Despite publishing and securing research grants being obligatory in research universities, the literature on the factors influencing academic productivity is relatively scarce. Thus, in this study, we aimed to determine the personal and behavioural-related factors that influence the culture of publishing and securing research grants among academicians with lower research-related performance. This cross-sectional study was conducted among 49 academic staff members of Universiti Kebangsaan Malaysia (UKM). A self-administered questionnaire consisting of personal, attitude and behavioural (barriers, perceived stress scale, work extrinsic and intrinsic motivation scale, psychological well-being scale, and basic needs satisfaction scale) questions were distributed during a workshop and online. Simple linear regression (SLR) analyses were performed for each variable, followed by multiple linear regression (MLR) to identify the associated factors of research output. After adjusting for covariates, having a doctoral degree (β=0.396, 95% CI=0.221-2.146, p<0.05) and integrated regulation (β=0.574, 95% CI=0.036-3.612, p<0.05) were found to be associated with research grant acquisition (R2=0.273). Moreover, increasing age (β=0.426, 95% CI=0.088-0.397, p<0.05), living alone (β=0.331, 95% CI=0.944-6.626, p<0.05), having a doctoral degree (β=0.248, 95% CI=0.174-6.747, p<0.05), environmental mastery (β=0.318, 95% CI=0.013-0.347, p<0.05), self-acceptance (β=0.284, 95% CI=0.010-0.242, p<0.05), satisfaction incompetence (β=0.273, 95% CI=0.001-0.200, p<0.05) and relatedness (β=0.280, 95% CI=0.001-0.116, p<0.05) were found to be the factors that influence the publications produced among participants (R2 =0.423). The findings of this study could be used by management to formulate effective strategies to increase the productivity of academics in their research-related performance.

Objective: To retrospectively compare the safety and efficacy of ultrasound-guided radiofrequency ablation (RFA) with parotidectomy for superficial pleomorphic adenoma (PA). Materials and Methods: From March 2022 to October 2023, 88 patients diagnosed with superficial parotid PA underwent either RFA (n = 12; mean age, 47.1 years) or parotidectomy (n = 76; mean age, 47.8 years). Patients in the RFA group were matched to those in the surgery group in a 1:1 ratio using propensity scores based on age, sex, tumor volume, diameter, location, and comorbidities. Ultrasound characteristics, cosmetic scores (0–4), numerical rating scale scores (0–10), and complications were assessed before the procedures and at 1-, 3-, and 6-month follow-ups. Outcomes were compared between baseline and follow-up in the RFA group and between the RFA and surgery groups. Results: In the RFA group, significant reductions in tumor volume were observed between baseline (median, 2.02 cm 3 ) and the 1-month follow-up (median, 1.21 cm 3 ; P = 0.015), between the 1-month and 3-month follow-ups (median, 0.53 cm 3 ; P= 0.002), and between the 3- and 6-month follow-ups (median, 0.23 cm 3 ; P = 0.003). The volume reduction ratios at 1, 3, and 6 months were 39.7%, 79.9%, and 88.0%, respectively. The cosmetic score was significantly lower at 3- and 6-month followup compared to baseline (median 1 and 1 vs. 4, P = 0.04). The numerical rating scale scores did not differ significantly from baseline throughout follow-up. In the propensity score-matched analysis (12 patients per group), RFA was associated with a shorter median procedure time (61.5 vs. 253.3 minutes; P < 0.001), shorter hospital stay (0 vs. 4 days; P < 0.001), and lower cost (1859.9 vs. 3512.4 USD; P < 0.001) than parotidectomy, with no significant difference in overall complication rates (33.3% [4/12] vs. 41.7% [5/12]; P = 1.000). Conclusion RFA may be a safe and effective alternative to surgery for superficial parotid PA, offering a shorter median procedure time, shorter hospital stay, and lower costs.

HDAC7, a member of class IIa HDACs, plays a pivotal regulatory role in tumor, immune, fibrosis, and angiogenesis, rendering it a potential therapeutic target. Nevertheless, due to the high similarity in the enzyme active sites of class IIa HDACs, inhibitors encounter challenges in discerning differences among them. Furthermore, the substitution of key residue in the active pocket of class IIa HDACs renders them pseudo-enzymes, leading to a limited impact of enzymatic inhibitors on their function. In this study, proteolysis targeting chimera (PROTAC) technology was employed to develop HDAC7 drugs. We developed an exceedingly selective HDAC7 PROTAC degrader B14 which showcased superior inhibitory effects on cell proliferation compared to TMP269 in various diffuse large B cell lymphoma (DLBCL) and acute myeloid leukemia (AML) cells. Subsequent investigations unveiled that B14 disrupts BCL6 forming a transcriptional inhibition complex by degrading HDAC7, thereby exerting proliferative inhibition in DLBCL. Our study broadened the understanding of the non-enzymatic functions of HDAC7 and underscored the importance of HDAC7 in the treatment of hematologic malignancies, particularly in DLBCL and AML.

Surgical methods for varicocele remain controversial. This study intends to evaluate the efficacy and safety of different surgical approaches for treating varicocele through a network meta-analysis (NMA). PubMed, Embase, Cochrane, and Web of Science databases were thoroughly searched. In total, 13 randomized controlled trials (RCTs) and 24 cohort studies were included, covering 9 different surgical methods. Pairwise meta-analysis and NMA were performed by means of random-effects models, and interventions were ranked based on the surface under the cumulative ranking curve (SUCRA). According to the SUCRA, microsurgical subinguinal varicocelectomy (MSV; 91.6%), microsurgical retroperitoneal varicocelectomy (MRV; 78.2%), and microsurgical inguinal varicocelectomy (MIV; 76.7%) demonstrated the highest effectiveness in reducing postoperative recurrence rates. In this study, sclerotherapy embolization (SE; 87.2%), MSV (77.9%), and MIV (67.7%) showed the best results in lowering the risk of hydrocele occurrence. MIV (82.9%), MSV (75.9%), and coil embolization (CE; 58.7%) were notably effective in increasing sperm motility. Moreover, CE (76.7%), subinguinal approach varicocelectomy (SV; 69.2%), and SE (55.7%) were the most effective in increasing sperm count. SE (82.5%), transabdominal laparoscopic varicocelectomy (TLV; 76.5%), and MRV (52.7%) were superior in shortening the length of hospital stay. The incidence rates of adverse events for MRV (0), SE (3.3%), and MIV (4.1%) were notably low. Cluster analyses indicated that MSV was the most effective in the treatment of varicocele. Based on the existing evidence, MSV may represent the optimal choice for varicocele surgery. However, selecting clinical surgical strategies requires consideration of various factors, including patient needs, surgeon experience, and the learning curve.

Objective:To explore the clinical effects of various special forms of the descending branch of the lateral circumflex femoral artery (DLCFA) perforator flaps in repairing high-voltage electrical burn wounds on the wrist.Methods:This study was a retrospective observational study. From September 2014 to June 2024, 79 male patients with high-voltage electrical burns on the wrist, aged 20 to 62 years and met the inclusion criteria, were admitted to Beijing Jishuitan Hospital Affiliated to Capital Medical University, with wrist high-voltage electrical burn wound (hereinafter referred to as wrist wound) types being classified as type Ⅱ or type Ⅲ. In the early stage after injury, debridement was performed on the patients' wrists. Based on the wound condition and flap indications, the flow-through, lobed, chimeric, flow-through-lobed, lobed-chimeric, flow-through-chimeric, or flow-through-lobed-chimeric DLCFA perforator flap was employed individually, and the flow-through-chimeric DLCFA perforator flap and tensor fascia lata myocutaneous flap were employed in combination to repair the wounds. The donor site wounds were repaired using direct sutures or skin grafting. The number of various DLCFA perforator flaps resected during surgery and the number of various types of wrist wounds repaired were recorded, as well as the closure status of the donor site wound. The postoperative flap survival, occurrence of vascular crisis, wound or suture site healing, and patency of the reconstructed artery in flow-through flaps were recorded. During follow-up, the appearance of the flap, scar formation, and the presence of thigh muscle herniation were observed.Results:Intraoperatively, 11 flow-through DLCFA perforator flaps were resected to repair 11 type Ⅱ wrist wounds, 13 lobed DLCFA perforator flaps were resected to repair 9 type Ⅱ and 4 type Ⅲ wrist wounds, 16 chimeric DLCFA perforator flaps were resected to repair 16 type Ⅱ wrist wounds, 11 flow-through-lobed DLCFA perforator flaps were resected to repair 5 type Ⅱ and 6 type Ⅲ wrist wounds, 10 lobed-chimeric DLCFA perforator flaps were resected to repair 5 type Ⅱ and 5 type Ⅲ wrist wounds, 6 flow-through-chimeric DLCFA perforator flaps were resected to repair 6 type Ⅱ wrist wounds, 7 flow-through-lobed-chimeric DLCFA perforator flaps were resected to repair 7 type Ⅲ wrist wounds, and 5 flow-through-chimeric DLCFA perforator flaps combined with tensor fascia lata myocutaneous flaps were resected to repair 5 type Ⅲ wrist wounds. Seventy-four patients had their donor site wounds closed by direct suturing, while 5 patients had their donor site wounds closed by skin grafting. Postoperatively, the flaps in 3 patients developed vascular crisis, including 1 case of arterial crisis and 2 cases of venous crises but survived after emergency vascular exploration and other treatments; the remaining flaps survived completely. Postoperatively, 3 patients had seepage beneath their flaps, which were closed after dressing changes; the remaining patients' wounds or suture sites all healed. Anteriography showed that all reconstructed arteries in 35 patients who underwent flow-through flap transplantation were patent postoperatively. During the follow-up period of 3 months to 1 year, 20 patients had bloated flap, while the rest had good flap appearance; linear scars were left in the donor sites that underwent direct wound closure, and the skin-grafted areas of the donor site wounds showed no significant patchy hypertrophic scarring; no thigh muscle herniation occurred.Conclusions:Taking the full advantage of perforator flaps, various special forms of the DLCFA perforator flaps are used to repair the three-dimensionally injury wounds caused by high-voltage electrical burns on the wrist, which not only minimizes the damage to the donor site but also allow the recipient site to be well repaired, showing good appearance in the recent follow-up.
