Objective To analyze the factors influencing the deterioration of nutritional status after radiotherapy/radiochemotherapy for esophageal cancer,so as to provide reference for nutritional management during antitumor therapy.Methods A total of 106 patients with esophageal cancer who received radiotherapy or radiochemotherapy at Anqing First People's Hospital of Anhui Medical University from Dec.2017 to Dec.2023 were enrolled.Patients'gender,age,surgical history,timing of radiotherapy intervention,synchronous chemoradiotherapy,radiotherapy dose,clinical stage,initial nutritional status,and performance status score were collected.The patient generated subjective global assessment scale(PG-SGA)scores were monitored before and after antitumor treatment.According to the nutritional status at the beginning of enrollment and at the end of radiotherapy,the patients were assigned to deterioration group or non-deterioration(stable or improved)group.The clinical characteristics of the 2 groups were compared.The factors influencing the deterioration of nutritional status were screened by logistic regression analysis.The correlation between nutritional status deterioration and adverse reactions(radiation esophagitis,pulmonary infection,neutropenia,thrombocytopenia,and elevated aminotransferase)was analyzed by Spearman correlation analysis.Results There were no significant differences in gender,radiotherapy dose,initial nutritional status,or performance status score between the 2 groups for the deterioration of nutritional status after radiotherapy(all P＞0.05).The proportions of patients with previous surgical history of esophageal cancer,synchronous chemoradiotherapy,initiation of radiotherapy at less than 90%of target calorie requirement,and clinical stage Ⅳ were significantly higher in the deterioration group than those in the non-deterioration group(all P＜0.05).Logistic regression analysis showed that clinical stage Ⅳ(odds ratio[OR]=4.684,95%confidence interval[CI]1.252-17.519,P=0.022)and previous surgical history of esophageal cancer(OR=7.338,95%CI 1.878-28.666,P=0.004)were the independent adverse risk factors for the deterioration of nutritional status after radiotherapy/radiochemotherapy.The timing of radiotherapy intervention was also an independent risk factor for the deterioration of nutritional status,and taking the tolerance of 70%-90%target energy as the reference level,starting radiotherapy when the tolerance of 90%-100%target energy had the optimal protection of nutritional status(OR=0.166,95%CI 0.050-0.551,P=0.003).Spearman correlation analysis showed that the deterioration of nutritional status was positively correlated with elevated transaminases after radiotherapy(rs=0.283,P=0.003),while it was not correlated with the other adverse reactions(all P＞0.05).Conclusion Under the standard nutritional intervention model,patients with previous surgery and recurrent metastatic esophageal cancer who receive radiotherapy/chemoradiotherapy are still at risk of nutritional status deterioration.Tolerance to 90%-100%target energy requirement may be a more appropriate timing for radiotherapy intervention.When the nutritional status deteriorates during treatment,it is necessary to be alert to the elevated transaminases.

Objective:To explore the influence of social exclusion on the relapse tendency of female drug re-hab patients,and the mediating role of self-esteem and the moderating role of positive psychological capital.Method:A total of 288 female drug rehabilitation patients were selected,and the Social Exclusion Question-naire(SEQ)was used to assess the degree of social exclusion experienced by the patients.The Relapse Tendency Questionnaire(RPQ)was used to evaluate the current tendency of drug relapse.The Rosenberg Self-Esteem Scale(RSES)was used to evaluate the self-esteem level of the patients,and the Positive Psychological Capital Question-naire(PPCQ)was used to evaluate their level of positive psychological capital.Results:The SEQ scores of female drug rehab patients were positively correlated with the RPQ scores(β=0.41,P＜0.001),The RSES scores had a mediating effect between the scores of SEQ and RPQ,with a mediation effect size of 0.09(95％CI:0.04-0.15,accounting for 20.6％of the total effect).The PPCQ scores had a moderating effect between the scores of RSES and RPQ(β=-0.08,P＜0.05)and between the scores of SEQ and RPQ(β=0.10,P＜0.05).Conclusion:So-cial exclusion could not only directly affect but also indirectly affect the relapse tendency through self-esteem of fe-male drug rehab patients.Positive psychological capital could moderate the relationship between social exclusion,self-esteem,and relapse tendency.

Postsurgical hypoparathyroidism is a common cause of hypoparathyroidism, with a variety of clinical manifestations. It is life-threatening in acute and severe cases, and may lead to poor quality of life in chronic patients. It is imperative to consistently enhance the identification and governance of such circumstance. Focusing on the pathophysiological changes, clinical and biochemical features, acute and chronic treatments of postsurgical hypoparathyroidism, a consensus was developed by domestic experts from surgery, endocrinology and nephrology.

Objective: To investigate the epidemiological characteristics of rabies-exposed populations in Anji County, Zhejiang Province from 2017 to 2021, so as to provide insights into rabies control in the county. Methods: All data pertaining to rabies were captured from Monthly Report of Rabies-exposed Populations in Huzhou City and Investigation Form of Multiple Dog Injuries reported by dog injury clinics in Anji County from 2017 to 2021, and the species of animals causing dog injuries, duration, degree and site of exposure, and post-exposure treatment of rabies-exposed populations were descriptively analyzed. Results: Totally 46 186 cases with rabies exposure were reported in dog injury clinics in Anji County from 2017 to 2021, and the rate of exposure appeared a tendency towards a decline year by year (Z=-23.249, P<0.001), with an annual mean exposure rate of 1 739.59/105. The number of cases with exposure to rabies peaked in July and August (10 066 cases, 21.79%). Dogs were predominant animals causing injuries (31 732 cases, 68.70%), and the rate of exposure to dog bites appeared a tendency towards a decline year by year (Z=-35.541, P<0.001). There were 11 350 cases with cat-causing injuries (24.57%), and the rate of exposure to cat bites appeared a tendency towards a rise (Z=14.834, P<0.001). Lower extremity was the main site of exposure (22 364 cases, 48.42%), and the proportions of grade Ⅱ and Ⅲ exposure to rabies were 72.85% and 25.23%, the rates of exposure both appeared a tendency towards a decline (Z=-14.522, P<0.001; Z=-21.820, P<0.001). The proportion of using human rabies immune globulin was 25.72% among populations with grade Ⅲ exposure, which appeared a tendency towards a rise (Z=6.636, P<0.001). Conclusions The rate of exposure to rabies appeared a tendency towards a decline in Anji County from 2017 to 2021. Dogs were predominant animals causing injuries, and the rate of cat bites appeared a tendency towards a rise from 2017 to 2021; however, the proportion of using human rabies immune globulin remains to be improved among populations with grade Ⅲ exposure.

Objective:To systematically evaluate whether the early use of bracing after posterior lumbar fusion has advantages in terms of the improvement of clinical outcomes such as pain, functional disability, fusion rate, and complication rate in patients with lumbar degenerative diseases.Methods:All randomized controlled trials of bracing performed after posterior lumbar fusion in patients with lumbar degenerative diseases were searched in Pubmed, Web of Science, Embase, China national knowledge infrastructure (CNKI) and Wanfang database from January 1990 to May 2022. The data extracted were authors, year of publication, nationality, subject characteristics, sample size, surgical protocol, type and time of bracing, follow-up duration, preoperative and postoperative Oswestry disability index (ODI) and visual analogue scale (VAS), postoperative fusion rate and complication rate. The Cochrane Risk of Bias tool was used to evaluate the risk of bias. The use of fix- or random-effect models was depended on the magnitude of heterogeneity. Data analysis was performed using Stata 17.0 statistical software for meta analysis.Results:A total of five randomized controlled trials were included, all in English, with a total of 362 patients (male 144, female 218). The results of meta-analysis showed that there was no statistically significant difference in the improvement of ODI scores [ MD=1.25, 95% CI(-2.39, 4.88), P=0.501]and VAS scores[ MD=0.21, 95% CI(-0.22, 0.63), P=0.340]between the brace group and the control group after operation. In terms of fusion rate, there was no significant difference between the brace group and the control group[ OR=0.59, 95% CI(0.25, 1.38), P=0.224]. In addition, there was also no significant difference in the incidence of postoperative complications between two groups[ OR=1.12, 95% CI(0.58, 2.15), P=0.735]. Conclusion:The early use of bracing after lumbar fusion has no significant advantages in improving symptoms and functional recovery, fusion rate and surgical complications. The necessity of postoperative bracing after posterior lumbar fusion requires further high-quality research to prove.

Hypercalcemia, a common metabolic complication of malignancies, often referred to as hypercalcemia of malignancy(HCM), is associated with a high incidence and mortality rate. In 2023, the American Society for Bone and Mineral Research and the European Society of Endocrinology released the Treatment of Hypercalcemia of Malignancy in Adults: An Endocrine Society Clinical Practice Guideline. This guideline aimed to address key clinical issues related to adult HCM, refractory and recurrent hypercalcemia, hypercalcemia associated with calcitriol, and hypercalcemia caused by adult parathyroid cancer. This article provides an overview of this guideline and offers some suggestions for managing related conditions in China.

Objective:To evaluate and compare the clinical value of unadjusted fracture risk assessment tool(FRAX) and adjusted FRAX in predicting the risk of hip fracture in patients with type 2 diabetes(T2DM).Methods:In this 10-year retrospective cohort study, 1 730 patients with T2DM were collected from August 2009 to July 2013. The 10-year risk of hip fracture was calculated using the China FRAX model. Hip fracture events during the follow-up period were collected through electronic medical records and telephone interviews. The value of FRAX and adjusted FRAX in predicting the risk of hip fracture in T2DM patients was evaluated from two aspects of discrimination and calibration. Cox regression model was used to investigate the relationship between diabetes related factors and hip fracture.Results:A total of 39 participants(2.3%) experienced hip fracture during a median follow-up of 10 years. The area under the curve of unadjusted FRAX was 0.760, but the calibration ability was poor [calibration χ2: 75.78, P<0.001; calibration ratio(observation/prediction): 3.97(95% CI 2.76~5.17)]. There was no significant improvement in calibration ability of adjusted FRAX. After adjustment for unadjusted or adjusted hip fracture probability calculated by FRAX(FRAX-HF), duration, estimated glomerular filtration rate, insulin use, cerebrovascular diseases, and diabetic peripheral neuropathy were significantly associated with an increased risk of hip fracture( P<0.05). Conclusion:The FRAX tool significantly underestimated the risk of hip fracture in T2DM patients, and there was still significantly underestimation after adjustment due to the failure to eliminate the influence of diabetes-related factors such as disease duration and peripheral neuropathy.

Primary hyperparathyroidism (PHPT) with negative or inconsistent imaging is a significant clinical problem. Surgery is the best chance in curing PHPT. Preoperative imaging is performed for lesion localization to help selecting the proper operative approaches. However,negative or inconsistent imaging could not exclude the diagnosis of PHPT and should not be ruled out the decision of operation. Therefore, for PHPT patients who had indication for surgery but with negative or inconsistent imaging result(s), it is better to transfer the patient to experienced center and surgeons for a proper surgical treatment.

[Summary] Hypercalcemia in pregnancy is a rare condition which brings considerable risks to mother and fetus. The most common cause is primary hyperparathyroidism(PHPT). The untypical symptoms and biochemical tests results add obstacles in the diagnosis of PHPT during pregnancy. The management is difficult, due to restrictions in choices of treatments and lack of clinical guidelines. Severity evaluation which takes consideration of calcium homeostasis during pregnancy is crucial for appropriate management. Parathyroidectomy during the second trimester is recommended for those with high serum calcium levels.

[Summary] A case of primary hyperparathyroidism ( PHPT ) complicated with Graves′disease was reported.The parathyroid lesion( s) could not be identified by repeated MIBI and ultrasonography tests.With the control of hyperthyroidism, medical therapies of hypercalcemia were still not effective, the serum calcium levels continued to be high.Thus, the decision to operate was made.The pathological findings confirmed the diagnosis of parathyroid adenoma.For PHPT patients with clear surgical indications, even though the pre-operative localizing tests are negative, operation is still worth to try.
