'Beer used to belong to older men': drink and authority among the Nyakyusa of Tanzania

In her last major work on social change among the Nyakyusa of southwestern Tanzania, Monica Wilson returned to an argument about the changing role of beer drinking which had featured in her earlier writings (1963: 176, 1977: 92-3, 131). She suggested that the selling of locally made grain beer for cash, and its consumption in commercial clubs, had played a major role in altering relationships between young and old, and men and women. Generational separation had broken down: young men had lost respect for elder men and women had acquired a new economic autonomy founded on the cash income they earned from selling beer. Beer thus lay at the heart of a pattern of social change (1977: 186). This article examines changes in authority and the drinking of beer in Nyakyusa society from the 1890s-when written records become available-to the end of the twentieth century. It argues that patterns of deference and authority have suffered less dislocation than Wilson suggested and that-while locally made grain beer has been physically transformed, has disappeared from certain public rituals of well-being and has come increasingly into the cash market-its commoditisation has not necessarily empowered women, nor has it eliminated the role of beer in patterns of behaviour and discourse which sustain elder men's claims to authority

Distribution of cytochrome P450 2C, 2E1, 3A4, and 3A5 in human colon mucosa

BACKGROUND: Despite the fact that the alimentary tract is part of the body's first line of defense against orally ingested xenobiotica, little is known about the distribution and expression of cytochrome P450 (CYP) enzymes in human colon. Therefore, expression and protein levels of four representative CYPs (CYP2C(8), CYP2E1, CYP3A4, and CYP3A5) were determined in human colon mucosa biopsies obtained from ascending, descending and sigmoid colon. METHODS: Expression of CYP2C, CYP2E1, CYP3A4, and CYP3A5 mRNA in colon mucosa was determined by RT-PCR. Protein concentration of CYPs was determined using Western blot methods. RESULTS: Extensive interindividual variability was found for the expression of most of the genes. However, expression of CYP2C mRNA levels were significantly higher in the ascending colon than in the sigmoid colon. In contrast, mRNA levels of CYP2E1 and CYP3A5 were significantly lower in the ascending colon in comparison to the descending and sigmoid colon. In sigmoid colon protein levels of CYP2C8 were significantly higher by ~73% than in the descending colon. In contrast, protein concentration of CYP2E1 was significantly lower by ~81% in the sigmoid colon in comparison to the descending colon. CONCLUSION: The current data suggest that the expression of CYP2C, CYP2E1, and CYP3A5 varies in different parts of the colon

Prevalence and impact of alcohol and other drug use disorders on sedation and mechanical ventilation: a retrospective study

BACKGROUND: Experience suggests that patients with alcohol and other drug use disorders (AOD) are commonly cared for in our intensive care units (ICU's) and require more sedation. We sought to determine the impact of AOD on sedation requirement and mechanical ventilation (MV) duration. METHODS: Retrospective review of randomly selected records of adult patients undergoing MV in the medical ICU. Diagnoses of AOD were identified using strict criteria in Diagnostic and Statistical Manual of Mental Disorders, and through review of medical records and toxicology results. RESULTS: Of the 70 MV patients reviewed, 27 had AOD (39%). Implicated substances were alcohol in 22 patients, cocaine in 5, heroin in 2, opioids in 2, marijuana in 2. There was no difference between AOD and non-AOD patients in age, race, or reason for MV, but patients with AOD were more likely to be male (21 versus 15, p < 0.0001) and had a lower mean Acute Physiology and Chronic Health Evaluation II (22 versus 26, p = 0.048). While AOD patients received more lorazepam equivalents (0.5 versus 0.2 mg/kg.day, p = 0.004), morphine equivalents (0.5 versus 0.1 mg/kg.day, p = 0.03) and longer duration of infusions (16 versus 10 hours/day. medication, p = 0.002), they had similar sedation levels (Richmond Agitation-Sedation Scale (RASS) -2 versus -2, p = 0.83), incidence of agitation (RASS ≥ 3: 3.0% versus 2.4% of observations, p = 0.33), and duration of MV (3.6 versus 3.9 days, p = 0.89) as those without AOD. CONCLUSION: The prevalence of AOD among medical ICU patients undergoing MV is high. Patients with AOD receive higher doses of sedation than their non-AOD counterparts to achieve similar RASS scores but do not undergo longer duration of MV

Acetate Causes Alcohol Hangover Headache in Rats

Background: The mechanism of veisalgia cephalgia or hangover headache is unknown. Despite a lack of mechanistic studies, there are a number of theories positing congeners, dehydration, or the ethanol metabolite acetaldehyde as causes of hangover headache. Methods: We used a chronic headache model to examine how pure ethanol produces increased sensitivity for nociceptive behaviors in normally hydrated rats. Results: Ethanol initially decreased sensitivity to mechanical stimuli on the face (analgesia), followed 4 to 6 hours later by inflammatory pain. Inhibiting alcohol dehydrogenase extended the analgesia whereas inhibiting aldehyde dehydrogenase decreased analgesia. Neither treatment had nociceptive effects. Direct administration of acetate increased nociceptive behaviors suggesting that acetate, not acetaldehyde, accumulation results in hangover-like hypersensitivity in our model. Since adenosine accumulation is a result of acetate formation, we administered an adenosine antagonist that blocked hypersensitivity. Discussion: Our study shows that acetate contributes to hangover headache. These findings provide insight into the mechanism of hangover headache and the mechanism of headache induction

Liposomal bupivacaine infiltration into the transversus abdominis plane for postsurgical analgesia in open abdominal umbilical hernia repair: results from a cohort of 13 patients

Dennis E Feierman, Mark Kronenfeld, Piyush M Gupta, Natalie Younger, Eduard Logvinskiy Department of Anesthesiology, Maimonides Medical Center, Brooklyn, NY, USA Background: Achieving adequate control of postsurgical pain remains a challenge in patients undergoing abdominal surgery. Transversus abdominis plane (TAP) infiltration has been shown to provide postsurgical analgesia following lower abdominal surgery. We assessed the safety and efficacy of a prolonged-release liposomal formulation of the local anesthetic bupivacaine administered via infiltration into the TAP in a cohort of patients undergoing open abdominal umbilical hernia repair. Methods: Patients included in the study were 18&ndash;75 years of age, had American Society of Anesthesiologists physical classification status 1&ndash;3, and underwent open abdominal umbilical hernia repair with ultrasound-guided TAP infiltration immediately after surgery using an equal-volume bilateral infusion of liposomal bupivacaine 266 mg (diluted to 30 mL in normal saline). Outcome measures included patient-reported pain intensity (11-point numeric rating scale), satisfaction with postsurgical analgesia (5-point Likert scale), incidence of opioid-related adverse events, and time to first use of supplemental rescue analgesia. Results: Thirteen patients underwent surgery and received bilateral TAP infiltration with liposomal bupivacaine; TAP infiltration failed in the first patient. Mean numeric rating scale pain scores were 0.6 immediately before TAP infiltration and remained 2.3 through 120 hours after infiltration; mean scores at 120 hours and 10 days were 0.9 and 0.4, respectively. Ten patients (77%) required supplemental analgesia; median time to first use was 11 hours. At discharge and day 10, 54% and 62% of patients, respectively, were &ldquo;extremely satisfied&rdquo; with postsurgical analgesia (Likert score 5). There were no opioid-related or other adverse events. Conclusion: Although the current study was limited by both its lack of a control group and its small size, to our knowledge, it is the first published report on use of liposomal bupivacaine for TAP infiltration. In this cohort, liposomal bupivacaine was observed to be well tolerated with encouraging analgesic efficacy.
