings affiliated with an academic institution, who reported more frequently prescribing leuprolide (p=0.03). For masculinizing GAHT, clinicians from health care settings affiliated with an academic institution reported more frequently prescribing topical testosterone (p=0.03). There were no significant between-group differences in reported barriers to initiation or reasons for stopping GAHT. While non-Endocrinologists reported "often" or "always" offering HIV screening, most Endocrinologists reported "rarely" or "never" offering HIV screening and "rarely" or "never" offering pre-exposure or postexposure prophylaxis to their transgender patients.

Conclusions

Regional GAHT prescribing practices varied by setting. Additional research is needed to better understand whether these differences translate to differences in GAHT efficacy and side-effects. Further, HIV screening/prevention practices varied by subspecialty. Integrated GAHT and HIV screening/prevention across subspecialties could help reduce the disproportionate burden of HIV faced by the transgender community.

Cardiovascular Disease Risk Among Transgender People with HIV

PURPOSE OF REVIEW

Transgender individuals are at disproportionate risk for HIV infection, with prevalence rates highest among transgender women of color. Antiretroviral therapy (ART)-treated people with HIV (PWH) are at increased risk for cardiovascular disease (CVD), in relation to persistent systemic immune activation and metabolic dysregulation. The purpose of this review is to examine parameters which may affect CVD risk among transgender PWH.

RECENT FINDINGS

Among transgender women and men, prospective longitudinal studies have shown that gender-affirming hormonal therapy (GAHT) is associated with select deleterious cardiometabolic effects such as increases in visceral adipose tissue. Retrospective studies among transgender women and men suggest an increase in CVD risk, such as venous thromboembolism, cerebrovascular accidents, and myocardial infarction. Studies among transgender PWH adhering to GAHT and ART suggest heightened systemic immune activation/inflammation. Prospective longitudinal studies assessing factors associated with increased CVD events among transgender PWH are needed to guide the development of CVD prevention strategies in this at-risk population.

Menopausal Symptoms and Cardiovascular Disease Risk Indices Among Women With HIV

Background: Women with HIV (WWH) (vs. women without HIV) have an increased risk of cardiovascular disease (CVD) in relation to heightened systemic immune activation/inflammation. Moreover, WWH show evidence of advanced reproductive aging and unique patterns of hot flash symptomatology. General population studies have revealed that hot flashes may relate to surrogate markers of CVD risk. The relationship between hot flashes and immune activation as well as subclinical cardiac pathology among WWH has not been previously investigated.

Methods: In a prospective, cross-sectional study, 23 WWH on anti-retroviral therapy and 19 women without HIV (ages 40–75), group-matched on age and BMI, were enrolled and completed reproductive health assessments, immune phenotyping and cardiovascular MRI. Women without prior CVD or diabetes were eligible.

Results: Women were similar in age and BMI (WWH vs. women without HIV: 51 ± 5 vs. 52 ± 6 years, P=0.79 and 32 ± 8 vs. 31 ± 7 kg/m2, P=0.71). There was no significant between-group difference in the percentage of women without menses in the past year (p=0.52) or in the percentage of women with undetectable levels of anti-mullerian hormone (p=0.71). No women in either group were on estrogen and/or progesterone for treatment of menopausal symptoms. Hot flash frequency (days per week with hot flashes) was higher among WWH versus women without HIV (median [IQR], 7.0 [1.3, 7.0] vs. 0.8 [0.0, 2.1], p=0.01). In sensitivity analyses excluding either women with menses in the past year or with detectable AMH, WWH still reported a significantly higher number of days per week with hot flashes (7.0 [6.3, 7.0] vs. 0.4 [0.0, 2.3], p=0.007, and 7.0 [2.4, 7.0] vs. 0.8 [0.0, 2.1], p=0.01, respectively). Among WWH experiencing (vs. not experiencing) hot flashes in the past year, longer duration of ART use was noted (21.2 [16.0, 22.7] vs. 9.3 [3.3, 16.0] years, p=0.03). Among the entire cohort and among WWH, women with more than one hot flash per day had higher levels of soluble CD14, a marker of monocyte activation, compared to women with one or fewer hot flash per day (p=0.004 and p=0.02, respectively). Among WWH and a history of hot flashes, years since onset of hot flashes related to cardiovascular MRI-derived measures of subclinical pathology. Specifically, years since onset of hot flashes related directly to myocardial steatosis (intramyocardial triglyceride content; ρ=0.80, p=0.02) and inversely to diastolic function (left atrial passive ejection fraction; ρ=─0.70, p=0.03).

Conclusions: WWH experienced a higher frequency of hot flashes compared to women without HIV. Among WWH, hot flash symptomatology related to systemic immune activation and to cardiovascular MRI-derived measures of CVD risk. Additional research is required to improve understanding of mechanisms underlying these relationships and determine if hot flashes are a sex-specific risk factor for CVD in WWH.

Hot Flashes and Cardiovascular Disease Risk Indices Among Women With HIV

Women with HIV (WWH) transitioning through menopause have heightened cardiovascular disease (CVD) risk. In the general population, hot flash burden relates to CVD risk indices. We found higher hot flash burden among women with vs without HIV. Further, among WWH, hot flash burden related to select CVD risk indices.

Effects of Integrase Inhibitor-Based ART on the NLRP3 Inflammasome Among ART-Naïve People With HIV

The NOD-like receptor protein family pyrin domain containing 3 (NLRP3) inflammasome, activated in the setting of HIV, contributes to pro-atherogenic inflammation. Among antriretroviral therapy–naïve people with HIV (vs controls), levels of caspase-1—a key component of the NLRP3 inflammasome—were significantly increased. Six months of elvitegravir/cobicistat/emtricitabine/tenofovir disoproxil fumarate significantly decreased caspase-1 levels in association with CD4+/CD8+ ratio recovery.

[An analysis of spectrum of allergen sensitization among patients with tree pollen allergy in Beijing]

Objective:To explore the feature of allergic sensitization of tree pollen and the relationship between tree pollen and airborne pollen in Beijing. Method:Two thousand five hundred and twenty-one patients with allergic diseases were enrolled between January to July in 2017 in an allergy department. All patients received SPT of 8 kinds of tree pollen. Result:①The overall tree pollen positive rate of SPT was 49.3% (1 244/2 521). Male had a higher positive rate than female (56.4% vs 45.0%, P<0.01) while child group had a higher positive rate than adult group (55.9% vs 48.6%, P<0.05). The poly sensitization was observed with a rate of 26.3%, take the percentage of 53.3% of the overall positive subjects. ②The highest sensitization rate was found in March (62.2%), followed by May (52.1%), the lowest was January (27.9%). There was a positive correlation between tree pollen sensitization rate and pollen count of each month (r=0.929, P<0.01). ③Cypress had the highest positive rate (34.6%), followed by poplar (21.3%), the lowest was sophora (13.3%). The sensitization rate was positively correlated with pollen count among different tree pollen (r=0.714, P<0.05). Conclusion:The main allergic pollen in Beijing was cypress. The tree pollen sensitization showed a seasonality with the peak in March. The sensitization status was tightly associated with the amount of airborne pollen.

Carcinoid tumour of the kidney in a Chinese woman presenting with loin pain

Renal carcinoid tumours are uncommon. The aetiology is not yet fully understood and there is still no useful diagnostic tool for detecting them. We report our experience managing a Chinese woman with a primary renal carcinoid tumour.

Laparoscopic nephrectomy: an early experience at Queen Mary Hospital

OBJECTIVE

To report our early experience of laparoscopic nephrectomy.

DESIGN

Prospective data collection.

SETTING

Queen Mary Hospital, Hong Kong.

PATIENTS

Transperitoneal laparoscopic nephrectomies were performed on 40 patients between July 1997 and December 2002.

MAIN OUTCOME MEASURES

Demographic and perioperative data including operating time, blood loss, postoperative pain score, analgesic requirement, complications, time to resume oral intake, ambulatory state, and length of hospital stay.

RESULTS

Laparoscopic nephrectomy was performed for 21 solid renal masses, five transitional cell carcinomas, and 14 non-functioning kidneys. Seven (17.5%) patients had previous abdominal surgery. The mean body mass index of the patients was 23.9 kg/m(2) and the mean operating time was 229 minutes. The mean estimated blood loss was 370 mL, and two patients required conversion to open surgery because of intra-operative bleeding. Other complications include diaphragmatic injury, port-site bleeding, chyle leakage, bleeding peptic ulcer, and myocardial ischaemia. The postoperative mean analgesic requirement was 26 mg of morphine sulphate equivalent. The mean time for patients to resume oral diet and full ambulation was 1.3 and 2.8 days, respectively, and the mean length of hospital stay was 6.7 days. The mean diameter of the solid renal tumour was 4.1 cm and the surgical margins of all resected specimen for malignant tumours were negative.

CONCLUSION

Laparoscopic nephrectomy is a safe and efficacious approach for resection of benign non-functioning kidneys and malignant renal tumours.

Clinical and radiographic spectrum of septic pulmonary embolism

AIMS

To review the clinical presentation, radiographic findings, and outcome of therapy in children with septic pulmonary embolism.

METHODS

Retrospective analysis of patients in a tertiary paediatric facility in northern Taiwan.

RESULTS

Ten children were identified with septic pulmonary emboli in a four year retrospective chart review between 1998 and 2001. Seven were immunocompetent, two were premature infants, one had beta thalassemia major. Seven had community acquired staphylococcal infections and bacteraemia, of which six were methicillin resistant Staphylococus aureus (MRSA) isolates. Five had soft tissue infections, two bone infections, one suppurative otitis media, one catheter related infection, and one unknown foci of infection. Multiple and bilateral nodular pulmonary parenchymal lesions were common on plain chest radiographs, but chest computed tomography scans showed the additional findings of a "vessel sign" and central cavitations, confirming the existence of septic pulmonary embolism.

CONCLUSIONS

Community acquired MRSA infections occurred in seven patients with septic pulmonary embolism but without predisposing high risk factors. Critically ill children with skin, soft tissue, or bone infections, when associated with septic pulmonary embolism in an area with a high rate of MRSA, should be empirically treated with glycopeptides (such as vancomycin or teicoplanin) before susceptibility results are known, in order to minimise morbidity and avoid mortality.

Prospective study on ultrasonography plus plain radiography in predicting residual obstruction after extracorporeal shock wave lithotripsy for ureteral stones

OBJECTIVES

To compare ultrasonography (US) and plain radiography with intravenous urography (IVU) in predicting ureteral obstruction after in situ extracorporeal shock wave lithotripsy (ESWL) for ureteral stones.

METHODS

From April 1998 to September 2000, 100 consecutive patients with solitary ureteral stones were treated by primary in situ ESWL. ESWL failures were salvaged by ureteroscopic lithotripsy. Ninety-three patients completed the follow-up assessment. US and IVU were performed when plain radiography showed no residual stone. The occurrence of hydronephrosis on US was compared with IVU, the reference standard for ureteral obstruction.

RESULTS

Of the 93 patients, 72 were men and 21 women (mean age 52 years; mean stone size 11.2 mm). ESWL successfully treated 70 ureteral stones (75%), and the 23 failures were treated by ureteroscopic lithotripsy. Sixty-nine patients without hydronephrosis on US had no ureteral obstruction on IVU. Of the 24 patients who had hydronephrosis on US, 8 had ureteral obstruction on IVU. Of the 85 patients who had no ureteral obstruction on IVU, 69 patients showed no evidence of hydronephrosis on US. However, all patients with ureteral obstruction on IVU demonstrated hydronephrosis on US. The sensitivity, specificity, and positive and negative predictive value concerning sonographic hydronephrosis in the prediction of ureteral obstruction was 100%, 81%, 33%, and 100%, respectively. US alone could not define the cause of ureteral obstruction.

CONCLUSIONS

Plain abdominal radiography plus US is highly sensitive for screening ureteral obstruction after primary in situ ESWL for ureteral calculi. It can save up to 74% of patients from the potential risk of IVU. The detection of the cause of obstruction by IVU is only necessary when sonographic evidence of hydronephrosis is present.

Outpatient ureteroscopy: predictive factors for postoperative events

OBJECTIVES

To identify risk factors that can predict the postoperative events of outpatient ureteroscopy.

METHODS

The data of 329 consecutive patients who underwent outpatient ureteroscopy from January 1996 to July 2000 were analyzed. Patient selection for outpatient surgery was based solely on their general medical status and social factors. Eighty-three percent of the procedures were therapeutic ureteroscopy. The reported postoperative events included sleep disturbances, postoperative pain score, emesis, unplanned admission, and other complications. These were compared with the various patient and operative factors. Multivariate analysis was performed to identify the predictive factors for different postoperative events.

RESULTS

The overall success rate of ureteroscopic access to the pathologic site was 99.7%. Most of the therapeutic ureteroscopy performed was ureteroscopic lithotripsy (93%), with a stone-free rate of 91%. Ninety-seven percent of the operations were completed within 90 minutes, and 98% of patients were fit for discharge within 5 hours. Female patients reported more symptoms on the way home (25.8% versus 16%, P = 0.047) and more postoperative emesis (14.4% versus 2.1%, P <0.001). The postoperative pain score on day 1 was higher if the operation had lasted more than 60 minutes (2.4 versus 1.5, P = 0.002). Patients who received postoperative stenting had a higher postoperative pain score on day 3 (1.1 versus 0.4, P <0.001) and a higher complication rate compared with those who required no postoperative stenting (16.8% versus 4%, P <0.001). No predictive factors for unplanned admission were identified.

CONCLUSIONS

Ureteroscopy can be successfully performed in an outpatient setting. Although the early postoperative pain was associated with nature of the operation (which could not be changed), the subsequent postoperative pain and complications were associated with ureteral stenting, which could be reduced by selective stenting. Unplanned admissions could not be predicted.

Treatment and outcome of congenital diaphragmatic hernia

BACKGROUND AND PURPOSE

Congenital diaphragmatic hernia (CDH) is a challenging condition and is associated with a high mortality rate; optimal therapy remains unclear. This retrospective study describes the clinical characteristics of treatment and outcome in 48 infants with CDH.

METHODS

Twenty-eight male (58%) and 20 female (42%) infants with CDH were treated from 1987 through 1998. The goals of the ventilator strategy were permissive hypercapnea (PaCO2 < or = 55 mm Hg) and avoidance of hyperventilation. Infants were initially ventilated with an intermittent mandatory rate of 40 to 60 per minute, peak inspiratory pressure of 20 to 25 cm H2O, and positive end-expiratory pressure of 5 cm H2O. High-frequency positive pressure ventilation was used if hypoxemia or severe hypercapnea (PaCO2 > 60 mm Hg) occurred. Most infants underwent repair after 3 days of age and only four infants underwent early repair within 24 hours of birth. A prophylactic chest tube was placed in the ipsilateral hemithorax postoperatively in all patients treated before 1996. The severity of respiratory distress was estimated by alveolar-arterial oxygen difference, oxygenation index, and alveolar-arterial ratio.

RESULTS

Forty-six patients presented with Bochdalek CDH, and two with Morgangni CDH. Antenatal diagnosis was made in 10 cases. Respiratory distress was the major manifestation and usually occurred immediately after birth. Six cases were diagnosed several months after birth and presented mainly with gastrointestinal symptoms. Eleven patients died before surgery and 37 patients underwent surgical repair. Two infants died postoperatively because of congestive heart failure and tension pneumothorax, respectively. The overall mortality rate was 27%. The major causes of mortality were severe respiratory failure, persistent pulmonary hypertension, pneumothorax, and associated anomalies.

CONCLUSION

Nearly 75% of patients in this series survived. This suggests that noninvasive respiratory care combined with delayed surgery may be an acceptable strategy for the treatment of CDH, and can be used in most medical institutions without equipment for extracorporeal membrane oxygenation therapy.

Successful treatment of Sjögren's syndrome with cyclophosphamide pulse therapy: report of one case

The treatment of Sjögren's syndrome (SS) is very controversial, though several therapeutic regimens have been proposed. Cyclophosphamide pulse therapy has been widely used in many disease entities. However, reports concerning its clinical application in SS were very rare. We report a 17-year-old girl presenting with lupus nephritis and SS, which was refractory to corticosteroid therapy but successfully treated with cyclophosphamide pulse therapy. The improvement of clinical features was confirmed by Schirmer's test and minor salivary gland biopsy.
