Influence of intrapartum maternal fluids on weight loss in breastfed newborns

Abstract Objective The main purpose of our study has been to establish a link between the administration of intravenous fluids during Labor and the weight loss experienced by infants during hospitalization. Methods We conducted a retrospective observational study using a descriptive and comparative method. We studied 150 records of patients who gave birth at term (low-risk pregnancy) of a single healthy new born with breastfeeding in a university hospital center between 1 January 2016 and 31 July 2016. Maternal, obstetrical and neonatal characteristics were registered to determine the influence of vascular filling by univariate and multivariate analysis and identified factors that may lead to increase neonatal weight loss. Results One hundred and fifty mother–child couples were studied. Newborns whom mothers received at least 1500 mL of solute during Labor lose significantly more weight until the third day of life (p < .001) compared to women who received less than 1500 mL, also observed for neonatal weight loss greater than 8% (p = .043). In addition, the obstetrical factors most significantly associated with an increase in the volume of solute injected were the duration of Labor (p < .001), the administration of oxytocin (p < .001), epidural analgesia (p = .01) and emergency cesarean section during Labor (p < .001). Conclusion We found a link between vascular volume injected during Labor and increased risk of neonatal weight loss. Taking this factor into account when monitoring Labor in the birth room is essential to prevent and adapt neonatal management in the event of excessive weight loss.

Characteristics and Health Status of Informal Unpaid Caregivers — 44 States, District of Columbia, and Puerto Rico, 2015–2017

In 2015, an estimated 17.7 million U.S. persons were informal caregivers who provided substantial services through in-home, unpaid assistance to their family members and friends (1). Caregiving can have many benefits, such as enhancing the bond between caregiver and recipient, but it can also place an emotional and physical strain on caregivers, leading to higher rates of depression, lower quality of life, and poorer overall health (2). As the U.S. population continues to age (3), the need for informal caregivers will likely increase. However, little nationally representative information on prevalence of caregivers is available. This study examined demographic characteristics and health status of informal caregivers from 44 states,* the District of Columbia (DC), and Puerto Rico, based on data from the Behavioral Risk Factor Surveillance System (BRFSS) collected during 2015-2017. Overall, approximately one in five adults reported that they had provided care to a family member or friend in the preceding 30 days. Fifty-eight percent of caregivers were women, and a majority were non-Hispanic white, with at least some college education, and married or living with a partner. Across all states, 19.2% of caregivers reported being in fair or poor health, although significant state-to-state variation occurred. Caregivers provide important support to family members, friends, and the health care system and might compromise their own health to provide this support (1,2). Better understanding of caregivers and the challenges they face could inform implementation of improvements in support systems that could enhance not only the health of the caregiver, but that of the care recipient as well. For example, additional data regarding demographics at the state level might aid in more effective planning and support of caregivers with evidence-based programs and assistance (https://www.cdc.gov/aging/publications/features/caring-for-yourself.html).
Atorvastatin inhibits renal inflammatory response induced by calcium oxalate crystals via inhibiting the activation of TLR4/NF‐κB and NLRP3 inflammasome

This study aimed to investigate the renal protective effect of atorvastatin (ATV) on the kidney inflammation induced by calcium oxalate (CaOx) crystals. A cell model of cell‐crystal interactions and a rat model of CaOx kidney stone were established. The expressions of TLR4, NF‐κB, NLRP3, and cleaved caspase‐1 in cells and rat kidney tissues were detected using Western blot, immunohistochemical, and/or immunofluorescence. The concentrations of malondialdehyde (MDA), superoxide dismutase (SOD), reactive oxygen species (ROS) in cells, and lactic acid dehydrogenase (LDH) in the culture medium were measured. The secreted levels of interleukin (IL)‐1β, IL‐18, IL‐6, and tumor necrosis factor‐α (TNF‐α) were examined by ELISA. The serum levels of creatinine (CRE) and blood urea nitrogen (BUN) were measured. von Kossa staining was used for the evaluation of renal lens deposition. The CaOx model group showed significantly decreased SOD level; increased concentrations of MDA; ROS and LDH; elevated expressions of TLR4, NF‐κB, NLRP3, and cleaved caspase‐1; and the elevated release of IL‐1β, IL‐18, IL‐6, and TNF‐ α as compared to the control group. The treatment with ATV significantly inhibited the formation of CaOx kidney stone by increasing the level of SOD; downregulating MDA, ROS, and LDH; inhibiting the expressions of TLR4, NF‐κB, NLRP3 and cleaved caspase‐1; and blocking the secretion of inflammatory cytokines. In addition, the serum levels of CRE and BUN, and the intrarenal crystal deposition were also significantly decreased in ATV‐treated rats. In summary, oxidative stress, TLR4/NF‐κB, and NLRP3 inflammasome pathways are involved in renal inflammatory responses induced by CaOx crystals. ATV treatment significantly suppressed oxidative stress, inhibited the activation of TLR4/NF‐κB and NLRP3 inflammasome pathways, and decreased the release of inflammatory mediators, thereby ameliorating CaOx crystal‐induced damage and crystal deposition in HK‐2 cells and rat kidney tissues.
Recent Advances in TiO2-Based Photocatalysts for Reduction of CO2 to Fuels

Titanium dioxide (TiO2) has attracted increasing attention as a candidate for the photocatalytic reduction of carbon dioxide (CO2) to convert anthropogenic CO2 gas into fuels combined with storage of intermittent and renewable solar energy in forms of chemical bonds for closing the carbon cycle. However, pristine TiO2 possesses a large band gap (3.2 eV), fast recombination of electrons and holes, and low selectivity for the photoreduction of CO2. Recently, considerable progress has been made in the improvement of the performance of TiO2 photocatalysts for CO2 reduction. In this review, we first discuss the fundamentals of and challenges in CO2 photoreduction on TiO2-based catalysts. Next, the recently emerging progress and advances in TiO2 nanostructured and hybrid materials for overcoming the mentioned obstacles to achieve high light-harvesting capability, improved adsorption and activation of CO2, excellent photocatalytic activity, the ability to impede the recombination of electrons-holes pairs, and efficient suppression of hydrogen evolution are discussed. In addition, approaches and strategies for improvements in TiO2-based photocatalysts and their working mechanisms are thoroughly summarized and analyzed. Lastly, the current challenges and prospects of CO2 photocatalytic reactions on TiO2-based catalysts are also presented.
Evaluation of Hand Tendon Movement by Using High-Frequency Ultrasound Vector Doppler Imaging

Objective: Injuries to the hands, wrists, and fingers often involve damage to the tendons. The ability to measure tendon movements during the rehabilitation process can provide clinicians with important information in the quantification of tendon injuries. Conventionally, the tendon is considered a single spring-like structure during force transmission, and its twisted structure is neglected. Recently, clinicians believed that the twisted fiber structure (which enables tendon rotation during movement) of the tendon can provide it with a degree of elasticity and improve the efficiency of force transmission. However, observation of the hand tendon rotation in vivo by using the current imaging modalities is difficult. Methods: In this study, a 40-MHz high-frequency vector Doppler imaging (HFVDI) was used to visualize the movement of the hand tendon during muscle contraction. The performance of HFVDI was verified using a rotation phantom experiment. Two human experiments were designed in the present study: 1) participants were allowed to bend their distal and proximal interphalangeal (DIP and PIP) joints of fingers freely and 2) the PIP joint of the finger was fixed such that only the DIP could be moved. The HFVDIs of the flexor digitorum superficialis (FDS) and flexor digitorum profundus (FDP) tendons were obtained in the transverse and longitudinal views to observe the movements of the hand tendon during finger movements. Results: The average longitudinal displacements of the FDS and FDP were approximately 3–4 mm for free bending of the finger; however, it was reduced when only the DIP was moved. The rotational phenomenon of the FDS and FDP tendons was observed in the transverse view, which demonstrated the different rotational behaviors of the FDS and FDP fibers during muscle contraction. Conclusion: All the results validated the potential of HFVDI as a novel tool for visualizing tendon rotation and would be useful in providing quantitative information regarding tendon function to determine the rehabilitation process following injuries.
Early Psychological and Social Factors Explain the Recovery Trajectory After Distal Radial Fracture.

BACKGROUND This prospective study identified the association of demographic, injury, psychological, and social variables, measured early during recovery, with limitations in function (measured by the Patient-Reported Outcomes Measurement Information System Upper Extremity Physical Function Computer Adaptive Test [PROMIS UE]) at 6 to 9 months after a distal radial fracture. Additionally, we assessed variables associated with the PROMIS UE; the abbreviated version of the Disabilities of the Arm, Shoulder and Hand questionnaire (QuickDASH); the Patient-Rated Wrist Evaluation (PRWE); and the 3-Level EuroQol 5 Dimensions Index (EQ-5D-3L) over time. METHODS A total of 364 adult patients (73% female), with a median age of 65 years (interquartile range, 45.5 to 77 years), who sustained an isolated distal radial fracture completed questionnaires at 3 time periods after the fracture: within 1 week, between 2 and 4 weeks, and between 6 and 9 months. We created a multivariable regression model and a generalized least squares random effects model, accounting for multicollinearity using correlation matrices, the variable inflation factor, and the partial R. RESULTS Multiple variables within a week of the injury correlated with 6 to 9-month limitations in bivariate analysis. Being retired (partial R = 0.19; p < 0.001), using opioids after the fracture (partial R = 0.04; p < 0.001), using antidepressants (partial R = 0.11; p < 0.001), greater pain interference (partial R = 0.03; p = 0.001), and greater pain catastrophization (partial R = 0.04; p = 0.002) within 1 week of the injury were strong predictors of greater limitations (PROMIS UE) at 6 to 9 months in multivariable analysis. Longitudinal analysis of variables over time demonstrated greater pain interference, greater fear of movement, lower self-efficacy, older age, and female sex as strong predictors of limitations. CONCLUSIONS Recovery from a distal radial fracture is influenced by a series of demographic, psychological, and social variables. Of these factors, being retired, using opioids, using antidepressants, greater pain interference, and greater pain catastrophization within a week of the injury explain the largest amounts of unique variance in self-perceived upper-extremity physical function. Evaluating the impact of change in variables over time underlined the influence of pain interference as well as the influence of fear of movement and self-efficacy (or resiliency) on limitations in physical function and general health. These findings have important implications for identifying individuals who can benefit from behavioral interventions for these psychological factors to optimize recovery.

Exon-4 Mutations in KRAS Affect MEK/ERK and PI3K/AKT Signaling in Human Multiple Myeloma Cell Lines

Approximately 20% of multiple myeloma (MM) cases harbor a point mutation in KRAS. However, there is still no final consent on whether KRAS-mutations are associated with disease outcome. Specifically, no data exist on whether KRAS-mutations have an impact on survival of MM patients at diagnosis in the era of novel agents. Direct blockade of KRAS for therapeutic purposes is mostly impossible, but recently a mutation-specific covalent inhibitor targeting KRASp.G12C entered into clinical trials. However, other KRAS hotspot-mutations exist in MM patients, including the less common exon-4 mutations. For the current study, the coding regions of KRAS were deep-sequenced in 80 newly diagnosed MM patients, uniformely treated with three cycles of bortezomib plus dexamethasone and cyclophosphamide (VCD)-induction, followed by high-dose chemotherapy and autologous stem cell transplantation. Moreover, the functional impact of KRASp.G12A and the exon-4 mutations p.A146T and p.A146V on different survival pathways was investigated. Specifically, KRASWT, KRASp.G12A, KRASp.A146T, and KRASp.A146V were overexpressed in HEK293 cells and the KRASWT MM cell lines JJN3 and OPM2 using lentiviral transduction and the Sleeping Beauty vector system. Even though KRAS-mutations were not correlated with survival, all KRAS-mutants were found capable of potentially activating MEK/ERK- and sustaining PI3K/AKT-signaling in MM cells.
Atrial fibrillation in the elderly general population: a 30-year follow-up from 70 to 100 years of age

Abstract Objectives. There is limited knowledge of atrial fibrillation (AF) incidence among the very old. Data from longitudinal cohort studies may give us a better insight. The aim of the study was to investigate the incidence rate and prevalence of AF, as well as the impact of AF on mortality, in the general population, from 70 to 100 years of age. Design. This was a population-based prospective cohort study where three representative samples of 70-year-old men and women (n = 2,629) from the Gerontological and Geriatric Populations Studies in Gothenburg (H-70) were included between 1971 and 1982. The participants were examined at age 70 years and were re-examined repeatedly until 100 years of age. AF was diagnosed according to a 12-lead electrocardiogram (ECG) recording at baseline and follow-up examinations, from the Swedish National Patient Register (NPR), or from the Cause of Death Register. Results. The cumulative incidence of AF from 70 to 100 years of age was 65.6% for men and 52.8% for women. Mortality was significantly higher in participants with AF compared with those without, rate ratio (RR) 1.92 (95% CI 1.73–2.14). In a subgroup analysis comprising only participants with AF diagnosed by ECG at screening, the RR for death was 1.29 (95% C.I: 1.03–1.63). Conclusions. Among persons surviving to age 70, the cumulative incidence of AF was over 50% during follow-up. Mortality rate was twice as high in participants with AF compared to participants without AF. Among participants with AF first recorded at a screening examination, the increased risk was only 29%.
Aspiration and Voice Onset Time in Word‐Initial Consonant Clusters in English

A list of 224 English words beginning with prestressed consonant clusters or single consonants was recorded in the frame “Say … instead” by three talkers. The timing of glottal gestures relative to supraglottal events was studied by spectrographic analysis of the data. Voice onset time (VOT) defined in this case by the onset of visible voicing striations in the spectrogram at frequencies above the first formant (relative to stop release) was measured for all words involving plosive consonants. In voiced plosives, this interval is occupied by frication noise of about 18‐msec duration before a vowel and 25 msec before a sonorant consonant. In voiceless plosives, the frication noise burst is followed by an interval of aspiration noise. The sum of these two noise intervals, i.e., the VOT, was about 60 msec preceding vowels and 75 msec preceding sonorant consonants. If a voiceless plosive was preceded by [s], the VOT was much less, i.e., about 5 msec greater than the data for the analogous voiced plosive. The .
Resolving anticipatory grief and enhancing dignity at the end-of life: A systematic review of palliative interventions

Abstract Anticipatory grief is the experience of grief symptomatology prior to loss. This study is a systematic review of empirical interventions or interventional components that were observed to lessen or adaptively direct the experience of anticipatory grief for patients at the end of life and their family members. A search of 5 major databases found 13,718 articles, of which 10 high-quality randomized controlled trials were included for final review. Lebow’s “adaptational tasks of anticipatory mourning” was employed as a working model on the efficacy of the interventions. The interventions exhibited some positive outcomes but none addressed anticipatory grief directly. Recommendations for future research are discussed.
Risk for physical dependence in community-dwelling older adults: The role of fear of falling, falls and fall-related injuries.

BACKGROUND Falls and fall-related injuries along with fear of falling (FoF) seem to restrict activities of daily living (ADL), resulting in physical dependence. However, it is still unclear how falls and related injuries or FoF by themselves explain general and specific ADL dependence. OBJECTIVES To investigate the relationships between falls and related injuries, FoF and physical dependence on ADL in community-dwelling older adults, controlling for age, gender, physical activity and physical fitness as confounders. METHODS This cross-sectional descriptive study assessed 588 community-dwelling older adults. Falls and fall-related injuries, ADL dependence on basic, instrumental and advanced activities, FoF, demographic characteristics and health conditions were assessed through a questionnaire. Physical activity was measured through the International Physical Activity Questionnaire. Physical fitness was assessed by the Senior Fitness Test and the Fullerton Advanced Balance Scale. Body composition was measured through bioimpedance. RESULTS Severe injuries occurrence increased the likelihood of moderate and high physical dependence by 3 and 6 times, while FoF increased this likelihood by 3 and 7 times, respectively. Also, the occurrence of previous falls, resulting in severe injuries, increased the likelihood of dependence in two instrumental ADL (3 and 4 times), while FoF increased this likelihood in numerous basic, instrumental and advanced ADL (2-3 times). The FoF was shown to explain overall physical functioning dependence, by itself, representing a constraint on the performance of most basic, instrumental and advanced ADL. CONCLUSION The FoF showed to be a greater threat to ADL dependence than falls and related injuries. Assessment guidelines for older adults living in the community should include the FoF in clinical evaluation. IMPLICATIONS FOR PRACTICE Understand the isolated interplay of FoF and previous falls and injuries on ADL dependence among older adults allows healthcare professionals to perform more accurate clinical evaluations and develop more successful interventions to prevent further dependence.
Functional MgO–Lignin Hybrids and Their Application as Fillers for Polypropylene Composites

Inorganic–organic hybrids are a group of materials that have recently become the subject of intense scientific research. They exhibit some of the specific properties of both highly durable inorganic materials (e.g., titanium dioxide, zinc) and organic products with divergent physicochemical traits (e.g., lignin, chitin). This combination results in improved physicochemical, thermal or mechanical properties. Hybrids with defined characteristics can be used as fillers for polymer composites. In this study, three types of filler with different MgO/lignin ratio were used as fillers for polypropylene (PP). The effectiveness of MgO-lignin binding was confirmed using Fourier transform infrared spectroscopy. The fillers were also tested in terms of thermal stability, dispersive-morphological properties as well as porous structure. Polymer composites containing 3 wt. % of each filler were subjected to wide angle X-ray diffraction tests, differential scanning calorimetry and microscopic studies to define their structure, morphology and thermal properties. Additionally, tensile tests of the composites were performed. It was established that the composition of the filler has a significant influence on the crystallization of polypropylene—either spherulites or transcrystalline layers were formed. The value of Young’s modulus and tensile strength remained unaffected by filler type. However, composites with hybrid fillers exhibited lower elongation at break than unfilled polypropylene.
Latent composite indicators for evaluating adherence to guidelines in patients with a colorectal cancer diagnosis

Supplemental Digital Content is available in the text Abstract Evidence-based guidelines for the correct management of cancer patients are developed on the idea that timely care can improve health prognoses and quality of life. The aim of this paper is to evaluate the adherence of clinical pathways to clinical guidelines provided at the hospital level, for colorectal cancer care. By using a retrospective observational study, we proposed a method for associating each patient to a healthcare provider and modeling adherence as a latent construct governed by a set of 10 influential indicators. These indicators measure the adherence to specific guidelines for diagnosis, surgical treatment, chemotherapy, and follow-up. The model used was that of the item response theory (IRT). When evaluating providers, the IRT allows for a comparison of indicators in terms of their discriminating ability and difficulty, and in terms of their adherence to guidelines. The IRT results were compared with non-latent methods: numerator-based weight and denominator-based weight. A strong degree of coherence of the indicators in measuring adherence, and a high level of overall agreement between latent and non-latent methods were noted. The IRT approach demonstrated similar providers’ evaluations between endoscopy and histological assessment indicators. The greatest discriminating ability among providers could be attributed to all diagnostic exams, while the lowest was associated with follow-up endoscopies. The most difficult indicator to achieve was fecal occult blood test, while follow-up imaging was the easiest. In a decision-making framework, valuable indications can be derived from the use of IRT models rather than weighting methods. Using IRTs, we were able to highlight the principal indicators in terms of strength of discrimination, and to isolate those that merely duplicated information.
