The study draws on oral histories of women participants in this project as a way to contribute these omitted "voices" to the canon of journalism, civil rights, and women's history. In analyzing these stories, this study discovered generational differences among the women in terms of Freedom Summer's influence on their worldviews and subsequent vocations. Although all of the study's participants performed journalistic tasks, the older women of this group continued their lives as social activists and the younger women became professional communicators. The rationale for this phenomena helps explain, in part, the omission of women from the historical "image" of African American civil rights leaders.Includes bibliographical reference

Weekend effect: analysing temporal trends in solid organ donation

Background: Research suggests patients treated over weekends experience poorer outcomes. Only one US-based study explored this weekend effect in organ donation, specifically the kidney discard rate. In Australia potential donors are referred to a donation service, and donation proceeds if family consent is granted and the donor is deemed medically suitable to donate. Organ procurement occurs when utilization is almost certain hence discard rates are much lower than in the USA. We aimed to characterize the effect of weekend referral on organ donation in Australia. Methods: We retrospectively reviewed all New South Wales Organ and Tissue Donation Service logs from 2010 to 2016. Our primary outcome was progression to organ procurement, and secondary outcomes were family consent and meeting medical suitability thresholds. We used logistic regression with random effects adjusting for clustering of referral hospitals. Results: Of 3496 potential donors referred for consideration, 694 (20%) progressed to organ procurement. There were fewer referrals on weekends (average 415 versus 588 for weekdays). However, donation rates were no lower for weekend compared to weekday referrals (adjusted OR 1.17; 95% CI 0.95, 1.44). Family consent (adjusted OR 1.20; 95% CI 1.00, 1.44) and medical suitability (adjusted OR 1.15; 95% CI 0.96, 1.38) were not lower for weekend compared to weekday referrals. Similar results were found for all sensitivity analyses conducted. Conclusions: In Australia, the donation pathway operates consistently throughout the week, with donation no less likely to proceed on weekends and holidays. This finding contrasts with findings in the USA

Acceptability of Early Infant Male Circumcision as an HIV Prevention Intervention in Zimbabwe: A Qualitative Perspective

Background Early infant male circumcision (EIMC) is simpler, safer and more cost-effective than adult circumcision. In sub-Saharan Africa, there are concerns about acceptability of EIMC which could affect uptake. In 2009 a quantitative survey of 2,746 rural Zimbabweans (aged 18–44) indicated that 60% of women and 58% of men would be willing to have their newborn son circumcised. Willingness was associated with knowledge of HIV and male circumcision. This qualitative study was conducted to better understand this issue. Methods In 2010, 24 group discussions were held across Zimbabwe with participants from seven ethnic groups. Additionally, key informant interviews were held with private paediatricians who offer EIMC (n = 2) plus one traditional leader. Discussions were audio-recorded, transcribed, translated into English (where necessary), coded using NVivo 8 and analysed using grounded theory principles. Results Knowledge of the procedure was poor. Despite this, acceptability of EIMC was high among parents from most ethnic groups. Discussions suggested that fathers would make the ultimate decision regarding EIMC although mothers and extended family can have (often covert) influence. Participants' concerns centred on: safety, motive behind free service provision plus handling and disposal of the discarded foreskin. Older men from the dominant traditionally circumcising population strongly opposed EIMC, arguing that it separates circumcision from adolescent initiation, as well as allowing women (mothers) to nurse the wound, considered taboo. Conclusions EIMC is likely to be an acceptable HIV prevention intervention for most populations in Zimbabwe, if barriers to uptake are appropriately addressed and fathers are specifically targeted by the programme

Sex differences in mortality among binational cohort of people with chronic kidney disease: population based data linkage study

Objective To evaluate sex differences in mortality among people with kidney failure compared with the general population. Design Population based cohort study using data linkage. Setting The Australian and New Zealand Dialysis and Transplant Registry (ANZDATA), which includes all patients receiving kidney replacement therapy in Australia (1980-2019) and New Zealand (1988-2019). Data were linked to national death registers to determine deaths and their causes, with additional details obtained from ANZDATA. Participants Of 82 844 people with kidney failure, 33 329 were female (40%) and 49 555 were male (60%); 49 376 deaths (20 099 in female patients; 29 277 in male patients) were recorded over a total of 536 602 person years of follow-up. Main outcome measures Relative measures of survival, including standardised mortality ratios, relative survival, and years of life lost, using general population data to account for background mortality (adjusting for country, age, sex, and year). Estimates were stratified by dialysis modality (haemodialysis or peritoneal dialysis) and for the subpopulation of kidney transplant recipients. Results Few differences in outcomes were found between male and female patients with kidney failure. However, compared with the general population, female patients with kidney failure had greater excess all cause deaths than male patients (female patients: standardised mortality ratio 11.3, 95% confidence interval 11.2 to 11.5, expected deaths 1781, observed deaths 20 099; male patients: 6.9, 6.8 to 6.9, expected deaths 4272, observed deaths 29 277). The greatest difference was observed among younger patients and those who died from cardiovascular disease. Relative survival was also consistently lower in female patients, with adjusted excess mortality 11% higher (95% confidence interval 8% to 13%). Average years of life lost was 3.6 years (95% confidence interval 3.6 to 3.7) greater in female patients with kidney failure compared with male patients across all ages. No major differences were found in mortality by sex for haemodialysis or peritoneal dialysis. Kidney transplantation reduced but did not entirely remove the sex difference in excess mortality, with similar relative survival (P=0.83) and years of life lost difference reduced to 2.3 years (95% confidence interval 2.2 to 2.3) between female and male patients. Conclusions Compared with the general population, female patients had greater excess deaths, worse relative survival, and more years of life lost than male patients, however kidney transplantation reduced these differences. Future research should investigate whether systematic differences exist in access to care and possible strategies to mitigate excess mortality among female patients

Serum Persistent Organic Pollutants and Duration of Lactation among Mexican-American Women

Background. Research suggests that estrogenic endocrine-disrupting chemicals interfere with lactation. Objectives. (1) to determine if estrogenic persistent organic pollutants (POPs) are associated with shortened lactation duration; (2) to determine whether previous breastfeeding history biases associations. Methods and Results. We measured selected organochlorines and polychlorinated biphenyls (p, p′-DDE, p, p′-DDT, o, p′-DDT, β-hexachlorocyclohexane, hexachlorobenzene, and PCBs 44, 49, 52, 118, 138, 153, and 180) in serum from 366 low-income, Mexican-American pregnant women living in an agricultural region of California and assessed breastfeeding duration by questionnaires. We found no association between DDE, DDT, or estrogenic POPs with shortened lactation duration, but rather associations for two potentially estrogenic POPs with lengthened lactation duration arose (HR [95% CI]: 0.6 [0.4, 0.8] for p, p′-DDE & 0.8 [0.6, 1.0] for PCB 52). Associations between antiestrogenic POPs (PCBs 138 and 180) and shortened lactation duration were attributed to a lactation history bias. Conclusion. Estrogenic POPs were not associated with shortened lactation duration, but may be associated with longer lactation duration

Cognitive and language performance predicts effects of spelling intervention and tDCS in Primary Progressive Aphasia

Predictors of treatment effects allow individual tailoring of treatment characteristics, thereby saving resources and optimizing outcomes. Electrical stimulation coupled with language intervention has shown promising results in improving language performance in individuals with Primary Progressive Aphasia (PPA). The current study aimed to identify language and cognitive variables associated with response to therapy consisting of language intervention combined with transcranial direct current stimulation (tDCS). Forty individuals with PPA received written naming/spelling intervention combined with anodal tDCS or Sham, using a between-subjects, randomized design, with intervention delivered over a period of 3 weeks. Participants were assessed using a battery of neuropsychological tests before and after each phase. We measured letter accuracy during spelling of trained and untrained words, before, immediately after, 2 weeks, and 2 months after therapy. We used step-wise regression methods to identify variables amongst the neuropsychological measures and experimental factors that were significantly associated with therapy outcomes at each time-point. For trained words, improvement was related to pre-therapy scores, in RAVLT (5 trials sum), pseudoword spelling, object naming, digit span backward, spatial span backward and years post symptom onset. Regarding generalization to untrained words, improvement in spelling was associated with pseudoword spelling, RAVLT proactive interference, RAVLT immediate recall. Generalization effects were larger under tDCS compared to Sham at the 2-month post training measurement. We conclude that, for trained words, patients who improve the most are those who retain for longer language skills such as sublexical spelling processes (phoneme-to-grapheme correspondences) and word retrieval, and other cognitive functions such as executive functions and working memory, and those who have a better learning capacity. Generalization to untrained words occurs through improvement in knowledge of phoneme-to-grapheme correspondences. Furthermore, tDCS enhances the generalizability and duration of therapy effects

Transplant Recipients and Anal Neoplasia Study: Design, Methods, and Participant Characteristics of a Prevalence Study

Kidney recipients have anal cancer rates 3 times higher than the general population in Australia and New Zealand. High-risk human papillomavirus (HPV) genotypes are implicated in the majority of anal cancers. Establishing the epidemiology of anal HPV infection and precursors of anal cancer in transplant recipient populations is 1 consideration in any potential screening program. The Transplant and Anal Neoplasia Study is a cross-sectional study of the prevalence of anal cytological abnormalities and HPV deoxyribonucleic acid in kidney transplant recipients, as well as evaluating the acceptability of an anal cancer screening intervention. The study aims to recruit 100 kidney transplant recipients, older than 18 years, in Australia. Transplant recipients at- tending for a protocol biopsy at 3 and 12 months and annually posttransplant are approached to participate. Participants undergo an anal swab, which is then analyzed using liquid-based cytological examination and tested for the detection of 37 anogenital HPV deoxyribonucleic acid genotypes. Participants also complete a demographic and behavioral questionnaire that covers sexual be- havior, history of anal symptoms, and possible anal cancer risk factors. Associations will be tested using multiple regression anal- ysis. Recruitment for the study began in 2015 and is ongoing. To date, 96 (77%) of 125 kidney transplant recipients approached have consented to the study. The mean age is 48 (median, 47 y; range, 20–76 y), 59% are male, and Northwest European (58%) represented the largest ethnic group. No participants self-identified as Aboriginal or Torres Strait Islander. High consent rates and positive qualitative results suggest that a larger screening program may be well received by kidney transplant recipients, with in- creased resources and some modification to the timing of approach. Further results of the study will inform the possible implemen- tation of a larger screening trial for prevention of anal cancers in kidney and other solid organ transplant recipients

In Vitro and In Vivo Characterization of the Alkaloid Nuciferine

RationaleThe sacred lotus (Nelumbo nucifera) contains many phytochemicals and has a history of human use. To determine which compounds may be responsible for reported psychotropic effects, we used in silico predictions of the identified phytochemicals. Nuciferine, an alkaloid component of Nelumbo nucifera and Nymphaea caerulea, had a predicted molecular profile similar to antipsychotic compounds. Our study characterizes nuciferine using in vitro and in vivo pharmacological assays.MethodsNuciferine was first characterized in silico using the similarity ensemble approach, and was followed by further characterization and validation using the Psychoactive Drug Screening Program of the National Institute of Mental Health. Nuciferine was then tested in vivo in the head-twitch response, pre-pulse inhibition, hyperlocomotor activity, and drug discrimination paradigms.ResultsNuciferine shares a receptor profile similar to aripiprazole-like antipsychotic drugs. Nuciferine was an antagonist at 5-HT2A, 5-HT2C, and 5-HT2B, an inverse agonist at 5-HT7, a partial agonist at D2, D5 and 5-HT6, an agonist at 5-HT1A and D4 receptors, and inhibited the dopamine transporter. In rodent models relevant to antipsychotic drug action, nuciferine blocked head-twitch responses and discriminative stimulus effects of a 5-HT2A agonist, substituted for clozapine discriminative stimulus, enhanced amphetamine induced locomotor activity, inhibited phencyclidine (PCP)-induced locomotor activity, and rescued PCP-induced disruption of prepulse inhibition without induction of catalepsy.ConclusionsThe molecular profile of nuciferine was similar but not identical to that shared with several approved antipsychotic drugs suggesting that nuciferine has atypical antipsychotic-like actions
