Survival of Elderly Patients Undergoing Pancreatoduodenectomy in an Integrated Health System.

INTRODUCTION: The purpose of this study is to examine pancreatoduodenectomy (PD) perioperative outcomes and consider how age may be related to overall survival in an integrated health system. MATERIALS AND METHODS: A retrospective review was performed of 309 patients who underwent PD between December 2008 and December 2019. Patients were divided into two groups: aged 75 y or less and more than 75 y, defined as senior surgical patients. Univariate and multivariable analyses of predictive clinicopathologic factors associated with overall survival at 5 y were performed. RESULTS: In both groups, the majority underwent PD for malignant disease. The proportion of senior surgical patients alive at 5 y was 33.3% compared to 53.6% of younger patients (P = 0.003). There were also statistically significant differences between the two groups with respect to body mass index, cancer antigen 19-9, Eastern Cooperative Oncology Group performance status, and Charlson comorbidity index. On multivariable analysis, disease type, cancer antigen 19-9, hemoglobin A1c, length of surgery, length of stay, Charlson comorbidity index, and Eastern Cooperative Oncology Group performance status were found to be statistically significant factors for overall survival. Age was not significantly related to overall survival on multivariable logistic regression and when the analysis was limited to pancreatic cancer patients. CONCLUSIONS: Although the difference in overall survival between patients aged less than and more than 75 years was significant, age was not an independent risk factor for overall survival on multivariable analysis. Rather than a patient's chronological age, his/her physiologic age including medical comorbidities and functional status may be more correlated to overall survival.

Foot Melanoma Localized to Subungual Toe Location Portends Poorer Prognosis.

Our group previously reported that melanoma of the foot is associated with advanced disease on diagnosis and decreased survival. Lesions localized to the toe appeared to have the worst outcomes. In this study, we both expanded our study to include a 10-year population of patient with invasive melanoma of the foot and ankle and investigated additional factors associated with prognosis. Between January 2007 and December 2016, 211 patients underwent biopsy diagnosis and surgery for invasive melanoma in the BLANK health care system. Demographic, pathologic, staging, and localization characteristics were studied for overall survival. Lesions were localized to dorsal foot, plantar foot, toe (nonsubungual), and toe (subungual) locations. Multivariable analysis found Breslow depth, ulceration, lymph node involvement, and subungual toe location to be associated with poorer survival. Overall survival rate for foot melanoma was 70.6%. Overall survival for nonsubungual toe melanoma was 60.7%, compared to 53.1% for subungual toe melanoma. Of the subungual melanomas, 37.5% of presented as deep lesions with a Breslow depth >4.0 mm. Subungual melanoma was statistically significant for and found to be an independent prognostic factor associated with poorer survival and advanced disease. Based on the results of this study, there should be a low threshold to biopsy suspicious lesions of the toe and foot with particular attention to be dedicated to subungual lesions.

Pancreaticogastrostomy as a fistula mitigating strategy for a high-risk pancreatic anastomosis following pancreaticoduodenectomy.

BACKGROUND: Clinically relevant postoperative pancreatic fistula (CR-POPF) following pancreaticoduodenectomy (PD) has been associated with soft gland texture and/or small pancreatic duct. We hypothesized that selective use of pancreaticogastrostomy (PG) over pancreaticojejunostomy (PJ) in those scenarios would decrease the rate of CR-POPF. METHODS: Review of prospective database of all PD's performed at a single institution between 2009 and 2019 was performed. The pancreatic remnant was deemed "high risk" if soft gland and/or small duct were present. RESULTS: PJ was performed in 199 (147 "low-risk" and 52 "high-risk") cases, and 110 patients (all "high-risk") had a PG. Overall CR-POPF rate was 11.9% with no difference between the groups. Risk-stratified analysis within PJ group showed CR-POPF rate of 5.4% versus 36% in "low-risk" versus "high risk" scenarios, respectively; the use of PG significantly decreased CR-POPF rate (9.1%, p < 0.0001). Gastrointestinal bleeding was more likely to occur following PG than PJ. Soft gland texture and gastrointestinal bleeding were the strongest predictors of CR-POPF in PJ and PG groups, respectively. CONCLUSION: Selective use of PG after PD in "high-risk" scenarios mitigates the risk of CR-POPF. Increased rate of gastrointestinal bleeding calls for further refinement of the technique and heightened postoperative vigilance.

Predicting early discharge and readmission following pancreaticoduodenectomy [S079].

INTRODUCTION: Implementing enhanced recovery after surgery (ERAS) protocols for major abdominal surgery has been shown to decrease length of stay (LOS) and postoperative complications, including mortality and readmission. Little is known to guide which patients undergoing pancreaticoduodenectomy (PD) should be eligible for ERAS protocols. METHODS AND PROCEDURES: A retrospective chart review of all PD performed from 2010 to 2018 within an integrated healthcare system was conducted. A predictive score that ranges from 0 to 4 was developed, with one point assigned to each of the following: obesity (BMI > 30), operating time > 400 min, estimated blood loss (EBL) > 400 mL, low- or high-risk pancreatic remnant (based on the presence of soft gland or small duct). Chi-squared tests and ANOVA were used to assess the relationship between this score and LOS, discharge before postoperative day 7, readmission, mortality, delayed gastric emptying (DGE), and pancreatic leak/fistula. RESULTS: 291 patients were identified. Mean length of stay was 8.5 days in those patients who scored 0 compared to 16.2 days for those who scored 4 (p = 0.001). 30% of patients who scored 0 were discharged before postoperative day 7 compared to 0% of those who scored 4 (p = 0.019). Readmission rates for patients who scored 0 and 4 were 12% and 33%, respectively (p = 0.017). Similarly, postoperative pancreatic fistula occurred in 2% versus 25% in these groups (p = 0.007). CONCLUSION: A simple scoring system using BMI, operating time, EBL, and pancreatic remnant quality can help risk-stratify postoperative PD patients. Those with lower scores could potentially be managed via an ERAS protocol. Patients with higher scores required longer hospitalizations, and adjunctive therapy such as medication and surgical technique to decrease risk of delayed gastric emptying and pancreatic fistula could be considered.

Histology of ex vivo skin after treatment with fractionated picosecond Nd:YAG laser in high and low-energy settings.

Background: The fractionated picosecond laser produces microscopic lesions in the epidermis and dermis, which are known as laser-induced optical breakdown (LIOB) and intra-dermal laser-induced cavitation (LIC). There have been multiple histological reports on these phenomena, although some have been challenged on the grounds of similarity to artifacts. Asian skins, with a higher melanin content, may react differently to this treatment, and present literature is also lacking in this area.Purpose: To observe and report the histological effect of different energy levels and parameters of the fractional 532 nm/1064 nm picosecond laser on Asian skin ex vivo.Methods: Six skin samples were taken from clinically normal-looking perilesional areas and treated with different energy levels and parameters of the fractional 532 nm/1064 nm picosecond laser. The specimens were then sent to the lab for H&E staining, and the slides were reviewed by a dermatopathologist.Results: Superficial, intra-epidermal LIOBs were seen in skin treating at higher laser energies; deep, intra-dermal LICs were seen in skin treated at lower energies. Lesion sizes and depths were consistent with previously reported values on Caucasian skins, and lesions were spaced in 600-µm intervals or its multiple.Conclusions: The histological findings are consistent with results from other ethnicities, and the spacing of lesions is a strong indication of their validity as LIOBs or LICs.

Consensus on Changing Trends, Attitudes, and Concepts of Asian Beauty.

BACKGROUND: Asians increasingly seek non-surgical facial esthetic treatments, especially at younger ages. Published recommendations and clinical evidence mostly reference Western populations, but Asians differ from them in terms of attitudes to beauty, structural facial anatomy, and signs and rates of aging. A thorough knowledge of the key esthetic concerns and requirements for the Asian face is required to strategize appropriate facial esthetic treatments with botulinum toxin and hyaluronic acid (HA) fillers. METHODS: The Asian Facial Aesthetics Expert Consensus Group met to develop consensus statements on concepts of facial beauty, key esthetic concerns, facial anatomy, and aging in Southeastern and Eastern Asians, as a prelude to developing consensus opinions on the cosmetic facial use of botulinum toxin and HA fillers in these populations. RESULTS: Beautiful and esthetically attractive people of all races share similarities in appearance while retaining distinct ethnic features. Asians between the third and sixth decades age well compared with age-matched Caucasians. Younger Asians' increasing requests for injectable treatments to improve facial shape and three-dimensionality often reflect a desire to correct underlying facial structural deficiencies or weaknesses that detract from ideals of facial beauty. CONCLUSIONS: Facial esthetic treatments in Asians are not aimed at Westernization, but rather the optimization of intrinsic Asian ethnic features, or correction of specific underlying structural features that are perceived as deficiencies. Thus, overall facial attractiveness is enhanced while retaining esthetic characteristics of Asian ethnicity. Because Asian patients age differently than Western patients, different management and treatment planning strategies are utilized.

A Consensus on Minimizing the Risk of Hyaluronic Acid Embolic Visual Loss and Suggestions for Immediate Bedside Management.

BACKGROUND: Hyaluronic acid fillers have a satisfactory safety profile. However, adverse reactions do occur, and rarely intravascular injection may lead to blindness. Currently there is no internationally recognized consensus on the prevention or management of blindness from hyaluronic acid filler. OBJECTIVES: The authors sought to give guidance on how to minimize the risk and optimize the management of this rare but catastrophic adverse reaction. METHODS: A multinational group of experts in cosmetic injectables from multiple disciplines convened to review current best practice and develop updated consensus recommendations for prevention and bedside intervention if visual loss occurs after cosmetic injection of hyaluronic acid filler. RESULTS: The consensus group provided specific recommendations focusing on the consenting process, prevention, and early management of visual impairment related to intravascular hyaluronic acid filler injection. CONCLUSIONS: Although visual loss due to filler injections is rare, it is important that both patient and physician be aware of this risk. In this paper the authors describe methods and techniques available to reduce the risk and also document suggested initial management should a clinician find themselves in this situation.

HA Filler Injection and Skin Quality-Literature Minireview and Injection Techniques.

Aging of the face produces many changes in the structure and integrity of the skin and other anatomical aspects, the three major signs of which are volume loss, sagginess, and skin quality change. Through surgical or nonsurgical procedures, it is possible to slow or even reverse these mechanisms through artificial means, including thread lifting, radiofrequency, or filler injection. Filler injections are particularly popular in recent years, owing to their convenience, efficacy, and long-lasting results. In this minireview, the author outlines the basic mechanisms behind facial aging, discusses current literature on each aspect of facial aging, and offers injection protocol recommendations based on past literature and clinical experience.

Noninvasive Atrophic Acne Scar Treatment in Asians With a 755-nm Picosecond Laser Using A Diffractive Optic Lens-A Retrospective Photographic Review.

BACKGROUND: The diffractive lens of the picosecond laser is relatively new, and there are few reports on its efficacy in treating atrophic acne scars, especially in Asian populations. OBJECTIVE: Evaluating the efficacy of diffractive lens 755-nm picosecond laser for atrophic acne scar treatment in Asians. PATIENTS AND METHODS: Forty-two patients who were treated for facial atrophic acne scars at a private dermatological clinic were enrolled in this retrospective analysis. Mean session count was 4.28. Before and after photographs were assessed by 2 blinded dermatologists, who rated the amount of overall skin quality improvement on a 5-point scale. RESULTS: All patients experienced improvements in scar texture and overall skin quality after 2 to 6 sessions, with scores of +1.4, 1.45, 1.7, 1.33, 2.3, and 1.66 points after 2, 3, 4, 5, 6, and >6 treatments, respectively. There were no obvious adverse effects after treatment. The postinflammatory hyperpigmentation (PIH) risk was 4.7% (2 of 42, both spontaneously resolved). CONCLUSION: The 755-nm diffractive lens picosecond laser showed good efficacy and low PIH rates when treating atrophic acne scars in darker skin-type patients. In addition to treatment results, additional improvements in overall skin quality and pigmentation make the picosecond laser an effective and desirable treatment option for Asians.

Validated Assessment Scales for the Female Asian Calf.

BACKGROUND: Clinical photonumeric scales have been developed and validated to objectively measure the effectiveness of aesthetic treatments in specific anatomical areas; however, these are based on the typical features of Caucasian patients. No clinical scale for Asian calf appearance currently exists. OBJECTIVE: To develop and validate a calf assessment scale for use in the female Asian patient population. METHODS AND MATERIALS: During 2 validation sessions, 13 raters assessed calf images of female Asian subjects (N = 35) viewed from behind with feet flat on the floor (at rest) and on tiptoes (dynamic). Images were rated from 0 (very slim, linear profile) to 4 (very severe convex profile). RESULTS: Inter-rater and intra-rater reliability were "substantial" (≥0.6, intraclass correlation coefficient [ICC] and weighted kappa) for the calf-at rest, calf-dynamic, and calf summary score. Reliability was "substantial" for calf-at rest and calf-dynamic (≥0.6, ICC and weighted kappa) and "almost perfect" (0.85) for the calf summary score. BMI and calf circumference were highly correlated with scale ratings, and calf circumference was a significant predictor. CONCLUSION: This new photonumeric assessment scale has value for assessing the female Asian calf, providing a standardized measure of calf appearance in clinical practice and clinical research settings.

A Validated Assessment Scale for Asian Chin Projection.

BACKGROUND: As the number of different aesthetic treatments increase, numerous photonumeric assessment scales have been developed and validated to measure the effectiveness of these new treatments and techniques. Photonumeric rating scales have been developed to objectively assess improvements in anatomical areas; however, these have been based on the features of Caucasian patients. OBJECTIVE: To develop and validate a Chin Projection Scale for use in the female Asian patient population. METHODS AND MATERIALS: During 2 validation sessions, 13 raters assessed full frontal and lateral facial views of 50 Asian subjects and also estimated their age and the aesthetic treatment effort required for each subject. Chin projection was rated on a scale from 0 (optimal) to 4 (very severely receding). RESULTS: Inter-rater reliability was 0.80 (substantial) for Validation Session 1 and 0.83 (almost perfect) for Validation Session 2. The results for Estimated Age and Estimated Treatment Effort were essentially the same. CONCLUSION: This study demonstrated the validity of the first photonumeric assessment scale for assessing the appearance of the female Asian chin. This new scale will provide a standardized measure of chin projection for Asian patients in clinical practice and clinical research settings.

Validation of a Photonumeric Assessment Scale for Grading the Slope of the Asian Forehead.

BACKGROUND: As the number of aesthetic treatments has grown, so have the number of photonumeric assessment scales used to compare the effectiveness of these aesthetic treatments in specific anatomical areas; however, these are primarily based on Caucasian features. OBJECTIVE: To assess the validity of the first aesthetic scale for assessing the slope of the Asian forehead. A secondary objective was to correlate this scale with subject demographics and baseline characteristics. METHODS: During 2 validation sessions, 13 raters assessed full frontal and lateral facial images of female (n = 28; 56.0%) and male (n = 22; 44%) subjects. For each subject, the severity of forehead sloping was graded from 0 (convex forehead, optimal forehead volume) to 4 (concave forehead, very severe sloping). Raters also assessed the age of each subject and the estimated aesthetic treatment effort required to treat each subject. RESULTS: Inter-rater reliability was "substantial" with scores of 0.67 and 0.68 for the first and second validation sessions, indicating high reliability. BMI showed the highest correlation with the scale and was a significant predictor in the final regression model. CONCLUSION: This photonumeric assessment scale will be useful for assessing the slope of the Asian forehead in both clinical and research settings.

Melanoma of the Foot Is Associated With Advanced Disease and Poorer Survival.

The purpose of the present study was to review the outcomes and assess the prognostic factors associated with foot melanoma. We hypothesized that primary melanoma of the foot would be more likely to present at an advanced stage and be associated with poorer outcomes. Both univariate and multivariate analyses were conducted to examine the relationships between patients' demographic, clinical, and pathologic characteristics and deaths within 5 years. Categorical data were summarized as frequencies and percentages and continuous variables as mean ± standard deviation. The primary outcome measure was overall survival. On univariate analysis, the significant prognostic variables found included Breslow thickness, ulceration, sentinel node positivity, and localized presentation on the toe. Age, sex, and race were not prognostically significant in this model. Multivariate Cox proportional hazards analysis resulted in a model of foot melanoma with ulceration and location on the toe as independent prognostic variables. The 5-year survival rate for melanoma of the toe was 50%. The results of the present study have shown that physicians should have a low threshold to biopsy suspicious lesions of the foot and ankle. Advanced disease and poorer survival were noted with toe melanoma. An ulcerative lesion of the foot was also associated with poorer survival.

First Consensus on Primary Prevention and Early Intervention in Aesthetic Medicine.

BACKGROUND: Facial aging is a complex interplay of extrinsic and intrinsic factors leading to progressive changes in the skin, subcutaneous tissue, and bone. Clinical experience suggests that early aesthetic intervention may slow the signs of aging, but treatment in the absence of symptoms or with minimal signs of aging has not yet been properly addressed. OBJECTIVES: To provide treatment recommendations for primary prevention and early intervention in individuals with no or minimal signs of aging. METHODS: Fourteen specialists in aesthetic medicine convened over a full-day meeting under the guidance of a certified moderator. RESULTS: Tailored treatment recommendations have been provided for prevention and early intervention of fine wrinkles, static lines and folds, irregular pigmentation, laxity, and subcutaneous volume loss by protecting the epidermis, stimulating neocollagenesis, reducing hyperkinetic musculature, and reinforcing supporting structures. CONCLUSION: Preventive measures and early therapeutic interventions that may alter the course of facial aging were defined. Further studies are needed to support these recommendations with the best possible evidence.

Communication Concepts for Prevention and Early Intervention in Aesthetic Medicine: Consensus and Literature Review.

BACKGROUND: Communication concepts relating to prevention and early intervention (P&E) within aesthetic medicine are poorly understood and highly underexplored. However, effective communication is a key criterion for successful outcomes. OBJECTIVES: To introduce the framework for P&E communication strategies within a younger population and explore the barriers that may be encountered. METHODS: A literature review on P&E communication strategies in aesthetic medicine and related topics of interest was conducted and used to construct a working framework that may be applied in clinical practice. RESULTS: Examination of existing literature revealed a need for a more structured communication framework for P&E encompassing up-to-date evidence-based learning and educational marketing that is tailored to individual needs and target populations. Message framing-the way in which a message is presented-is an important consideration in the dissemination of information to promote changes in health behaviour. A structured consultation is key to optimising patient engagement and ensures a tailored approach to understanding and catering to the specific needs of each patient. CONCLUSION: This is the first paper to discuss the communication concepts behind P&E within aesthetic medicine and paves the way for further research and focus in this significant field.

Automated CT Analysis of Body Composition as a Frailty Biomarker in Abdominal Surgery.

Importance: Prior studies demonstrated consistent associations of low skeletal muscle mass assessed on surgical planning scans with postoperative morbidity and mortality. The increasing availability of imaging artificial intelligence enables development of more comprehensive imaging biomarkers to objectively phenotype frailty in surgical patients. Objective: To evaluate the associations of body composition scores derived from multiple skeletal muscle and adipose tissue measurements from automated segmentation of computed tomography (CT) with the Hospital Frailty Risk Score (HFRS) and adverse outcomes after abdominal surgery. Design, Setting, and Participants: This retrospective cohort study used CT imaging and electronic health record data from a random sample of adults who underwent abdominal surgery at 20 medical centers within Kaiser Permanente Northern California from January 1, 2010, to December 31, 2020. Data were analyzed from April 1, 2022, to December 1, 2023. Exposure: Body composition derived from automated analysis of multislice abdominal CT scans. Main Outcomes and Measures: The primary outcome of the study was all-cause 30-day postdischarge readmission or postoperative mortality. The secondary outcome was 30-day postoperative morbidity among patients undergoing abdominal surgery who were sampled for reporting to the National Surgical Quality Improvement Program. Results: The study included 48 444 adults; mean [SD] age at surgery was 61 (17) years, and 51% were female. Using principal component analysis, 3 body composition scores were derived: body size, muscle quantity and quality, and distribution of adiposity. Higher muscle quantity and quality scores were inversely correlated (r = -0.42; 95% CI, -0.43 to -0.41) with the HFRS and associated with a reduced risk of 30-day readmission or mortality (quartile 4 vs quartile 1: relative risk, 0.61; 95% CI, 0.56-0.67) and 30-day postoperative morbidity (quartile 4 vs quartile 1: relative risk, 0.59; 95% CI, 0.52-0.67), independent of sex, age, comorbidities, body mass index, procedure characteristics, and the HFRS. In contrast to the muscle score, scores for body size and greater subcutaneous and intermuscular vs visceral adiposity had inconsistent associations with postsurgical outcomes and were attenuated and only associated with 30-day postoperative morbidity after adjustment for the HFRS. Conclusions and Relevance: In this study, higher muscle quantity and quality scores were correlated with frailty and associated with 30-day readmission and postoperative mortality and morbidity, whereas body size and adipose tissue distribution scores were not correlated with patient frailty and had inconsistent associations with surgical outcomes. The findings suggest that assessment of muscle quantity and quality on CT can provide an objective measure of patient frailty that would not otherwise be clinically apparent and that may complement existing risk stratification tools to identify patients at high risk of mortality, morbidity, and readmission.
