RESUMO

OBJECTIVES: We aimed to evaluate the risk of procedural complications after TAVR using secondary radial access (RA) versus femoral access (FA) through a systematic review and meta-analysis of the published literature. BACKGROUND: Transcatheter aortic valve replacement (TAVR) entails both large-bore arterial access for device delivery and secondary arterial access for hemodynamic and imaging assessments. It is unknown whether RA versus FA for this secondary access reduces the risk of procedural complications. METHODS: We searched PubMed, Embase, the Cochrane Library, and Web of Science for observational studies comparing TAVR procedural complications in RA versus FA. Event rates were compared via weighted summary odds ratios using the Mantel-Haenszel method. RESULTS: Six manuscripts encompassing 6132 patients were included. Meta-analysis showed that RA reduced the risk of major vascular complications (OR 0.58, 95% CI 0.43-0.77, p < 0.001, I2 0%) and major/life-threatening bleeding (OR 0.46, 95% CI 0.36-0.59, p < 0.001, I2 0%) as compared to FA for secondary TAVR access. We also observed a reduction 30-day mortality (OR 0.55, 95% CI 0.38-0.79, p = 0.001, I2 0%), acute kidney injury (OR 0.45, 95% CI 0.34-0.60, p < 0.001, I2 0%), and stroke and transient ischemic attack (OR 0.43, 95% CI 0.27-0.67, p < 0.001, I2 0%). CONCLUSIONS: RA reduced the risk of major vascular and bleeding complications when compared to FA for secondary access in TAVR. RA is associated with reduced risk of other adverse outcomes including mortality, but these associations may be related to selection bias and confounding given the observational study designs.

RESUMO

Gestational surrogacy in the United States has quadrupled since 1999, but to date, only a few states explicitly permit compensated gestational surrogacy. Current legal prohibitions are often influenced by outdated and stereotyped understandings of surrogacy. It is increasingly important to understand the current literature about the medical and mental health impacts of surrogacy and how state legislatures have addressed compensated gestational surrogacy in recent years. Based on this review, we found no evidence of substantial adverse medical or psychological outcomes among women who are gestational carriers or among the children they give birth to. The literature suggests that gestational surrogacy is a safe and increasingly popular option for families as long as rigorous screening and medical, psychological, and social supports are equitably provided. As states move to responsibly legalize and regulate gestational surrogacy, there is a continued need for further longitudinal studies on the health and psychological outcomes of gestational surrogacy.

RESUMO

We present the case of a male infant with violaceous bullae on the scalp that were initially thought to be bullous aplasia cutis but at 3 months of age were diagnosed as a kaposiform hemangioendothelioma. This diagnosis should be considered when evaluating newborns with bullous plaques on the scalp that do not heal in the first 2-3 weeks of life. Kaposiform hemangioendothelioma (KHE) is a rare vascular tumor that typically presents as a violaceous to purpuric plaque at birth or early infancy. It may be associated with Kasabach-Merritt phenomenon (KMP), a potentially life-threatening consumptive coagulopathy.

RESUMO

PURPOSE: To determine the relation between glucose metabolic changes of the primary visual cortex, structural abnormalities of the corresponding visual tracts, and visual symptoms in children with Sturge-Weber syndrome (SWS). MATERIALS AND METHODS: In 10 children with unilateral SWS (ages 1.5-5.5 years), a region-of-interest analysis was applied in the bilateral medial occipital cortex on positron emission tomography (PET) and used to track diffusion-weighted imaging (DWI) streamlines corresponding to the central visual pathway. Normalized streamline volumes of individual SWS patients were compared with values from age-matched control groups as well as correlated with normalized glucose uptakes and visual field deficit. RESULTS: Lower glucose uptake and lower corresponding streamline volumes were detected in the affected occipital lobe in 9/10 patients, as compared to the contralateral side. Seven of these 9 patients had visual field deficit and normal or decreased streamline volumes on the unaffected side. The two other children had no visual symptoms and showed high contralateral visual streamline volumes. There was a positive correlation between the normalized ratios on DWI and PET, indicating that lower glucose metabolism was associated with lower streamline volume in the affected hemisphere (R = 0.70, P = 0.024). CONCLUSION: We demonstrated that 18F-flurodeoxyglucose (FDG)-PET combined with DWI tractography can detect both brain damage on the side of the lesion and contralateral plasticity in children with early occipital lesions.

RESUMO

Reconstruction of bony craniofacial defects requires precise understanding of the anatomic relationships. The ideal reconstructive technique should be fast as well as economical, with minimal donor-site morbidity, and provide a lasting and aesthetically pleasing result. There are some circumstances in which a patient's own tissue is not sufficient to reconstruct defects. The development of sophisticated software has facilitated the manufacturing of patient-specific implants (PSIs). The aim of this study was to analyze the utility of polyether ether ketone (PEEK) PSIs for craniofacial reconstruction. We performed a retrospective chart review from July 2009 to July 2013 in patients who underwent craniofacial reconstruction using PEEK-PSIs using a virtual process based on computer-aided design and computer-aided manufacturing. A total of 6 patients were identified. The mean age was 46 years (16-68 y). Operative indications included cancer (n = 4), congenital deformities (n = 1), and infection (n = 1). The mean surgical time was 3.7 hours and the mean hospital stay was 1.5 days. The mean surface area of the defect was 93.4 ± 43.26 cm(2), the mean implant cost was $8493 ± $837.95, and the mean time required to manufacture the implants was 2 weeks. No major or minor complications were seen during the 4-year follow-up. We found PEEK implants to be useful in the reconstruction of complex calvarial defects, demonstrating a low complication rate, good outcomes, and high patient satisfaction in this small series of patients. Polyether ether ketone implants show promising potential and warrant further study to better establish the role of this technology in cranial reconstruction.

RESUMO

BACKGROUND: Electroconvulsive therapy (ECT) is a widely used, highly effective antidepressant treatment. Except for the most severely ill patients, right unilateral (RUL) electrode placement is the most frequent initial treatment choice. In current practice, RUL ECT is administered at several multiples of seizure threshold (ST) based on reports that lower stimulus intensity results in lower response/remission rates. Many patients, as part of an initial dose titration to determine ST, will receive a single treatment with low-dose RUL ECT and subsequent treatments with a stimulus at a multiple of ST. OBJECTIVE: To assess response to the first ECT. METHODS: A retrospective analysis of charts from clinical practice at Mount Sinai Medical Center was performed. RESULTS: A single treatment with low-dose (presumably near ST) RUL ECT had a significant and immediate antidepressant effect in our sample of patients with major depression. We determined that this response is similar to that of patients receiving a single initial treatment with high-dose RUL ECT (at a multiple of ST). CONCLUSIONS: These data suggest, contrary to commonly held belief, that RUL ECT may be effective at a low stimulus dose. This argues against restimulating at 6 times ST in the initial session, based on the belief that the near-threshold seizure has no antidepressant efficacy. Our findings suggest a need for further investigation of cases in which low-dose RUL ECT may be an effective antidepressant treatment. Further prospective studies, including larger numbers of patients who receive randomized treatment with low- or high-dose RUL with longer follow-up, are indicated.

RESUMO

Hypoplastic left heart syndrome (HLHS) is a congenital heart disease where the left ventricle is reduced in size. A forward genetic screen in mice identified SIN3A associated protein 130 kDa (Sap130), part of the chromatin modifying SIN3A/HDAC complex, as a gene contributing to the etiology of HLHS. Here, we report the role of zebrafish sap130 genes in heart development. Loss of sap130a, one of two Sap130 orthologs, resulted in smaller ventricle size, a phenotype reminiscent to the hypoplastic left ventricle in mice. While cardiac progenitors were normal during somitogenesis, diminution of the ventricle size suggest the Second Heart Field (SHF) was the source of the defect. To explore the role of sap130a in gene regulation, transcriptome profiling was performed after the heart tube formation to identify candidate pathways and genes responsible for the small ventricle phenotype. Genes involved in cardiac differentiation and cardiac function were dysregulated in sap130a, but not in sap130b mutants. Confocal light sheet analysis measured deficits in cardiac output in MZsap130a supporting the notion that cardiomyocyte maturation was disrupted. Lineage tracing experiments revealed a significant reduction of SHF cells in the ventricle that resulted in increased outflow tract size. These data suggest that sap130a is involved in cardiogenesis via regulating the accretion of SHF cells to the growing ventricle and in their subsequent maturation for cardiac function. Further, genetic studies revealed an interaction between hdac1 and sap130a, in the incidence of small ventricles. These studies highlight the conserved role of Sap130a and Hdac1 in zebrafish cardiogenesis.

RESUMO

Hypoplastic left heart syndrome (HLHS) is a congenital heart disease where the left ventricle is reduced in size. A forward genetic screen in mice identified SIN3A associated protein 130kDa ( Sap130 ), a protein in the chromatin modifying SIN3A/HDAC1 complex, as a gene contributing to the digenic etiology of HLHS. Here, we report the role of zebrafish sap130 genes in heart development. Loss of sap130a, one of two Sap130 orthologs, resulted in smaller ventricle size, a phenotype reminiscent to the hypoplastic left ventricle in mice. While cardiac progenitors were normal during somitogenesis, diminution of the ventricle size suggest the Second Heart Field (SHF) was the source of the defect. To explore the role of sap130a in gene regulation, transcriptome profiling was performed after the heart tube formation to identify candidate pathways and genes responsible for the small ventricle phenotype. Genes involved in cardiac differentiation and cell communication were dysregulated in sap130a , but not in sap130b mutants. Confocal light sheet analysis measured deficits in cardiac output in MZsap130a supporting the notion that cardiomyocyte maturation was disrupted. Lineage tracing experiments revealed a significant reduction of SHF cells in the ventricle that resulted in increased outflow tract size. These data suggest that sap130a is involved in cardiogenesis via regulating the accretion of SHF cells to the growing ventricle and in their subsequent maturation for cardiac function. Further, genetic studies revealed an interaction between hdac1 and sap130a , in the incidence of small ventricles. These studies highlight the conserved role of Sap130a and Hdac1 in zebrafish cardiogenesis.

RESUMO

Background: Critical care trainees were integral in the coronavirus disease (COVID-19) pandemic response. Several perspective pieces have provided insight into the pandemic's impact on critical care training. Surveys of program directors and critical care trainees have focused on curricular impact. There is a lack of data from the trainee perspective on curricular enhancements, career development, and emotional and well-being needs to succeed in a critical care career in the ongoing COVID-19 pandemic. Objective: Our objective was to elicit perspectives from critical care trainees on their personal and professional needs as they continue to serve in the COVID-19 pandemic. Methods: This was a hypothesis-generating qualitative study. Individuals in a U.S. critical care training program during the COVID-19 pandemic participated in either focus groups or semistructured interviews. Interviews were conducted between July 2020 and March 2021 until data saturation was achieved. Audio recordings were professionally transcribed and analyzed using qualitative content analysis. A codebook was generated by two independent coders, with a third investigator reconciling codes when there were discrepancies. Themes and subthemes were identified from these codes. Results: Thirteen participants were interviewed. The major themes identified were as follows: 1) Curricular adaptation is necessary to address evolving changes in trainee needs; 2) COVID-19 impacted career development and highlighted that trainees need individualized help to meet their goals; 3) receiving social support at work from peers and leaders is vital for the sustained well-being of trainees; 4) fostering and maintaining a sense of meaning and humanity in one's work is important; and 5) trainees desire assistance and support to process their emotions and experiences. Conclusion: The needs expressed by critical care trainees are only partially captured in conceptual models of physician well-being. The need for multilevel workplace social networks and identifying meaning in one's work have been magnified in this pandemic. The themes discussing curricular gaps, career development needs, and skills to process work-related trauma are less well captured in preexisting conceptual models and point to areas where further research and intervention development are needed.

RESUMO

For any given level of overall adiposity, individuals vary considerably in fat distribution. The inherited basis of fat distribution in the general population is not fully understood. Here, we study up to 38,965 UK Biobank participants with MRI-derived visceral (VAT), abdominal subcutaneous (ASAT), and gluteofemoral (GFAT) adipose tissue volumes. Because these fat depot volumes are highly correlated with BMI, we additionally study six local adiposity traits: VAT adjusted for BMI and height (VATadj), ASATadj, GFATadj, VAT/ASAT, VAT/GFAT, and ASAT/GFAT. We identify 250 independent common variants (39 newly-identified) associated with at least one trait, with many associations more pronounced in female participants. Rare variant association studies extend prior evidence for PDE3B as an important modulator of fat distribution. Local adiposity traits (1) highlight depot-specific genetic architecture and (2) enable construction of depot-specific polygenic scores that have divergent associations with type 2 diabetes and coronary artery disease. These results - using MRI-derived, BMI-independent measures of local adiposity - confirm fat distribution as a highly heritable trait with important implications for cardiometabolic health outcomes.

RESUMO

Gene mutations causing loss of dystrophin result in the severe muscle disease known as Duchenne muscular dystrophy (DMD). Despite efforts at genetic repair, DMD therapy remains largely palliative. Loss of dystrophin destabilizes the sarcolemmal membrane, inducing mechanosensitive cation channels to increase calcium entry and promote cell damage and, eventually, muscle dysfunction. One putative channel is transient receptor potential canonical 6 (TRPC6); we have shown that TRPC6 contributed to abnormal force and calcium stress-responses in cardiomyocytes from mice lacking dystrophin that were haplodeficient for utrophin (mdx/utrn+/- [HET] mice). Here, we show in both the HET mouse and the far more severe homozygous mdx/utrn-/- mouse that TRPC6 gene deletion or its selective pharmacologic inhibition (by BI 749327) prolonged survival 2- to 3-fold, improving skeletal and cardiac muscle and bone defects. Gene pathways reduced by BI 749327 treatment most prominently regulated fat metabolism and TGF-ß1 signaling. These results support the testing of TRPC6 inhibitors in human trials for other diseases as a novel DMD therapy.

RESUMO

Trigeminal neuralgia, historically dubbed the "suicide disease," is an exceedingly painful neurologic condition characterized by sudden episodes of intense facial pain. Unfortunately, the only U.S. Food and Drug Administration (FDA)-approved medication for trigeminal neuralgia carries substantial side effects, with many patients requiring surgery. Here, we identify the NRF2 transcriptional network as a potential therapeutic target. We report that cerebrospinal fluid from patients with trigeminal neuralgia accumulates reactive oxygen species, several of which directly activate the pain-transducing channel TRPA1. Similar to our patient cohort, a mouse model of trigeminal neuropathic pain also exhibits notable oxidative stress. We discover that stimulating the NRF2 antioxidant transcriptional network is as analgesic as inhibiting TRPA1, in part by reversing the underlying oxidative stress. Using a transcriptome-guided drug discovery strategy, we identify two NRF2 network modulators as potential treatments. One of these candidates, exemestane, is already FDA-approved and may thus be a promising alternative treatment for trigeminal neuropathic pain.

RESUMO

The American Society of Plastic Surgery recently recorded a decline in numbers of breast reductions, one of the most common procedures performed by plastic surgeons. The purpose of this study is to characterize the reduction mammoplasty patient population which would further assist in planning the future workforce needs. Using the Nationwide Inpatient Sample database for 2007, a χ analysis of female in-patients treated with reduction mammoplasty for breast hypertrophy was performed to identify significant differences in race and payer mix. Of 8394 female in-patients with breast hypertrophy, 61% were treated with reduction mammoplasty. Black and Hispanic patients (P < 0.0001) and patients with private insurance (P < 0.0001) were more likely to undergo reduction mammoplasty. This study demonstrates racial and socioeconomic disparities in breast reduction in the United States in 2007. With the pending institution of universal healthcare, it is predicted that disparities revealed may worsen due to cost containment pressures.

RESUMO

Cannabis use is increasingly prevalent. Cannabinoid receptors regulate pro-inflammatory cytokines, and compounds in marijuana exert diverse physiologic effects. As more patients use cannabis, clinicians should recognize implications of perioperative cannabis use. Although the role of cannabis use in perioperative pain control has been explored, little is known about its effect on perioperative wound healing or on hematologic, pulmonary, and cardiovascular physiology. METHODS: We searched PubMed for English-language articles related to cannabis (ie, marijuana, cannabidiol oil, and tetrahydrocannabinol) and wound healing, cardiovascular, pulmonary, or hematologic outcomes, and surgery. Titles and abstracts were reviewed, and relevant articles were analyzed. Human, animal, and pathology studies were included. Editorials, case reports, and review articles were excluded. RESULTS: In total, 2549 wound healing articles were identified; 5 human studies and 8 animal/pathology studies were included. Results were conflicting. An estimated 2900 articles related to cardiovascular effects were identified, of which 2 human studies were included, which showed tetrahydrocannabinol and marijuana caused tachycardia. A total of 142 studies regarding pulmonary effects were identified. Three human studies were included, which found no difference in respiratory complications. In total, 114 studies regarding hematologic effects were identified. The 3 included human studies found conflicting venous thromboembolism risks. The overall study quality was poor. Information about dose/duration, administration route, and follow-up was reported with variable completeness. CONCLUSIONS: Surgeons should consider effects of cannabis in the perioperative setting. Little is known about its perioperative effects on wound healing, or on cardiovascular, pulmonary, and hematologic physiology. Further research should elucidate the effects of administration route, dose, and timing of cannabis use among surgical patients.

RESUMO

OBJECTIVE: This open-label 12-week study was conducted to evaluate the efficacy and safety of tofacitinib, a JAK inhibitor, in treatment-refractory active dermatomyositis (DM). METHODS: Tofacitinib in extended-release doses of 11 mg was administered daily to 10 subjects with DM. Prior to treatment, a complete washout of all steroid-sparing agents was performed. The primary outcome measure was assessment of disease activity improvement based on the International Myositis Assessment and Clinical Studies group definition of improvement. Response rate was measured as the total improvement score according to the 2016 American College of Rheumatology (ACR)/European League Against Rheumatism (EULAR) myositis response criteria. Secondary outcome measures included Cutaneous Dermatomyositis Disease Area and Severity Index (CDASI) scores, chemokine levels, immunohistochemical analysis of STAT1 expression in the skin, RNA sequencing analysis, and safety. RESULTS: At 12 weeks, the primary outcome was met in all 10 subjects. Five (50%) of 10 subjects experienced moderate improvement in disease activity, and the other 50% experienced minimal improvement according to the 2016 ACR/EULAR myositis response criteria. The secondary outcome of the mean change in the CDASI activity score over 12 weeks was statistically significant (mean ± SD 28 ± 15.4 at baseline versus 9.5 ± 8.5 at 12 weeks) (P = 0.0005). Serum chemokine levels of CXCL9/CXCL10 showed a statistically significant change from baseline. A marked decrease in STAT1 signaling in association with suppression of interferon target gene expression was demonstrated in 3 of 9 skin biopsy samples from subjects with dermatomyositis. The mean ± SD level of creatine kinase in the 10 subjects at baseline was 82 ± 34.8 IU/liter, highlighting that disease activity was predominantly located in the skin. CONCLUSION: This is the first prospective, open-label clinical trial of tofacitinib in DM that demonstrates strong clinical efficacy of a pan-JAK inhibitor, as measured by validated myositis response criteria. Future randomized controlled trials using JAK inhibitors should be considered for treating DM.

RESUMO

INTRODUCTION: Craniosynostosis is the premature fusion of 1 or more of the cranial sutures, which causes an abnormal skull shape. The treatment is complex and requires surgical intervention for correction, between 3 and 12 months of age. The current standard for diagnosing craniosynostosis is to obtain a computed tomographic (CT) scan. However, recent studies have emphasized potential problems associated with ionizing radiation. The aim of this study was to evaluate the use of the preoperative CT scan, and its findings, and to define the value of these data. MATERIALS AND METHODS: This study is a retrospective analysis of 89 patients with craniosynostosis during the period between 1998 and 2007, who had CT using the Yale-New Haven Hospital computer system. Clinical findings such as age, sex, and diagnosis were recorded. All intraoperative abnormalities were noted. Preoperative CT scans were reevaluated for accuracy and completeness of diagnosis, cerebral anomalies, and other head and neck pathologic conditions. RESULTS: Initially, 131 cases of nonsyndromic craniosynostosis were identified. Of these, we had access to CT evaluations in 89 patients. The mean age at the time of the surgery was 13 months, varying from 2 months to 18 years old. Most patients were males. The most common diagnoses were sagittal synostosis in 47 cases; unilateral coronal, 16; and metopic, 15. In most patients, the CT scan demonstrated the same diagnosis as the clinical examination-derived diagnosis. However, 6 patients had an incomplete diagnosis or misdiagnosis. In addition, 3 cases of prominence of the subarachnoid space, 2 cases of cerebral atrophy, 1 case of subarachnoid tumor, and 1 deformational dysplasia of encephalon were identified. Other minor additional diagnoses were 5 cases of fluid in the middle ear and antrum of mastoid, 2 cases of cysts in the maxilla, and 1 case of an associated cervical lymphatic tumor. CONCLUSIONS: The advantage of CT use is greater accuracy in diagnosis, less potential for inappropriate surgery, and, as an ancillary effect, a more complete and timely assessment of congenital anomalies so that more appropriate referrals can be made. Low-dose (pediatric) radiation CT still seems to have a place in the examination of a patient with skull deformity and potential craniosynostosis.

RESUMO

With 1 in 3 women affected, accounting for one billion women worldwide, Violence Against Women (VAW) constitutes one of the widest reaching human rights violations globally. Although the forms they take may vary, these abuses are not confined to a single social class, geographic region, or culture. Existing studies have yet to describe the full burden of abuse that asylum-seeking women endure throughout their lifetimes. We describe a novel coding tool that classifies types of abuse, identifies abuse perpetrators, and estimates how long and how often each abuse was experienced. The authors used this tool to describe and categorize the abuses endured by 85 cisgender, adult women seeking asylum in the United States who presented to the Weill Cornell Center for Human Rights for forensic medical evaluations from 2013 to 2017. We reviewed a total of 180 legal and forensic medical affidavits that were written in support of the applicants' asylum claims. Using the coding tool, we identified each abuse, classified every perpetrator, and, whenever possible, estimated how long and how frequently each abuse was endured. Interpretations of the raw data contained in this article and a discussion of their significance can be found in our associated publication: "Gender-Based Violence experienced by Women Seeking Asylum in the United State: A Lifetime of Multiple Traumas Inflicted by Multiple Perpetrators" [1]. The coding instrument described herein characterizes VAW by classifying the narrative data that are included in interviews, focus groups, medical records, and the like. Our coding instrument is the first of its kind to describe all types and severities of violence endured by women, classify the perpetrators of that violence, and delineate the timeline of violence over each individual's life. We hope that this holistic approach to classifying and describing VAW will enable other research groups to examine untested or unrealized associations between victims, perpetrators, and abuses. Ultimately, obtaining more complete data will empower us to advocate more effectively and to design more comprehensive care for victims of VAW.

RESUMO

Estimates by the World Health Organization indicate that 1 in 3 women-more than one billion people worldwide-have experienced some form of Gender-Based Violence (GBV). Violence Against Women (VAW) is a prominent subset of GBV, defined by the United Nations as any act "that results in, or is likely to result in, physical, sexual, or mental harm or suffering to women, including threats of such acts, coercion or arbitrary deprivation of liberty, whether occurring in public or in private life." VAW can include verbal harassment, physical abuse, sexual abuse, honor killing, and femicide and can occur at the hands of individuals, institutions, or states. Whereas numerous studies have documented the multiple forms of physical, sexual, and psychological violence experienced by women, a thorough characterization of the abuses experienced by asylum-seeking women in the United States has not yet been undertaken. Our analysis of the affidavits for 85 cisgender, female asylum seekers who applied for forensic medical evaluations through a student-run asylum clinic, reveals a life-long pattern of multiple types of VAW inflicted by multiple perpetrators. These findings have implications for the focus of the medico-legal documentation submitted in support of female asylum seekers as well as for the design of comprehensive healthcare services for women and girls who are granted relief.

RESUMO

INTRODUCTION: Optimum timing of postoperative showering varies. Earlier showering improves patient satisfaction, but the impact of the timing of showering on postoperative infection is unclear. We conducted a systematic literature review and meta-analysis to investigate the outcomes of various postoperative showering practices. METHODS: We searched PubMed to identify relevant human clinical studies in English, and searched these for additional references. Articles were reviewed for patient demographics, surgical specialty and procedure, wound closure method, placement of drains, showering protocol, and rates of infection and complications. Only randomized controlled trials were analyzed. A random-effects meta-analysis model was used to determine overall infection and complication rates between patients allowed to shower within the first 48 h postoperatively or later. RESULTS: Out of 357 studies, seven and five were included in the infection and complications rate meta-analyses, respectively. A total of 1,881 and 958 patients were included in each analysis; 605 and 477 patients in each analysis were allowed to shower on or before postoperative day 2 ("early"), while the remainder were prohibited from showering until postoperative day 3 to beyond one week ("delayed") postoperatively. There was no difference in infection (p = 0.45, [-0.0052, 2 × 0.007 95% CI]) or complication rate (p = 0.36, [-0.0046, 2 × 0.005 95% CI]) with earlier vs. delayed showering protocols. CONCLUSION: Published literature demonstrates no increase in the overall rate of wound infections or complications when patients showered earlier in the postoperative period. Additional randomized studies are needed to determine the ideal time for postoperative showering. These data should be considered by surgeons while determining when to permit patients to shower after surgery.
