Interpersonal supports for basic psychological needs and their relations with motivation, well-being, and performance: A meta-analysis.

People's motivational processes, well-being, and performance are likely to be facilitated through the support of others. Self-determination theory argues that interpersonal supports for autonomy, competence, and relatedness are crucial to achieve these outcomes. In the present study, we provide a comprehensive examination of this formulation based on a meta-analytic database consisting of 4,561 effect sizes from 881 independent samples (N = 443,556). Our results indicate that supports for autonomy, competence, and relatedness were strongly positively related with the satisfaction of these basic needs and strongly negatively related to their frustration. Interpersonal supports for basic needs were strongly positively related with subjective well-being and exhibited small to moderate positive associations with performance. Moderation analyses showed general stability of effects across cultures, although correlations of autonomy support to autonomous motivation weakened as a function of individualism. The opposite pattern was observed for the correlation between relatedness support and intrinsic motivation. Some effects also declined as a function of sample age and lag in measurements. We also find that competence- and relatedness-supportive behaviors explained incremental variance in basic need satisfaction even after controlling for the more established effects of autonomy support. In addition, lateral need supports explained incremental variance in basic need satisfaction after controlling for vertical sources of support. In sum, our results are consistent with the premise that to support optimal motivation, well-being, and performance, a broad set of behaviors that nurture all three basic needs, together with different sources of interpersonal support, should be considered to yield the most benefit.

Same-Day Discharge is Safe, Feasible Following Vaginal Hysterectomy with Apical Suspension.

Purpose: Studies involving minimally invasive hysterectomy and robotic sacrocolpopexy have demonstrated safety and feasibility of same-day discharge. There are limited data, however, on same-day discharge outcomes for vaginal hysterectomy and pelvic reconstruction. This study aimed to compare 30 and 90-day surgical outcomes between same-day discharge versus overnight stay following vaginal hysterectomy and apical suspension. Patients and Methods: This retrospective study evaluated surgeries performed over two time periods. Overnight stay was standard between December 2018 and February 2020. Same-day discharge was standard from December 2020 to February 2022. All patients who underwent vaginal hysterectomy with apical suspension were included. The primary outcome was to determine if there was an increase in 30-day readmission rates. Secondary outcomes included emergency department visits and reoperations within 30 days, the previous variables at 90 days, and the rate for successful same-day discharge. Results: A total of 324 patients were analyzed over the 30 months: 149 (46%) in the overnight stay group and 175 (54%) in the same-day discharge group. At 30 days, no difference was found between groups for readmissions (2.7% vs 4.0%, p = 0.56), emergency department visits (14.8% vs 14.9%, p = 1.0), or reoperations (2.0% vs.1.7%, p = 1.0). At 90 days, outcomes were also similar. Same-day discharge as standard practice was successful in 80% of patients. Conclusion: In this retrospective two cohort study, the safety of same-day discharge following vaginal hysterectomy with apical suspension was demonstrated with no increased risk of 30 or 90-day readmissions, emergency visits, or reoperation rates. The majority (80%) of patients were discharged on the day of surgery, suggesting feasibility of this model.

Late-Onset Sepsis Evaluation and Empiric Therapy in Extremely Low Gestational Age Newborns.

BACKGROUND: Little is known about late-onset sepsis (LOS) evaluations in extremely low gestational age newborns (ELGANs). We describe frequencies of LOS evaluation in ELGANs, infant characteristics, and empiric therapy choices during evaluations. METHODS: Cohort study of infants 22-28 weeks gestational age (GA) discharged from 243 centers from 2009 to 2018, excluding infants with congenital anomalies, discharged or deceased prior to postnatal day (PND) 2, or admitted after PND 2. A new LOS evaluation was defined as the first blood culture obtained between PND 3 and 90, or one obtained ≥1 day following a negative culture and ≥10 days from prior positive cultures. We determined numbers of evaluations and percentage positive by GA, center, and over time. We described characteristics associated with positive evaluations, infants with LOS, and empiric antimicrobials. We calculated descriptive and comparative statistics using Wilcoxon rank sum, Fisher's exact, or Pearson chi-square tests, as appropriate. RESULTS: Of 47,187 included infants, 67% had ≥1 LOS evaluation and 21% of evaluated infants had ≥1 LOS (culture positive) episode; 1.6 evaluations occurred per infant and 10% were positive. The percentage of infants evaluated and positive for LOS was higher at earlier GA. LOS was associated with inotrope support (15% vs. 9%; p < .001) and invasive mechanical ventilation (66% vs. 51%; p < .001). Infants with positive cultures were more likely than infants with negative cultures to receive empiric antimicrobials during the LOS evaluation (95% vs. 73%; p < .001). CONCLUSIONS: Among ELGANs, earlier GA and postnatal age were associated with LOS evaluation and positive cultures. Most infants undergoing evaluation were started on empiric antimicrobials.

Patient experiences following prolapse surgery implementing a same-day discharge model: a prospective study.

INTRODUCTION AND HYPOTHESIS: Previous research has not evaluated patient experiences following vaginal reconstructive surgery using a same-day discharge model. The objective of this study was to describe patient experiences following major vaginal reconstructive surgery and same-day discharge. METHODS: In this descriptive study, patients undergoing vaginal hysterectomy with pelvic reconstruction were preoperatively enrolled. Questionnaires detailing experience with same-day discharge, surgical recovery, and advice for prospective patients were completed. Our primary outcome was question 7 of the Surgical Satisfaction Questionnaire: Looking back, if you "had to do it all over again" would you have the surgery again? Descriptive statistics were performed, and correlations were performed with Spearman's rank test. RESULTS: Sixty patients were enrolled; 54 underwent surgery. Eighty-seven percent of patients completed the 12-week questionnaire. At 12 weeks, 96% of patients (n = 45) would have the surgery again, and 91% (n = 42) were satisfied with the results of surgery. Twelve weeks postoperatively, the most common patient-reported complications were urinary tract infection (n = 8, 17%), catheter concerns (n = 5, 11%), and constipation (n = 5, 11%). When asked to list the best parts of their surgical experience, half of patients felt that this was the office staff or physician themselves (n = 24, 51%). When asked what advice they would provide to future patients, the most common responses included having a support person at home and taking time for recovery. CONCLUSIONS: In this sample of women receiving same-day discharge following vaginal hysterectomy with pelvic reconstruction, we present a unique insight into the most common patient concerns postoperatively. Rates of satisfaction and comfort were high.

Rare Case of Chronic Unreduced Shoulder Dislocation: A Case Report and Literature Review.

Introduction: Chronic unreduced shoulder dislocations (CUSDs) are rare with a prevalence of 0.10-0.18%, usually occurring after car crashes, falls, assaults, getting out of bed, and seizures. Management is often open reduction and fixation. Most cases have been reported in countries with inadequate resources and access to care often leading to misdiagnosis and poor management. We report a case of a patient with a CUSD presenting to a chiropractor within a federally qualified health center (FQHC). Case Report: A 55-year-old, Spanish-speaking, uninsured, female was referred from her primary care provider to a chiropractor within a FQHC with right shoulder pain and reduced range of motion. The patient reported two incidences of right shoulder dislocation, the first being a closed reduction 1 year before presentation and the second occurring 5 months before presentation without any management. Radiographs demonstrated an unreduced right anterior shoulder dislocation. The patient was referred to an orthopedist who treats patients on a sliding scale according to their income. Conclusion: Because the patient was uninsured and did not have the necessary financial resources, she was unable to receive a shoulder reduction. These barriers often contribute to the misdiagnosis and increase morbidity associated with this pathology. Exercise therapy was not advised out of concern for further structural damage and neurovascular compromise. The recommended management is with topical pain creams and corticosteroid injections as directed by their primary care. Clinicians working with this population should be aware of the diagnosis, both typical and urgent features, complications, and the standard of care in this condition.

The human RAP1 and GFAPɛ proteins increase γ-secretase activity in a yeast model system.

Alzheimer's disease (AD) is an age-related disorder that results in progressive cognitive impairment and memory loss. Deposition of amyloid ß (Aß) peptides in senile plaques is a hallmark of AD. γ-secretase produces Aß peptides, mostly as the soluble Aß40 with fewer insoluble Aß42 peptides. Rare, early-onset AD (EOAD) occurs in individuals under 60 years of age. Most EOAD cases are due to unknown genetic causes, but a subset is due to mutations in the genes encoding the amyloid precursor protein that is processed into Aß peptides or the presenilins (PS1 and PS2) that process APP. PS1 interacts with the epsilon isoform of glial fibrillary acidic protein (GFAPɛ), a protein found in the subventricular zone of the brain. We have found that GFAPɛ interacts with the telomere protection factor RAP1 (TERF2IP). RAP1 can also interact with PS1 alone or with GFAPɛ in vitro. Our data show that the nuclear protein RAP1 has an extratelomeric role in the cytoplasm through its interactions with GFAPɛ and PS1. GFAPɛ coprecipitated with RAP1 from human cell extracts. RAP1, GFAPɛ, and PS1 all colocalized in human SH-SY5Y cells. Using a genetic model of the γ-secretase complex in Saccharomyces cerevisiae, RAP1 increased γ-secretase activity, and this was potentiated by GFAPɛ. Our studies are the first to connect RAP1 with an age-related disorder.

Patient Outcomes from Multidisciplinary Chronic Pain Programs in Safety Net Clinics: A Scoping Review.

Patients within the safety net, defined as gap healthcare services for un- or under-insured persons, disproportionately suffer high impact chronic pain. The purpose of this review was to examine pain-related outcomes from multidisciplinary programs for patients with chronic pain within the safety net. A scoping review was conducted based on the Arksey and O'Malley framework coupled with the Preferred Reporting Items for Systematic reviews and Meta-Analyses-Scoping Review checklist. CINAHL, MEDLINE, PubMed, and Google Scholar were searched for eligible articles published between January 1, 2010, and December 31, 2020. Grey literature was searched by typing relevant keywords into Google. Quantitative and qualitative outcomes were included. Data collected were charted and analyzed. Ten articles were included, with five demonstrating primarily quantitative results, three demonstrating primarily qualitative results, and the remaining two demonstrating primarily mixed results. Of the studies that utilized qualitative measures, themes included reduction in pain symptoms and the positive reception of a group-based pain management approach. Of the studies that employed quantitative measures, most demonstrated improvements in pain-related outcomes post-intervention, although not all statistically significant. Multidisciplinary pain programs may be of benefit to safety net patients with chronic pain. Further data collection is needed to determine the efficacy of these programs.

The Reduced Adaptability of H-Reflex Parameters to Postural Change With Deficiency of Foot Plantar Sensitivity.

Purpose: The project was to examine the influence of peripheral neuropathy (PN) severity on the relationship between Hoffmann-reflex (H-reflex) and postures. Methods: A total of 34 participants were recruited. H-reflex (H/M ratio and H-index) during prone, standing, and the heel-contact phase of walking was tested, along with foot sole sensitivity. Results: The participants were divided into three groups based on the severity of the foot sole sensitivity deficit: control, less (LA), and more (MA) affected with both feet 5.07 monofilament test scores ranging 10, 0-5, and 6-9, respectively. A significant group by the posture interaction was observed in the H/M ratio (F3.0, 41.9 = 2.904, p = 0.046, η p 2 = 0.172). In the control group, the H/M ratio of prone (22 ± 7%) was greater than that of the standing (13 ± 3%, p = 0.013) and heel-contact phase (10 ± 2%, p = 0.004). In the MA group, the H/M ratio of standing (13 ± 3%) was greater than that of the heel-contact phase (8 ± 2%, p = 0.011). The H-index was significantly different among groups (F2,28 = 5.711, p = 0.008, and η p 2 = 0.290). Post hoc analysis showed that the H-index of the control group (80.6 ± 11.3) was greater than that of the LA (69.8 ± 12.1, p = 0.021) and MA groups (62.0 ± 10.6, p = 0.003). Conclusion: In a non-PN population, the plantar sensory input plays an important role in maintaining standing postural control, while as for the PN population with foot sole sensitivity deficiency, type Ⅰ afferent fibers reflex loop (H-reflex) contributes more to the standing postural control. The H-index parameter is an excellent method to recognize the people with and without PN but not to distinguish the severity of PN with impaired foot sole sensitivity.

Hoffmann Reflex Measured From Lateral Gastrocnemius Is More Reliable Than From Soleus Among Elderly With Peripheral Neuropathy.

Introduction: Peripheral neuropathy (PN) affects up to 20% of the population over the age of 60. Hoffmann reflex (H-reflex) may assess PN adaptation by measuring the function of the peripheral neural system and central nervous system (CNS) modulation. This project aimed to find a reliable muscle among triceps surae muscles during standing and walking among the PN population. Materials and Methods: Sixteen older adults (> 65 years of age) diagnosed with PN were recruited in this study. The H-reflex test was conducted on the muscle belly of the soleus (SOL), the medial (MG), and lateral gastrocnemius (LG) during standing and walking (heel contact, midstance, and toe-off phases). All measurements were collected on two occasions, separated by at least 7 days. Intraclass correlation coefficients (ICCs) and their confidence intervals (CIs) were used to examine the consistency of the H-reflex outcome variables in the repeated tests for all three tested muscles. Results: The ICCs of H-index during standing and the three walking phases were poor to moderate in SOL (0.486∼0.737) and MG (0.221∼0.768), and moderate to high in LG (0.713∼0.871). The ICCs of H/M ratio were poor to moderate in SOL (0.263∼0.702) and MG (0.220∼0.733), and high in LG (0.856∼0.958). Conclusion: The H-reflex of LG was more reliable than SOL and MG during standing and walking among older adults with peripheral neuropathy. It is crucial for future studies in this population to study H-reflex of LG, not SOL and MG, for more reliable results.

The effect of loss of foot sole sensitivity on H-reflex of triceps surae muscles and functional gait.

Objective: To investigate the effects of foot sole insensitivity on the outcomes of the triceps surae muscle H-reflex and functional gait. Material and Methods: People with peripheral neuropathy were recruited and divided into two groups: people with more (n = 13, 73.3 ± 4.3 years old) or less (n = 10, 73.5 ± 5.3) sensitive tactile sensation. Their monofilament testing scores were 9.0 ± 1.5 (range: 7-10) and 2.3 ± 2.4 (range: 0-6) out of 10, respectively. H-reflex of the triceps surae muscles during quiet standing and their relationship with functional gait, 6 min walking distance (6MWD), and timed-up-and-go duration (TUG), were compared between groups. Results: No significant difference was detected for H-reflex parameters between the groups. The less sensitive group showed reduced (p < .05) functional gait capacity compared to the other group, 38.4 ± 52.7 vs. 463.5 ± 47.6 m for 6MWD, and 9.0 ± 1.5 vs. 7.2 ± 1.1s for TUG, respectively. A significant correlation (p < .05), worse functional gait related to greater H/M ratio, was observed in the less sensitive group, not the other group. Conclusion: Although there was no significant H-reflex difference between the groups, more pronounced tactile sensation degeneration affected functional gaits and their relationship with H-reflex.

The Impact of Hoffmann Reflex on Standing Postural Control Complexity in the Elderly with Impaired Plantar Sensation.

In people with peripheral neuropathy (PN), impaired plantar sensation can cause adaptive changes in the central nervous system (CNS), resulting in changes in the standing postural control, which is reflected in the variability of standing output signals. Standard deviation (SD) and entropy are reliable indicators of system variability, especially since entropy is highly sensitive to diseased populations. The relation between SD and entropy, CNS and center of pressure (COP) variability is unclear for people with severe PN. The purpose of this study was to explore the adaptability of the CNS to the severe of PN and its effect on the degree and complexity of COP variability. Here, people with PN were divided into less affected (LA) and more affected (MA) groups based on plantar pressure sensitivity. We studied Hoffmann reflex (H-reflex) and standing balance performance with the control group (n = 8), LA group (n = 10), and MA group (n = 9), recording a 30 s COP time series (30,000 samples) of double-leg standing with eyes open. We observed that the more affected group had less COP complexity than people without PN. There is a significant negative correlation between the SD and sample entropy in people without PN, less affected and more affected. The COP complexity in people without PN was inversely correlated with H-reflex. We concluded that: (1) The complexity of COP variability in patients with severe plantar sensory impairment is changed, which will not affect the degree of COP variability; (2) The independence of the COP entropy in the AP and ML directions decreased, and the interdependence increased in people with PN; (3) Although the CNS of people with PN has a greater contribution to standing balance, its modulation of standing postural control is decreased.

Perioperative, postoperative and anatomical outcomes of robotic sacrocolpopexy.

The study aimed to analyse the anatomical, perioperative and postoperative outcomes of the robotic-assisted sacrocolpopexy (RSCP). After obtaining Institutional Review Board (IRB #19-0167) approval, our retrospective case series included 144 consecutive patients that underwent an RSCP for symptomatic stage II pelvic organ prolapse (POP) or symptomatic/asymptomatic stage III/IV POP. Patient information included operative parameters, perioperative and postoperative complications, readmissions and reoperation. Demographics and baseline characteristics were summarised by frequencies and percentages for categorical variables, and by mean/median, standard deviation, and ranges for continuous variables. In our study, concomitant surgeries with sacrocolpopexy consisted of hysterectomy, Burch colposuspension and midurethral sling. The anatomical success rate was 87.5% and the reoperation rate was 10.4%. The mean follow-up time was 12.5 (±8.7) months. Intraoperative complications 13 (9%) were bowel serosal abrasion, bladder wall injuries, trochar site bleeds, subcutaneous emphysema and a retroperitoneal haematoma. Our results suggest that RSCP is a feasible and safe approach for the treatment of POP with a low complication rate and favourable medium-term outcomes regarding anatomical and symptomatic results.Impact statementWhat is already known on this subject? Pelvic organ prolapse affects more than 25% of women in the United States. Apical and anterior compartment defects are challenging cases and sacrocolpopexy is considered the gold standard treatment option for apical and anterior compartment defects. As technology has advanced, minimally invasive approaches have been popular with their pros.What the results of this study add? We present the highest volume case series in the literature from our tertiary care centre for robotic-assisted sacrocolpopexy (RSCP). Our results suggest that RSCP is a feasible and safe approach for the treatment of POP with a low complication rate and favourable 1-year outcomes regarding anatomical and subjective results.What the implications are of these findings for clinical practice and/or further research? Robotic-assisted sacrocolpopexy has the potential to gain more popularity in the near future based on accumulating data on its feasibility and safety results.

Targeting Dopamine Receptor D2 by Imipridone Suppresses Uterine Serous Cancer Malignant Phenotype.

Uterine serous cancer (USC) is an aggressive subtype of endometrial cancer, with poor survival and high recurrence rates. The development of novel and effective therapies specific to USC would aid in its management. However, few studies have focused solely on this rare subtype. The current study demonstrated that the orally bioavailable, investigational new drug and novel imipridone ONC206 suppressed USC cell proliferation and induced apoptosis both in vitro and in vivo. Disruption of the DRD2-mediated p38MAPK/ERK/PGC-1α network by ONC206 led to metabolic reprogramming and suppression of both glycolysis and oxidative phosphorylation. ONC206 also synergized with paclitaxel in reducing USC cell viability. In addition, DRD2 overexpression correlated with poor overall survival in patients. This study provides the first evidence that ONC206 induced metabolic reprogramming in USC cells and is a promising therapeutic agent for USC treatment. These findings support further development of ONC206 as a promising therapeutic agent and improves survival rates in patients with USC.

Knowledge of psychosocial factors associated with low back pain amongst health science students: a scoping review.

Background: Low back pain is a burden worldwide and biological, psychological, and social mechanisms play a role in its development and persistence. Current guidelines support care using the biopsychosocial model. However, biomedical constructs dominate clinician training, and it is unknown the extent to which health science students understand the psychosocial determinates of a patient's low back pain. Therefore, the aim of this scoping review is to report health science students' current knowledge of psychosocial factors associated with low back pain. Methods: A scoping review framework was used to search electronic databases for research examining health science students' knowledge of psychosocial factors associated with low back pain. The nature and findings of the studies are highlighted using the data charting tool. Each study was analyzed to determine the type of outcome measurement used. Scores were compared to minimum accepted scores, between disciplines, as education advanced, and after educational modules. Results: Fourteen studies published between 2004 and 2019 were identified. Seven healthcare disciplines were represented.In total, 12 different measurement tools were utilized. In 9 studies students demonstrated inadequate knowledge of psychosocial factors associated with low back pain. Three tools compared disciplines and nationalities. Three tools were associated with practice behavior. Eight studies showed improvement as students' education advanced, and 3 studies demonstrated improvements in knowledge after implementation of pain education modules of varied lengths. Of those, two showed significant improvement. Conclusions: Health science students in these studies had substandard understanding of psychosocial factors associated with low back pain. Dedicated pain education has the potential to improve low back pain understanding, resulting in more guideline appropriate care recommendation.

Differentiating Bilateral Symptomatic Hand Osteoarthritis From Rheumatoid Arthritis Using Sonography When Clinical and Radiographic Features Are Nonspecific: A Case Report.

OBJECTIVE: The purpose of this report is to describe a patient with bilateral symptomatic hand osteoarthritis (OA) originally thought to be rheumatoid arthritis (RA) based on clinical and radiographic features. CLINICAL FEATURES: A 48-year-old woman presented with bilateral hand pain, stiffness, swelling, and redness in the proximal and distal interphalangeal joints of 1 year's duration. Laboratory analysis and plain film radiography were equivocal. These findings necessitated the use of diagnostic ultrasound, which revealed no synovitis or erosions in the joints of the hand, so a diagnosis of bilateral symptomatic hand OA was rendered. INTERVENTION AND OUTCOME: A trial of conservative care consisting of mobilizations, instrument-assisted soft tissue therapy, and laser therapy was given. At 1-month follow-up, the patient regained full pain-free range of motion and strength and returned to complete work activity. CONCLUSION: This case report demonstrated that hand OA can present with nonspecific inflammatory-like clinical features. These findings require further testing, in which case ultrasound imaging may be valuable to differentiate OA from RA. Using ultrasound to make this diagnosis may guide management, with rheumatology referral for RA and conservative care for OA.

Embryonal mitochondrial DNA: relationship to embryo quality and transfer outcomes.

PURPOSE: The aim was to study the association between embryonal mitochondrial DNA (mtDNA) content and embryo quality and implantation outcomes. METHODS: A retrospective chart review was performed with data collected from a private IVF center database. The study population included female infertility patients with ages ranging from 31 to 38 years old, and the main outcome measures were embryo quality and transfer outcomes. RESULTS: From a total of 1510 blastocyst biopsies, the majority of embryos consisted of grade 1 (High), followed by grade 2 (mid), and grade 3 (poor). Embryos with higher mtDNA content were found to be of poorer quality (grade 3) relative to grades 1 and 2 (P = 0.003). Using a logistic model, mtDNA best predicted lowest and highest grades, but not mid-grade embryos. There was no correlation between mtDNA content and the subjects' age (R2 = 0.0018). In an analysis of only euploid embryos (N = 717), there was no longer an association between mtDNA content and embryo quality (P = 0.834). There was no difference in mtDNA content between groups of embryos that did and did not implant (P = 0.53). There was also no association noted between mtDNA content and ongoing pregnancy. Compared to day 6, day 5 blastocysts contain significantly higher amounts of mtDNA (P = 0.0005), lower rates of aneuploidy (P < 0.001), and were more likely to be high-quality blastocysts (grade 1) (P < 0.001). CONCLUSION: Although the mtDNA content shows some association to the morphologic grade of an embryo, this association does not persist in an analysis of only euploid embryos. Mitochondrial DNA content also does not appear to be associated with implantation or ongoing pregnancy. Day 5 blastocysts have significantly higher mtDNA content compared to day 6 blastocysts.

Recommendations and Choices for BRCA Mutation Carriers at Risk for Ovarian Cancer: A Complicated Decision.

Current ovarian cancer screening guidelines in high-risk women vary according to different organizations. Risk reducing surgery remains the gold standard for definitive treatment in BRCA mutation carriers, but research advancements have created more short-term options for patients to consider. The decisions involved in how a woman manages her BRCA mutation status can cause a great deal of stress and worry due to the imperfect therapy options. The goal of this review was to critically analyze the screening recommendations and alternative options for high-risk ovarian cancer patients and evaluate how these discrepancies and choices affect a woman's management decisions.

Safety and Efficacy of Pegfilgrastim When Given Less Than 14 Days Before the Next Chemotherapy Cycle: Review of Every 14-Day Chemotherapy Regimen Containing 5-FU Continuous Infusion.

BACKGROUND: Pegfilgrastim should not be given <14 days from the next chemotherapy because of concerns for cytopenias. Some clinicians are prescribing pegfilgrastim to be given <14 days in patients receiving 5-fluorouracil continuous infusion (5-FUCI) regimens. OBJECTIVE: To determine the effectiveness and safety of pegfilgrastim administered <14 days from the next chemotherapy in patients receiving 5-FUCI administered >46 hours. METHODS: Single-institution retrospective cohort study of patients who received 5-FUCI administered >46 hours from June 2013 to December 2015. The unit of measurement was chemotherapy cycles. End points included the safety and efficacy of giving pegfilgrastim <14 days from the next chemotherapy (Pegfilgrastim-Less-Than-14-Days-Group) and comparing that to pegfilgrastim given ≥14 days (Pegfilgrastim-More-Than-14-Days-Group), filgrastim only (Filgrastim-Group), and no colony stimulating factors (No-CSF-Group). Generalized estimating equations (GEEs) were used to compare mean absolute neutrophil count (ANC) and white blood cell count (WBC). Poisson regression models with GEE were used to estimate relative risk (RR) for neutropenia. RESULTS: There were no incidences of neutropenia, febrile neutropenia (FN), or hospitalizations for FN with the Pegfilgrastim-Less-Than-14-Days-Group. There was also a high mean ANC of 9.9 (5.7) × 109/L. Mean ANC and WBC were statistically significantly less with the Filgrastim-Group, No-CSF-Group, and Pegfilgrastim-More-Than-14-Days-Group compared with the Pegfilgrastim-Less-Than-14-Days-Group. The Filgrastim-Group and the No-CSF-Group had a 32% (1.10-1.56, P = 0.002) and 8% (1.04-1.12, P < 0.001) increased risk of incidence of neutropenia, respectively, compared with the Pegfilgrastim-Less-Than-14-Days-Group. The risk of incidence of neutropenia was the same with the Pegfilgrastim-More-Than-14-Days-Group and Pegfilgrastim-Less-Than-14-Days-Group (0.95-1.04, P = 0.821). CONCLUSION: This study shows a promising possibility that administering pegfilgrastim <14 days from the next chemotherapy cycle could be a safe and effective practice. However, better controlled clinical trials are needed.
