Machine learning identifies the risk of complications after laparoscopic radical gastrectomy for gastric cancer

BACKGROUND Laparoscopic radical gastrectomy is widely used,and perioperative complications have become a highly concerned issue.AIM To develop a predictive model for complications in laparoscopic radical gastrectomy for gastric cancer to better predict the likelihood of complications in gastric cancer patients within 30 days after surgery,guide perioperative treatment strategies for gastric cancer patients,and prevent serious complications.METHODS In total,998 patients who underwent laparoscopic radical gastrectomy for gastric cancer at 16 Chinese medical centers were included in the training group for the complication model,and 398 patients were included in the validation group.The clinicopathological data and 30-d postoperative complications of gastric cancer patients were collected.Three machine learning methods,lasso regression,random forest,and artificial neural networks,were used to construct postoperative complication prediction models for laparoscopic distal gastrectomy and laparoscopic total gastrectomy,and their prediction efficacy and accuracy were evaluated.RESULTS The constructed complication model,particularly the random forest model,could better predict serious complications in gastric cancer patients undergoing laparoscopic radical gastrectomy.It exhibited stable performance in external validation and is worthy of further promotion in more centers.CONCLUSION Using the risk factors identified in multicenter datasets,highly sensitive risk prediction models for complications following laparoscopic radical gastrectomy were established.We hope to facilitate the diagnosis and treatment of preoperative and postoperative decision-making by using these models.

Predicting short-term major postoperative complications in intestinal resection for Crohn’s disease:A machine learning-based study

BACKGROUND Due to the complexity and numerous comorbidities associated with Crohn’s disease(CD),the incidence of postoperative complications is high,significantly impacting the recovery and prognosis of patients.Consequently,additional stu-dies are required to precisely predict short-term major complications following intestinal resection(IR),aiding surgical decision-making and optimizing patient care.AIM To construct novel models based on machine learning(ML)to predict short-term major postoperative complications in patients with CD following IR.METHODS A retrospective analysis was performed on clinical data derived from a patient cohort that underwent IR for CD from January 2017 to December 2022.The study participants were randomly allocated to either a training cohort or a validation cohort.The logistic regression and random forest(RF)were applied to construct models in the training cohort,with model discrimination evaluated using the area under the curves(AUC).The validation cohort assessed the performance of the constructed models.RESULTS Out of the 259 patients encompassed in the study,5.0%encountered major postoperative complications(Clavien-Dindo≥III)within 30 d following IR for CD.The AUC for the logistic model was 0.916,significantly lower than the AUC of 0.965 for the RF model.The logistic model incorporated a preoperative CD activity index(CDAI)of≥220,a diminished preoperative serum albumin level,conversion to laparotomy surgery,and an extended operation time.A nomogram for the logistic model was plotted.Except for the surgical approach,the other three variables ranked among the top four important variables in the novel ML model.CONCLUSION Both the nomogram and RF exhibited good performance in predicting short-term major postoperative complic-ations in patients with CD,with the RF model showing more superiority.A preoperative CDAI of≥220,a di-minished preoperative serum albumin level,and an extended operation time might be the most crucial variables.The findings of this study can assist clinicians in identifying patients at a higher risk for complications and offering personalized perioperative management to enhance patient outcomes.

Prognostic value of ultrasound in early arterial complications post liver transplant

Liver transplantation is the primary therapeutic intervention for end-stage liver disease.However,vascular complications,particularly those involving the hepatic artery,pose significant risks to patients.The clinical manifestations associated with early arterial complications following liver transplantation are often non-specific.Without timely intervention,these complications can result in graft fai-lure or patient mortality.Therefore,early diagnosis and the formulation of an op-timal treatment plan are imperative.Ultrasound examination remains the pre-dominant imaging modality for detecting complications post liver transplan-tation.This article comprehensively reviews common causes and clinical present-ations of early hepatic artery complications in the post-transplantation period and delineates abnormal sonographic findings for accurate diagnosis of these con-ditions.Overall,ultrasound offers the advantages of convenience,safety,effect-iveness,and non-invasiveness.It enables real-time,dynamic,and precise evalua-tion,making it the preferred diagnostic method for post-liver transplantation assessments.INTRODUCTION Liver transplantation stands as the primary therapeutic approach for end-stage liver disease.Continuous advancements in surgical techniques and the application of novel immunosuppressive agents contribute to ongoing improvements in the success rate and overall survival in patients undergoing liver transplantation procedures.Despite these advan-cements,vascular complications,particularly those involving the hepatic artery,pose significant risks to patients.During the early stages following liver transplantation(within the first 30 d),proper hepatic artery function is crucial for hepatic arterial blood flow.During later stages,collateral circulation,including arteries such as the phrenic artery,right gastric artery,and gastroduodenal artery,becomes important for maintaining hepatic blood supply.It is now understood that the establishment of effective collateral circulation is pivotal for determining the prognosis of hepatic artery complic-ations.The clinical manifestations of these complications are closely linked to factors such as timing,severity,and the specific type of onset.Insufficient hepatic arterial blood flow can lead to abnormal liver function,hepatic infarction,and the formation of hepatic abscesses.Additionally,since the hepatic artery is the sole blood supply to the biliary tract,hepatic artery-related ischemia may result in biliary stricture,obstruction,and the formation of bile ducts.Ultrasound examination remains the primary imaging modality for diagnosing complications post liver transplantation.This article comprehensively reviews common causes and clinical presentations of early hepatic artery complications in the post-transplantation period and outlines abnormal sonographic findings for accurately diagnosing these conditions.NORMAL HEPATIC ARTERY During the intraoperative phase,an ultrasound examination is typically conducted to evaluate the hepatic artery anas-tomosis.The normal internal diameter of the hepatic artery typically ranges from 2 to 5 mm.Two strong echo points are typically identified near the anastomosis.To assess blood flow dynamics,peak systolic velocity,end-diastolic velocity,and resistance index are measured at the donor and recipient sides of the anastomosis following angle correction.Anastomotic stenosis presence and severity can be evaluated by comparing the velocity at the anastomotic site with that at the recipient side.Postoperatively,direct visualization of the anastomosis site through gray ultrasound scans is often challenging.The surgical approach has a significant impact on the proper hepatic artery’s position,resulting in a lower overall success rate of continuous visualization.Color Doppler ultrasound is primarily employed to trace the artery’s path,and spectral measurements are taken at the brightest position of the Color Doppler blood flow signal,primarily used to identify the presence of high-speed turbulence.Hepatic artery spectrum examination plays a crucial role,as a favorable arterial spectral waveform and appropriate hepatic artery flow velocity typically indicate a successful anastomosis,even in cases where the hepatic artery anastomosis cannot be directly visualized by ultrasound.The hepatic artery runs alongside the portal vein,often selected as a reference due to its larger inner diameter.A normal hepatic artery spectrum displays a regular pulsation pattern with a rapid rise in systole and a slow decline in diastole.Parameters for assessing hepatic artery resistance include a resistance index between 0.5 to 0.8 and an artery systolic acceleration of less than 80 ms.Instantaneous increases in the resistance index(RI>0.8)often occur within 2 d after surgery,followed by a subsequent return to normal hepatic arterial parameters.It has been established that the maximum blood flow velocity during systole in the hepatic artery should not exceed 200 cm/s[1].

Impact of comorbid subthreshold depressive symptoms on cancerrelated fatigue and complications in adults with leukemia

BACKGROUND Patients not only experience symptoms caused by cancer but also suffer from the accompanying psychological pain.Therefore,these patients do not have high quality of life.According to the World Health Organization,the incidence of leukemia in China in 2020 was 5.1/100000,the mortality rate was 3.3/100000,and the prevalence rate was 16.7/100000.Therefore,it is important to examine the influence of comorbid subthreshold depressive symptoms on leukemia patients.AIM To determine the impact of comorbid subthreshold depressive symptoms on cancer-related fatigue and complications in leukemia patients,thereby providing a basis for early diagnosis and treatment in clinical practice.METHODS A questionnaire survey was conducted among leukemia patients admitted to a tertiary hospital in Xi'an,Shaanxi Province,China,from August 2022 to December 2023.Patients with a score>16 on the Chinese Classification of Mental Disorders(CCMD-3)and a Hamilton Depression Rating Scale score of 8-17 were classified as the subthreshold depressive group(n=95),while 100 leukemia patients admitted during the same period were classified as the control group.Data were collected using Epidata 3.1 software,and comparisons were made between the two groups regarding general clinical data,the Piper Fatigue Scale(PFS),the Pittsburgh Sleep Quality Index(PSQI),the Numeric Rating Scale for pain assessment,laboratory indicators,and the occurrence of complications.RESULTS In this survey,120 leukemia patients with depression were preliminarily screened,95 patients with subthreshold depression were ultimately selected as the subthreshold depression group,and 100 leukemia patients admitted during the same period were enrolled as the normal group.Comparison of basic clinical data between the two groups revealed no significant differences in age,sex,body mass index,cognitive function,or comorbidity with other chronic diseases.However,there were statistically significant differences in the use of radiotherapy and regular exercise between the two groups(P<0.05).Comparisons of scales and laboratory indicators revealed no significant differences in albumin or PSQI scores between the two groups,but there were statistically significant differences in pain scores,PSQI scores,PFS scores,hemoglobin levels,and C-reactive protein levels(P<0.05).Spearman’s correlation analysis indicated that cancer-related fatigue was correlated with age,hemoglobin levels,C-reactive protein levels,pain,and regular exercise among leukemia patients with subthreshold depression.Multivariate regression analysis revealed that advanced age,combined radiotherapy,pain,and low hemoglobin levels were risk factors for cancer-related fatigue in leukemia patients with comorbid subthreshold depression,while regular exercise was a protective factor against cancer-related fatigue.Follow-up comparisons revealed a significantly lower overall incidence of complications in the control group(4%)than in the depressive group(24.21%;P<0.001).CONCLUSION Leukemia patients with comorbid subthreshold depressive symptoms experience more severe cancer-related fatigue and a higher incidence of complications.These findings may be related to advanced age,combined radiotherapy,pain,and low hemoglobin levels,while regular exercise may effectively alleviate symptoms.

Comparison of different preoperative objective nutritional indices for evaluating 30-d mortality and complications after liver transplantation

BACKGROUND The nutritional status is closely related to the prognosis of liver transplant re-cipients,but few studies have reported the role of preoperative objective nutri-tional indices in predicting liver transplant outcomes.AIM To compare the predictive value of various preoperative objective nutritional indicators for determining 30-d mortality and complications following liver transplantation(LT).METHODS A retrospective analysis was conducted on 162 recipients who underwent LT at our institution from December 2019 to June 2022.RESULTS This study identified several independent risk factors associated with 30-d mor-tality,including blood loss,the prognostic nutritional index(PNI),the nutritional risk index(NRI),and the control nutritional status.The 30-d mortality rate was 8.6%.Blood loss,the NRI,and the PNI were found to be independent risk factors for the occurrence of severe postoperative complications.The NRI achieved the highest prediction values for 30-d mortality[area under the curve(AUC)=0.861,P<0.001]and severe complications(AUC=0.643,P=0.011).Compared to those in the high NRI group,the low patients in the NRI group had lower preoperative body mass index and prealbumin and albumin levels,as well as higher alanine aminotransferase and total bilirubin levels,Model for End-stage Liver Disease scores and prothrombin time(P<0.05).Furthermore,the group with a low NRI exhibited significantly greater incidences of intraabdominal bleeding,primary graft nonfunction,and mortality.CONCLUSION The NRI has good predictive value for 30-d mortality and severe complications following LT.The NRI could be an effective tool for transplant surgeons to evaluate perioperative nutritional risk and develop relevant nutritional therapy.

Clinical nursing value of predictive nursing in reducing complications of pregnant women undergoing short-term massive blood transfusion during cesarean section

BACKGROUND Cesarean hemorrhage is one of the serious complications,and short-term massive blood transfusion can easily cause postoperative infection and physical stress response.However,predictive nursing intervention has important clinical significance for it.AIM To explore the effect of predictive nursing intervention on the stress response and complications of women undergoing short-term mass blood transfusion during cesarean section(CS).METHODS A clinical medical record of 100 pregnant women undergoing rapid mass blood transfusion during sections from June 2019 to June 2021.According to the different nursing methods,patients divided into control group(n=50)and observation group(n=50).Among them,the control group implemented routine nursing,and the observation group implemented predictive nursing intervention based on the control group.Moreover,compared the differences in stress res-ponse,complications,and pain scores before and after the nursing of pregnant women undergoing rapid mass blood transfusion during CS.RESULTS The anxiety and depression scores of pregnant women in the two groups were significantly improved after nursing,and the psychological stress response of the observation group was significantly lower than that of the control group(P<0.05).The heart rate and mean arterial pressure(MAP)of the observation group during delivery were lower than those of the control group,and the MAP at the end of delivery was lower than that of the control group(P<0.05).Moreover,different pain scores improved significantly in both groups,with the observation group considerably less than the control group(P<0.05).After nursing,complications such as skin rash,urinary retention,chills,diarrhea,and anaphylactic shock in the observation group were 18%,which significantly higher than in the control group(4%)(P<0.05).CONCLUSION Predictive nursing intervention can effectively relieve the pain,reduce the incidence of complications,improve mood and stress response,and serve as a reference value for the nursing of women undergoing rapid mass transfusion during CS.

Acute worsening of microvascular complications of diabetes mellitus during rapid glycemic control:The pathobiology and therapeutic implications

While chronic hyperglycaemia resulting from poorly controlled diabetes mellitus(DM)is a well-known precursor to complications such as diabetic retinopathy,neuropathy(including autonomic neuropathy),and nephropathy,a paradoxical intensification of these complications can rarely occur with aggressive glycemic management resulting in a rapid reduction of glycated haemoglobin.Although,acute onset or worsening of retinopathy and treatment induced neuropathy of diabetes are more common among these complications,rarely other problems such as albuminuria,diabetic kidney disease,Charcot’s neuroarthropathy,gastroparesis,and urinary bladder dysfunction are also encountered.The World Journal of Diabetes recently published a rare case of all these complications,occurring in a young type 1 diabetic female intensely managed during pregnancy,as a case report by Huret et al.It is essential to have a comprehensive understanding of the pathobiology,prevalence,predisposing factors,and management strategies for acute onset,or worsening of microvascular complications when rapid glycemic control is achieved,which serves to alleviate patient morbidity,enhance disease management compliance,and possibly to avoid medico-legal issues around this rare clinical problem.This editorial delves into the dynamics surrounding the acute exacerbation of microvascular complications in poorly controlled DM during rapid glycaemic control.

Mechanical Complications after Myocardial Infarction: A Comprehensive Review

Mechanical complications of myocardial infarction are potentially fatal events that can occur after an acute myocardial infarction. While the introduction of primary percutaneous reperfusion and fibrinolysis has reduced the incidence of these complications to less than 1%. These complications pose significant hemodynamic consequences and necessitate prompt diagnosis. Echocardiography, cardiac magnetic resonance imaging, and computed tomography are valuable tools for establishing an accurate and expedited diagnosis. Consequently, it is imperative to conduct further scientific research to enhance hemodynamic stabilization techniques such as intra-aortic balloon counterpulsation and extracorporeal membrane oxygenation, in addition to exploring new surgical procedures that can reduce mortality resulting from mechanical complications. This article aims to provide a comprehensive review of mechanical complications following myocardial infarction and their correlation with multi-imaging, facilitating a better understanding of these complications.

Recognizing and preventing complications regarding bioresorbable scaffolds during coronary interventions

The evolution of coronary intervention techniques and equipment has led to more sophisticated procedures for the treatment of highly complex lesions.However,as a result,the risk of complications has increased,which are mostly iatrogenic and often include equipment failure.Stent dislodgement warrants vigilance for the early diagnosis and a stepwise management approach is required to either expand or retrieve the lost stent.In the era of bioresorbable scaffolds that are not radiopaque,increased caution is required.Intravascular imaging may assist in detecting the lost scaffold in cases of no visibility fluoroscopically.Adequate lesion preparation is the key to minimizing the possibility of equipment loss;however,in the case that it occurs,commercially available and improvised devices and techniques may be applied.

Research progress on the correlation between aqueous humor components and pathogenesis and postoperative complications in patients with different types of cataracts

Aqueous humor provides the necessary nutrition for the lens and transports the metabolites in the eye.It was a liquid that can directly reflect the microenvironment in the eye'and it can be easily obtained during the operation.This review intended to analyze the components of aqueous humor in patients with different types of cataracts'so as to reflect the pathogenesis and development of the disease'evaluate the incidence of postoperative complications and provide reference value for the surgical design of sequential cataract surgery.The aqueous humor components of different types of cataracts showed different degrees of inflammation'oxidative stress and extracellular matrix remodeling.The biomarker of early neuropathy in diabetic cataract was neural cell adhesion molecule-1(NCAM1).Transforming growth factor-β(TGF-β)was the evaluation factor of disease development in patients with pseudoexfoliation syndrome.The relationships between postoperative complications of different types of cataracts and aqueous humor components were as follows:Macular edema after diabetic cataract surgery was associated with tumor necrosis factor-alpha;capsular contraction after high myopic cataract surgery was related to monocyte chemoattractant protein-1(MCP-1)and TGF-β2;Klotho and glutathione S-transferase P 1(GSTP1)were associated with high intraocular pressure after primary open-angle glaucoma complicated by cataract surgery;capsular contraction after retinitis pigmentosa complicated by cataract surgery was associated with matrix metalloproteinases;pro-inflammatory cytokines and fibroblast growth factor 4 in the aqueous humor of congenital cataracts were associated with posterior capsular opacification after surgery.Granulocyte colony stimulating factor 3 and MCP-1 were the main cytokines mediating the pain of the second eye in the binocular sequential cataract surgery short interval(1 wk)'while MCP-1 mediated pain in the long interval(6 wk).The second eye after binocular sequential cataract surgery had a higher level of proinflammatory factors.The components of aqueous humor in patients with different types of cataracts were related to the pathogenesis and postoperative complications of the disease.Monitoring the components of the aqueous humor could help better understand the intraocular microenvironment of different types of cataracts and provide a reference for predicting the development of the disease and implementing relevant targeted therapy.

Dear Editor,W e write to present a case report of transepithelial photorefractive keratectomy(TPRK)without mitomycin-C(MMC)for irregular astigmatism after femtosecond laser-assisted in situ keratomileusis(FS-LASIK)flap complications.Written informed consent was obtained from the patient to allow the publication of this case and associated accompanying images.The study was conducted in accordance with the Helsinki Declaration.TPRK is a surgical procedure which uses an excimer laser to ablation of both the corneal epithelium and stroma,which is widely used in clinic[1-2].The procedure may be conducted in cases where there is notable topographic irregularity or scarring following complications with the LASIK flap.Corneal haze is a potential complication following TPRK,and the use of MMC as a prophylactic agent against postoperative corneal haze has been demonstrated to significantly reduce its formation after TPRK/photorefractive keratectomy(PRK).

Tenosynovitis of hand: Causes and complications

Tenosynovitis represents a common clinical condition characterized by inflam-mation of the synovium that encases the tendon sheath.Although tenosynovities may be noted in any tendon in the body,extremities such as hand,and foot remain the sites of high predilection to acquire this condition.The predominant cause of this predilection rests in the intricate tendon arrangements in these extremities that permit fine motor actions.This editorial explores the common causes and the complications associated with this condition to improve the understanding of the readers of this common condition encountered in our everyday clinical practice.

Defining the association between the prolonged operative time and 90-day complications in patients undergoing radical cystectomy

Objective:Radical cystectomy is a complex lengthy procedure associated with postoperative morbidity.We aimed to assess the operative time(OT)in patients undergoing radical cystectomy and its impact on 90-day postoperative complications and readmission rates.Methods:The retrospective cohort study included 296 patients undergoing radical cystectomy and urinary diversion from May 2010 to December 2018 in our institution.The OT of 369 min was set as a cutoff value between short and long OT groups.The primary outcome was 90-day postoperative complication rates.Secondary outcomes were gastrointestinal recovery time,length of hospital stay,and 90-day readmission rates.Results:The overall incidence of 90-day postoperative complications was 79.7%where 43.2%representing low-grade complications according to the ClavieneDindo classification(Grade 1 and Grade 2),and 36.5%representing high-grade complications(Grade3).Gastrointestinal tract and infectious complications are the most common complications in our data set(45.9%and 45.6%,respectively).On multivariable analysis,prolonged OT was significantly associated with odds of high-grade complications(odds ratio 2.340,95%confidence interval 1.288e4.250,p=0.005).After propensity score-matched analysis,a higher incidence of major complications was identified in the long OT group 55(51.4%)compared to 35(32.7%)in the short OT group(p=0.006).A shorter gastrointestinal tract recovery time was noticed in the short OT group(p=0.009).Prolonged OT was associated with a higher 90-day readmission rate on univariate and multivariate analyses(p<0.001,p=0.001,respectively).

Can we predict the incidence of high-grade Clavien-Dindo complications in patients with forgotten encrusted stents undergoing endourologic management?

Objective:Ureteral stents are customarily inserted to facilitate urinary drainage,but they come with their own glitches of being forgotten and/or encrusted leading to serious consequences.The present study aimed to report the complications in patients with forgotten and encrusted stents according to the Clavien-Dindo system specific to urological procedures and identify the factors leading to high-grade(Clavien-Dindo Grade 4A or above)complications.Methods:The hospital records of patients with forgotten encrusted double-J stents over a period of 8 years were reviewed.The parameters recorded included patient demographics,indwelling time,need for percutaneous nephrostomy,hemodialysis,urine culture,blood culture,total blood counts,serum creatinine,radiologic findings,management techniques,number of surgical interventions,modified Clavien-Dindo complications,follow-up,and mortality,if any.Results:Forty patients were included in the study.The median age was 52(range 6-85)years.Of the total,25(62.5%)patients had a“significant”stent load;31(77.5%)had renal failure or acute kidney injury on presentation;19(47.5%)patients had sepsis at presentation.Among the patients presented with sepsis,11(57.9%)patients demonstrated a positive urine culture;and 7/11(63.6%)patients exhibited pan-resistant organisms.Twelve out of 40(30.0%)patients in our series developed high-grade Clavien-Dindo complications.On univariate analysis,sepsis at presentation(p=0.007),stent load(p=0.031),diabetes(p=0.023),positive urine culture(p=0.007),and stent indwelling time of more than 1 year(p=0.031)were found to be significant.On multivariate logistic regression analysis,sepsis at presentation(p=0.017)and positive urine culture(p=0.016)were significant predictors for high-grade complications.Conclusion:It is prudent to identify specific risk factors,namely sepsis at presentation and positive urine culture to triage and optimize these patients before surgical management.

Complications of Corticosteroid Therapy in Rheumatological Practice in Guinea

Introduction: Corticosteroid therapy used in rheumatology is effective but can lead to complications. The objective was to describe the complications of corticosteroid therapy in rheumatological practice at Ignace Deen University Hospital (Conakry). Methods: Cross-sectional study from July 1, 2022 to March 31, 2023. All patients who had been diagnosed with a rheumatological disease and who had received corticosteroid therapy were included. Results: Of the 1489 patients suffering from rheumatological diseases, 238 (15.9%) had received corticosteroid therapy. The average age of the patients was 48.5 ± 17.16 years with a female predominance (70.5%). The main indications for corticosteroid therapy were lower back pain due to probable disco-radicular impingement (35.8%) followed by rheumatoid arthritis (21.9%). The predominant method of administration was infiltration (56.9%). The average dosage was 24.2 ± 13.5 mg prednisone equivalent (range: 5 mg and 40 mg). Complications were present in 26 patients (10.9%) such as muscle cramps (3.8%), hypocalcemia (3.4%), edema of the lower limbs (3%), stimulation of appetite and weight gain (3%), high blood pressure (2.5%), hyperglycemia (2.5%). The occurrence of complications was associated with the high dose of corticosteroid (p = 0.014) and long-term use (p = 0.000). Conclusion: Corticosteroid therapy used in 15.9% of consultations in the rheumatology department of Ignace Deen University Hospital led to 10.9% of complications. These complications were related to the dose and duration of corticosteroid therapy.

Mechanical Complications of Osteosynthesis: Frequency and Management at the Orthopedics-Traumatology Department of CHU Ignace DEEN

Introduction: Mechanical complications after osteosynthesis are spontaneous and harmful modifications of the joint compromising the consolidation process. The aim of this study is to report on the frequency of these complications and their management in the Orthopaedic-Traumatology Department of CHU Ignace Deen. Patients and Methods: we conducted a retrospective descriptive and analytical cross-sectional study from January 2017 to December 2022. It focused on the records of patients hospitalized and treated in the department for a mechanical complication after osteosynthesis. Results: The frequency of mechanical complications was 1.2%, with an average age of 44.2 years and a sex ratio of 3.2 in favor of men. Non-compliance with postoperative instructions, non-compliance with surgical technique, postoperative infection and early loading were the main contributing factors. Disassembly of the screw-plate was the most common cause in 6 cases (35.5%), with a mean delay of 4.1 months. Revision osteosynthesis was carried out using screw plates in 8 cases (47.1%). Conclusion: Mechanical complications of osteosynthesis are less frequent traumatic conditions in our department. Several factors contribute to their occurrence.

Predictors and Complications of Prematurity in Two Health Facilities in Fako Division, Southwest Region, Cameroon

Background: Prematurity is the leading cause of neonatal mortality. Most preterm births can be associated to an identifiable risk factor. In Cameroon, especially in the Southwest Region, there is limited data regarding prematurity associated risk factors. The aim of this study was to evaluate the risk factors and complications of prematurity in two health facilities in the Fako division, the BRH and RHL. Methods: A hospital based retrospective case control study was done from the 1st of January 2021 to 28th of February 2022. We assessed the gestational ages at which preterm birth occurred and their short-term outcome using a structured pretested questionnaire to collect data from files. Data was analyzed using Statistical Package for Social Sciences (SPSS) version 26. Results: The minimum sample size was 137 preterms. 45.5% of cases were born between 34 and increased the risk of having a preterm birth meanwhile being married (AOR: 0.410;95% CI: 0.217 - 0.773;p = 0.006) decreased the risk. Hospital complications were neonatal infection 103 (51.5%), respiratory distress 79 (39.5%) and neonatal jaundice 61 (30.50%). Among the cases, 97 (48.50%) stayed in the hospital for 2 to 4 weeks and 177 (88.5%) were discharged alive. Conclusions: Modifiable factors that increased the risk of prematurity were advanced maternal age, secondary level of education, rural residence, and prenatal alcohol consumption. Being married decreased the risk. The most common hospital complications in both the cases and controls were neonatal infection, respiratory distress syndrome and neonatal jaundice.
