The Role of County-Level Persistent Poverty in Stroke Mortality in the USA.

Stroke is a major health concern in the USA, disproportionately affecting socioeconomically disadvantaged groups. This study investigates the link between persistent poverty and stroke mortality rates in residents aged 65 and above, positing that sustained economic challenges at the county level correlate with an increase in stroke-related deaths. Persistent poverty refers to a long-term state where a significant portion of a population lives below the poverty threshold for an extended period, typically measured over several decades.

Analysis of factors associated with the failure of treatment in thoracolumbar burst fractures treated with short-segment posterior spinal fixation.

Background: The treatment of thoracolumbar burst fractures continues to pose challenges. Although short-segment posterior spinal fixation (SSPSF) has shown satisfactory clinical outcomes, it is accompanied by a relatively high rate of treatment failure. This study aimed to assess factors associated with treatment failure in thoracolumbar burst fractures treated with SSPSF.

How do classroom-turnover times depend on lecture-hall size?

Academic spaces in colleges and universities span classrooms for 10 students to lecture halls that hold over 600 people. During the break between consecutive classes, students from the first class must leave and the new class must find their desks, regardless of whether the room holds 10 or 600 people. Here we address the question of how the size of large lecture halls affects classroom-turnover times, focusing on non-emergency settings.

This study aimed to assess the predictors of in-hospital mortality of elderly patients with moderate to severe TBI who presented during the Coronavirus disease 2019 (COVID-19) pandemic.

Methods: In this retrospective analytical study, all elderly patients with moderate to severe TBI who were referred to our center between March 2nd, 2020 to August 1st, 2020 were investigated and compared against the TBI patients receiving treatment during the same time period within the year 2019.

"Triple-Decker Sandwich" Containing Planar {BEPd} Ring (E = S or Se).

In an effort to generate triple-decker complexes comprising a {PdCl}moiety in the middle deck, we have explored the reactivity of [(Cp*M){μ-BHE}], - (: M = Co, E = S; : M = Co, E = Se; : M = Rh, E = Se; and : M = Ir, E = Se; Cp* = η-CMe), with [PdCl(COD)] (COD = 1,5-cyclooctadiene). The reactions led to the formation of a series of trinuclear heterometallic triple-decker complexes, [(Cp*M){μ-BHEPd(Cl)}], - (: M = Co, E = S; : M = Co, E = Se; : M = Rh, E = Se; and : M = Ir, E = Se). Formation of the complexes - occurred almost instinctively as a single product with the elimination of the COD ligand.

Chalcogen Stabilized bis-Hydridoborate Complexes of Cobalt: Analogues of Tetracyclo[4.3.0.0 .0 ]nonane.

Treatment of Li[BH ER] (E=Se or Te, R=Ph; E=S, R=CH Ph) with [Cp*CoCl] led to the formation of hydridoborate complexes, [{CoCp*Ph}{Cp*Co}{μ-EPh}{μ-κ -E,H-EBH }], 1a and 1 b (1 a: E=Se; 1 b: E=Te) and a bis-hydridoborate species [Cp*Co{μ-κ -Se,H-SeBH }] , 2. All the complexes, 1 a, 1 b and 2 are stabilized by β-agostic type interaction in which 1 b represents a novel bimetallic borate complex with a rare B-Te bond. QTAIM analysis furnished direct proof for the existence of a shared and dative B-chalcogen and Co-chalcogen interactions, respectively.

Trithia-diborinane and Bis(bridging-boryl) Complexes of Ruthenium Derived from a [BH(SCHS)] Ion.

The field of diborinane is sparsely explored area, and not many compounds are structurally characterized. The room-temperature reaction of [{Cp*RuCl(μ-Cl)}] (Cp* = η-CMe) with Na[BH(SCHS)] yielded ruthenium dithioformato [{Cp*Ru(μ,η-SCHS)}], 1, and 1-thioformyl-2,6-tetrahydro-1,3,5-trithia-2,6-diborinane complex, [(Cp*Ru){(η-SCHS)CHS(BH)}], 2. To investigate the reaction pathway for the formation of 2, we carried out the reaction of [(BH)(CHS)], 3, with 1 that yielded compound 2.

Health Spending By State 1991-2014: Measuring Per Capita Spending By Payers And Programs.

As the US health sector evolves and changes, it is informative to estimate and analyze health spending trends at the state level. These estimates, which provide information about consumption of health care by residents of a state, serve as a baseline for state and national-level policy discussions. This study examines per capita health spending by state of residence and per enrollee spending for the three largest payers (Medicare, Medicaid, and private health insurance) through 2014.

η(4) -HBCC-σ,π-Borataallyl Complexes of Ruthenium Comprising an Agostic Interaction.

Thermolysis of [Cp*Ru(PPh2 (CH2 )PPh2 )BH2 (L2 )] 1 (Cp*=η(5) -C5 Me5 ; L=C7 H4 NS2 ), with terminal alkynes led to the formation of η(4) -σ,π-borataallyl complexes [Cp*Ru(μ-H)B{R-C=CH2 }(L)2 ] (2 a-c) and η(2) -vinylborane complexes [Cp*Ru(R-C=CH2 )BH(L)2 ] (3 a-c) (2 a, 3 a: R=Ph; 2 b, 3 b: R=COOCH3 ; 2 c, 3 c: R=p-CH3 -C6 H4 ; L=C7 H4 NS2 ) through hydroboration reaction. Ruthenium and the HBCC unit of the vinylborane moiety in 2 a-c are linked by a unique η(4) -interaction. Conversions of 1 into 3 a-c proceed through the formation of intermediates 2 a-c.

Phase 2 trial of everolimus and carboplatin combination in patients with triple negative metastatic breast cancer.

Introduction: Rapamycin acts synergistically with platinum agents to induce apoptosis and inhibit proliferation in breast cancer cell lines. Combination of everolimus also known as RAD001 (oral mammalian target of rapamycin (mTOR) inhibitor) and carboplatin may have activity in metastatic triple-negative breast cancer (TNBC).

Methods: The primary objective of this study was to determine clinical benefit rate (CBR), that is (complete remission (CR) + partial remission (PR) + stable disease (SD) lasting ≥6 months) and the toxicity of everolimus/carboplatin in women with metastatic TNBC.

Exploring the experiences of violence among individuals who are homeless using a consumer-led approach.

Homelessness increases vulnerability to violence victimization; however, the precise factors associated with victimization and injury are not clearly understood. Thus, this study explores the prevalence of and characteristics associated with violence victimization among homeless individuals by surveying approximately 500 individuals experiencing homelessness in 5 cities across the United States. Our findings reveal that nearly one-half of our sample reported experiencing violence and that prolonged duration of homelessness (greater than 2 years) and being older increased the risk of experiencing a violent attack.

A phase 2 study of oxaliplatin combined with continuous infusion topotecan for patients with previously treated ovarian cancer.

Background: Phase 2 trials suggest that prolonged intravenous (IV) infusion of the topoisomerase 1 inhibitor topotecan may be less toxic than when given by standard IV bolus 5-day administration. Oxaliplatin exhibits efficacy in platinum-pretreated disease and shows preclinical synergy with topoisomerase 1 inhibitors. We sought to determine the efficacy and safety of oxaliplatin plus infusion topotecan in recurrent platinum-pretreated ovarian cancer.
