RESUMO

PURPOSE: Men on active surveillance with Grade Group 1 prostate cancer who reclassify to Grade Group 2 on surveillance biopsy often leave active surveillance. We aimed to identify subgroups of men who can safely remain on active surveillance despite preoperative reclassification to Grade Group 2. MATERIALS AND METHODS: We studied 249 active surveillance patients with surveillance biopsies classified as Grade Group 1 or Grade Group 2 who underwent radical prostatectomy. Perineural invasion, cancer volume, linear length and maximum percentage of Gleason pattern 4, and prostate-specific antigen density were evaluated. Radical prostatectomy adverse pathology was defined by any of: pN1; ≥pT3; ≥Grade Group 2 with ≥20% Gleason pattern 4; intraductal carcinoma; large cribriform glands. RESULTS: A multivariable logistic regression model incorporating prostate-specific antigen density and perineural invasion stratified radical prostatectomy adverse pathology risk among Grade Group 1 and Grade Group 2 active surveillance patients. 57% (39/68) of Grade Group 1 men reclassified to Grade Group 2 while on active surveillance had favorable radical prostatectomy pathology. Those without biopsy perineural invasion and with low prostate-specific antigen density were more likely to have favorable radical prostatectomy pathology. CONCLUSIONS: Most Grade Group 1 men who enter active surveillance and subsequently reclassify to Grade Group 2 have favorable findings at radical prostatectomy and can remain on active surveillance. Among patients reclassified to Grade Group 2, those with low prostate-specific antigen density and without perineural invasion had the lowest risk of radical prostatectomy adverse pathology, comparable to (or below) that of Grade Group 1 patients who were not reclassified to Grade Group 2 preoperatively. Prostate-specific antigen density and perineural invasion stratify risk in active surveillance patients reclassified to Grade Group 2 and, if concordant with other clinicopathological and radiographic findings, can enable more patients to remain on active surveillance. Reclassification to Grade Group 2 alone should not disqualify men from remaining on active surveillance.

RESUMO

Nested subtype of urothelial carcinoma (NVUC) of the upper urinary tract is rare. While this subtype has an aggressive behavior in the urinary bladder, little is known about this subtype in the renal pelvis and ureter. In addition, due to NVUC's bland morphology and resemblance to von Brunn nests proliferation, which can be florid in the renal pelvis and ureter, establishing a diagnosis of NVUC in these sites can be difficult, especially on small biopsies. Nineteen cases of NVUC of the renal pelvis and the ureter were identified. One was in-house and 18 cases were sent to the genitourinary pathology consult service. Four cases were excluded due to difficulty in obtaining the slides from other institutions. In all, 8/15 (53.33%) cases showed large nested morphology, 4/15 (26.66%) cases showed mixed large and small nested morphology, and only 3/15 (20%) cases showed predominantly small nested morphology. In all cases, the invasive component was pure nested subtype, and tumors were all unifocal. In 8/15 cases, there was the presence of an overlying low-grade papillary urothelial carcinoma. An associated desmoplastic stromal reaction was none/minimal in 12/15 (80%) cases, with a prominent reaction in the remaining 3/15 (20%) cases. Pathologic stages for the resections were pT1 (n=1), pT2 (n=3), pT3 (n=8), and pT4 (n=1). There was only 1 case with a lymph node metastasis at the time of resection who had pT4 disease. Follow-up was available in 10/15 cases, 7/10 cases showed no recurrences or metastases, and the remaining 3/10 cases later developed urothelial carcinoma of the bladder. In 5/15 cases, follow-up could not be obtained. Similar to NVUC in the urinary bladder, NVUC in the upper tract typically lacks an associated desmoplastic reaction and has by definition bland cytology. In contrast to NVUC of the urinary bladder, NVUC in the upper urothelial tract is: (1) more frequently associated with an overlying papillary urothelial carcinoma; (2) more commonly has a large nested pattern; and (3) appears to behave less aggressively.

RESUMO

Postpartum family planning (FP) could prevent more than 30% of maternal deaths by effectively spacing births; this is particularly relevant in humanitarian contexts given that disproportionate maternal death occurs in countries affected by crises. In humanitarian settings, where accessing functional facilities is challenging with security risks that constrain movement, many women are unable to return for their 6-week postpartum visits and thus unable to receive FP counseling and adopt a method that suits their fertility intentions. Thus, immediate postpartum family planning (IPPFP) interventions, focused on long-acting reversible contraception (LARC) and tailored toward humanitarian contexts, could contribute to healthy timing and spacing of pregnancy, particularly among postpartum women, and improve maternal and newborn health. In 2014, Save the Children integrated postpartum intrauterine device (IUD) services into its FP package in emergency settings. In 2017, this expanded to include postpartum implant uptake as well, given updated World Health Organization guidelines. Three countries (Democratic Republic of Congo, Somalia, and Pakistan) opted for higher-intensity programming for IPPFP with a specific focus on LARC. This involved training delivery-room providers on counseling and provision of IPPFP, as well as training antenatal care nurses in counseling pregnant women on IPPFP options. Three countries (Rwanda, Syria, and Yemen) did not implement notable IPPFP interventions, although they provided the standard of care and monitored provision via monthly service delivery data. Using data from 2016 to 2019, we examined trends in immediate postpartum LARC (IPP LARC) uptake and compared countries with higher-intensity IPP LARC interventions to countries providing standard care. Tests of association were performed to assess the significance of these differences. In the country programs with higher-intensity IPPFP interventions, IPP LARC as a percentage of all deliveries was much higher overall during the July 2016-December 2019 period. The IPP LARC intervention had a significant impact on the overall proportion of women and girls who adopted an IUD or implant within the first 48 h of delivery, F (1, 250) = 523.16, p < 0.001. The mean percentage of IPP LARC among all deliveries in intervention country programs was 10.01% as compared to 0.77% in countries providing standard care. Results suggest that there is demand for IPP LARC in humanitarian contexts and that uptake increases when multipronged solutions focusing on provider training, community outreach, and service integration are applied.

RESUMO

BACKGROUND: More than 2.5 million newborns die each year, accounting for 47% of children dying worldwide before their age of five years. Complications of preterm birth are the leading cause of death among newborns. Pakistan is amongst the top ten countries with highest preterm birth rate per 1000 live births. Globally, Every Newborn Action Plan (ENAP) has emphasized on Kangaroo Mother Care (KMC) as an essential component of neonatal health initiatives. MATERIALS AND METHODS: We conducted this qualitative study with 12 in-depth interviews (IDIs) and 14 focus group discussion (FGD) sessions, in two health facilities of Sindh, Pakistan during October-December 2016, to understand the key barriers and enablers to a mother's ability to practice KMC and the feasibility of implementing and improving these practices. RESULTS: The findings revealed that community stakeholders were generally aware of health issues especially related to maternal and neonatal health. Both the health care providers and managers were supportive of implementing KMC in their respective health facilities as well as for continuous use of KMC at household level. In order to initiate KMC at facility level, study respondents emphasized on ensuring availability of equipment, supplies, water-sanitation facility, modified patient ward (e.g., curtain, separate room) and quality of services as well as training of health providers as critical prerequisites. Also in order to continue practicing KMC at household level, engaging the community and establishing functional referral linkage between community and facilities were focused issues in facility and community level FGDs and IDIs. CONCLUSION: The study participants considered it feasible to initiate KMC practice at health facility and to continue practicing at home after returning from facility. Ensuring facility readiness to initiate KMC, improving capacity of health providers both at facility and community levels, coupled with focusing on community mobilization strategy, targeting specific audiences, may help policy makers and program planners to initiate KMC at health facility and keep KMC practice continued at household level.

RESUMO

BACKGROUND: The Milan System for Reporting Salivary Gland Cytopathology (MSRSGC) is a 6-tier diagnostic category system with associated risks of malignancy (ROMs) and management recommendations. Submandibular gland fine-needle aspiration (FNA) is uncommon with a higher frequency of inflammatory lesions and a higher relative proportion of malignancy, and this may affect the ROM and subsequent management. This study evaluated the application of the MSRSGC and the ROM for each diagnostic category for 734 submandibular gland FNAs. METHODS: Submandibular gland FNA cytology specimens from 15 international institutions (2013-2017) were retrospectively assigned to an MSRSGC diagnostic category as follows: nondiagnostic, nonneoplastic, atypia of undetermined significance (AUS), benign neoplasm, salivary gland neoplasm of uncertain malignant potential (SUMP), suspicious for malignancy (SM), or malignant. A correlation with the available histopathologic follow-up was performed, and the ROM was calculated for each MSRSGC diagnostic category. RESULTS: The case cohort of 734 aspirates was reclassified according to the MSRSGC as follows: nondiagnostic, 21.4% (0%-50%); nonneoplastic, 24.2% (9.1%-53.6%); AUS, 6.7% (0%-14.3%); benign neoplasm, 18.3% (0%-52.5%); SUMP, 12% (0%-37.7%); SM, 3.5% (0%-12.5%); and malignant, 13.9% (2%-31.3%). The histopathologic follow-up was available for 333 cases (45.4%). The ROMs were as follows: nondiagnostic, 10.6%; nonneoplastic, 7.5%; AUS, 27.6%; benign neoplasm, 3.2%; SUMP, 41.9%; SM, 82.3%; and malignant, 93.6%. CONCLUSIONS: This multi-institutional study shows that the ROM of each MSRSGC category for submandibular gland FNA is similar to that reported for parotid gland FNA, although the reported rates for the different MSRSGC categories were variable across institutions. Thus, the MSRSGC can be reliably applied to submandibular gland FNA.

RESUMO

A 41-year-old female patient presented with left-sided flank pain and gross hematuria temporally unrelated to her menstrual cycle. Abdominal computed tomography scan showed a large left-sided solid, enhancing kidney mass radiographically consistent with renal cell carcinoma. Following surgical resection, histopathological examination revealed polypoid endometriosis. Polypoid endometriosis is rare and mimics a neoplasm clinically, radiographically, and on gross examination. Patients with polypoid endometriosis often present with symptoms related to mass effect rather than classic endometriosis hallmark symptoms such as dyspareunia, dysmenorrhea, and cyclic abdominal pain. Treatment includes surgical resection.

RESUMO

OBJECTIVE: We sought to estimate the prevalence of rape-related pregnancy as an indication for abortion at two public Chicago facilities and to describe demographic and clinical correlates of women who terminated rape-related pregnancies. METHODS: We performed a cross-sectional study of women obtaining abortion at the Center for Reproductive Health (CRH) at University of Illinois Health Sciences Center and Reproductive Health Services (RHS) at John H. Stroger, Jr. Hospital between August 2009 and August 2013. Gestational age limits at CRH and RHS were 23+6 and 13+6weeks, respectively. We estimated the prevalence of rape-related pregnancy based on billing code (CRH) or data from an administrative database (RHS), and examined relationships between rape-related pregnancy and demographic and clinical variables. RESULTS: Included were 19,465 visits for abortion. The majority of patients were Black (85.6%). Prevalence of abortion for rape-related pregnancy was 1.9%, and was higher at CRH (6.9%) than RHS (1.5%). Later gestational age was associated with abortion for rape-related pregnancy (median 12days, p<.001). Younger age and Black race were associated with abortion for rape-related pregnancy at CRH only (p<.001 for both). Chlamydia and gonorrhea infection were no more prevalent among women terminating rape-related pregnancy than among those terminating for other indications. CONCLUSION: Rape-related pregnancy as an indication for abortion had a low, but clinically significant prevalence at two urban Chicago family planning centers. Later gestational age was associated with abortion for rape-related pregnancy. IMPLICATIONS: Rape-related pregnancy may occur with higher prevalence among some subgroups of women seeking abortion than others. Efforts to address rape-related pregnancy in the abortion care setting are needed.
