Objective: This study aimed to assess the clinical effect of video-assisted thoracoscopic precise positioning reduction and internal fixation and thoracotomy reduction and internal fixation in the therapy of multiple rib fractures.

Methods: A total of 80 patients with multiple rib fractures in First People's Hospital of Jingzhou from January 2021 to December 2022 were separated into control group (CG, 40 cases) and research group (RG, 40 cases) by random number table method. Patients in the CG received thoracotomy reduction and internal fixation. Patients in the RG received video-assisted thoracoscopic precise positioning reduction and internal fixation. Surgery-related indexes, serum interleukin, visual analogue scale (VAS) was used to evaluate postoperative pain, arterial oxygen saturation (SaO2) and oxygenation index (PaO2/FiO2), and pulmonary function indexes were measured in the two groups.

Results: After surgery, Visual analog scale (VAS) scores at 24 hour after surgery were reduced compared to six hour and 12 hour after surgery (P<0.05). VAS score at 12 hour after surgery was increased relative to 6 h after surgery (P<0.05), and VAS score at six hour, 12 hour as well as 24 hour after surgery in the RG was lessened in comparison with the CG (P<0.05). One day after surgery, SaO₂ and PaO₂/FiO₂ in two groups were elevated compared to before surgery, and those in RG was increased in contrast to the CG (P<0.05). forced expiratory volume (FEV1), forced vital capacity (FVC), peak expiratory flow velocity (PEF) along with FEV1/FVC levels in two groups were increased (P<0.05).

Conclusion: Compared with thoracotomy reduction and internal fixation, video-assisted thoracoscopic accurate positioning and internal fixation in treating patients with multiple rib fractures had a short treatment time, obvious advantages, and strong feasibility.

Background & objective: Hypovitaminosis D has shown to be linked with T2DM development and control in numerous studies. The association of SNPs in genes related to VitD metabolism with T2DM has not been sufficiently studied. Consequently, our aim in the present study was to explore the association between genetic variants in genes connected with VitD, mainly a SNP in GC (rs1155563), a SNP in DHCR7 (rs12785878) and a SNP in CYP2R1 (rs10500804) with glycaemic parameters in females with T2DM in Saudi Arabia.

Methods: The cross-sectional study included 149 females (age 38-52 years) with T2DM from Jeddah, Saudi Arabia (September 2022-March 2023). Blood was extracted from the participants for biochemical tests including measuring VitD [25(OH)D] concentration, parameters of glycaemia (HbA1c, insulin, fasting glucose and insulin sensitivity indices including HOMA2-IR and HOMA2-%β), and for genomic DNA isolation. Sanger DNA sequencing was used to screen for VitD genetic polymorphisms (rs1155563, rs12785878 and rs10500804).

Results: Minor allele frequency for rs1155563C, rs12785878T and rs10500804G was 0.21, 0.23 and 0.37, respectively. Levels of 25(OH)D and glycaemic parameters as well did not show any significant difference between the genotypes of each SNP.

Conclusion: This study showed lack of association of rs1155563 in GC, rs12785878 in DHCR7 and rs10500804 in CYP2R1 with VitD level primarily and with glycaemic parameters secondarily. Additional research is required to explore further other VitD genetic polymorphisms influencing T2DM which might lead consequently to genetically-based personalized management for T2DM.

Objective: To assess the effects of in-bed cycling (IBC) combined with high flow nasal cannula (HFNC) on arterial oxygen and respiratory dynamics in patients with severe respiratory failure (RF).

Methods: We retrospectively collected clinical data of 103 patients with severe RF, admitted to the intensive care unit (ICU) of The Second Affiliated Hospital of Harbin Medical University from March 2021 to March 2023. Among them, 50 patients had HFNC alone (control group), and 53 patients did IBC in addition to HFNC (observation group). We compared arterial oxygen index, lung function, respiratory dynamics, and clinical efficacy between the two groups.

Results: There was no significant difference in the basic data between the two groups (P>0.05). After the treatment, the improvement of the partial pressure of oxygen (PaO₂), PaO₂/fraction of inspired oxygen (FiO₂), arterial oxygen saturation (SaO₂), and oxygen delivery (DO₂) in the observation group was significantly better than that in the control group (P<0.05). After the treatment, the improvement of lung function in the observation group was better than that in the control group (P<0.05). After the treatment, the end expiratory pulmonary pressure (P_tp-ee) and driving pressure (△P_tp) levels in the observation group were significantly higher, and the duration of ICU hospitalization and the incidence of ICU-acquired weakness(ICU-AW) were significantly lower than those in the control group (P<0.05).

Conclusions: IBC combined with HFNC can significantly improve arterial oxygen levels, lung function, and respiratory dynamics in patients with severe RF. IBC in combination with HFNC is associated with shorter stay time in the ICU, reduced of ICU-acquired weakness, and better physical recovery of patients.

Objective: We aimed to evaluate medical school students' knowledge and approaches regarding telehealth.

Method: In this descriptive study, an electronic survey was conducted among students attending the Faculties of Medicine at Health Sciences University. The first part of the Form included questions evaluating individual characteristics and telehealth approaches, and the second part included opinions and suggestions regarding telehealth usage topics.

Results: Of 698 participants, 435 (64.9%) students were in the preclinical period. One hundred nine (15.6%) believed they had sufficient knowledge about telehealth while 399 (57.2%) believed that telehealth should be included in medical education. When asked about their opinions on using telehealth in their professional careers, 298 (42.7%) stated that they considered using them. Those who perceived themselves as having sufficient knowledge about telehealth were more inclined to consider using it more in their professional careers (p=0.000). Participants who believed that healthcare services could be provided through telehealth were more likely to think that disease monitoring would be better, patient follow-up quality would improve, unnecessary hospital admissions would decrease (p<0.05).

Conclusions: The majority of medical faculty students lack sufficient knowledge about telemedicine and believe that education on this topic should be included in the medical curriculum. It is suggested that incorporating pre-clinical courses on telemedicine and providing internship opportunities in practical settings would effectively address this gap.

Background & objective: Acute respiratory failure (ARF) is a life-threatening condition that necessitates intensive care and often results in high morbidity and mortality. Predictive nursing, combined with a risk early warning system, offers a proactive approach to patient care that could potentially improve outcomes in patients with ARF. However, the efficiency of this approach in intensive care settings is still unclear. This study aimed to analyze the effect of predictive nursing based on risk early warning system in patients with acute respiratory failure in intensive care unit (ICU) setting.

Methods: A retrospective cohort study included records of 368 patients admitted to ICU of a tertiary care hospital due to ARF from January 2021 to January 2023. Patients were divided into two groups based on the received care: standard care (control group, n=197) and predictive nursing care based on a risk early warning system (observation group, n=171). Data on demographics, clinical characteristics, complications, Acute Physiology, Age and Chronic Health Evaluation-II (APACHE-II) and Sequential Organ Failure Assessment (SOFA) scores, and duration of hospitalization were collected and analyzed.

Results: The observation group exhibited significantly lower incidence of complications related to ventilator use and shorter durations of mechanical ventilation, ICU stay, and total hospitalization compared to the control group (p<0.001). Furthermore, patients in the observation group had significantly lower APACHE-II and SOFA scores and blood lactate levels at both one week and two weeks post-intervention.

Conclusion: Predictive nursing care based on a risk early warning system significantly improved clinical outcomes and reduced mortality rates in ICU patients with ARF. The results underscore the potential of integrating predictive nursing care into routine practice, thereby transforming the care paradigm for ICU patients with ARF. Future research should explore the applicability of predictive nursing for other clinical conditions and in various healthcare settings.

Objective: To compare voice related quality of life of smoker and non-smoker university teachers.

Method: This Cross-Sectional descriptive study was conducted at Riphah International University over a period of six months January to June, 2022. A sample of N=352 University teachers of both genders, aged 25 to 65 years, who were faculty members and working at least 8 hours per day in teaching positions with at least one-year experience were included in the study. Demographic sheet, Voice Related Quality of Life (VRQOL) and Voice Handicap Index (VHI) were used for data collection and analysis conducted on SPSS Version 21. Mean scores of VRQOL and VHI for smokers and non-smokers were compared using Mann Whitney U Test. & Spearman's correlation was utilized to determine any association between the tool scores. P<0.01 was considered significant.

Results: Results reveal that the mean score of Voice related quality of life scale was significantly (p=0.000) higher in smokers compared to non-smokers indicating worse voice quality in smokers. Similarly, voice handicap index scores were much higher in smokers (p=0.000) indicating more handicap in the smokers.

Conclusion: The study concludes that smoking has a detrimental effect on voice and voice related quality of life of university teachers and voice related quality of life as determined by VRQOL scale is significantly better in non-smokers.

Objective: To determine the effect of Vitamin-D-supplementation on glycemic parameters: glucose levels in blood, insulin, HbA1c, HOMA-IR, and adiponectin in women with gestational diabetes.

Methods: An experimental study was executed at PGMI/LGH of Lahore from June 2020 to June 2021, with 34 Vitamin-D-deficient women who had gestational diabetes (20-26 weeks). All were aged between 21-32 years, randomly and equally divided into controls and cases. Cases received 200,000 IU Vitamin-D-dose. Fasting blood was collected before as well as after treatment from each participant. Spectrophotometry and peroxidase method were used to estimate HbA1c and glucose concentrations respectively. Insulin, adiponectin, and Vitamin-D were assessed by ELISA. To verify data normality, the Shapiro-Wilk test was applied and to prove group comparison Mann-Whitney U, Wilcoxon signed-rank, and Sample-t tests were used via IBM-SPSS version-21.

Results: No difference in blood glucose was found between controls and cases before treatment (p=0.858), while post-treatment, significant reduction found in cases (p=0.019). Before treatment, no difference was noticed in insulin levels of both groups (p=0.44), however, post-treatment, a significant decline was expressed in cases (p=0.001). No difference was found in HOMA-IR between controls and cases before treatment (p=0.14) but post-treatment, significant reduction was observed in cases (p=0.001). Non-significant difference was noted in HbA1c before (p=0.664) and after (p=0.169) treatment in both groups. Non-significant upsurge in adiponectin was observed in cases before (p=0.544) and after (p=0.194) treatment.

Conclusion: Vitamin-D supplementation significantly improves glycemic control in gestational diabetic women, however, its effect on adiponectin was non-significant.

Objective: Retrospective study and analysis of the safety and efficacy of Rh-Rh-endostatinstatin combined with simultaneous radiotherapy in the treatment of cervical cancer.

Methods: A retrospective study was used to enroll cervical cancer patients who received Rh-endostatin combined with simultaneous radiotherapy (observation group) or radiotherapy alone (control group) from January 2019 to December 2022 in the Affiliated Hospital of Hebei University, and RECIST 1.1 criteria were used to evaluate the recent efficacy, and the WHO Adverse Reaction Scale for Anti-cancer Drugs to evaluate the toxic and side effects.

Results: The difference between PR, SD, PD, ORR and DCR of the two groups was not statistically significant(P>0.05), and the CR of the observation group was significantly higher than that of the control group(P<0.05). The proportion of neutropenia, hypertension, arrhythmia, hemoglobin reduction in the observation group was significantly higher than that in the control group, and the proportion of nausea and vomiting was significantly lower than that in the control group(P<0.05), and there was no significant difference in other adverse reactions(P>0.05). After intervention, the CD3+, CD3-CD19+, CD16+CD56+, CEA, CY211 of both groups were significantly lower than before treatment(P<0.05). After treatment, CD3+, CD3-CD19+, CD16+CD56+ were significantly higher in the observation group than in the control group, and WBC and PLT were significantly lower than before treatment(P<0.05). The HPV conversion rate of the observation group was significantly higher than that of the control group(P<0.05).

Conclusions: Our finding revealed that Rh-endostatinstatin combined with simultaneous radiotherapy showed better clinical outcomes and favorable toxic profile than that of radiotherapy alone in the treatment of cervical cancer.

Objective: To examine the potential difference in survival and risk of death between asymptomatic and symptomatic SARS-CoV-2 patients, controlled by age and gender for all the attendance in hospitals of Khyber Pakhtunkhwa (KP), Pakistan.

Methods: In this retrospective study, the medical records of 6273 SARS-CoV-2 patients admitted to almost all hospitals in Khyber Pakhtunkhwa during the first wave of the coronavirus outbreak from March to June 2020 were analysed. The effects of gender, age, and being symptomatic on the survival of SARS-CoV-2 patients were assessed using cure-survival models as opposed to the conventional Cox proportional hazards model.

Results: The prevalence of initially symptomatic patients was 55.8%, and the overall mortality rate was 11.8%. The fitted cure-survival models suggest that age affects the probability of death (incidence) but not the short-term survival time of patients (latency); symptomatic patients have a higher risk of death than their asymptomatic counterparts, but the survival time of symptomatic patients is longer on average; gender has no significant effect on the probability of death and survival time.

Conclusion: The available data and statistical results suggest that asymptomatic and young patients are generally less susceptible to initial infection with SARS-CoV-2 and therefore have a lower risk of death. Our regression models show that uncured asymptomatic patients generally have poorer short-term survival than their uncured symptomatic counterparts. The association between gender and survival outcome was not significant.
