Background and objective: Our understanding of homicide-suicide (H-S), a rare yet tragic event, is sparse. While the phenomenon has been studied in the West for many years, only limited literature is available from Asia and none to our knowledge from Pakistan. There is evidence of complexity of the interaction between cultural, societal, and psychological mechanisms underlying this phenomenon; therefore, research findings from the Western countries cannot be directly applied in non-Western societies. Our objective was to study homicide-suicides in Pakistan, describe the characteristics of offenders and victims, determine the types of H-S, and examine possible motives and any events prior to the offense.

Methods: In the absence of any official data on homicide-suicides, we used newspaper surveillance approach of four most widely circulated Pakistani newspapers (one Urdu and three English Daily) for two years (1^st January 2019 to 31^st December 2020). Each case was categorized using the modified Marzuk et al., Tardiff, and Hirsch's classification of homicide-suicides. Descriptive statistics were used to analyze the data that was then compared with published literature.

Results: There were 114 H-S incidents with 198 victims of homicide during the study period, reported in the newspapers. Familial H-S particularly filicide-suicide were predominant, followed by spousal/ consortial H-S. Forty-one (36%) H-S involved multiple victims. The perpetrators across all categories of H-S were predominantly male (67%); the victims were predominantly women and children. Firearms were used in most incidents. The primary motive for the majority of H-S cases was familial, financial, and social stressors.

Conclusions: The study highlights several unique patterns (predominance of familicide, multiple victims including high proportion of children) and a series of vulnerabilities (incidents related mostly to familial/ financial and social stressors) that overlap each other and ultimately lead to this tragic end. There is need to increase our understanding and develop effective evidence-based prevention strategies for H-S in Pakistan. It is also very important to have a national surveillance network and national violent death reporting system in the country for studying H-S cases, and for evaluating the impact of prevention programs.

Objective: To compare the effects of transperitoneal and retroperitoneal approaches for robotic assisted partial nephrectomy (RAPN) in patients with renal cell carcinoma (RCC).

Methods: We conducted a retrospective cohort study on RAPN at Affiliated Hospital of Jiangsu University. Between September 2020 and February 2024, the included patients underwent either transperitoneal approach or retroperitoneal approach. Perioperative status, stress response, quality of life, and incidence of complications were compared between the groups.

Results: A total of 105 patients were included in this analysis, with 54 patients in the Retroperitoneal group, and 51 patients in the Transperitoneal group. The retroperitoneal approach was associated with significantly better perioperative indicators compared to the transperitoneal method (P<0.05). After the surgery, serum levels of interleukin-6 (IL-6), C-reactive protein (CRP), white blood cell count (WBC), and cortisol (Cor) in the Retroperitoneal group were lower than in the Transperitoneal group (P<0.05). The quality-of-life scores of patients in the Retroperitoneal group were higher (P<0.05), but no statistically significant difference in the incidence of complications between the groups (P>0.05).

Conclusions: Compared with the transperitoneal approach, the retroperitoneal method of RAPN is equally safe and is associated with improved perioperative status, lower stress response, and better quality of life for RCC patients.

Objective: To compare the clinical effects of oblique lumbar interbody fusion (OLIF) and lateral lumbar interbody fusion (LLIF) in the treatment of degenerative disc disease of the lumbar spine.

Method: This was a retrospective study. The clinical data of 80 patients with lumbar disc degenerative disease who underwent surgery in Affiliated Hospital of Beihua University from May 2018 to May 2023 were selected. The patients were divided into LLIF group and OLIF group according to surgical methods. Compare the 36-Item Short-Form Health Survey(SF-36), Visual Analog Scale(VAS) scores, Oswesterly Disability Index(ODI), Japanese Orthopedic Association(JOA) scores, Cobb angle, and intervertebral height changes between two groups of patients pre- and posttreatment, and evaluate the differences in clinical efficacy and surgical complications.

Result: Postsurgery, the SF-36 score, VAS score, ODI index, and JOA score of two groups were significantly better than presurgery(p<0.05); After three months of treatment, the improvement in OLIF group was better than LLIF group(p<0.05), while there was no statistically significant difference between the two groups at six months postsurgery(p>0.05). Six months postsurgery, the intervertebral space height and Cobb angle of the two groups were significantly improved compared to presurgery (p<0.05), but there was no significant difference between the groups(p>0.05). There was no difference in clinical efficacy and incidence between the two groups(p>0.05).

Conclusion: LLIF and OLIF may be both safe and effective minimally invasive surgical methods for the treatment of degenerative disc disease of the lumbar spine.

Objective: To compare the pregnancy outcome of the fresh cycle or freeze-thaw cycle embryo transfer of patients treated with a long follicular phase regimen and antagonist regimen, and explore the clinical therapeutic effect of the two regimens.

Methods: This was a retrospective study. The data of a total of 543 patients who underwent in vitro fertilization/intracytoplasmic sperm injection and embryo transfer (IVF/ICSI-ET) or frozen-thawed embryo transfer (FET) in Baoding Maternal and Child Health Care Hospital from January 2020 to December 2022 were retrospectively analyzed in this study and were divided into four group to analyze the basic conditions, medication, laboratory indicators and clinical outcomes after embryo transfer of patients in each group.

Results: The pregnancy rate and implantation rate in Groups A, B and C were higher than those in Group-D, and the differences were statistically significant (p<0.05). The difference in multiple pregnancy rate and abortion rate among groups was not statistically significant (p>0.05). The influencing factors of clinical pregnancy rate were identified by binary Logistic regression analysis. Advanced age was found to be a risk factor for improving the pregnancy rate, while the increase in the number of oocytes retrieved is a protective factor for improving the pregnancy rate. The differences were statistically significant (p<0.05).

Conclusion: The antagonist regimen has a low dosage and short medication time and can achieve a high embryo utilization rate and blastula formation rate, saving time and cost for patients.

Objective: To explore the effect of multimodal analgesia based on the concept of enhanced recovery after surgery (ERAS) in patients undergoing laparoscopic radical gastrectomy (LRG) for gastric cancer (GC).

Methods: Clinical data of 128 patients undergoing LRG for GC, admitted to Sir Run Run Shaw Hospital, Zhejiang University School of Medicine from March 2021 to March 2022, were retrospectively analyzed. Among them, 66 patients received a multimodal analgesic management based on ERAS (ERAS group), and 62 patients were treated with conventional mode of analgesia (control group). Pain levels, rehabilitation status, as well as inflammatory factors and stress response indicators before and after surgery were compared between the two groups.

Results: There was no significant difference in baseline data between the two groups (P>0.05). The postoperative pain and recovery in the ERAS group were better than those in the control group (P<0.05). After the surgery, serum levels of tumor necrosis factor-alpha (TNF-α), Interleukin 6 (IL-6), and C-reactive protein (CRP) in both groups increased compared to before the surgery, but were significantly lower in the ERAS group compared to the control group (P<0.05). After the surgery, serum malondialdehyde (MDA) and xanthine oxidase (XOD) levels in both groups increased, while superoxide dismutase (SOD) levels decreased compared to preoperative levels. The observed postoperative levels of serum MDA and XOD were significantly lower in the ERAS group, while the postoperative SOD levels were higher compared to the control group (P<0.05).

Conclusions: Patients undergoing LRG for GC can benefit from a multimodal pain management plan based on ERAS to reduce postoperative pain, alleviate inflammation, stress responses, and shorten the postoperative recovery process.

Objective: To investigate the correlation between 25-hydroxyvitamin D and H-type hypertension in elderly patients, and to observe the clinical efficacy of vitamin D supplementation in those patients.

Methods: This was a retrospective study. One hundred and twenty elderly hypertensive patients treated at The Affiliated Hospital of Hebei University from June 2022 to June 2023 were randomly divided into Group-A (n=60) with hypertension and elevated homocysteine (Hcy) levels (H-type hypertension), and Group-B(n=60) with hypertension and normal Hcy levels. Blood levels of 25-hydroxyvitamin D and 24 hours ambulatory blood pressure were assessed in both groups of patients upon admission, with the correlation analysis performed simultaneously. The therapeutic effects were compared between the two groups.

Results: Through Pearson correlation analysis, there were negative correlations of serum 25-hydroxyvitamin D levels with 24 hours SSD, 24 hours DSD, dnSBP, and nDBP(all p<0.05). After 12 weeks of treatment, the treatment group had higher 25-hydroxyvitamin D levels and lower 24 hours SBP, 24h DBP, dSBP, dDBP, nSBP, nDBP levels than those of the control group(p<0.05). After treatment, the treatment group had lower blood Hcy, IMT, TC, TG, and LDL-C levels(p<0.05), and higher HDL-C levels(p<0.05) than those of the control group.

Conclusion: Serum 25-hydroxyvitamin D levels in elderly patients with H-type hypertension have negative correlations with 24 hours SSD, 24 hours DSD, dnSBP, and nDBP. Oral vitamin D supplementation for H-type hypertensive patients exhibits significant therapeutic effects, with improvements in 24 hours ambulatory blood pressure monitoring results, blood lipid levels, IMT, and blood Hcy levels after treatment.

Objective: To assess the student's and patients' perspectives about bedside teaching and to identify possible barriers that delay effective bedside teaching.

Methods: This cross-sectional study was conducted at two teaching hospitals in Peshawar with 153 participants through non-probability serial sampling from December 2017 to March 2018. Interview-based validated questionnaires were used and pilot tested as well. Ethical approval was taken with the participant's consent. Data were analyzed using SPSS version 19.0 using descriptive statistics.

Results: Among the total 79 students, all of them completed the questionnaires with a 100% response rate. However, from the 76 patients only 74 responded with a response rate of 97%. The majority of the patients (n=58; 78%) were satisfied with bedside teaching with no problems faced. During the bedside teaching only (n= 13; 18.2%) felt anxious while others, enjoyed (n= 59; 80.5%) with satisfaction and only 13% (n= 10) thought their privacy was breached. The satisfied students with the time spent on bedside teaching were (n= 52; 65.5%) while (n= 30; 38.7%) thought thirty minutes time was not enough. The hurdles faced were lack of practice (37.3%), fear of embarrassment in front of peers (21.3%), and lack of confidence to approach the patient (16%).

Conclusion: The patients showed positive attitude and enjoyed bedside teaching. The students preferred it as a valuable tool for clinical experience. However, time constraints, lack of practice, lack of confidence, confidentiality, and anxiety must be overcome to make bedside teaching a useful method. Effective teaching still requires good teaching methodologies with confidence and competency.

Objective: High levels of glucose during acute pancreatitis (AP) progression influence disease progression by promoting the release of inflammatory cytokines. The aim of this study was to evaluate the effects of both the blood glucose level in patients without diabetes mellitus (DM) and the presence of DM on the severity and course of AP in patients presenting with clinical AP.

Methods: The study included 343 patients who were hospitalized at Van Training and Research Hospital, Turkey and followed up with the diagnosis of AP between 2014 and 2018. The patients were separated into two groups as diabetic and non-diabetic. The relationship between DM and the severity and course of AP was examined in the two groups.

Results: The DM group included 52 (15.1%) patients, and the non- DM group included 291 (84.9%) patients. In the non-DM group, the serum glucose level was <125 mg/dl in 160 (54.9 %) patients, and >125 mg/dl in 131 (45.1 %) patients. In the comparison of AP severity in the diabetic and non-diabetic groups, the rate of severe AP was determined to be significantly higher in the diabetic group according to the Modified Balthazar classification, evaluated from tomographies taken on admission and on the 3rd day (p:0.026, p:0.001, respectively).

Conclusion: Elevated blood glucose is relatively common in patients with AP and has a negative impact on the disease process. A high glucose level can increase the severity of AP and slow healing.

Objective: To explore the choice of embryo transfer schemes for patients with low oocyte retrieval (≤ 3 oocytes).

Methods: A retrospective analysis was conducted on patients with oocyte yields ≤ 3 undergoing in vitro fertilization and embryo transfer (IVF-ET) and frozen embryo transfer (FET) at the Maternity & Child Care Center of Qinhuangdao Reproductive Medicine Department from January 2018 to December 2022. The data included 202 fresh cycles, with 104 cycles in Group-A and 98 cycles in Group-B. Additionally, 87 cycles involved the transfer of frozen embryos from fresh cycles that could not be transplanted for various reasons, with 31 cycles in Group-C and 56 cycles in Group-D. General patient information, embryo transfer details, and clinical pregnancy outcomes in both fresh and frozen cycles were statistically analyzed.

Results: No significant differences were observed between Groups A and C in age, anti-Müllerian hormone (AMH), basal follicle-stimulating hormone (bFSH), body mass index (BMI), duration of infertility, the proportion of patients with diminished ovarian reserve (DOR), oocyte retrieval count, usable embryo count, or the number of transplanted embryos (all p> 0.05). Advanced age was a risk factor for a decreased pregnancy rate, and FET significantly increased the pregnancy rate (p< 0.05, respectively).

Conclusion: For patients under 35 years old with low oocyte retrieval, it is recommended to freeze all embryos when available and then proceed with FET. For patients aged 35 and above, without reducing the pregnancy rate, fresh embryo transfer is recommended to minimize treatment cycle frequency and economic expenses.

Objective: To evaluate the clinical efficacy of comprehensive nursing intervention in pelvic floor and bladder function recovery post-cervical cancer surgery.

Method: This was a retrospective study. A total of 120 patients with cervical cancer undergoing radical surgery at Tangshan People's Hospital from June 2021 to June 2023 were randomly divided into two groups (n=60 cases each group). The control group received routine nursing intervention, while the study group was provided with comprehensive nursing intervention. Comparative analysis was conducted on clinical indicators, postoperative complications, bladder and pelvic floor function recovery, and patient satisfaction before and after intervention in both groups.

Result: In the study group, ambulation time, gastrointestinal function recovery, duration of postoperative drainage tube placement, oral diet resumption time, duration of postoperative vaginal bleeding, and length of hospital stay were significantly shorter than in the control group (all p< 0.05). Bladder function recovery in the study group was superior to that in the control group (p< 0.05). The study group showed lower scores for anorectal disorders, urogenital disorders, and pelvic organ prolapse than the control group (p< 0.05, respectively). Patient satisfaction was 100% in the study group and 85% in the control group, suggesting a statistically significant difference between the two groups (p< 0.05).

Conclusion: Comprehensive nursing intervention deserve to be promoted as it can accelerate postoperative clinical recovery, reduce the incidence of surgical complications, improve pelvic floor and bladder function post-cervical cancer surgery, and enhance patient satisfaction with care.
