The treatment of chronic diabetic wounds remains complicated, despite new insight into the cellular and molecular basis of wound healing and cutaneous regeneration. A growing body of clinical trials has shown that platelet release has a notable effectiveness on refractory ulcer healing. However, patients with chronic diabetic ulcers usually have poor general health, and the large-volume blood absence required to produce autologous platelet-rich plasma often causes adverse effects. To overcome the limitation, the homologous platelet gel (PG) from healthy donor was used for the treatment of chronic diabetic lower extremity wound in the study. We show here that homologous derived platelets significantly enhanced EVC304 cell and HaCaT cell proliferation and homologous PG was capable of prompting cell migration. Twenty-one patients with refractory diabetic lower extremity ulcers, who had no response to conventional treatments, were treated in this study. Our data indicated that homologous PG was effective for the enhancement and acceleration of diabetic lower extremity wounds healing. We propose that homologous PG appeared to enhance vascularization and epithelialization, which might induce a quicker healing process and and encourage controlled studies in future.
BACKGROUNDNitrous oxide (N2O) has gained increasing popularity as a recreational drug, causing hallucinations, excitation, and psychological dependence. However, side effects have been reported in recent years. Our case report proposes a correlation among N2O, pulmonary embolism (PE), and deep vein thrombosis (DVT) and emphasizes the role of homocysteine (Hcy) in thrombotic events.CASE SUMMARYA 29-year-old man with long-term N2O abuse sought evaluation after acute chest pain. A diagnostic workup revealed PE, DVT, and hyperhomocysteinemia. The patient was successfully treated with thrombolytic and anticoagulant therapy. Moreover, his Hcy level decreased and returned to normal after Hcy-lowering therapy.CONCLUSIONChronic N2O abuse might increase the risk of PE and DVT, although there have been few studies previously.
Background Antiretroviral therapy (ART) adherence is still suboptimal among some key populations, highlighting the need for innovative tailored strategies. This randomized controlled trial (RCT) aimed to evaluate the effect of a differentiated digital intervention on ART adherence among men who have sex with men (MSM) living with HIV in China. Methods The two-armed parallel RCT was conducted at one HIV clinic in Jinan of China from October 19, 2020, to June 31, 2021. Men were referred by health providers to join the study and then choose one of three digital strategies—text message, only instant message, or instant message plus social media. They were assigned in a 1:1 ratio to the intervention arm or control arm using block randomization, and inside each arm, there were three groups depending on the type of delivering the message. The groups were divided according to participants’ preferred digital strategies. The intervention arm received ART medication messages, medication reminders, peer education, and involved in online discussion. The control arm received messages on health behavior and nutrition. The primary outcome was self-reported optimal ART adherence, defined as not missing any doses and not having any delayed doses within a one-month period. Secondary outcomes included CD4 T cell counts, viral suppression, HIV treatment adherence self-efficacy, and quality of life. Intention-to-treat analysis with generalized linear mixed models was used to evaluate the intervention’s effect. Results A total of 576 participants were enrolled, including 288 participants assigned in the intervention arm and 288 assigned in the control arm. Most were ≤ 40 years old (79.9%) and initiated ART ≤ 3 years (60.4%). After intervention, the proportion of participants achieving optimal ART adherence in the intervention arm was higher than in the control arm (82.9% vs 71.1%). The differentiated digital intervention significantly improved ART adherence (RR = 1.74, 95%CI 1.21–2.50). Subgroup analysis showed one-to-one instant message-based intervention significantly improved ART adherence (RR = 2.40, 95% CI 1.39–4.17). Conclusions The differentiated digital intervention improved ART adherence among MSM living with HIV in China, which could be integrated into people living with HIV (PLWH) management and further promoted in areas where PLWH can access text messaging and instant messaging services.

Aim: Caregivers of patients with rheumatoid arthritis (RA) often experience a sense of burden and depression. This study aimed to determine the degree of burden and depression on caregivers of RA patients and identify characteristics of both patients and caregivers that may contribute to that distress. Methods:A convenience sample of 195 patients with RA and their caregivers completed a demographic questionnaire, Zarit Care Burden Scale, Center Depression Self Rating Scale, Health Assessment Questionnaire Disability Index, and the Short Form Health Survey. Univariate and multivariate regression analysis were used to evaluate contributing factors. Results: Overall, caregivers' feelings of burden and depression were moderate, with 52 (26.7%) feeling depression and 156 (80%) feeling burdened. Caregivers with poorer health (OR = 4.393; 95% CI = 1.155-16.708; P = 0.030) and less education (OR = 6.458; 95% CI = 1.675-24.895; P = 0.007) experienced greater burdens than those with better health and more education. The greatest degree of stress occurred during the first 6 months of providing care and after 5 years of caregiving.Conclusions: Overall occurrence of depression among caregivers is low. Caregivers with poorer health, less education and closer relationship with the patient bear a heavier burden. Healthcare professionals should be aware of these potential problems and provide information and support to ensure the best quality of life for both RA patients and their caregivers.

Based on this meta-analysis, newer P2Y12 inhibitors were significantly more effective than clopidogrel in the events of myocardial infarction and cardiovascular death in patients with ACS, although the incidence of thrombosis in MI-defined bleeding was higher compared with clopidogrel.
Our results indicate that pulmonary or systemic tuberculosis is not a prerequisite for skeletal tuberculosis. Skeletal tuberculosis should be among the differential diagnoses when there is a positive bone scan in patients without a malignancy in an endemic region.
Background Along with the wide spread application and technical development of the flexible and rigid bronchoscopy, the airway foreign body removing method cme to the specific technique for different foreign bodies from the single foreign body forceps. Methods Selected 633 children who were diagnosed as airway foreign bodies by the Department of Respiratory Intervention, Children's Hospital affiliated to Shandong University from January 1st, 2018 to December 31st, 2021, and the airway foreign bodies were diagnosed using bronchoscopy. After comprehensive assessment of the foreign body nature in the airway, the foreign bodies were removed by freezing, laser, electrocoagulation, balloon and other techniques, the success rate of the foreign body removed from the airway was observed, the percentage of the foreign body removed using different techniques, the operation time, and the incidence of post-adverse reactions during operation. Results The success rate using flexible bronchoscope alone to remove foreign bodies in the airway was 99.2%. After flexible bronchoscopy, 19 cases of foreign bodies were removed by vacuum suction alone, 513 cases were removed by foreign body forceps alone, 62 cases were combined with cryotherapy, 2 cases were electrocoagulation, 6 cases were mesh baskets, 3 cases were balloons, 5 cases were laser, and various 18 cases of foreign bodies were invloved by technical combination. 5 cases of flexible bronchoscope combined with rigid bronchoscope combined to remove foreign bodies. The operation time was from 5 min to 1 h, with an average of 20 min. There were 17 cases of hypoxemia (2.7%) during operation, 36 cases (5.7%) of bleeding caused by airway mucosa injury after treatment, and 70 cases (11.2%) of laryngeal edema. The total incidence of adverse reactions was 19.6%, there were no deaths due to foreign bodies and treatment. Conclusions According to different properties of airway foreign bodies, it is safe and effective to select appropriate techniques to remove foreign bodies using the flexible bronchoscope, which can increase the removal rate of airway foreign bodies and reduce the occurrence of serious complications.
Background Consistent and complete adherence is considered an essential requirement for patients on antiretroviral therapy (ART). This study aimed to evaluate the impact of ART duration on ART adherence, identify the trend of complete adherence, and compare the factors associated with ART adherence between short-term and long-term ART group among men who have sex with men (MSM) living with HIV in Jinan of China. Methods MSM living with HIV aged 18 or above and currently on ART were recruited from October to December 2020 using convenience sampling. Univariate and multivariable logistic regressions were used to evaluate the impact of ART duration on adherence and compare factors associated with ART adherence between subgroups. The Mann–Kendall test was used to identify the trend of complete adherence. Results A total of 585 participants were included in analysis, consisting of 352 on short-term ART (ART initiation ≤ 3 years) and 233 on long-term ART (ART initiation > 3 years). Significant difference of complete ART adherence between short-term and long-term ART group was detected (79.8% vs. 69.1%, P = 0.003). Multivariable analysis showed that men with longer ART duration were less likely to report complete ART adherence (AOR = 0.88, 95% CI 0.81–0.95). A descending trend of complete adherence was identified (Z = 1.787, P = 0.037). Alcohol use and lack of medication reminders were barriers to complete adherence for both of the subgroups. Conclusions Sustained efforts to encourage maintaining adherence for a lifetime are necessary, especially for those on long-term ART. Future interventions should be tailored to subgroups with different ART duration and individuals with specific characteristics.
