Sexual assault of the older person: Attendances to the Republic of Ireland's sexual assault treatment unit network.

BACKGROUND: Sexual assault (SA) poses a threat to all areas of contemporary society. Although older individuals represent a vulnerable demographic, a considerable gap exists in the literature regarding the context in which older individuals experience SA. This study aims to provide a comprehensive description of older individuals' attendances at the Sexual Assault Treatment Unit (SATU) network in the Republic of Ireland. METHODS: A 7-year national cross-sectional study was performed to analyse the attendances of older people (≥65 years old) to the SATU network, and to compare them with younger attendances (<65 years old), with a more in-depth subset analysis of Dublin SATU attendances. RESULTS: During the study period, there were 6478 attendances to the SATU network, of which 0.93 % (n = 60) were older people. These included 59 females and 1 male, with the average age of 76.05 years ± 8.16. Forensic examinations were performed in 81.7 %, with the majority seeking assistance within 7 days (80 %). Comparison of older (≥65 years) and younger (<65 years) attendees revealed older individuals were more uncertain whether a sexual assault had occurred (35.5 % vs. 14.4 %, p < 0.001) but more likely to report the incident to the police (78.3 % vs. 64.3 %, p = 0.02). Assault by a person in authority was significantly more common in older age groups (11.7 % vs. 1.8 %, p < 0.001). Older individuals were significantly more likely to be assaulted in their own home (33.3 % vs. 21.5 p < 0.03) or in 'other-indoors' settings (e.g. nursing home/hospital) (43.3 % vs. 23.4 % p < 0.001). They were less likely to be assaulted in the assailant's home (5.0 % vs. 22.9 %, p < 0.001) or outdoors (5.0 % vs. 19.7 %, p = 0.004). In our subset analysis of 19 cases, 73.7 % occurred in healthcare facilities, 63.2 % had dementia, and 42.1 % were care dependent. Genital injuries were present in 44.4 % of patients and extra-genital injuries in 22.2 %. CONCLUSION: Unique patterns are evident in sexual assault experienced by older people, underscoring the necessity for tailored interventions and effective support systems for reporting and addressing this vulnerable demographic. This is especially crucial in healthcare environments, where a notable proportion of cases occur, frequently involving individuals with dementia and requiring care assistance.

Search for Evidence of Baryogenesis and Dark Matter in B

A new dark sector antibaryon, denoted ψ_{D}, could be produced in decays of B mesons. This Letter presents a search for B^{+}→ψ_{D}+p (and the charge conjugate) decays in e^{+}e^{-} annihilations at 10.58 GeV, using data collected in the BABAR experiment. Data corresponding to an integrated luminosity of 398 fb^{-1} are analyzed. No evidence for a signal is observed. Branching fraction upper limits in the range from 10^{-7}-10^{-5} are obtained at 90% confidence level for masses of 1.0

Search for an Axionlike Particle in B Meson Decays.

Axionlike particles (ALPs) are predicted in many extensions of the standard model, and their masses can naturally be well below the electroweak scale. In the presence of couplings to electroweak bosons, these particles could be emitted in flavor-changing B meson decays. We report herein a search for an ALP, a, in the reaction B^{±}→K^{±}a, a→γγ using data collected by the BABAR experiment at SLAC. No significant signal is observed, and 90% confidence level upper limits on the ALP coupling to electroweak bosons are derived as a function of ALP mass, improving current constraints by several orders of magnitude in the range 0.175 GeV

Search for Lepton Flavor Violation in ϒ(3S)→e

We report on the first search for electron-muon lepton flavor violation (LFV) in the decay of a b quark and b antiquark bound state. We look for the LFV decay ϒ(3S)→e^{±}µ^{∓} in a sample of 118 million ϒ(3S) mesons from 27 fb^{-1} of data collected with the BABAR detector at the SLAC PEP-II e^{+}e^{-} collider operating with a 10.36 GeV center-of-mass energy. No evidence for a signal is found, and we set a limit on the branching fraction B[ϒ(3S)→e^{±}µ^{∓}]<3.6×10^{-7} at 90% C. L. This result can be interpreted as a limit Λ_{NP}/g_{NP}^{2}>80 TeV on the energy scale Λ_{NP} divided by the coupling-squared g_{NP}^{2} of relevant new physics (NP).

Search for Darkonium in e

Collider searches for dark sectors, new particles interacting only feebly with ordinary matter, have largely focused on identifying signatures of new mediators, leaving much of dark sector structures unexplored. In particular, the existence of dark matter bound states (darkonia) remains to be investigated. This possibility could arise in a simple model in which a dark photon (A^{'}) is light enough to generate an attractive force between dark fermions. We report herein a search for a J^{PC}=1^{--} darkonium state, the ϒ_{D}, produced in the reaction e^{+}e^{-}→γϒ_{D}, ϒ_{D}→A^{'}A^{'}A^{'}, where the dark photons subsequently decay into pairs of leptons or pions, using 514 fb^{-1} of data collected with the BABAR detector. No significant signal is observed, and we set bounds on the γ-A^{'} kinetic mixing as a function of the dark sector coupling constant for 0.001

Third-trimester growth diversity in small fetuses classified as appropriate-for-gestational age or small-for-gestational age at birth.

OBJECTIVE: We have shown previously that third-trimester growth in small fetuses (estimated fetal weight (EFW) < 10th percentile) with birth weight (BW) < 10th percentile is heterogeneous using individualized growth assessment (IGA). We aimed to test our hypothesis that individual growth patterns in small fetuses with BW > 10th percentile are also variable but in different ways. METHODS: This was a study of 191 cases with EFW < 10th percentile and BW > 10th percentile (appropriate-for-gestational-age (AGA) cohort), derived from the PORTO study. Composite size parameters were used to quantify growth pathology at individual third-trimester timepoints (individual composite prenatal growth assessment score (-icPGAS)). The fetal growth pathology score 1 (-FGPS1), calculated cumulatively from serial -icPGAS values, was used to characterize third-trimester growth patterns. Vascular-system evaluation included umbilical artery (UA) and middle cerebral artery (MCA) Doppler velocimetry. Outcome variables were birth age (preterm/term delivery) and BW (expressed as growth potential realization index for weight (GPRIWT ) and percentile). The findings from the AGA cohort were compared with those from small fetuses (EFW < 10th percentile) with BW < 10th percentile (small-for-gestational-age (SGA) cohort). RESULTS: The AGA cohort was found to have 134 fetuses (70%) with normal growth pattern and 57 (30%) with growth restriction based on IGA criteria. Seven growth-restriction -FGPS1 patterns were observed, including the previously defined progressive, late, adaptive and recovering types. The recovering type was the most common growth pattern in the AGA cohort (50.9%). About one-third of fetuses without any evidence of growth restriction had significant unexplained abnormalities in the UA (34%) and MCA (31%) and elevated mean GPRIWT values (113 ± 12.5%). Comparison of the AGA and SGA cohorts indicated a significant difference in the distribution of -FGPS1 growth patterns (P = 0.0001). Compared with the SGA cohort, the AGA cohort had more fetuses with a normal growth pattern (70% vs 38%) and fewer cases with growth restriction (30% vs 62%). While the recovering type was the most common growth-restriction pattern in the AGA cohort (51%), the progressive type was the primary growth-restriction pattern in the SGA cohort (44%). No difference in the incidence of MCA or UA abnormality was found between the SGA and AGA cohorts when comparing subgroups of more than 10 fetuses. CONCLUSIONS: Both normal-growth and growth-restriction patterns were observed in the AGA cohort using IGA, as seen previously in the SGA cohort. The seven types of growth restriction defined in the SGA cohort were also identified in AGA cases, but their distribution was significantly different. In one-third of cases without evidence of growth pathology in the AGA cohort, Doppler abnormalities in the UA and MCA were seen. This heterogeneity underscores the difficulty of accurate classification of fetal and neonatal growth status using conventional population-based methods. © 2021 International Society of Ultrasound in Obstetrics and Gynecology.

Search for a Dark Leptophilic Scalar in e

Many scenarios of physics beyond the standard model predict the existence of new gauge singlets, which might be substantially lighter than the weak scale. The experimental constraints on additional scalars with masses in the MeV to GeV range could be significantly weakened if they interact predominantly with leptons rather than quarks. At an e^{+}e^{-} collider, such a leptophilic scalar (ϕ_{L}) would be produced predominantly through radiation from a τ lepton. We report herein a search for e^{+}e^{-}→τ^{+}τ^{-}ϕ_{L}, ϕ_{L}→ℓ^{+}ℓ^{-} (ℓ=e, µ) using data collected by the BABAR experiment at SLAC. No significant signal is observed, and we set limits on the ϕ_{L} coupling to leptons in the range 0.04

Prenatally Diagnosed Fetal Aneuploidy: Natural History and Subsequent Management.

Aims Our aim was to determine the number of cases of aneuploidy which were prenatally diagnosed in our tertiary referral unit from 2005-2015 and to analyse the subsequent outcomes of Trisomies 13, 18 and 21(T13, T18 and T21). Methods This was a retrospective observational study. We firstly determined the total number of prenatally diagnosed aneuploidies. We then analysed their subsequent outcomes including average gestation at miscarriage or IUD, mode of delivery and neonatal outcome. Results 402 cases of T13, T18 or T21 were identified of which 40% opted for expectant management. T18 was the most likely diagnosis to result in miscarriage, IUD or intrapartum death. The highest caesarean delivery rate was in T21. Conclusion With regards to T13 and T18, live birth rates show that some parents may achieve the goal of spending time with their baby in the immediate postpartum period. This information will act as a valuable resource in our counselling.

Measurements of the Absolute Branching Fractions of B

A study of the two-body decays B^{±}→X_{cc[over ¯]}K^{±}, where X_{cc[over ¯]} refers to one charmonium state, is reported by the BABAR Collaboration using a data sample of 424 fb^{-1}. The absolute determination of branching fractions for these decays are significantly improved compared to previous BABAR measurements. Evidence is found for the decay B^{+}→X(3872)K^{+} at the 3σ level. The absolute branching fraction B[B^{+}→X(3872)K^{+}]=[2.1±0.6(stat)±0.3(syst)]×10^{-4} is measured for the first time. It follows that B[X(3872)→J/ψπ^{+}π^{-}]=(4.1±1.3)%, supporting the hypothesis of a molecular component for this resonance.

Search for Rare or Forbidden Decays of the D

We present a search for nine lepton-number-violating and three lepton-flavor-violating neutral charm decays of the type D^{0}→h^{'-}h^{-}ℓ^{'+}ℓ^{+} and D^{0}→h^{'-}h^{+}ℓ^{'±}ℓ^{∓}, where h and h^{'} represent a K or π meson and ℓ and ℓ^{'} an electron or muon. The analysis is based on 468 fb^{-1} of e^{+}e^{-} annihilation data collected at or close to the ϒ(4S) resonance with the BABAR detector at the SLAC National Accelerator Laboratory. No significant signal is observed for any of the twelve modes, and we establish 90% confidence level upper limits on the branching fractions in the range (1.0-30.6)×10^{-7}. The limits are between 1 and 3 orders of magnitude more stringent than previous measurements.

Publication trends in hidradenitis suppurativa from 2008 to 2018.

BACKGROUND: Increased interest in hidradenitis suppurativa (HS) research is encouraging. A critical analysis of the state of HS literature may demonstrate the strength of existing knowledge and highlight current gaps. OBJECTIVES: To analyse changes in HS literature from 2008 to 2018 with focus on quantity and quality of annual publications. METHODS: Review of all indexed publications reporting on HS on PubMed. Publications were categorized based on study design, study topic and treatment type where applicable. Publications were dichotomized into high level of evidence and low level of evidence groups. Linear regression analyses were performed to investigate the change in publication number over time. Annual average growth rate and distribution of high versus low level of evidence publications were calculated. RESULTS: Publication number increased over time overall (R2  = 0.64, P = 0.003) and for all publication types except randomized clinical trials. Case reports and case series represented the majority of HS publications (n = 479, 40.3%). Treatment was the main focus of publications (n = 445, 37.6%) with increasing interest in medical management evident in recent years. Distribution of low level of evidence studies (n = 974) compared with high level of evidence studies over time (n = 209) was significant (x2 : 11.45, P = 0.0007). High level of evidence studies had a higher average annual growth rate (49.9%) compared with low level of evidence studies (23.7%). Few randomized clinical trials were performed (n = 16), focusing equally on medical or procedural treatments. CONCLUSIONS: Hidradenitis suppurativa research is undergoing a tremendous shift, suggesting rapid maturation of the field. Current HS literature, however, remains primarily based on limited clinical observation data, with a particular lack of randomized clinical trials. Despite this, the increase in high level of evidence studies is encouraging and may herald a shift towards improved disease understanding and treatment paradigms.

Precision Measurement of the Ratio B(ϒ(3S)→τ

We report on a precision measurement of the ratio R_{τµ}^{ϒ(3S)}=B(ϒ(3S)→τ^{+}τ^{-})/B(ϒ(3S)→µ^{+}µ^{-}) using data collected with the BABAR detector at the SLAC PEP-II e^{+}e^{-} collider. The measurement is based on a 28 fb^{-1} data sample collected at a center-of-mass energy of 10.355 GeV corresponding to a sample of 122 million ϒ(3S) mesons. The ratio is measured to be R_{τµ}^{ϒ(3S)}=0.966±0.008_{stat}±0.014_{syst} and is in agreement with the standard model prediction of 0.9948 within 2 standard deviations. The uncertainty in R_{τµ}^{ϒ(3S)} is almost an order of magnitude smaller than the only previous measurement.

Extraction of form Factors from a Four-Dimensional Angular Analysis of B[over ¯]→D

An angular analysis of the decay B[over ¯]→D^{*}ℓ^{-}ν[over ¯]_{ℓ}, ℓ∈{e,µ}, is reported using the full e^{+}e^{-} collision data set collected by the BABAR experiment at the ϒ(4S) resonance. One B meson from the ϒ(4S)→BB[over ¯] decay is fully reconstructed in a hadronic decay mode, which constrains the kinematics and provides a determination of the neutrino momentum vector. The kinematics of the semileptonic decay is described by the dilepton mass squared, q^{2}, and three angles. The first unbinned fit to the full four-dimensional decay rate in the standard model is performed in the so-called Boyd-Grinstein-Lebed approach, which employs a generic q^{2} parametrization of the underlying form factors based on crossing symmetry, analyticity, and QCD dispersion relations for the amplitudes. A fit using the more model-dependent Caprini-Lellouch-Neubert (CLN) approach is performed as well. Our form factor shapes show deviations from previous fits based on the CLN parametrization. The latest form factors also provide an updated prediction for the branching fraction ratio R(D^{*})≡B(B[over ¯]→D^{*}τ^{-}ν[over ¯]_{τ})/B(B[over ¯]→D^{*}ℓ^{-}ν[over ¯]_{ℓ})=0.253±0.005. Finally, using the well-measured branching fraction for the B[over ¯]→D^{*}ℓ^{-}ν[over ¯]_{ℓ} decay, a value of |V_{cb}|=(38.36±0.90)×10^{-3} is obtained that is consistent with the current world average for exclusive B[over ¯]→D^{(*)}ℓ^{-}ν[over ¯]_{ℓ} decays and remains in tension with the determination from inclusive semileptonic B decays to final states with charm.

Observation of the Decay D

We report the observation of the rare charm decay D^{0}→K^{-}π^{+}e^{+}e^{-}, based on 468 fb^{-1} of e^{+}e^{-} annihilation data collected at or close to the center-of-mass energy of the ϒ(4S) resonance with the BABAR detector at the SLAC National Accelerator Laboratory. We find the branching fraction in the invariant mass range 0.675

Search for a Stable Six-Quark State at BABAR.

Recent investigations have suggested that the six-quark combination uuddss could be a deeply bound state (S) that has eluded detection so far, and a potential dark matter candidate. We report the first search for a stable, doubly strange six-quark state in ϒ→SΛ[over ¯]Λ[over ¯] decays based on a sample of 90×10^{6}ϒ(2S) and 110×10^{6}ϒ(3S) decays collected by the BABAR experiment. No signal is observed, and 90% confidence level limits on the combined ϒ(2S,3S)→SΛ[over ¯]Λ[over ¯] branching fraction in the range (1.2-1.4)×10^{-7} are derived for m_{S}<2.05 GeV. These bounds set stringent limits on the existence of such exotic particles.

Systematic review of endovascular intervention and surgery for common femoral artery atherosclerotic disease.

BACKGROUND: Endovascular intervention has emerged as a potential alternative to open surgery in treating common femoral artery (CFA) atherosclerotic disease. The aim of this systematic review was to assess the safety and efficacy of both techniques. METHODS: Thirteen electronic databases from 1980 to 3 January 2018 were searched. Study quality was assessed using the National Institute for Health and Care Excellence Interventional Procedure Programme quality assessment tool. Safety and efficacy outcome measures were analysed. RESULTS: Thirty-one studies reporting 813 endovascular procedures and 3835 endarterectomies were included. Only two small RCTs have been reported. The methodological quality of available studies was generally low and follow-up short. Safety endpoint assessment revealed a similar risk of wound haematoma for endovascular intervention and endarterectomy (5·5 (95 per cent c.i. 0·2 to 17·2) versus 3·9 (1·7 to 6·9) per cent respectively), a lower risk of wound infection with endovascular procedures (0 versus 5·9 (3·4 to 9·0) per cent) and a lower risk of wound lymph leakage (0 versus 5·7 (3·3 to 8·6) per cent). Efficacy endpoint assessment at 1 year identified that endovascular intervention had a lower primary patency rate than endarterectomy (78·8 (73·3 to 83·8) versus 96·0 (92·2 to 98·6) per cent respectively), a higher revascularization rate (16·0 (6·1 to 29·4) versus 5·8 (1·0 to 14·2) per cent) and a similar amputation rate (2·7 (1·2 to 4·8) versus 1·9 (0·7 to 3·8) per cent). CONCLUSION: Endovascular intervention of CFA disease appears to reduce the risk of wound complications but is associated with a lower patency rate and increased rates of subsequent revascularization procedures. Standardization of the endovascular technique and quantification of the proportions of patients suitable for either technique are required.

Measurement of the D

We measure the mass difference, Δm_{+}, between the D^{*}(2010)^{+} and the D^{+} using the decay chain D^{*}(2010)^{+}→D^{+}π^{0} with D^{+}→K^{-}π^{+}π^{+}. The data were recorded with the BABAR detector at center-of-mass energies at and near the ϒ(4S) resonance, and correspond to an integrated luminosity of approximately 468 fb^{-1}. We measure Δm_{+}=(140 601.0±6.8[stat]±12.9[syst]) keV. We combine this result with a previous BABAR measurement of Δm_{0}≡m(D^{*}(2010)^{+})-m(D^{0}) to obtain Δm_{D}=m(D^{+})-m(D^{0})=(4824.9±6.8[stat]±12.9[syst]) keV. These results are compatible with and approximately five times more precise than the Particle Data Group averages.
