The impact of market integration on arranged marriages in Matlab, Bangladesh. EVOLUTIONARY HUMAN SCIENCES 2022; 5:e5.

Abstract
Success in marriage markets has lasting impacts on women's wellbeing. By arranging marriages, parents exert financial and social powers to influence spouse characteristics and ensure optimal marriages. While arranging marriages is a major focus of parental investment, marriage decisions are also a source of conflict between parents and daughters in which parents often have more power. The process of market integration may alter parental investment strategies, however, increasing children's bargaining power and reducing parents' influence over children's marriage decisions. We use data from a market integrating region of Bangladesh to (a) describe temporal changes in marriage types, (b) identify which women enter arranged marriages and (c) determine how market integration affects patterns of arranged marriage. Most women's marriages were arranged, with love marriages more recent. We found few predictors of who entered arranged vs. love marriages, and family-level market integration did not predict marriage type at the individual level. However, based on descriptive findings, and findings relating women's and fathers' education to groom characteristics, we argue that at the society-level market integration has opened a novel path in which daughters use their own status, gained via parental investments, to facilitate good marriages under conditions of reduced parental assistance or control.

Social support, nutrition and health among women in rural Bangladesh: complex tradeoffs in allocare, kin proximity and support network size. Philos Trans R Soc Lond B Biol Sci 2021; 376:20200027.

Abstract
Malnutrition among women of reproductive age is a significant public health concern in low- and middle-income countries. Of particular concern are undernutrition from underweight and iron deficiency, along with overweight and obesity, all of which have negative health consequences for mothers and children. Accumulating evidence suggests that risk for poor nutritional outcomes may be mitigated by social support, yet how social support is measured varies tremendously and its effects likely vary by age, kinship and reproductive status. We examine the effects of different measures of social support on weight and iron nutrition among 677 randomly sampled women from rural Bangladesh. While we find that total support network size mitigates risk for underweight, other results point to a potential tradeoff in the effects of kin proximity, with nearby adult children associated with both lower risk for underweight and obesity and higher risk for iron deficiency and anaemia. Social support from kin may then enhance energy balance but not diet quality. Results also suggest that a woman's network of caregivers might reflect their greater need for help, as those who received more help with childcare and housework had worse iron nutrition. Overall, although some findings support the hypothesis that social support can be protective, others emphasize that social relationships often have neutral or negative effects, illustrating the kinds of tradeoffs expected from an evolutionary perspective. The complexities of these effects deserve attention in future work, particularly within public health, where what is defined as 'social support' is often assumed to be positive. This article is part of the theme issue 'Multidisciplinary perspectives on social support and maternal-child health'.

Abstract
PURPOSE Health disparities among LGBTQ people have been documented across various settings and recent research has indicated that many disparities are heightened in the context of rurality. Among these disparities is the decreased rate of primary care utilization by rural LGBTQ individuals. Understanding and addressing provider knowledge and attitudes related to LGBTQ health provides a relevant avenue for addressing underutilization. METHODS The study presented was a mail-out survey regarding rural primary care providers' knowledge and experiences regarding LGBTQ health. Publicly available records were compiled to recruit a total sample of 113 primary care providers, at a response rate of 19.8%. FINDINGS A majority of respondents reported experience providing care to LGBTQ patients, while only slightly over half had received LGBTQ health education. Data analyses revealed significant associations between reported experiences and patient characteristics including religion, religiousness, age, length of time practicing in current provider role, and gender identity. Provider knowledge of LGBTQ health varied greatly across the items assessed. Provider profession (physician, nurse practitioner, physician assistant) and length of current county residence were significantly predictive of LGBTQ knowledge scores. CONCLUSION Results provide insight into rural health care for LGBTQ people. Preeminent findings were: (1) an existing need for LGBTQ health education, (2) variation in knowledge across content areas, and (3) association between knowledge, profession, and length of current county residence. Promotion of rural LGBTQ health may benefit by addressing identified gaps in current care.

Abstract
Men who have sex with men (MSM) bear a disproportionate burden of HIV incidence in the United States. Previous study of sexual decision-making and HIV risk among MSM has not accounted for relationship dynamics. Further research must examine this connection between relationship dynamics and sexual decision-making, especially regarding condomless anal intercourse. This study analyzes data gathered from gay and bisexual men regarding their sexual partners and sexual decision-making over a 10-week period through personal relationship diaries (PRDs) and a follow-up in-depth interview (IDI). Through coding and extraction of relationship dynamics, key patterns of participants' sexual decision-making processes were examined based on relationship type, which was categorized by commitment, formality, and sexual agreement. Participants' sexual relationships can be divided into five categories: (a) Uncommitted, one time, (b) Uncommitted, ongoing, (c) Transitioning or unknown commitment, (d) Committed, nonmonogamous, and (e) Committed, monogamous. These five categories correspond to patterns in sexual decision making and consequent sexual risk-taking behaviors. Each of these influence HIV risk within male-male sexual encounters in a particular manner, and understanding these is important for appropriately tailored HIV prevention interventions for MSM. Recommendations are included for interventions seeking to address HIV risk across a wide variety of MSM sexual relationships.

Abstract
Combination prevention efforts are now recommended toward reducing HIV incidence among men who have sex with men (MSM). Understanding the perceptions of both MSM and service providers is critical to informing the development of prevention packages and ultimately improving intervention effectiveness. This study assessed the preferences of MSM and health service providers in the administration of HIV-prevention efforts. Qualitative data were gathered from a series of separate MSM and health care provider focus groups in 2 South African cities. Participants discussed HIV-prevention services and MSM client experiences within South Africa and identified the 3 most important clinic characteristics and 3 most important HIV-prevention services for MSM clients. Priorities indicated by both MSM and health care providers were confidentiality of visit, friendly staff, and condoms, while discrepancies existed between MSM and providers regarding provider consistency and the provision of pre-exposure prophylaxis/post-exposure prophylaxis (PrEP/PEP) and lubricant as prevention methods. Effective interventions must address these discrepancies through the design of intervention and provider training to optimally accommodate MSM.

Abstract
Background Prior studies have noted significant health disadvantages experienced by LGBT (lesbian, gay, bisexual, and transgender) populations in the US. While several studies have identified that fears or experiences of stigma and disclosure of sexual orientation and/or gender identity to health care providers are significant barriers to health care utilization for LGBT people, these studies have concentrated almost exclusively on urban samples. Little is known about the impact of stigma specifically for rural LGBT populations, who may have less access to quality, LGBT-sensitive care than LGBT people in urban centers. Methodology LBGT individuals residing in rural areas of the United States were recruited online to participate in a survey examining the relationship between stigma, disclosure and “outness,” and utilization of primary care services. Data were collected and analyzed regarding LGBT individuals’ demographics, health care access, health risk factors, health status, outness to social contacts and primary care provider, and anticipated, internalized, and enacted stigmas. Results Higher scores on stigma scales were associated with lower utilization of health services for the transgender & non-binary group, while higher levels of disclosure of sexual orientation were associated with greater utilization of health services for cisgender men. Conclusions The results demonstrate the role of stigma in shaping access to primary health care among rural LGBT people and point to the need for interventions focused towards decreasing stigma in health care settings or increasing patients’ disclosure of orientation or gender identity to providers. Such interventions have the potential to increase utilization of primary and preventive health care services by LGBT people in rural areas.

Abstract
Introduction The HIV/AIDS epidemic in America is rapidly progressing in certain subpopulations, including African-American and Hispanic communities. Churches may provide a means for reaching high-risk minority populations with effective HIV/AIDS prevention. We report on a series of focus group interviews conducted with Utah clergy who primarily serve African American and Hispanic congregations. Methods A total of three focus groups (two with Catholic clergy serving Hispanic congregations and one with protestant clergy serving African American congregations) were conducted with eleven participants, lasting approximately two hours each. Each focus group was audio-recorded and transcribed for analysis. Analysis of the data was conducted using a modified grounded theory approach. Results There were remarkable similarities in the attitudes and beliefs among all clergy participating in this study regarding HIV/AIDS and church-based prevention programs. All groups expressed concern about the diseases as a global epidemic and reported that the disease is highly preventable. Also, participants indicated a sense of responsibility to address the issues surrounding HIV/AIDS-related prevention, testing and care within their theological framework. Conclusion HIV/AIDS prevention and care for the infected are seen as falling within the scope of religious organizations. Openness to expanding efforts in this regard was shared by clergy participating in this study. Approaching religious leaders with tailored approaches that respect the values and practices of their particular religions will be more effective than attempting to impose approaches that do not achieve this standard.

Abstract
Near-infrared magneto-optical spectroscopy of single-walled carbon nanotubes reveals two absorption peaks with an equal strength at high magnetic fields (>55 T). We show that the peak separation is determined by the Aharonov-Bohm phase due to the tube-threading magnetic flux, which breaks the time-reversal symmetry and lifts the valley degeneracy. This field-induced symmetry breaking thus overcomes the Coulomb-induced intervalley mixing which is predicted to make the lowest exciton state optically inactive (or dark).

HYPOTHESIS Intraoperative ultrasonography is more sensitive than preoperative and other intraoperative techniques for localizing insulinoma. DESIGN Retrospective review. SETTING A tertiary referral center. PATIENTS All patients with a biochemical diagnosis of organic hyperinsulinism who were referred to University of California, San Francisco, from 1975 to 1998. METHODS Sensitivities of the localization techniques for insulinoma were evaluated. RESULTS The sensitivities of tumor localization with arteriography, computed tomography, preoperative ultrasonography, magnetic resonance imaging, magnetic resonance imaging with gadolinium, transhepatic venous sampling, palpation, and intraoperative ultrasonography were 47%, 24%, 50%, 30%, 40%, 55%, 76%, and 91%, respectively. Nine of the 11 nonpalpable and nonvisible tumors at operation were localized by intraoperative ultrasonography. CONCLUSION The currently available preoperative localization tests are not reliable enough to be recommended when intraoperative ultrasonography is available.

Abstract
The purpose of this study was to examine evidence for perceived stress, hypothalamic-pituitary-adrenal, and autonomic nervous system involvement in premenstrual symptoms. Women with a low severity (LS, n = 40), premenstrual syndrome (PMS, n = 22), and premenstrual magnification symptom patterns (PMM, n = 26) rated perceived stress, turmoil, and fluid retention symptoms for one entire cycle. Daily late afternoon urine samples were assayed for epinephrine, norepinephrine, and cortisol. Using multivariate analysis of variance analyses, we found significant group and cycle phase and group by phase interaction effects for perceived stress. There were no group or cycle phase differences in cortisol, epinephrine, and norepinephrine. Intraindividual analyses using cross-correlation techniques revealed a positive time lagged relationship between perceived stress and norepinephrine and cortisol levels across all groups. Only women with a PMS pattern demonstrated perceived stress leading epinephrine levels. Cortisol, epinephrine, and norepinephrine levels led symptoms for all groups with one exception: there was no cross-correlation between epinephrine and turmoil for the PMS group. Perceived stress led both types of symptoms, regardless of group, and symptoms also led stress. The results provide evidence for a unique relationship between epinephrine, perceived stress, and symptoms for women with PMS, and for a reciprocal relationship between stress and symptoms for each of the groups.

Abstract
BACKGROUND Women who report chronic gastrointestinal symptoms compatible with a diagnosis of irritable bowel syndrome (IBS) frequently report sleep disturbances. OBJECTIVES The purposes of this study were to (a) compare self-reported and polysomnographic indicators of sleep quality in women with IBS symptoms (IBS-SX, n= 16) and controls (n= 16); (b) examine the relationship between the indicators of sleep quality; and (c) determine the relationship between sleep indicators and psychological distress. METHOD The women slept in a laboratory for 2 consecutive nights. Polysomnographic measurements were recorded during sleep, and a sleep questionnaire was completed upon awakening each morning. Psychological distress was measured with the Symptom Checklist-90-R during the initial interview. RESULTS Women in the IBS-SX group reported significantly greater numbers of awakenings during sleep (p = .008) and had a longer latency to REM sleep (p = .04) than did the controls. Self-reported and polysomnographic indicators were more highly correlated in the control group than in the IBS-SX group. In the IBS-SX group, the greater the psychological distress, the less alert (rs = .419) and rested (rs = .564) the women felt in the morning and the more time the women spent in stages 3 and 4 sleep (rs = .479) and less in stage 2 (rs = -.447) and REM (rs = -.414) sleep. In the control group, psychological distress was not significantly associated with self-reported measures but was significantly associated with the number of awakenings (rs = .506) and time in stages 3 and 4 sleep (rs = -.677). CONCLUSIONS Although the women in the IBS-SX group reported significantly more awakenings, the weak relationship between self-reported and polysomnographic indicators suggests that clinicians must keep in mind that further assessments may be necessary.

Abstract
Insulinomas are rare tumors that originate from the islet cells of the pancreas. The purpose of this study was to analyze our experience in patients with insulinoma and present our approach to these patients. Medical records of 67 patients treated at the University of California, San Francisco (UCSF) Medical Center, 56 surgically and 11 medically, from 1954 to 1995 were retrospectively reviewed. Presenting symptoms, physical findings, laboratory data, pre and intraoperative localization studies, operative management, operative success, and post-operative complications were analyzed. Among the entire cohort, there were 11 patients with Multiple Endocrine Neoplasia type I (MEN 1) and 7 patients with multiple tumors. 46 out of 48 patients (96%) having first operations for benign tumors and 5 out of 8 patients (63%) having reoperations for benign tumors were successful, as were 6 out of 12 patients (50%) having operations for islet cell carcinoma. Overall, preoperative localization studies were positive in only 46% of patients and therefore failed to improve our surgical outcome. Careful palpation with intraoperative ultrasonography gave the best localization results. Enucleation of solitary tumors is curative in sporadic cases and gives the lowest complication rate. In patients with MEN 1, subtotal pancreatectomy with enucleation of tumours from the pancreatic head and uncinate process is recommended over simple enucleation because of frequent multiple tumors.

Abstract
The purpose of this study was to examine the relationships among perceived stress, ovarian steroids (estradiol and pregnanediol), stress arousal indicators (cortisol, catecholamines) and premenstrual symptoms (turmoil, fluid retention). Women (N = 74) with low symptom severity (LS), premenstrual syndrome (PMS), or premenstrual magnification (PMM) symptom patterns provided daily urine samples over one cycle and recorded their symptoms and perceived stress levels in a health diary. Multiple regression analysis was used to test models of premenstrual symptoms in separate analyses for women with the LS and PMS symptom patterns and the LS and PMM symptom patterns. Data from the LS and PMS groups revealed that greater stress ratings accounted for turmoil symptoms and higher luteal phase cortisol levels for fluid retention symptoms. For LS and PMM groups, lower luteal phase norepinephrine levels, higher global stress ratings, and a more gradual drop in estradiol premenses accounted for turmoil symptoms. Premenses norepinephrine and epinephrine levels and premenses stress ratings accounted for fluid retention. These findings support an important relationship among perceived stress, stress arousal indicators, and premenstrual symptoms that differs for women with a PMS and PMM symptom pattern.

Abstract
The purpose of this study was to compare women over 40 years of age with premenstrual syndrome (PMS) to women with a low-severity (LS) symptom pattern with respect to physiologic indicators of stress arousal and response, stress hormone arousal, stressful life circumstances, anger, self- and social control, and interpersonal sensitivity. Women with PMS experienced more negative life events, more difficulty with anger, and more concerns about self- and social control, than women with an LS pattern. These experiences were coupled with increased physiologic arousal and stress responses (skin conductance and muscle tension levels) and relatively higher norepinephrine levels than for women with an LS pattern, but with dampened cardiovascular responses to stressors. As they age, women with a PMS symptom pattern demonstrate persistent differences in stress arousal and response from women with an LS pattern.

Abstract
Hyperparathyroidism occurs sporadically, in association with multiple endocrine neoplasia (MEN) types I and II, or rarely as familial hyperparathyroidism (FHPT) without other manifestations. We analyzed our experience in 16 FHPT patients from 14 families treated between 1934 and 1991 and reviewed 51 other FHPT patients reported in the literature to determine the clinical course of these patients. Among our 16 patients, 7 (44%) had a serum calcium level >/= 3.75 mmol/L, 5 (31%) presented with hypercalcemic crisis, 3 (19%) had osteitis fibrosa cystica, 5 (31%) had nephrolithiasis, 1 had pancreatitis, 12 (75%) had multiple abnormal parathyroid glands, 3 (19%) had supernumerary glands, and 7 (44%) required reoperation for persistent (n = 4) or recurrent (n = 3) hyperparathyroidism. Three patients (19%) also had papillary thyroid cancer, and 7 (44%) had other coexistent thyroid disorders. Among 51 patients with FHPT reported in the literature, 23 (45%) had serum calcium >/= 3.75 mmol/L, and 23 (45%) had multiple abnormal parathyroid glands; 10 (20%) had recurrent hyperparathyroidism. FHPT without other endocrinopathies is a distinct entity. Patients with FHPT have multiple abnormal parathyroid glands and are prone to both recurrent and persistent hyperparathyroidism. They frequently present with profound hypercalcemia or hypercalcemic crisis, in contrast to patients with MEN-associated hyperparathyroidism or sporadic hyperparathyroidism.

Abstract
OBJECTIVES There are few data on the sympathetic nervous system and the hypothalamic-pituitary-adrenal axis in individuals with chronic GI symptoms. The current study was designed to describe and compare urine catecholamine (norepinephrine, epinephrine) and cortisol levels in women diagnosed with irritable bowel syndrome (IBS-patients), women who report similar symptom levels but had not sought health care services (IBS-nonpatients; IBS-NP), and asymptomatic (control) women. METHODS Seventy-three women (24 IBS; 24 IBS-NP; 25 controls) were interviewed for demographic, GI, gynecological, and psychological data and then followed for two menstrual cycles with a daily health diary. Urine samples were obtained in the evening and morning at specific phases across two menstrual cycles. RESULTS Women in the IBS group had significantly higher PM and AM urine norepinephrine levels. Urine epinephrine and cortisol levels were also generally higher in women with IBS. Differences in neuroendocrine indicators of arousal were not accounted for by differences in demographic variables, lifestyle characteristics, menstrual distress, or average daily measures of anxiety or depression. CONCLUSIONS Increases in indicators of sympathetic nervous system activation in women seeking health care for IBS may reflect greater symptom distress or may contribute to increased symptom distress.

Abstract
This study compared daily gastrointestinal symptoms and stool characteristics across two menstrual cycles, and recalled bowel symptoms and psychological distress in women with irritable bowel syndrome (IBS, N = 22), IBS nonpatients (IBS-NP, N = 22), and controls (N = 25). Daily reports of abdominal pain, bloating, intestinal gas, constipation, and diarrhea did not differ significantly between the IBS and IBS-NP groups but both groups reported significantly higher symptoms than the control group. Stool consistencies was significantly looser in the IBS group relative to the control group. Menstrual cycle effects on symptoms were noted in all the groups. There were no significant differences in psychological distress between women with IBS and IBS-NP, but both groups reported significantly higher global distress than the control group. The lack of difference between the IBS and IBS-NP groups in contrast to the results of others, can be understood in terms of differences in recruitment strategies.

Abstract
A carrot (Daucus carota, L.) genomic clone (DcPRP1) was isolated on the basis of its homology to previously described cDNAs encoding a wound-inducible, proline-rich cell wall protein. DNA sequence analysis showed that DcPRP1 contains a single open-reading frame encoding a 235-amino acid protein that is colinear with that predicted from the cDNA sequence with the exception of four amino acids at the N terminus and a 60-nucleotide insertion present within the genomic clone. Genomic Southern hybridization analysis showed that the cloned sequence hybridized with a single restriction enzyme fragment using several restriction enzymes. Primer extension and northern hybridization analysis indicated that the expression of DcPRP1 is developmentally regulated and linked to the formation of storage roots, where this gene is expressed at high levels after wounding. The level of DcPRP1 mRNA was greatest in tissue immediately adjacent to the wound site. Treatment of unwounded carrot storage roots with 10 microM 2,4-dichlorophenoxy-acetic acid, indoleacetic acid, or naphthalene-1-acetic acid also resulted in the accumulation of DcPRP1 transcripts to a level equal to that seen in wounded tissue.

Abstract
Dyspnea has been defined as the unpleasant sensation of difficult breathing and the reaction to that sensation. Dyspnea research, however, has largely used a unidimensional, sensory model of dyspnea devoid of the affective and motivational dimensions that uniquely characterize this sensation in clinical populations. Dyspnea might be more comprehensively viewed as a nociceptive phenomenon which, like pain, has affective dimensions expressed as distress in response to aversiveness. A multidimensional, ecologic model of the dyspnea experience is presented that incorporates nociceptive sensation properties and is suggestive of new directions for dyspnea research uniquely relevant to nursing science.

Variables for each of the four cardiovascular indicators (systolic blood pressure, diastolic blood pressure, heart rate, and premature ventricular contractions) included the value before, the highest value during, the lowest value during, and the value after each social interaction condition. The highest group means for systolic blood pressure and heart rate were significantly higher for patients with hypertension than for patients without hypertension under both the interview and visit conditions. Differences in cardiovascular responses were not significantly greater for family visits than for interviews for patients with hypertension compared with those without hypertension. Thus, although hypertensive patients had greater cardiovascular reactivity to both social interaction conditions than nonhypertensive patients in the coronary care unit, family visits were no more physiologically stressful than a comparative interaction condition.

Abstract
Integrated 12-hour growth hormone secretion studies, peak growth hormone response to clonidine provocation. Somatomedin-C levels, T-4 and TSH levels were studied in six growth-retarded children with the Prader-Willi syndrome, of whom five had a 15 q-karyotype. Only one of the subjects was obese. All showed abnormally low growth hormone secretion. None achieved a nocturnal peak above 10 micrograms/l, none had a mean nocturnal level over 1.8, and none showed a level above 8 micrograms/l after clonidine provocation. These findings contrasted with normal TSH in all and normal T-4 in five. These findings suggest that the poor linear growth in the Prader-Willi syndrome is caused by a true deficiency of growth hormone secretion, and that the low growth hormone levels observed in such cases are not an artifact of obesity.

Abstract
Changes in four cardiovascular indicators: systolic blood pressure, diastolic blood pressure, heart rate, and premature ventricular contractions, were studied as responses to family visits and a 10-minute interview with the investigator in 24 patients in a coronary care unit. By use of a repeated-measures design, data were compared by multivariate analysis of variance. No significant differences were found between the group mean systolic and diastolic blood pressure, heart rate, and rate of premature ventricular contractions during family visits and interviews. The lowest systolic and diastolic blood pressure values were significantly lower during the visit than during the interview, suggesting that the visit had a calming effect on patients. Although the highest heart rate was significantly higher during the visit than during the interview, the difference was clinically inconsequential. The wide variance in premature ventricular contraction values suggests individual variation in responses, but no significant differences were found between visits and interviews. Although family visits were no more physiologically stressful than a comparative social interaction, select subsamples of patients with cardiac disease should be studied for more specific reaction patterns.

Abstract
Women between the ages of 40 and 59 years were classified as pre-, peri-, and postmenopausal, with and without hot flash symptoms, for comparison of somnographic sleep variables. Few differences in sleep variables were noted between the groups. However, peri- and postmenopausal women experiencing hot flashes (symptomatic) tended to have lower sleep efficiencies than those not experiencing hot flashes. As well, rapid-eye-movement (REM) latency was longer (p less than 0.05) in the symptomatic women (means = 94.2 min) than in the nonsymptomatic women (means = 71.4 min). Although an age difference existed between the menopausal status groups, it was less than a decade and a main group effect for sleep efficiency and REM latency was seen while controlling for age and/or depression.

Abstract
The purpose of this study was to explore the effects of adaptive seating on oral-motor functioning as it relates to eating and drinking in 11 children with multiple handicaps between the ages of 1 and 4 years. An assessment instrument with a behavioral base was used for the seven direct observations of each child's motor behavior. During the first and last visit the parent or guardian filled out a pre- and post-equipment questionnaire. Evaluations were conducted every 6 weeks beginning 3 months before and ending 6 months after the receipt of the seating devices. An analysis of variance was used to analyze rating scale score data. A nonparametric sign test was used for the analysis of yes/no data. Other data were analyzed for frequencies and central tendencies. Sitting posture and head alignment during eating and drinking improved significantly. A significant increase in the frequency with which liquid and food was retained in the mouth was noted. A significant number of children progressed from bottle to cup drinking and from eating blended to chopped or cut-up food. The present research extends beyond case study and retrospective study reports to support the efficacy of the use of adaptive seating devices by children with multiple handicaps.

Abstract
Sequential measurement of QT interval during left ventricular angiography was made 30 seconds and one, three, five and ten minutes after injection of hypaque 76. The subjects were ten patients found to have normal left ventricles and coronary arteries. Significant QTC prolongation occurred in 30 seconds to one minute in association with marked hypotension and elevation of cardiac output.

Abstract
The hypothermic effect of resuscitation solution temperature on epicardial and core temperatures in 15 dogs during hemorrhagic shock was studied. Hemorrhagic shock was induced and dogs were then resuscitated with either body-temperature lactated Ringer's, room-temperature lactated Ringer's, 4 degrees C blood, warmed blood, or cold blood mixed with 50 degrees C lactated Ringer's. There was a significant decrease (p = 0.001) from baseline temperature recordings with the use of room-temperature lactated Ringer's, cold blood, and cold blood mixed with 50 degrees C lactated Ringer's. Baseline temperatures were not significantly changed with the use of warmed blood or body-temperature lactated Ringer's. The results of this study support the use of warmed blood or body-temperature lactated Ringer's during resuscitation from hemorrhagic shock.

Left atrial transport function. TRANSACTIONS OF THE AMERICAN CLINICAL AND CLIMATOLOGICAL ASSOCIATION 1981; 92:133-141.

Abstract
These studies show that the left atrial booster pump action serves as a supercharger which can increase left ventricular stroke volume in the range of 25 percent; and in patients with aortic stenosis, stroke work in the range of 50 percent (4). These changes can occur in the face of increased resistance to left ventricular filling in clinical conditions such as aortic stenosis where there is diminished left ventricular compliance and in mitral stenosis where there is stenotic resistance to left ventricular filling from the atrium. In spite of this fact, assessment of left atrial function by measurement of cardiac output changes occurring after return from atrial fibrillation to normal sinus rhythm yields erratic and confusing results. The reason for this is that atrial function, per se, is not a primary determinant of steady state cardiac output. Sequential A-V pacing may temporarily increase stroke volume in an acute setting like myocardial infarction. Nevertheless, one cannot infer from such observations that the use of permanent transvenous A-V sequential pacing will augment steady state cardiac output over a period of time. This is an important point to remember when considering the use of sequential A-V pacing, since it requires insertion of more complicated pacing and sensing wires as well as a more complex circuitry. All of these features lead to an increased risk of pacemaker malfunction. This increased risk of malfunction is not justified unless there is good evidence that atrial contribution is important in a given patient.
