[Review of clinical effects of disk-up sinus reamer(DSR)-based internal sinus floor elevation with implantation in 10 years].

PURPOSE: To analyze the bone remodeling around the implant 10 years after disk-up sinus reamer(DSR)-based internal sinus floor elevation with implantation and to investigate the influence of different factors on implant retention. METHODS: The clinical and imaging data of patients undergoing DSR-based sinus floor elevation with simultaneous implantation were collected from the Department of Dental Implantology, Affiliated Hospital of Qingdao University from January 2008 to December 2011. Panoramic film and CBCT were used to measure the changes of bone mass around implant in different periods. Kaplan-Meier and Log-rank tests were used to analyze the effects of different factors on implant retention with SPSS 26.0 software package. RESULTS: The study included 98 patients with a total of 128 implants. During the follow-up of 0-168 months, 7 implants failed, and the remaining formed good osseointegration and functioned, with a 10-year cumulative retention rate of 94.53%. The height of bone formation was (0.29±0.15) mm at the top and (2.74±0.66) mm in the sinus of 75 implant sites with complete imaging data obtained ten years after surgery. Kaplan-Meier and Log-rank tests showed that 8 factors including initial bone height, elevated bone height, mucosal perforation, implant length, implant torsion, diabetes, smoking and periodontitis had significant effects on implant retention. CONCLUSIONS: The DSR-based internal sinus floor elevation with implantation is a reliable and stable bone augmentation operation for vertical bone defect in maxillary posterior region, with a 10-year cumulative retention rate of no less than 94%. Initial bone height, elevated bone height, mucosal perforation, implant length, implant torsion, diabetes, smoking and periodontitis are the important factors affecting the long-term retention rate of implants.

Medication-based Comorbidity Measures and Prostate Cancer Treatment Selection.

INTRODUCTION: We aimed to assess the association between comorbidities and prostate cancer management. PATIENTS AND METHODS: We studied 12,603 South Australian men diagnosed with prostate cancer between 2003 and 2019. Comorbidity was measured one year prior to prostate cancer diagnosis using a medication-based comorbidity index (Rx-Risk). Binomial logistic regression analyses were used to assess the association between comorbidities and primary treatment selection (active surveillance, radical prostatectomy (RP), external beam radiotherapy (EBRT) with or without androgen deprivation therapy (ADT), brachytherapy, ADT alone, and watchful waiting (WW)). Certain common comorbidities within Rx-Risk (cardiac disorders, diabetes, chronic airway diseases, depression and anxiety, thrombosis, and chronic pain) were also assessed. All models were adjusted for sociodemographic and tumor characteristics. RESULTS: Likelihood of receiving RP was lower among men with Rx-Risk score ≥3 (odds ratio (OR) 0.62, 95%CI:0.56-0.69) and Rx-Risk 2 (OR 0.80, 95%CI:0.70-0.92) compared with no comorbidity (Rx-Risk ≤0). Men with high comorbidity (Rx-Risk ≥3) were more likely to have received ADT alone (OR 1.76, 95%CI:1.40-2.21), EBRT (OR 1.30, 95%CI:1.17-1.45) or WW (OR 1.49, 95%CI:1.19-1.88) compared with Rx-Risk ≤0. Pre-existing cardiac and respiratory disorders, thrombosis, diabetes, depression and anxiety, and chronic pain were associated with lower likelihood of selecting RP and higher likelihood of EBRT (except chronic airway disease) or WW (except diabetes and depression and anxiety). Cardiac disorders and thrombosis were associated with higher likelihood of selecting ADT alone. Furthermore, age had greater effect on treatment choice than the level of comorbidity. CONCLUSION: High comorbidity burden was associated with primary treatment choice, with significantly less RP and more EBRT, WW and ADT alone among men with higher levels of comorbidity. Each of the individual comorbid conditions also influenced treatment selection.

A comparative study between open pre-peritoneal approach versus laparoscopic trans-abdominal pre-peritoneal approach in recurrent inguinal hernia repair: a prospective cohort study.

BACKGROUND: The repair of recurrent inguinal hernias after prosthetic mesh repair is challenging due to the technical complexity and complications associated with it. As well as the increased risk of recurrence due to weakened tissues and distorted anatomy. The Posterior Pre-Peritoneal Approach yields significantly better results than the anterior approach due to its distance from previously scarred tissue. OBJECTIVE: To compare the open pre-peritoneal approach and Laparoscopic trans-abdominal pre-peritoneal approach in the management of recurrent inguinal hernia which was previously managed through an open anterior approach regarding their intra-operative time, the postoperative outcomes in the form of hematoma, wound infection and finally the recurrence within 1-year follow-up. PATIENTS AND METHODS: The current study is a prospective cohort study, a single-center trial conducted from June 2021 to June 2022 in the general surgery department in Ain Shams University Hospitals, which included 74 patients presented with recurrent inguinal hernia who had previous open anterior approach 68(91.8%) males and 6(8.1%) females including a 1-year follow-up postoperative. RESULTS: There were 74 patients in our study with 37 patients in each group. Group (I) underwent an open pre-peritoneal approach and group (II) underwent a Laparoscopic trans-abdominal pre-peritoneal approach. The mean age of the group (I) is 39.51 with a standard deviation of ± 3.49. While in group (II) the mean age is 39.37 with standard deviation ± 3.44 (p = 0.881). From the included 74 patients 67(91.8%) were males and 6(8.1%) were females. As regards the co-morbidities, in group (I) 17(45.9%) patients have no co-morbidities, 11(29.7%) patients have diabetes mellitus, 6(16.2%) patients have hypertension, and 3(8.1%) patients have diabetes and hypertension. Andin group (II) 26(70.3%) patients have no co-morbidities, 6(16.2%) patients have diabetes mellitus, 3(8.1%) patients have hypertension, and 2(5.4%) patients have diabetes and hypertension (p = 0.207). Regarding intra-operative time, the mean time in minutes in the group (I) is 63.33 with a standard deviation of ± 11.95. While in group (II) the mean time in minutes is 81.21 with a standard deviation of ± 18.03 (p = 0.015). The postoperative outcomes were assessed for 1-year follow-up in the form of hematoma, wound infection, and recurrence within 1 year. Regarding the hematoma occurred in 4(10.8%) patients in group (I). While in 2(5.4%) patients in group (II) (p = 0.674). The wound infection was found in 5(13.5%) patients in group(I) and zero patients in group (II) (p = 0.021). Finally, we followed up with the patients for about 1 year to detect the recurrence. Which was found in 3(8.1%) patients in group (I) and 1(2.7%) patient in group (II) (p = 0.615). CONCLUSION: The results of this study demonstrate that both the laparoscopic approach and the open posterior approach are effective for recurrent inguinal hernia following anterior approach mesh hernioplasty, with comparable results. Laparoscopy has been associated with a lower rate of recurrence and overall complications compared to open technique, however, it is difficult to draw definitive conclusions about the preferred option due to its lengthy learning curve and difficulty to perform. Furthermore, the results of this study confirm the previously reported positive results of the posterior pre-peritoneal for recurrent inguinal hernia, particularly when performed by experienced surgeons. Therefore, further prospective randomized population-based trials are necessary to better assess the decision-making for recurrent hernia management and the impact of specialization in abdominal wall surgery in terms of recurrence and complications.

Screening of Associated Factors for Erectile Dysfunction after Radical Prostatectomy and Construction of a Clinical Risk Assessment Model: A Retrospective Study.

OBJECTIVE: In this article, the associated factors for erectile dysfunction (ED) after radical prostatectomy (RP) were explored, and a clinical risk assessment model was constructed. METHODS: A total of 155 patients who underwent RP in People's Hospital of Hunan Province from November 2020, to November 2021, were selected as the study group. In accordance with the results of International Index of Erectile Function (IIEF-5) at 6 months after surgery, 88 patients were included in the ED group (IIEF-5 <22), and 67 patients were included in the non-ED group (IIEF-5 ≥22). Univariate and multivariate logistic regression analyses were conducted to screen the risk factors for ED after RP, and a risk model was constructed on this basis. In addition, 43 patients with ED after RP and 41 patients with non-ED after RP from January 2022, to January 2023, were included in the test group to evaluate the predictive efficacy of the clinical risk assessment model on the basis of the receiver operating characteristic curve. RESULTS: The study group had a lower postoperative IIEF-5 score than before surgery (p < 0.001). The incidence of ED after RP in the study group was 56.77% (88/155). Multivariate analysis showed that advanced age (odds ratio (OR) = 1.155), large prostate volume (OR = 1.077), smoking (OR = 5.676), drinking (OR = 3.495), hypertension (OR = 8.079), diabetes (OR = 6.082), low preoperative serum testosterone (T) level (OR = 0.684) and high preoperative serum endothelin-1 (ET-1) level (OR = 1.192) were risk factors for ED after RP (p < 0.05). A risk model was constructed as follows: Z = 0.144 × (age) + 0.074 × (prostate volume) + 1.736 × (smoking) + 1.251 × (drinking) + 2.089 × (hypertension) + 1.805 × (diabetes) - 0.380 × (preoperative serum T) + 0.175 × (preoperative serum ET-1). The area under curve (AUC), sensitivity, specificity and 95% CI of this model were 0.906, 97.70%, 73.20%, and 0.848-0.964, respectively (p < 0.001). CONCLUSIONS: The clinical risk assessment model constructed on the basis of the above factors provides some references for the scientific prevention and treatment of ED after RP.

Investigation of the reasons for delayed presentation in proliferative diabetic retinopathy patients.

AIM: To investigate reasons for delayed presentation in patients with proliferative diabetic retinopathy (PDR). METHODS: A questionnaire was designed to investigate consecutive PDR patients with delayed presentation who visited our center between January 2021 and December 2021. The questionnaire was divided into four sections: knowledge regarding diabetic retinopathy (DR), attitude toward DR treatment, difficulties adhering to follow-up plans, and medical care. The systemic disease status and severity of DR were recorded. Logistic analysis was undertaken to investigate DR treatment refusal and delay factors. RESULTS: A total of 157 patients were included in this study, with an average age of 50.0 ± 11.6 years. The median glycated hemoglobin level (HbA1c) was 7.8% (IQR 2.5%). Among the 157 eyes, most required vitrectomy intervention (144, 91.7%); 17 developed neovascular glaucoma (NVG), while only 13 required additional photocoagulation. Among the 36 patients with undiagnosed DM, the reason for delayed DR presentation was a lack of awareness of DM status among these patients (36 cases, 100.0%). Most of the patients with a known history of DM exhibited inadequate DR knowledge (29, 24.0%), believed their good visual acuity did not require DR screening (98, 81.0%), and had poorly controlled diabetes (113, 93.3%). Factors related to refusing DR treatment were patients with an inability to receive regular diabetes treatment in internal medicine clinics (OR 6.78, 95% CI 1.73-26.59, p = 0.006), patients who could not tolerate discomfort during ophthalmic examination and treatment (OR 15.15, 95% CI 2.70-83.33, p<0.001), and patients who did not have any retinal abnormalities detected and were not informed about the need for regular screening (OR 2.05, 95% CI 1.36-3.09, p<0.001). CONCLUSIONS: This study investigated the factors contributing to delayed presentation among patients with PDR. Many individuals in the delayed population were found to have undiagnosed DM. Among patients already aware of their DM status, reasons for delay included insufficient knowledge about DR, negative attitudes toward screening and treatment, and difficulties seeking medical care in real-life situations. Furthermore, there needed to be more improvements in the detection, treatment, and follow-up of DR by internal medicine practitioners and ophthalmologists.

Nerve Decompression in the Lower Leg Results in an Improvement in Symptoms in Patients With Both Diabetic and Idiopathic Polyneuropathy.

BACKGROUND: Patients suffering from polyneuropathy often complain of pain, tingling, and numbness sensations, as well as an increased risk of falling with the corresponding subsequent complications. If symptoms persist after conservative treatment options have been exhausted, nerve decompression in the lower extremity, as described by Dellon, can bring about an improvement in symptoms in many patients. Dellon originally reported that this surgery led to very successful outcomes in patients with diabetic polyneuropathy. In this study, we compare our postsurgical results in patients with diabetic versus idiopathic polyneuropathy. METHODS: Thirty-three patients with idiopathic or diabetic polyneuropathy who had undergone Dellon nerve decompression in the lower extremity between 2011 and 2013 were included in the retrospective study. Pain (numeric rating scale [NRS] 0-10; 0, no pain; 10, worst imaginable pain), tingling, numbness, Hoffmann-Tinel sign, and Semes-Weinstein monofilament were assessed in 20 patients with diabetic polyneuropathy and in 13 patients with idiopathic polyneuropathy. RESULTS: Three months after surgery, a significant reduction in pain was evident in patients with diabetic polyneuropathy, from a preoperative level of NRS 4.9 (minimum, 0; maximum, 10) to 2 (minimum, 0; maximum, 8; P = 0.005). Ninety percent of patients complained of tingling ( P = 0.000) before surgery and 18% after surgery, whereas 100% complained of numbness before surgery and 41% ( P = 0.000) after surgery. One hundred percent of patients had no measurable surface sensitivity before surgery (measured with the Semes-Weinstein monofilament), whereas 3 months after surgery, only 24% of patients still had no measurable surface sensitivity ( P = 0.000). A positive Hoffmann-Tinel sign was recorded in 85% of patients before surgery and only in 11% 3 months after surgery ( P = 0.000). In the case of patients with idiopathic polyneuropathy, a reduction in pain was evident 3 months after surgery, from a preoperative level of NRS 3.9 (minimum, 0; maximum, 9) to 2.2 (minimum, 0; maximum, 9; P = 0.058). Seventy-seven percent of patients complained of tingling before surgery and 42% after surgery ( P = 0.111), whereas 92% complained of numbness before surgery and 50% after surgery ( P = 0.030). Seventy-seven percent of patients had no measurable surface sensitivity before surgery (measured with the Semes-Weinstein monofilament), whereas 3 months after surgery, only 33% of patients still had no measurable surface sensitivity ( P = 0.047). A positive Hoffmann-Tinel sign was recorded in 62% of patients before surgery and only in 17% 3 months after surgery ( P = 0.041). CONCLUSIONS: Not only patients with diabetic polyneuropathy but also those with idiopathic polyneuropathy benefit from Dellon nerve decompression surgery in the lower extremities.

Survival of Patients with Chronic Kidney Disease Treated with Radical Cystectomy and Risk Factors of Glomerular Filtration Rate Loss Following Radical Cystectomy: Two Systematic Reviews and Meta-analyses of Interplay Between Radical Cystectomy and Renal Function.

CONTEXT: There is no high-level evidence regarding the risk factors of glomerular filtration rate (GFR) loss following radical cystectomy (RC) and survival outcomes of patients with chronic kidney disease (CKD) undergoing RC. OBJECTIVE: To identify the risk factors of CKD in patients treated with RC for bladder cancer and to assess overall and oncological survival of patients with CKD who underwent RC. EVIDENCE ACQUISITION: According to the Preferred Reporting Items for Systematic Reviews and Meta-analyses statement, two systematic reviews were performed for studies published before September 30, 2022, assessing (1) risk factors of renal function (RF) decline following RC and (2) overall and oncological outcomes of CKD patients treated with RC. EVIDENCE SYNTHESIS: A total of 21 and 17 studies were included for qualitative and quantitative syntheses, respectively. The first meta-analysis of ten studies (15 502 patients) identified these factors to be significantly associated with GFR loss following RC: advanced age, lower baseline RF, higher Charlson Comorbidity Index (CCI), diabetes mellitus, hypertension, postoperative hydronephrosis, ureteroenteric stricture, and locally advanced disease (hazard ratios [HRs] 1.03, 1.22, 1.5, 1.27, 1.24, 1.69, 1.92, and 5.13, respectively), while sex, preoperative hydronephrosis, perioperative chemotherapy, and diversion type were not. The second meta-analysis of seven studies (6900 patients) demonstrated significantly worse metastasis-free, cancer-specific, and overall survival in patients with higher CKD stages than in those with lower stages (HRs 1.54, 2.09, and 1.47, respectively). CONCLUSIONS: Current evidence suggests that older age, lower baseline RF, higher CCI, diabetes mellitus, hypertension, postoperative hydronephrosis, ureteroenteric stricture, and locally advanced disease are associated with long-term GFR loss following RC. In addition, patients with higher stages of CKD have worse long-term overall and oncological outcomes following RC. These data may help in counseling and decision-making regarding therapy and preventive measures. PATIENT SUMMARY: Several factors have been identified that can help identify patients at risk for glomerular filtration rate loss after radical cystectomy (RC). Chronic kidney disease is associated with poor cancer- and non-cancer-specific outcomes following RC.

The Effect of Body Mass Index on Free Flap Breast Reconstruction.

BACKGROUND: Literature addressing the risks associated with increasing body mass index (BMI) for patients undergoing free flap breast reconstruction is limited. Often, an arbitrary BMI cutoff (i.e., BMI of 30 kg/m2) is used to determine candidacy for a free flap without substantial backing evidence. This study utilized a national multi-institutional database to analyze outcomes of free flap breast reconstruction and stratified complications by BMI class. METHODS: Using the 2010 to 2020 National Surgical Quality Improvement Program database, patients who underwent free flap breast reconstruction were identified. Patients were divided into six cohorts based on the World Health Organization BMI classes. Cohorts were compared by basic demographics and complications. A multivariate regression model was created to control for age, diabetes, bilateral reconstruction, American Society of Anesthesiologists class, and operative time. RESULTS: Surgical complications increased with each BMI class, with the highest rates occurring in class I, II, and III obesity, respectively. In a multivariable regression model, the risk for any complication was significant for class II and III obesity (odds ratio [OR]: 1.23, p < 0.004; OR: 1.45, p < 0.001, respectively). Diabetes, bilateral reconstruction, and operative time were independently associated with an increased risk of any complication (OR: 1.44, 1.14, 1.14, respectively, p < 0.001). CONCLUSION: This study suggests that the risks of postoperative complications following free flap breast reconstruction are highest for patients with a BMI greater than or equal to 35 kg/m2, having nearly 1.5 times higher likelihood of postoperative complications. Stratifying these risks by weight class can help guide preoperative counseling with patients and help physicians determine candidacy for free flap breast reconstruction.

Sleeve gastrectomy with one anastomosis bipartition versus one anastomosis gastric bypass: A pilot study.

BACKGROUND: One anastomosis gastric bypass (OAGB) is a new recognized metabolic surgery, but the problem that we cannot screen the excluded stomach is a troubling issue in China. The emergence of sleeve gastrectomy plus one anastomosis bipartition (SG + OAB) makes us see a hope to solve this problem. OBJECTIVES: By comparing the efficacy of the two surgical methods, to evaluate whether SG + OAB surgery can solve the dilemma faced by OAGB that the excluded stomach cannot be screened. METHODS: A retrospective study to compare the patients who underwent OAGB and SG + OAB was conducted. The main outcome measures were (1) operation risk, (2) weight loss, and (3) diabetes remission at 6 months. RESULTS: This study was conducted in the bariatric/metabolic surgical center. From November 2021 to February 2022, a total of 30 patients with obesity who received SG + OAB surgery were recruited. Another matched 60 patients undergoing OAGB were recruited as control group. There was no difference in preoperative age (32.15 ± 9.02 vs. 34.47 ± 7.22; p = .224), female ratio (83% vs. 85%; p = .837), and BMI (36.18 ± 5.30 vs. 34.68 ± 5.58; p = .217) between the two groups. OAGB had a shorter mean operation time (121.67 ± 20.41 vs. 143.50 ± 25.07 min; p < .001) and a lower intraoperative blood loss (21.92 ± 12.35 vs. 32.43 ± 22.01 mL; p = .005), but a longer postoperative flatus passage (2.13 ± 0.43 vs. 1.87 ± 0.43 days; p = .007) compared with the SG + OAB group. Two patients (6.7%) developed major surgical complication in SG + OAB group but no major complication developed in OAGB group. At 6 months after surgery, SG + OAB had a higher %total weight loss than OAGB (31.05 ± 3.12 vs. 28.14 ± 5.43%; p = .015), but diabetes remission rate was similarly high in both groups. CONCLUSIONS: SG + OAB operation had a non-inferior or even better weight loss than OAGB, with a similar glycemic control efficacy. However, the high complication rate of SG + OAB is the major drawback that needs attention.

Association Between the Society for Vascular Surgery (SVS)-WIfI (Wound, Ischemia, Foot Infection) Classification, Wagner-Meggitt Classification, and Amputation Rate in Patients With Diabetic Foot Infection.

Diabetic foot infection (DFI) is a common problem in patients with diabetic foot disease. Amputations and other complications of DFI lead to significant morbidity and mortality. The Society for Vascular Surgery (SVS)-WIfI (wound, ischemia, and foot infection) classification system can evaluate the benefit from revascularization and the risk of amputation in 1 and 3 years. We aimed to evaluate SVS-WIfI and Wagner-Meggitt (WM) prediction of DFI outcome, and to determine factors associated with major amputation and mortality rate. The patients with diabetes who presented between June 2018 and May 2020 with characteristics suggesting a more serious DFI or potential indications for hospitalization were reviewed in this cohort study. Demographic data, clinical characteristics, and type of revascularization were evaluated. One-year and 3-year amputation and mortality rates were the main outcomes. The grading of WM classification and the SVS-WIfI score were compared between amputation and nonamputation groups. Association between mortality and comorbidity were analyzed. One hundred and thirty-one patients admitted with DFI were included in study. And 73.28% had peripheral arterial disease (PAD). The 1-year and 3-year major amputation rates were 16.03% and 26.23%, respectively. Seventy-eight (59.54%) patients required minor amputation to control infection before revascularization. PAD (risk ratio [RR] 1.47: 95% confidence interval [CI] 1.29-1.67, P = .032), benefit from revascularization clinical stage 3 on SVS-WIfI score (RR 4.56: 95%CI 1.21-17.21, P = 0.007), and high WM classification score (RR 9.46: 95% CI 5.65-15.82, P < 0.001) were associated by multivariate analysis with high amputation rates. 1-year & 3-year amputation risk on SVS-WIfI score were not associated with amputation rates in DFI (P = .263 and .496). Only 9 (6.8%) patients were lost to follow up during the 3-year period. WM classification score, SVS-WIfI score on benefit from revascularization, and PAD were strongly associated with major amputation rates in patients with DFI.

Vitreous rebleeding rate after vitrectomy or phacovitrectomy in patients with proliferative diabetic retinopathy: A retrospective study.

BACKGROUND: The most common complication after vitrectomy is the rebleeding in vitreous cavity. It is important to detect the different factors that can increase the vitreous rebleeding rate in these patients. OBJECTIVE: To carry out a retrospective review of the rate of vitreous rebleeding after vitrectomy or phacovitrectomy. METHOD: Retrospective, descriptive and comparative study of patients with a diagnosis of proliferative diabetic retinopathy with phacovitrectomy or vitrectomy procedure. Personal background data, type of surgical intervention and grade of the surgeon who carried out the procedure were obtained. RESULTS: 1227 files of diabetic patients with vitrectomy or phacovitrectomy were reviewed. 65% presented systemic arterial hypertension. The average glomerular filtration rate was 63.50 (±32.36) ml/min/1.73 m2 and glycosylated hemoglobin (HBA1C) of 8% (4.6 to 15%). In the comparison of variables, a significant difference in the rate of vitreous rebleeding was obtained comparing phacovitrectomy with vitrectomy. (p = 0.003), in the relationship between vitrectomy with vitreous rebleeding, an odds ratio of 1.44 was obtained. CONCLUSION: The results obtained show a lower rate of rebleeding in patients undergoing phacovitrectomy in patients with proliferative diabetic retinopathy.

Does diabetes affect outcome or reoperation rate after lumbar decompression or arthrodesis? A matched analysis of the Quality Outcomes Database data set.

OBJECTIVE: Diabetes mellitus (DM) is a known risk factor for postsurgical and systemic complications after lumbar spinal surgery. Smaller studies have also demonstrated diminished improvements in patient-reported outcomes (PROs), with increased reoperation and readmission rates after lumbar surgery in patients with DM. The authors aimed to examine longer-term PROs in patients with DM undergoing lumbar decompression and/or arthrodesis for degenerative pathology. METHODS: The Quality Outcomes Database was queried for patients undergoing elective lumbar decompression and/or arthrodesis for degenerative pathology. Patients were grouped into DM and non-DM groups and optimally matched in a 1:1 ratio on 31 baseline variables, including the number of operated levels. Outcomes of interest were readmissions and reoperations at 30 and 90 days after surgery in addition to improvements in Oswestry Disability Index, back pain, and leg pain scores and quality-adjusted life-years at 90 days after surgery. RESULTS: The matched decompression cohort comprised 7836 patients (3236 [41.3] females) with a mean age of 63.5 ± 12.6 years, and the matched arthrodesis cohort comprised 7336 patients (3907 [53.3%] females) with a mean age of 64.8 ± 10.3 years. In patients undergoing lumbar decompression, no significant differences in nonroutine discharge, length of stay (LOS), readmissions, reoperations, and PROs were observed. In patients undergoing lumbar arthrodesis, nonroutine discharge (15.7% vs 13.4%, p < 0.01), LOS (3.2 ± 2.0 vs 3.0 ± 3.5 days, p < 0.01), 30-day (6.5% vs 4.4%, p < 0.01) and 90-day (9.1% vs 7.0%, p < 0.01) readmission rates, and the 90-day reoperation rate (4.3% vs 3.2%, p = 0.01) were all significantly higher in the DM group. For DM patients undergoing lumbar arthrodesis, subgroup analyses demonstrated a significantly higher risk of poor surgical outcomes with the open approach. CONCLUSIONS: Patients with and without DM undergoing lumbar spinal decompression alone have comparable readmission and reoperation rates, while those undergoing arthrodesis procedures have a higher risk of poor surgical outcomes up to 90 days after surgery. Surgeons should target optimal DM control preoperatively, particularly for patients undergoing elective lumbar arthrodesis.

Glycemic variability and hypoglycemia before and after Roux-en-Y Gastric Bypass and Sleeve Gastrectomy - A cohort study of females without diabetes.

BACKGROUND: Roux-en-Y gastric bypass (RYGB) and sleeve gastrectomy (SG) lead to lower fasting glucose concentrations, but might cause higher glycemic variability (GV) and increased risk of hypoglycemia. However, it has been sparsely studied in patients without preoperative diabetes under normal living conditions. OBJECTIVES: To study 24-hour interstitial glucose (IG) concentrations, GV, the occurrence of hypoglycemia and dietary intake before and after laparoscopic RYGB and SG in females without diabetes. SETTING: Outpatient bariatric units at a community and a university hospital. METHODS: Continuous glucose monitoring and open-ended food recording over 4 days in 4 study periods: at baseline, during the preoperative low-energy diet (LED) regimen, and at 6 and 12 months postoperatively. RESULTS: Of 47 patients included at baseline, 83%, 81%, and 79% completed the remaining 3 study periods. The mean 24-hour IG concentration was similar during the preoperative LED regimen and after surgery and significantly lower compared to baseline in both surgical groups. GV was significantly increased 6 and 12 months after surgery compared to baseline. The self-reported carbohydrate intake was positively associated with GV after surgery. IG concentrations below 3.9 mmol/L were observed in 14/25 (56%) of RYGB- and 9/12 (75%) of SG-treated patients 12 months after surgery. About 70% of patients with low IG concentrations also reported hypoglycemic symptoms. CONCLUSIONS: The lower IG concentration in combination with the higher GV after surgery, might create a lower margin to hypoglycemia. This could help explain the increased occurrence of hypoglycemic episodes after RYGB and SG.

Mapping global new-onset, worsening, and resolution of diabetes following partial pancreatectomy: a systematic review and meta-analysis.

BACKGROUND AND AIMS: Partial pancreatectomy, commonly used for chronic pancreatitis, or pancreatic lesions, has diverse impacts on endocrine and metabolism system. The study aims to determine the global prevalence of new-onset, worsening, and resolution of diabetes following partial pancreatectomy. METHODS: The authors searched PubMed, Embase, Web of Science, and Cochrane Library from inception to October, 2023. DerSimonian-Laird random-effects model with Logit transformation was used. Sensitivity analysis, meta-regression, and subgroup analysis were employed to investigate determinants of the prevalence of new-onset diabetes. RESULTS: A total of 82 studies involving 13 257 patients were included. The overall prevalence of new-onset diabetes after partial pancreatectomy was 17.1%. Univariate meta-regression indicated that study size was the cause of heterogeneity. Multivariable analysis suggested that income of country or area had the highest predictor importance (49.7%). For subgroup analysis, the prevalence of new-onset diabetes varied from 7.6% (France, 95% CI: 4.3-13.0) to 38.0% (UK, 95% CI: 28.2-48.8, P <0.01) across different countries. Patients with surgical indications for chronic pancreatitis exhibited a higher prevalence (30.7%, 95% CI: 21.8-41.3) than those with pancreatic lesions (16.4%, 95% CI: 14.3-18.7, P <0.01). The type of surgical procedure also influenced the prevalence, with distal pancreatectomy having the highest prevalence (23.7%, 95% CI: 22.2-25.3, P <0.01). Moreover, the prevalence of worsening and resolution of preoperative diabetes was 41.1 and 25.8%, respectively. CONCLUSIONS: Postoperative diabetes has a relatively high prevalence in patients undergoing partial pancreatectomy, which calls for attention and dedicated action from primary care physicians, specialists, and health policy makers alike.

ENDOGENOUS FUNGAL ENDOPHTHALMITIS AFTER COVID-19 INFECTION: CASE REPORT AND REVIEW OF LITERATURE.

PURPOSE: The purpose of this study was to describe a case of endogenous endophthalmitis (EE) after severe COVID-19 disease, review patient outcomes with EE after COVID-19 infection, and review evidence regarding risk factors for developing EE. METHODS: This is a review of health records, imaging, intravitreal injection, and pars plana vitrectomy for bilateral fungal EE after severe COVID-19 disease, and is a literature review on outcomes in EE after COVID-19 disease. RESULTS: Sixty-three year-old man with diabetes and hypertension was admitted to hospital for severe COVID-19 disease for 3 months. His stay required intensive care unit admission, intubation, high-dose corticosteroids, tocilizumab, and was complicated by bacteremia, empyema, and fungal esophagitis. He developed floaters and bilateral vision loss (visual acuity 20/40 in the right eye, counting fingers in the left eye) with vitritis 2.5 months into his stay that did not respond to intravitreal voriconazole. Pars plana vitrectomy was performed for both eyes, resulting in visual acuity of 20/40 in the right eye, 20/30 in the left eye. Vitreous cultures were positive for Candida albicans . Endogenous endophthalmitis after COVID-19 disease has been reported in 22 patients to date, and outcomes are poor, with 40%+ of eyes legally blind (20/200 or worse). Although influenced by availability of imaging modalities and degree of training of the evaluating physician, misdiagnosis can affect » of cases, delaying treatment. Age, male sex, and diabetes increase the risk of severe COVID-19, which requires prolonged hospitalization, invasive catheterization, and immunosuppression, which in turn increases the risk of nosocomial infection. CONCLUSION: Low threshold for suspecting EE in patients presenting with floaters and decreased vision after severe COVID-19 disease is necessary to ensure prompt recognition and treatment.

Unique Biology of Pancreatic Ductal Adenocarcinoma Accompanied by Rapidly Impaired Diabetes: A Favorable Long-Term Survival Following Curative Resection.

BACKGROUND: Pancreatic ductal adenocarcinomas (PDACs) are sometimes diagnosed accompanied by rapidly impaired diabetes (PDAC-RID). Although this type of PDAC may have unusual biological features, these features have not been explained. METHODS: Patients with PDAC who underwent upfront pancreatectomy between 2010 and 2018 were retrospectively reviewed. PDAC-RID was defined as a glycated hemoglobin (HbA1c) value of ≥ 8.0% of newly diagnosed diabetes, and acute exacerbation of previously diagnosed diabetes. Other patients were classified as PDAC with stable glycometabolism (PDAC-SG). Clinicopathological factors, long-term survival rates, and recurrence patterns were evaluated. RESULTS: Of the 520 enrolled patients, 104 were classified as PDAC-RID and 416 as PDAC-SG. There was no significant difference regarding TNM staging, resectability, or adjuvant chemotherapy rate between the groups. However, 5-years cancer-specific survival (CSS) was significantly higher in the PDAC-RID group than in the PDAC-SG group (45.3% vs. 31.1%; p = 0.02). This survival difference was highlighted in relatively early-stage PDAC (≤ pT2N1) (CSS: 60.8% vs. 43.6%; p = 0.01), but the difference was not significant for advanced-stage PDAC. A multivariate analysis of early-stage PDAC showed that PDAC-SG was an independent risk factor of shorter CSS (hazard ratio 1.76; p = 0.02). The hematogenous metastatic rate in early-stage PDAC was lower in the PDAC-RID group than in the PDAC-SG group (18.3% vs. 35.8%; p = 0.01). CONCLUSIONS: PDAC-RID showed a favorable long-term survival rate after curative resection with low hematogenous metastases, which may be due to its unique biology.

Improving the outcomes for people with diabetes undergoing surgery: An observational study of the Improving the Peri-operative Pathway of People with Diabetes (IP3D) intervention.

AIMS: We evaluated the effectiveness of an intervention to improve the care of people with diabetes undergoing surgery when implemented across multiple organisations. METHODS: This was an observational study using routinely collected data. Eight hospitals in England implemented the Improving the Peri-operative Pathway of People with Diabetes (IP3D) intervention, with pre-implementation data collected from 1st February to 31st July 2019 and post-implementation data collection within the period 1st February to 31st October 2021. Key elements were the use of a patient empowering peri-operative passport and the employment of a peri-operative diabetes specialist nurse. The primary outcome was the change in length of stay. RESULTS: In total 1837 patients at pre-implementation and 1164 patients at post-implementation undergoing elective surgery were included. Pre- and post-implementation 23.8 % and 33.4 % of patients had day-case surgery respectively. For in-patients median length of stay decreased from 3.2 days (inter-quartile range 1.5-6.1) pre-implementation to 2.5 days (inter-quartile range 1.4-5.4) post-implementation. There were also significant improvements in patient experience, hypo- and hyper-glycaemic events, wound complications and diabetes related complications. CONCLUSIONS: The IP3D intervention has the potential to increase efficiency and reduce waiting lists for elective surgery on a nationwide basis.
