Interaction Between Race and Gender on Implicit Racial Bias Against Blacks
Background and aims: Exposure and vulnerability to racial discrimination is not solely a function of
race but the intersection of race and gender, with Black men experiencing more discrimination than
Black women. This phenomenon is explained by the subordinate male target hypothesis, suggesting
that majority men specifically target men of color. If that is the case, implicit bias would be most
common among the majority men. The current cross-sectional study investigated race by gender
differences in implicit bias against Blacks.
Methods: Data came from Harvard University’s Project Implicit, an online survey, conducted during
2006-2016. Data included 444422 implicit association tests (IATs) which were taken by Blacks
(n=56384) and Whites (n=388038). Using IAT, the dependent variable was implicit bias against
Blacks. Independent variables were race, gender, and age. Using SPSS, linear regressions were utilized
to test the additive and multiplicative effects of race and gender on implicit bias against Blacks.
Results: Race (b = 0.39; 95% CI = 0.38-0.39) and gender (b = 0.05; 95% CI = 0.05-0.05) were
associated with IAT score suggesting higher implicit bias against Blacks among Whites and men. A
significant interaction was found between race and gender (b = 0.05; 95% CI = 0.04-0.07), suggesting
the highest level of implicit bias against Blacks among White men.
Conclusion: It is not solely race and gender but their intersection that shapes social distribution of
implicit bias against Blacks. This finding extends the previous literature showing that not solely race or
gender but their intersection influences exposure to discrimination.

Bidirectional associations between chronic medical conditions, disability, and depressive symptoms over 25 years: Black- White differences
Background and aims: Blacks have a higher rate of chronic medical conditions (CMC), disability, and depressive symptoms compared to Whites. The present study compared Blacks and Whites for bidirectional associations between CMC, disability, and depressive symptoms over a 25-year period. Methods: Data came from all five waves (1986, 1989, 1994, 2001, and 2011) of the Americans’ Changing Lives Study (ACL). This study followed 3,497 Whites and Blacks for up to 25 years. Number of CMC, disability, and depressive symptoms Center for Epidemiological Studies-Depression (CES-D) were measured at all waves. Multi-group crossed lag modeling was used to test four models, where race defined the groups. Results: Based on Models 1 and Model 2, cross-sectional associations between CMC and depressive symptoms at 1989, 2001, and 2011 were significant among Whites but not Blacks. Based on Model 3, lagged effect of CMC in 2001 on depressive symptoms in 2011 was only significant for Whites. Based on Model 4, cross-sectional associations between disability and depressive symptoms in 1989 were found among Whites but not Blacks. Conclusion: Compared to Whites, Blacks show fewer cross-sectional and longitudinal associations between CMC, disability, and depressive symptoms over time. These findings are robust, regardless of whether we conceptualize disability or depressive symptoms as the outcome
Intercourse Avoidance among Women with Coronary Artery Disease
Introduction Avoidance of sexual intercourse has not been frequently studied among patients with chronic medical conditions and patients with coronary artery disease ( CAD ) are not exception. Aim We aimed to (i) compare intercourse avoidance during the past 2 weeks among women with CAD and healthy controls; and (ii) to determine factors associated with intercourse avoidance during the past 2 weeks among women with CAD . Methods This study was conducted in an outpatient cardiology clinic in T ehran, I ran. The study included 152 married women with CAD and 50 controls. Socio‐demographic and clinical data including the severity of angina ( WHO R ose Q uestionnaire), risk factors (cigarette smoking, hyperlipidemia, diabetes, and obesity), fatigue, physical function (visual analogue scale [ VAS ]) and somatic comorbidities [ I fudu index], symptoms of anxiety and depression ( H ospital A nxiety and D epression S cale [ HADS ]), and dyadic adjustment ( R evised‐ D yadic A djustment S cale [ R ‐ DAS ]) were considered as independent variables. Logistic regression was used to determine predictors of sexual avoidance during the past 2 weeks. Main Outcome Measures The main outcome was intercourse avoidance over a 2‐week period, measured by the R elation and S exuality S cale ( RSS ). Result Avoidance of intercourse during the past 2 weeks was higher among women with CAD than controls (73.0% vs. 56%, P = 0.024). According to the logistic regression, intercourse avoidance was positively associated with age (Odds ratio [ OR ] = 1.127, 95% confidence interval [ CI ] = 1.073, 1.185), somatic comorbidities ( OR = 1.137, 95% CI = 1.061, 1.218) and depressive symptoms ( OR = 1.150, 95% CI = 1.022, 1.293). Conclusion Our study suggests that among women with CAD , age, depressive symptoms and somatic comorbidities are associated with avoidance of intercourse. As having intercourse is safe among patients with stable CAD , all health professionals should discuss sexual behaviors with their female CAD patients, especially those that are older, with higher depressive symptoms or multiple comorbidities so as to allay fears about sexual functioning.

Frequent mild head injury promotes trigeminal sensitivity concomitant with microglial proliferation, astrocytosis, and increased neuropeptide levels in the trigeminal pain system.
BACKGROUND: Frequent mild head injuries or concussion along with the presence of headache may contribute to the persistence of concussion symptoms.
METHODS: In this study, the acute effects of recovery between mild head injuries and the frequency of injuries on a headache behavior, trigeminal allodynia, was assessed using von Frey testing up to one week after injury, while histopathological changes in the trigeminal pain pathway were evaluated using western blot, ELISA and immunohistochemistry. RESULTS: A decreased recovery time combined with an increased mild closed head injury (CHI) frequency results in reduced trigeminal allodynia thresholds compared to controls. The repetitive CHI group with the highest injury frequency showed the greatest reduction in trigeminal thresholds along with greatest increased levels of calcitonin gene-related peptide (CGRP) in the trigeminal nucleus caudalis. Repetitive CHI resulted in astrogliosis in the central trigeminal system, increased GFAP protein levels in the sensory barrel cortex, and an increased number of microglia cells in the trigeminal nucleus caudalis.
CONCLUSIONS: Headache behavior in rats is dependent on the injury frequency and recovery interval between mild head injuries. A worsening of headache behavior after repetitive mild head injuries was concomitant with increases in CGRP levels, the presence of astrocytosis, and microglia proliferation in the central trigeminal pathway. Signaling between neurons and proliferating microglia in the trigeminal pain system may contribute to the initiation of acute headache after concussion or other traumatic brain injuries

Frequent use of stun gun may be associated with vibrationinduced Raynaud’s phenomenon: A case series
Introduction: Stun guns are energy-conducting weapons that are becoming more frequently
used by law enforcement officials to subdue combative individuals, or civilians for the case
of security. Although complications related to stun guns are well known for the victim, less is
known about stun guns complications among their users.
Case Series: In this case series, we reported vibration-induced Raynaud’s phenomenon
in four individuals who were recurrent users of stun guns. Two patients were male and two
were female. Symptoms varied from moderate to severe. Although both hands were involved,
symptoms were more severe in the right hand. Nifedipine was prescribed for all cases. Two
patients received Losartan, as well. All patients reported a decrease in their symptoms in
follow-up visits.
Conclusion: While further research is needed, clinicians should remain vigilant to stun gun
usage as a possible cause of Raynaud’s phenomenon
A prospective randomized clinical trial compared the effect of various types of local anesthetics cartridges on hypertensive patients during dental extraction
Objectives: To evaluate hemodynamic changes of blood pressure and heart rate on hypertensive patients under
-
going tooth extraction using various types of local anesthesia (LA).
Study Design: A prospective randomized clinical trial was conducted on 45 hypertensive patients who were divided
equally into 3 parallel groups according to LA received. Group 1: Lidociane 2% with epinephrine 1: 80,000. Group
2: Prilocaine 3% with Felypressin 0.03 IU/ml. Group 3: Mepivacaine 3% plain. Inclusion criteria: hypertensive
patients, under medical management with blood pressure = 159/99. Exclusion criteria: Blood pressure =160 /100
and patients receiving ß blockers. Negative aspiration was mandatory before the injection of 2 cartridges of LA.
Blood pressure and heart rate were evaluated by Electronic Sphygmomanometer and Pulse Oximeters in 3 different
time-points; 3 minutes before LA, three minutes after LA and three minutes after extraction.
Results: The mean of systolic blood pressure (SBP) had increased after LA injection, and then decreased after ex
-
traction in the 3 groups of patients. Increase of SBP after extraction with (Mepivacaine plain) was higher than (Li
-
dociane with Epinephrine) and the difference was statistically significant using ANOVA (
p
=0.037). The differences
in the mean heart rates and mean diastolic blood pressures in the 3 groups were not significant.
Conclusions: The increase of blood pressure with Epinephrine and Felypressin is negligible. Therefore, it is safe
to use 2 cartridges of Lidociane 2% with Epinephrine 1:80,000 or Prilocaine 3% with Felypressin 0.03 IU/ml for
hypertensive patients whose blood pressure = 159/99 provided negative aspiration is verified before injection
