Recovery post Total Knee Replacement Surgery ((TKA) has been a subject of interest. In a study of 379 patients who had hip or knee replacement surgery, it was reported that at 6 months post-surgery patients with better baseline function had superior functional ability and less pain than patients with lower function at baseline. Another study of 276 patients undergoing TKA reported that pre-operative joint function was a predictor of joint function and overall function at 6 months post-surgery. These findings suggest that prehabilitation to increase functional ability prior to TKA may have a positive effect in recovering post-surgery. In a randomized control trial of patients receiving TKA, the group receiving an Exercise Program (prehabilitation) made significant improvements in performance from baseline to before surgery, and at 1 and 3 months post surgery. For the group that did not receive the Exercise Program pre-surgery, significant improvement did not occur until 3 months post surgery. The overall objective of the proposed single-blinded randomized controlled trial is to demonstrate that a well designed prehabilitation program for patients receiving TKA surgery will significantly improve outcomes related to pain and function and may reduce utilization of health care services post surgery.

In this randomized control trial we hypothesize that the group of participants who receive a prehabilitation Exercise Program will recover quicker than patients who do not receive the Exercise Program based on several measures of performance including pain, quadriceps strength, range of motion and quality of life.
Individuals who are newly diagnosed with HIV often experience a variety of social and psychological problems, which can leave them depressed and unable to cope with their disease. The complex financial, legal, and psychiatric issues that many HIV-infected individuals must face can be stressful and can negatively affect their health; they may miss doctors' appointments or fail to adhere to a strict HIV medication regimen. The combination of stress and inconsistent medical care can affect the immune system and potentially worsen HIV symptoms.

Because of the multitude of stressors associated with HIV, HIV-infected individuals often rely on a network of family and friends for support; these caregivers, however, are often overwhelmed by their caregiver roles. They may experience helplessness, fear, and depression as a result of their added responsibilities. Family Intervention: Telephone Tracking (FITT) is a telephone-based intervention program that assists in identifying problems and resolving them through referrals to medical and community organizations that provide HIV-related support and services. It is also an educational resource that provides information on the many medical and psychological aspects of HIV infection. The main goal of FITT is to alleviate stress in both the HIV-infected individual and their support network by providing information and resources to help cope with HIV. The purpose of this study is to evaluate the effectiveness of FITT in improving family functioning, enhancing coping skills, and reducing depression in HIV-infected individuals and their caregivers.

This 12-month study will enroll recently diagnosed HIV-infected individuals and one family member or friend who is identified as their primary caregiver. Each pair will be randomly assigned to either the FITT intervention group or to an assessment-only group that will not receive FITT. Individuals who are assigned to receive FITT will utilize the service for Months 1 through 6. HIV-infected participants in both groups will also receive regular medical care throughout the study. Outcome measurements will include self-assessments of depression, coping, and family functioning. In addition, participants receiving FITT will be asked to evaluate the effectiveness of the telephone intervention. All measurements will be assessed at baseline, and Months 3, 6, and 12.
Following myocardial infarction (MI), adverse remodeling depends on the proper formation of fibrotic scars, composed of type I and III collagen. Our objective was to pinpoint the participation of previously unreported collagens in post-infarction cardiac fibrosis. Gene (qRT-PCR) and protein (immunohistochemistry followed by morphometric analysis) expression of fibrillar (types II and XI) and non-fibrillar (types VIII and XII) collagens were determined in RNA-sequencing data from 92 mice undergoing myocardial ischemia; mice submitted to permanent (non-reperfused MI, n = 8) or transient (reperfused MI, n = 8) coronary occlusion; and eight autopsies from chronic MI patients. In the RNA-sequencing analysis of mice undergoing myocardial ischemia, increased transcriptomic expression of collagen types II, VIII, XI, and XII was reported within the first week, a tendency that persisted 21 days afterwards. In reperfused and non-reperfused experimental MI models, their gene expression was heightened 21 days post-MI induction and positively correlated with infarct size. In chronic MI patients, immunohistochemistry analysis demonstrated their presence in fibrotic scars. Functional analysis indicated that these subunits probably confer tensile strength and ensure the cohesion of interstitial components. Our data reveal that novel collagens are present in the infarcted myocardium. These data could lay the groundwork for unraveling post-MI fibrotic scar composition, which could ultimately influence patient survivorship.
Radiofrequency ablation (RFA) is a thermal ablative procedure commonly used to treat chronic neurogenic pain by targeting peripheral nerves or dorsal root ganglion by destructing the tissue at a temperature ranging beteen 60-80 C. The pain is interrupted by destructing the nerve with Wallerian dejeneration. The pain interruption period is longer and stronger than pulsed radiofrequency. GON is a pure sensory nerve, RFA may be an alternative therapy option for occipital neuralgia. By ultrasound (US) guidance, at C2 level , GON lies between semispinalis capitis muscle and inferior oblique muscle. The GON is well identified here and can be easily targeted rather than trying to identify the terminal subcutaneous branches at the nuchal line. Diagnostic blockade was administered to patients who did not respond to conventional therapy. If the response to diagnostic blockade was greater than 50%, RFA was instituted one week later. Patients' headache intensity was measured using the Numeric Rating Scale-11 Pain Score (NRS) at each appointment (pre-intervention, 1-3-6, and 12 months post-intervention). At each appointment, an evaluation of headache disability was conducted using the Headache Impact Test (Hit-6) and the number of headache days per month. The efficacy of the treatment was defined as NRS\<4 at the twelveth month. During the initial evaluation, patients' demographic details and headache symptoms were thoroughly questioned. In accordance with the Turkish National Headache and Pain Research Association's recommendation, patients were asked to keep up headache diaries for the duration of the treatment and all subsequent appointments. The headache intensity, headache disability and the number of headache days in a month, as well as the use of rescue medication, including NSAIDs and paracethamol, were determined from the diaries and discussed with the patient at each session.
Systems and methods for managing data in compliance with regulated privacy, security, and electronic transaction standards. One or more computer devices are used in a system to manage data in compliance with regulated privacy, security, and electronic transaction standards. In one implementation, a fax machine is used to provide a transmission set to a computer system, which acknowledges receipt of the set and preserves the transmission set for a period of time to satisfy a regulation. The system includes a single point of entry for external and/or internal requests, and/or a single point of exit for transmissions of information, wherein the transmissions include individually identifiable patient information to legitimate patient-approved requests. Information is de-identified so as to be selectively used and/or sold. The de-identification prevents the identification of patients corresponding to the medical information, thus allowing the information to be useful while still preserving professional confidences. Moreover, digital authorizations and consents for retrieval from external data sources may be utilized.
Venom peptides have evolved to target a wide range of membrane proteins through diverse mechanisms of action and structures, providing promising therapeutic leads for diseases, including pain, epilepsy, and cancer, as well as unique probes of ion channel structure-function. In this work, a high-throughput FLIPR window current screening assay on T-type CaV3.2 guided the isolation of a novel peptide named ω-Buthitoxin-Hf1a from scorpion Hottentotta franzwerneri crude venom. At only 10 amino acid residues with one disulfide bond, it is not only the smallest venom peptide known to target T-type CaVs but also the smallest structured scorpion venom peptide yet discovered. Synthetic Hf1a peptides were prepared with C-terminal amidation (Hf1a-NH2) or a free C-terminus (Hf1a-OH). Electrophysiological characterization revealed Hf1a-NH2 to be a concentration-dependent partial inhibitor of CaV3.2 (IC50 = 1.18 μM) and CaV3.3 (IC50 = 0.49 μM) depolarized currents but was ineffective at CaV3.1. Hf1a-OH did not show activity against any of the three T-type subtypes. Additionally, neither form showed activity against N-type CaV2.2 or L-type calcium channels. The three-dimensional structure of Hf1a-NH2 was determined using NMR spectroscopy and used in docking studies to predict its binding site at CaV3.2 and CaV3.3. As both CaV3.2 and CaV3.3 have been implicated in peripheral pain signaling, the analgesic potential of Hf1a-NH2 was explored in vivo in a mouse model of incision-induced acute post-surgical pain. Consistent with this role, Hf1a-NH2 produced antiallodynia in both mechanical and thermal pain.
Evidence is presented that inflammation and injury involves activation of xanthine oxidoreductase (XOR) in the newly recruited mononuclear phagocytes (MNP). XOR has been shown to be increased predominantly in the MNP that increase rapidly in the lungs of rats that develop acute lung injury (ALI) following intratracheal cytokine insufflation. XOR was recovered from the MNP largely converted to its oxygen radical generating, reversible O-form, and alveolar MNP exhibited increased oxidative stress as evidenced by increased nitrotyrosine staining. Cytokine insufflation also increased alveolar cell apoptosis. A functional role for XOR in cytokine induced inflammation was demonstrated. Tungsten and allopurinol decreased MNP XOR induction, nitrotyrosine staining, inflammatory cell infiltration, and alveolar cell apoptosis. Transfer of control or allopurinol treated MNP into rat lungs and confirmed a specific role for MNP XOR in promoting lung inflammation. These data indicate that XOR can contribute to lung inflammation by its expression and conversion in a highly mobile inflammatory cell population.
The immune response varies between pigs, as not all pigs have the same response to a stressor. This variation may exist between individuals due to body weight (BW) or body composition, which may impact the capacity for coping with an immune challenge (IC). Tryptophan (Trp), threonine (Thr), and methionine (Met) requirements might also play a considerable part in supporting immune system activation while reducing variation between pigs; however, the latter has yet to be reported. This exploratory study investigated the effect of initial BW (light vs. heavy-weight) and supplementation of Trp, Thr, and Met above National Research Council (NRC) requirements on feeding behavior and the coping capacity of growing pigs under an IC. Eighty gilts were categorized into 2 groups according to BW: light-weight (LW, 22.5 kg) and heavy-weight pigs (HW, 28.5 kg). Both BW groups were group-housed for a 28-d trial in a good or poor sanitary condition (SC). Pigs within a poor SC were orally inoculated with 2 × 109 colony units of Salmonella Typhimurium, and fresh manure from a pig farm was spread on the floor. Pigs within good SC were not inoculated, nor was manure spread. Two diets were provided within each SC: control (CN) or supplemented (AA+) with Trp, Thr, and Met at 120% of NRC recommended levels. A principal component analysis was performed in R, and a feeding behavior index was calculated in SAS. Results showed that LW and HW pigs were clustered separately on day 0, where LW pigs had a positive correlation with body lipid percentage (r = 0.83), and HW pigs had a positive correlation with body protein percentage (r = 0.75). After the IC, the cluster configuration changed, with diets influencing LW more than HW pigs within poor SC. On day 14, LW fed AA + diet in poor SC was clustered separately from LW pigs fed CN diet, whereas LW fed AA + and CN diets in good SC were clustered together. For feeding behavior, in both analyzed periods (period 1: days 7 to 14; period 2: days 21 to 28), LW had lower total feed intake and shorter meals than HW pigs (P < 0.10), independent of the SC. Furthermore, LW pigs fed AA + diet had a more regular feed intake pattern than those fed CN diet, while a more irregular pattern was observed for HW pigs fed AA + diet than CN diet at period 2. These findings suggest that supplementing Trp, Thr, and Met above requirements may be a nutritional strategy for LW pigs under IC by improving feed intake regularity and reducing the probability of being susceptible to IC.
Various cancers frequently exhibit polyploidy, observed in a condition where a cell possesses more than two sets of chromosomes, which is considered a hallmark of the disease. The state of polyploidy often leads to aneuploidy, where cells possess an abnormal number or structure of chromosomes. Recent studies suggest that oncogenes contribute to aneuploidy. This finding significantly underscores its impact on cancer. Cancer cells exposed to certain chemotherapeutic drugs tend to exhibit an increased incidence of polyploidy. This occurrence is strongly associated with several challenges in cancer treatment, including metastasis, resistance to chemotherapy and the recurrence of malignant tumors. Indeed, it poses a significant hurdle to achieve complete tumor eradication and effective cancer therapy. Recently, there has been a growing interest in the field of polyploidy related to cancer for developing effective anti-cancer therapies. Polyploid cancer cells confer both advantages and disadvantages to tumor pathogenicity. This review delineates the diverse characteristics of polyploid cells, elucidates the pivotal role of polyploidy in cancer, and explores the advantages and disadvantages it imparts to cancer cells, along with the current approaches tried in lab settings to target polyploid cells. Additionally, it considers experimental strategies aimed at addressing the outstanding questions within the realm of polyploidy in relation to cancer.
The genome of living cells is constantly challenged by DNA lesions that interfere with cellular processes such as transcription and replication. A manifold of mechanisms act in concert to ensure adequate DNA repair, gene expression, and genome stability. Bulky DNA lesions, such as those induced by UV light or the DNA-damaging agent 4-nitroquinoline oxide, act as transcriptional and replicational roadblocks and thus represent a major threat to cell metabolism. When located on the transcribed strand of active genes, these lesions are handled by transcription-coupled nucleotide excision repair (TC-NER), a yet incompletely understood NER sub-pathway. Here, using a genetic screen in the yeast Saccharomyces cerevisiae, we identified histone variant H2A.Z as an important component to safeguard transcription and DNA integrity following UV irradiation. In the absence of H2A.Z, repair by TC-NER is severely impaired and RNA polymerase II clearance reduced, leading to an increase in double-strand breaks. Thus, H2A.Z is needed for proficient TC-NER and plays a major role in the maintenance of genome stability upon UV irradiation.
Improved artificial tear compositions are described. The compositions are preferably formulated as sterile, isotonic solutions. The solutions contain a unique combination of three demulcents. The solutions preferably also contain one or more electrolytes and may also contain a nonionic surfactant. The solutions provide ocular comfort and are particularly useful in patients that are experiencing mild to moderate dryness or other irritation of the cornea. The solutions may be packaged as either an unpreserved unit dose product or as a preserved multi-dose product. The multi-dose products contain a very mild antimicrobial preservative system, and consequently can be frequently applied to the eye with little risk of ocular irritation attributable to the preservative components.
INTRODUCTION: Because trauma patients in class II shock (blood loss of 15%-30% of total blood volume) arrive normotensive, this makes the identification of shock and subsequent prognostication of outcomes challenging. Our aim was to identify early predictive factors associated with worse outcomes in normotensive patients following penetrating trauma. We hypothesize that abnormalities in initial vital signs portend worse outcomes in normotensive patients following penetrating trauma.
METHODS: A retrospective review was performed from 2006 to 2021 using our trauma database and included trauma patients presenting with penetrating trauma with initial normotensive blood pressures (systolic blood pressure ≥90 mmHg). We compared those with a narrow pulse pressure (NPP ≤25% of systolic blood pressure), tachycardia (heart rate ≥100 beats per minute), and elevated shock index (SI ≥ 0.8) to those without. Outcomes included mortality, intensive care unit admission, and ventilator use. Chi-squared, Mann-Whitney tests, and regression analyses were performed as appropriate.
RESULTS: We identified 7618 patients with penetrating injuries and normotension on initial trauma bay assessment. On univariate analysis, NPP, tachycardia, and elevated SI were associated with increases in mortality compared to those without. On multivariable logistic regression, only NPP and tachycardia were independently associated with mortality. Tachycardia and an elevated SI were both independently associated with intensive care unit admission. Only an elevated SI had an independent association with ventilator requirements, while an NPP and tachycardia did not.
CONCLUSIONS: Immediate trauma bay NPP and tachycardia are independently associated with mortality and adverse outcomes and may provide an opportunity for improved prognostication in normotensive patients following penetrating trauma.
The important role of cholesterol in tumor metastasis has been widely studied in recent years. Ezetimibe is currently the only selective cholesterol uptake inhibitor on the market. Here, we explored the effect of ezetimibe on breast cancer metastasis by studying its impact on breast cancer cell migration, invasion, and epithelial-mesenchymal transition (EMT). Differential gene expression analysis and validation were also carried out to compare ezetimibe-treated and untreated breast cancer cells. Finally, breast cancer cells overexpressing TGFβ2 were constructed, and the effect of TGFβ2 on the migration and invasion of ezetimibe-treated breast cancer cells was examined. Our results show that ezetimibe treatment of breast cancer cells inhibited cell migration, invasion, and EMT, and it significantly suppressed the expression of TGFβ2. Overexpression of TGFβ2 reversed the inhibitory effect of ezetimibe on the migration and invasion of breast cancer cells. Taken together, our results suggest that ezetimibe might be a potential candidate for the treatment of breast cancer metastasis.
Systems and methods for evaluating an anatomical structure in a brain of a subject are provided. In an embodiment, a system for evaluating an anatomical structure in a brain of a subject includes a computing device in communication with a magnetic resonance imaging (MRI) device. The computing device operable to determine an abnormality in the anatomical structure by comparing a test activation level within a geometry of the anatomical structure to data in a normative database, and output, to a display device, a graphical representation of the abnormality in the anatomical structure. The test activation level is determined by aligning functional magnetic resonance imaging (fMRI) data obtained by use of the MRI device and the geometry of the anatomical structure. The geometry of the anatomical structure is delineated based on segmentation of magnetic resonance (MR) data obtained by use of the MRI device. The data in the normative database include activation levels of the anatomical structure of a plurality of neurologically non-diseased subjects.
Opportunities for sedentary leisure and physical activities will be continuously available throughout all phases. Each phase will last 20 minutes. Participants in this arm will not earn incentives during any of the three phases to control for the possibility that participants will engage in some physical activity in the absence of incentives.
Patients assigned to placebo were dosed weekly for five weeks, then at Week 8 and Week 12. At Week 16, placebo patients were randomized in a 1:1 ratio, to receive secukinumab either 150 mg or 300 mg and were dosed weekly for five weeks starting at Week 16, then once every four weeks up to and including Week 132. All doses of study treatment are administered by sub-cutaneous injections.
The VA research team has played a prominent role in documenting the significant skeletal muscle atrophy that accompanies chronic hemiparesis after disabling stroke. Muscle volume is reduced by 24% in paretic vs. non-paretic legs, having significant implications for strength, function, fitness, metabolism and general health. The investigators' previous work establishes progressive, high-intensity resistive training (RT) as an effective rehabilitation strategy for older stroke survivors, producing thigh muscle hypertrophy on both the paretic and non-paretic sides. Protein supplementation can significantly augment gains in muscle mass after RT in healthy populations, but no experiments have yet been conducted in stroke. New preliminary data from the investigators' group indicates that stroke participants consume 20% less protein than the recommended daily amount for older individuals (0.80 vs. 1.0 g/kg/day) suggesting that relative gains in skeletal muscle could be significantly better in the presence of adequate protein intake. New data also indicates that leg muscle mass predicts resting metabolic rate (RMR) in stroke, implying that a combined nutrition and RT therapy aimed at maximizing muscle gains would translate into improved energy balance, a key factor in rehabilitation success. A better understanding of the true potential for aggressive RT interventions to address stroke-related atrophy and related problems for maximum benefit awaits clinical trials directly comparing RT with and without nutritional therapy. The investigators propose to conduct a 12-week randomized placebo controlled clinical trial comparing the effects of RT+ protein supplementation at 1.2 g/kg/day (RT+PRO) vs. RT+isocaloric placebo (RT+PLA) on body composition, hypertrophy, strength, functional mobility and energy expenditure in chronic stroke.
Poor and intermediate CYP2D6 metabolizers will be randomized to either low-dose-titration condition or treatment-as-usual condition. In the treatment-as-usual condition, patients will be treated with risperidone 1mg bid for 5 days, then 2mg bid for 5 days, which may be increased to 3mg bid for another 5 days.
Participants will receive two doses of the GBS NN/NN2 vaccine on Days 1 and 29, respectively. On Day 57, they will receive a single dose of the Tdap vaccine administered in combination with a placebo, with both injections (Tdap and placebo) given in the same upper limb.
