Impact of Transplantation Timing on Renal Graft Survival Outcomes and Perioperative Complications

Nighttime organ transplantation aims to decrease cold ischemia duration, yet conflicting data exists on its impact on graft function and perioperative complications. This multicenter TRANSPLANT'AFUF study including 2,854 patients, transplanted between 1 January 2011, and 31 December 2022, investigated nighttime kidney transplantation's impact (8:00 p.m.-8:00 a.m.) versus daytime (8:00 a.m.-8:00 p.m.) on surgical complications and graft survival. Overall, 2043 patients (71.6%) underwent daytime graft, while 811 (28.4%) underwent nighttime graft. No impact was observed of timing of graft surgery on graft survival with a median survival of 98 months and 132 months for daytime and nightime grafting, respectively (p = 0.1749). Moreover, no impact was observed on early surgical complications (Clavien I-II = 20.95% for DG and 20.10% for NG; Clavien III-IV-V = 15.42% for DG and 12.94% for NG; p = 0.0889) and late complications (>30 days) (Clavien I-II = 6.80% for DG and 5.67% for NG; Clavien III-IV-V = 12.78% for DG and 12.82% for NG; p = 0.2444). Noteworthy, we found a significant increase in Maastricht 3 donors' rates in nighttime transplantation (5.53% DG vs. 21.45% NG; p < 0.0001). In conclusion, nighttime kidney transplantation did not impact early/late surgical complications nor graft survival.

Unleashing the mysterious link between COVID-19 and a famous childhood vasculitis: Kawasaki disease

Background

Coronavirus disease 2019 (COVID-19) emerged as a small outbreak in Wuhan rapidly progressing into the deadliest pandemic since the Spanish flu of 1918. The disease was deemed trivial in children, until the reporting, few days ago, of an emerging pediatric multi-inflammatory syndrome mimicking Kawasaki disease (KD).

Main body

This report reveals that coronaviridae were implicated in induction of several post-infectious vasculitides, namely, KD, AHEI, and HSP. This occurs in genetically susceptible individuals to vascular inflammation. Shared genetic susceptibilities between KD and CoV include genes encoding for CD 40, HLAB-15:03, and ACE. This leads to augmented inflammation with hypersecretion of cytokines especially IL-6.

Conclusion

The revealed relationships between KD and CoV can help to predict the risk of KD in COVID-19 patients through screening levels of upregulated cytokines. It might also signify that classic treatment of KD with IVIG might need to be replaced with anti-cytokine therapy in COVID-19 patients.

[The third dimension of the face aging, improvement of its understanding]

OBJECTIVES

Over the past 30 years, surface imaging has made tremendous progress. Surgical management has also been subject of numerous technical and strategic developments. For a better understanding of the curative strategies of face aging, the authors have put into perspective the three-dimensional data acquired up to date.

METHOD

A review of the literature focused on the three-dimensional study of facial aging was carried out.

RESULTS

Thanks to the precision of new surface acquisition systems and larger patient cohorts, our understanding of surfaces and volumes is now much more accurate. 3D, particularly highlights the major impact of aging on the perioral area, which was up to now neglected compared to other facial areas.

CONCLUSION

A technical discussion is needed to identify the best techniques to correct the defects and provide a natural result for those anatomical areas that are heavily impacted by aging but not corrected in the final.

Depression and the risk of autoimmune disease: a nationally representative, prospective longitudinal study

BACKGROUND

Autoimmune diseases are associated with substantial morbidity and mortality, yet the etiology remains unclear. Depression has been implicated as a risk factor for various immune-related disorders but little is known about the risk of autoimmune disease. This study examined the association between depression and the risk of autoimmune disease, and investigated the temporal and dose-response nature of these relationships.

METHOD

A prospective population-based study including approximately 1.1 million people was conducted using linked Danish registries. Depression and autoimmune diseases were diagnosed by physicians and documented in medical records. In total, 145 217 individuals with depression were identified between 1995 and 2012. Survival analyses were used to estimate the relative risk of autoimmune disease among those with, compared to without, depression. Analyses were adjusted for gender, age, and co-morbid mental disorders.

RESULTS

Depression was associated with a significantly increased risk of autoimmune disease [incidence rate ratio (IRR) 1.25, 95% CI 1.19-1.31], compared to those without a history of depression. Results suggest a general increased risk of autoimmune diseases following the onset of depression during first year (IRR 1.29, 95% CI 1.05-1.58), which remained elevated for the ensuing 11 years and beyond (IRR 1.53, 95% CI 1.34-1.76). Findings did not support a dose-response relationship.

CONCLUSIONS

Depression appears to be associated with an increased risk of a range of autoimmune diseases. Depression may play a role in the etiology of certain autoimmune conditions. If replicated, findings could highlight additional clinical implications in the treatment and management of depression. Future studies are needed to investigate the possible social, genetic, and neurobiological underpinnings of these relationships.

Effects of a culturally informed intervention on abused, suicidal African American women

This study examined (a) the relative efficacy of a culturally sensitive empowerment group intervention (Nia) aimed at increasing 3 protective factors-self-esteem, hopefulness, and effectiveness of obtaining resources-versus treatment as usual (TAU) for low-income, abused African American women who recently had attempted suicide and (b) the impact of participants' readiness to change with regard to their abusive relationship and suicidal behavior on their levels of each protective factor in the 2 conditions. The sample included 89 African American women who reported intimate partner violence (IPV) exposure and a recent suicide attempt. Multivariate general linear modeling revealed that those in Nia showed greater improvements in self-esteem, but not in hopefulness or effectiveness of obtaining resources. However, significant interactions emerged in which participants who were "less ready to change" (i.e., earlier in the stages of change process) their IPV situation and suicidal behavior endorsed greater levels of hopefulness and perceived effectiveness of obtaining resources, respectively, following Nia. Findings suggest that abused, suicidal African American women who are more reluctant initially to changing their abusive situation and suicidal behavior may benefit from even a brief, culturally informed intervention.

Big five personality factors and cigarette smoking: a 10-year study among US adults

The present study examined the relation between the big five personality traits and any lifetime cigarette use, progression to daily smoking, and smoking persistence among adults in the United States (US) over a ten-year period. Data were drawn from the Midlife Development in the US (MIDUS) I and II (N = 2101). Logistic regression was used to examine the relationship between continuously measured personality factors and any lifetime cigarette use, smoking progression, and smoking persistence at baseline (1995-1996) and at follow-up (2004-2006). The results revealed that higher levels of openness to experience and neuroticism were each significantly associated with increased risk of any lifetime cigarette use. Neuroticism also was associated with increased risk of progression from ever smoking to daily smoking and persistent daily smoking over a ten-year period. In contrast, conscientiousness was associated with decreased risk of lifetime cigarette use, progression to daily smoking, and smoking persistence. Most, but not all, associations between smoking and personality persisted after adjusting for demographic characteristics, depression, anxiety disorders, and substance use problems. The findings suggest that openness to experience and neuroticism may be involved in any lifetime cigarette use and smoking progression, and that conscientiousness appears to protect against smoking progression and persistence. These data add to a growing literature suggesting that certain personality factors--most consistently neuroticism--are important to assess and perhaps target during intervention programs for smoking behavior.

Childhood maltreatment and the persistence of smoking: a longitudinal study among adults in the US

The current study examined the relationship between childhood maltreatment-emotional, physical, and severe physical maltreatment-and the initiation and persistence of smoking. Data were drawn from the Midlife Development in the United States (MIDUS) Survey Waves 1 and 2. Frequency of childhood emotional, physical, and severe physical maltreatment (never, rare, intermittent, frequent) reported at Wave 1 was examined in relation to ever smoking, smoking daily, and persistent daily smoking at Waves 1 and 2. Logistic regression analyses were used to calculate odds ratios (with 95% confidence intervals), which were then adjusted for potential confounders. Childhood emotional, physical, and severe physical maltreatment were associated with increased odds of ever smoking, smoking daily, and persistent smoking at Waves 1 and 2. The majority of these associations remained significant after adjusting for confounding variables. These results suggest a history of trauma may play a prominent role in recalcitrant cigarette smoking and suggest that the success rates of treatments for smoking cessation may be improved by integrating trauma treatment where appropriate.

Anxiety disorders and risk of self-reported ulcer: a 10-year longitudinal study among US adults

OBJECTIVE

Previous epidemiologic studies have documented a link between anxiety disorders and ulcer among adults. Few studies have examined these associations over time and little is understood about the pathways underlying these relationships.

METHOD

Data were drawn from n = 2101 adult participants in the Midlife Development in the United States I and II. Data on ulcer diagnoses were collected through self-report: among participants in the current sample, 38 reported ulcer at Waves 1 and 2 (prevalent ulcer), and 18 reported ulcer at Wave 2 but not at Wave 1 (incident ulcer). Panic attacks and generalized anxiety disorder at Wave 1 (1994) were examined in relation to prevalent (past 12 months) and incident ulcer approximately 10 years later at Wave 2 (2005).

RESULTS

Anxiety disorders at Wave 1 were associated with increased prevalence of ulcer [odds ratio (OR) = 4.1, 95% confidence interval (CI) = 2.0-8.4], increased risk of incident ulcer at Wave 2 (OR = 4.1, 95% CI = 1.4-11.7) and increased risk of treated ulcer at Wave 2 (OR = 4.7, 95% CI = 2.3-9.9) compared with those without anxiety.

CONCLUSIONS

In this large population sample of adults, anxiety disorders were associated with an increased risk of ulcer over a 10-year period. These relationships do not appear to be explained by confounding or mediation by a wide range of factors. Future studies should address potential mechanisms underlying the relationship between anxiety and ulcer.

A 10-year prospective study of respiratory disease and depression and anxiety in adulthood

BACKGROUND

Several cross-sectional studies have found an association between respiratory disease and increased mood or anxiety disorders among adults. Little is known about the nature of these associations over time or the role of potential confounders in these links.

OBJECTIVES

To investigate the association between respiratory disease and incident and persistent depression or anxiety disorders 10 years later and to examine potential pathways of these associations.

METHODS

Data were drawn from the Midlife Development in the United States survey, a representative sample of adults in the United States ages 18 to 74 years. Participants (N = 2,101) were interviewed on a range of health domains at baseline at wave 1 (1994) and again at wave 2 (2005).

RESULTS

Respiratory disease was associated with increased odds of depression and anxiety disorders cross-sectionally at both time points. Respiratory disease at wave 1 was not associated with incident depression or anxiety disorders at wave 2. Respiratory disease at wave 1 was associated with increased odds of persistent depression or anxiety disorders 10 years later among those with depression or anxiety disorders at wave 1. Associations were not explained by differences in demographic characteristics, secondhand smoke exposure, cigarette smoking, or history of exposure to childhood maltreatment.

CONCLUSION

Findings shed new light on the association between respiratory disease and depression or anxiety disorders. Individuals with respiratory disease appear to have higher prevalence of concurrent depression or anxiety disorders and persistent depression or anxiety disorders compared with those without respiratory disease. However, a history of respiratory disease does not appear to confer increased risk of new onset of depression or anxiety disorders.

Hookah use among college students: prevalence, drug use, and mental health

BACKGROUND

There is consistent evidence that hookah use is as, if not more, harmful than cigarette use. Yet, hookah users underestimate the potential deleterious effects of hookah use. This study examined the rates of hookah use and associated demographic characteristics in a sample of undergraduates at a small Northeastern university. This study also examined the relationships between hookah use and other substance use, mental health problems, and perceived levels of stress.

METHODS

Data were drawn from the Spring 2009 American Health Association-National College Health Assessment (ACHA-NCHA) at one small, Northeastern university (N=1799). The relationships between hookah use and other substance use, mental health problems, and perceived stress levels were examined using logistic regression analyses.

RESULTS

Hookah use (in the past month) was reported among 14.1% (253/1799) of this sample of undergraduates. Hookah users were more likely to use other substances, including cigarettes, cannabis, alcohol, cocaine, and amphetamines. The strongest associations emerged between hookah use and alcohol and cigarette use. There were no significant associations found between hookah use and any mental health problems or perceived stress levels.

CONCLUSIONS

Hookah users are significantly more likely to use other substances, including alcohol, cigarettes, cannabis, cocaine, and amphetamines compared with non-hookah users. In contrast to cigarette smoking, hookah use does not appear to be associated with mental health problems or perceived stress levels in this sample of undergraduates. Further investigation into the prevalence and correlates of hookah use is needed in representative population samples.

Global health benefits of being raised in a rural setting: results from the National Comorbidity Survey

AIM

The aim of this study was to examine the association between being raised in a rural setting and physical and mental health among adults in the USA.

METHODS

Data were drawn from the National Comorbidity Survey (n = 8098), a household probability sample representative of adults aged 15-54 years in the USA. Multiple logistic regression analyses were used to determine the association between being raised in a rural area and the likelihood of mental disorders, physical disorders, suicide behavior, and parental mental health. Odds ratios (OR) with 95% confidence intervals were calculated, adjusting for differences in demographic characteristics.

RESULTS

Being raised in a rural setting was associated with decreased odds of ulcer (OR = 0.56 [0.34, 0.91]). Mental disorders (any lifetime) (OR = 0.74 [0.64, 0.85]), any anxiety disorder (OR = 0.75 [0.6, 0.92]) and any substance use disorder (OR = 0.79 [0.65, 0.94]) were significantly less likely among adults who were raised in a rural setting. Maternal psychopathology and exposure to trauma were significantly lower among those raised in a rural setting, compared with those who were not. These relations were not explained by sociodemographic differences.

CONCLUSIONS

These data provide preliminary evidence that being raised in a rural environment lowers the risk of mental and physical health problems in adulthood. Being raised in a rural community also appears to be associated with significantly lower likelihood of exposure to trauma and maternal psychopathology. Future studies that can identify potential protective factors and mechanisms underlying these pathways are needed next.

Symptoms of alcohol dependence and smoking initiation and persistence: a longitudinal study among US adults

BACKGROUND

A large number of adults report symptoms of, but do not meet diagnostic criteria for, an alcohol use disorder. Yet, little is known about the relationship between symptoms of alcohol use disorders and the initiation and persistence of smoking. This study prospectively examines the relationship between having 1-2 symptoms of alcohol dependence (without abuse) and smoking initiation and persistence as well as nicotine dependence over a 3-year period among adults in the United States.

METHODS

Data were drawn from Wave 1 (2001-2002) and Wave 2 (2004-2005) of the National Epidemiologic Survey on Alcohol and Related Conditions. Relationships between Wave 1 symptoms of alcohol dependence, alcohol abuse, and alcohol dependence and initiation and persistence of cigarette smoking and nicotine dependence at Wave 2 were examined using logistic regression analyses. Analyses were adjusted for demographics, mood and anxiety disorders.

RESULTS

Symptoms of alcohol dependence were associated with smoking initiation at Wave 2. There was no association between symptoms of alcohol dependence and smoking persistence. Symptoms of alcohol dependence predicted incident and persistent nicotine dependence. Findings persisted after adjusting for demographic characteristics and mood/anxiety disorders.

CONCLUSIONS

Even 1-2 symptoms of alcohol dependence are associated with increased vulnerability to smoking initiation and onset and persistence of nicotine dependence at a similar strength as alcohol use disorders. Efforts at smoking cessation must address problematic alcohol use, even at the subclinical level, in order to improve efficacy.

Understanding the Link Between Multiple Oppressions and Depression Among African American Women

The purpose of our study was to examine the multiple oppression experiences of sexual objectification, racism, and gendered racism as predictors of depressive symptoms among a clinical sample of low-income African American women. In addition, we examined coping with oppression via internalization (i.e., the tendency to attribute responsibility or the cause of an oppressive event to oneself) as a mediator between these three intersecting forms of oppression and depressive symptoms. Participants included 144 African American women who sought some type of mental health treatment at a U.S. southeastern, public, urban, university-affiliated hospital that attends to a primarily indigent and underserved population. The results of our mediational analysis using bootstrapping provided support for a theorized model in which coping with oppressive events via internalization mediated the links between sexual objectification and depression and between racist events and depression but not between gendered racism and depression. In addition, a unique and direct effect of racist events on depression was found. Finally, the four variables in the model accounted for 42% of variance in depression scores. The study includes implications for future research and clinical work such as exploration of other mediators and the importance of comprehensive intake assessments and multicultural/feminist coping interventions.

Racial identity and reasons for living in African American female suicide attempters

The current study investigated the association between racial identity and reasons for living in African American women who have attempted suicide. Particular attention was paid to the relation between two elements of racial identity (private regard, racial centrality) and reasons for living, an alternative assessment of suicidal risk. While private regard refers to an individual's beliefs about the African American race, racial centrality describes the importance an individual places on his or her racial identity. The sample included 82 low-income African American women, ages 18-64, who reported a suicide attempt in the past 12 months. Participants, recruited from a large, urban public hospital located in the Southeast, completed the Reasons for Living Inventory and the Multidimensional Inventory of Black Identity, which included the private regard and racial centrality subscales. Results indicated that, as predicted, higher private regard was associated with more reasons for living. Contrary to expectations, racial centrality was not correlated with reasons for living nor was there an interaction between private regard and racial centrality indicating that racial centrality did not function as a moderator in predicting participants' reasons for living scores. Implications for culturally competent clinical interventions that target bolstering private regard are discussed.

Médiatisation et «greffe de visage» ou «à qui appartient la greffe de visage»?

Mediatisation of a scientific event could be neither controlled, nor verifiable. The experience which has been lived through the first worldwide allotransplantation of composite tissues of the face confirms that the actors of a surgical innovation are not the owners. Because there is neither confidentiality nor possible patent. Curiously the scientific world, providing with a sharing ethic, which rightly privileges the free spreading of knowledge in the way that most people could benefit of it. Obviously it is made without denied controversy, for truth as purpose. This scientific word that way joins the media one, with a specific ethic of the duty of information, but also interested in mercantile preoccupations quick to cultivate controversy not to enlighten this truth but to better sell pictures or papers. Than the author should only sustain this instrumentation which could certainly flatter him, and from which he could used, but in reality that paralysed him a little to go on in serenity with his shadow worker way.

Effect of a clinical pathway on the hospitalisation rates of children with asthma: a prospective study

AIM

To determine the effect of implementing a clinical pathway, using evidence-based clinical practice guidelines, for the emergency care of children and adolescents with asthma.

METHODS

A prospective, before-after, controlled trial was conducted, which included patients aged 1-18 years who had acute exacerbations of asthma treated in a tertiary care paediatric emergency department. Data were collected for identical 2-month seasonal periods before and after implementation of the clinical pathway to determine hospitalisation rate and other outcomes. For 2 weeks after emergency visits, the rate at which patients returned to emergency care for worsening asthma was evaluated. A multidisciplinary panel, using national guidelines and a systematic review, developed the pathway.

RESULTS

267 patients were studied. The rate of hospitalisation was significantly lower in the post-implementation group (10/74; 13.5%) than in the pre-implementation control group (53/193; 27.5%; p = 0.02; number needed to treat 7.1). All reduction in hospitalisation occurred in children with moderate to severe asthma exacerbation. After implementation of the clinical pathway, the rate of administration of oral corticosteroids to patients with moderate or severe exacerbations increased from 71% to 92% (p = 0.01), and significantly more patients received beta2-agonists in the first hour (p = 0.02). No significant change in relapse to acute care occurred within 2 weeks (p = 0.19).

CONCLUSIONS

An evidence-based clinical pathway for children and adolescents with moderate to severe exacerbations of acute asthma markedly decreases their rate of hospitalisation without increased return to emergency care.

Comparison of two computerassisted surgery techniques to guide a mandibular distraction osteogenesis procedure Technical note

The accuracy of distracted facial bone displacement depends on the preoperative clinical assessment, surgical planning and technique. The aim of this study was to evaluate two different techniques to guide the mandibular distraction surgical procedure using an intraoral device. This study was performed on a fresh cadavre. 3D reconstructions from a computed tomographic (CT) acquisition were used for the two techniques. The first technique comprised a customised stereolithographic template and the second technique used a computer-assisted surgery (CAS) unit to guide the osteotomy and the positioning and screwing of the distractor device. Both methods were planned and compared with the same 3D software. The authors discuss the feasibility and reliability of the two techniques. The accuracy of the two techniques appears to be comparable for clinical applications, although the rapid prototyping template technique appears to be more satisfactory.

Three-dimensional imaging of the petrous bone for the middle fossa approach to the internal acoustic meatus: an experimental study

The goal of this study was to highlight the feasibility of creating three-dimensional (3D) pictures of the petrous bone from a routine CT examination which can be used for a middle fossa approach to the internal acoustic meatus, in order to secure this operation. The surgical aim is to reach the roof of the internal acoustic meatus directly without injuring the adjacent functional structures of the petrous bone. Two heads of embalmed cadavers were scanned every millimeter with a slice thickness of 1 mm centered on the petrous bones. The horizontal reference was the Frankfurt line and the frontal and sagittal planes were perpendicular to this line. This method is similar to routine examinations for surgical patients. The pictures were first loaded on an optical disk, then into a computer (Silicon Graphics System). Amira software was used to create 3D pictures. The anatomy of the temporal bone could easily be identified, notably the surgical landmarks of the middle fossa approach. Three-dimensional computer-assisted imaging can reveal the anatomy of the petrous bone in a realistic view. The main anatomic structures for a middle fossa approach can be recognized easily. This realistic view may be very useful for surgeons, and 3D images deserve to be developed further.

[Orthognathic surgery and stereolithographic models. A new technic of dental occlusion transfer]

Use of stereolithographic models in orthognathic surgery is limited by the difficult in considering the facial osteotomies and the dental occlusion at the same time. Different techniques allow the surgeon to perform the simulation using composite prototypes after including the dental casts on the models. These techniques require complex "stereotaxic" systems or a surgical approach before CT scanning in order to insert the reference screws. They cannot overcome the problem of mandibular movement during the CT session. Our technique is a simple way to include the dental casts in the stereolithographic model with high precision. This can easily be done in a maxillo-facial environment and does not require any further special knowledge other than that which can be aquired in a classical dental laboratory. The occlusion transfer is achieved with a silicon cast of the teeth and the bony structures of the sterolithographic model on which we include the plaster dental casts. The silicone cast of the dental occlusion can also be used to decrease the mandibular movement during CT scanning.

[Microsurgery and ballistic traumatology of the face]

The use of free flaps to fill and repair facial defects due to suicidal gunshot wounds has considerably extended and refined the possibilities available to reconstructive surgeon. The objective is no longer to close the defect at any cost, or "fill a hole", but to replace missing tissue by an identical tissue, able to restore an identical cosmetic appearance, support equivalent constraints, and restore analogous function. Retrospective analysis of 56 cases of large facial defects due to gunshot wounds revealed a total of 66 free flaps for 32 cases. The vascular quality of the flaps allowed better integration in a sometimes hostile recipient site and markedly reduced the treatment time. Although the objective results obtained in the treatment of these severe defects remain poor, the first-line use of these multiple flaps, exclusively reserved for deep repair, as the basis for reconstruction, has modified our behaviour. A real medium-term treatment strategy, based on a decision flow-chart, can be proposed which, despite several inevitable failures, leaves less room for improvisation and piecemeal surgery. Free flaps are only the hidden part of the reconstruction, as surface cover uses local flaps and other conventional reconstructive surgery techniques. However, this humble, hidden role is nevertheless fundamental, in the strict sense of the term, and guides the general approach to this surgery.
