RESUMO
BACKGROUND: Occult pancreaticobiliary reflux (OPBR) has a significant correlation with diseases of the gallbladder and biliary system. This study examined the incidence of OPBR by age in patients with benign gallbladder diseases. METHODS: We assessed 475 patients with benign gallbladder diseases who underwent surgery at Shanghai East Hospital from December 2020 to December 2021. Bile samples collected during surgery were tested for amylase. Patients with bile amylase >110 U/L (n = 64) were classified as the OPBR group; the rest (n = 411) as controls. RESULTS: Of the participants, 375 had gallbladder stone (GS), 170 had gallbladder polyp (GP), and 49 had gallbladder adenomyomatosis (GA). The OPBR group was generally older, with OPBR incidence increasing with age, peaking post-45. Rates by age were: 4.9% (<35), 5.2% (35-44), 20.7% (45-54), 22.5% (55-64) and 17.6% (≥65), mainly in GS patients. ROC analysis for predicting OPBR by age yielded an area under the curve of 0.656, optimal cut-off at 45 years. Logistic regression indicated age > 45, GP, male gender, and BMI ≥ 24 kg*m-2 as independent OPBR predictors in GS patients. Based on these variables, a predictive nomogram was constructed, and its effectiveness was validated using the ROC curve, calibration curve and decision curve analysis (DCA). Further stratification revealed that among GS patients ≤ 45, concurrent GA was an OPBR risk; for > 45, it was GP and male gender. CONCLUSIONS: The incidence of OPBR in GS patients is notably influenced by age, with those over 45, especially males without GP, being at heightened risk.

PURPOSE: To investigate the characteristics and natural history of treatment-naive nonexudative polypoidal choroidal vasculopathy (PCV) and to determine biomarkers predicting exudative conversion. METHODS: Patients diagnosed with nonexudative PCV based on indocyanine green angiography and optical coherence tomography were included. Incidence of exudative conversion in nonexudative PCV patients and cumulative estimates for overall risk were assessed. Indocyanine green angiography and optical coherence tomography imaging-based features were analyzed to identify risk factors for exudative conversion. RESULTS: The study included 42 eyes of 40 patients with nonexudative PCV. The mean follow-up duration was 54.3 ± 35.5 months. Of the 42 eyes with nonexudative PCV, exudative conversion developed in 23 eyes (54.8%) after 42.2 ± 28.3 months (range, 8-103 months). Kaplan-Meier analysis showed that the exudation-free survival at 5 years after baseline was estimated to be 53.6%. Multivariate regression analysis showed that sequentially increased protrusion of retinal pigment epithelium in the polyp area was a significant risk factor for exudation in nonexudative PCV (odds ratio = 10.16; 95% CI 1.78-57.81; P = 0.01). CONCLUSION: Exudative conversion has been noted in nearly half of the nonexudative PCV cases in 5 years. The progressive protrusion of polypoidal lesions on optical coherence tomography examination may be a significant biomarker for predicting the near-term onset of exudation.

BACKGROUND AND AIM: We aimed to determine the risk and predictors of gallbladder cancer in all individuals with gallbladder polyps (GP) including those who did not have cholecystectomy. METHODS: The STROCSS guideline was followed to conduct a retrospective cohort study. All individuals with GP between 2010 and 2019 were followed up to determine the risk and predictors of gallbladder cancer. The primary outcomes were gallbladder cancer and gallbladder dysplasia, and the secondary outcomes included polyp growth rate and polyp disappearance rate. Binary logistic regression analysis and receiver operating characteristic curve analysis were conducted to evaluate the outcomes. RESULTS: Analysis of 438 patients showed risk of gallbladder cancer was 0.7% in all polyps (0% in polyps < 10 mm; 5.9% in polyps ≥ 10 mm). The risk of gallbladder dysplasia or cancer was 1.1% in all polyps (0% in polyps < 10 mm; 10% in polyps ≥ 10 mm). The polyp size (P = 0.0001) was predictor of cancer; however, patient's age (P = 0.1085), number of polyps (P = 0.9983), symptomatic polyps (P = 0.3267), and change in size (P = 0.9012) were not. Size of 21 mm was cut-off for risk of cancer (area under the curve [AUC]: 0.995, P < 0.001) and 11.8 mm for risk of dysplasia or cancer (AUC: 0.986, P < 0.001). The mean polyp growth rate was 0.3 mm/year and polyp disappearance rate was 16%. CONCLUSIONS: The GP size remains the only predictor of malignant changes regardless of patient's age, patient's symptoms and number of polyps. The polyp growth rate is unremarkable, and a significant proportion disappears during follow-up. We changed our follow-up protocol with reduced number of scans and early discharge policy.

BACKGROUND: The likelihood of recurrence of gastric hyperplastic polyps (GHPs) following endoscopic resection and the need for long-term follow-up remain unknown. We, therefore, aimed to investigate the factors associated with the recurrence and cumulative incidence of GHPs over a 10-year period. METHODS: Between May 1995 and December 2020, 1,018 GHPs > 1 cm were endoscopically resected from 869 patients. Medical records of these patients were retrospectively reviewed and their clinical features and outcomes were assessed. Groups of GHPs with recurrence and those without recurrence group were compared, and univariate and multivariable analyses were performed to identify the potential risk factors for GHP recurrence. RESULTS: A total of 104 (12.0%) patients who underwent endoscopic removal of GHPs experienced recurrence. Compared to patients without recurrent GHPs, those with recurrent GHPs showed considerably larger median polyp size (28 mm vs. 14 mm, P < 0.001), a higher proportion of multiple polyps (41.3% vs. 29.3%, P = 0.020), polyps with lobulation (63.5% vs. 40.3%, P = 0.001), and exudate (63.5% vs. 46.8%, P = 0.001). Compared to the local recurrence (n = 52) group, the metachronous recurrence (n = 52) group had larger median polyp size (20 mm vs. 16 mm, P = 0.006) as well as higher rates of polyp lobulation (86.5% vs. 40.4%, P < 0.001) and exudate (82.7% vs. 44.4%, P = 0.001). After primary GHP excision, the cumulative incidence of recurrence was 7.2%, 12.7%, and 19.6% at 2 years, 5 years, and 10 years, respectively. CONCLUSION: The incidence of GHP recurrence following endoscopic excision increased as the follow-up period increased, especially in patients whose GHPs were large-sized, multiple, or characterized by surface exudates/lobulations.

BACKGROUND: Polycystic ovary syndrome (PCOS) is characterized by anovulation, insufficient progesterone, hyperandrogenism, and insulin resistance. These factors can disrupt the endometrium of PCOS patients and can lead to chronic low-grade inflammation in the endometrium, endometrial hyperplasia, or even endometrial cancer. OBJECTIVE: The aim of this study was to investigate the prevalence of premalignant and malignant endometrial polyps in premenopausal women and to further explore whether PCOS is associated with premalignant and malignant changes in endometrial polyps. METHODS: This study was conducted by retrieving the medical data of 4236 premenopausal women who underwent hysteroscopic polypectomies between January 2015 and December 2021. Demographic and clinical data regarding age, height, weight, parity, hormone replacement therapy, oral contraceptives, abnormal uterine bleeding, hypertension, diabetes mellitus, PCOS, number of polyps, and size of polyps were collected, and their associations with premalignant and malignant changes in endometrial polyps were analysed. RESULT: Among the endometrial polyps removed by hysteroscopic polypectomy in premenopausal women, the prevalence of premalignant and malignant polyps was 2.15%, which comprised hyperplasia with atypia at 1.13% and endometrial carcinoma at 1.02%. PCOS was associated with a higher risk of premalignant and malignant endometrial polyps in premenopausal women after adjustment for potential confounding factors. CONCLUSION: PCOS is associated with a higher risk of premalignant and malignant endometrial polyps in premenopausal women. Therefore, it is important to evaluate the endometrium in PCOS patients with ultrasonography or hysteroscopy, and active management involving hysteroscopic polypectomy should be offered to PCOS patients diagnosed with endometrial polyps regardless of symptoms.

AIMS: Previous studies have shown an association between chronic endometritis and endometrial polyps, and only one study in infertile women reported an association between tubal obstruction and polyps. This study aimed to compare the prevalence of endometrial polyps in two groups of women with tubal factor infertility and male factor infertility to assess if is there any association between tubal factor infertility and endometrial polyps. METHODS: This case-control study was performed on infertile women. The case group included women with tubal factor infertility and the control group included all women with male factor infertility. In all patients, vaginal ultrasound was performed between days 8 and 12 of the menstrual cycle to diagnose endometrial polyp, its size, and number. Demographic and obstetrics variables were recorded. Patients underwent hysteroscopy and polypectomy and the diagnosis of the polyp was confirmed by pathology report. RESULT: In the present study, 245 people participated in two groups. There was a statistically significant difference between the two groups in terms of demographic and obstetric characteristics like type of infertility, duration of infertility, and gravidity. The prevalence of polyps in the tubal factor group was higher than in the male factor group (63 [60%] vs. 12 [9.8%]), and this difference was statistically significant (p = 0.0001). In addition, the prevalence of chronic endometritis in the tubal factor group was higher than in the male factor group (19 [18.8%] vs. 4 [3.3%]), and this difference was statistically significant (p = 0.001). CONCLUSIONS: In the present study, a strong association was observed between endometrial polyps and tubal obstruction, and considering that the most common cause of tubal obstruction is pelvic and genital infections, after confirmation with more studies, it may be possible to consider antibiotic treatment in these patients, especially in patients with recurrent polyps.

OBJECTIVES: Portal hypertensive polyps (PHPs) are incompletely characterized lesions that can be found in the distal stomach of patients with portal hypertension. We aimed to delineate clinical factors associated with the appearance of these rare polyps. MATERIAL AND METHODS: We conducted a cross-sectional study of a cohort with 513 cirrhotic patients comparing patients with and without PHP using descriptive analyses and multivariable logistic regression. To address the problem of missing values, in particular for HVPG and liver stiffness, we used multiple imputation of missing values. RESULTS: The prevalence of macroscopically diagnosed PHP was 3.3% (95% confidence interval 2.0 - 5.4%). In 53% of cases, the correct classification was missed on index gastroscopy. Patients with PHP were older at gastroscopy (65 years vs. 59), had higher hepatic venous pressure gradients (HVPG, 28 mmHg vs. 19 mmHg), higher transient elastography (TE) measurements (50.7 kPa vs. 21.8 kPa) and more often had previous rubber band ligations (RBL, 64.7% vs. 25.8%). The multivariable logistic regression on the outcome macroscopically diagnosed PHP estimated an odds ratio (OR) for HPVG of 1.13 (CI 0.95-1.34), increased liver stiffness of 1.03 (1.00 - 1.07) and previous RBL of 3.84 (1.24 - 11.88), respectively. CONCLUSION: The prevalence of PHPs in the stomach was higher than assumed in previous studies and misclassification was commonly observed. The appearance of these rare polyps is associated with previous RBL and may correlate with severity of PH. Thus, PHPs may be regarded as marker for relevant PH, but clinical significance of these polyps is still uncertain.

Gall bladder polyp is a lesion which is often an incidentally reported finding on ultrasonography. Such patients may or may not have symptoms of gall bladder disease. Although majority of polyps are cholesterol polyps, some are malignant. The challenge is early detection of malignant polyp and cholecystectomy before it becomes invasive or if invasive to carry out adequately wide surgical excision; while avoiding surgery in asymptomatic patients with benign disease. Following are the characteristics suggestive of malignancy in polyp: - size more than 10 mm, solitary lesions, increase in size over time, adenomatous polyps, sessile lesions and associated gallbladder wall thickening. Incidence of malignancy is higher in patients with Indian ethnicity, age more than 50 years, associated primary sclerosing cholangitis or gall stone disease. Pre-operative tissue diagnosis is difficult to obtain and review ultrasonography, contrast enhanced CT scan, endo sonography and a regular follow-up can help the surgeon take the appropriate decision.

BACKGROUND: The risk of neoplasia in gallbladder polyps seems to be low, but the evidence from populations at high-risk of gallbladder cancer is limited. We aimed to estimate the risk and to identify the factors associated with neoplastic polyps in a high-risk Hispanic population. METHODS: A retrospective cohort was recruited between January 2010 and December 2019 at a Chilean university center. Multivariate survival analyses were conducted. Fine-Gray models were fitted to account for competing risks. Covariate adjustment was conducted using propensity scores. The main outcome was the development of gallbladder adenomas or adenocarcinoma. RESULTS: Overall, 748 patients were included, 59.6% underwent cholecystectomy. The median follow-up of patients not subjected to cholecystectomy was 54.7 months (12-128.6 months). Seventeen patients (2.27%) developed the outcome. After adjustment by age, sex, intralesional blood flow, lithiasis and gallbladder wall thickening, only polyp size (≥10 mm, adjusted-HR: 15.01, 95%CI: 5.4-48.2) and number of polyps (≥3 polyps, adjusted-HR: 0.11, 95%CI: 0.01-0.55) were associated with neoplasia. CONCLUSION: In a Hispanic population at high-risk for gallbladder cancer, gallbladder polyps seem to have a low risk of neoplasia. Polyp size was the main risk factor, while having multiple polyps was associated with an underlying benign condition.

BACKGROUND: Aural polyps consider as one of the most notable progressive lesions of middle ear. Chronic otitis media can result in development of aural polyps that ascends from the tympanic cavity outwards to the external auditory canal, leading to tympanic membrane perforation and hearing loss. Morbidity and mortality are usually rare, however, failure of diagnosis or prolonged negligence by the patient could increase the likelihood of cholesteatoma or malignant squamous carcinoma. AIM: To investigate the causes of middle ear aural polyps in adult patients selected from Kut and Diwaniyah cities in Iraq. METHODOLOGY: 40 patients which of those 14 males and 26 females were included in this study based upon the clinical manifestation of the illness and the suffering from a mass in the tympanic cavity, partial or complete hearing loss, otorrhea and dizziness. Otoscope was used to confirm location, shape, size of the polyps, and the status of the tympanic membrane. RESULTS: The mean age of the involved patients in the study was (44.65 ± 10.9) years. Age range was between (20-60) years. The highest frequency of patients with aural polyps was seen in patients at their third to fifth decade of age. There were 14(35%) men, and 26(65%) women. Findings showed that mean age of men was (44.07 ± 13.7) years, and women was (44.96 ± 9.4) years, (p=0.405). Clinical examination revealed 27(67.5%) patients with cholesteatoma, 10(25%) with inflamed mass in the middle ear, and 3(7.5%) were with cancerous tumor. Correlative analysis showed no significant correlation between age and causes of aural polyps (p=0.664), and no correlation between sex and causes of aural polyps (p=0.524). CONCLUSION: Aural polyps are rare disease in Iraqi patients. However, treating and monitoring patients with ongoing chronic otitis media is essential in preventing the development of aural masses in middle ear and other complications if left untreated. Early diagnosis and treatment can prevent reoccurrence and other complications.

GOALS: Assess neoplasia and polypectomy-related adverse event (AE) rates in gastric hyperplastic polyps (GHPs). BACKGROUND: GHPs carry a risk of neoplastic transformation. The rate of neoplastic transformation and the risk of polypectomy-related bleeding are unclear in the West, as data are derived from Asian or small studies. The authors aimed to determine the rate of dysplasia and intraprocedural AEs in GHP polypectomies in a western cohort. STUDY: A retrospective study of 591 GHPs >1 cm resected in 491 patients in a single referral center on the occurrence of neoplasia and intraprocedural AEs. RESULTS: The mean age was 74.9±11.1 years, 57% female individuals. The mean polyp size was 2±0.8 cm. There were 11 neoplastic polyps (1.9%) with low-grade dysplasia, high-grade dysplasia, and cancer in 7 (1.3%), 2 (0.3%), and 2 (0.3%), respectively. Neoplasia was associated with age [9 (3.2%) for more than 75 years vs. 2 (0.7%) for less than 75 years; P=0.035], but not with polyp size or gender. Fifty patients (8.5%) had intraprocedural bleeding (IPB) requiring endoscopic intervention, with 3 hospitalizations. There were no perforations or procedure-related deaths. IPB was associated with polyp size and neoplasia. The adjusted odds ratio (95% confidence interval) for IPB was 1.63 (1.2-2.2) for a 1 cm increase in polyp size, and 7.4 (1.9-29.6) for the presence of neoplasia. CONCLUSIONS: The neoplasia rate in GHPs was 1.9%, lower than most previous reports, with no major intraprocedural AEs. Physicians may consider biopsy and follow-up in frail elderly patients, but the safety of this strategy needs further confirmation.

PURPOSE: Current international guidelines recommend colonoscopy in patients with acromegaly at the time of diagnosis, even though the risk of developing colorectal neoplasm is still controversial. The main objective of this Argentine multicenter study was to analyze through screening colonoscopy the presence of advanced neoplastic lesions considered as precancerous, in patients with acromegaly compared to a control group. METHODS: This is a case-control retrospective study. Full length colonoscopy of 70 acromegalic patients and 128 control subjects were studied. Polyps were classified into non pre-cancerous lesions and advance neoplastic lesions which included advanced adenomas (preneoplastic) and colorectal carcinomas. RESULTS: Thirty three out of 70 acromegalic patients and 32 out of 128 subjects controls presented polyps in the colonoscopy [47.1% vs 25%, p = 0.002, OR 2.68]. Non precancerous polyps were found in 11 (15.7%) and 23 (17.9%) (p = 0.690), while advanced neoplastic lesions were found in 22 (31.4%) and 9 (7.0%) (p = 0,0001 - OR: 6.06) patients and controls respectively. Advanced adenomas and colorectal carcinomas were found in 18 (27.3%) and 9 (7.0%) (p = 0,0006-OR: 4,57), and 4 (5.7%) and 0 (0.0%) p = 0.0063) of patients and controls respectively. The presence of insulin resistance was the only statistically significant associated factor among acromegalic patients with and without colonic polyps. CONCLUSIONS: Our findings show an increased risk of preneoplastic colonic lesions and colorectal carcinoma in patients with chronic and sustained GH excess compared to a control group. This supports the recommendation to perform screening colonoscopy at diagnosis of acromegaly.

AIM: To determine whether single endometrial polyp (EP) or multiple EP (polyp number ≥ 6) are associated with chronic endometritis (CE). METHODS: From June 2017 to December 2018, this study enrolled a total of 277 patients, including 92 patients with multiple EP, 82 patients with a single EP and 103 patients without polyps who underwent hysteroscopic examination and polypectomy. Polyps and endometrium samples were obtained and subjected to immunohistochemistry for CD138 to identify plasma cells and CE was diagnosed as CD138-positive plasma cells greater than or equal to 5/high power field. The prevalence of CE was compared and analyzed using the logistic regression model. RESULTS: All baseline parameters were comparable among the three groups except that the prevalence of abnormal uterine bleeding (AUB) was much higher in both polyp groups than the non-polyp control. The prevalence of CE was significantly higher in the multiple EP group than in the single EP group (58.7% vs 28.0%, P < 0.001). There was no difference on the prevalence of CE between the single EP and the non-polyp groups (28.0% vs 29.1%, P = 0.872). Multivariable analysis revealed that AUB (adjusted OR 2.81, 95% CI 1.35-5.87) and multiple EP (adjusted OR 2.58, 95% CI 1.38-4.82) were independently associated with CE, while the single EP did not increase the odds of CE compared to the non-polyp group (adjusted OR 0.74, 95% CI 0.38-1.45). CONCLUSION: Multiple EP were positively associated with CE among reproductive-aged women, suggesting a possible hidden etiopathogenetic link between chronic inflammation and multiple EP.

PURPOSE: This study evaluated the factors associated with endometrial pathologies during tamoxifen use in women with breast cancer. METHODS: This study analyzed 821 endometrial biopsies from women who received tamoxifen for breast cancer. Clinical characteristics were compared according to the presence of endometrial pathology (atypical hyperplasia and cancer). In addition, patients with endometrial polyps were compared with women with normal histology. RESULTS: Among 821 biopsies, atypical endometrial hyperplasia and cancer were diagnosed in 7 women each. Endometrial polyps were found in 173 women, and 634 women presented normal histology. In comparing women with endometrial pathology (atypical hyperplasia and cancer, n = 14) and those without pathology, parity was significantly lower (P = 0.014) and endometrial thickness was significantly higher (P < 0.001) in women with pathology. In addition, abnormal uterine bleeding was more common in the pathology group (P < 0.001). However, age, body mass index, menopausal status, intrauterine device use, history of diabetes mellitus, and duration of tamoxifen use did not differ according to the presence of pathology. In comparing women with endometrial polyps and those with normal endometrium, significant differences were found in parity (P < 0.001), duration of tamoxifen use (P = 0.003), and endometrial thickness (P < 0.001), but not in the presence of abnormal vaginal bleeding. CONCLUSION: Parity, endometrial thickness, and the presence of abnormal vaginal bleeding, but not age, body mass index, and menopausal status, may be associated with endometrial pathology during tamoxifen use in women with breast cancer. This finding might provide useful information for gynecological surveillance and counseling during tamoxifen treatment.

BACKGROUND: Gallbladder cancer is rare but associated with significant morbidity and mortality necessitating the early identification of premalignant and malignant lesions to improve overall prognosis. Despite limited evidence regarding the effectiveness of transabdominal ultrasound (US) in the detection of gallbladder polyps, it plays a key role in current European guidelines. The aim of this study was to investigate gallbladder polyp prevalence in a western European population and assess the diagnostic accuracy of transabdominal US. METHODS: Data from patients who underwent cholecystectomy for US detected gallbladder polypoid lesions at four hospitals in Ireland and the United Kingdom between 2010 and 2018 were retrospectively collected. Patient demographics, ultrasonographic, and histopathologic findings were analyzed. RESULTS: A total of 134 patients underwent cholecystectomy for US-detected gallbladder polyps. After histopathologic examination, pseudopolyps were found in 75 (56%) specimens with dysplastic or malignant polyps seen in only six (4.5%) specimens. Mean size for neoplastic polyps was 33 mm. The positive predictive value for US in detecting neoplastic polyps in this study was 4.5%, which is significantly lower than the 10%-15% reported previously. CONCLUSIONS: Although the prevalence of neoplastic polyps in this study is higher than in the previous literature, the distribution of pseudopolyps and true polyps is as expected. With all malignant polyps being >10 mm in diameter, these findings support the current size thresholds stated in European guidelines. The poor diagnostic accuracy of US demonstrated may have led to significant number of patients undergoing unnecessary surgical intervention, further supporting the argument for improved strategies for the investigation of gallbladder polyps.

BACKGROUND: Adjuvant tamoxifen reduces the risk of breast cancer recurrence in women with oestrogen receptor-positive breast cancer. Tamoxifen also increases the risk of postmenopausal bleeding, endometrial polyps, hyperplasia, and endometrial cancer. The levonorgestrel-releasing intrauterine system (LNG-IUS) causes profound endometrial suppression. This systematic review considered the evidence that the LNG-IUS prevents the development of endometrial pathology in women taking tamoxifen as adjuvant endocrine therapy for breast cancer. OBJECTIVES: To determine the effectiveness and safety of the levonorgestrel intrauterine system (LNG-IUS) in pre- and postmenopausal women taking adjuvant tamoxifen following breast cancer for the outcomes of endometrial and uterine pathology including abnormal vaginal bleeding or spotting, and secondary breast cancer events. SEARCH METHODS: We searched the following databases on 29 June 2020; The Cochrane Gynaecology and Fertility Group specialised register, Cochrane Central Register of Controlled Trials, MEDLINE, Embase, PsycINFO and Cumulative Index to Nursing and Allied Health Literature. We searched the Cochrane Breast Cancer Group specialised register on 4 March 2020. We also searched two trials registers, checked references for relevant trials and contacted study authors and experts in the field to identify additional studies. SELECTION CRITERIA: We included randomised controlled trials (RCTs) of women with breast cancer on adjuvant tamoxifen that compared the effectiveness of the LNG-IUS with endometrial surveillance versus endometrial surveillance alone on the incidence of endometrial pathology. DATA COLLECTION AND ANALYSIS: We used standard methodological procedures recommended by Cochrane. The primary outcome measure was endometrial pathology (including polyps, endometrial hyperplasia, or endometrial cancer), diagnosed at hysteroscopy or endometrial biopsy. Secondary outcome measures included fibroids, abnormal vaginal bleeding or spotting, breast cancer recurrence, and breast cancer-related deaths. We rated the overall certainty of evidence using GRADE methods. MAIN RESULTS: We included four RCTs (543 women analysed) in this review. We judged the certainty of the evidence to be moderate for all of the outcomes, due to imprecision (i.e. limited sample sizes and low event rates). In the included studies, the active treatment arm was the 20 µg/day LNG-IUS plus endometrial surveillance; the control arm was endometrial surveillance alone. In tamoxifen users, the LNG-IUS probably reduces the incidence of endometrial polyps compared to the control group over both a 12-month period (Peto odds ratio (OR) 0.22, 95% confidence interval (CI) 0.08 to 0.64, I² = 0%; 2 RCTs, n = 212; moderate-certainty evidence) and over a long-term follow-up period (24 to 60 months) (Peto OR 0.22, 95% CI 0.13 to 0.39; I² = 0%; 4 RCTs, n = 417; moderate-certainty evidence). For long-term follow-up, this suggests that if the incidence of endometrial polyps following endometrial surveillance alone is assumed to be 23.5%, the incidence following LNG-IUS with endometrial surveillance would be between 3.8% and 10.7%. The LNG-IUS probably slightly reduces the incidence of endometrial hyperplasia compared with controls over a long-term follow-up period (24 to 60 months) (Peto OR 0.13, 95% CI 0.03 to 0.67; I² = 0%; 4 RCTs, n = 417; moderate-certainty evidence). This suggests that if the chance of endometrial hyperplasia following endometrial surveillance alone is assumed to be 2.8%, the chance following LNG-IUS with endometrial surveillance would be between 0.1% and 1.9%. However, it should be noted that there were only six cases of endometrial hyperplasia. There was insufficient evidence to reach a conclusion regarding the incidence of endometrial cancer in tamoxifen users, as no studies reported cases of endometrial cancer. At 12 months of follow-up, the LNG-IUS probably increases abnormal vaginal bleeding or spotting compared to the control group (Peto OR 7.26, 95% CI 3.37 to 15.66; I² = 0%; 3 RCTs, n = 376; moderate-certainty evidence). This suggests that if the chance of abnormal vaginal bleeding or spotting following endometrial surveillance alone is assumed to be 1.7%, the chance following LNG-IUS with endometrial surveillance would be between 5.6% and 21.5%. By 24 months of follow-up, abnormal vaginal bleeding or spotting occurs less frequently than at 12 months of follow-up, but is still more common in the LNG-IUS group than the control group (Peto OR 2.72, 95% CI 1.04 to 7.10; I² = 0%; 2 RCTs, n = 233; moderate-certainty evidence). This suggests that if the chance of abnormal vaginal bleeding or spotting following endometrial surveillance alone is assumed to be 4.2%, the chance following LNG-IUS with endometrial surveillance would be between 4.4% and 23.9%. By 60 months of follow-up, there were no cases of abnormal vaginal bleeding or spotting in either group. The numbers of events for the following outcomes were low: fibroids (n = 13), breast cancer recurrence (n = 18), and breast cancer-related deaths (n = 16). As a result, there is probably little or no difference in these outcomes between the LNG-IUS treatment group and the control group. AUTHORS' CONCLUSIONS: The LNG-IUS probably slightly reduces the incidence of benign endometrial polyps and endometrial hyperplasia in women with breast cancer taking tamoxifen. At 12 and 24 months of follow-up, the LNG-IUS probably increases abnormal vaginal bleeding or spotting among women in the treatment group compared to those in the control. Data were lacking on whether the LNG-IUS prevents endometrial cancer in these women. There is no clear evidence from the available RCTs that the LNG-IUS affects the risk of breast cancer recurrence or breast cancer-related deaths. Larger studies are necessary to assess the effects of the LNG-IUS on the incidence of endometrial cancer, and to determine whether the LNG-IUS might have an impact on the risk of secondary breast cancer events.

BACKGROUND: Dyslipidaemia and male sex are associated with gallbladder polyp (GBP) formation. However, the potential relation between the non-high-density lipoprotein-cholesterol-to-high-density lipoprotein-cholesterol (non-HDL-c/HDL-c) ratio and GBPs in men is unclear. METHODS: A total of 1866 eligible subjects were selected for this retrospective cohort study from Wuhan Union Hospital between April 1, 2013, and November 30, 2014. Clinical and laboratory data of subjects were collected. Patients with GBPs or cholecystectomy at baseline, with missing data for baseline lipid profiles, following abdominal ultrasonography or taking lipid-lowering drugs were excluded. The patients were divided into five groups based on their non-HDL-c/HDL-c ratios, and descriptive analyses of the baseline data were performed. A Cox proportional hazards model was applied to estimate the relationship between the non-HDL-c/HDL-c ratio and GBPs. RESULTS: After a median follow-up of 1 year, 7.34% (n = 137) of the subjects developed GBPs. Compared with subjects without GBPs, those who developed GBPs after follow-up had significantly higher triglyceride (TG) levels and non-HDL-c/HDL-c ratios. The prevalence of GBPs showed a linearity increment with age, peaked in the 30-39 years group, 40-49 years group and 50-59 years group, and then declined slightly. The results of univariate analysis showed that the non-HDL-c/HDL-c ratio (hazard ratio (HR) = 1.29, 95% confidence interval (CI), 1.05-1.60, P = 0.0159) was positively correlated with GBPs. In the fully adjusted Cox regression model, the HRs were 2.24 for quintile 2 (95% CI: 1.13-4.44, P = 0.0203), 1.50 for quintile 3 (95% CI: 0.73-3.10, P = 0.269), 2.52 for quintile 4 (95% CI: 1.26-5.01, P = 0.0087) and 2.13 for quintile 5 (95% CI: 1.04-4.37, P = 0.0397). No interaction was found among the subgroups. CONCLUSIONS: A higher non-HDL-c/HDL-c ratio is independently related to a higher risk of GBP formation in Chinese men. Further research is needed to investigate whether this association exists in different regions and races.

STUDY OBJECTIVE: To evaluate the prevalence of chronic endometritis (CE) among fertile and infertile women who underwent hysteroscopic polypectomy. DESIGN: A retrospective cohort study. SETTING: University-affiliated tertiary hospital. PATIENTS: A total of 277 women who underwent hysteroscopic polypectomy in the period from 2015 to 2018. INTERVENTIONS: Endometrial polyp samples were obtained after hysteroscopy for histopathologic analysis using hematoxylin-eosin and immunohistochemistry staining with CD138 antibodies for plasma cell detection. All infertile women diagnosed with CE were treated with oral doxycycline 100 mg twice daily for 14 days before infertility treatment. MEASUREMENTS AND MAIN RESULTS: The prevalence of CE in infertile women (nâ¯=â¯137) was significantly higher than in those with no history of infertility (nâ¯=â¯140) (22.6% vs 8.6%; pâ¯=â¯.001). The prevalence of CE between women with primary infertility and those with secondary infertility was similar (25.0% vs 19.3%; pâ¯=â¯.43). Clinical pregnancy (32.3% vs 41.5%; pâ¯=â¯.35), live birth (29.0% vs 38.7%; pâ¯=â¯.33), and miscarriage (10.0% vs 6.8%; pâ¯=â¯.73) rates were similar between infertile women with treated CE and those without CE. A multivariate model showed that diagnosis of infertility was significantly associated with the diagnosis of CE (odds ratio, 3.16; 95% confidence interval, 1.53-6.49). CONCLUSION: In women with endometrial polyps, the prevalence of CE in infertile women is higher than that in fertile women. Pregnancy outcome in infertile women with treated CE was similar to those who were infertile and without CE.

STUDY OBJECTIVE: The primary aim of our study was to investigate the incidence of endometrial pathologies, especially endometrial cancer, in women with breast cancer treated with tamoxifen (TAM), aromatase inhibitors (AIs), or receiving no treatment (NT). The secondary aim was to identify, in this cohort, ultrasonographic findings that represent robust indications for hysteroscopy and endometrial biopsy, to avoid unnecessary second-level diagnostic procedures. DESIGN: Multicenter retrospective cohort study (Clinical Trial ID: NCT03898947). SETTING: Data were collected from different Italian centers: Regina Elena National Cancer Institute of Rome, Arbor Vitae Centre of Rome, Gaetano Martino University Hospital of Messina, and Villa Sofia-Cervello Hospital of Palermo. PATIENTS: We selected and consecutively included patients with a history of breast cancer who had undergone hysteroscopy for ultrasonographic or clinical indications between January 2007 and December 2016. INTERVENTIONS: Diagnostic hysteroscopy with endometrial biopsy or operative hysteroscopy, when clinically indicated. MEASUREMENTS AND MAIN RESULTS: A higher percentage of patients in the TAM and AI groups had a normal endometrium compared with those in the NT group, whereas the incidence of endometrial polyps was higher in the NT group than in the others; no significant differences were observed among the 3 groups for other benign conditions or for premalignant and malignant uterine diseases, such as endometrial atypical hyperplasia and adenocarcinoma. CONCLUSION: TAM treatment does not seem to be associated with a higher rate of endometrial cancer in women with breast cancer compared with women treated with AIs or NT.

PURPOSE: To evaluate the incidence and risk factors of neovascular age-related macular degeneration (nAMD) including polypoidal choroidal vasculopathy (PCV) or any type of choroidal neovascularization (CNV) in fellow eyes of unilateral PCV. METHODS: This retrospective study included 48 patients with unilateral PCV. For the initial PCV diagnosis, optical coherence tomography and indocyanine green angiography were performed, and patients with and without neovascularization were compared. RESULTS: Of 48 fellow eyes, 10 (20.8%) had drusen, 9 (18.8%) had retinal pigment epitheliopathy, 9 (18.8%) had irregular retinal pigment epithelium (RPE) elevation, 13 (27.1%) had choroidal vascular dilation, 12 (25%) had choroidal vascular hyperpermeability, and 9 (18.8%) had branching vascular network (BVN) at baseline. The development of nAMD was noted in 8 eyes (17%). The subfoveal choroidal thickness (p = 0.001), irregular RPE elevation (p < 0.001), choroidal vascular dilation (p < 0.001), choroidal vascular hyperpermeability (p < 0.001), and BVN (p < 0.001) in fellow eyes were significantly correlated with development of PCV. After multivariate analysis, BVN (p = 0.045, odds ratio = 24.66) in the fellow eye was the only significant risk factor for the development of nAMD. CONCLUSIONS: PCV or CNV developed in 17% of fellow eyes during the 5 years. Unilateral PCV with contralateral BVN requires careful monitoring for future development of PCV or CNV in fellow eyes.
