Balancing act: The dilemma of rapid hyperglycemia correction in diabetes management.

The global diabetes surge poses a critical public health challenge, emphasizing the need for effective glycemic control. However, rapid correction of chronic hyperglycemia can unexpectedly trigger microvascular complications, necessitating a reevaluation of the speed and intensity of glycemic correction. Theories suggest swift blood sugar reductions may cause inflammation, oxidative stress, and neurovascular changes, resulting in complications. Healthcare providers should cautiously approach aggressive glycemic control, especially in long-standing, poorly controlled diabetes. Preventing and managing these complications requires a personalized, comprehensive approach with education, monitoring, and interdisciplinary care. Diabetes management must balance short and long-term goals, prioritizing overall well-being. This editorial underscores the need for a personalized, nuanced approach, focusing on equilibrium between glycemic control and avoiding overcorrection.

Effect of Inverse Ratio Ventilation on Respiratory Mechanics and Postoperative Pulmonary Complications in Morbidly Obese Patients Under-going Laparoscopic Sleeve Gastrectomy / 医学研究杂志

Objective To observe the effects of inverse ratio ventilation on respiratory mechanics and postoperative pulmonary com-plications in morbidly obese patients during laparoscopic sleeve gastrectomy Methods A total of 62 morbidly obese patients for a laparo-scopic sleeve gastrectomy were scheduled(18-65 years old,BMI≥35kg/m2 in combination with diabetes,hypertension,hyperlipemia,and other metabolic diseases,or BMI≥40kg/m2,ASA Ⅱ or Ⅲ).Patients were randomly assigned to two groups:inverse ratio ventilation group(IRV)and control group(PVG).Two groups were adjusted with an actual tidal volume(VT)of 7-8ml/kg,and respiratory rates of 12 breaths/min.In the IRV group,the ratio of I∶E was 2∶1;in the control group,the ratio of I∶E was 1∶2.We recorded the indexes of respiratory mechanics and the blood gas at the baseline(T0),5min after anesthesia(T,),15min after pneumoperitoneum(T2),30min after pneumoperitoneum(T3),60min after pneumoperitoneum(T4)and the end of surgery(T5),and the occurrence of pulmonary com-plications on day 1,day 2 after operation was observed,and the cumulative incidence of PPCs at 7 days was counted.Results Compared to the control group,the dynamic lung compliance(Cdyn),mean airway pressure(Pmean),positive end expiratory pressure(PEEP),and the PaO2 at T,-T5 of the inverse ventilation group were increased significantly(P＜0.05),the Ppeak、Pplat at T2-T5 and dynamic lung compliance(VD/VT)at T3-T5 were decreased significantly(P＜0.05),and no difference in the PaCO2 and PETCO2 in the two groups.Grade 1 pulmonary complications occurred in both groups,and there was no difference in the total occurrence of pulmonary com-plications at 7 days.Conclusion Inverse ventilation effectively may improve respiratory mechanics and oxygenation in morbidly obese pa-tients undergoing laparoscopic sleeve gastrectomy.

SARS-CoV-2 infection and diabetes: Pathophysiological mechanism of multi-system organ failure.

Since the discovery of the coronavirus disease 2019 outbreak, a vast majority of studies have been carried out that confirmed the worst outcome of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection in people with preexisting health conditions, including diabetes, obesity, hypertension, cancer, and cardiovascular diseases. Likewise, diabetes itself is one of the leading causes of global public health concerns that impose a heavy global burden on public health as well as socio-economic development. Both diabetes and SARS-CoV-2 infection have their independent ability to induce the pathogenesis and severity of multi-system organ failure, while the co-existence of these two culprits can accelerate the rate of disease progression and magnify the severity of the disease. However, the exact pathophysiology of multi-system organ failure in diabetic patients after SARS-CoV-2 infection is still obscure. This review summarized the organ-specific possible molecular mechanisms of SARS-CoV-2 and diabetes-induced pathophysiology of several diseases of multiple organs, including the lungs, heart, kidneys, brain, eyes, gastrointestinal system, and bones, and sub-sequent manifestation of multi-system organ failure.

(4) Prognosis of patients with periampullary carcinoma. Results of survival analysis of 1 590 patients with main locations of periampullary carcinoma showed that of 1 023 patients with pancreatic cancer, 969 cases were followed up for 3.0-69.6 months, with a median follow-up time of 30.9 months. The median overall survival time, 1-year, 3-year and 5-year survival rates of pancreatic cancer patients were 19.5 months [95% confidence interval ( CI) as 18.0-21.2 months], 74.28%, 29.22% and 17.92%. Of 225 patients with duodenal papillary cancer, 185 cases were followed up for 3.0-68.9 months, with a median follow-up time of 36.7 months. The median overall survival time, 1-year, 3-year and 5-year survival rates were unreached, 94.92%, 78.87% and 66.94%. Of 156 patients with distal bile duct cancer, 110 cases were followed up for 3.0-69.5 months, with a median follow-up time of 25.9 months. The median overall survival time, 1-year, 3-year and 5-year survival rates were 50.6 months (95% CI as 31.4 to not reached), 90.37%, 56.11% and 48.84%. Of 134 patients with ampullary cancer, 100 cases were followed up for 3.0-67.8 months, with a median follow-up time of 28.1 months. The median overall survival time, 1-year, 3-year and 5-year survival rates were 62.4 months (95% CI as 37.8 months to not reached), 90.57%, 64.98% and 62.22%. Of 52 patients with duodenal cancer, 38 cases were followed up for 3.0-69.5 months, with a median follow-up time of 26.2 months. The median overall survival time, 1-year, 3-year and 5-year survival rates were 52.0 months (95% CI as 30.6 months to not reached), 93.75%, 62.24% and 40.01%.There was a significant difference in overall survival after PD between patients with different locations of periampullary malignancies ( χ2=163.76, P<0.05). Conclusions:PD is safe and feasible in a high-volume pancreas center, but the incidence of overall postoperative complications remains high. With the increase of PD volume, the incidence of overall postoperative complications has significantly decreased. There is a significant difference in overall survival time after PD among patients with different locations of periampullary malignancies. The 5-year survival rate after PD for duodenal papillary cancer, ampullary cancer, duodenal cancer and distal bile duct cancer is relatively high, whereas for pancreatic cancer is low.

Objective:To investigate the clinical efficacy of laparoscopic-assisted inters-phincteric resection (ISR) with different surgical approaches for low rectal cancer.Methods:The retrospective cohort study was conducted. The clinicopathological data of 90 patients with low rectal cancer who were admitted to the Second Affiliated Hospital of Fujian Medical University from January 2016 to December 2020 were collected. There were 58 males and 32 females, aged (60±9)years. Of 90 patients, 60 cases underwent laparoscopic assisted ISR with transpelvic approach, 30 cases underwent laparoscopic assisted ISR with transabdominal and transanal mixed approach. Observation indicators: (1) clinicopathological characteristics of patients with transpelvic approach and mixed approach; (2) intraoperative and postoperative conditions of patients with transpelvic approach and mixed approach; (3) postoperative complications of patients with transpelvic approach and mixed approach; (4) follow-up. Follow-up was conducted by telephone interview and outpatient examination once every 3 months within postoperative 3 years, once every six months in the postoperative 3 to 5 years and once a year after postoperative 5 years to detect tumor recurrence and metastasis, and survival of patients.Follow-up was up to March 2021 or patient death. Measurement data with normal distribution were represented as Mean± SD, and the t test was used for comparison between groups. Measurement data with skewed distribution were expressed as M(range), and comparison between groups was conducted using the non-parametric Mann-Whitney U test. Count data were expressed as absolute numbers or percentages, and comparison between groups was performed using the chi-square test or Fisher exact probability. Comparison of ordinal data was analyzed by the non-parametric rank sum test. Kaplan-Meier method was used to draw survival curves and calculate survival rates, and survival analysis was performed by the Log-Rank test. Results:(1) Clinicopathological characteristics of patients with transpelvic approach and mixed approach. The sex (males, females), distance from the distal margin of tumor to anal margin were 34, 26, (4.5±0.5)cm for patients with transpelvic approach, versus 24, 6, (3.5±0.5)cm for patients with mixed approach, respectively, showing significant differences between them ( χ2=4.75, t=8.35, P<0.05). (2) Intraoperative and postoperative conditions of patients with transpelvic approach and mixed approach. The operation time, volume of intraoperative blood loss, distance from the postoperative anastomosis to anal margin were (187±9)minutes, 50(range, 20?200)mL, (3.4±0.7)cm for patients with transpelvic approach, versus (256±12)minuets, 100(range, 20?200)mL, (2.6±0.7)cm for patients with mixed approach, showing significant differences between them ( t=?26.99, Z=?2.48, t=4.67, P<0.05). None of the 90 patients had a positive distal margin. The stoma reversal rates of patients with transpelvic and mixed approach were 93.3%(56/60) and 90.0%(27/30), respectively. Of the 60 patients with transpelvic approach, 3 cases had no stoma reversal due to anastomotic complications, and 1 case was not yet to the reversal time. Of the 30 patients with mixed approach, 2 cases had no stoma reversal due to anastomotic complications, and 1 case was not yet to the reversal time. The 1-, 3-month Wexner scores after stoma reversal were 15(range, 12?17), 12(range, 10?14) for patients with transpelvic approach, versus 16(range, 14?18), 14(range, 12?16) for patients with mixed approach, showing significant differences between them ( Z=?4.97, ?5.49, P<0.05). The 6-month Wexner score after stoma reversal was 10(range, 9?12) for patients with transpelvic approach, versus 11(range, 8?12) for patients with mixed approach, showing no significant difference between them ( Z=?1.59, P>0.05). (3) Postoperative complications of patients with transpelvic approach and mixed approach. The complications occurred to 16 patients with transpelvic approach and 9 patients with mixed approach, respectively, showing no significant difference between them ( χ2=0.11, P>0.05). Cases with postoperative anastomotic fistula, cases with anastomotic bleeding, cases with anastomotic stenosis, cases with intestinal obstruction, cases with incision infection, cases with urinary retention, cases with pelvic infection, cases with pulmonary infection, cases with incisional hernia, cases with chylous fistula, cases with abdominal and pelvic abscess were 5, 2, 1, 7, 0, 1, 5, 3, 1, 1, 1 for patients with transpelvic approach, versus 6, 3, 2, 2, 2, 1, 2, 3, 1, 1, 1 for patients with mixed approach, showing no significant difference between them ( P>0.05). The same patient could have multiple postoperative complications. (4) Follow-up. All the 90 patients were followed up for 27(range, 6?62)months. The follow-up time of 60 patients with transpelvic approach was 27(range, 8?62)months. The follow-up time of 30 patients with mixed approach was 28(range, 6?53)months. Of the 60 patients with transpelvic approach, 3 cases had local recurrence, 4 cases had liver metastasis, 3 cases had lung metastasis, and all of them survived with tumor. Of the 30 patients with mixed approach, 1 case had local recurrence, 2 cases had liver metastasis, 1 case had lung metastasis, and all of them survived with tumor. There was no death. The 3-year disease-free survival rates of patients with transpelvic approach and mixed approach were 84.7% and 87.9%, respectively, showing no significant difference between them ( χ2=0.39, P>0.05). Conclusions:Lapa-roscopic assisted ISR via transpelvic approach or mixed approach for low rectal cancer are safe and feasible. Compared with transanal mixed approach, the transpelvic approach of laparoscopic-assisted ISR has shorter operation time, less volume of intraoperative blood loss and longer distance from the postoperative anastomosis to anal margin.

Objective To investigate the management and outcome of cerebrospinal fluid leakage(CSFL)complicating anterior cervical surgery.Methods1052patients were performed anterior cervical surgery between October1997and October2002.Of 1052cases,926cases were of cervical spondylotic myelopathy(CSM),and126of ossification of posterior longitudinal ligament (OPLL).11patients suffered from cerebrospinal fluid leakage during operation.There were8males and3females aging from46to72years(average,58years).In the group of CSM,there were2cases of CSFL(0.22%)occurred in resection of osteophyte of the posterior vertebral edge,who were serious CSM of C 4,5 and C 5,6 with severe anterior compression by osseous mass to spinal cord showed on MRI.In the group of OPLL,there were9cases of CSFL(7.14%)occurred in resection of the ossified posterior longitudinal ligament accompanied with severe spinal canal stenosis and anterior compression to spinal cord on radiological imagings,4of them were con-tinuous OPLL from C 2 to C 6 combined with herniation of cervical disc,3segmental,and2mixed.Results The defect area of spinal dura were(0.6～2.0)cm?(1.0～1.5)cm.The cerebrospinal fluid was blocked with fascia and absorbable gelatin sponge during the operation.If CSFL was persistent more than3days after oper-ation,expectant treatment was performed.After the operation,no CSFL occurred in8of 11patients,and the other3cases with postoperative CSFL were cured5,14and17days by dressing change,blocking the wound with gelatin sponge,and suturing of the wound respectively.All patients were followed up for 10to62months(mean,26months).No cerebrospinal fluid cyst and infection occurred.There were no significant negative effects of CSFL on the recovery of neuromuscular function.Conclusion CSFL following cervical anterior surgery can be cured by blocking up leakage of spinal dura during operation,however,conventional conservative treatment including of dressing change,antibiotics administration,horizontal position with low pillow are necessary after operation.

Preventionand management of complications in anterior cervical spine surgery / 中华骨科杂志

Objective To study the prevention and treatment of complications occurring in anterior cervical spinal surgery.Methods3163cases with cervical spondylotic meylopathy,spinal injury,spinal tu-mor and spinal tuberculosis treated by anterior cervical surgery,were included in this study.Trephination,corpectomy,disectomy and debridement were used for decompression,iliac bone autograft,BAK cage,cubic shaped cages and titanium mesh cages were used for bone grafting,while anterior cervical spine locking plates were performed in some of the cases.1848cases were followed-up from6months to8years with an aver-age of 2years and3months.646cases suffered from operative complications,372cases were immediate due to anterior cervical surgery,and the incidence of morbidity was11.76%.Results26cases of transient laryn-geal nerve or superior laryngeal nerve injury recovered in4to12weeks without special treatment.Most of 16cases with cervical hemotoma were caused by bleeding of smaller blood vessels and obstruction of drainage.13cases of spinal cord or nerve root irritation or injury were treated with medicine for dehydration,12of them had good result.11cases of CSF leakage were cured with cervical spinal immobilization and moderate local compression.8cases of local infection were cured with antibiotics or combined with debride-ment and suturing.2cases of esophagus perforation were repaired and healed.8cases of grafted bone dis-placement were re-operated on the day or second day of occurring.17cases of pseudoarthritis had revision surgery.6of 35cases of adjacent segments degeneration with new symptoms of spinal cord compression were treated with anterior cervical decompression again,and had good results.Most of 342cases of iliac donor side com plications were local pain or lateral femoral cutaneous nerve injury,infection occurred in some cases.Compli cations related to instruments included10cases of BAK subsidence,1case of plate breakage,1case of screws and plate back-out and7cases of titanium mesh cage subsidence.216cases of cervical axial pain were cured3to6months later with medicine.There was1case of sudden death in this group.Conclusion Many kinds of operative complications could occur in anterior cervical surgery.A standardized procedure in diagnosis and surgery methods are the key points to decrease and prevent operative related complications.
