RESUMEN

Romantic first impressions seem to linger, but why? Few studies have investigated how romantic desire during initial interactions predicts later relational outcomes (e.g., later romantic interest, contact attempts) using a design that can tease apart different possible mechanisms (e.g., mate value, selectivity, compatibility). Across three speed-dating studies (n = 559) with longitudinal follow-ups (including college and community samples, and a sample of men who date men), we investigated whether different components of initial romantic impressions predicted later romantic outcomes and relationship initiation. Using the social relations model, we partitioned initial desire at speed dating (determined from 6,600+ total dates) into partner effects (a date's consensual desirability, e.g., mate value), actor effects (a participant's general desirousness, e.g., selectivity), and relationship effects (a participant's unique liking for a date over and beyond partner and actor effects, e.g., compatibility) to predict later evaluations (romantic interest, physical attraction, and desire to know better) and behaviors (direct messaging and going on dates). Meta-analyses across the three studies showed that, across 6,100+ follow-up reports, partner and relationship effects were especially strong predictors of relationship initiation variables. Consistent with evolutionary models of human pair bonding, these findings suggest that both consensually desirable traits and unique impressions of compatibility have lingering effects on relationship development, even from the moment that two potential partners meet.

RESUMEN

Schwann cells are critical for the proper development and function of the peripheral nervous system (PNS), where they form a collaborative relationship with axons. Past studies highlighted that a pair of proteins called the prohibitins play major roles in Schwann cell biology. Prohibitins are ubiquitously expressed and versatile proteins. We have previously shown that while prohibitins play a crucial role in Schwann cell mitochondria for long-term myelin maintenance and axon health, they may also be present at the Schwann cell-axon interface during development. Here, we expand on this, showing that drug-mediated modulation of prohibitins in vitro disrupts myelination and confirming that Schwann cell-specific ablation of prohibitin 2 (Phb2) in vivo results in severe defects in radial sorting and myelination. We show in vivo that Phb2-null Schwann cells cannot effectively proliferate and the transcription factors EGR2 (KROX20), POU3F1 (OCT6), and POU3F2 (BRN2), necessary for proper Schwann cell maturation, are dysregulated. Schwann cell-specific deletion of Jun, a transcription factor associated with negative regulation of myelination, confers partial rescue of the developmental defect seen in mice lacking Schwann cell Phb2. Finally, we identify a pool of candidate PHB2 interactors that change their interaction with PHB2 depending on neuronal signals, and thus are potential mediators of PHB2-associated developmental defects. This work develops our understanding of Schwann cell biology, revealing that Phb2 may modulate the timely expression of transcription factors necessary for proper PNS development, and proposing candidates that may play a role in PHB2-mediated integration of axon signals in the Schwann cell.

RESUMEN

OBJECTIVE: The aim of this study was to compare infectious complications in pancreatoduodenectomy (PD) patients with biliary stents treated with short, medium, or long durations of prophylactic antibiotics. BACKGROUND: Pre-existing biliary stents have historically been associated with higher infection risk after PD. Patients are administered prophylactic antibiotics, but the optimal duration remains unknown. METHODS: This single-institution retrospective cohort study included consecutive PD patients from October 2016 to April 2022. Antibiotics were continued past the operative dose per surgeon discretion. Infection rates were compared by short (≤24 h), medium (>24 but ≤96 h), and long (>96 h) duration antibiotics. Multivariable regression analysis was performed to evaluate associations with a primary composite outcome of wound infection, organ-space infection, sepsis, or cholangitis. RESULTS: Among 542 PD patients, 310 patients (57%) had biliary stents. The composite outcome occurred in 28% (34/122) short, 25% (27/108) medium, and 29% (23/80) long-duration ( P =0.824) antibiotic patients. There were no differences in other infection rates or mortality. On multivariable analysis, antibiotic duration was not associated with infection rate. Only postoperative pancreatic fistula (odds ratio 33.1, P <0.001) and male sex (odds ratio 1.9, P =0.028) were associated with the composite outcome. CONCLUSIONS: Among 310 PD patients with biliary stents, long-duration prophylactic antibiotics were associated with similar composite infection rates to short and medium durations but were used almost twice as often in high-risk patients. These findings may represent an opportunity to de-escalate antibiotic coverage and promote risk-stratified antibiotic stewardship in stented patients by aligning antibiotic duration with risk-stratified pancreatectomy clinical pathways.

RESUMEN

OBJECTIVE: We aimed to determine if advances in neoadjuvant therapy affected recurrence patterns and survival outcomes after pancreatectomy for pancreatic ductal adenocarcinoma (PDAC). BACKGROUND: Data are limited on how modern multimodality therapy affects PDAC recurrence and post-recurrence survival. METHODS: Patients who received neoadjuvant therapy followed by curative-intent pancreatectomy for PDAC during 1998-2018 were identified. Treatments, recurrence sites and timing, and survival were compared between patients who completed neoadjuvant therapy and pancreatectomy in 1998-2004, 2005-2011, and 2012-2018. RESULTS: The study included 727 patients (203, 251, and 273 in the 1998-2004, 2005-2011, and 2012-2018 cohorts, respectively). Use of neoadjuvant induction chemotherapy increased over time, and regimens changed over time, with >80% of patients treated in 2012-2018 receiving FOLFIRINOX or gemcitabine with nab-paclitaxel. Overall, recurrence sites and incidence (67.5%, 66.1%, and 65.9%) remained stable, and 85% of recurrences occurred within 2 years of surgery. However, compared to earlier cohorts, the 2012-2018 cohort had lower conditional risk of recurrence in postoperative year 1 and higher risk in postoperative year 2. Overall survival increased over time (median, 30.6, 33.6, and 48.7 mo, P < 0.005), driven by improved post-recurrence overall survival (median, 7.8, 12.5, and 12.6 mo; 3-year rate, 7%, 10%, and 20%; P < 0.005). CONCLUSIONS: We observed changes in neoadjuvant therapy regimens over time and an associated shift in the conditional risk of recurrence from postoperative year 1 to postoperative year 2, although recurrence remained common. Overall survival and post-recurrence survival remarkably improved over time, reflecting improved multimodality regimens for recurrent disease.

RESUMEN

BACKGROUND: Robotic pancreatoduodenectomy is an increasingly accepted alternative for the treatment of pancreatic ductal adenocarcinoma (PDAC).1 However, the ability to perform a meticulous robotic-assisted superior mesenteric artery (SMA) dissection to obtain a margin-negative resection remains unknown.2 PDAC within the head of the pancreas (HOP) that involves the superior mesenteric vein (SMV) and portal vein (PV) requires total venous control (TVC) and a 'vein-to-the-right' (or anterior artery-first) approach to SMA dissection to minimize venous congestion and operative blood loss.3-5 Here, we demonstrate a robotic pancreatoduodenectomy with TVC and a 'vein-to-the-right' approach. METHODS: A 70-year-old woman with cT2N0M0 HOP PDAC with lateral SMV involvement and right gastroepiploic vein occlusion underwent robotic pancreatoduodenectomy after neoadjuvant chemotherapy. After transecting the pancreas, we achieved TVC by dividing the small venous tributaries and encircling the SMV, splenic vein, and PV. We then proceeded with a 'vein-to-the-right' approach. The inferior pancreatoduodenal arteries were divided to minimize HOP inflow and decrease specimen bleeding. Once the specimen was dissected off the periadventitial plane of the distal SMA, the SMV dissection was carefully performed using a partial side-wall vein resection using a vascular stapler. RESULTS: Total operative time was 7.5 h and estimated blood loss was 25 mL. The patient recovered well postoperatively and was discharged on postoperative day 3. Final pathology exhibited a 2.4 cm, moderately to poorly differentiated adenocarcinoma with negative margins (ypT2N1, 2/38 lymph nodes positive). CONCLUSION: For tumors with lateral vein involvement, robotic pancreatoduodenectomy can be safely performed via TVC and a 'vein-to-the-right' approach.

RESUMEN

BACKGROUND: There are very few mechanistic studies of the long-term impact of psychosocial interventions in childhood. The parent-mediated Paediatric Autism Communication Therapy (PACT) RCT showed sustained effects on autistic child outcomes from pre-school to mid-childhood. We investigated the mechanism by which the PACT intervention achieved these effects. METHODS: Of 152 children randomised to receive PACT or treatment as usual between 2 and 5 years of age, 121 (79.6%) were followed 5-6 years after the endpoint at a mean age of 10.5 years. Assessors, blind to the intervention group, measured Autism Diagnostic Observation Scale Calibrated Severity Score (ADOS CSS) for child autistic behaviours and Teacher Vineland (TVABS) for adaptive behaviour in school. Hypothesised mediators were child communication initiations with caregivers in a standard play observation (Dyadic Communication Measure for Autism, DCMA). Hypothesised moderators of mediation were baseline child non-verbal age equivalent scores (AE), communication and symbolic development (CSBS) and 'insistence on sameness' (IS). Structural equation modelling was used in a repeated measures mediation design. RESULTS: Good model fits were obtained. The treatment effect on child dyadic initiation with the caregiver was sustained through the follow-up period. Increased child initiation at treatment midpoint mediated the majority (73%) of the treatment effect on follow-up ADOS CSS. A combination of partial mediation from midpoint child initiations and the direct effect of treatment also contributed to a near-significant total effect on follow-up TVABS. No moderation of this mediation was found for AE, CSBS or IS. CONCLUSIONS: Early sustained increase in an autistic child's communication initiation with their caregiver is largely responsible for the long-term effects from PACT therapy on autistic and adaptive behaviour outcomes. This supports the theoretical logic model of PACT therapy but also illuminates fundamental causal processes of social and adaptive development in autism over time: early social engagement in autism can be improved and this can have long-term generalised outcome effects.

RESUMEN

INTRODUCTION: Suturing is an expected skill for students graduating from health professions programs. Previous studies investigated student experience with teaching sessions utilizing constructive feedback versus compliments but did not investigate the combination of both. METHODS: In this parallel, randomized controlled trial, participants were divided into three groups: feedback (F), compliments (C), or feedback and compliments (FC). Participants received standardized instruction on simple interrupted suturing and two-handed knot-tying, and were videotaped performing this skill before and after the intervention. Performance was evaluated using a validated Objective Structured Assessment of Technical Skills (OSATS) instrument. Participants completed a preintervention and postintervention survey rating their task enjoyment and self-assessment of performance. Analysis was performed to determine differences between and within the groups using Kruskal-Wallis, Wilcoxon rank-sum, and Mann-Whitney U tests. RESULTS: A total of 31 students participated: 11 in C, 10 in F, and 10 in FC. The groups had similar preintervention OSATS scores. The F and FC groups demonstrated significant improvement in OSATS score after intervention, group C was not significantly different: F median of 11.25-19.75 points (P = 0.002); FC median of 11.75-21 points (P = 0.002); C median of 13-14 points (P = 0.2266). Between the groups FC and F both had significant performance improvement compared with C (P < 0.001 and P = 0.001 respectively). The FC group had a significantly higher rating of their enjoyment of the task on the postintervention survey compared with both the C and F groups with a median rating of 10 compared with 8 and 8 (P = 0.0052 and P = 0.0126, respectively). CONCLUSIONS: The combination of feedback and compliments was associated with improvement in performance on suturing and knot-tying similar to the feedback-only group. The FC group rated a higher level of enjoyment of the activity compared to feedback or compliments alone.

RESUMEN

BACKGROUND: Although robotic pancreatectomy may facilitate an earlier functional recovery, the impact of a robotic pancreatectomy program during its early experience on the timing of return to intended oncologic therapy (RIOT) after surgery is unknown. METHODS: In this retrospective cohort study, we used propensity score matching with a 1:2 ratio to compare patients who underwent robotic or open surgery (distal pancreatectomy or pancreatoduodenectomy) for pancreatic ductal adenocarcinoma (PDAC) during the first 3 years of our robotic pancreatectomy experience (January 2018-December 2021). Generalized estimating equations modeling was used to evaluate the effect of surgical approach on early RIOT, defined as adjuvant chemotherapy initiation within 8 weeks after surgery, and late RIOT, defined as initiation within 12 weeks after surgery. RESULTS: The matched cohort included 26 patients who underwent robotic pancreatectomy and 52 patients who underwent open pancreatectomy. Rates of receipt of adjuvant chemotherapy were 96.2% and 78.9%, respectively. Rate of early RIOT in the robotic group (73.1% was higher than that in the open group (44.2%; P = 0.018). In multivariable analysis, a robotic approach was associated with early RIOT (odds ratio, 3.54; 95% confidence interval 1.08-11.62; P = 0.038). Surgical approach did not impact late RIOT (odds ratio, 3.21; 95% confidence interval 0.71-14.38; P = 0.128). CONCLUSIONS: Compared with open pancreatectomy, robotic pancreatectomy did not delay RIOT. In fact, odds of early RIOT were increased, which supports the oncological safety of our robotic pancreatectomy program during its implementation.

RESUMEN

ABSTRACT: Neuroendocrine neoplasms (NENs) are rapidly evolving small bowel tumors, and the patients are asymptomatic at the initial stages. Metastases are commonly observed at the time of presentation and diagnosis. This review addresses the small bowel NEN (SB-NEN) and its molecular, histological, and imaging features, which aid diagnosis and therapy guidance. Somatic cell number alterations and epigenetic mutations are studied to be responsible for sporadic and familial SB-NEN. The review also describes the grading of SB-NEN in addition to rare histological findings such as mixed neuroendocrine-non-NENs. Anatomic and nuclear imaging with conventional computed tomography, magnetic resonance imaging, computed tomographic enterography, and positron emission tomography are adopted in clinical practice for diagnosing, staging, and follow-up of NEN. Along with the characteristic imaging features of SB-NEN, the therapeutic aspects of imaging, such as peptide receptor radionuclide therapy, are discussed in this review.

RESUMEN

OBJECTIVE: Malnutrition is an important risk factor for patient surgical outcomes. This is especially true for head and neck cancer (HNC) patients receiving a total laryngectomy with free flap reconstruction (TLwFFR). Preoperative prealbumin and albumin values have both been used to indicate poor nutrition. This study aims to identify the prognostic value of preoperative prealbumin and albumin levels with wound healing complications in HNC patients after TLwFFR. METHODS: A retrospective review was conducted in all HNC patients who underwent TLwFFR from 2016 to 2022 at a tertiary-care institution. Patients with either preoperative (within 1 month of surgery) prealbumin or albumin lab values were included. Low preoperative prealbumin (low prealbumin) levels and low preoperative albumin (low albumin) levels were defined as ≤20 mg/dL and <3.4 g/dL, respectively. Outcomes collected included all wound healing complications (infection, wound dehiscence, pharyngocutaneous fistula). The association between prealbumin and albumin with outcomes were analyzed using multivariable logistic regression. RESULTS: A total of 83 patients met the inclusion criteria. The mean age at surgery was 61.6 ± 9.3. The overall wound healing complication rate was 33.7 %. There was an association between low prealbumin levels and any wound healing complication. On multivariate analysis, low prealbumin levels were associated with postoperative wound healing complications (OR, 4.7; CI 1.3-17.0. P = 0.02) after controlling for low albumin level, age, smoking, and preoperative radiation. CONCLUSIONS: Low prealbumin levels were associated with wound healing complications in TLwFFR patients. Consideration of consistent prealbumin testing with nutritional intervention may reduce wound healing complications.

RESUMEN

OBJECTIVE: We sought to characterize differences in pancreatectomy recommendation rates to surgically eligible patients with pancreatic ductal adenocarcinoma of the pancreatic head across age and racial groups. BACKGROUND: Pancreatectomy is not recommended in almost half of otherwise healthy patients with stage I/II pancreatic ductal adenocarcinoma lacking a surgical contraindication. We characterized differences in pancreatectomy recommendation among surgically eligible patients across age and racial groups. METHODS: Non-Hispanic White (NHW) and Non-Hispanic Black (NHB) patients were identified in the National Cancer Database with clinical stage I/II pancreatic head adenocarcinoma, Charlson Comorbidity Index of 0 to 1, and age 40 to 89 years. Rates of surgery recommendation and overall survival (OS) by age and race were compared. A Pancreatectomy Recommendation Equivalence Point (PREP) was defined as the age at which the rate of not recommending surgery matched the rate of recommending and completing surgery. Marginal standardization was used to identify association of age and race with recommendation. OS was compared using Kaplan-Meier and Cox regression models. RESULTS: Among 40,866 patients, 36,133 (88%) were NHW and 4733 (12%) were NHB. For the entire cohort, PREP was 79 years. PREP was 5 years younger in NHB patients than in NHW patients (75 vs 80 years). Adjusted rates of not recommending surgery were significantly higher for NHB than for NHW patients in each age group. After adjusting for surgery recommendation, we found no difference in OS between NHW and NHB patients (hazard ratio 0.98 [95% CI 0.94-1.02]). CONCLUSIONS: PREP of NHB patients was 5 years younger than NHW patients, and in every age group, the rate of not recommending pancreatectomy was higher in NHB patients. Age and race disparities in treatment recommendations may contribute to shorter longevity of NHB patients.

RESUMEN

OBJECTIVE: Within a learning health system paradigm, this study sought to evaluate reasons for readmission to identify opportunities for improvement. SUMMARY BACKGROUND DATA: Post-pancreatectomy readmission rates have remained constant despite improved index hospitalization metrics. METHODS: We performed a single-institution case-control study of consecutive pancreatectomy patients (October 2016 - April 2022). Complications were prospectively graded in biweekly faculty and advanced practice provider meetings. We analyzed risk factors during index hospitalization and categorized indications for 90-day readmissions. RESULTS: A total of 835 patients, median age 65 years and 51% (427/835) males, underwent 64% (534/835) pancreatoduodenectomies, 34% (280/835) distal pancreatectomies, and 3% (21/835) other resections. 24% (204/835) of patients were readmitted. Primary indication for readmission was technical in 51% (105/204), infectious in 17% (35/204), and medical/metabolic in 31% (64/204) of patients. Procedures were required in 77% (81/105) and 60% (21/35) of technical and infectious readmissions, respectively, while 66% (42/64) of medical/metabolic readmissions were managed non-invasively. During the index hospitalization, benign pathology (OR 1.8, P=0.049), biochemical pancreatic leak (OR 2.3, P=0.001), bile/gastric/chyle leak (OR 6.4, P=0.001), organ-space infection (OR 3.4, P=0.007), undrained fluid on imaging (OR 2.4, P=0.045), and increasing white blood cell count (OR 1.7, P=0.045) were independently associated with odds of readmission. CONCLUSIONS: Most readmissions following pancreatectomy were technical in origin. Patients with complications during index hospitalization, increasing white blood cell count, or undrained fluid before discharge were at highest risk for readmission. Pre-discharge risk-stratification of readmission risk factors and augmentation of in-clinic resources may be strategies to reduce readmission rates.

RESUMEN

OBJECTIVE: To characterize associations between carbohydrate antigen 19-9 (CA19-9) dynamics during neoadjuvant therapy (NT) and survival for patients with pancreatic ductal adenocarcinoma (PDAC). BACKGROUND: Although normalization of CA19-9 during NT is associated with improved outcomes following PDAC resection, we hypothesize that CA19-9 dynamics during NT can improve prognostication. METHODS: Characteristics for patients with PDAC undergoing NT (July 2011-October 2018) with ≥3 CA19-9 results (bilirubin<2mg/dL) were collected and grouped by CA19-9 dynamics. Nonproducers (<1 U/ml) were excluded, and normal was ≤35 U/ml. Postresection survival was compared among groups. RESULTS: Of 431 patients, 166 had eligible CA19-9 values. Median baseline CA19-9 was 98 U/ml. Overall 2-year postresection recurrence-free survival (RFS) and overall survival (OS) were 37% and 63%, respectively. Patients with normalization (53%) had improved 2-year RFS (47% vs. 28%, P = 0.01) and OS (75% vs. 49%, P = 0.01). CA19-9 dynamics during NT were analyzed by shape, direction, and normalization creating response types ("A-B-C-D-E"). Type A was "Always" decreasing to normalization, B "Bidirectional" with eventual normalization, C "Consistently" normal, D any "Decrease" without normalization, and E "Elevating" without normalization. Types A and B responses were associated with the longest postresection 2-year RFS (51% and 56%) and OS (75% and 92%, respectively) whereas Types D and E had the worst outcomes. After adjusting for node-positivity, perineural invasion, and margin-positivity, CA19-9 response types were independently associated with both RFS and OS, and predicted outcomes are better than CA19-9 normalization alone (likelihood ratio test RFS P < 0.001, OS P = 0.01). CONCLUSIONS: This novel A-B-C-D-E classification of CA19-9 dynamics during NT was associated with postresection outcomes more precisely than CA19-9 normalization alone.

RESUMEN

BACKGROUND: Regional lymph node metastasis (RLNM) occurs infrequently in patients with soft tissue sarcoma (STS), although certain STS subtypes have a higher propensity for RLNM. The identification of RLNM has significant implications for staging and prognosis; however, the precise impact of node-positive disease on patient survival remains a topic of controversy. Although the benefits of sentinel lymph node biopsy (SLNB) are well documented in patients with melanoma and breast cancer, whether this procedure offers a benefit in STS is controversial. METHODS: A systematic literature search was performed and articles reviewed to determine if SLNB in patients with extremity/truncal STS impacts disease-free or overall survival. RESULTS: Six studies were included. Rates of sentinel lymph node positivity were heterogeneous (range 4.3-50%). The impact of SLNB on patient outcomes remains unclear. The overall quality of available evidence was low, as assessed by the Grading of Recommendations, Assessment, Development, and Evaluation system. CONCLUSIONS: The literature addressing the impact of nodal basin evaluation on the staging and management of patients with extremity/truncal STS is confounded by heterogeneous patient cohorts and clinical practices. Multicenter prospective studies are warranted to determine the true incidence of RLNM and whether SLNB could benefit patients with clinically occult RLNM at diagnosis.

RESUMEN

Oncoplastic surgery (OPS) is a form of breast conservation that combines definitive oncologic resection with optimal aesthetic outcomes. Various definitions exist, with most focusing on volume displacement techniques to close the lumpectomy defect and redistribute the remaining breast volume over the preserved breast. Although its oncologic safety has been well demonstrated, uptake into practice varies globally. This article details the definition, safety, training opportunities, and practice patterns of OPS on a global scale.

RESUMEN

Gender differences in appraisals of first intercourse are among the largest in sexuality research, with women indicating less satisfying "sexual debuts" than men. Dispositional or "actor-level" explanations for this gender gap are pervasive, yet research has largely examined heterosexual debuts in which actor gender and partner gender are confounded. We assessed whether women's less satisfying sexual debuts are better explained by actor gender or partner gender, comparing experiences of women who debuted with men (WDM) with those of men and women who debuted with women (MDW, WDW). Retrospective accounts of sexual debut were collected from 3033 adults. At first intercourse, we found that WDW had equal physical and emotional satisfaction to MDW, and more satisfaction than WDM, suggesting satisfaction gaps owing to partner gender, not actor gender. This pattern did not extend to a comparison event (first masturbation), where WDW and WDM had similar satisfaction, but less satisfaction than MDW, suggesting an actor gender gap. To identify sources of satisfaction gaps, we probed for corresponding differences in the circumstances of sexual debut. Sexual circumstances were more strongly implicated than nonsexual ones, with relative deprivation of glans stimulation explaining relative dissatisfaction at first intercourse, but not first masturbation, and orgasm explaining it at both. Findings challenge the view that the satisfaction gap at first intercourse reflects an inherent difference between genders. Indeed, they demonstrate similarities when partner gender does not differ and suggest strategies for ensuring equal sexual satisfaction-and equal sexual rights realization-at (hetero) sexual debut.

RESUMEN

ABSTRACT: Neuroendocrine neoplasms have shown a linear increase in incidence and prevalence in recent decades, primarily due to improved cross-sectional imaging, expanded use of endoscopic procedures, and advanced genetic analysis. However, diagnosis of hereditary neuroendocrine tumors is still challenging because of heterogeneity in their presentation, the variety of tumor locations, and multiple associated syndromes. Radiologists should be familiar with the spectrum of these tumors and associated hereditary syndromes. Furthermore, as the assessment of multiple tumor elements such as morphology, biochemical markers, and presence of metastatic disease are essential for the treatment plan, conventional anatomic and functional imaging methods are fundamental in managing and surveilling these cases. Our article illustrates the role of different cross-sectional imaging modalities in diagnosing and managing various hereditary abdominopelvic neuroendocrine tumors.

RESUMEN

PURPOSE: To determine the efficacy and efficiency of laparoscopic transverse abdominis plane block (Lap-TAP) in patients undergoing pancreatoduodenectomy and gastrectomy compared to those of ultrasound-guided TAP (US-TAP). METHODS: We retrospectively analyzed the records of patients who underwent open or minimally invasive (MIS) pancreatoduodenectomy and major gastrectomy with the use of Lap-TAP or US-TAP at our institution between November 1, 2018, and September 30, 2021. We compared the estimated time and cost associated with Lap-TAP and US-TAP. We also compared postoperative opioid use and pain scores between patients who underwent open laparotomy with these TAPs. RESULTS: A total of 194 patients were included. Overall, 114 patients (59%) underwent pancreatectomy, and 80 patients (41%) underwent gastrectomy. Additionally, 138 patients (71%) underwent an open procedure, and 56 patients (29%) underwent MIS. A total of 102 patients (53%) underwent US-TAP, and 92 (47%) underwent Lap-TAP. The median time to skin incision was significantly shorter in the Lap-TAP group (US-TAP, 59 min vs. Lap-TAP, 45 min; P < 0.001), resulting in an estimated reduction in operation cost by $602. Pain scores and postoperative opioid use were similar between Lap-TAP and US-TAP among open surgery patients, indicating equivalent pain control between Lap-TAP and US-TAP. CONCLUSION: Lap-TAP was equally effective in pain control as US-TAP after pancreatectomy and gastrectomy, and Lap-TAP can reduce operation time and cost. Lap-TAP is considered the preferred approach for MIS pancreatectomy and gastrectomy, which occasionally needs conversion to laparotomy.

RESUMEN

Given the powerful implications of relationship quality for health and well-being, a central mission of relationship science is explaining why some romantic relationships thrive more than others. This large-scale project used machine learning (i.e., Random Forests) to 1) quantify the extent to which relationship quality is predictable and 2) identify which constructs reliably predict relationship quality. Across 43 dyadic longitudinal datasets from 29 laboratories, the top relationship-specific predictors of relationship quality were perceived-partner commitment, appreciation, sexual satisfaction, perceived-partner satisfaction, and conflict. The top individual-difference predictors were life satisfaction, negative affect, depression, attachment avoidance, and attachment anxiety. Overall, relationship-specific variables predicted up to 45% of variance at baseline, and up to 18% of variance at the end of each study. Individual differences also performed well (21% and 12%, respectively). Actor-reported variables (i.e., own relationship-specific and individual-difference variables) predicted two to four times more variance than partner-reported variables (i.e., the partner's ratings on those variables). Importantly, individual differences and partner reports had no predictive effects beyond actor-reported relationship-specific variables alone. These findings imply that the sum of all individual differences and partner experiences exert their influence on relationship quality via a person's own relationship-specific experiences, and effects due to moderation by individual differences and moderation by partner-reports may be quite small. Finally, relationship-quality change (i.e., increases or decreases in relationship quality over the course of a study) was largely unpredictable from any combination of self-report variables. This collective effort should guide future models of relationships.
