RESUMEN
BACKGROUND AND OBJECTIVE: COVID-19 led to an unprecedented reliance on virtual modalities to maintain care continuity for patients living with chronic pain. We examined whether there were disparities in virtual specialty pain care for racial-ethnic minority groups during COVID-19. DESIGN AND PARTICIPANTS: This was a retrospective national cohort study with two comparison groups: primary care patients with chronic pain seen immediately prior to COVID-19 (3/1/19-2/29/20) (N = 1,649,053) and a cohort of patients seen in the year prior (3/1/18-2/28-19; n = 1,536,954). MAIN MEASURES: We assessed use of telehealth (telephone or video) specialty pain care, in-person care specialty pain care, and any specialty pain care for both groups at 6 months following cohort inclusion. We used quasi-Poisson regressions to test associations between patient race and ethnicity and receipt of care. KEY RESULTS: Prior to COVID-19, there were Black-White (RR = 0.64, 95% CI [0.62, 0.67]) and Asian-White (RR = 0.63, 95% CI [0.54, 0.75]) disparities in telehealth use, and these lessened during COVID-19 (Black-White: RR = 0.75, 95% CI [0.73, 0.77], Asian-White: RR = 0.81, 95% CI [0.74, 0.89]) but did not disappear. Individuals identifying as American Indian/Alaska Native used telehealth less than White individuals during early COVID-19 (RR = 0.98, 95% CI [0.85, 1.13] to RR = 0.87, 95% CI [0.79, 0.96]). Hispanic/Latinx individuals were less likely than non-Hispanic/Latinx individuals to use telehealth prior to COVID-19 but more likely during early COVID-19 (RR = 0.70, 95% CI [0.66, 0.75] to RR = 1.06, 95% CI [1.02, 1.09]). Disparities in virtual pain care occurred over the backdrop of overall decreased specialty pain care during the early phase of the pandemic (raw decrease of n = 17,481 specialty care encounters overall from pre-COVID to COVID-era), including increased disparities in any VA specialty pain care for Black (RR = 0.81, 95% CI [0.80, 0.83] to RR = 0.79, 95% CI [0.77, 0.80]) and Asian (RR = 0.91, 95% CI [0.86, 0.97] to RR = 0.88, 95% CI [0.82, 0.94]) individuals. CONCLUSIONS: Disparities in virtual specialty pain care were smaller during the early phases of the COVID-19 pandemic than prior to the pandemic but did not disappear entirely, despite the rapid growth in telehealth. Targeted efforts to increase access to specialty pain care need to be concentrated among racial-ethnic minority groups.

Antibody-drug conjugates (ADCs) are drugs that combine monoclonal antibody drugs targeting specific antigens and small molecule cytotoxic drugs through linker molecules. ADCs combine the advantages of high specificity targeting and potent killing effects, achieving precise and efficient targeting of cancer cells. Nowadays, ADCs are one of the hotspots in cancer drug development. Human epidermal growth factor receptor 2 (HER-2) is a known oncogene that can drive the occurrence and development of various types of tumors. HER-2 is also an important tumor target for ADCs approved for solid tumors. Anti-HER-2 ADCs can not only be used to treat HER-2-positive tumors but also effectively target HER-2-low tumors. The emergence of ADCs has broken the traditional classification of HER-2 in tumors, bringing significant treatment breakthroughs for HER-2-low tumors. Anti-HER-2 ADCs are widely used in the treatment of solid tumors and have substantial evidence for HER-2-low tumors. This article presents the progress of various anti-HER-2 ADCs in HER-2-low tumors including breast cancer, gastrointestinal malignancies, urothelial carcinoma, lung cancer. And this article summarizes the current status of preclinical studies, clinical studies, and safety of anti-HER-2 ADCs in order to provide reference for the clinical use of HER-2-low tumors.

Objective: To explore the efficacy and safety of Rivaroxaban in preventing catheter related thrombosis (CRT) in patients with breast cancer who are undergoing central venous catheter chemotherapy, and provide basis for making standardized prevention and treatment strategies. Methods: In this research, a prospective cohort study was adopted, and breast cancer patients who received central venous catheter chemotherapy in Sanhuan Cancer Hospital during September 2020 to March 2022 were selected as a treatment group to take the rivaroxaban anticoagulation therapy with 10 mg.po.qd for one month. The control group got no preventive anticoagulation therapy. Vascular ultrasound examination was taken to confirm the occurrence of CRT, and a chi-square test was done for comparison the disparity between the groups. Logistic regression was applied to analyze the univariate and multivariate factors for the formation of CRT. Results: In the research, a total of 235 patients were selected, and there were a total of 19 035 days of catheterization with 81 days of catheterization on average. While in the control group, the incidence of CRT was 28.0% (33/118), the incidence of CRT in the treatment group was 20.5% (24/117), the difference was no significant (P=0.183). Subgroup analysis results showed that the peripherally inserted central catheter (PICC) was performed in 165 cases with the CRT incidence of 18.2% (30/165) and thrombosis was mostly seen around axillary vein, accounting for 63.3%. Subclavian vein catheterization was performed in 63 cases with the CRT incidence of 39.7% (25/63), and thrombosis was mostly seen around subclavian vein, accounting for 88.0% (22/25). Implantable venous access port was implanted in 7 cases around subclavian vein and internal jugular vein with the CRT incidence of 28.6% (2/7). The patients who developed CRT within 30 days after catheterization accounted for 54.4% (31/57), 22.8% (13/57) in a period during 30 days and 60 days) and 22.8% (13/57) in a period during 60 days and 180 days). The diagnosed CRT patients had been treated with rivaroxaban 15 mg.bid.po for 3 months. During the 3 months, 100.0% of the thrombosis waned, 71.9% (41/57) of the thrombosis waned within 30 days, 19.3% (11/57) in a period during 30 and 60days and 8.8% (5/57) in a period during 60 days and 90 days. Univariate and multivariate analysis indicated that the risk of CRT in subclavian vein catheterization was higher than that in PICC, respectively (OR=2.898, 95% CI:1.386-6.056 P=0.005), and the type of catheterization was an independent factor for the formation of thrombosis. Safety analysis result showed that in the prevention of CRT, rivaroxaban treatment did not induce drug-related bleeding, liver function damage, bone marrow suppression or any other side effects. While CRT diagnosed patients were treated with anticoagulation, they kept the central venous catheter, and the infusion was smooth. These patients all finished the anti-tumor treatment as planned, and no abnormalities like new thrombosis or pulmonary embolism were observed. Conclusions: In the mid-term analysis, the proportion of Rivaroxaban in preventing anticoagulant CRT decreases, but it don't reach statistical significance. The sample size should be further increased for observation. Rivaroxaban is proved effective and very safe in the treatment of CRT, and does not affect the concurrent chemotherapy. Medical personnel should carry out the policy of "early prevention, early detection and early treatment" for CRT so as to improve the patients' quality of life.

Objective: This study collected a real-world data on survival and efficacy of gemcitabine-containing therapy in advanced breast cancer. Aimed to find the main reasons of affecting the duration of gemcitabine-base therapy in advanced breast cancer patients. Methods: Advanced breast cancer patients who received gemcitabine-base therapy from January 2017 to January 2019 were enrolled(10 hospitals). The clinicopathological data, the number of chemotherapy cycles and the reasons for treatment termination were collected and analyzed. To identify the reasons related with continuous treatment for advanced breast cancer and the factors which affect the survival and efficacy. Results: A total of 224 patients with advanced breast cancer were enrolled in this study, with a median age of 52 years (26-77 years), 55.4%(124/224) was postmenopausal. Luminal type were 83 cases, TNBC were 97 cases, and human epidermal growth factor receptor 2 (HER's-2) overexpression were 44. At the analysis, 224 patients who received the gemcitabine-based regimens were evaluated, included 5 complete reponse (CR), 77 partial response (PR), 112 stable disease (SD) and 27 progressive disease (PD). The objective response rate (ORR) was 36.6%(82/224). Seventy patients had serious adverse diseases, including leukopenia (9), neutrophilia (49), thrombocytopenia (15), and elevated transaminase (2). The median follow-up time was 41 months (26~61 months), and the median PFS was 5.6 months. The reasons of termination treatment were listed: disease progression were 90 patients; personal reasons were 51 patients; adverse drug reactions were 18 patients; completed treatment were 65 patients. It was found that progression-free survival (PFS) was significantly longer in patients receiving >6 cycles than that in patients with ≤6 cycles (8.2 months vs 5.4 months, HR=2.474, 95% CI: 1.730-3.538, Pï¼0.001). Conclusions: Gemcitabine-based regimen is generally well tolerated in the Chinese population and has relatively ideal clinical efficacy in the real world. The median PFS is significantly prolonged when the number of treatment cycles are appropriately increased.

Objective: To investigate the clinical characteristics of induced labor in twin pregnancy and the related factors of induced labor failure. Methods: The clinical data of twin pregnant women who underwent induced labor in Peking University Third Hospital from January 2016 to December 2022 were retrospectively analyzed. According to whether they had labor or not after induction, pregnant women were divided into the success group (pregnant women who had labor after induction, 72 cases) and the failure group (pregnant women who did not have labor after induction, 30 cases). Logistic regression was used to analyze the related factors of induction failure in twin pregnant women. Results: The parity and cervical Bishop score in the failure group were significantly lower than those in the success group, while the proportion of dichorionic diamniotic twins, assisted reproductive technology pregnancy and cervical Bishop score <6, postpartum hospital stay and total hospital stay in the failure group were significantly higher than those in the success group (all P<0.05). The proportion of induced labor by artificial rupture of membranes ± oxytocin intravenous infusion in the success group was 72.2% (52/72), which was significantly higher than that in the failure group (46.7%, 14/30; P=0.030). There were no significant differences between the two groups in the gestational age at delivery, the incidence of severe postpartum hemorrhage and blood transfusion, the amount of postpartum hemorrhage, the neonatal weight of two fetuses, the incidence of neonatal asphyxia, and the proportion of neonates admitted to the neonatal intensive care unit (all P>0.05). There were no severe perineal laceration and hysterectomy in all pregnant women. Multivariate logistic regression analysis showed that primipara (OR=3.064, 95%CI: 1.112-8.443; P=0.030) and cervical Bishop score <6 (OR=5.208, 95%CI: 2.008-13.508; P=0.001) were the independent risk factors for induction failure in twin pregnancy. Conclusions: Elective induction of labor in twin pregnancy is safe and feasible. It is helpful to improve the success rate of induction of labor by strictly grasping the timing and indications of termination of pregnancy, choosing the appropriate method of induction according to the condition of the cervix, and actively promoting cervical ripening.

OBJECTIVE: To evaluate the impact of poor sleep quality on occurrence of post-traumatic stress disorder (PTSD) in trauma patients. METHODS: We prospectively recruited 256 trauma patients hospitalized in 4 general hospitals in Zunyi during the period from October, 2021 to November, 2022, and 226 of the participants completed the PTSD survey and assessment. The patients' sleep quality within a month before trauma was estimated using Pittsburgh Sleep Quality Index (PSQI), and their sleep quality within 7 days after admission was monitored by smart bracelet sleep monitoring; the PTSD Checklist-Civilian Version (PCL-C) was used to detect the occurrence of PTSD during the follow-up. RESULTS: The detection rate of PTSD in the patients was 19.47% at 1 month and 17.61% at 3 months after trauma. The patients who developed PTSD had poorer sleep quality before the trauma, as shown by significantly higher PSQI scale scores (P < 0.001), than those without PTSD, and they showed a sleep abnormality rate as high as 72.73% prior to PTSD onset. Within 7 days after admission, the patients developing PTSD had lower sleep quality scores with more frequent night awakenings (P < 0.05). A 1 month and 3 months after trauma, the patients with PTSD had significantly higher PSQI scores than those without PTSD (P < 0.05). CONCLUSION: PTSD is more likely to occur in trauma patients with poor sleep quality before trauma.

Objective: To evaluate the short-term efficacy and safety of a preoperative combination of programmed cell death protein-1 (PD-1) inhibitor with either oxaliplatin + capecitabine (CapeOx) or oxaliplatin + tegafur gimeracil oteracil potassium (SOX) in the treatment of locally advanced immunotherapy-sensitive gastric cancer (LAGC) or adenocarcinoma of the esophagogastric junction (AEG). Methods: The cohort of this retrospective descriptive case series comprised patients with LAGC or AEG whose cancers had been determined to be immunotherapy- sensitive by endoscopic biopsy before treatment in the Gastrointestinal Cancer Center, Unit III, Peking University Cancer Hospital and Institute from 1 August 1 2021 to 31 January 2024. Patients with any one of the following three characteristics were immunotherapy-sensitive: (i) PD-L1 combined positive score (CPS) ≥5; (ii) microsatellite instability-high (MSI-H) / mismatch repair deficiency (dMMR); or (iii) Epstein-Barr virus-encoded RNA (EBER) positivity. All study patients received PD-1 inhibitors combined with CapeOx or SOX as a neoadjuvant or conversion treatment strategy before surgery. Patients with immune system diseases, distant metastases, or human epidermal growth factor receptor 2 positivity were excluded. Factors analyzed included pathological complete response, clinical complete response, major pathological response, R0 resection rate, surgical conversion rate, and safety of the treatment, including immune-related adverse events (irAEs) and surgical complications. Results: The study cohort comprised 39 patients (28 men and 11 women) of median age 62 (range 44-79) years. After the above-described preoperative treatment, radical resection of the 14 tumors that were initially considered unresectable was achieved (surgical conversion rate: 14/14). Twenty-three of the remaining 25 patients underwent radical resection. The last two patients achieved clinical complete responses and opted for a "non-surgical strategy" (watch and wait). Overall, 37 patients (94.9%) underwent radical resection, with an R0 resection rate of 100% (37/37), pathological complete response rate of 48.6% (18/37), and major pathological response rate of 62.2% (23/37). Of the 24 patients with CPS ≥ 5 (non-MSI-H/dMMR and non-EBER positive), 11 achieved pathological complete responses and one with CPS=95 achieved a clinical complete response. Of the eight patients with MSI-H/dMMR, six achieved pathological complete responses and one a clinical complete response. Of the seven patients with EBER positivity, one achieved a pathological complete response. After excluding patients with major pathological complete responses, there was a statistically significant difference in CPS scores between preoperative biopsy specimens and postoperative surgical specimens in 13 patients (7.769±5.570 vs. 15.538±16.870, t=2.287, P=0.041). All patients tolerated preoperative immunotherapy well; nine patients (9/39, 23.1%) had Grade I-II irAEs. There were no Grade III-IV irAEs. The five patients with pyloric obstruction before treatment tolerated normal diets after treatment. The incidence of postoperative complications among all patients who underwent surgery was 18.9% (7/37), including one case of Grade IIIA anastomotic leakage, one of Grade IIIA intestinal obstruction, one of Grade II abdominal hemorrhage, two of Grade II abdominal infection, one of Grade I intestinal obstruction. Additionally, one patient developed COVID-19 postoperatively. All patients recovered with symptomatic treatment. Conclusion: We found that preoperative treatment of patients with LAGC or AEG of one of three types (CPS≥5, dMMR+MSI-H, and EBER positivity) with a PD-1 inhibitor combined with CapeOx or SOX chemotherapy achieved promising effectiveness and safety, with high surgical conversion, R0 resection, and complete response rates.

PURPOSES: This study investigated the feasibility of adalimumab (ADA) dose reduction and withdrawal strategy in children with stable pediatric non-infectious uveitis (PNIU). METHODS: This open-label prospective pilot trial recruited 18 stable PNIU patients (33 eyes) between two and eighteen years old who were treated with standard doses of ADA (20/40 mg every 2 weeks) plus oral methotrexate. The interval of ADA injection was extended to 4 weeks and followed up for 24 weeks. If the uveitis remained stable, ADA was discontinued and followed up for another 24 weeks. ADA was considered successfully stopped if no relapse occurred during this period. The relapse-free survival rate, best corrected visual acuity (BVCA), anterior chamber cell (ACC), vitritis, macular thickness (MT), and serum ADA levels were evaluated. Approval Number: 2021KYPJ201. ClinicalTrials.gov identifier: NCT05155592. RESULTS: The relapse-free survival rate was 22.2% (4/18) at 48 weeks. 33.3% (6/18) of patients relapsed when ADA was given every 4 weeks, while 44.5% of patients (8/18) relapsed after ADA was stopped. The four patients successfully withdrawn from ADA were all diagnosed with BD. No statistically significant differences (p > 0.05) were observed in BCVA and MT between baseline and final follow-up. The proportion of ACC and vitritis exhibited an upward trend (p < 0.05) during follow-up. Serum ADA gradually decreased to zero during follow-up in both non-recurrence and recurrence groups. CONCLUSIONS: In PNIU children who reached remission for 6 months, ADA dose reduction and withdrawal were associated with a high risk of inflammation recurrence. Timely adjustment of ADA to the last effective dosage frequency can regain control of the inflammation. Detection of ADA serum levels in patients with recurrence may help find the appropriate interval of ADA use.
RESUMEN
Objective: Presence of psychotic symptoms seems to be a commonplace in early-onset bipolar disorder (BD). However, few studies have examined their occurrence in adolescent-onset BD. We sought to investigate the frequency of affective and psychotic symptoms observed during the first manic episode in adolescents. Methods: Forty-nine adolescents with bipolar I disorder (DSM-IV criteria) were admitted to a psychiatric hospital during their first acute manic episode. Assessment for current psychiatric diagnosis was performed by direct clinical interview and the DSM-IV version of the Diagnostic Interview for Children and Adolescents (DICA). Results: Teenage inpatients with BD consistently exhibited typical manic features, such as euphoria, grandiosity, and psychomotor agitation. In addition, disorganization and psychotic symptoms were present in 82 and 55% of the total sample, respectively. There was no significant difference in symptoms between early- and late-adolescent subgroups. Remarkably, most patients (76%) reported previous depressive episode(s); of these, 47% had prominent psychotic features in the prior depressive period. Conclusion: These findings suggest that disorganization and psychotic symptoms during the first manic episode are salient features in adolescent-onset BD, and that psychotic depression frequently may precede psychotic mania. Nevertheless, differential diagnosis with schizophrenia should be routinely ruled out in cases of early-onset first psychotic episode.

A vertigem postural fóbica (VPF), o segundo diagnóstico mais freqüente em ambulatório de distúrbios vestibulares, é síndrome somatoforme caracterizada por desequilíbrio subjetivo e ataques breves de vertigem em situações específicas. Em período de 18 meses, a VPF foi observada em 41 pacientes, de 251 atendidos. Vinte e seis apresentavam VPF primária; em 65 por cento havia distúrbios de ansiedade ou depressão, e 15 pacientes tiveram diagnóstico de VPF secundária. O exame neurológico e a avaliação complementar foram normais na maioria dos casos. Observou-se resposta favorável ao tratamento (antidepressivos, benzodiazepínicos, psicoterapia e/ou orientações) em 62 por cento dos pacientes, sem diferença entre os grupos de VPF primária e VPF secundária. Apesar da alta prevalência, a VPF é subdiagnosticada. Entretanto, seu reconhecimento é importante para o tratamento adequado, evitando recorrência e incapacitação.
