RESUMO

INTRODUCTION: This study aimed to compare the early postoperative outcomes of right anterior thoracotomy minimally invasive aortic valve replacement (RAT-MIAVR) surgery with those of median full sternotomy aortic valve replacement (MFS-AVR) approach with the goal of identifying potential benefits or drawbacks of each technique. METHODS: This retrospective, observational, cohort study included 476 patients who underwent RAT-MIAVR or MFS-AVR in our hospital from January 2015 to January 2023. Of these, 107 patients (22.5%) underwent RAT-MIAVR, and 369 patients (77.5%) underwent MFS-AVR. Propensity score matching was used to minimize selection bias, resulting in 95 patients per group for analysis. RESULTS: After propensity matching, two groups were comparable in preoperative characteristics. RAT-MIAVR group showed longer cardiopulmonary bypass time (130.24 ± 31.15 vs. 117.75 ± 36.29 minutes, P=0.012), aortic cross-clamping time (76.44 ± 18.00 vs. 68.49 ± 19.64 minutes, P=0.004), and longer operative time than MFS-AVR group (358.47 ± 67.11 minutes vs. 322.42 ± 63.84 minutes, P=0.000). RAT-MIAVR was associated with decreased hospitalization time after surgery, lower postoperative blood loss and drainage fluid, a reduced incidence of mediastinitis, increased left ventricular ejection fraction, and lower pacemaker use compared to MFS-AVR. However, there was no significant difference in the incidence of major complications and in-hospital mortality between the two groups. CONCLUSION: RAT-MIAVR is a feasible and safe alternative procedure to MFS-AVR, with comparable in-hospital mortality and early follow-up. This minimally invasive approach may be a suitable option for patients requiring isolated aortic valve replacement.

RESUMO

Background: Splenic angioembolization (SAE) has increased in utilization for blunt splenic injuries. We hypothesized lower SAE usage would not correlate with higher rates of additional intervention or mortality when choosing initial non-operative management (NOM) or surgery. Study design: Trauma registries from two level I trauma centers from 2010 to 2020 were used to identify patients aged >18 years with grade III-V blunt splenic injuries. Results were compared with the National Trauma Data Bank (NTDB) for 2018 for level I and II centers. Additional intervention or failure was defined as any subsequent SAE or surgery. Mortality was defined as death during admission. Results: There were 266 vs 5943 patients who met inclusion/exclusion criteria at Stanford/Santa Clara Valley Medical Center (SCVMC) versus the NTDB. Initial intervention differed significantly between cohorts with the use of SAE (6% vs 17%, p=0.000). Failure differed significantly between cohorts (1.5% vs 6.5%, p=0.005). On multivariate analysis, failure in NOM was significantly associated with NTDB cohort status, age 65+ years, more than one comorbidity, mechanism of injury, grade V spleen injury, and Injury Severity Score (ISS) 25+. On multivariate analysis, failure in SAE was significantly associated with Shock Index >0.9 and 10+ units blood in 24 hours. On multivariate analysis, a higher risk of mortality was significantly associated with NTDB cohort status, age 65+ years, no private insurance, more than one comorbidity, mechanism of injury, ISS 25+, 10+ units blood in 24 hours, NOM, more than one hospital complications, anticoagulant use, other Abbreviated Injury Scale ≥3 abdominal injuries. Conclusions: Compared with national data, our cohort had less SAE, lower rates of additional intervention, and had lower risk-adjusted mortality. Shock Index >0.9, grade V splenic injuries, and increased transfusion requirements in the first 24 hours may signal a need for surgical intervention rather than SAE or NOM and may reduce mortality in appropriately selected patients. Level of evidence: Level II/III.

RESUMO

BACKGROUND: Molar root canal treatment (RCT) is challenging and requires training and specific skills. Rotary instrumentation (RI) reduces the time needed for instrumentation but may increase the risk of certain procedural errors. The aims of this study were to evaluate the quality of molar RCTs provided by undergraduate students, to compare the prevalence of procedural errors following manual and RI, and to assess the students' self-perceived confidence to perform molar RCT without supervision and their preference for either manual or RI. METHODS: Molar RCTs performed by the final year students were evaluated radiographically according to predefined criteria (Appendix 1). The procedural errors, treatment details, and the students' self-perceived confidence to perform molar RCT and their preference for either manual or RI were recorded. Descriptive statistics were performed, and the Chi-squared test was used to detect any statistically significant differences. RESULTS: 60.4% of RCTs were insufficient. RI resulted in more sufficient treatments compared with MI (49% vs. 30.3% respectively. X2: 7.39, p = 0.007), required fewer visits to complete (2.9 vs. 4.6 respectively. X2: 67.23, p < 0.001) and was the preferred technique by 93.1% of students. The most common procedural errors were underextension of the root canal obturation (48.4%), insufficient obturation (45.5%), and improper coronal seal (35.2%) without a significant difference between the two techniques. 26.4% of the participating students reported that they did not feel confident to perform molar RCT without supervision. CONCLUSION: The quality of molar RCT provided by UG students was generally insufficient. RI partially improved the technical quality of RCT compared with MI. UG students need further endodontic training and experience before they can safely and confidently practise molar RCT.

RESUMO

Introduction and importance: Fibroepithelial vaginal polyps (FEPV) are rare mucosal polypoid lesions primarily found in adult women. However, FEPV in paediatric patients, especially beyond the neonatal period, is exceedingly uncommon. Documenting cases improves diagnosis and management. FEPV can mimic malignancy, posing challenges for interpretation. Early detection, treatment, and follow-up are crucial for optimal outcomes. Case presentation: The authors present the case of a 2-year-old girl with a recurrent FEPV. The patient had a painless, reddish, smooth, soft, rubbery polypoid vaginal mass measuring 2.3 × 1.5 cm. Physical examination revealed no concurrent systemic issues. Surgical excision of the polyps confirmed them as fibroepithelial polyps. Despite previous excisions, the polyps recurred within a month. The patient's postoperative recovery was uneventful, and subsequent follow-up showed no recurrence. Clinical discussion: FEPV presents as mucosal polypoid lesions with a connective tissue core covered by benign squamous epithelium. It is rare before menarche and after menopause. Although the pathophysiology remains unclear, hormonal factors and local injuries may contribute. FEPV is usually asymptomatic but may cause pressure, obstruction, bleeding, or discharge. Differential diagnosis includes vaginal connective tissue malignancies. The diagnosis was confirmed by surgical excision and histopathology. Complete excision is crucial for preventing recurrence. Conclusion: This case report highlights recurrent FEPV in a 2-year-old girl. Despite previous excisions, polyps recurred, emphasizing the need for complete excision. Documenting cases will enhance our understanding. Further research is needed to elucidate the pathogenesis of paediatric FEPV. Early detection, treatment, and follow-up are essential for optimal management.

RESUMO

STUDY DESIGN: Systematic review. OBJECTIVES: Primary Spinal Intradural Tumours (PSITs) are rare pathologies that can significantly impact quality of life. This study aimed to review patient reported outcomes (PROs) in PSITs. METHODS: A systematic search of Pubmed and Embase was performed to identify studies measuring PROs in adults with PSITs. PRO results were categorised as relating to Global, Physical, Social, or Mental health. Outcomes were summarised descriptively. RESULTS: Following review of 2382 records, 11 studies were eligible for inclusion (737 patients). All studies assessed surgically treated patients. Schwannoma was the commonest pathology (n = 190). 7 studies measured PROs before and after surgery, the remainder assessed only post-operatively. For eight studies, PROs were obtained within 12 months of treatment. 21 PRO measurement tools were used across included studies, of which Euro-Qol-5D (n = 8) and the pain visual/numerical analogue scale (n = 5) were utilised most frequently. Although overall QoL is lower than healthy controls in PSITs, improvements following surgery were found in Extramedullary tumours (EMT) in overall physical, social, and mental health. Similar improvements were not significant across studies of Intramedullary tumours (IMT). Overall QoL and symptom burden was higher in IMT patients than in brain tumour patients. No studies evaluated the effect of chemotherapy or radiotherapy. CONCLUSION: Patients with PSITs suffer impaired PROs before and after surgery. This is particularly true for IMTs. PRO reporting in PSITs is hindered by a heterogeneity of reporting and varied measurement tools. This calls for the establishment of a standard set of PROs as well as the use of registries.

RESUMO

Chickpea is a highly nutritious protein-rich source and one of the major crops to alleviate global malnutrition, but poor seed quality affects its productivity. Seed quality is essential for better crop establishment and higher yields, particularly in the uncertain climate change. The present study investigated the impact of botanical priming versus hydropriming and bavistin seed treatment on chickpea seeds. A detailed physiological (germination percentage, root and shoot length, vigour index) and biochemical (amylase, protease, dehydrogenase, phytase, and lipid peroxidation) analysis was carried out in order to assess the effect of priming treatments. Turmeric-primed seeds showed better germination rate (94.5%), seedling length, enzyme activity, and lower malondialdehyde (MDA) content. Sodium dodecyl-sulfate polyacrylamide gel electrophoresis (SDS-PAGE) analysis revealed the expression of minor polypeptides of albumin and globulin in the primed seeds. Moreover, field experiments indicated increased crop growth, vigour, days to 50% flowering, yield and its attributing traits in turmeric-primed seeds. Botanical priming can increase chickpea yield by up to 16% over the control group. This low-cost and eco-friendly technique enhances seed and crop performance, making it a powerful tool for augmenting chickpea growth. Therefore, chickpea growers must adopt botanical priming techniques to enhance the quality of seed and crop performance. Moreover, this approach is environmentally sustainable and can help conserve natural resources in the long term. Therefore, this new approach must be widely adopted across the agricultural industry to ensure sustainable and profitable farming practices.

RESUMO

BACKGROUND: The use of naturally occurring bioactive materials is getting great attention owing to their safety and environmental properties. Oily compounds, known as oleoresins, are expected to provide an important source for the natural products industry aiming to develop novel treatments for skin conditions. In this work, Capsicum annuum oleoresin nanoemulgel formulations have been prepared and investigated for their antibacterial and anticancer properties. METHODOLOGY: Several C. annuum oleoresin nanoemulgel formulations were prepared by incorporating a Carbopol 940 gel in a self-nanoemulsifying nanoemulsion consisting of C. annuum, tween 80, and span 80. The systems were characterized for particle size, polydispersity index (PDI), zeta potential, and rheology. The in vitro antimicrobial and cytotoxic activities of the optimum formulation were evaluated. RESULTS: The selected formulation is composed of 40% tween, 10% span 80, and 40% C. annuum oleoresin. This formulation produced a stable nanoemulsion with a narrow PDI value of 0.179 ± 0.08 and a droplet size of 104.0 ± 2.6 nm. Results of the in vitro antimicrobial studies indicated high potency of the systems against methicillin-resistant Staphylococcus aureus (MRSA) (zone of inhibition of 29 ± 1.9 mm), E. coli (33 ± 0.9 mm), K. pneumonia (30 ± 1.4 mm), and C. albicans (21 ± 1.5 mm), as compared to the reference antibiotic, ampicillin (18 ± 1.4 mm against K. pneumonia), and antifungal agent, fluconazole (12 ± 0.1 mm against C. albicans). Furthermore, cytotoxicity results, expressed as IC50 values, revealed that the oleoresin and its nanoemulgel had the best effects against the HepG2 cell line (IC50 value of 79.43 µg/mL for the nanoemulgel) and MCF7 (IC50 value of 57.54 µg/mL), and the most potent effect was found against 3T3 (IC50 value of 45.7 µg/m- L). On the other side, the system did not substantially exhibit activity against By-61 and Hela. CONCLUSION: C. annuum oleoresin and its nanoemulgel can be considered valuable sources for the discovery of new antibacterial, antifungal, and anticancer compounds in the pharmaceutical industry, especially due to their potent activity against various cancer cell lines as well as bacterial and fungal strains.

RESUMO

Thyroidectomy is common and is performed for malignancy, goiters with pressure symptoms, and certain types of Grave's disease. Weight and body mass index (BMI) following thyroidectomy were discussed controversially. This meta-analysis aimed to assess weight and BMI following thyroidectomy. A systematic literature search was conducted in PubMed, Medline, and Google Scholar with interest in articles that assessed body weight and BMI following total or subtotal thyroidectomy. The search engine was limited to the period from inception up to January 2024. Keywords "total thyroidectomy", "subtotal thyroidectomy", "Graves' disease", "multinodular goiter", "differentiated thyroid carcinoma", and "toxic nodules" were used. Out of the 634 articles retrieved, 89 full texts were screened, and only six studies (five retrospective and one prospective cohort) fulfilled the inclusion and exclusion criteria. No differences were evident regarding weight and BMI before and after thyroidectomy (odds ratio: -0.63, 95%CI: -1.50 to -0.24, P-value for the overall effect: 0.15; and odds ratio: -0.12, 95% CI: -0.41 to -0.16, P-value for the overall effect: 0.40 respectively). No heterogeneity was observed (I2 for heterogeneity: 0.0%). No association between thyroidectomy (when performed for differentiated thyroid carcinoma and hyperthyroidism), weight, and BMI was found. Further studies assessing thyroid-stimulating hormone (TSH) levels, radioactive iodine therapy, and thyroxine dose are needed.

RESUMO

BACKGROUND: Roux-en-Y gastric bypass (RYGB) effectively treats severe obesity, but some patients may require revisional surgery like limb lengthening (LL) for postoperative weight gain. OBJECTIVES: This study aims to compare 30-day serious complications and mortality rates between LL and primary RYGB, given limited safety data on LL. METHODS: Patients who underwent LL and RYGB were identified from the 2020 and 2021 MBSAQIP databases, the only years in which LL data were available. Baseline characteristics and 30-day rates of serious complications and mortality were analyzed. RESULTS: A total of 86,990 patients underwent RYGB and 455 underwent LL. Patients undergoing RYGB were younger (44.4 versus 49.8 yr, P < .001), had a higher body mass index (BMI) (45.5 versus 41.8 kg/m2, P < .001) and higher rates of comorbidities including diabetes (30.0 versus 13.6%, P < .001). RYGB and LL had similar operative duration (125.3 versus 123.2 min, P = .5). There were no statistical differences between cohorts for length of stay (LOS) (1.6 RYGB versus 1.6 LL d, P = .6). After LL, there were higher 30-day rates of reoperation (3.3 versus 1.9%, P = .03) and deep surgical site infections (1.3 versus .5%, P = .03) compared to RYGB. There were no differences in overall serious complications (5.1 LL versus 5.0% RYGB, P = 1.0) and mortality (.2 LL versus .1% RYGB, P = .5). Multivariable logistic regression adjustment found that previous venous thromboembolism was associated with serious complications after LL. CONCLUSIONS: When compared to primary RYGB, LL has a favorable safety profile with similar 30-day rates of serious complications and mortality.

RESUMO

Cavernous hemangioma of the bladder is a benign and very rare vascular tumor. It can be isolated or part of a syndrome. Neither clinical symptoms nor imaging modalities lead to a definitive diagnosis as there are no specific findings on imaging studies or specific symptoms. Painless gross hematuria is the most common chief complaint and presentation and should never be underestimated. Here, we report a case of a large hemangioma of the urinary bladder in a young man who presented with recurrent recent episodes of painless gross hematuria and, surprisingly, with a previous episode of painless hematuria 15 years ago, which was treated successfully with partial cystectomy. We discuss the clinical features, evaluation, diagnosis, biopsy, management, the challenges encountered in treatment, and assert the value of tissue diagnosis and follow-up pattern and period. Due to the rarity of the tumor and lack of trials and evidence-based guidelines for management, treatment modalities vary and the risk for recurrence is questionable and not known.

RESUMO

The free living Acanthamoeba spp. are ubiquitous amoebae associated with potentially blinding disease known as Acanthamoeba keratitis (AK) and a fatal central nervous system infection granulomatous amoebic encephalitis (GAE). With the inherent ability of cellular differentiation, it can phenotypically transform to a dormant cyst form from an active trophozoite form. Acanthamoeba cysts are highly resistant to therapeutic agents as well as contact lens cleaning solutions. One way to tackle drug resistance against Acanthamoeba is by inhibiting the formation of cysts from trophozoites. The biochemical analysis showed that the major component of Acanthamoeba cyst wall is composed of carbohydrate moieties such as galactose and glucose. The disaccharide of galactose and glucose is lactose. In this study, we analyzed the potential of lactase enzyme to target carbohydrate moieties of cyst walls. Amoebicidal assessment showed that lactase was ineffective against trophozoite of A. castellanii but enhanced amoebicidal effects of chlorhexidine. The lactase enzyme did not show any toxicity against normal human keratinocyte cells (HaCaT) at the tested range. Hence, lactase can be used for further assessment for development of potential therapeutic agents in the management of Acanthamoeba infection as well as formulation of effective contact lens disinfectants.

RESUMO

BACKGROUNDThe tumor immune microenvironment can provide prognostic and therapeutic information. We aimed to develop noninvasive imaging biomarkers from computed tomography (CT) for comprehensive evaluation of immune context and investigate their associations with prognosis and immunotherapy response in gastric cancer (GC).METHODSThis study involved 2,600 patients with GC from 9 independent cohorts. We developed and validated 2 CT imaging biomarkers (lymphoid radiomics score [LRS] and myeloid radiomics score [MRS]) for evaluating the IHC-derived lymphoid and myeloid immune context respectively, and integrated them into a combined imaging biomarker [LRS/MRS: low(-) or high(+)] with 4 radiomics immune subtypes: 1 (-/-), 2 (+/-), 3 (-/+), and 4 (+/+). We further evaluated the imaging biomarkers' predictive values on prognosis and immunotherapy response.RESULTSThe developed imaging biomarkers (LRS and MRS) had a high accuracy in predicting lymphoid (AUC range: 0.765-0.773) and myeloid (AUC range: 0.736-0.750) immune context. Further, similar to the IHC-derived immune context, 2 imaging biomarkers (HR range: 0.240-0.761 for LRS; 1.301-4.012 for MRS) and the combined biomarker were independent predictors for disease-free and overall survival in the training and all validation cohorts (all P < 0.05). Additionally, patients with high LRS or low MRS may benefit more from immunotherapy (P < 0.001). Further, a highly heterogeneous outcome on objective response ​rate was observed in 4 imaging subtypes: 1 (-/-) with 27.3%, 2 (+/-) with 53.3%, 3 (-/+) with 10.2%, and 4 (+/+) with 30.0% (P < 0.0001).CONCLUSIONThe noninvasive imaging biomarkers could accurately evaluate the immune context and provide information regarding prognosis and immunotherapy for GC.

RESUMO

STUDY DESIGN: prospective multicenter study. OBJECTIVES: Active apex correction (APC) is posterior tethering technique for correction of early onset scoliosis (EOS) via reverse modulation at the apex. Active apex correction has been increasingly used worldwide. This study aimed to assess short-term outcomes of multicenter study with ≥2 years of APC on spine length, curve correction, complications, unplanned surgeries, and proposed low crankshaft phenomena incidence. METHODS: Prospective multicenter study including 24 EOS patients treated by APC; involves inserting and compressing pedicle screws on convex side of apex proximal and distal to most wedged vertebra allowing apex modulation according to Hueter-Volkmann law. Excluded patients with <2 years follow-up whom APC was not primary surgery. RESULTS: Mean age 85.97 ± 32.43 months, 71% congenital scoliosis, mean follow-up 35.54 ± 12.36 months. At final follow-up, statistically significant improvement in Cobbs angle (∆ = 23.96%, P < .0001), spinal length T1-T12 (∆ = 12.83%, P < .0001), T1-L5 (∆ = 13.41%, P < .0001) but not in apical vertebral translation (AVT) albeit clinical improvement (∆ = 7.9%, P = .36) compared to preoperative measurements. Comparing immediate postoperative measurements to >2 years follow-up, statistically significant improvement in spinal length T1-T12 (∆ = 6.03%, P = .0002) and T1-L5 (∆ = 6.26%, P < .0001) but not in Cobbs angle (∆ = 4.93%, P = .3) or AVT (∆ = 14.77%, P = .25). 9 complications requiring 3 unplanned surgeries recorded in all patients including 2 broken rods, 2 adding-on and 4 screw dislodgement. CONCLUSION: Active apex correction is a novel technique that has been incorporated in several countries as treatment modality for EOS. Short-term outcomes are promising in terms of clinical improvement, complication rates and decreased need for multiple operations or unplanned surgeries.

RESUMO

PURPOSE: To determine whether a 12-week supervised dose-graded aerobic exercise (D-GAE) training, when implemented in conjunction with traditional rehabilitation, could help pediatric survivors of acute lymphoblastic leukemia (ALL) enhance their cardiopulmonary capacity and improve their physical performance. METHODS: Fifty-eight pediatric survivors of ALL (age 13.78 ± 2.47 years; boys 60.34%) were assigned at random to either undergo the D-GAE in addition to the traditional physical rehabilitation (D-GAE group; n = 29) or the traditional physical rehabilitation solely (control group; n = 29). The cardiopulmonary fitness (peak oxygen uptake (VO2peak), ventilatory equivalent (VEq/VO2), minute ventilation (VE, L/min), oxygen pulse (O2P), maximum heart rate (HRmax), 1-min heart rate recovery (HRR1), and respiratory exchange ratio (RER)) and physical performance (6-min walk test (6-MWT), timed up and down stairs (TUDS), and 4 × 10-m shuttle run test (4 × 10mSRT)) were assessed on the pre- and post-intervention occasions. RESULTS: The mixed-model ANOVA revealed a meaningful increase of VO2peak (P = .002), VE (P = .026), O2P (P = .0009), HRmax (P = .004), and HRR1 (P = .011), and reduction of VEq/VO2 (P = .003) and RER (P = .003) in the D-GAE group compared with the control group. Besides, the analysis detected a favorable increase in the physical performance for the D-GAE group (6-MWT (P = .007), TUDS (P < .001), 4 × 10mSRT (P = .009)). CONCLUSION: A 12-week D-GAE program in conjunction with traditional rehabilitation holds promise in enhancing cardiopulmonary fitness and improving the physical performance of pediatric survivors of ALL. Clinicians and physical rehabilitation professionals can, therefore, integrate the D-GAE into the traditional rehabilitation protocols for such a patient population to optimize their cardiopulmonary fitness and physical function, while also facilitating a gradual transition to practice and adaption. IMPLICATIONS FOR CANCER SURVIVORS: The favorable outcomes of this study bolster the inclusion of D-GAE as a crucial element in the care and rehabilitation of pediatric survivors of ALL. By embracing these findings, healthcare professionals and oncologists can contribute to mitigating the long-term cardiopulmonary and physical complications associated with cancer treatments and fostering a state of enhanced well-being and increased physical activity among survivors.

RESUMO

Toxoplasma gondii causes a global parasitic disease. Therapeutic options for eradicating toxoplasmosis are limited. In this study, ZnO and Mg-doped ZnO NPs were prepared, and their structural and morphological chrematistics were investigated. The XRD pattern revealed that Mg-doped ZnO NPs have weak crystallinity and a small crystallite size. FTIR and XPS analyses confirmed the integration of Mg ions into the ZnO framework, producing the high-purity Mg-doped ZnO nanocomposite. TEM micrographs determined the particle size of un-doped ZnO in the range of 29 nm, reduced to 23 nm with Mg2+ replacements. ZnO and Mg-doped ZnO NPs significantly decreased the number of brain cysts (p < 0.05) by 29.30% and 35.08%, respectively, compared to the infected untreated group. The administration of ZnO and Mg-doped ZnO NPs revealed a marked histopathological improvement in the brain, liver, and spleen. Furthermore, ZnO and Mg-doped ZnO NPs reduced P53 expression in the cerebral tissue while inducing CD31 expression, which indicated a protective effect against the infection-induced apoptosis and the restoration of balance between free radicals and antioxidant defense activity. In conclusion, the study proved these nanoparticles have antiparasitic, antiapoptotic, and angiogenetic effects. Being nontoxic compounds, these nanoparticles could be promising adjuvants in treating chronic toxoplasmosis.

RESUMO

Peripheral ameloblastoma (PA) is a rare variant of ameloblastoma that presents as a slow-growing, painless mass in the gingival tissues or alveolar mucosa. It shares histologic features with conventional ameloblastoma but is less invasive and aggressive. This case report describes a 51-year-old female with a PA that simultaneously or subsequently developed underlying squamous cell papilloma after mandibular third molar extraction. Clinical examination revealed a pedunculated gingival lesion mimicking squamous cell papilloma. Histopathologic examination confirmed PA underlying squamous cell papilloma after an excisional biopsy. Imaging revealed mild bone resorption, leading to a further soft tissue excision and minimal osteoectomy to rule out intraosseous involvement. The patient remained asymptomatic without signs of recurrence in the 1-year follow-up. PA diagnosis can be challenging due to its clinical resemblance to other gingival lesions and histopathologic features. Treatment typically involves surgical excision, with long-term follow-up recommended due to possible recurrence and malignant transformation.

RESUMO

OBJECTIVES: To assess the body of literature examining episode-based bundled payment models effect on health care spending, utilization, and quality of care for surgical conditions. BACKGROUND SUMMARY: Episode-based bundled payments were developed as a strategy to lower healthcare spending and improve coordination across phases of healthcare. Surgical conditions may be well-suited targets for bundled payments because they often have defined periods of care and widely variable healthcare spending. In bundled payment models, hospitals receive financial incentives to reduce spending on care provided to patients during a predefined clinical episode. Despite the recent proliferation of bundles for surgical conditions, a collective understanding of their effect is not yet clear. METHODS: A scoping review was conducted, and four databases were queried from inception through September 27, 2021, with search strings for bundled payments and surgery. All studies were screened independently by two authors for inclusion. RESULTS: Our search strategy yielded a total of 879 unique articles of which 222 underwent a full-text review and 28 met final inclusion criteria. Of these studies, most (23 of 28) evaluated the impact of voluntary bundled payments in orthopedic surgery and found that bundled payments are associated with reduced spending on total care episodes, attributed primarily to decreases in post-acute care spending. Despite reduced spending, clinical outcomes (e.g., readmissions, complications, and mortality) were not worsened by participation. Evidence supporting the effects of bundled payments on cost and clinical outcomes in other non-orthopedic surgical conditions remains limited. CONCLUSIONS: Present evaluations of bundled payments primarily focus on orthopedic conditions and demonstrate cost savings without compromising clinical outcomes. Evidence for the effect of bundles on other surgical conditions and implications for quality and access to care remain limited.

RESUMO

Abstract Cancer is a fatal malignancy and its increasing worldwide prevalence demands the discovery of more sensitive and reliable molecular biomarkers. To investigate the GINS1 expression level and its prognostic value in distinct human cancers using a series of multi-layered in silico approach may help to establish it as a potential shared diagnostic and prognostic biomarker of different cancer subtypes. The GINS1 mRNA, protein expression, and promoter methylation were analyzed using UALCAN and Human Protein Atlas (HPA), while mRNA expression was further validated via GENT2. The potential prognostic values of GINS1 were evaluated through KM plotter. Then, cBioPortal was utilized to examine the GINS1-related genetic mutations and copy number variations (CNVs), while pathway enrichment analysis was performed using DAVID. Moreover, a correlational analysis between GINS1 expression and CD8+ T immune cells and a the construction of gene-drug interaction network was performed using TIMER, CDT, and Cytoscape. The GINS1 was found down-regulated in a single subtypes of human cancer while commonly up-regulated in 23 different other subtypes. The up-regulation of GINS1 was significantly correlated with the poor overall survival (OS) of Liver Hepatocellular Carcinoma (LIHC), Lung Adenocarcinoma (LUAD), and Kidney renal clear cell carcinoma (KIRC). The GINS1 was also found up-regulated in LIHC, LUAD, and KIRC patients of different clinicopathological features. Pathways enrichment analysis revealed the involvement of GINS1 in two diverse pathways, while few interesting correlations were also documented between GINS1 expression and its promoter methylation level, CD8+ T immune cells level, and CNVs. Moreover, we also predicted few drugs that could be used in the treatment of LIHC, LUAD, and KIRC by regulating the GINS1 expression. The expression profiling of GINS1 in the current study has suggested it a novel shared diagnostic and prognostic biomarker of LIHC, LUAD, and KIRC.


Resumo O câncer é uma doença maligna fatal e sua crescente prevalência mundial exige a descoberta de biomarcadores moleculares mais sensíveis e confiáveis. Investigar o nível de expressão de GINS1 e seu valor prognóstico em cânceres humanos distintos, usando uma série de abordagens in silico em várias camadas, pode ajudar a estabelecê-lo como um potencial biomarcador de diagnóstico e prognóstico compartilhado de diferentes subtipos de câncer. O mRNA de GINS1, a expressão da proteína e a metilação do promotor foram analisados usando UALCAN e Human Protein Atlas (HPA), enquanto a expressão de mRNA foi posteriormente validada via GENT2. Os valores prognósticos potenciais de GINS1 foram avaliados por meio do plotter KM. Em seguida, o cBioPortal foi utilizado para examinar as mutações genéticas relacionadas ao GINS1 e as variações do número de cópias (CNVs), enquanto a análise de enriquecimento da via foi realizada usando DAVID. Além disso, uma análise correlacional entre a expressão de GINS1 e células imunes T CD8 + e a construção de uma rede de interação gene-droga foi realizada usando TIMER, CDT e Cytoscape. O GINS1 foi encontrado regulado negativamente em um único subtipo de câncer humano, enquanto comumente regulado positivamente em 23 outros subtipos diferentes. A regulação positiva de GINS1 foi significativamente correlacionada com a sobrevida global pobre (OS) de Carcinoma Hepatocelular de Fígado (LIHC), Adenocarcinoma de Pulmão (LUAD) e Carcinoma de Células Claras Renais de Rim (KIRC). O GINS1 também foi encontrado regulado positivamente em pacientes LIHC, LUAD e KIRC de diferentes características clínico-patológicas. A análise de enriquecimento de vias revelou o envolvimento de GINS1 em duas vias diversas, enquanto poucas correlações interessantes também foram documentadas entre a expressão de GINS1 e seu nível de metilação do promotor, nível de células imunes T CD8 + e CNVs. Além disso, também previmos poucos medicamentos que poderiam ser usados no tratamento de LIHC, LUAD e KIRC, regulando a expressão de GINS1. O perfil de expressão de GINS1 no estudo atual sugeriu que é um novo biomarcador de diagnóstico e prognóstico compartilhado de LIHC, LUAD e KIRC.
