RESUMEN
Background: Sexual transmission among men who have sex with men (MSM) has become the major HIV transmission route. However, limited research has been conducted to investigate the association between transactional sex (TS) and HIV incidence in China. Objective: This study aims to investigate HIV incidence and distinguish sociodemographic and sexual behavioral risk factors associated with HIV incidence among MSM who engage in TS (MSM-TS) in China. Methods: We conducted a prospective cohort study using a WeChat-based platform to evaluate HIV incidence among Chinese MSM, including MSM-TS in Ningbo, recruited from July 2019 until June 2022. At each visit, participants completed a questionnaire and scheduled an appointment for HIV counseling and testing on the WeChat-based platform before undergoing offline HIV tests. HIV incidence density was calculated as the number of HIV seroconversions divided by person-years (PYs) of follow-up, and univariate and multivariate Cox proportional hazards regression was conducted to identify factors associated with HIV incidence. Results: A total of 932 participants contributed 630.9 PYs of follow-up, and 25 HIV seroconversions were observed during the study period, resulting in an estimated HIV incidence of 4.0 (95% CI 2.7-5.8) per 100 PYs. The HIV incidence among MSM-TS was 18.4 (95% CI 8.7-34.7) per 100 PYs, which was significantly higher than the incidence of 3.2 (95% CI 2.1-5.0) per 100 PYs among MSM who do not engage in TS. After adjusting for sociodemographic characteristics, factors associated with HIV acquisition were MSM-TS (adjusted hazard ratio [aHR] 3.93, 95% CI 1.29-11.93), having unprotected sex with men (aHR 10.35, 95% CI 2.25-47.69), and having multiple male sex partners (aHR 3.43, 95% CI 1.22-9.64) in the past 6 months. Conclusions: This study found a high incidence of HIV among MSM-TS in Ningbo, China. The risk factors associated with HIV incidence include TS, having unprotected sex with men, and having multiple male sex partners. These findings emphasize the need for developing targeted interventions and providing comprehensive medical care, HIV testing, and preexposure prophylaxis for MSM, particularly those who engage in TS.

OBJECTIVE: To compare clinical effect between open reduction and fixation with cannulated screw and threaded rivet via posteromedial approach versus arthroscopic Endobutton plate fixation in treating posterior cruciate ligament avulsion fractures. METHODS: Clinical data of 38 patients with posterior cruciate ligament avulsion fractures from July 2020 to December 2021 were analyzed retrospectively, and divided into open reduction and internal fixation group (posterior medial approach hollow anchor system fixation) and arthroscopic fixation group (Endobutton with loop plate fixation under arthroscopy). There were 20 patients in open reduction and internal fixation group, including 16 males and 4 females, aged from 26 to 74 years old with an average of (42.9±18.8) years old;13 patients on the left side and 7 patients on the right side;12 patients were classified to typeâ ¡and 8 patiens with type â ¢ according to Meyers-McKeever fractures classification;14 patients were gradeâ ¡and 6 patients were grade â ¢ in back drawer test. There were 18 patients in arthroscopic fixation group, including 11 males and 7 females;aged from 24 to 70 years old with an average of (53.5±13.4) years old;11 patients on the left side and 7 patients on the right side;10 patients were classified to typeâ ¡and 8 patiens with type â ¢ according to Meyers-McKeever fractures classification;11 patients were gradeâ ¡and 7 patients were grade â ¢ in back drawer test. Operation time, blood loss, and quality of immediate reduction were compared between two groups. Knee range of motion, knee back drawer test, and International Knee Documentation Committee(IKDC) grading, KT2000 stability evaluation and Lysholm function score of knee joint were compared at 6 months after operation. RESULTS: All patients were followed up for 8 to 16 months with an average of (12.3±1.9) months. There were no complications such as incision infection, fracture malunion or non-union, and internal fixation loosening occurred. The avulsion fractures of knee joint were reached to imaging healing standard at 6 months after operation. Operation time and blood loss in open reduction and internal fixation group were (56.4±7.1) min and (63.2±10.2) ml, while (89.9±7.4) min and (27.7±8.7) ml in arthroscopic fixation group, respectively, and had significant difference between two groups (P<0.05). There were no differences in immediate reduction quality (χ2=0.257, P=0.612), knee joint range of motion at 6 months after opertaion (t=0.492, P=0.626), knee joint rear drawer test ( χ2=0.320, P=0.572), IKDC classification of knee joint (χ2=0.127, P=0.938), KT2000 stability evaluation (χ2=0.070, P=0.791), and knee Lysholm function score (t=0.092, P=0.282) between two groups. CONCLUSION: Posterior medial approach with hollow anchoring system fixation and arthroscopic Endobutton with loop plate fixation for the treatment of posterior cruciate ligament tibial occlusion avulsion fracture could achieve satisfactory clinical results, and arthroscopic surgery has less bleeding, but also has a longer learning curve and longer operation time than traditional incision surgery. The surgeon needs to make a choice according to clinical situation of patient and their own surgical inclination.

Introduction: In order to enhance the effectiveness of resource allocation, regions must tailor their responses to their specific epidemiological and economic situations. Methods: Utilizing Spectrum software, we projected the cost-effectiveness of 10 chosen HIV interventions in six cities in eastern China from 2019 to 2028. We assessed three scenarios - Base, Achievable, and Idealized - for each city. The analysis included the projected number of HIV infections and deaths averted, as well as the incremental cost-effectiveness ratios for each intervention in the six cities. Results: In Shijiazhuang, Wuxi, Yantai, and Zhenjiang, cities with initially low antiretroviral therapy (ART) coverage, ART showed significant effectiveness, especially for males. Conversely, in Foshan and Ningbo, where ART coverage was notably high, oral pre-exposure prophylaxis (PrEP) for men who have sex with men (MSM) proved effective in the Idealized scenario. MSM outreach, ART for males, and ART for females demonstrated cost-effectiveness across all six cities in both Achievable and Idealized scenarios at the predefined thresholds for each city. Discussion: Maintaining an appropriate coverage rate for outreach to MSM can lead to cost-effectiveness. In cities with low ART coverage, scaling up ART remains a crucial intervention. In regions with high ART coverage, consideration may be given to the utilization of oral PrEP for MSM individuals, requiring budget allocation.
RESUMEN
Heavy metals and per- and polyfluoroalkyl substances (PFASs) have become particularly important when studying the development of depression, a common illness that severely restricts psychosocial functioning and diminishes quality of life. Therefore, the potential joint effects of heavy metal and PFAS exposure on depression, as well as the underlying mechanisms involved, were investigated by using integrated epidemiological and bioinformatic approaches in the present study. A thorough analysis of 7301 samples from the National Health and Nutrition Examination Survey (NHANES) cycles that occurred between 2005 and 2018 was performed. Single-exposure studies have shown that cadmium exposure is positively associated with depression, whereas perfluorooctanesulfonic acid (PFOS) exposure and perfluorodecanoic acid (PFDE) exposure are negatively associated with depression. Furthermore, the Bayesian kernel machine regression (BKMR) and quantile g-computation (QGcomp) models were employed to investigate the collective impact of exposure to mixed metals on depression. Cadmium emerged as the principal contributor to depression. Moreover, the addition of PFAS to the metal mixture had an antagonistic effect on depression, with PFOS having the most prominent influence. Analysis of the effects of co-exposure to cadmium and PFOS confirmed the presence of an antagonistic effect. The inflection points of cadmium and PFOS were determined to be -1.11 and 2.27, respectively. Additionally, exposure to cadmium and PFOS had the opposite effects on two crucial pathways, namely, the rap1 and calcium signaling pathways, which involve core genes related to depression such as ADORA2A, FGF2, and FGFR1. These findings have significant implications for future studies and provide new strategies for exploring the mechanisms underlying co-exposure effects.

BACKGROUND: The association between soy product consumption and cancer risk varies among studies. Therefore, this comprehensive meta-analysis of observational studies examines the association between soy product consumption and total cancer risk. METHODS: This study was conducted following the PRISMA guidelines. Up to October 2023, all eligible published studies were searched through PubMed and Web of Science databases. RESULTS: A total of 52 studies on soy product consumption were included in this meta-analysis (17 cohort studies and 35 case-control studies). High consumption of total soy products (RR: 0.69; 95% CI: 0.60, 0.80), tofu (RR: 0.78; 95% CI: 0.70, 0.86), and soymilk (RR: 0.75; 95% CI: 0.60, 0.93) were associated with reduced total cancer risk. No association was found between high consumption of fermented soy products (RR: 1.18; 95% CI: 0.95, 1.47), non-fermented soy products (RR: 0.95; 95% CI: 0.77, 1.18), soy paste (RR: 1.00; 95% CI: 0.88, 1.14), miso soup (RR: 0.99; 95% CI: 0.87, 1.12), or natto (RR: 0.96; 95% CI: 0.82, 1.11) and cancer risk. A 54 g per day increment of total soy products reduced cancer risk by 11%, a 61 g per day increment of tofu reduced cancer risk by 12%, and a 23 g per day increment of soymilk reduced cancer risk by 28%, while none of the other soy products were associated with cancer risk. CONCLUSION: Our findings suggest that high total soy product consumption, especially soymilk and tofu, is associated with lower cancer risk. More prospective cohort studies are still needed to confirm the causal relationship between soy product consumption and cancer risk.

BACKGROUND: As the HIV epidemic continues to grow, transmitted drug resistance(TDR) and determining relationship of HIV transmission are major barriers to reduce the risk of HIV transmissions.This study aimed to examine the molecular epidemiology and TDR and evaluated the transmission pattern among newly diagnosed people living with HIV/AIDS(PLWHA) in Ningbo city, which could contribute to the development of targeted precision interventions. METHODS: Consecutive cross-sectional surveys were conducted in Ningbo City between January 2018 and December 2021. The HIV-1 pol gene region was amplified and sequenced for drug resistance and genetic transmission network analysis. TDR was determined using the Stanford University HIV Drug Resistance Database. Genetic transmission network was visualized using Cytoscape with the genetic distance threshold of 0.013. RESULTS: A total of 1006 sequences were sequenced successfully, of which 61 (6.1%) showed evidence of TDR. The most common mutations were K103N (2.3%), E138A/G/Q (1.7%) and V179D/E (1.2%). 12 HIV-1 genotypes were identified, with CRF07_BC being the major genotype (43.3%, 332/767), followed by CRF01_AE (33.7%, 339/1006). 444 (44.1%) pol sequences formed 856 links within 120 transmission clusters in the network. An increasing trend in clustering rate between 2018 and 2021(χ2 = 9.546, P = 0.023) was observed. The odds of older age (≥ 60 years:OR = 2.038, 95%CI = 1.072 ~ 3.872, compared to < 25 years), HIV-1 genotypes (CRF07_BC: OR = 2.147, 95%CI = 1.582 ~ 2.914; CRF55_01B:OR = 2.217, 95%CI = 1.201 ~ 4.091, compared to CRF01_AE) were significantly related to clustering. Compared with CRF01_AE, CRF07_BC were prone to form larger clusters. The largest cluster with CRF07_BC was increased from 15 cases in 2018 to 83 cases in 2021. CONCLUSIONS: This study revealed distribution of HIV-1 genotypes, and genetic transmission network were diverse and complex in Ningbo city. The prevalence of TDR was moderate, and NVP and EFV were high-level NNRTI resistance. Individuals aged ≥ 60 years old were more easily detected in the networks and CRF07_BC were prone to form rapid growth and larger clusters. These date suggested that surveillance and comprehensive intervention should be designed for key rapid growth clusters to reduce the potential risk factors of HIV-1 transmission.

BACKGROUND: Men who have sex with men and women (MSMW) are the most important bridge population for HIV transmission. Condom use plays an important role for HIV infection. However the predictors for condom ues with females are not well characterized. METHODS: This was a cross-sectional study. Participants were enrolled by four community-based organizations (CBOs) by offline (bathrooms, bars), and online (gay applications, chat room) from April to December 2019. Electronic questionnare was fulfilled after a face-to-face training led by CBOs. We identified predictors of inconsistent condom use with females by creating a risk score based on regression coefficients. We externally validated this score via an independent cross-sectional survey conducted in Zhejiang Province in 2021. A total of 917, 615 MSMW were included in analysis in 2019 and 2021, seperately. RESULTS: Among 917 MSMW, 73.2% reported heterosexual behavior in the prior 6 months and 38.3% reported inconsistent condom use with females (ICUF) over that time. Compared with heterosexual/unsure MSMW, bisexual MSMW reported more male and female sex partners, higher proportion of inconsistent condom use with males, less commercial sex with males (p < 0.05). Four risky predictors of ICUF were identified: Duration of local residence â¦6 months; more than one male partner in the prior 6 months; inconsistent condom use with males in the prior 6 months; and never heard post-exposure prophylaxis (PEP). The proportions of respondents indicating ICUF in the low- (0), medium- (2-4) and high-risk (6-20) groups (according to our risk scoring system) were 11.7% (14/120), 26.9% (96/357), and 78.1% (125/160), respectively (Ptrend < 0.001). In the validation survey, the respective proportions of those reporting ICUF were 13.4% (15/112), 17.8% (24/185) and 87.3% (96/110) (Ptrend < 0.001). CONCLUSIONS: We developed and validated a predictive risk score for ICUF among MSMW; four factors were identified, of which inconsistent condom use with men was the most important. Risk reduction intervention programs should focus on MSM who report inconsistent condom use with males, never heard PEP, having multiple partners and living in local less than 6 months.

OBJECTIVE: To investigate how the negative regulation of CD44st by miR-138-5p affects the invasive ability of breast cancer cell lines and prognosis in postoperative breast cancer patients. METHODS: RT-PCR, qRT-PCR, and western blot assays were used to detect the expression of CD44s, CD44v6, and CD44st at both mRNA and protein levels. The expression of miR-138-5p in breast cancer cell lines was also evaluated. The binding ability of miR-138-5p to CD44st was determined via a dual-luciferase assay. The CD44 protein expression in breast cancer tissues was detected using immunohistochemistry. A Transwell assay was used to detect the invasive ability of tumor cells. The correlation between CD44st and miR-138-5p mRNA expression in breast cancer tissues was evaluated using qRT-PCR, and the relationship between clinicopathological features was statistically analyzed. RESULTS: CD44s and CD44v6 were highly expressed in MDAMB-231 cell line, while CD44st was highly expressed in MCF-7/Adr and Skbr-3 cells. None of the CD44 isoforms were expressed in MCF-7 cells. The miR-138-5p was highly expressed in MCF-7 cells, but not in MCF-7/Adr, Skbr-3, and MDAMB-231 cells. The dual-luciferase assay suggested that miR-138-5p could bind to wild-type CD44st 3'-UTR, miR-138-5p overexpression significantly inhibited the expression level of CD44 protein in MCF-7/Adr cells, and miR-138-5p + CD44st (3'-UTR)-treated MCF-7/Adr and Skbr-3 cells were significantly less invasive than those in the control group (P < 0.05). RT-PCR results for 80 postoperative breast cancer patients showed that the mRNA expression rate for CD44st was higher in cancer tissues than in paracancerous tissues, and the expression rate of miR-138-5p was higher in paracancerous tissues than in cancerous tissues (P < 0.01). In cancer tissues, CD44st was negatively correlated with miR-138-5p expression, with correlation coefficient r = -0.76 (Pearson's correlation), coefficient of determination R2 = 0.573, F = 106.89, and P < 0.001. The median overall survival value for patients in the low miR-138-5p expression group was 40.39 months [95% confidence interval (CI): 35.59-45.18 months] and 56.30 months (95% CI: 54.38-58.21 months) for patients in the high-expression group, with a log rank (Mantel-Cox) of 13.120, one degree of freedom, and P < 0.001. CONCLUSION: In breast cancer cell lines, miR-138-5p negatively regulated expression of CD44st and affected the invasive ability of tumor cells and patient prognosis after breast cancer surgery.

RESUMEN
@#Pneumonia is a common lower respiratory tract infection, which causes a large disease and economic burden worldwide, and is an important public health problem to be solved urgently. Based on review of publications pertaining to the epidemiology of pneumonia from 2013 to 2023, this article summaries the epidemiological characteristics and main influencing factors of pneumonia. It is found that the epidemiological characteristics of pneumonia vary in different areas; men, the elderly and children are the high-risk groups of pneumonia incidence and mortality; and age, smoking, alcohol consumption, air pollution, comorbidity and vaccination are the main factors affecting the incidence and mortality of pneumonia. Strengthening health education, reducing exposure to risk factors and promoting vaccination are recommended to lower the morbidity and mortality of pneumonia in susceptible populations.
RESUMEN
@#Chronic kidney disease (CKD) is characterized by long course, poor prognosis, multiple complications and high cost of treatment, thus it has become a major public health problem. Based on review of publications pertaining to the epidemiological study of CKD from February 2002 to March 2023, this article summarizes the epidemiological characteristics, risk factors, prevention and control strategies of CKD. It is found that China has the largest number of adult patients with CKD in Asia, and the prevalence of CKD is higher among females and elderly people. The influencing factors for CKD include cardiovascular diseases, diabetes, hypertension and coronavirus disease 2019. Henceforth, it is of vital importance to emphasize three levels of prevention and optimize the CKD management, so as to support for prevention and control of CKD.
RESUMEN
Background: Depressive symptoms were common among HIV/AIDS patients. Previous studies had shown that HIV-infected patients were twice as likely to be diagnosed with depression as the general population. However, only few studies have explored the prevalence and related factors of depressive symptoms among HIV/AIDS in China. Materials and methods: A cross-sectional study was conducted to study the prevalence of depressive symptoms among HIV/AIDS from January to December 2021 through the database of HIV/AIDS antiretroviral therapy and psychological evaluation system in Ningbo, China. The Patient Health Questionnaire-2 (PHQ-2) was used to screen for depressive symptoms (PHQ-2 > 0), the Patient Health Questionnaire-9 (PHQ-9) was used to diagnose depressive symptoms, and multivariate Logistic regression model was carried on to evaluate the related factors. Results: A total of 3,939 HIV/AIDS patients were enrolled, and the age of initiation of antiretroviral therapy was 37.15 (IQR = 28.41-48.73) years. Among them, 3,230 (82.00%) were male, 3,844 (97.59%) were Han nationality, 1,391 (35.49%) were unmarried, 1,665 (42.27%) were homosexual transmission, and 2,194 (55.70%) were HIV-infected patients. There were 265 patients (6.73%) with depressive symptoms, and the proportion of mild, moderate, moderate and severe depressive symptoms was 4.01% (158/3939), 1.65% (65/3939), 0.76% (30/3939), and 0.30% (12/3939), respectively. Multivariate analysis showed that married [odds ratio (OR) = 0.675, 95% CI = 0.501-0.908], divorced or widowed (OR = 0.571, 95% CI = 0.380-0.860), homosexual transmission (OR = 1.793, 95% CI = 1.349-2.396) were associated with depressive symptoms among HIV/AIDS. Conclusion: The prevalence of depressive symptoms among HIV/AIDS patients was 6.73% in Ningbo, China. More attention should be paid to the psychological status of unmarried and homosexual HIV/AIDS patients in Ningbo and timely psychological intervention or treatment should be given to those patients with depressive symptoms.
RESUMEN
Introduction: In order to facilitate human immunodeficiency virus (HIV) treatment and prevention, the resource needs for HIV national strategic planning in developing regions were estimated based on Spectrum, the universal HIV cost-effectiveness analysis software. Methods: Based on the theoretical framework of Spectrum, the study developed a cost measurement tool for HIV, and calculated the cost of HIV prevention and control in 6 sampled cities in China during 2015-2019 using the Spectrum model. Results: From 2015 to 2019, the average annual costs for HIV prevention and control for Shijiazhuang, Yantai, Ningbo, Zhenjiang, Foshan, and Wuxi cities were 46.78, 47.55, 137.49, 24.73, 74.37, and 58.30 million Chinese yuan (CNY), respectively. The per capita costs were 4.37, 6.73, 17.33, 7.77, 17.56, and 8.91 CNY, respectively. In terms of the cost structure, the ratio of preventive intervention funds to therapeutic intervention funds (antiviral treatment) varied in sampled cities. Discussion: Developing comprehensive and systematic HIV fund calculation methods can provide a research basis for rational resource allocation in the field of HIV.
RESUMEN
OBJECTIVE: To discuss the result and long time follow-up of unstable intertrochanteric fracture combined with avascular necrosis of femoral head treated by total hip arthroplasty. METHODS: From March 2008 to October 2014, 23 cases were enrolled and treated by total hip arthroplasty, including 10 males and 13 females, aged 59 to 82 years old with an average of(68.4±10.4) years old. There were 8 cases of type â ¡a fractures, 6 cases of type â ¡b fractures, 9 cases of type â ¢ fractures according to Evans Classification. There were 3 cases of type â ¡a, 3 cases of type â ¡b, 9 cases of type â ¢, 8 cases type â £according to Ficat Classification. The complications were recorded, the joint function was evaluated by Harris score and prosthesis survival rate was analysed. RESULTS: Postoperative complications occurred in 2 cases, one patient had acute periprosthetic infection 3 months after operation, and one patient had hip dislocation 3 months after operation. All 23 patients were followed up for 61 to 110 months with an agerage of (85.1±22.9) months. The Harris score at the final follow-up was 83 to 92 months with an average of(89.8±5.2) months, which was significantly different from that before operation (P<0.05). Imaging showed that all patients had bone healing of intertrochanteric fractures. The 7-year survival rate of prosthesis in 23 patients was 95.7%. CONCLUSION: The symptoms of unstable intertrochanteric fracture combined with avascular necrosis of femoral head could be solved by total hip arthroplasty, and the long time result was satisfied.

OBJECTIVE: To investigate the clinical effect of using lengthened trochanteric osteotomy wire fixation combined with autologous bone graft in patients undergoing revision total hip arthroplasty. METHODS: From December 2010 to December 2018, 18 patients underwent revision of total hip arthroplasty with extended trochanteric osteotomy wire fixation and autogenous bone graft, including 8 males and 10 females with an average age of (78.89±3.32) years old ranging from 68 to 82 years. The time from the initial replacement to the revision was 9 to 22 (16.33±2.93) years. The patients were followed up regularly after operation. The healing time of osteotomy, the time of full weight-bearing activity, Harris score of hip joint and complications were recorded. RESULTS: All 18 patients were followed up for 16 to 38 months with an average of (25.78±6.65) months. The incision length was 16 to 21 cm with an average of (18.89±1.32) cm; the operation time was 105 to 128 min with an average of (115.44±6.59) min, the bleeding volume was 240 to 285 ml with an average of (267.44±13.77) ml. The healing time of osteotomy was 12 to 18 weeks with an average of (15.61±1.75) weeks. Harris score of hip joint was (47.11±5.04) before operation, (76.39±3.85) during full weight-bearing activities, and (82.22±2.76) at the final follow-up(P<0.05). During the follow-up period, there were no complications such as limb shortening, infection, poor incision healing, prosthesis loosening and sinking, and periprosthetic fracture. CONCLUSION: In revision total hip arthroplasty, the use of extended trochanteric osteotomy wire fixation combined with autologous bone graft can achieve satisfactory clinical results, but the surgeon needs to make a systematic plan for the pre-revision, intraoperative and postoperative recovery.

OBJECTIVE: To investigate the value of lumbar quantitative CT (QCT) in vertebroplasty for osteoporotic fracture combined with scoliosis. METHODS: The clinical data of 60 patients with osteoporotic fractures combined with different degrees of scoliosis treated by vertebroplasty from December 2017 to December 2019 were retrospectively analyzed. There were 18 males and 42 females, aged from 65 to 81 (72.63±3.34)years old. All patients were received QCT examination before surgery. According to the QCT value, the patients were divided into osteopenia group(QCT>80 g/L, 10 cases, 12 vertebrae), osteoporosis group(QCT 40-80 g/L, 35 cases, 48 vertebrae) and severe osteoporosis group(QCT<40 g/L, 15 cases, 22 vertebrae). The dispersion and leakage of bone cement in the injured vertebrae of patients with different degrees of QCT value were observed, and the QCT value in the selection of puncture point, correction of Cobb angle and recovery of vertebral height were analyzed in the patients. RESULTS: Among 60 cases of 82 vertebrae, 41 cases of 55 vertebrae were punctured by concave unilateral puncture, according for 67.07%. Among them, there were 2 cases with 2 vertebrae in osteopenia group, 26 cases with 35 vertebrae in osteoporosis group, and 13 cases with 18 vertebrae in severe osteoporosis group. There was significant difference in the number of cases with unilateral or bilateral puncture among the three groups (χ2=13.699, P=0.001); there was no significant difference in the number of cases with bone cement leakage among the three groups (χ2=1.403, P=0.496). The Cobb angle of scoliosis was significantly differentbetween preoperative and postoperative follow-up(P<0.05);the height of injured vertebral body was significantly different between preoperative and postoperative follow-up (P<0.05). CONCLUSION: For patients with osteoporotic fracture combined with scoliosis undergoing vertebroplasty, the severity of osteoporosis should be determined according to lumbar QCT detection, and the concave side of scoliosis should be selected for puncture, which is conducive to improving scoliosis, restoring spinal stability and improving surgical safety.

BACKGROUND: HIV testing and early linkage to care are critical for reducing the risk of HIV transmission. HIV self-testing (HIVST) is a useful tool for increasing HIV testing frequency.This study aimed to investigate HIVST rates among men who have sex with men (MSM), the characteristics of MSM who had HIVST, and factors associated with HIVST uptake among MSM in Ningbo, China. METHODS: A cross-sectional study was conducted from April to October 2019 in Ningbo,China. Participants were aged at least 18 years and having had sexual contact with men in the past year. Proportions were used for categorical variables. Adjusted Odds Ratio (AOR) and 95% Confidence Interval (CI) for characteristics associated with HIVST uptake was processed by multivariable logistic regression models. RESULTS: Among a sample of 699 MSM recruited, 38.2% had reported previous use of an HIV self-test kit. A greater proportion of HIVST users had a higher frequency of HIV testing (≥ 2 times: 70.0% versus 41.2%, p < 0.001) in the past 1 year. The odds of older age (30-39 years: AOR = 0.49, CI 0.32-0.76; more than 40 years: AOR = 0.07, CI 0.04-0.14, compared to 18-29 years), bisexual (AOR = 0.49, CI 0.29-0.84) were lower among HIVST users,and were higher among MSM who were higher education level (high school: AOR = 2.82, CI 1.70-4.69, compared to middle school or less), gay apps use (AOR = 1.86, CI 1.13-3.05), multiple male sex partners (AOR = 1.90, CI 1.29-2.80), frequency of male-male sexual contact ≥ 1 times per week (AOR = 1.86, CI 1.30-2.66), syphilis infection (AOR = 5.48, CI 2.53-11.88). CONCLUSIONS: Further HIVST education should be strengthened for school-aged children and teenagers, and free HIVST kits may be provided to high-risk MSM through gay apps and CBO to achieve the increased HIV testing frequency.

OBJECTIVE: To investigate the clinical effect of double plate combined with iliac bone graft in the treatment of femoral nonunion after intramedullary nailing. METHODS: From December 2008 to December 2017, double plate combined with autogenous iliac bone graft was used to treat femoral nonunion after intramedullary nailing. There were 11 cases, including 10 males and 1 female, aged 35 to 62 years, and the time from fracture to nonunion was 12 to 20 months. According to Judet classification, there were 8 cases of atrophic nonunion and 3 cases of proliferative nonunion. Regular follow-up was conducted after operation to record the fracture healing time, load-bearing activity time and complications, and to observe the repair effect of double plate fixation combined with iliac bone graft on nonunion after femoral shaft fracture operation. RESULTS: All patients were followed up for 12 to 22 months. The operation time was 70 to 130 min and the blood loss was 180 to 350 ml. After operation, 2 cases had knee stiffness, which recovered after passive exercise with CPM machine for 2 weeks;1 case had pain in iliac bone donor area, which was relieved after 3 months. The time of fracture healing was 24 to 40 weeks, and the time of complete weight-bearing activity was 14 to 32 weeks. SF-36 quality of life score at the final follow-up:body pain 70 to 82, activty 70 to 82, social function 72 to 83, the overall health 72 to 82. At the end of the follow-up, there were no complications such as limb shortening, infection, poor wound healing, internal fixation failure (fracture, loosening). CONCLUSION: It is an effective method to treat nonunion of femur after intramedullary nailing by using double plate combined with autogenous iliac bone graft.
