Multiple Motor Learning Processes in Humans: Defining Their Neurophysiological Bases

Learning new motor behaviors or adjusting previously learned actions to account for dynamic changes in our environment requires the operation of multiple distinct motor learning processes, which rely on different neuronal substrates. For instance, humans are capable of acquiring new motor patterns via the formation of internal model representations of the movement dynamics and through positive reinforcement. In this review, we will discuss how changes in human physiological markers, assessed with noninvasive brain stimulation techniques from distinct brain regions, can be utilized to provide insights toward the distinct learning processes underlying motor learning. We will summarize the findings from several behavioral and neurophysiological studies that have made efforts to understand how distinct processes contribute to and interact when learning new motor behaviors. In particular, we will extensively review two types of behavioral processes described in human sensorimotor learning: (1) a recalibration process of a previously learned movement and (2) acquiring an entirely new motor control policy, such as learning to play an instrument. The selected studies will demonstrate in-detail how distinct physiological mechanisms contributions change depending on the time course of learning and the type of behaviors being learned.
Frecuencia relativa de Boophilus microplus (Acari: Ixodidae) en bovinos ( Bos taurus y B. indicus ) en ocho zonas ecológicas de Costa Rica

The research on the relative abundancy of Boophilus microplus took place in ten farms, distributed in eight ecological zones (EZ) and two rainfall systems of Costa Rica. Monthly visits were made to pick up ticks larger than 4mm from the right side of the animals. The total number of ticks was increased by two and divided between the total of sampled bovines per farm. Farm visits were adjusted to animals bath to allow the recovery of the tick population. B. microplus was detected in all sampled farms throughout the year. Media comparison statistic analyses were made and no differences were found among EZ, farms and seasons. On the contrary, there were important statistical differences between rainfall systems. The rainfall system 1, that included rain seasonality, showed larger tick infestations (p = 0.03). An isothermal and low variability regarding relative humidity situations were present in some of the areas included in this research. Bath intensity was lower to other past studies. Eventhough no differences were found between production systems, it is important to emphasize that bath intensity was higher in european cattle farms, in comparison to others of the same EZ, but of crossbred. A tick manual removable system was recommended in dual-purpose and specialized dairy farms with no more than 30-35 animals, as an alternative feasible system that significantly reduced acaricide use.
Understanding the Experience of Cancer Pain From the Perspective of Patients and Family Caregivers to Inform Design of an In-Home Smart Health System: Multimethod Approach

Background Inadequately managed pain is a serious problem for patients with cancer and those who care for them. Smart health systems can help with remote symptom monitoring and management, but they must be designed with meaningful end-user input. Objective This study aims to understand the experience of managing cancer pain at home from the perspective of both patients and family caregivers to inform design of the Behavioral and Environmental Sensing and Intervention for Cancer (BESI-C) smart health system. Methods This was a descriptive pilot study using a multimethod approach. Dyads of patients with cancer and difficult pain and their primary family caregivers were recruited from an outpatient oncology clinic. The participant interviews consisted of (1) open-ended questions to explore the overall experience of cancer pain at home, (2) ranking of variables on a Likert-type scale (0, no impact; 5, most impact) that may influence cancer pain at home, and (3) feedback regarding BESI-C system prototypes. Qualitative data were analyzed using a descriptive approach to identity patterns and key themes. Quantitative data were analyzed using SPSS; basic descriptive statistics and independent sample t tests were run. Results Our sample (n=22; 10 patient-caregiver dyads and 2 patients) uniformly described the experience of managing cancer pain at home as stressful and difficult. Key themes included (1) unpredictability of pain episodes; (2) impact of pain on daily life, especially the negative impact on sleep, activity, and social interactions; and (3) concerns regarding medications. Overall, taking pain medication was rated as the category with the highest impact on a patient’s pain (=4.79), followed by the categories of wellness (=3.60; sleep quality and quantity, physical activity, mood and oral intake) and interaction (=2.69; busyness of home, social or interpersonal interactions, physical closeness or proximity to others, and emotional closeness and connection to others). The category related to environmental factors (temperature, humidity, noise, and light) was rated with the lowest overall impact (=2.51). Patients and family caregivers expressed receptivity to the concept of BESI-C and reported a preference for using a wearable sensor (smart watch) to capture data related to the abrupt onset of difficult cancer pain. Conclusions Smart health systems to support cancer pain management should (1) account for the experience of both the patient and the caregiver, (2) prioritize passive monitoring of physiological and environmental variables to reduce burden, and (3) include functionality that can monitor and track medication intake and efficacy; wellness variables, such as sleep quality and quantity, physical activity, mood, and oral intake; and levels of social interaction and engagement. Systems must consider privacy and data sharing concerns and incorporate feasible strategies to capture and characterize rapid-onset symptoms.
NOTCH-1 Gene Mutations Influence Survival in Acute Myeloid Leukemia Patients

Background: Although NOTCH-1 gene mutations were reported to contributes to leukemogenesis in lymphocytic leukemias, its role in acute myeloid leukemia (AML) remains unclear. Therefor; this study was designed to determine the prevalence and clinical impact of NOTCH-1 mutations in AML patients. Materials and Methods: In the current study, NOTCH-1 gene mutations were identified in Bone Marrow samples obtained from fifty primary AML patients before start of therapy using Sanger sequencing. Results: NOTCH-1 gene mutations were detected in 6 out of 50 AML cases (12%). The three mutations were (two mutations C7318A in the Pest domain exon 34); (another 2 in the Pest domain Del 7,344, ins C7349, G7356A and the last ones in the HD-N exon-26 (Del A4609). The clinical findings in the mutant AML (mu AML) patients did not significantly different as compared to the un mutated (unmut) AML patients. There is significant association between CD7 aberrant expression and NOTCH-1 mutations. The complete remission was significantly higher in unmut AML cases as compared to mut AML ones (P=0.024). Multivariate (Age; Gender; Bone Marrow Blast cells; NOTCH-1 mutations) Cox regression analysis revealed that NOTCH-1 mutation is an independent risk factor for AML overall survival (P<0.001). The OS in unmut AML group (21.2 months) was significantly longer as compared to mut AML one (1.2 months) (P<0.001). Conclusion: Our data indicate that NOTCH-1 gene mutations were detected in 12% of AML patients. These mutations displayed bad clinical outcome on AML patients. Therapeutic targeting of NOTCH-1 could be a potentially effective approach to combat master oncogenic drivers in AML.
miR-140 and miR-196a as Potential Biomarkers in Breast Cancer Patients

Objective: MiR-140 and miR-196a were known to be correlated with cancer diagnosis and prognosis. The current study aimed at the analysis of miR-140 and miR-196a expression patterns and their clinical significance for breast cancer (BC) patients. Methods: Differentially expressed miR-140 and miR-196a were examined via quantitative PCR in 110 cases of BC and their adjacent non-tumor (ANT) tissues. Results: The results indicated that miR-140 and miR-196a, respectively, notably decreased and increased expression in BC samples in comparison with ANT (p<0.001). Reduced miR-140 expression was also related to Lymph node metastasis (LNM, P= 0.023) and stage (P = 0.009). Additionally, Receiver Operating Characteristics (ROC) analysis illustrated that miR-140 had a significant diagnostic accuracy for stage and LNM of BC patients. We also discovered a strong negative correlation between miR-196a expression with histological grade (P = 0.038), LNM (P = 0.012) and stage (P = 0.001). Conclusion: Overall, exploring the miR-140 and miR-196a profiles not only can statistically different among BC and ANT samples, but it is also expected to become potential BC biomarkers.
The Golden Compass Program: Overview of the Initial Implementation of a Comprehensive Program for Older Adults Living with HIV

The population with HIV is aging and has unique health needs. We present findings from an evaluation of the geriatric-HIV program, Golden Compass, at San Francisco General Hospital. We used the implementation science framework, RE-AIM (Reach, Effectiveness, Adoption, Implementation, Maintenance) to guide the evaluation and used quantitative and qualitative methods to assess RE-AIM dimensions. From January 2017 to June 2018, 198 adults age ≥50 years participated in the program, with an estimated reach of 17%. Providers and patients indicated high acceptability of the program and were satisfied with clinics and classes. Colocation of services, specific pharmacy and geriatric assessments, and social support from classes were valued (effectiveness). Provider adoption was high, and the program was implemented as originally designed. Areas for improvement included challenges of framing aging services to patients. Future efforts will focus on expanding the reach of the program and examining long-term outcomes.
ERCC1, XRCC1, and GSTP1 Polymorphisms and Treatment Outcomes of Advanced Epithelial Ovarian Cancer Patients Treated with Platinum-based Chemotherapy

Objective: The first line regimen for treating epithelial ovarian cancer (EOC) is platinum-based chemotherapy. Various factors impact its effectiveness including polymorphisms of enzymes in platinum-related metabolism processes. Methods: We conducted the study to investigate the association between polymorphisms of ERCC1, XRCC1 and GSTP1, which responsible for platinum’s metabolisms in Thai epithelial ovarian cancer patients. Results: Fifty-two patients with advanced epithelial ovarian cancer were enrolled into this study. Genotyping analysis of ERCC1 (C->A, rs3212986), XRCC1 (A->G, rs25487) and GSTP (A->G, rs1695) were performed which variant allele frequencies were found at 35.6%, 28.9% and 10.6%, respectively. Patients with homozygous variant type (A/A) of ERCC1 C8092A had higher rate of platinum-resistance (75% vs 16.7%, p =0.046). In addition, the significant association of GSTP1 polymorphism and grade 2 anemia was found. Patients with A/G genotype of GSTP1 had higher rate of grade 2 anemia (81.8% vs 46.3%, p =0.036). Conclusions: Genetic polymorphisms of ERCC1, and GSTP1 might be useful biomarkers for prediction of clinical benefit and toxicities of platinum-based chemotherapy in Thai epithelial ovarian cancer patients.
Growth and carbon partitioning in perennial ryegrass (Lolium perenne) cultivars selected for high water-soluble carbohydrate concentrations

Perennial ryegrass (Lolium perenne L.) cultivars with increased water-soluble carbohydrate (WSC) concentrations were evaluated under controlled environment conditions. The growth and carbon partitioning of these cultivars was compared with standard cultivars during vegetative growth. The high WSC cultivars had shoot growth rates that were not significantly different from the standard cultivars, confirming that the extra WSC in these cultivars was not made available through reductions in yield potential. The extra WSC stored in these cultivars coincided with lower concentrations of neutral detergent fibre in the dry matter. When the cultivars were grown in hydroponic solution the high WSC cultivars Aurora and Ba10727 were found to also have less root mass and a lower root[ratio ]shoot ratio than the standard cultivars. However, this trait was not consistent across all high WSC cultivars with Cariad having the same root[ratio ]shoot ratio as the standard cultivars at the end of the experiment. The reduction in the root mass of the cultivars Aurora and Ba10727 was far greater than necessary to provide the extra carbon stored as WSC in these cultivars. The implications of these results for the breeding of cultivars of perennial ryegrass with increased WSC concentrations are discussed.
DNA damage in mononuclear cells following maximal exercise in sedentary and physically active lean and obese men

We evaluated the impact of maximal exercise on oxidative stress and DNA damage in peripheral blood mononuclear cells (PBMC) from sedentary and exercised lean and obese men. PBMC were collected before, immediately and 1-h after exercise and exposed to hydrogen peroxide (H2O2; 25 and 50 µM, 4 h). A leukocytosis was induced by maximal exercise immediately and 1-h after exercise in all groups. However, a lymphopenia was observed 1-h after exercise in the Sedentary obese group. In the control condition, low DNA damage index concomitant to increases in intracellular glutathione content (GSH) was identified immediately after exercise in all groups. However, higher DNA damage index and lipid peroxidation occurred 1-h after the bout in Sedentary and Exercised Obese groups. PBMC exposed to both H2O2 25 and 50 µM experienced higher DNA damage and lipid peroxidation index immediately after exercise in all groups. Both lipid peroxidation and DNA damage index remained higher in PBMC of Sedentary Lean, Sedentary Obese, and Exercised obese groups obtained 1-h after exercise in both H2O2 25 and 50 µM, with the highest values identified in PBMC from Sedentary Obese group. However, increases in GSH content were identified in treated PBMC from sedentary and exercised lean groups as well as exercised obese group 1-h after exercise. Habitual exercise confers increased resistance of PBMC to DNA damage induced by oxidative stress, reducing the detrimental effects of obesity.

Anticipated emotional and behavioral responses to ambiguous rejection by a significant other, friend, or acquaintance

Abstract Although there is an extensive literature on interpersonal rejection, individual studies that have examined adults’ emotional and behavioral responses to rejection have tended to limit their scope to a specific category of rejector (e.g., acquaintances). As a result, prior research has failed to systematically investigate whether individuals’ emotional and behavioral responses to perceived rejection differ as a function of the role of the potential rejector. In the present study, a total of 481 participants read two scenarios describing hypothetical situations in which rejection by a specific individual (i.e., significant other, friend, or acquaintance) was ambiguous. After each scenario, participants rated the extent to which they would be likely to anticipate (a) experiencing various negative emotions (e.g., upset) and (b) engaging in various behavioral responses (i.e., act friendly, retaliate, complain, avoid) to the potential rejector. Overall, the potential of being rejected by another person with whom one has a close and valued relationship (i.e., a significant other and, to a lesser degree, a friend) was associated with heightened negative emotion and a heightened likelihood of engaging in an active response, either prosocial (i.e., act friendly) or antisocial (i.e., retaliate or complain). In contrast, potential rejection by an acquaintance was associated with relatively little negative emotion and relatively little desire to engage the other (i.e., avoid). In sum, the participants’ relationship with specific individuals was found to influence both the intensity of their anticipated negative emotional response to ambiguous rejection and the pattern of their anticipated behavioral response to the potential rejectors.
An update on the clinical pharmacology of methylphenidate: therapeutic efficacy, abuse potential and future considerations

ABSTRACT Introduction Methylphenidate remains a first-line medication for treating ADHD in children and adults. However, its behavioral pharmacological similarities to methamphetamine and cocaine have historically created concern for its potential as a drug of abuse. In September 2019, the FDA published a docket requesting comments for the development of abuse deterrent formulations for CNS stimulants, emphasizing the abuse of methylphenidate as a public health concern. Areas covered We conducted a narrative review of research on the clinical pharmacology, therapeutic efficacy, and abuse potential of methylphenidate. Expert opinion Several studies indicate that methylphenidate has at least some abuse potential. Methylphenidate, amphetamine, methamphetamine, and cocaine overlap in their subjective, reinforcing, and discriminative stimulus effects. Regardless, methylphenidate remains an efficacious treatment for ADHD in children and adults when properly adhered to, especially when paired with non-pharmacological treatments. The development of abuse deterrent formulations of methylphenidate is warranted.
Cerebral Small‐Vessel Disease and Risk of Incidence of Depression: A Meta‐Analysis of Longitudinal Cohort Studies

Background Results of several longitudinal cohort studies suggested an association between cerebral small‐vessel disease and depression. Therefore, we performed a meta‐analysis to explore whether cerebral small‐vessel disease imparts increased risk for incident depression. Methods and Results We searched prospective cohort studies relevant to the relationship between cerebral small‐vessel disease and incident depression published through September 6, 2019, which yielded 16 cohort studies for meta‐analysis based on the relative odds ratio (OR) calculated with fixed‐ and random‐effect models. Baseline white matter hyperintensities (WMHs) (pooled OR, 1.37; 95% CI, 1.14–1.65), enlarged perivascular spaces (pooled OR, 1.33; 95% CI, 1.03–1.71), and cerebral atrophy (pooled OR, 2.83; 95% CI, 1.54–5.23) were significant risk factors for incident depression. Presence of deep WMHs (pooled OR, 1.47; 95% CI, 1.05–2.06) was a stronger predictor of depression than were periventricular WMHs (pooled OR, 1.31; 95% CI, 0.93–1.86). What's more, the pooled OR increased from 1.20 for the second quartile to 1.96 for the fourth quartile, indicating that higher the WMH severity brings greater risk of incident depression (25th–50th: pooled OR, 1.20; 95% CI, 0.68–2.12; 50th–75th; pooled OR, 1.42; 95% CI, 0.81–2.46; 75th–100th: OR, 1.96; 95% CI, 1.06–3.64). These results were stable to subgroup analysis for age, source of participants, follow‐up time, and methods for assessing WMHs and depression. Conclusions Cerebral small‐vessel disease features such as WMHs, enlarged perivascular spaces, and cerebral atrophy, especially the severity of WMHs and deep WMHs, are risk factors for incident depression.
Intimate Partner Violence Victimization and Depressive Symptoms in Sichuan, China: Are There Gender Variations?

An emerging body of research has linked intimate partner violence (IPV) victimization with negative mental health outcomes among women in postreform China. However, limited scholarly attention has been given to the independent effects of multiple types of IPV victimization on depressive symptoms among men and women. Little is known if these independent effects will vary by gender in China where research on the association between IPV victimization and mental health did not emerge until fairly recently. Given this research paucity, this study aims to (a) examine the independent effects of different types of lifetime IPV victimization among married men and women in Sichuan province on their self-reported past 30-day depressive symptoms and (b) explore possible gender variations in these effects. The data utilized in this study came from a subsample of married men (N = 1,083) and women (N = 1,185) from the Third Survey of Chinese Women’s Social Status 2010, a representative sample of adults aged 18 to 64 in Sichuan province. Statistical analyses indicate that all types of lifetime IPV victimization are significantly and positively associated with past 30-day depressive symptoms for women, whereas for men lifetime experiences of general controlling behavior and sexual IPV were not statistically associated with depressive symptoms. Moreover, the effects of multiple types of IPV victimization on depressive symptoms do not significantly vary by gender. Bearing this gender-neutral pattern in mind, health professionals, governmental officials, and researchers are strongly encouraged to focus on both married men and women in their IPV and mental health intervention, prevention, and treatment endeavors in postreform China.

A b s t r a c t. High rate of degradation of the swamp-minnow Eupallasella perenurus habitats in the Polesie Lubelskie, Poland, as well as disappearance of some of the only few populations of this species known to exist there have been observed over recent decades. This fact was the basic premise justifying the beginning of studies on the actual state of the swamp-minnow populations in this area. In the present paper, preliminary results of these studies are presented. K e y w o r d s: swamp-minnow, occurrence, Polesie Lubelskie
Chronic Pain Personification Following Child Abuse: The Imprinted Experience of Child Abuse in Later Chronic Pain

Child abuse has been shown to increase the risk for chronic pain. The illness personification theory implies that individuals tend to ascribe humanlike characteristics to chronic pain, and that this personification is embedded in the way they cope with their chronic condition. Recent findings demonstrate that individuals who experienced interpersonal violence tend to personify chronic pain in a way that resonates with past abusive experience. Although findings prevail to the link between trauma and the experience of the body, the personification of chronic pain among individuals who experienced child abuse has not been examined before. This article includes two studies that tested whether child abuse is implicated in abusive chronic pain personification in a young adult female sample (Study 1) and among females who experienced child abuse (Study 2). In both studies, self-report measures of child abuse, posttraumatic stress (PTS) symptoms, complex posttraumatic symptoms (disturbances of self-organization [DSO]), and abusive chronic pain personification were administered. Structural equation modeling was utilized to assess the hypotheses. The findings of the two studies showed a significant association between child abuse and pain personification. Whereas PTS symptoms did not mediate this link (Study 1), DSO symptoms mediated this association (Study 2). The findings of these studies support the understanding that the experience of interpersonal violence is engraved in the experience of the body, as reflected in abusive chronic pain personification. Disturbances in self-organization seem to underlie this process, thus pertaining to the link between the experience of the body, self, and interpersonal trauma.
