RESUMO

Chronic caloric restriction (CR) has powerful anticarcinogenic actions in both preclinical and clinical studies but may be difficult to sustain. As an alternative to CR, there has been growing interest in intermittent fasting (IF) in both the scientific and lay community as a result of promising study results, mainly in experimental animal models. According to a survey by the International Food Information Council Foundation, IF has become the most popular diet in the last year, and patients with cancer are seeking advice from oncologists about its beneficial effects for cancer prevention and treatment. However, as discussed in this review, results from IF studies in rodents are controversial and suggest potential detrimental effects in certain oncologic conditions. The effects of IF on human cancer incidence and prognosis remain unknown because of a lack of high-quality randomized clinical trials. Preliminary studies suggest that prolonged fasting in some patients who have cancer is safe and potentially capable of decreasing chemotherapy-related toxicity and tumor growth. However, because additional trials are needed to elucidate the risks and benefits of fasting for patients with cancer, the authors would not currently recommend patients undergoing active cancer treatment partake in IF outside the context of a clinical trial. IF may be considered in adults seeking cancer-prevention benefits through means of weight management, but whether IF itself affects cancer-related metabolic and molecular pathways remains unanswered.

RESUMO

Objectives: Nursing home (NH) residents' capacity to communicate deteriorates with dementia. Consequently, NHs with high proportions of people living with dementia (PLWD) may receive fewer resident complaints, and/or investigating complaints may be challenging. We assessed NHs' proportion of PLWD in relation to total and substantiated complaints. Methods: Data were from the ASPEN Complaints/Incident Tracking System and the Certification and Survey Provider Enhanced Reports (2017). NHs (N = 15,499) were categorized based on high (top-10%), medium (middle-80%), and low (bottom-10%) dementia prevalence. Negative binomial Poisson regression assessed complaint patterns in relation to NHs' high/low (vs. medium) proportions of PLWD and other facility/resident characteristics. Results: Compared to NHs with medium-dementia prevalence, NHs with low proportions of PLWD had higher total (average marginal effect [AME] = 0.16, p < 0.001) and substantiated (AME = 0.30, p < 0.001) complaints, whereas NHs with high proportions of PLWD had fewer total (AME= -0.07; p < 0.05) and substantiated (AME= -0.11, p < 0.05) complaints. Also, NHs' profit status, chain-affiliation, size, staffing, and resident ethnicity were associated with total and substantiated complaints. Conclusion: The association between high proportions of PLWD and lower NH complaints suggests either that these NHs have higher overall quality or that complaints are underreported. Regardless, surveyors and families may need more involvement in monitoring higher dementia prevalence facilities.

RESUMO

OBJECTIVES: Project VITAL At Home aimed to combat social isolation and loneliness in family caregivers of people with dementia through purposeful engagement and connection. This project examined the effects of technology on caregiver loneliness and well-being, as well as their technology experiences, during the COVID-19 pandemic. METHODS: Family caregivers were provided iN2L tablets and access to Alzheimer's Association supportive programs. Caregivers (n = 124) completed online surveys at pre and post evaluation points (average 7 months apart) to assess loneliness, subjective well-being (affect), supportive program usage, and tablet experiences. RESULTS: Family caregivers had positive perceptions of the tablets for both themselves and their family members. Tablets had positive effects on caregiver well-being, including giving them an additional caregiver tool, alleviating stress, increasing satisfaction with quiet time, and improving access to supportive programs. Caregiver positive affect decreased, but no changes were observed for negative affect or loneliness. CONCLUSIONS: Family caregivers found value in the tablets and showed improvements in some aspects of well-being. Randomized trials are needed to more fully assess the benefits of the intervention. CLINICAL IMPLICATIONS: Pairing tablets with caregiving supports is a promising intervention to improve caregivers' access to vital resources and services and to improve their well-being.

RESUMO

Complaints provide important information to consumers about nursing homes (NHs), but how substantiated complaints map onto deficiency citations is unknown. The purpose of this study is to understand the relationship between substantiated complaints and deficiency citations. Federally collected NH complaint and inspection records were obtained to identify all single allegation, substantiated complaints for NHs across the U.S. in 2017. Overall, the 369 complaint allegations in our sample resulted in a total of 585 deficiencies at the inspection stage; however, 35.2% of the allegations led to no deficiencies. Nearly two-thirds of the 369 substantiated single allegation complaints were categorized at the intake stage as quality of care (31.7%), resident abuse (17.3%), or resident neglect (14.1%). Further, 18% of the inspection deficiencies originated with complaint allegations that were prioritized as immediate jeopardy at intake, but of these, 71.4% were determined upon inspection to constitute "no actual harm with potential for more than minimal harm." These results provide evidence that complaints have the potential to provide unique valuable information on NH quality of care and draw regulatory attention to consumers' concerns. Future studies should include qualitative research concerning complaint processes by conducting interviews/surveys of complainants, NH staff/administrators, long-term care ombudsmen, and state officials.

RESUMO

Quality of care in assisted living communities (ALCs) is important to consumers. The coronavirus disease of 2019 (COVID-19) pandemic and associated emergency policies have posed major challenges on staff recruitment and retention. This study aimed to examine the relationship between organizational characteristics of ALCs in Florida and challenges with staff absence during COVID-19 (N = 129 ALCs). Results indicated that structures (provision of memory care services), processes of care (challenges hiring new staff, staff sent home to comply with precautions, and staff anxiety), and local COVID-19 positivity rate were significantly associated with staff absence due to fear of infection, sickness, or family responsibilities. ALC providers and state regulatory agencies should develop policies and procedures that take these issues into consideration to prepare for future emergencies and disasters. Infection control policies should reflect whether an ALC provides memory care services and inform ways to overcome potential challenges with protocols. Efforts to reduce staff anxiety and disaster-related concerns should also be considered to ensure quality of care during emergencies.


ALCs who provided memory care services had significantly greater challenges with staff absence due to fear of infection during the COVID-19 pandemic.The administrative action of sending staff home to comply with COVID-19 precautions, difficulty hiring new staff, and staff anxiety were process characteristics of ALCs associated with greater challenges with staff absence.Policymakers should consider whether an ALC provides memory care services, faces potential challenges with infection control protocols, and addresses the mental health of staff when creating and implementing infection control policies.

RESUMO

Face detection relies on the visual features that are shared across different faces. An important component of the basic spatial configuration of a face is symmetry around the vertical midline. Although human faces are structurally symmetrical, they can be asymmetrical in an image due to the direction of lighting or the position of the face. In the experiments presented here, we examined how face detection from simple contrast patterns that occur across the face is affected by the image asymmetries associated with variations in the horizontal lighting direction. We presented observers with two-tone images of faces (Mooney faces) that isolated the unique pattern of contrast in the shading and shadows on a face, illuminated from a wide range of horizontal directions. In two experiments, we found that face detection is surprisingly robust to these lighting changes, with sensitivity in discriminating between face and non-face patterns reduced only at the most extreme lighting directions. This tolerance to changes in the horizontal lighting direction depended partly on the orientation of the face, vertical lighting direction, and contrast polarity. Our results provide insight into how contrast cues produced by shading and shadows occurring across the facial surface are utilized by the visual system to detect human faces.

RESUMO

OBJECTIVE: To evaluate the effectiveness of a novel crescent-shaped tibial plateau-leveling osteotomy (TPLO) saw guide (crescent guide) to assist with saw control in novice participants. STUDY DESIGN: Ex vivo study. SAMPLE POPULATION: Synthetic bones (n = 54) and medium sized dog pelvic limbs (n = 36). METHODS: The 6 participants (interns and residents) without any prior experience performing a TPLO each performed 9 osteotomies on synthetic tibia models, and 6 osteotomies in cadaveric limbs of medium-sized dogs. Osteotomies made with the crescent guide were compared with those made with a standard jig and a radial saw guide with a jig. Osteotomy angulation, distance of eccentricity (DOE), and medial tibial cortical damage (synthetic bone models only) were measured from calibrated photographs. Participants rated their experiences with each technique. RESULTS: There was no difference in the DOE, coronal or axial osteotomy angulation between the 3 alignment devices for synthetic bone models or cadavers. Average medial cortical damage with the crescent guide (3.8 ± 7.3 mm2 ) was lower than with the radial guide (35.7 ± 27 mm2 ) and standard jig (51.2 ± 63.2 mm2 ) guides (P = <.01). Five of 6 participants preferred the crescent guide over the standard jig and radial guide. CONCLUSION: There was no difference in accuracy of osteotomy positioning but using the crescent guide resulted in lower cortical damage and more favorable participant perceptions. CLINICAL RELEVANCE: The crescent guide may improve control of the radial saw during TPLO in novice surgeons but does not appear to aid accurate osteotomy positioning.

RESUMO

While research tends to find an association of nurse staffing with quality in nursing homes, few studies examine complaints as a quality measure or account for ancillary staff. This study used federal nursing home complaint data to examine how key explanatory variables including nursing and ancillary staffing were associated with numbers of complaints and the likelihood of receiving a complaint. Results support that nursing home staffing is associated with quality. While direct care staffing was associated with fewer complaints, larger effects were found for social service and activities staffing. Increasing ancillary staffing may be a cost-effective way to reduce complaints.

RESUMO

PURPOSE: Little is known regarding the mutation profiles of ctDNA in the older adult breast cancer population. The objective of this study is to assess differences in mutation profiles in the older adult breast cancer population using a ctDNA assay as well as assess utilization of testing results. METHODS: Patients with advanced breast cancer underwent molecular profiling using a plasma-based ctDNA NGS assay (Guardant360) between 5/2015 and 10/2019 at Siteman Cancer Center. The profiling results of a multi-institutional database of patients with advanced breast cancer who had undergone molecular profiling were obtained. Associations between mutations and age group (≥ 65 vs. < 65) were examined using a Fisher's exact test. RESULTS: In the single-institutional cohort, 148 patients (69.2%) were < 65 years old and 66 patients (30.8%) ≥ 65 years old. ATM, BRAF, and PIK3CA mutations were found more frequently in older patients with ER + HER2- breast cancers (p < 0.01). In the multi-institutional cohort, 5367 (61.1%) were < 65 years old and 3417 (38.9%) ≥ 65 years old. ATM, PIK3CA, and TP53 mutations were more common in the older cohort (p < 0.0001) and MYC and GATA3 mutations were less common in the older cohort (p < 0.0001). CtDNA testing influenced next-line treatment management in 40 (19.8%) patients in the single-institutional cohort. CONCLUSION: When controlling for subtype, results from a single institution were similar to the multi-institutional cohort showing that ATM and PIK3CA were more common in older adults. These data suggest there may be additional molecular differences in older adults with advanced breast cancers.

RESUMO

PURPOSE: Patients with triple-negative breast cancer (TNBC) who do not achieve pathological complete response (pCR) following neoadjuvant chemotherapy have a high risk of recurrence and death. Molecular characterization may identify patients unlikely to achieve pCR. This neoadjuvant trial was conducted to determine the pCR rate with docetaxel and carboplatin and to identify molecular alterations and/or immune gene signatures predicting pCR. EXPERIMENTAL DESIGN: Patients with clinical stages II/III TNBC received 6 cycles of docetaxel and carboplatin. The primary objective was to determine if neoadjuvant docetaxel and carboplatin would increase the pCR rate in TNBC compared to historical expectations. We performed whole-exome sequencing (WES) and immune profiling on pre-treatment tumor samples to identify alterations that may predict pCR. Thirteen matching on-treatment samples were also analyzed to assess changes in molecular profiles. RESULTS: Fifty-eight of 127 (45.7%) patients achieved pCR. There was a non-significant trend toward higher mutation burden for patients with residual cancer burden (RCB) 0/I versus RCB II/III (median 80 versus 68 variants, p 0.88). TP53 was the most frequently mutated gene, observed in 85.7% of tumors. EGFR, RB1, RAD51AP2, SDK2, L1CAM, KPRP, PCDHA1, CACNA1S, CFAP58, COL22A1, and COL4A5 mutations were observed almost exclusively in pre-treatment samples from patients who achieved pCR. Seven mutations in PCDHA1 were observed in pre-treatment samples from patients who did not achieve pCR. Several immune gene signatures including IDO1, PD-L1, interferon gamma signaling, CTLA4, cytotoxicity, tumor inflammation signature, inflammatory chemokines, cytotoxic cells, lymphoid, PD-L2, exhausted CD8, Tregs, and immunoproteasome were upregulated in pre-treatment samples from patients who achieved pCR. CONCLUSION: Neoadjuvant docetaxel and carboplatin resulted in a pCR of 45.7%. WES and immune profiling differentiated patients with and without pCR. TRIAL REGISTRATION: Clinical trial information: NCT02124902, Registered 24 April 2014 & NCT02547987, Registered 10 September 2015.

RESUMO

BACKGROUND: Supervised physical activity interventions improve functional health during cancer survivorship, but remain costly and inaccessible for many. We previously reported on the benefits of a DVD-delivered physical activity program (FlexToBa™) in older adults. This is a secondary analysis of the intervention effects among cancer survivors in the original sample. METHODS: Low active, older adults who self-reported a history of cancer (N = 46; M time since diagnosis = 10.7 ± 9.4 years) participated in a 6-month, home-based physical activity intervention. Participants were randomized to either the DVD-delivered physical activity program focused on flexibility, toning, and balance (FlexToBa™; n = 22) or an attentional control condition (n = 24). Physical function was assessed by the Short Physical Performance Battery (SPPB) at baseline, end of intervention, and at 12 and 24 months after baseline. RESULTS: Repeated measures linear mixed models indicated a significant group*time interaction for the SPPB total score (ß = - 1.14, p = 0.048), driven by improved function from baseline to six months in the FlexToBa™ group. The intervention group also had improved balance (ß = - 0.56, p = 0.041) compared with controls. Similar trends emerged for the SPPB total score during follow-up; the group*time interaction from 0 to 12 months approached significance (ß = - 0.97, p = 0.089) and was significant from 0 to 24 months (ß = - 1.84, p = 0.012). No significant interactions emerged for other outcomes (ps > 0.11). CONCLUSIONS: A DVD-delivered physical activity intervention designed for cancer-free older adults was capable of eliciting and maintaining clinically meaningful functional improvements in a subgroup of cancer survivors, with similar effects to the original full sample. These findings inform the dissemination of evidence-based physical activity programs during survivorship. TRIAL REGISTRATION: ClinicalTrials.gov NCT01030419 . Registered 11 December 2009.

RESUMO

OBJECTIVE: To report the outcomes and complications associated with antibiotic-impregnated calcium sulfate beads for prevention and treatment of orthopedic-related surgical site infection (SSI) in companion animals. STUDY DESIGN: Retrospective case series. ANIMALS: Client-owned cats (n = 2) and dogs (n = 14). METHODS: Medical records of 16 cases in which implantation of antibiotic-impregnated calcium sulfate beads was performed for the prevention or treatment of SSI were reviewed. Information collected included signalment, prior surgery, reason for bead placement, antibiotics used, bacterial culture results, and clinical outcomes. RESULTS: Surgical site infection resolved in six of 10 animals treated therapeutically and did not occur in six of six animals treated prophylactically. Susceptibility of the causative bacteria to the antibiotic implanted was confirmed in five of six cases with resolved SSI treated therapeutically but in only one of four cases with unresolved SSI treated therapeutically. Complications directly related to bead placement were evident in only one case in which beads extruded from external skeletal fixator pin tracts 7 days after implantation. At final follow-up, 11 of 12 animals without SSI had satisfactory limb use and no clinical, cytologic, or radiographic evidence of infection. CONCLUSION: Implantation was well tolerated. Resolution of SSI was inconsistent; however, when bacteria were susceptible to the antibiotic implanted, SSI resolved in all but one case. CLINICAL SIGNIFICANCE: Antibiotic-impregnated calcium sulfate beads could be considered for prevention or treatment of orthopedic SSI in small animals. A prospective clinical study is required to obtain additional information, including the value of preoperative bacterial culture.

RESUMO

BACKGROUND: Advanced glycation end products (AGEs) are reactive metabolites produced as a by-product of sugar metabolism and are consumed through the diet in high-fat and highly processed foods. They are associated with chronic inflammatory diseases, and evidence suggests that they play a role in carcinogenesis. The authors evaluated the association of dietary AGE intake and the risk of postmenopausal invasive breast cancer. METHODS: This was a prospective cohort study of 183,548 postmenopausal women in the National Institutes of Health-AARP Diet and Health Study. The main outcome was incident invasive breast cancer. AGE intake was estimated from food-frequency questionnaires. Incident breast cancer cases were identified through state cancer registries. Cox proportional hazards regression models were used to estimate hazard ratios (HRs) and 95% confidence intervals for developing breast cancer according to AGE intake quintiles. Multivariable regression models were adjusted for breast cancer risk factors. RESULTS: The mean follow-up was 12.8 years, and 9851 breast cancers (1978 advanced stage) were identified. The median AGE daily intake was 5932 kilo units per 100 kilocalories (KU/1000 kcal). Women with higher intake tended to have lower education levels, higher body mass index, less physical activity, were current smokers, and had higher fat and meat intake. The highest quintile of AGE intake (compared with the lowest) was associated with an increased risk of breast cancer (HR, 1.09; 95% CI, 1.02-1.16; P = .03) after adjusting for breast cancer risk factors and particularly was associated with 37% of advanced-stage tumors (HR, 1.37; 95% CI, 1.09-1.74; P < .02) after adjusting for risk factors and fat and meat intake. CONCLUSIONS: Dietary AGEs may play a role in the development of postmenopausal breast cancer.

RESUMO

PURPOSE: Cutoffs of the 21-gene recurrence score (RS), a commonly used genomic assay for hormone receptor-positive breast cancer, have been updated. Little is known about racial/ethnic differences in RS results, RS-guided chemotherapy use, and outcomes on updated cutoff (RS ≥ 31 defined as high-risk) in the real-world setting. METHODS: A total of 81,937 women [75.0% whites, 7.7% blacks, 8.3% Asian American/Pacific Islanders (AAPIs), and 9.0% Hispanics] diagnosed with hormone receptor-positive breast cancer between 2004 and 2015, who received the 21-gene assay, were identified from the Surveillance, Epidemiology, and End Results. Logistic regressions estimated the race-associated odds ratios (ORs) of RS and chemotherapy use. Cox regressions estimated the race-associated hazard ratios (HRs) of breast cancer-specific and all-cause mortality. RESULTS: Compared with white women, black women were more likely to have RS-defined high-risk tumors (adjusted OR [aOR] 1.29; 95% CI 1.16-1.42). In high RS, blacks had lower odds of chemotherapy use (aOR 0.76; 95% CI 0.62-0.94) than whites, particularly among women ≥ 65 years (aOR 0.51; 95% CI 0.35-0.76), while AAPI and Hispanic women had no variation in chemotherapy use compared with whites in high RS. Black women had a higher risk of breast cancer-specific mortality (HR 1.37; 95% CI 1.12-1.67) and all-cause mortality compared with white women after adjusting for demographic and pathological factors, county-level socioeconomic deprivation, treatments and RS; AAPIs had lower mortality and Hispanics had similar mortality. CONCLUSIONS: Black women were more likely to have a high-risk RS tumor and less likely to receive chemotherapy in the group of high RS, especially those ≥ 65 years. Further studies are needed to identify barriers to chemotherapy in black patients with high RS scores.

RESUMO

BACKGROUND: Pathologic complete response (pCR) after neoadjuvant chemotherapy (NAC) for triple-negative breast cancer (TNBC) predicts decreased distant metastasis. However, most patients do not experience pCR, and other risk factors for distant metastasis after NAC are poorly characterized. This study investigated factors predictive of distant metastasis in TNBC without pCR after NAC. METHODS: Women with TNBC treated with NAC, surgery, and radiation therapy in 2000 through 2013 were reviewed. Freedom from distant metastasis (FFDM) was compared between patients with and without pCR using the Kaplan-Meier method. In patients without pCR, univariate and multivariable Cox analyses were used to determine factors predictive of distant metastasis. RESULTS: We identified 153 patients with median follow-up of 4.0 years (range, 0.5-14.0 years). After NAC, 108 had residual disease (pCR, 29%). Five-year FFDM was 98% and 55% in patients with and without pCR, respectively (P<.001). Factors independently predicting FFDM in patients without pCR were pathologic nodal positivity (hazard ratio, 3.08; 95% CI, 1.54-6.14; P=.001) and lymphovascular space invasion (hazard ratio, 1.91; 95% CI, 1.07-3.43; P=.030). Patients with a greater number of factors had worse FFDM; 5-year FFDM was 76.5% for patients with no factors (n=38) versus 54.9% and 27.5% for patients with 1 (n=44) and 2 factors (n=26), respectively (P<.001). CONCLUSIONS: Lack of pCR after NAC resulted in worse overall survival and FFDM, despite trimodality therapy.

RESUMO

The NCCN Guidelines for Survivorship provide screening, evaluation, and treatment recommendations for consequences of adult-onset cancer and its treatment, with the goal of helping healthcare professionals who work with survivors, including those in primary care. The guidelines also provide recommendations to help clinicians promote physical activity, weight management, and proper immunizations in survivors and facilitate care coordination to ensure that all of the survivors' needs are addressed. These NCCN Guidelines Insights summarize additions and changes made to the guidelines in 2020 regarding cardiovascular disease risk assessment and screening for subsequent primary malignancies.

RESUMO

This perspective addresses the challenges that assisted living (AL) providers face concerning federal guidelines to prevent increased spread of COVID-19. These challenges include restriction of family visitation, use of third-party providers as essential workers, staffing guidelines, transfer policies, and rural AL hospitalizations. To meet these challenges we recommend that AL providers incorporate digital technology to maintain family-resident communication. We also recommend that states adopt protocols that limit the number of AL communities visited by home health care workers in a 14-day period, appeal to the federal government for hazard pay for direct care workers, and to extend the personal care attendant program to AL. It is further recommended that states work with AL communities to implement COVID-19 comprehensive emergency management plans that are well-coordinated with local emergency operation centers to assist with transfers to COVID-19 specific locations and to assist in rural areas with hospital transfers. Together, these recommendations to AL providers and state and federal agencies address the unique structure and needs of AL and would enable AL communities to be better prepared to care for and reduce those infected with COVID-19.
