An Unusual Coexistence: Right-Sided Colon Cancer and Intestinal Malrotation in an Adult.

Intestinal malrotation (IM), a rare congenital anomaly disrupting typical embryonic rotation around the superior mesenteric artery, is exceptionally uncommon in adults, with its link to colon cancer being even rarer. This article presents a case of colonic cancer in conjunction with IM in a 63-year-old male. Image studies and intraoperative findings show signs of IM. Open resection was performed due to concerns about vascular anomalies and abnormal lymphatic drainage. The case underscores the rarity of colon cancer in a malrotated gut, highlighting the necessity of preoperative identification for precise surgical planning and emphasizing the importance of careful dissection to prevent inadvertent vascular injury.

Routine Use of Neck Drains Following Thyroid Operations to Prevent Complications Is No Longer Advisable.

BACKGROUND: The use of cervical drains to prevent cervical hematoma or seroma after thyroidectomy remains a controversial issue. OBJECTIVE: Identify clinical and surgical risk factors for hematoma or seroma and evaluate the usefulness of routine use of drains following thyroid surgery. MATERIAL AND METHODS: The authors conducted a retrospective multicentric study related to consecutive patients submitted to thyroid surgery in seven Portuguese hospitals between January 2018 and December 2020 (n=945). The data collected included the following parameters: age and gender of the patients, anticoagulation or anti-aggregating therapy, histological diagnoses, type of surgery, the presence or absence of postoperative drains, thyroid weight, length of hospital stay, postoperative complications, and reinterventions. In this study, surgical complications evaluated were limited to the presence of hematoma or seroma. A total of 945 patients who underwent thyroid surgery were included in the study. Twenty-seven patients (2.9%, n=27) experienced complications classified as hematomas or seromas. In the series, significant differences were observed between the two groups according to hypocoagulation or anti-aggregation status (OR=3.62; 95% CI 1.14-11.4) (p=0.001) and the nature of histological diagnosis (toxic vs. non-toxic benign disease) (OR=6.59; 95% CI 1.83-23.7). Hypocoagulation or anti-aggregation status were independently associated with a higher risk of complications. The presence of drains was associated with longer hospitalization periods (p<0.001) and not a decreased need for reintervention. CONCLUSION: Cervical hematoma or seroma are rare complications associated with both hypocoagulation and anti-aggregation therapy and with the presence of benign toxic pathology. The use of drains does not decrease the need for reintervention and is even associated with a longer length of hospital stay; therefore, their routine use should not be advised.

Developmental progression continues during embryonic diapause in the roe deer.

Embryonic diapause in mammals is a temporary developmental delay occurring at the blastocyst stage. In contrast to other diapausing species displaying a full arrest, the blastocyst of the European roe deer (Capreolus capreolus) proliferates continuously and displays considerable morphological changes in the inner cell mass. We hypothesised that developmental progression also continues during this period. Here we evaluate the mRNA abundance of developmental marker genes in embryos during diapause and elongation. Our results show that morphological rearrangements of the epiblast during diapause correlate with gene expression patterns and changes in cell polarity. Immunohistochemical staining further supports these findings. Primitive endoderm formation occurs during diapause in embryos composed of around 3,000 cells. Gastrulation coincides with elongation and thus takes place after embryo reactivation. The slow developmental progression makes the roe deer an interesting model for unravelling the link between proliferation and differentiation and requirements for embryo survival.

Apple Core Unveiled: Malignant Colonic Obstruction Revealing an Unknown Rectosigmoid Neoplasm With Foreign Body Impaction.

This case report highlights a rare clinical scenario of a 46-year-old male presenting with constipation and fecaloid vomiting due to an impacted chicken bone within an unidentified rectosigmoid neoplasm, leading to acute malignant colonic obstruction. Emergent exploratory laparotomy revealed an impacted chicken bone lodged in a previously unknown rectosigmoid tumor. An anatomopathological examination revealed a mucinous adenocarcinoma with clear margins and one pericolic metastatic lymph node. The postoperative period was uneventful, and the patient was proposed for adjuvant chemotherapy. The abrupt onset of symptoms allowed for an early diagnosis, emphasizing the unexpected association between foreign body impaction and incidental malignant obstruction. This case underscores the complexity of managing foreign body ingestion in the gastrointestinal tract and emphasizes the crucial role of diagnostic imaging in surgical planning. Furthermore, it draws attention to the potential occurrence of colorectal cancer in younger individuals, emphasizing the necessity for clinical vigilance and screening strategies beyond conventional age recommendations.

Efficacy and safety of novel left ventricular pacing leads: 1-year analysis of the NAVIGATOR trial.

OBJECTIVES: Assess safety and performance of novel quadripolar preshaped left ventricular (LV) leads: NAVIGO 4LV 2D ('S shaped') and NAVIGO 4LV ARC ('U shaped'). METHODS: Patients indicated for cardiac resynchronisation therapy were enrolled in a multicentre, prospective, controlled study (NAVIGATOR, NCT03279484). Patients were implanted with either a NAVIGO 4LV 2D or ARC lead, and assessed at 10 weeks, 6, 12 and 24 months post-implant. Co-primary safety and performance endpoints were assessed at 10 weeks. Safety endpoint was the patients' rate free from lead-related complications. Performance endpoint was the rate of patients with successful lead performance, defined as LV pacing threshold ≤2.5 V at 0.5 ms on at least one pacing vector, and the absence of phrenic nerve stimulation at the final programmed configuration. Lead-related complications and electrical parameters were monitored throughout study. RESULTS: A NAVIGO 4LV lead was successfully implanted in 211 out of 217 patients (97.2%). The safety endpoint was met, with 100% and 96.1% of patients free from complications for NAVIGO 4LV 2D and ARC, respectively. The performance endpoint was met with 98.1% and 98.9% of patients with a successful lead performance for NAVIGO 4LV 2D and ARC, respectively. Over 12 months, the global complication-free rate for both leads was 97.1% (95% CI: 93.71% to 98.70%), with a mean pacing capture threshold of 1.23 V±0.73 V and a mean impedance of 951 Ω±300.1 Ω. CONCLUSION: A high implantation success rate and low complication rate was reported for the novel NAVIGO 4LV 2D and ARC leads, along with successful performance up to 12 months.

Characterization of conduction system activation in the postinfarct ventricle using ripple mapping.

BACKGROUND: Three-dimensional (3D) mapping of the ventricular conduction system is challenging. OBJECTIVE: The purpose of this study was to use ripple mapping to distinguish conduction system activation to that of adjacent myocardium in order to characterize the conduction system in the postinfarct left ventricle (LV). METHODS: High-density mapping (PentaRay, CARTO) was performed during normal rhythm in patients undergoing ventricular tachycardia ablation. Ripple maps were viewed from the end of the P wave to QRS onset in 1-ms increments. Clusters of >3 ripple bars were interrogated for the presence of Purkinje potentials, which were tagged on the 3D geometry. Repeating this process allowed conduction system delineation. RESULTS: Maps were reviewed in 24 patients (mean 3112 ± 613 points). There were 150.9 ± 24.5 Purkinje potentials per map, at the left posterior fascicle (LPF) in 22 patients (92%) and at the left anterior fascicle (LAF) in 15 patients (63%). The LAF was shorter (41.4 vs 68.8 mm; P = .0005) and activated for a shorter duration (40.6 vs 64.9 ms; P = .002) than the LPF. Fourteen of 24 patients had left bundle branch block (LBBB), with 11 of 14 (78%) having Purkinje potential-associated breakout. There were fewer breakouts from the conduction system during LBBB (1.8 vs 3.4; 1.6 ± 0.6; P = .039) and an inverse correlation between breakout sites and QRS duration (P = .0035). CONCLUSION: We applied ripple mapping to present a detailed electroanatomic characterization of the conduction system in the postinfarct LV. Patients with broader QRS had fewer LV breakout sites from the conduction system. However, there was 3D mapping evidence of LV breakout from an intact conduction system in the majority of patients with LBBB.

Effects of periodontal treatment on the C-reactive protein levels in hemodialysis patients: A systematic review and meta-analysis.

AIM: This systematic review provides a summary of the scientific evidence concerning effects of periodontal treatment on the C-reactive protein (CRP) levels in hemodialysis patients. MATERIAL AND METHODS: Eight databases were accessed until May 2020 for interventional studies which evaluated CRP levels in hemodialysis patients before and after periodontal treatment. Inclusion criteria were studies involving hemodialysis patients with gingivitis or periodontitis, without restriction of year, language, and publication status. Random effects meta-analysis was performed. The risk of bias in eligible studies was assessed using the Joanna Briggs Institute's Critical Appraisal tools for use in systematic reviews. Certainty of evidence was also evaluated using GRADE approach. RESULTS: The search in the databases resulted in 326 records, from which only seven met the eligibility criteria and therefore were submitted to qualitative evaluation. The meta-analysis revealed that, in general, the reduction in CRP levels had moderate and statistically significant effect size (standardized mean difference [SMD] = 0.45; confidence interval [CI] 95% = 0.25, 0.65; p < .001). Statistical heterogeneity was low (I2  = 0.0%; p = .771). Most studies showed moderate risk of bias. CONCLUSION: Based on low certainty of evidence, the results suggest that periodontal treatment can significantly contribute to reduce CRP levels among hemodialysis patients. However, more randomized clinical studies, with follow-up longer than 12 months, using standardized diagnostic methods and controlling confounding factors, should be performed to strengthen the evidence.

Realized genomic selection across generations in a reciprocal recurrent selection breeding program of Eucalyptus hybrids.

Introduction: Genomic selection (GS) experiments in forest trees have largely reported estimates of predictive abilities from cross-validation among individuals in the same breeding generation. In such conditions, no effects of recombination, selection, drift, and environmental changes are accounted for. Here, we assessed the effectively realized predictive ability (RPA) for volume growth at harvest age by GS across generations in an operational reciprocal recurrent selection (RRS) program of hybrid Eucalyptus. Methods: Genomic best linear unbiased prediction with additive (GBLUP_G), additive plus dominance (GBLUP_G+D), and additive single-step (HBLUP) models were trained with different combinations of growth data of hybrids and pure species individuals (N = 17,462) of the G1 generation, 1,944 of which were genotyped with ~16,000 SNPs from SNP arrays. The hybrid G2 progeny trial (HPT267) was the GS target, with 1,400 selection candidates, 197 of which were genotyped still at the seedling stage, and genomically predicted for their breeding and genotypic values at the operational harvest age (6 years). Seedlings were then grown to harvest and measured, and their pedigree-based breeding and genotypic values were compared to their originally predicted genomic counterparts. Results: Genomic RPAs ≥0.80 were obtained as the genetic relatedness between G1 and G2 increased, especially when the direct parents of selection candidates were used in training. GBLUP_G+D reached RPAs ≥0.70 only when hybrid or pure species data of G1 were included in training. HBLUP was only marginally better than GBLUP. Correlations ≥0.80 were obtained between pedigree and genomic individual ranks. Rank coincidence of the top 2.5% selections was the highest for GBLUP_G (45% to 60%) compared to GBLUP_G+D. To advance the pure species RRS populations, GS models were best when trained on pure species than hybrid data, and HBLUP yielded ~20% higher predictive abilities than GBLUP, but was not better than ABLUP for ungenotyped trees. Discussion: We demonstrate that genomic data effectively enable accurate ranking of eucalypt hybrid seedlings for their yet-to-be observed volume growth at harvest age. Our results support a two-stage GS approach involving family selection by average genomic breeding value, followed by within-top-families individual GS, significantly increasing selection intensity, optimizing genotyping costs, and accelerating RRS breeding.

Association between the number of altered late potential criteria and increased arrhythmic risk in Brugada syndrome patients.

BACKGROUND: Brugada syndrome (BrS) is associated with abnormal electrophysiological properties at right ventricular epicardium, consisting of fragmented electrograms extending well beyond QRS termination. We aimed to evaluate the utility of signal-averaged electrocardiogram (SA-ECG) for the noninvasive assessment of late potentials (LP) and risk stratification of BrS patients. METHODS: A prospective, observational, single-center study of BrS patients is submitted to SA-ECG with the determination of the total filtered QRS duration (fQRS), root mean square voltage of the 40 ms terminal portion of the QRS (RMS40), and duration of the low-amplitude electric potential component of the terminal portion of the QRS (LAS40). LP were considered positive when above standard cut-offs: fQRS > 114 ms, RMS40 < 20 µV, and LAS40 > 38 ms. The rates of malignant arrhythmic events (MAEs), defined as sudden death or appropriate shocks, were compared in relation to clinical characteristics and SA-ECG findings. RESULTS: A total of 106 BrS patients (mean age, 48 ± 12 years, 67.9% male) were studied, 49% with type-1 spontaneous pattern and 81% asymptomatic. During a median follow up of 4.7 years, 10 patients (7.1%) suffered MAEs, including 4 sudden deaths. The presence of LP was significantly associated with the arrhythmic risk, which increased with the number of altered LP criteria. In comparison to the patients who had none or 1 altered LP criterium, MAE risk was 4.7 times higher in those with 2 altered criteria and 9.4 times higher in those with 3 altered LP criteria. CONCLUSIONS: SA-ECG may be a useful tool for risk stratification in BrS. The presence of 2 or 3 abnormal LP criteria could identify a subset of asymptomatic patients at high risk of arrhythmic events.

Sodium nitroprusside as an adjunctive treatment for schizophrenia reduces the Ndel1 oligopeptidase activity.

OBJECTIVE: Schizophrenia (SCZ) is a disabling disorder that continues to defy clinicians and researchers. We investigated the effects of sodium nitroprusside (sNP) in an animal model of SCZ and as an add-on therapy in patients and the relationship between treatment with sNP and activity of the nDel1 enzyme, whose involvement in the pathophysiology of the disorder has been suggested earlier. METHODS: Ndel1 activity was measured following sNP infusions in spontaneously hypertensive rats (SHR; 2.5 or 5.0 mg/kg) and in a double-blind trial with SCZ patients (0.5 µg/kg/min). RESULTS: Ndel1 activity was significantly reduced after sNP infusion in blood of SHR compared to controls, and in patients receiving sNP (t = 7.756, df = 97, p < 0.0001, dcohen = 1.44) compared to placebo. Reduced Ndel1 activity between baseline and the end of the infusion was only seen in patients after treatment with sNP. CONCLUSION: Our findings suggest that SCZ patients may benefit from adjunctive therapy with sNP and that the Ndel1 enzyme is a candidate biomarker of psychopathology in the disorder. Future research should look into the role of Ndel1 in SCZ and the potential effects of sNP and drugs with similar profiles of action in both animals and patients.

Nutritional status in perianal Crohn's disease: are we underestimating the impact?

Symptomatic perianal disease is common in patients with Crohn's disease (CD), and perianal fistulas represent the primary form of anal involvement. This type of involvement is associated with a poor prognosis and a disabling course. The treatment is challenging and involves both surgical and medical approaches. Despite combined therapy, a significant portion of patients may still require proctectomy to control the symptoms. Consequently, investigating factors that may influence the outcome of perianal disease remains a priority area of research in CD. Nutritional deficiencies are well documented among CD patients with luminal forms of involvement and are closely related to poor clinical outcomes, therapy response, and postoperative complications. As a result, leading guidelines recommend regular nutritional assessment and correction of nutritional deficiencies in patients requiring a surgical approach. Despite these recommendations and the high rate of surgeries among CD patients with perianal disease, there is a shortage of studies addressing the real impact of nutritional status on the course and outcomes of perianal disease. This knowledge gap underscores the importance of further research to understand better and improve the management of perianal CD. This narrative review aims to provide an overview of nutritional status assessment and the influence of nutritional status on the outcomes of patients with perianal CD.

Side-Viewing Duodenoscope versus Forward-Viewing Gastroscope for Endoscopic Retrograde Cholangiopancreatography in Billroth II Gastrectomy Patients.

Introduction: Endoscopic retrograde cholangiopancreatography (ERCP) in patients with Billroth II gastrectomy is still a challenging procedure. The optimal approach, namely the type of endoscope and sphincter management, has yet to be defined. Aim: To compare the efficacy and safety of forward-viewing gastroscope and the side-viewing duodenoscope in ERCP of patients with Billroth II gastrectomy. Methods: We conducted a retrospective, single-center cohort study of consecutive patients with Billroth II gastrectomy submitted to ERCP in an expert center for ERCP between 2005 and 2021. The outcomes assessed were: papilla identification, deep biliary cannulation, and adverse events (AEs). Multivariate analysis was performed to evaluate potential associations and predictors of the main outcomes. Results: We included 83 patients with a median age of 73 (IQR 65-81) years. ERCP was performed using side-viewing duodenoscope in 52 and forward-viewing gastroscope in 31 patients. Patients' characteristics were similar in the two groups. The global rate of papilla identification was 66% (n = 55). The rate of deep cannulation was 58% considering all patients and 87% in the subgroup of patients in which the papilla major was identified. Cannulation was performed with standard methods in 65% of cases and with needle-knife fistulotomy in 35%. AEs occurred in 4 patients. There was no difference between duodenoscope and gastroscope in papilla identification (64% [95% CI: 51-77] vs. 71% [55-87]). Although not statistically significant, duodenoscope had a lower deep cannulation rate when considering all patients (52% [15-39] vs. 68% [7-35]) and a higher AEs rate (8% [1-15] vs. 0% [0-1]). In a multivariate analysis, the use of gastroscope significantly increased the deep cannulation rate (OR = 152.62 [2.5-9,283.6]). Conclusion: This study demonstrates that forward-viewing gastroscope is at least as effective and safe as side-viewing duodenoscope for ERCP in patients with Billroth II gastrectomy. Moreover, our study showed that gastroscope is an independent predictor of successful cannulation.

Introdução: Colangiopancreatografia retrógrada endoscópica (CPRE) em doentes submetidos previamente a gastrectomia com reconstrução Billroth II é ainda um exame desafiante. A melhor abordagem, nomeadamente o tipo de endoscópio e a técnica de canulação biliar, ainda não está definida. Objectivo: Comparar a eficácia e segurança do gastroscópio de visão frontal e do duodenoscópio de visão lateral na CPRE de doentes com gastrectomia com reconstrução Billroth II. Métodos: Conduzimos um estudo de coorte retrospectivo e unicêntrico que incluiu consecutivamente doentes com gastrectomia com reconstrução Billroth II submetidos a CPRE num centro de referência para CPRE entre 2005 e 2021. Os outcomes avaliados foram: identificação da papila, canulação biliar profunda e efeitos adversos (EAs). Regressão logística foi realizada para avaliar possíveis associações e preditores dos outcomes. Resultados: Incluímos 83 doentes com uma idade mediana de 73 (IIQ 65­81) anos. A CPRE foi realizada usando duodenoscópio em 52 doentes e usando o gastroscópio de visão frontal em 31 doentes. As características dos doentes foram semelhantes entre os dois grupos. A taxa global de identificação da papila foi de 66% (n = 55). A taxa de canulação profunda foi de 58% considerando todos os doentes e de 87% considerando apenas o subgrupo de doentes nos quais a papila major foi identificada. A canulação foi realizada usando métodos convencionais em 65% e usando fistulotomia com faca em 35% dos doentes. EAs ocorreram em 4 doentes. Não houve diferenças entre duodenoscópio e gastroscópio relativamente à identificação da papila [64% (95% CI: 51­77) vs 71% (55­87)]. Apesar de estatisticamente não significativo, o uso de duodenoscópio teve uma menor taxa de canulação profunda quando considerados todos os doentes [52% (15­39) vs 68% (7­35)] e uma maior taxa de EAs [8% (1­15) vs 0% (0­1)]. Na regressão logística, o uso de gastroscópio significativamente aumentou a taxa de canulação profunda [OR = 152.62 (2.5­9,283.6)]. Conclusão: Este estudo demonstra que o uso de gastroscópio de visão frontal é pelo menos igualmente eficaz e seguro ao duodenoscópio na CPRE de doentes com gastrectomia com reconstrução Billroth II. Para além disso, o nosso estudo demonstrou que o uso de gastroscópio é um predictor independente para canulação.

Jejunal Gastrointestinal Stromal Tumor: A Strange Cause of Massive Gastrointestinal Bleeding.

Jejunal gastrointestinal stromal tumors (GIST) are rare mesenchymal tumors of the gastrointestinal (GI) tract and a rare cause of massive GI bleeding. Due to this rarity and non-specific presentation, diagnosis and treatment may be difficult and often delayed. Urgent surgical intervention is crucial for controlling the source of bleeding and total tumor excision. Herein, we present the case of a 40-year-old male who presented to the emergency room (ER) with features of upper GI bleeding. He referred astheny and black stools, and was pale, sweaty, and tachycardic despite normal blood pressure. Rectal examination revealed melena, and laboratory findings revealed decreased hemoglobin (Hb) and elevated blood urea. Upper endoscopy was normal, and the Hb level dropped again to 6.9 g/dL; therefore, blood transfusion was required during ER observation. For further investigation, the patient underwent an angio-computed tomography scan, which revealed a lesion located in a jejunal loop as the probable bleeding source. Emergency exploratory laparotomy revealed a jejunal loop tumor. Segmental enterectomy containing the tumor was performed and the post-operative period was uneventful. The anatomopathological examination was compatible with low-risk GIST, and the multidisciplinary board agreed that surveillance was the best ongoing treatment. Due to the rarity of jejunal GIST as the cause of massive GI bleeding, diagnosis may be challenging, delaying prompt treatment with bleeding source control. In such cases, surgery may be both lifesaving and curative. Therefore, these tumors should not be forgotten when managing patients with occult GI bleeding with an atypical presentation to prevent delays in treatment and severe outcomes.

An Overview of Robotic Colorectal Surgery Adoption and Training in Brazil.

Background and Objectives: Robotic surgical systems have rapidly become integrated into colorectal surgery practice in recent years, particularly for rectal resections, where the advantages of robotic platforms over conventional laparoscopy are more pronounced. However, as with any technological advancement, the initial high costs can be a limiting factor, leading to unequal health service access, especially in middle- and lower-income countries. Materials and Method: A narrative review was conducted with the objective of providing an overview of the escalating adoption, current training programmes, and certification process of robotic colorectal surgery in Brazil. Results: Brazil has witnessed a rapid increase in robotic platforms in recent years. Currently, there are 106 robotic systems installed nationwide. However, approximately 60% of the medical facilities which adopted robotic platforms are in the Southeast region, which is both the most populous and economically prosperous in the country. The Brazilian Society of Coloproctology recently established clear rules for the training programme and certification of colorectal surgeons in robotic surgery. The key components of the training encompass theoretical content, virtual robotic simulation, observation, assistance, and supervised procedures in colorectal surgery. Although the training parameters are well established, no colorectal surgery residency programme in Brazil has yet integrated the teaching and training of robotic surgery into its curriculum. Thus far, the training process has been led by private institutions and the industry. Conclusion: Despite the fast spread of robotic platforms across Brazil, several challenges still need to be addressed to democratise training and promote the widespread use of these platforms. It is crucial to tackle these obstacles to achieve greater integration of robotic technology in colorectal surgery throughout the country.

Epigenetic dynamics during capacitation of naïve human pluripotent stem cells.

Human pluripotent stem cells (hPSCs) are of fundamental relevance in regenerative medicine. Naïve hPSCs hold promise to overcome some of the limitations of conventional (primed) hPSCs, including recurrent epigenetic anomalies. Naïve-to-primed transition (capacitation) follows transcriptional dynamics of human embryonic epiblast and is necessary for somatic differentiation from naïve hPSCs. We found that capacitated hPSCs are transcriptionally closer to postimplantation epiblast than conventional hPSCs. This prompted us to comprehensively study epigenetic and related transcriptional changes during capacitation. Our results show that CpG islands, gene regulatory elements, and retrotransposons are hotspots of epigenetic dynamics during capacitation and indicate possible distinct roles of specific epigenetic modifications in gene expression control between naïve and primed hPSCs. Unexpectedly, PRC2 activity appeared to be dispensable for the capacitation. We find that capacitated hPSCs acquire an epigenetic state similar to conventional hPSCs. Significantly, however, the X chromosome erosion frequently observed in conventional female hPSCs is reversed by resetting and subsequent capacitation.

Aesthetic results were more satisfactory after oncoplastic surgery than after total breast reconstruction according to patients and surgeons.

INTRODUCTION: Patient satisfaction after breast cancer surgery has an impact on body image, sexual function, self-esteem, and quality of life and may differ from the perception of the attending physician. This study aimed to compare the aesthetic outcomes and satisfaction with conservative oncoplastic surgeries, mastectomies, and total breast reconstruction. METHODS: We included 760 women diagnosed with invasive breast carcinoma or phyllodes tumors who returned at least 6 months after surgery or radiotherapy at two public hospitals and a private clinic between 2014 and 2022. Data was collected prospectively from patients and retrospectively from their medical records using a specific form after obtaining their informed consent. Aesthetic outcomes and quality of life were assessed using the BREAST-Q©, Harris Scale, and BCCT.core software. Data were evaluated using the SPSS statistical software. Statistical significance was set at p < 0.05. This study was approved by the hospital ethics committees. RESULTS: A total of 405 (53.29%) partial and 355 (46.71%) total reconstructions were included. Patients who underwent partial reconstruction were older and had higher body mass index. Patients who underwent total reconstruction had larger tumors with advanced clinical and pathological stages. Clinical and surgical complications occurred more frequently in the total reconstruction group. A greater number of reparative surgeries and lipofilling procedures were required for total reconstruction. According to the BREAST-Q, the partial reconstruction group showed significantly higher levels of women's satisfaction with their breasts, the surgical outcomes, psychosocial and sexual well-being, provision of information, and the reconstructive surgeon. Only physical well-being was slightly higher in the total reconstruction group. In most cases, the results were rated good or excellent. Physicians considered partial reconstructions to have better results than total reconstructions, although this difference was not perceived by the BCCT.core software. CONCLUSION: Women who underwent partial breast reconstruction had higher levels of satisfaction in several domains, lower frequency of complications, and required fewer surgeries to complete their reconstruction than women who underwent total reconstruction. Physicians were also more satisfied with the results of partial reconstructions.

Nursing Interventions for Patients With Neurogenic Bowel Dysfunction Arising From Complete Spinal Cord Injury: A Scoping Review.

PURPOSE: We mapped key concepts and identified 4 fundamental nursing interventions for patients with neurogenic bowel dysfunction due to complete spinal cord injury (SCI). METHODS: A scoping review was conducted according to the recommendations of the Joanna Briggs Institute. SEARCH STRATEGY: Searches were performed in PubMed, LILACS, CINAHL, COCHRANE, and SCOPUS electronic databases. We use searched the gray literature using the Google Scholar search engine. We formulated a question to guide the search, based on the participants, concept, and context format: "What are the key manual nursing interventions performed in patients with neurogenic bowel dysfunction resulting from complete spinal cord injury?" We included nursing intervention strategies that may be performed by health professionals, patients, or caregivers. Two reviewers independently participated in the selection; disagreements were resolved by a third reviewer and 5 experts. FINDINGS: Thirteen studies conducted between 1998 and 2019 were selected; 5 were randomized clinical trials. Four main interventions were identified for conservative management of neurogenic bowel dysfunction in patients with complete SCI. They were digital-anal stimulation, manual extraction of feces, abdominal massage, and strategies used to stimulate the gastrocolic reflex. CONCLUSIONS: Research suggests that each of these interventions, administered alone or in combination, supports bowel evacuation in patients with a complete SCI. Each of these interventions may be performed by a nurse, and taught to the patient and/or lay caregiver. IMPLICATIONS FOR PRACTICE: An individualized bowel management program for patients with neurogenic bowel dysfunction due to SCI is necessary to ensure regular bowel evacuation, preserve fecal continence, and support dignity and health-related quality of life. The conservative interventions identified in this scoping review should be incorporated in protocols or guidelines for management of neurogenic bowel dysfunction in this vulnerable population.

Buerger's Disease - A Clinical Case.

Buerger's disease is a distal segmental nonatherosclerotic vasculopathy that involves the inferior and superior limbs of smoker males younger than 45 years old. This article aims to describe a clinical case and revise the literature about Buerger's disease. A 45-year-old smoker male repeatedly visited the emergency department for refractory pain and inflammatory signs in the right hallux. After developing ulcers in the right foot, Doppler ultrasonography revealed segmental occlusion of distal arteries of that limb. It was also observed in arteriography "corkscrew" collaterals. Autoimmune, thrombophilic and cardiovascular diseases were excluded. Analgesia, antibiotics and alprostadil were implemented. As a result, the patient stopped smoking and was submitted to minor amputation with complete healing, after which he remained asymptomatic. Buerger's disease is a diagnosis of exclusion. Therefore, smoking cessation is the most effective treatment and is crucial to prevent disease progression.
