Mirror β-transitions should have similar strengths as long as binding energy, Coulomb energy and other explicitly breaking effects are small. However, large β-decay asymmetries have been observed in the decay of 9C [Phys. Rev. C 37 (1988) 766] and the decay of its mirror nucleus 9Li [Nucl. Phys. A 510 (1990) 189]. These asymmetries could be the indication of structural differences between mirror states. We have focussed on the beta-decays of 9C and 9Li to the high lying region (between 11-12 MeV) in the daughter nuclei 9B and 9Be. The difficulty in the study of these decays is that they are accompanied by the emission of three particles and one needs to determine the breakup mechanism to extract information about the position, width and feeding of the states. The β-decays of 9C [Nucl. Phys. A 692 (2001) 427] and 9Li [Phys. Lett. B. 576 (2003) 22] to the high lying region of the daughter nuclei have been remeasured with setups that allow the study of the complete kinematics of the processes and, hence, the breakup mechanism of the states in the daughter nuclei can be determined. The most recent experiments on 9C [Nucl. Phys. A 692 (2001) 427, Phys. Rev. C 61 (2000) 064310] gave BGT values of 1.58(16) and 1.20 (15) for the transition 9C → 9B (12.2 MeV) whereas the only early determination for 9Li→ 9Be (11.81 MeV) [Nucl. Phys. A 510 (1990) 189] gave 5.6 (1.2). The experiments on 9C employed coincidence detection of charged particles thereby allowing a detailed analysis, whereas the older 9Li experiment only included singles spectra. The only previous 9Li experiment where α-particle coincidences were measured [Nucl. Phys. A 366 (1981) 449] did not have sufficient angular resolution and no detailed analysis of the breakup mechanism was performed. [Copyright &y& Elsevier]

- Abstract
Background: The central nucleus of the amygdala (CeA) is part of the dopaminergic reward system and controls energy balance. Recently, a cluster of neurons was identified as responsive to the orexigenic effect of ghrelin and fasting. However, the signaling pathway by which ghrelin and fasting induce feeding is unknown. AMP-activated protein kinase (AMPK) is a cellular energy sensor, and its Thr172 phosphorylation (AMPKThr172) in the mediobasal hypothalamus regulates food intake. However, whether the expression and activation of AMPK in CeA could be one of the intracellular signaling activated in response to ghrelin and fasting eliciting food intake is unknown., Aim: To evaluate the activation of AMPK into CeA in response to ghrelin, fasting, and 2-deoxy-D-glucose (2DG) and whether feeding accompanied these changes. In addition, to investigate whether the inhibition of AMPK into CeA could decrease food intake., Methods: On a chow diet, eight-week-old Wistar male rats were stereotaxically implanted with a cannula in the CeA to inject several modulators of AMPKα1/2Thr172 phosphorylation, and we performed physiological and molecular assays., Key Findings: Fasting increased, and refeeding reduced AMPKThr172 in the CeA. Intra-CeA glucose injection decreased feeding, whereas injection of 2DG, a glucoprivation inductor, in the CeA, increased food intake and blood glucose, despite faint increases in AMPKThr172. Intra-CeA ghrelin injection increased food intake and AMPKThr172. To further confirm the role of AMPK in the CeA, chronic injection of Melanotan II (MTII) in CeA reduced body mass and food intake over seven days together with a slight decrease in AMPKThr172., Significance: Our findings identified that AMPK might be part of the signaling machinery in the CeA, which responds to nutrients and hormones contributing to feeding control. The results can contribute to understanding the pathophysiological mechanisms of altered feeding behavior/consumption, such as binge eating of caloric-dense, palatable food., Competing Interests: Declaration of competing interest None.

- Abstract
Introduction: Breast cancer screening (BCS) disparities leave historically underserved groups more vulnerable to adverse outcomes. This study explores granular associations between BCS and patient sociodemographic factors in a large urban safety-net health system., Methods: A retrospective review among female patients ages 50-74 within an urban safety-net health system was conducted in 2019. All patients had a primary care visit in the past 2 years. Multiple patient health and sociodemographic characteristics were reviewed, as well as provider gender and specialty. Bivariate analyses and multivariable logistic regression were performed in 2022., Results: The BCS rate among 11,962 women was 69.7%. Over half of patients were non-White (63.6%) and had public insurance (72.3%). Patients with limited English proficiency made up 44.3% of the cohort. Compared to their sociodemographic counterparts, patients with White race, English proficiency, and Medicare insurance had the lowest rates of BCS. Serious mental illness and substance use disorder were associated with lower odds of BCS. In multivariable analysis, when using White race and English speakers as a reference, most other races (Black, Hispanic, and Other) and languages (Spanish, Portuguese, and Other) had significantly higher odds of screening ranging from 8% to 63% higher, except Asian race and Haitian Creole language. Female (versus male) and internal medicine-trained providers were associated with higher screening odds., Conclusions: Multiple unique variables contribute to BCS disparities, influenced by patient and health system factors. Defining and understanding the interplay of these variables can guide policymaking and identify avenues to improve BCS for vulnerable or traditionally under-resourced populations., (Copyright © 2023 American Journal of Preventive Medicine.

- Abstract
Lobular neoplasia (LN) involves proliferative changes within the breast lobules. LN is divided into lobular carcinoma in situ (LCIS) and atypical lobular hyperplasia (ALH). LCIS can be further subdivided into three subtypes: classic LCIS, pleomorphic LCIS, and LCIS with necrosis (florid type). Because classic LCIS is now considered as a benign etiology, current guidelines recommend close follow-up with imaging versus surgical excision. The goal of our study was to determine if the diagnosis of classic LN on core needle biopsy (CNB) merits surgical excision. This is a retrospective, observational study conducted at Mount Auburn Hospital, Cambridge, MA, from May 17, 2017, through June 30, 2020. We reviewed the data of breast biopsies conducted at our hospital over this period and included patients who were diagnosed with classic LN (LCIS and/or ALH) and excluded patients having any other atypical lesions on CNB. All known cancer patients were excluded. Of the 2707 CNBs performed during the study period, we identified 68 women who were diagnosed with ALH or LCIS on CNB. CNB was performed for an abnormal mammogram in the majority of patients (60; 88%) while 7(10.3%) had an abnormal breast magnetic resonance imaging study (MRI), and 1 had an abnormal ultrasound (US). A total of 58 patients (85%) underwent excisional biopsy, of which 3 (5.2%) showed malignancy, including 2 cases of DCIS and 1 invasive carcinoma. In addition, there was 1 case (1.7%) with pleomorphic LCIS and 11 cases with ADH (15.5%). The management of LN found on core biopsy is evolving, with some advocating surgical excision and others recommending observation. Our data show a change in diagnosis with excisional biopsy in 13 (22.4%) of patients with 2 cases of DCIS, 1 invasive carcinoma, 1 pleomorphic LCIS, and 9 cases of ADH, diagnosed on excisional biopsy. While ALH and classic LCIS are considered benign, the choice of ongoing surveillance versus excisional biopsy should be made with shared decision making with the patient, with consideration of personal and family history, as well as patient preferences., Competing Interests: The authors declare that they have no conflicts of interest., (Copyright © 2023 Chinmay Jani et al.)

- Abstract
With the emergence of new variants of SARS-CoV-2, questions about transmissibility, vaccine efficacy, and impact on mortality are important to support decision-making in public health measures. Modifications related to transmissibility combined with the fact that much of the population has already been partially exposed to infection and/or vaccination, have stimulated recommendations to reduce the isolation period for COVID-19. However, these new guidelines have raised questions about their effectiveness in reducing contamination and minimizing impact in work environments. Therefore, a collaborative task force was developed to review the subject in a non-systematic manner, answering questions about SARS-CoV-2 variants, COVID-19 vaccines, isolation/quarantine periods, testing to end the isolation period, and the use of masks as mitigation procedures. Overall, COVID-19 vaccines are effective in preventing severe illness and death but are less effective in preventing infection in the case of the Omicron variant.

- Abstract
Purpose: Breast cancer is the most common cancer in women worldwide, representing 25.4% of the newly diagnosed cases in 2018. The past two decades have seen advancements in screening technologies, guidelines, and newer modalities of treatment. Our study reports and compares trends in breast cancer mortality in the European Union and the United Kingdom., Materials and Methods: We used the WHO Mortality Database. We extracted breast cancer mortality data from 2001 to 2017 on the basis of the International Classification of Diseases, 10th revision system. Crude mortality rates were dichotomized by sex and reported by year. We computed age-standardized death rates (ASDRs) per 100,000 population using the world standard population. Breast cancer mortality trends were compared using joinpoint regression analysis., Results: We analyzed data from 24 EU countries, including the United Kingdom. For women, breast cancer mortality was observed to be downtrending in all countries except Croatia, France, and Poland. For the most recent female data, the highest ASDR for breast cancer was identified in Croatia (19.29 per 100,000), and the lowest ASDR was noted in Spain (12.8 per 100,000). Denmark had the highest change in ASDR and the highest estimated annual percentage change of -3.2%. For men, breast cancer mortality decreased in 18 countries, with the largest relative reduction observed in Denmark with an estimated annual percentage change of -27.5%. For the most recent male data, the highest ASDR for breast cancer was identified in Latvia (0.54 per 100,000)., Conclusion: Breast cancer mortality rates have down trended in most EU countries between 2001 and 2017 for both men and women. Given the observational nature of this study, causality to the observed trends cannot be reliably ascribed. However, possible contributing factors should be considered and subject to further study., Competing Interests: Ingrid SalcicciolEmployment: DynamiCare Health Dominic C.

- Abstract
Research Questions: Can a previously defined relationship between sperm capacitation and the probability of a man generating pregnancy within three cycles, prospectively predict male fertility in diverse clinical settings? A second study asked, what is the prevalence of impaired sperm fertilizing ability in men questioning their fertility (MQF), and does this relate to traditional semen analysis metrics?, Design: In the multicentric, prospective observational study, data (n = 128; six clinics) were analysed to test a published relationship between the percentage of fertilization-competent, capacitated spermatozoa (Cap-Score) and probability of generating pregnancy (PGP) within three cycles of intrauterine insemination. Logistic regression of total pregnancy outcomes (n = 252) assessed fit. In the cohort comparison, Cap-Scores of MQF (n = 2155; 22 clinics) were compared with those of 76 fertile men., Results: New outcomes (n = 128) were rank-ordered by Cap-Score and divided into quintiles (25-26 per group); chi-squared testing revealed no difference between predicted and observed pregnancies (P = 0.809). Total outcomes (n = 252; 128 new + 124 previous) were pooled and the model recalculated, yielding an improved fit (P < 0.001). Applying the Akaike information criterion found that the optimal model used Cap-Score alone. Cap-Scores were performed on 2155 men (with semen analysis data available for 1948). To compare fertilizing ability, men were binned by PGP (≤19%, 20-29%, 30-39%, 40-49%, 50-59%, ≥60%). Distributions of PGP and the corresponding Cap-Scores were significantly lower in MQF versus fertile men (P < 0.001). Notably, 64% of MQF with normal volume, concentration and motility (757/1183) had PGP of 39% or less (Cap-Scores ≤31), versus 25% of fertile men., Conclusions: Sperm capacitation prospectively predicted male fertility. Impaired capacitation affects many MQF with normal semen analysis results, informing diagnosis versus idiopathic infertility., (Copyright © 2020 The Author(s). Published by Elsevier Ltd..

- Abstract
A previous study demonstrated that a high-fat diet (HFD), administered for one-three-days, induces hypothalamic inflammation before obesity's established, and the long term affects leptin signaling/action due to inflammation. We investigate whether exposure to particulate matter of a diameter of ≤2.5 μm (PM
2.5 ) in mice fed with a chow diet leads to similar metabolic effects caused by high-fat feeding. Compared to the filtered air group (FA), one-day-exposure-PM2.5 did not affect adiposity. However, five-days-exposure-PM2.5 increased hypothalamic microglia density, toll-like-receptor-4 (Tlr4), and the inhibitor-NF-kappa-B-kinase-epsilon (Ikbke) expression. Concurrently, fat mass, food intake (FI), and ucp1 expression in brown adipose tissue were also increased. Besides, decreased hypothalamic STAT3-phosphorylation and Pomc expression were found after twelve-weeks-exposure-PM2.5 . These were accompanied by increased FI and lower energy expenditure (EE), leading to obesity, along with increased leptin and insulin levels and HOMA. Mechanistically, the deletion of Tlr4 or knockdown of the Ikbke gene in the hypothalamus was sufficient to reverse the metabolic outcomes of twelve-weeks-exposure-PM2.5 . These data demonstrated that short-term exposure-PM2.5 increases hypothalamic inflammation, similar to a HFD. Long-term exposure-PM2.5 is even worse, leading to leptin resistance, hyperphagia, and decreased EE. These effects are most likely due to chronic hypothalamic inflammation, which is regulated by Tlr4 and Ikbke signaling.- Published

- Abstract
Introduction: Khorana score (KS) stratifies patients into low, intermediate, and high risk groups for venous thromboembolism (VTE). We examined the generalizability of the KS to risk of VTE and association with mortality., Methods: A retrospective cohort study was conducted at Mount Auburn Hospital, Cambridge, Massachusetts. Patients aged 18 years or older undergoing chemotherapy were included. All patients were evaluated for a six-month period. Primary study endpoints were VTE or mortality., Results: Some 277 participants were included with a mean age of 63.95 (standard deviation, SD ± 12.47). The incidence proportion was 6.13% and a total of 17 VTE events were reported over a 2.5-year period. Compared to those with a low KS (0), those with a high KS (3 or above) had 6.4 times (p=0.032) while with an intermediate KS (1-2) had 2.6 times the odds of having a VTE event (p=0.22). Those who had a VTE had 4.03 times the odds of death compared to those who did not have a VTE (p=0.006). Compared to those with a low KS, those with a high KS had 5.7 times (p=0.02) the odds of six-month mortality and 5.04 odds (p=0.001) of mortality at any time., Conclusion: High KS was associated with increased odds of VTE and mortality in our study., Competing Interests: The authors have declared that no competing interests exist., (Copyright © 2020, Ahmed et al.)

- Abstract
Background: Antiretroviral therapy (ART) has decreased AIDS incidence and mortality, rendering comorbidities, such as hepatitis B more relevant for people living with human immunodeficiency virus (HIV). Since antiretroviral drugs may also inhibit hepatitis B virus (HBV) replication, analyzing the impact of ART on management of hepatitis B in this population is important., Objective: To assess HBV viremia among HIV/HBV coinfected individuals on ART and its associated factors., Method: For this cross-sectional study, HIV/HBV-coinfected individuals, aged over 18 years, who were on ART for over six months and receiving care at an outpatient clinic in São Paulo were recruited. Sociodemographic characteristics, information about viral exposure, clinical and laboratory data, including evaluation of liver fibrosis were obtained. Plasma HBV DNA was measured by polymerase chain reaction. Viral genome sequencing was conducted for genotyping and identification of drug resistance-conferring mutations if viral load exceeded 900 IU/mL., Results: Out of 2,946 patients who attended the clinic in 2015, 83 were eligible and 56 evaluated. Plasma HBV DNA was detected in 16 (28.6%) (95% CI: 18.0-41.3%), all on lamivudine and tenofovir treatment. HBV DNA detection was associated with lower education (p = 0.015), higher international normalized ratios (p = 0.045), history of an AIDS-defining illness [OR: 3.43 (95% CI: 1.10-11.50)], and HBeAg detection [OR: 6.60 (95% CI: 1.84-23.6)]. In contrast, a last CD4+ count above 500 cells/mm
3 in the year prior to inclusion [OR: 0.18 (95% CI: 0.04-0.71)] and detection of anti-HBe [OR: 0.21 (95% CI: 0.04-0.99)] were negatively associated. Patients with HBV DNA above 900 IU/mL were infected with subgenotypes A1 (n = 3) and D2 (n = 1), and exhibited viral mutations associated with total resistance to lamivudine and partial resistance to entecavir., Conclusions: Despite being on ART, a significant proportion of HIV/HBV-coinfected individuals present HBV viremia. Characterization of factors that are associated with this finding may help professionals provide better management to these patients., (Copyright © 2019 Sociedade Brasileira de Infectologia.

- Abstract
Purpose: There is very little data on the effect of combining methods to better predict and improve oral antineoplastic adherence in cancer patients. The goal of this study was to evaluate the effectiveness of an intensive pharmacist intervention at the beginning of oral antineoplastic therapy versus nurse-led control group on adherence., Methods: This was a prospective, randomized, open-label controlled trial performed in a single center hematology/oncology outpatient service to compare the effectiveness of repetitive pharmacist educational intervention on adherence rates measured at four and eight weeks after prescribing oral antineoplastic medication compared to a nurse-led control group. Both groups included investigator pill counts and self-report adherence questionnaires., Results: Two-hundred patients were enrolled between 2009 and 2015. Fourteen of the 101 (14%) patients in the pharmacist group and 7 (7%) of the 99 patients in the nurse-led control group dropped out ( p = 0.166). The majority of patients who remained in the study were 90-100% adherent to oral antineoplastic therapy in both groups. The pharmacist group slightly underperformed at Pill Count 2, possibly due to barriers for non-adherence. Statistically significant correlations associated with non-adherence were forgetfulness ( p = 0.009), wanting to avoid side effects ( p = 0.02), feeling depressed or overwhelmed ( p = 0.032), or falling asleep before taking medication ( p = 0.048) in both groups., Conclusion: The combination of pill count and patient self-report adherence is a way of improving oral antineoplastic adherence. However, significant barriers to adherence were identified such as forgetfulness, wanting to avoid side effects, feeling depressed or overwhelmed, and falling asleep before taking medications.

- Abstract
Objective: Recent data show that iNOS has an essential role in ER stress in obesity. However, whether iNOS is sufficient to account for obesity-induced ER stress and Unfolded Protein Response (UPR) has not yet been investigated. In the present study, we used iNOS knockout mice to investigate whether high-fat diet (HFD) can still induce residual ER stress-associated insulin resistance., Methods: For this purpose, we used the intraperitoneal glucose tolerance test (GTT), euglycemic-hyperinsulinemic clamp, western blotting and qPCR in liver, muscle, and adipose tissue of iNOS KO and control mice on HFD., Results: The results of the present study demonstrated that, in HFD fed mice, iNOS-induced alteration in insulin signaling is an essential mechanism of insulin resistance in muscle, suggesting that iNOS may represent an important target that could be blocked in order to improve insulin sensitivity in this tissue. However, in liver and adipose tissue, the insulin resistance induced by HFD was only partially dependent on iNOS, and, even in the presence of genetic or pharmacological blockade of iNOS, a clear ER stress associated with altered insulin signaling remained evident in these tissues. When this ER stress was blocked pharmacologically, insulin signaling was improved, and a complete recovery of glucose tolerance was achieved., Conclusions: Taken together, these results reinforce the tissue-specific regulation of insulin signaling in obesity, with iNOS being sufficient to account for insulin resistance in muscle, but in liver and adipose tissue ER stress and insulin resistance can be induced by both iNOS-dependent and iNOS-independent mechanisms.

Missbach B, Florack A, Weissmann L, and König J
- Abstract
Research has shown that imagining food consumption leads to food-specific habituation effects. In the present research, we replicated these effects and further examined whether the depletion of self-regulatory resources would reduce the habituation effects of imagined food consumption. Since self-regulatory resources have been shown to reduce habituation effects during the perception of emotional stimuli, we expected a reduction in habituation effects from imagined food consumption when self-regulatory resources were depleted. In Study 1, we replicated habituation effects as a response to imagining gummy bear consumption with a high (36) and medium number (18) of repetitions in a camouflaged taste test. Participants imagining gummy bear intake showed decreased food intake compared with participants who imagined putting a coin into a laundry machine. The number of repetitions did not significantly moderate the observed habituation effect. In Study 2, we investigated whether self-regulatory depletion would impede habituation effects evoked by the imagination of walnut consumption. Participants in a depleted state did not show a reduction in food intake after imagining walnut intake compared with participants in a non-depleted state. We discuss directions for future research and processes that might underlie the observed moderating effect of self-regulatory resources.

- Abstract
IKK epsilon (IKKε) is induced by the activation of nuclear factor-κB (NF-κB). Whole-body IKKε knockout mice on a high-fat diet (HFD) were protected from insulin resistance and showed altered energy balance. We demonstrate that IKKε is expressed in neurons and is upregulated in the hypothalamus of obese mice, contributing to insulin and leptin resistance. Blocking IKKε in the hypothalamus of obese mice with CAYMAN10576 or small interfering RNA decreased NF-κB activation in this tissue, relieving the inflammatory environment. Inhibition of IKKε activity, but not TBK1, reduced IRS-1(Ser307) phosphorylation and insulin and leptin resistance by an improvement of the IR/IRS-1/Akt and JAK2/STAT3 pathways in the hypothalamus. These improvements were independent of body weight and food intake. Increased insulin and leptin action/signaling in the hypothalamus may contribute to a decrease in adiposity and hypophagia and an enhancement of energy expenditure accompanied by lower NPY and increased POMC mRNA levels. Improvement of hypothalamic insulin action decreases fasting glycemia, glycemia after pyruvate injection, and PEPCK protein expression in the liver of HFD-fed and db/db mice, suggesting a reduction in hepatic glucose production. We suggest that IKKε may be a key inflammatory mediator in the hypothalamus of obese mice, and its hypothalamic inhibition improves energy and glucose metabolism., (© 2014 by the American Diabetes Association.
