hormone therapy is a medically necessary treatment for many transgender individuals with gender dysphoria, not all transgender patients experience gender dysphoria and not everyone desires hormone treatment. Gender-affirming hormone therapy is not effective contraception. Sexually active individuals with retained gonads who do not wish to become pregnant or cause pregnancy in others should be counseled about the possibility of pregnancy if they are having sexual activity that involves sperm and oocytes. Although being knowledgeable about the medications used for gender transition and potential risks and side effects is important, specific certification for prescribing them is not required and should not be a limiting factor in helping patients access care.
Morcellation is a surgical technique used to reduce the size of the uterus or myomas by creating smaller pieces to allow the tissue to be removed through small incisions or with laparoscopic instruments. Open (uncontained) morcellation of the uterus and myomas has been scrutinized because of the possible spread of an unsuspected leiomyosarcoma while using a power morcellator during a hysterectomy or myomectomy for presumed symptomatic uterine leiomyomas. Before considering morcellation of the uterus, a woman should be evaluated to determine if she is at increased risk of malignancy of the uterine corpus. Morcellation of a malignancy is contraindicated and women should be evaluated preoperatively to identify malignancy. However, leiomyosarcoma cannot be reliably diagnosed preoperatively; thus, there is a risk that a woman with a presumed leiomyoma may have a malignancy that may be spread through morcellation, leading to a potentially worsened prognosis. Although an abdominal hysterectomy or myomectomy may ref malignancy of the uterine corpus. Morcellation of a malignancy is contraindicated and women should be evaluated preoperatively to identify malignancy. However, leiomyosarcoma cannot be reliably diagnosed preoperatively; thus, there is a risk that a woman with a presumed leiomyoma may have a malignancy that may be spread through morcellation, leading to a potentially worsened prognosis. Although an abdominal hysterectomy or myomectomy may reduce the chance of spreading cancer cells in women with undiagnosed leiomyosarcoma, it is associated with increased morbidity when compared with minimally invasive approaches. The obstetrician-gynecologist and patient should engage in shared decision making, including informed consent, explaining the risks and benefits of each approach to surgery for presumed leiomyomas, the risks and benefits of morcellation, and alternatives to morcellation.
To compare operative outcomes of postpartum salpingectomy and tubal ligation after vaginal delivery.

This retrospective cohort study identified patients who underwent tubal sterilization between January 1, 2009, and December 31, 2019, at a large academic hospital, using the electronic medical record. All patients who delivered vaginally and underwent tubal sterilization during their delivery admissions were included. The primary outcome was total operative time. Secondary outcomes included estimated blood loss, perioperative complications, and readmission within 6 weeks postpartum. Patients who underwent bilateral tubal ligation were compared with those who underwent bilateral salpingectomy using Pearson's χ2 test, Fisher exact, and Student's t test.

A total of 317 eligible patients were identified. One hundred and six (94%) salpingectomies were completed using a bipolar electrocautery device. Operative time was 3 minutes shorter in the salpingectomy group, 30 minutes (interquartile range 24-38) compared with 33.5 (26-42) minutes, P=.032. PP2 clinical trial Patients who underwent salpingectomy were more likely to have estimated blood loss of 5 mL or less (our institutional shorthand for minimal blood loss) than women who underwent bilateral tubal ligation (78 [69%] vs 112 [55%], P=.015). There were no significant differences in perioperative complications between the groups.

When using electrocautery, bilateral salpingectomy can be completed in the immediate postpartum period after vaginal delivery with equivalent operative times to bilateral tubal ligation.

We analyzed OS in a nationwide, consecutive cohort diagnosed with metastatic uveal melanoma between January 1999 and December 2016. The Helsinki University Hospital Working Formulation was used to assign patients to stage IVa, IVb and IVc, corresponding to predicted median OS ≥12, less then 12-6 and less then 6 months, respectively. OS of 216 actively treated patients was compared by treatment and working formulation stage against 108 similarly staged, concurrent patients managed with BSC using Kaplan-Meier analysis and Cox regression. The median OS with active treatment was 18 (range, 0.7-162), 6.9 (range, 1.3-30) and 1.9 (range, 0.2-18) months in working formulation stage IVa, IVb and IVc, respectively. Patients who received chemoimmunotherapy, selective internal radiation therapy, or underwent surgical resection survived longer - median OS 13, 16 and 24 months, respectively - than those receiving conventional chemotherapy - median OS 5.1 months - but only with surgical resection their OS exceeded that with BSC, both overall and in stage IVa (P  less then  0.001, P = 0.010). In stage IVb and IVc, no difference in OS was observed in any comparison. Staging of patients is crucial when comparing survival after metastatic uveal melanoma. Only surgical resection for stage IVa disease provided longer OS in our national cohort. We additionally recommend stage-specific comparison of novel treatments against available BSC data.
The atrial septal pouch is an anatomic variant of the interatrial septum caused by incomplete fusion of the septum primum and secundum. It is debatable whether coexistence of septal pouch and atrial fibrillation (AF) increases the risk of stroke. Thus, the aim of the study was to evaluate the coexistence of left atrial septal pouch (LASP) and AF in patients with a history of stroke in comparison with those without an earlier history of stroke.

We analyzed 145 patients with AF (68 in the study group, 77 in the control group). The study group consisted of patients with previous stroke and AF; control group consisted of patients scheduled for AF ablation. All patients underwent computed tomography with the assessment of atrial septum morphology and presence of LASP. The study was a subanalysis of the ASSAM (AssesSment of the left atrial appendage morphoLogy in patients aAfter ischaeMic Stroke) study.

The prevalence of LASP in the entire group was 38.6%. There were no significant differences in the prevalence of LASP between the study and control groups (33.
