Published: September 2023

Os materiais resinosos vem ganhando destaque na odontologia minimamente invasiva, bem como mostraram-se um ótimo aliado na biocompatibilidade, adesão e resistência mecânica. A longevidade das restaurações em resina composta depende de fatores que envolvem o cirurgião-dentista, o paciente, além da técnica utilizada. As motivações que interferem no sucesso desses procedimentos são discutidas em diversos estudos, sendo os dentes posteriores apontados como os principais elementos envolvidos em falhas. Assim, o presente trabalho teve o objetivo de realizar uma revisão bibliográfica do tipo narrativa, com abordagem documental e observacional, voltada para os fatores que contribuem para as falhas na longevidade de restaurações em resinas compostas de dentes posteriores. Nessa revisão, buscaram-se artigos disponíveis para a leitura, acerca do tema e publicados entre os anos de 2005 até 2023. Durante a busca, avaliaram-se causas de insucesso dos procedimentos restauradores, dentre as quais foram apontadas em comum: cárie secundária; fratura; hábitos parafuncionais e desordens oclusais; características da cavidade; técnica operatória e material restaurador; nível socioeconômico do paciente. Cárie secundária e fraturas foram relatados como os fatores predominantes para falhas de restaurações em dentes posteriores.

Authors: Kell C M , Haffejee F , Ducray J F 
Published: October 2023

Background. Engagement between higher education institutions and underprivileged communities holds valuable potential for mutual benefit. In a country of vast inequalities such as South Africa (SA), community engagement also has the potential, via health promotion of local communities, to alleviate some of the burden placed on the public healthcare system, while simultaneously strengthening the personal and professional development of student participants.
Objective. To explore the experiences, perceptions and insights of student volunteers (SVs) who assisted with a collaborative health-promotion project. Methods. This qualitative study used thematic analysis of semi-structured interviews to explore the experiences of six SVs in the Faculty of Health Sciences, Durban University of Technology, SA, who assisted in educating local vulnerable women on various aspects of female reproductive health at a wellness day for such women.
Results. The SVs described the experience as positive and humbling, enhancing their professional and personal development. They reported that the community engagement helped them to define themselves and to grow skills they will need as future practitioners. The exposure to the challenges faced by vulnerable groups helped them to develop a sense of empathy and compassion, while igniting an eagerness to empower these groups through improved health literacy.
Conclusion. The insights provided by this qualitative exploration strongly support the use of community engagement to develop culturally sensitive, empathetic healthcare practitioners.

ImportanceVenous thromboembolism (VTE) represents a major source of preventable morbidity and mortality and is a leading cause of death in the US after cancer surgery. Previous research demonstrated variability in VTE chemoprophylaxis prescribing, although it is unknown how these rates compare with performance in the Veterans Health Administration (VHA).ObjectiveTo determine VTE rates after cancer surgery, as well as rates of inpatient and outpatient (posthospital discharge) chemoprophylaxis adherence within the VHA.Design, Setting, and ParticipantsThis retrospective cohort study within 101 hospitals of the VHA health system included patients aged 41 years or older without preexisting bleeding disorders or anticoagulation usage who underwent surgical treatment for cancer with general surgery, thoracic surgery, or urology between January 1, 2015, and December 31, 2022. The VHA Corporate Data Warehouse, Pharmacy Benefits Management database, and the Veterans Affairs Surgical Quality Improvement Program database were used to identify eligible patients. Data analysis was conducted between January 2022 and July 2023.ExposuresInpatient surgery for cancer with general surgery, thoracic surgery, or urology.Main Outcomes and MeasuresRates of postoperative VTE events within 30 days of surgery and VTE chemoprophylaxis adherence were determined. Multivariable Poisson regression was used to determine incidence-rate ratios of inpatient and postdischarge chemoprophylaxis adherence by surgical specialty.ResultsOverall, 30 039 veterans (median [IQR] age, 67 [62-71] years; 29 386 men [97.8%]; 7771 African American or Black patients [25.9%]) who underwent surgery for cancer and were at highest risk for VTE were included. The overall postoperative VTE rate was 1.3% (385 patients) with 199 patients (0.7%) receiving a diagnosis during inpatient hospitalization and 186 patients (0.6%) receiving a diagnosis postdischarge. Inpatient chemoprophylaxis was ordered for 24 139 patients (80.4%). Inpatient chemoprophylaxis ordering rates were highest for patients who underwent procedures with general surgery (10 102 of 10 301 patients [98.1%]) and lowest for patients who underwent procedures with urology (11 471 of 17 089 patients [67.1%]). Overall, 3142 patients (10.5%) received postdischarge chemoprophylaxis, with notable variation by specialty.Conclusions and RelevanceThese findings indicate the overall VTE rate after cancer surgery within the VHA is low, VHA inpatient chemoprophylaxis rates are high, and postdischarge VTE chemoprophylaxis prescribing is similar to that of non-VHA health systems. Specialty and procedure variation exists for chemoprophylaxis and may be justified given the low risks of overall and postdischarge VTE.

AbstractSystemic sclerosis (SSc) is an immune‐mediated rheumatic disease that is characterized by fibrosis of the skin and internal organs and vasculopathy with poor prognosis. Dangui Huoxue Preparation (DHP) is a clinically effective traditional Chinese herbal formula for the treatment of SSc in the hospital. This study aims to investigate the therapeutic effects and underlying molecular mechanisms of DHP in the treatment of SSc. SSc mice models are induced by bleomycin (BLM). Tissues of DHP group, normal control group, and positive control drug Sanqi Tongshu Capsule (STC) group are collected for inflammation, fibrosis, and vasculopathy. Also, the human dermal fibroblasts (HDF) stimulated with TGF‐β1 are analyzed for in vitro study. The expression levels of MCP‐1, IFN‐γ, IL‐1β, IL‐10, Fizz1, iNOS, and IL12p40, and the mRNA levels of Col1a1, Col1a2, Col3a1, and Col5a1 are significantly decreased in all DHP groups and STC group compare with those in the BLM group. The main drug of DHP inhibits the proliferation and migration of HDF, reduces Ctgf, Itgb3, Itgb5 expression, and also inhibits the Smad3 pathway. In conclusion, DHP can ameliorate SSc skin inflammation, fibrosis, and vasculopathy, possibly suppressing the TGF‐β1/Smad3 signaling pathway through extracellular and intracellular mechanisms.

AbstractAs an emerging earth‐abundant light harvesting material, antimony selenosulfide (Sb2(S,Se)3) has received tremendous attention for photovoltaics. Manipulating the carrier separation and recombination processes is critical to achieve high device efficiency. Compared to the conventional planar heterojunction (PHJ), the bulk heterojunction (BHJ) configuration affords great potential to enable efficient charge extraction. In this work, BHJ Sb2(S,Se)3 solar cells are constructed based on CdS nanorod arrays (NRAs). Highly ordered CdS NRAs with appropriate nanorod lengths and diameters are obtained by regulating the growth environment and screening different substrates for CdS deposition. A low‐temperature oxygen doping strategy implemented on CdS NRAs is further developed to improve the optoelectronic and defect properties as well as form a favorable cascade band structure for CdS NRAs, so as to realize more efficient charge extraction and suppressed recombination at the heterointerface. As a result, the CdS NRAs‐based superstrated BHJ Sb2(S,Se)3 solar cell yields a considerable power conversion efficiency of 8.04%, outperforming that of the PHJ device. A careful comparative study of PHJ and BHJ based on electrostatic field simulations indicates that the BHJ allows more efficient charge extraction and transport. This work highlights the great potential of BHJ configuration for constructing high‐performance antimony chalcogenide solar cells.

AbstractIntroducing the guest materials into binary active layer to construct ternary organic solar cells (OSCs) is widely used to improve device performance. Nevertheless, designing the guest materials is a challenging task. Herein, asymmetric alloy acceptor strategy guided by similarity principle to design the guest materials is employed. Two small molecular acceptors (ZH1 with symmetric end groups and ZH2 with asymmetric end groups) with the same skeleton to the host acceptor are synthesized and compared. Compared to symmetric ZH1, asymmetric ZH2 delivers a remarkably higher efficiency (3.86% vs 13.03%) when paired with PM6, benefiting from the larger dipole moment to facilitate charge dynamics and more favorable morphology. More importantly, by introducing ZH1 and ZH2 as the guest materials into the PM6:BTP‐eC9 blend, both ZH1 and ZH2 well alloy with acceptor BTP‐eC9 due to the similar skeleton, not only providing a complementary absorption, but also optimizing and stabilizing the blend morphology. Notably, the asymmetric alloy acceptor distinctly outperforms symmetric alloy acceptor, PM6:BTP‐eC9:ZH2‐based device achieves an outstanding efficiency of 18.75% with better stability and reduced non‐radiative energy loss. Therefore, developing asymmetric alloy acceptor is an effective strategy to develop high‐performance and stable OSCs.
Dispersion Engineering by Hybridizing the Back‐Folded Soft Mode of Monomode Elastic Metamaterials with Stiff Acoustic Modes

Published: September 2023

AbstractIn many cases, the hybridization of two or more excitation modes in solids has led to new and useful dispersion relations of waves. Well‐studied examples are phonon polaritons, plasmon polaritons, particle‐plasmon polaritons, cavity polaritons, and magnetic resonances at optical frequencies. In all of these cases, the lowest propagating mode couples to a finite‐frequency localized resonance. Herein, the unusual metamaterial phonon dispersion relations arising from the hybridization of an ordinary acoustical phonon mode with a back‐folded soft or easy phonon mode of a monomode elastic metamaterial are discussed. Conceptually, the single easy mode can have strictly zero wave velocity. In reality, its wave velocity is very much smaller than that of all other modes. Considering polymeric three‐dimensional printed elastic monomode metamaterials at ultrasound frequencies, it is shown theoretically and experimentally that the resulting pronounced avoided crossing, with a frequency splitting comparable to the mid‐frequency, leads to backward‐wave behavior for the lowest band over a broad frequency range, conceptually at zero loss.

Published: September 2023

AbstractSemiconducting polymer chains constitute the building blocks for a wide range of electronic materials and devices. However, most of their electrical characteristics at the single‐molecule level have received little attention. Elucidating these properties can help understanding performance limits and enable new applications. Here, coupled ionic–electronic charge transport is exploited to measure the quasi‐1D electrical current through long single conjugated polymer chains as they form transient contacts with electrodes separated by ≈10 nm. Fluctuations between internal conformations of the individual polymers are resolved as abrupt, multilevel switches in the electrical current. This behavior is consistent with the theoretical simulations based on the worm‐like‐chain (WLC) model for semiflexible polymers. In addition to probing the intrinsic properties of single semiconducting polymer chains, the results provide an unprecedented window into the dynamics of random‐coil polymers and enable the use of semiconducting polymers as electrical labels for single‐molecule (bio)sensing assays.

AbstractRecent advances reveal that due to the cross‐relaxation restriction, impressive upconversion (UC) enhancement (≈100‐folds) can be achieved in cryogenic Er3+‐rich core‐inert shell nanostructures (e.g., NaErF4@NaYF4), which opens up exciting opportunities in diverse frontier applications. However, further promotion of UC intensity is still highly desired, in which the rational design of nanostructures can play a key role. Herein, it is demonstrated that adopting an active shell design will constantly benefit the UC within a wide temperature range (40–300 K). Specifically, through constructing the luminescent core@active shell@inert shell sandwich nanostructure (e.g., NaErF4@NaYbF4@NaYF4), 8.3–73‐folds UC enhancement will be achieved (taking the corresponding core@inert shell structures as competitors). Moreover, from spectral‐domain and time‐domain spectroscopic experiments, the relevant UC enhancement is convincingly attributed to a temperature‐dependent energy injection process (from the active shell to the luminescent core). More interestingly, the unique property of the material makes a temperature‐induced high‐level encryption application possible, which is obtained by employing the nanomaterials on a quick response (QR) code. These results not only deepen the UC mechanism in multi‐layer nanostructures, but also introduce an expanded dimension (via low temperatures) in information security.
Effects of household composition on infant feeding and mother–infant health in northern Kenya

Published: September 2023

AbstractBackgroundHouseholds with alloparents, individuals other than the mother who care for an infant, can shift members' roles and affect mother–infant health.AimsTo investigate how household composition relates to infant feeding and infectious disease risk in mother–infant dyads, the team utilized data from breastfeeding dyads (n 208) surveyed during a prolonged drought and food scarcity in northern Kenya.MethodsHouseholds were classified by the presence/absence of potential alloparents, distinguishing non‐siblings and siblings of the infant. Regression models for breastfeeding frequency, complementary feeding status, and recent infections (n 83) evaluated these outcomes' associations with household type while accounting for food insecurity, adjusted for infant age, infant sex, and maternal age.ResultsHousehold type was unassociated with breastfeeding frequency, but the presence of non‐sibling alloparents interacted with food insecurity, predicting increasing breastfeeding frequency as food insecurity intensified among dyads living with non‐sibling alloparents. Households with non‐sibling alloparents were also inversely associated with complementary feeding but had no association with infection. Households with siblings were inversely associated with (protective against) infant and maternal infection.ConclusionFurther research is needed to understand the interactive influence of household social and food ecologies on mother–infant diet and health under diverse cultural rules and norms for alloparenting.
