Low Prognostic Nutritional Index Predicts In-Hospital Complications and Case Fatality in Patients with Spontaneous Intracerebral Hemorrhage: A Retrospective Study.

Spontaneous intracerebral hemorrhage (ICH) is associated with high case fatality and significant healthcare costs. Recent studies emphasize the critical role of nutritional status in affecting outcomes in neurological disorders. This study investigates the relationship between the Prognostic Nutrition Index (PNI) and in-hospital complications and case fatality among patients with ICH. A retrospective analysis was performed using data from the Changhua Christian Hospital Clinical Research Database between January 2015 and December 2022. Patients under 20 or over 100 years of age or with incomplete medical data were excluded. We utilized restricted cubic spline models, Kaplan-Meier survival analysis, and ROC analysis to assess the association between PNI and clinical outcomes. Propensity score matching analysis was performed to balance these clinical variables between groups. In this study, 2402 patients with spontaneous ICH were assessed using the median PNI value of 42.77. The cohort was evenly divided between low and high PNI groups, predominantly male (59.1%), with an average age of 64 years. Patients with lower PNI scores at admission had higher in-hospital complications and increased 28- and 90-day case fatality rates. Our study suggests that PNI could serve as a valuable marker for predicting medical complications and case fatality in patients with spontaneous ICH.

Electroencephalography-Guided Anesthesia and Delirium in Older Adults After Cardiac Surgery

Intraoperative electroencephalogram (EEG) waveform suppression, suggesting excessive general anesthesia, has been associated with postoperative delirium. To assess whether EEG-guided anesthesia decreases the incidence of delirium after cardiac surgery. Randomized, parallel-group clinical trial of 1140 adults 60 years or older undergoing cardiac surgery at 4 Canadian hospitals. Recruitment was from December 2016 to February 2022, with follow-up until February 2023. Patients were randomized in a 1:1 ratio (stratified by hospital) to receive EEG-guided anesthesia (n = 567) or usual care (n = 573). Patients and those assessing outcomes were blinded to group assignment. The primary outcome was delirium during postoperative days 1 through 5. Intraoperative measures included anesthetic concentration and EEG suppression time. Secondary outcomes included intensive care and hospital length of stay. Serious adverse events included intraoperative awareness, medical complications, and 30-day mortality. Of 1140 randomized patients (median [IQR] age, 70 [65-75] years; 282 [24.7%] women), 1131 (99.2%) were assessed for the primary outcome. Delirium during postoperative days 1 to 5 occurred in 102 of 562 patients (18.15%) in the EEG-guided group and 103 of 569 patients (18.10%) in the usual care group (difference, 0.05% [95% CI, -4.57% to 4.67%]). In the EEG-guided group compared with the usual care group, the median volatile anesthetic minimum alveolar concentration was 0.14 (95% CI, 0.15 to 0.13) lower (0.66 vs 0.80) and there was a 7.7-minute (95% CI, 10.6 to 4.7) decrease in the median total time spent with EEG suppression (4.0 vs 11.7 min). There were no significant differences between groups in median length of intensive care unit (difference, 0 days [95% CI, -0.31 to 0.31]) or hospital stay (difference, 0 days [95% CI, -0.94 to 0.94]). No patients reported intraoperative awareness. Medical complications occurred in 64 of 567 patients (11.3%) in the EEG-guided group and 73 of 573 (12.7%) in the usual care group. Thirty-day mortality occurred in 8 of 567 patients (1.4%) in the EEG-guided group and 13 of 573 (2.3%) in the usual care group. Among older adults undergoing cardiac surgery, EEG-guided anesthetic administration to minimize EEG suppression, compared with usual care, did not decrease the incidence of postoperative delirium. This finding does not support EEG-guided anesthesia for this indication. ClinicalTrials.gov Identifier: NCT02692300.

Evaluation of the Effects of Epidural Labour Analgesia on Mode of Delivery in 250 Bedded District Hospital, Bagerhat, Bangladesh

Background: Labor pain is intensely severe, often leading to hyperventilation and hormonal releases that can harm the fetus by reducing oxygen supply and causing metabolic acidosis. Effective pain management during childbirth is crucial for both physical and mental health. Various pharmacologic and non-pharmacologic methods are available, with epidural analgesia being a prominent choice. It is widely used in high-income countries, provides substantial pain relief, and benefits uterine contractions and placental perfusion. Epidural analgesia has potential side effects and controversies, such as delayed labor and higher intervention rates. Aim of the Study: The study aimed to examine the impact of epidural analgesia on the mode of delivery. Methods: This observational study, conducted from July 2021 to June 2022 at the Department of Gynecology and Obstetrics in a 250-bed District Hospital in Bagerhat, Bangladesh, included 50 participants divided into two groups of 25 each: Group A (with epidural analgesia) and Group B (without epidural analgesia). Approved by the Ethical Committee, the study included women aged 18-35 years, 37-41 weeks gestation, in labor with regular contractions, at least 4 cm cervical dilatation, and a regular fetal heart rate pattern. Excluded were women with medical or obstetrical complications, uterine scars, or spinal deformities. Data were collected via interviews, observations, and clinical examinations. Result: In this study of 50 participants (25 per group), most women were under 30 years old, with mean ages of 22.4±4.5 and 22.9±5.2 years in groups A and B, respectively. Gestational ages ranged from 37 to 40 weeks, and BMIs were 18.5-24.9 kg/m². Both groups had similar parity distributions. Normal vaginal births occurred in 84% (Group A) and 88% (Group B), with LSCS rates at 4%. Group A had 60% male neonates with average birth weights of 2.86±0.27 kg, and Group B had 56% males with weights of 2.88±0.26 kg. APGAR scores were high in both groups. Conclusion: Epidural labor analgesia is safe and does not increase instrumental deliveries or affect neonatal outcomes, making it a viable pain management option. Obstetric care providers can use this information to counsel women.

Failure of Pavlik Harness Treatment in Infants Under 6 Months Old with Dislocated Hips: Short- and Intermediate-Term Results of Subsequent Treatment Modalities

ObjectiveThis study aimed to determine the short- and medium-term outcomes of hip dislocation in infants who failed Pavlik harness therapy and were subsequently treated with brace, closed reduction (CR) or open reduction (OR) before 6 months of age.MethodsFifty infants (66 hip dislocations) who failed Pavlik harness therapy between 2000 and 2018 and were treated with a rigid abduction brace or undergoing a CR or OR/cast were evaluated. All demographic data obtained from the medical system, developments and complications during the follow-up and treatment process were recorded and evaluated.ResultsFifty infants (66 hips) with dislocated hips failed Pavlik harness therapy. Of these, 9 infants (12 hips) underwent rigid abduction splint therapy: 9 hips were successful, 2 hips had CR and 1 had OR. Thirty-eight infants (51 hips) had index CR, of which 3 (3 hips) failed and had OR. Radiographs of 49 hips (44 patients) were normal at the final evaluation. Pavlik harness therapy starting after 3 weeks (P = 0.028) and unilateral dislocations (P = 0.028) increased the risk of needing operating room. There was an association between OR and avascular necrosis (P = 0.025), but not between OR and other complications—dysplasia and re-dislocation/subluxation (P = 0.257 and P = 0.508, respectively).ConclusionClosed treatment of hip dislocation is possible in most babies who fail Pavlik treatment. Babies who are started on Pavlik therapy after 3 weeks of age may be at increased risk of needing an operating room.Level of EvidenceIV.

The impact of a reproductive health voucher in Uganda using a quasi-experimental matching design

This study assesses the impact of a voucher project that targeted vulnerable and poor pregnant women in Uganda. Highly subsidised vouchers gave access to a package of safe delivery services consisting of four antenatal visits, safe delivery, one postnatal visit, the treatment and management of selected pregnancy-related medical conditions and complications, and emergency transport. Vouchers were sold during the project’s operational period from 2016 to 2019. This study covers 8 out of 25 project-benefiting districts in Uganda and a total of 1,881 pregnancies, including both beneficiary and non-beneficiary mothers. Using a matching design, the results show a positive effect on the survival of new-born babies. The difference in the survival rate between the control group and the treatment group is 5.4% points, indicating that the voucher project reduced infant mortality by more than 65 per cent.

The impact of prior ACL reconstruction on total knee arthroplasty outcomes: a retrospective matched cohort study.

Discrepant data exists regarding the outcomes following total knee arthroplasty (TKA) with a prior anterior cruciate reconstruction (ACLR). The purpose of our study was to compare surgical and medical outcomes in the patients with prior ACLR undergoing TKAs compared to a matched control group of the patients who had undergone TKAs without prior ACLR. We hypothesized that the patients with prior ACLR would have inferior clinical outcomes. We retrospectively queried the PearlDiver-database for patients who underwent TKA following ACLR from 2011 to 2020. We used propensity-score matching to create two cohorts. The two-sided independent t-test and Chi-Squared test were used. We identified 2,174 patients who had prior ACLR before the TKAs. There were another 1,348,870 patients who did not have ACLR before the TKAs. After matching, each group had 2,171 patients. The ACLR-TKA group had significantly lower rates of aseptic revision at 2 years (1.2% vs. 4.0%, OR 0.3, p < 0.01), PJI requiring antibiotic spacer at 2 years (0.3% vs. 0.8%, OR 0.35, p = 0.02), and MUA at 90 days (0.4% vs. 7.5%, OR 0.05, p < 0.01). The rate of wound disruption was lower for the ACLR-TKA group at 90 days (p = 0.03) as were several medical complications including AKI at 90 days (p < 0.01), DVT at 90 days (p < 0.01), pneumonia at 90 days (0.04), and required blood transfusion at 90 days (p < 0.01). These results differed from our expectations. Within the limitations of the study, we are unable to determine the factors for the lower complications in the ACLR-TKA group. The data from this study are different from what had been reported in the previous studies.

Is the level of consent to a national research registry associated with patient outcomes following traumatic spinal cord injury? A population-based study from the Rick Hansen Spinal Cord Injury Registry (RHSCIR).

We examined the impact of consenting to the Rick Hansen Spinal Cord Injury Registry (RHSCIR) on outcomes: acute length of stay (LOS), in-hospital mortality, medical complications (pressure injuries and pneumonia), and the final discharge destination following a spinal cord injury (SCI) using the national RHSCIR dataset. A retrospective cohort study was conducted using RHSCIR participant data from 2014 to 2019. Participants approached for enrollment were grouped into 1) PC: provided full consent including community follow-up (CFU) interviews, 2) DWC: declined CFU interviews but accepted minimal data collection that may include initial/final interviews and/or those who later withdrew consent, and 3) DC: declined consent to any participation. As no data was collected for the DC group, descriptive, bivariate, and multivariable regression analysis was limited to the PC and DWC groups. Of 2811 participants, 2101 (74.7%) were PC, 553 (19.7%) were DWC, and 157 (5.6%) were DC. DWC participants had significantly longer acute LOS, more acute pneumonias/pressure injuries, and were less likely to be discharged home than PC participants. All these associations - except pneumonia - remained significant in the multivariable analyses. Not participating fully in RHSCIR was associated with more complications and longer hospital stays.

Identifying Independent Predictors of Short-Term Postoperative Morbidity in Patients Undergoing Cranioplasty.

The present study intends to identify independent predictors of short-term postoperative complications and health utilization in patients undergoing cranioplasty. Demographic, clinical, and intraoperative characteristics were collected for each patient undergoing cranioplasty in the National Surgery Quality Improvement Program database from 2011 to 2020. The 30-day outcomes analyzed were medical complications, wound complications, return to the operating room, extended hospital stay, and non-home discharge. Bivariate analyses were initially used to identify variables that yielded a P value less than 0.2 which were subsequently analyzed in a multivariate logistic regression to identify independent predictors of the aforementioned outcomes. In total, 2316 patients undergoing cranioplasty were included in the analysis. Increased operative time and totally dependent functional status significantly increased odds of returning to the operating room. Increased age, operative time, cranioplasty size >5cm, and various comorbidities were associated with increased odds of non-home discharge. Bleeding disorders were independently associated with increased odds of wound complications. Increased age, operative time, cranioplasty size >5cm, and several medical history features predisposed to medical complications. Demographic characteristics, including age and race, along with various operative and medical history characteristics were associated with increased odds of extended length of stay. Identification of risk factors can help guide preoperative risk management in cranioplasty.

Insulin dependence negatively impacts outcomes in anterior cervical discectomy with fusions: a 10-year retrospective analysis

BACKGROUND CONTEXTAlthough anterior cervical discectomy and fusion (ACDF) procedures for cervical spine disease have been increasing amid a growing diabetic patient population, there is a paucity of literature focusing on insulin-dependence as a risk-factor for postoperative ACDF complications. PURPOSETo evaluate the differential impact of insulin dependence on perioperative outcomes including total length of stay, surgical, and medical complications within thirty days following ACDF. STUDY DESIGN/SETTINGA retrospective cohort, large multicenter database study. PATIENT SAMPLEThe American College of Surgeons National Surgical Quality Improvement Program database was queried to retrospectively identify patients who had undergone ACDF between 2011 and 2021 using the Current Procedural Terminology code 22551. OUTCOME MEASURESPerioperative surgical and medical complications. METHODSThe study population was divided into 3 groups 1) insulin-dependent diabetes mellitus (IDDM), 2) noninsulin-dependent diabetes mellitus (NIDDM), and 3) no diabetes mellitus (non-DM). One-way analysis of variance for continuous variables and chi-square tests for categorical variables were used to identify differences in perioperative variables between the 3 groups. Multivariable logistic regression analysis assessed the effect of diabetes mellitus status on postoperative medical and surgical outcomes. RESULTSA total of 85,758 ACDF procedures were identified between 2011 and 2021, of which 5,178 were IDDM, 9,652 were NIDDM, and 70,982 were non-DM. The rates of surgical and medical complication varied between the 3 groups. IDDM patients had the highest rates of at least one medical complication (6.1%). Only IDDM increased the risk for medical complications (OR: 1.320, 95% CI [1.144–1.518]) and extended hospital length of stay (LOS) (OR: 1.244, 95% CI [1.071–1.441]) following a multivariate logistic regression analysis. CONCLUSIONPatients with IDDM were at an increased risk for postoperative medical complications and extended hospital LOS. Personalized postoperative management, guided by risk assessment is indicated for this population. These findings can be used to improve risk stratification and informed consent for DM patients who are insulin dependent.

Short-Term Morbidity and Mortality after Distal Femur Open Reduction Internal Fixation in the Geriatric Population.

Distal femur fractures remain a significant cause of morbidity and mortality for elderly patients. There is a lack of large population studies investigating short-term outcomes after distal femur c in elderly patients. The purpose of this study is to assess the incidence of and risk factors for various short-term outcomes after distal femur open reduction internal fixation (ORIF) in the geriatric population. The American College of Surgeons' National Surgical Quality Improvement Program (NSQIP) database was used to identify all primary distal femur ORIF cases in patients 60+ years old between January 1, 2015 and December 31, 2020 using Current Procedural Terminology (CPT) codes 27511, 27513, and 27514. Demographic, medical, and surgical variables were extracted for all patients. Propensity score matching was used to match cases in the two age groups based on various demographic and medical comorbidity variables. Several 30-day outcome measures were compared between the 60-79-year-old and 80+-year-old groups both before and after matching. Subsequent multivariate logistic regression was used to identify independent risk factors for 30-day outcome measures in the matched cohort. A total of 2913 patients were included in the final cohort: 1711 patients in the 60-79-year-old group and 1202 patients in the 80+-year-old group. Most patients were female (n = 2385; 81.9%). Prior to matching, the older group had a higher incidence of 30-day mortality (1.9% vs. 6.2%), readmission (3.7% vs. 9.7%, p = 0.024), and non-home discharge (74.3% vs. 89.5%, p < 0.001). Additionally, the older group had a higher rate of blood loss requiring transfusion (30.9% vs. 42.3%, p < 0.001) and medical complications (10.4% vs. 16.4%, p < 0.001), including myocardial infarction (0.7% vs. 2.7%, p < 0.001), pneumonia (2.7% vs. 4.6%, p = 0.008), and urinary tract infection (4.1% vs. 6.1%, p = 0.0188). After matching, the older group consistently had a higher incidence of mortality, non-home-discharge, blood loss requiring transfusion, and myocardial infarction. Various independent risk factors were identified for 30-day morbidity and mortality, including American Society of Anesthesiologists (ASA) classification, body mass index (BMI) status, operative duration, and certain medical comorbidities. Geriatric patients undergoing distal femur ORIF are at significant risk for 30-day morbidity and mortality. After matching, octogenarians and older patients specifically are at increased risk for mortality, non-home discharge, and surgical complications compared to patients aged 60-79 years old. Multiple factors, such as BMI status, ASA classification, operative time, and certain medical comorbidities, are independently associated with poor 30-day outcomes.

Osteotomy Site Venting Enhances Femoral Bone Consolidation With Magnetic Intramedullary Lengthening Nails.

Magnetic intramedullary lengthening nailing has demonstrated benefits over external fixation devices for femoral bone lengthening. These include avoiding uncomfortable external fixation and associated pin site infections, scarring, and inhibition of muscle or joint function. Despite this, little has changed in the field of biologically enhanced bone regeneration. Venting the femoral intramedullary canal at the osteotomy site before reaming creates egress for bone marrow during reaming. The reamings that are extruded from vent holes may function as a prepositioned bone graft at the distraction gap. The relationship between venting and the consolidation of regenerating bone remains unclear. (1) Do bone marrow reamings extruded through venting holes enhance the quality of bone regeneration and improve healing indices and consolidation times? (2) Is venting associated with a higher proportion of complications than nonventing? We performed a retrospective study of femoral lengthening performed at one hospital from December 2012 to February 2022 using a magnetic intramedullary lengthening nail with or without venting at the osteotomy site before reaming. This was a generally sequential series, in which the study groups were assembled as follows: Venting was performed between July 2012 and August 2016 and again from November 2021 onward. Nonventing was used between October 2016 and October 2021 because the senior author opted to create drill holes after the reaming procedure to avoid commitment to the osteotomy level before completing the reaming procedure. Outcomes were evaluated based on bone healing time, time to achieve full weightbearing, and complications. Sixty-one femoral lengthening procedures were studied (in 33 male and 28 female patients); two patients were excluded because of implant breakage. The mean age was 17 ± 5 years. The mean amount of lengthening was 55 ± 13 mm in the venting group and 48 ± 16 mm in the nonventing group (mean difference 7 ± 21 [95% CI 2 to 12]; p = 0.07). The healing index was defined as the time (in days) required for three cortices to bridge with new bone formation divided by the length (in cm) lengthened during the clinical protocol. This index signifies the bone formation rate achieved under the specific conditions of the protocol. Full weightbearing was allowed upon bridging the regenerated gap on three sides. Consolidation time was defined as the total number of days from the completion of the lengthening phase until adequate bone union (all three cortices healed) was achieved and full weightbearing was permitted. This time frame represents the entire healing process after the lengthening is complete divided by the amount of lengthening achieved (in cm). Patient follow-up was conducted meticulously at our institution, and we adhered to a precise schedule, occurring every 2 weeks during the distraction phase and every 4 weeks during the consolidation phase. There were no instances of loss to follow-up. Every patient completed the treatment successfully, reaching the specified milestones of weightbearing and achieving three cortexes of bone bridging. The mean healing index time in the venting group was faster than that in the nonventing group (21 ± 6 days/cm versus 31 ± 22 days/cm, mean difference 10 ± 23 [95% CI 4 to 16]; p = 0.02). The mean consolidation time was faster in the venting group than the nonventing group (10 ± 6 days/cm versus 20 ± 22 days/cm; mean difference 10 ± 23 [95% CI 4 to 15]; p = 0.02). No medical complications such as deep vein thrombosis or fat or pulmonary embolism were seen. Two patients had lengthy delays in regenerate union, both of whom were in the nonventing group (healing indexes were 74 and 62 days/cm; consolidation time was 52 and 40 days/cm). Femoral lengthening with a magnetic intramedullary lengthening nail healed more quickly with prereaming venting than with nonventing, and it allowed earlier full weightbearing without any major associated complications. Future studies should evaluate whether there is a correlation between the number of venting holes and improvement in the healing index and consolidation time. Level III, therapeutic study.

Effect of Obesity on Short- and Long-Term Complications After Ankle Fracture Fixation.

This study evaluated the relationship between obesity and postoperative complications in patients undergoing ankle open reduction internal fixation (ORIF). Retrospective cohort study. PearlDiver-Mariner All-Payor Database. Patients who underwent ankle ORIF from 2010 to 2021 and had a minimum of 2 years of follow-up were identified using Current Procedural Terminology, ICD-9, and ICD-10 codes. Patients were stratified by body mass index into nonobese, obese, morbidly obese, and super-obese groups. Complication rates, including 90-day readmissions, infection, and post-traumatic osteoarthritis, were compared between obesity groups. Patients were additionally compared with a 1:1 matched analysis that controlled for demographics and comorbidities. A total of 160,415 patients undergoing ankle ORIF from 2010 to 2021 were identified. The cohort consisted mostly of females (64.8%) and the average age was 52.5 (SD 18.4) years. There were higher rates of 90-day readmissions, UTIs, DVT/PE, pneumonia, superficial infections, and acute kidney injuries in patients with increasing levels of obesity (P < 0.001). There were increased odds of nonunion and post-traumatic arthritis in the matched analysis at 2 years in the obesity group [OR: 2.36, 95% confidence interval (CI): 1.68-3.31, P < 0.001; OR: 2.18, 95% CI: 1.77-2.68, P < 0.001, respectively]. Postoperative medical complication rates in patients undergoing ankle ORIF, including infection, are higher in obese patients, even in the 1:1 matched analysis that controlled for demographic and comorbidity factors. Rates of nonunion and post-traumatic arthritis were higher in obese patients, as well. As such, it is important for surgeons to provide appropriate education regarding the risks after ankle ORIF in patients with obesity. Prognostic Level III.

Increased Risk of Postoperative Complications in Patients Who Have Obstructive Sleep Apnea Undergoing Total Joint Arthroplasty: A Systematic Review and Meta-Analysis

BackgroundObstructive sleep apnea (OSA) has been linked to multiple adverse health outcomes and postoperative complications. Despite the high prevalence of OSA in patients undergoing total joint arthroplasty (TJA), few studies have evaluated the postoperative course of OSA patients after joint arthroplasty surgery. MethodsPubMed (MEDLINE) and Scopus (EMBASE, MEDLINE, and COMPENDEX) were used to conduct a systematic review of articles from inception to July 2023. Primary studies comparing postoperative outcomes following TJA between patients who had and did not have OSA were included. Postoperative medical complications, utilization of critical care, hospital stay, and mortality data were extracted. Descriptive statistics and random-effects meta-analysis models were used to analyze the available data. Included studies were evaluated for methodological risks of bias using the risk of bias in non-randomized studies of interventions. This review was registered on the International Prospective Register of Systematic Reviews (ID: CRD42023447610). ResultsThere were 7 studies with a total of 20,977 patients (9,425 hip; 11,137 knee; 415 hip or knee) that were included. Pulmonary complications were most frequently studied, followed by thromboembolic events. Cardiac, gastrointestinal, hematologic, genitourinary, and delirium events were also reported across studies. Meta-analysis revealed that OSA patients had 4-fold increased odds of overall medical complications (OR [odds ratio], 4.23; 95% confidence interval (CI), 2.97 to 6.04; P < .001; I2 = 0%), 4-fold increased odds of pulmonary complications (OR, 4.31; 95% CI, 2.82 to 6.60; P < .001; I2 = 0%), 2-fold increased odds of thromboembolic complications (OR, 1.92; 95% CI, 1.22 to 3.03; P = .005; I2 = 9%), and 4-fold increased odds of delirium (OR, 3.94; 95% CI, 1.72 to 9.04; P = .001; I2 = 0%). ConclusionsA significant association was found between OSA and overall medical, pulmonary, and thromboembolic complications. These patients also had a higher incidence of postoperative delirium. The present findings underscore the need for comprehensive perioperative strategies to mitigate these risks in OSA patients who elect to undergo TJA.

Super-Obesity is Associated With an Increased Risk of Complications Following Primary Total Knee Arthroplasty

BackgroundObesity, defined as a body mass index (BMI) ≥ 30, is an ever-growing epidemic, with > 35% of adults in the United States currently classified as obese. Super-obese individuals, defined as those who have a BMI ≥ 50, are the fastest-growing portion of this group. This study sought to quantify the infection risk as well as the incidence of surgical, medical, and thromboembolic complications among super-obese patients undergoing total knee arthroplasty (TKA). MethodsAn all-payer claims database was used to identify patients who underwent elective, primary TKA between 2016 and 2021. Patients who had a BMI ≥ 50 were compared to those who had a normal BMI of 18 to 25. Demographics and the incidence of 90-days postoperative complications were compared between the 2 groups. Univariate analysis and multivariable regression were used to assess differences between groups. ResultsIn total, 3,376 super-obese TKA patients were identified and compared to 17,659 patients who had a normal BMI. Multivariable analysis indicated that the super-obese cohort was at an increased postoperative risk of periprosthetic joint infection (adjusted odds ratio [aOR] 3.7, 95% confidence interval [CI]: 2.1 to 6.4, P < .001), pulmonary embolism (aOR 2.2, 95%-CI: 1.0 to 5.0, P = .047), acute respiratory failure (aOR 4.1, 95%-CI: 2.7 to 6.1, P < .001), myocardial infarction (aOR 2.5, 95%-CI: 1.1 to 5.8, P = .026), wound dehiscence (aOR 2.3, 95%-CI: 1.4 to 3.8, P = .001), and acute renal failure (aOR 3.2, 95%-CI: 2.4 to 4.2, P < .001) relative to patients who have normal BMI. ConclusionsSuper-obese TKA patients are at an elevated risk of postoperative infectious, surgical, medical, and thromboembolic complications. As such, risk stratification, as well as appropriate medical management and optimization, is of utmost importance for this high-risk group.

Short-term outcomes of early intensive neurorehabilitation for prolonged disorders of consciousness: A prospective cohort study

BackgroundAdvances in medical care have increased survival in people with severe brain injuries and with that the number of survivors with prolonged disorders of consciousness (PDOC) has increased. In the literature, early intensive neurorehabilitation (EIN) for people with PDOC is recommended to achieve the best possible outcomes. ObjectivesTo evaluate the frequency and extent of recovery of consciousness, mortality, complications, pain and discomfort, and medication during a nationwide EIN programme in people with PDOC after acquired brain injury. We hypothesized that level of consciousness would improve in half of people with PDOC. MethodsProspective cohort study. People with PDOC aged 16 years and older admitted to the EIN department centralized in a single rehabilitation centre in the Netherlands (Libra Rehabilitation & Audiology) were included. The EIN delivers a subacute medical level of care and rehabilitation for a maximum duration of 14 weeks. The outcome measures were level of consciousness (CRS-R), mortality, number of complications, medication and pain/discomfort (NCS-R). ResultsOf the 104 people included, 68 % emerged to a minimal conscious state with command-following or higher during EIN and 44 % regained consciousness. Mortality during EIN was 6 %, and 50 % of deaths followed a non-treatment decision or withdrawal of life-sustaining treatment. Almost all participants had at least 1 medical complication, leading to hospital readmission for 30 %. 73 % showed no pain or discomfort. During EIN, cardiovascular medication and analgesics were reduced by 15 %. ConclusionsDuring the EIN programme, a large percentage of people with PDOC regained at least a minimal conscious state or even consciousness. These outcomes and the frequent medical complications in these people suggest that intensive specialized care should be offered to all people with PDOC. The outcomes of this study might help health professionals to better inform the families of people with PDOC about the short-term prognosis of PDOC.

The signaling pathways in obesity-related complications.

Obesity, a rapidly expanding epidemic worldwide, is known to exacerbate many medical conditions, making it a significant factor in multiple diseases and their associated complications. This threatening epidemic is linked to various harmful conditions such as type 2 diabetes mellitus, hypertension, metabolic dysfunction-associated steatotic liver disease, polycystic ovary syndrome, cardiovascular diseases (CVDs), dyslipidemia, and cancer. The rise in urbanization and sedentary lifestyles creates an environment that fosters obesity, leading to both psychosocial and medical complications. To identify individuals at risk and ensure timely treatment, it is crucial to have a better understanding of the pathophysiology of obesity and its comorbidities. This comprehensive review highlights the relationship between obesity and obesity-associated complications, including type 2 diabetes, hypertension, (CVDs), dyslipidemia, polycystic ovary syndrome, metabolic dysfunction-associated steatotic liver disease, gastrointestinal complications, and obstructive sleep apnea. It also explores the potential mechanisms underlying these associations. A thorough analysis of the interplay between obesity and its associated complications is vital in developing effective therapeutic strategies to combat the exponential increase in global obesity rates and mitigate the deadly consequences of this polygenic condition.

Evaluation of the effect of COVID-19 infection in pregnancy and puerperium in a suburban medical college in West Bengal, India

ABSTRACT Background: The pandemic of SARS-CoV-2 was a novel situation, there was no conclusive knowledge, particularly concerning its effect on pregnant women and infants. Eminent obstetric organizations have introduced an array of guidelines to assist clinicians in countering this prior unknown outbreak. The primary objective of this study was to summarize the clinical characteristics, complications, and maternal and neonatal outcomes of COVID-19 during pregnancy and puerperium. Methods: This was a cross-sectional observational study conducted in the Outpatient/Emergency/Inpatient or COVID ward in the Department of Obstetrics and Gynaecology, of a tertiary hospital in Nadia district, West Bengal, India, from 1.7.2020 to 30.6.2021 including 104 pregnant or puerperal mothers with laboratory-confirmed, i.e., RT-PCR or Rapid Antigen Test positive reports after informed consent. The obstetric outcome, modes of delivery, and neonatal status including any complications or SNCU admission within six weeks postpartum were recorded. Results: The majority were in the ≥ 20–24 years age group, primigravida, residents of Nadia with no significant travel or contact history. 73.08% were affected in the third trimester and the comorbidities detected were chiefly anemia (15.38%), hypertensive or chronic liver diseases, and hypothyroidism. 45.19% of the mothers were asymptomatic while the other complaints were fever (18.27%), cough (11.55%), anosmia and/or ageusia (10.58%), sore throat (9.61%), respiratory distress, loose stools, and chest pain. The medical complications were predominantly low SpO2, convulsions, pneumonitis, and two maternal deaths. The obstetric complications were preterm birth (26.9%), pre-eclampsia/eclampsia (17.3%), antepartum (3.9%) and postpartum hemorrhage (4.4%), and sepsis (5.8%). Fourteen mothers had first-trimester termination, 63 had vaginal deliveries, and the rest had cesarean section. Out of 90 neonates, most were in the range of ≥ 2–2.5 kg birth weight and normal 1-min APGAR score. None tested positive for COVID-19 RTPCR and no detectable congenital anomaly or neonatal death was recorded.

Impact of acute ischemic stroke on mortality in gastrointestinal malignancies: A nationwide analysis.

e16372 Background: Acute ischemic stroke, marked by a sudden loss of brain blood supply, carries potential life-threatening consequences. The impact on individuals with pre-existing gastrointestinal (GI) malignancies, coupled with ensuing complex medical complications affecting morbidity and mortality, remains inadequately understood. This study aims to assess the influence of acute ischemic stroke on in-hospital mortality in GI cancer patients in the United States. Methods: This retrospective analysis utilized the 2016-2020 National Inpatient Survey (NIS) database. Adults aged 18 and above with esophageal, gastric, colon, cholangiocarcinoma, hepatocellular carcinoma, and pancreatic cancers were identified using the International Classification of Disease-10 (ICD-10) code. The cohort was stratified into patients with and without acute ischemic stroke. Hospital mortality was analyzed using STATA 18, adjusted for age, gender, race, insurance, Charlson’s index, baseline hospital characteristics, and comorbidities. Multivariate logistic regression analysis was performed, with all P values ≤ 0.05 considered statistically significant. Results: Among 2,133,465 adults with GI malignancies, 28,394 were hospitalized with acute ischemic stroke. Patients with acute ischemic stroke were older (mean age 71.19 vs. 67.01 years; P &lt; 0.001), more likely to be male (55.47%, P = 0.002), Caucasian (67.96%, P &lt; 0.001), from urban teaching hospitals (76.83%, P = 0.011), and had Medicare insurance (70.50%, P &lt; 0.001). Acute ischemic stroke was most associated with pancreatic cancer (39.81%), colon cancer (30.13%), and esophageal cancer (9.86%). Within the cohort of patients with acute ischemic stroke, esophageal cancer patients had the highest mortality rates of 20%. After adjusting for potential confounders, patients with colon cancer, esophageal cancer, gastric cancer, pancreatic cancer, cholangiocarcinoma, and hepatocellular carcinoma had significantly higher odds of in-hospital mortality of 2.91, 2.50, 2.31, 2.22, 1.65, and 1.51, respectively. Conclusions: This study reveals an association between outcomes in hospitalized GI cancer patients and acute ischemic stroke, leading to increased mortality despite adjusting for potential confounders. The impact of anticancer therapies on the vascular system may influence the risk and severity of ischemic events. Further studies are needed to develop tailored prevention, diagnosis, and management strategies to reduce disease complications and the overall healthcare burden of cerebrovascular events.

A Multidisciplinary Approach to Hip Fractures: Evaluating Outcomes on Mortality and Secondary Hip Fractures.

Fracture liaison services (FLS) have been introduced in Japan and several other countries to reduce medical complications and secondary fractures. We aimed to evaluate the effects of the implementation of an FLS approach on patient outcomes during hospitalization at our hospital and over a 2-year follow-up post-injury. This retrospective cohort study included patients ≥ 60 years admitted to our hospital for hip fragility fractures between October 1, 2016, and July 31, 2020. Patient groups were defined as those treated before (control group, n=238) and after (FLS group, n=196) establishment of the FLS protocol at our institution. The two groups were compared in terms of time to surgery, length of hospital stay, and the incidence of complications after admission, including secondary hip fracture and mortality rates. The follow-up period was 24 months. FLS focuses on early surgery within 48 h of injury and assessing osteoporosis treatment before injury to guide post-discharge anti-osteoporosis medication. FLS reduced the length of hospital stay (p<0.001) and the prevalence of complications after admission (p<0.001), particularly cardiovascular disease, and it increased adherence to anti-osteoporosis medication. These FLS effects resulted in lower secondary hip fracture and mortality rates at 12 and 24 months post-injury. FLS for fragility hip fractures can improve patient outcomes during hospitalization and over a 2-year follow-up period.

Short-Term (90 Days) Clinical Outcomes Following the Day of Surgery Conversion of Inpatient to Same-Day Hip and Knee Arthroplasty

BackgroundThe incidence of total joint arthroplasty is increasing, with added emphasis on shifting care toward outpatient surgery. This has demonstrated improvements in costs and care; however, safety must be prioritized. Published assessment tools highlight candidates for outpatient surgery; however, they often do not define patients who have a worse prognosis. Limited healthcare resources occasionally force patients to convert to outpatient surgery or risk cancellation, creating a dilemma for both patients and surgeons. We evaluated the short-term (90-day) outcomes of patients converted from planned inpatient admission to same-day discharge on day of surgery outpatients and sought to identify any groups at risk, who may not be appropriate for this conversion. MethodsWe identified all patients undergoing planned inpatient total hip or knee arthroplasty at a tertiary academic medical center over a 2-year period. We included patients discharged the day of surgery for analysis, excluding revision procedures and those performed for fracture care. A manual chart review identified demographic factors and primary outcome measures; including reoperation, readmission, and emergency room visits within a 90-day postoperative period. ResultsWe identified a total of 80 patients who converted from inpatient to outpatient surgery over a 2-year interval. Over the first 90 days postoperatively 4 (5%) patients were readmitted: 2 (2.5%) for medical complications and 2 (2.5%) for reoperation. There were 2 (2.5%) reoperations; one (1.25%) for manipulation under anesthesia, and one (1.25%) for periprosthetic joint infection. There were 5 (6.3%) wound complications; however, only one (1.25%) required surgical intervention. A total of 5 (6.3%) patients returned to an emergency department, leading to a single (1.25%) hospital readmission. ConclusionsHospital and healthcare resources are occasionally limited to the extent that patients must convert to outpatient surgery or risk cancellation. At our institution, the same-day conversion of planned inpatient hip and knee arthroplasty patients to outpatient surgery was safe and did not increase short-term clinical outcomes or complications.
