Effect of age at first use of oral contraceptives on breast cancer risk: An updated meta-analysis Background: We evaluated the relationship between the age at first use of oral contraceptives (OC) and breast cancer (BC) risk. Methods: We searched PubMed, Embase, and related reviews published through June 28, 2018, and used summary relative risk (RR) and 95% confidence intervals (CIs) to evaluate the cancer risks, and fixed-effects dose–response meta-analysis to assess potential linear and non-linear dose–response relationships. Results: We included 10 studies, with 8585 BC cases among 686,305 participants. The pooled RR for BC was 1.24 (95% CI: 1.10–1.41), with moderate heterogeneities (I2 = 66.5%, P < .001). No significant publication bias was found (P = .584 for Begg test, P = .597 for Egger test). A linear dose–response relationship between the age at first OC use and BC risk was detected (P = .518 for non-linearity). Subgroup analyses were restricted to studies done by BC subtypes, region, sample size, follow-up time and study quality. Inconsistent consequences with no statistical significance were explored when limited to studies from Western countries, study quality <7, sample size <10,000, follow-up time <5 years, and BC subtypes defined by estrogen receptor (ER), progesterone receptor (PR) and human epidermal growth factor receptor-2 (HER-2) expression status in tumor tissue. Sensitivity analyses indicated that our results were stable and reliable after removing each study in turn and omitting studies of adjusted unreported variables. Conclusion: A significant linear relationship between the age at first OC use and BC risk was confirmed. No further consistent differences are noted in multiple aspects of BC subtypes defined by progesterone or ER status.

Individual resection and reconstruction of pelvic tumor with three-dimensional printed customized hemi-pelvic prosthesis: A case report Rationale: Pelvic tumor had great impact on patients’ quality of life. After tumor resection, how to accurately fill bone defect remained challenging for orthopedic surgeons. Due to lack of individual design, high incidence of prosthetic mismatching, and loosening were reported in pelvic reconstruction surgery with conventional modular prostheses. Nowadays, with rapid development of three-dimensional (3D) print technology, pelvic prostheses could be designed according to patients’ own anatomy. The objective of this study was to describe the application of 3D printed customized hemi-pelvic prosthesis for patients with pelvic tumor. Patient concerns: A 62-year-old female had developed severe right joint pain without obvious inducement from 5 months before she sought medical advice. Pain, swelling, and limited range of motion of right joint were founded during physical examination. Diagnosis: The patients were diagnosed as “right acetabulum metastatic carcinoma” Intervention: 3D printed titanium alloy hemi-pelvic prosthesis was designed according the morphology of unaffected side hemi-pelvis and subsequently implanted in surgery to reconstruct the pelvis. 3D printed osteotomy guide and pelvic model were also manufactured and applied to improve accuracy of osteotomy and reduce operation time. X-Ray of pelvis, Harris score, musculoskeletal tumor society score (MSTS) and The MOS item short from health survey (SF-36) were recorded during the period of preoperation, 1, 3, 6, 12 months follow-up after operation. Outcomes: 3D printed hemi-pelvic prosthesis matched precisely with pelvis and implanted successfully. There was no sign of prosthetic loosening within 12 months’ follow-up. No sign of peri-prosthetic infection from laboratory examination. Harris score, MSTS, and SF-36 were gradually increasing during follow-up period. Lessons: Satisfactory effect of pelvic reconstruction could be achieved by 3D printed hemi-pelvic prostheses. It also provided a promising way to the treatment of pelvic tumor in similar cases.

Bereavement practices employed by hospitals and medical practitioners toward attending funeral of patients: A systematic review Objectives: To ascertain bereavement practices offered by hospitals and medical practitioners (MPs), factors that influence the likelihood of MPs’ involvement in funeral attendance, the benefits and barriers to attendance to a patient's funeral as perceived by MPs and the rate of attendance to patients’ funeral by MPs. Design: MEDLINE (Ovid), Embase, PubMed, and Google Scholar were searched with a systematic search structure for randomized controlled trials, comparative observational studies, case series, cross-sectional studies, editorials, and letters. The search was limited to English only. The study was registered with Prospero (Registration Number: CRD42018095368). Results: A total of 381 articles were identified with 46 articles meeting the inclusion criteria. Of the 46, 16 were editorials and 12 were letters. Eighteen were cross-sectional studies conducted in the United States, Canada, Australia, Israel, and Ireland. Year of publication ranged from 1990 to 2017. Of these, 12 were quantitative, 3 were qualitative, and 3 were mixed-method studies. Two of the cross-sectional studies involved family members of deceased patients while others involved MPs. Bereavement practices offered by hospitals included memorial services, letters, and services provided by bereavement coordinators. Bereavement practices employed by MPs included answering or making phone calls, attending family meetings, and sending condolence letters. MPs’ attendance at a patient's funeral was influenced by MPs’ gender, age years of experience the medical specialty. Perceived benefits of MPs’ attendance at a patient's funeral included providing support to the family, extending the professional relationship, illustrating respect to the patient and the family, resolving guilt and personal growth. Barriers to the attendance included a lack of time, blurring of professional boundaries, personal discomfort with death, emotional arousal, and discouragement by colleagues. General practice had an attendance rate of 71%. Attendance rates for palliative care, oncology, and psychiatrists ranged from 63% to 81%, 7.1% to 67%, and 15% to 67%, respectively. Intensivists had an attendance rate of 22%. Conclusion: Several bereavement practices are provided by hospitals and MPs. Funeral attendance is an uncommon bereavement practice. MPs’ attitudes toward attending a patient's funeral are understudied in many specialties. Patient factors that influence MPs’ participation in bereavement practices are poorly understood.

Increased expression of miR-153 predicts poor prognosis for patients with prostate cancer Deregulation of miR-153 has recently been observed in several common human cancer, while miR-153 serves an oncogene or tumor suppressive role in different cancer types. Previously, miR-153 has been identified to be overexpressed in prostate cancer. miR-153 played an important role in promoting proliferation of human prostate cancer cells and presented a novel mechanism of microRNA-mediated direct suppression of phosphatase and tensin homolog (PTEN) expression in prostate cancer cells. Until now, little is known about the clinical significance of miR-153 expression in prostate cancer. The miR-153 expression in 143 pairs of prostate cancer and adjacent non-cancerous prostate tissues was measured by quantitative reverse transcription polymerase chain reaction (qRT-PCR) analysis. Student t test was conducted for intergroup comparison. Pearson correlation test was used for correlation analysis. Survival curves were carried out by the Kaplan–Meier method and evaluated using the log-rank test. Multivariable Cox proportional hazard risk regression model was performed to screen the independent factor affected the prognosis of prostate cancer patients. qRT-PCR analysis showed that the expression of miR-153 was significantly increased in the prostate cancer tissues in comparison with the adjacent noncancerous prostate tissues (P < .001). The high expression of miR-153 in prostate cancer tissues is closely correlated with aggressive clinical pathological parameters such as lymph node metastasis (P = .001); bone metastasis (P < .001); Gleason score (P < .001); and tumor-node-metastasis (TNM) stage (P < .001). Prostate cancer patients with a high expression of miR-153 had an evidently lower 5-year overall survival as compared with those with a low expression of miR-153 (P = .019). Notably, the multivariate Cox regression analysis indicated that miR-153 expression was an independent factor for predicting the 5-year overall survival of prostate cancer patients (hazard ratio [HR] = 2.481, 95% confidence interval [CI]: 1.582–10.727; P = .018). Our study demonstrated that high miR-153 expression was significantly associated with a poor overall survival independently of other factors in prostate cancer. Therefore, miR-153 may be an available biomarker for prostate cancer prognosis.

Clinical outcomes of a modified all-inside arthroscopic repair of anterior talofibular ligament for chronic ankle instability: A preliminary report The present study was conducted to evaluate the clinical outcomes of a modified all-inside arthroscopic repair technique via anterolateral and accessory anterolateral port for anterior talofibular ligament (ATFL) repair. A consecutive series of 32 patients (34 ankles) with chronic ankle instability were included and treated with the modified all-inside arthroscopic repair. The function was assessed using the American Orthopaedic Foot and Ankle Society (AOFAS), visual analog score (VAS) score system, the Sefton grading system, and the anterior drawer test and talar tilt test. A total of 29 cases (30 ankles) were followed up for a mean of 33.7 ± 4.5 (range 30–44) months. Based on the Sefton grading system, 12 patients were regarded as excellent, 13 were good, 2 were fair, and 2 were poor. Twenty-five cases (86.2%) achieved satisfactory functional results. Ankle mobility returned to normal in 93% of patients. The AOFAS scores increased from 55.1 ± 12.3 (range 25–69) preoperatively to 89.7 ± 5.9 (range 74–100) (P < .001) at the last follow-up, while the VAS score decreased significantly (P < .001). There was no wound infection or nerve injury in all cases. In conclusion, based on high satisfaction rate in terms of ankle mobility and low complication rate, the modified all-inside arthroscopic repair of ATFL via anterolateral and accessory anterolateral port appears to be an effective treatment method for chronic ankle instability. Further studies are needed.

Effects of adductor canal block versus femoral nerve block in patients with anterior cruciate ligament reconstruction: A protocol for a systematic review and meta-analysis Objective: It is reported that both adductor canal block (ACB) and femoral nerve block (FNB) are commonly used methods for postoperative analgesia in anterior cruciate ligament (ACL) reconstruction. Currently, no record has compared the efficacy of postoperative pain relief and the influence to quadriceps strength between them. This study aims to provide a protocol to compare the efficacy and safety between ACB and FNB for the postoperative analgesia of ACL reconstruction. Methods: This study will be performed in accordance with the guideline of the Preferred Reporting Items for Systematic Review and Meta-analysis Protocols. Online databases including PubMed, Embase, Web of Science, Cochrane Library, Wanfang database, and the Chinese National Knowledge Infrastructure database will be systematically searched from their inception up May 31, 2019. All randomized controlled trials will be included in present meta-analysis. The quality of enrolled literatures will be evaluated by using the Cochrane Collaboration Risk of bias Tool. Statistical analysis will be calculated by the Review Manager 5.3. Results: This review will investigate the efficacy and safety of ACB compared with FNB in patients undergoing ACL reconstruction. The primary outcomes are visual analog scale, cumulative opioid consumption during 24 hours after surgery, numerical rating scale, and the time to first straight-leg raise. The secondary outcomes include maximal voluntary isometric contraction, stretching torque at 3, 6 months’ follow-up, and adverse effects. Conclusion: Findings of this systematic review and meta-analysis will summarize the current evidence in postoperative analgesia for ACL reconstruction and also provide implications for clinical practice.

Uterine artery ligation before placental delivery during caesarean in patients with placenta previa accreta To investigate the influence of uterine artery ligation before placental delivery during cesarean section on postpartum hemorrhage (PPH) and related complications in patients with placenta previa accreta. A retrospective study was conducted of data from 78 patients with pernicious placenta previa, treated at Fujian Provincial Maternal and Child Health Hospital (Fuzhou, China) between January 2014 and June 2018. Twenty-nine patients underwent uterine arterial ligation before placental delivery (UALBPD), and the other 49 patients in the control group did not undergo peri-paracentesis before the delivery of the placenta. The statistical analysis and data management were performed with SPSS 19.0. The intraoperative and postoperative complications after uterine artery ligation were compared between the 2 groups: in the UALBPD group, no woman (0.0%) underwent a subtotal cesarean hysterectomy, whereas four (8.2%) did so in the control group (P = .24). The mean number of packed red blood cell (RBC) units transfused was 3.7 ± 1.2 in the UALBPD group and 5.7 ± 3.4 units in the control group (P = .0002). The estimated blood loss was 734.2 ± 317.5 mL in the UALBPD group and 1101.6 ± 442.7 mL in the control group (P < .0001). Nine (31.0%) women in the UALBPD group underwent transfusion compared with 38 (77.6%) in the control group (P = .003). The reduction in hemoglobin was 2.63 ± 1.85 g/L in the UALBPD group and 5.41 ± 2.38 g/L in the control group (P < .0001). The reduction in hematocrit was 2.96 ± 4.07 in the UALBPD group and 6.77 ± 8.74 (%) in the control group (P = .009). Bilateral uterine artery ligation before the delivery of the placenta in women with placenta accreta can effectively reduce the amount of intraoperative blood loss, the incidence of PPH, and the risk of complications, such as hysterectomy.

A series of 10 malignant triton tumors in one institution Malignant triton tumor (MTT) is an extraordinarily uncommon and aggressive tumor which have poor prognosis. Malignant peripheral nerve sheath tumors with additional rhabdomyoblasts are found in MTT histologically. The prognosis of patients is poor. The goal of our study is to describe the largest number of cases characteristic and outcome, to our knowledge, such a presentation was not described in the English-language literature until now. From 1999 to 2014, 10 patients (5 women and 5 men) with a malignant triton tumor were treated at our institution. All these cases were followed-up and patient charts were analyzed for outcome. In our study, 3 cases of the Malignant triton tumors originate in the head, 2 cases in the joints, 2 cases in the retroperitoneum, 2 cases in the soft tissues of the thoracic wall, and 1 case in the prostate. Neoplasm associated with pain was the main manifestation. Patients have a poor prognosis. Completely surgical excision of the tumor is the only treatment. Additional radiation or chemotherapy show little effect. Malignant triton tumor is a rare sarcoma. The high probability of developing local recurrence and distant metastases could account for its poor prognosis.

The association between CKD-associated pruritus and quality of life in patients undergoing hemodialysis in Pakistan: A STROBE complaint cross-sectional study Chronic kidney disease (CKD)-associated pruritus is one of the most common symptoms found in patients who undergo dialysis for CKD, leading to a compromised quality of life. This study aimed to investigate the association between CKD-associated pruritus and the quality of life in patients undergoing hemodialysis in Pakistan. A cross-sectional multicenter study was carried out from July 2016 to April 2017 in 2 tertiary care hospitals in Pakistan. Patients aged 18 years and above of both genders, undergoing hemodialysis, understood the Urdu language, and were willing to participate; were included. Of 354 recruited patients with a response rate of 100%, majority (66.1%) of the patients were males. The median (intra-quartile range [IQR]) age of patients was 42.0 [34.0–50.0] years. The prevalence of pruritus was 74%. The median [IQR] score for pruritus was 10.0 (out of possible 25) [8.0–12.0]. Multivariate linear regression revealed a statistically significant association between CKD-associated pruritus with age of patients (β = 0.031; 95% confidence interval [CI] = 0.002–0.061; P = .038), duration of CKD (β = −0.013; 95% CI = −0.023 –−0.003; P = .014) and quality of life (β= −0.949; 95% CI = −1.450; −0.449). The median [IQR] score for health-related quality of life was 52.00 [43.00–58.00]. Prevalence of CKD-associated pruritus was reported to be 74% and it negatively affected the patient's quality of life. Patients with moderate to severe CKD-associated pruritus have poor quality of life. With an increase in intensity of pruritus, the QOL score decreased among the patients undergoing hemodialysis.

Prevention and control strategies for children Kashin–Beck disease in China: A systematic review and meta-analysis Background: To evaluate prevention and control strategies for children with Kashin–Beck disease (KBD) in China through a systematic review and meta-analysis. Methods: We conducted literature searches of articles indexed in Web of Knowledge, PubMed, Springerlink, Elsevier, the Chinese National Knowledge Infrastructure, and Wanfang data until February 2019. Search terms included “Kashin–Beck disease” or “KBD,” and “improvement of water” or “change of grain” or “salt-rich selenium” or “comprehensive measures.” Eligible studies were prospective trials of interventions in endemic area. Data extraction was performed by 2 independent authors using predefined data fields that also included quality evaluation. Results: We screened 1183 potentially relevant articles, and included 22 studies that reported 24 trials, with data from 3700 healthy children and 2961 children KBD. The pooled odds ratios (ORs) and confidence intervals (95% CIs) for primary prevention new incidence in healthy children following interventions to comprehensive measures, change of grain, salt-rich selenium, and improvements of water were 0.15 (0.02, 0.95), 0.15 (0.03, 0.70), 0.19 (0.09, 0.38), and 0.20 (0.09, 0.42), respectively. The OR (95% CI) for clinical improvement in children KBD following interventions to improvement of water, salt-rich selenium, comprehensive measures, and change of grain were 5.03 (3.21, 7.89), 4.39 (3.15, 6.11), 2.98 (1.61, 5.52), and 2.35 (1.59, 3.47), respectively. All interventions showed significant differences and were effective (P < .05). Conclusion: Comprehensive measures and change of grain were the most effective measures in preventing new case, whereas improvement of water and salt-rich selenium resulted in clinical improvements in children KBD.
