Unreliability of radiodilution assays as screening tests for cobalamin (vitamin B12) deficiency
Authors: K. L. Cohen
Journal: JAMA (1980)

Recent studies have demonstrated problems with the radiodilution assay method for measuring serum cobalamin (vitamin B<sub>12</sub>) levels. We have found the standard commercial radiodilution kit assay to be totally ineffective in screening for cobalamin deficiency. In a four-month period, 352 patients were screened in a routine clinical laboratory using this kit. None of the serum samples yielded a result below the given normal range of 200 to 1,100 pg/mL. However, when 42 patients with low-normal serum cobalamin levels (200 to 500 pg/mL) were retested by a combination of a modified radiodilution kit, a human intrinsic factor assay, and a microbiological (<i>Lactobacillus leichmannii</i>) assay, 16 (36%) were identified as having serum cobalamin levels that were abnormally low. The diagnosis of cobalamin deficiency may have been incorrectly dismissed in many patients on the basis of test results obtained with these kits, which are in widespread use.

Depression may be missed in patients who "normalise" their symptoms
Journal: BMJ (1999)

Adverse prenatal and perinatal factors are associated with schizophrenia of early onsetIn order to investigate the role of prenatal and perinatal risk factors in the development of schizophrenia and affective and reactive psychosis in early adult life, Hultman et al (p 421) carried out three population based, case-control studies using the Swedish birth and inpatient registries.Adverse prenatal and perinatal factors were more common in patients with schizophrenia than in controls and seemed more important in the aetiology of early onset schizophrenia than in affective and reactive psychosis.Multiparity, bleeding during pregnancy, and small size for gestational age were associated with a threefold to fourfold increased risk for schizophrenia among males.The authors conclude that the mechanism underlying the increased risk remains unknown but ischaemic brain damage secondary to placental insufficiency is one possibility.
Intracellular pH regulation in hep G2 cells: Effects of epidermal growth factor, transforming growth factor-?, and insulinlike growth factor-II on Na+/H+ exchange activity*1, *2
Authors: M STRAZZABOSCO
Journal: Hepatology (1995)

Intracellular pH (pHi) plays an important role in the metabolic activation of quiescent cells after a proliferative stimulus, and Na+H+ exchange activity is required for growth in some extrahepatic tumors. To investigate intracellular acid/base homeostasis in hepatoma cells and the effects of putative liver growth factors on Na+H+ exchange activity, we have studied intracellular pH (pHi) regulation in Hep G2 cells, a well-differentiated hepatoma cell line, both in resting conditions and after administration of epidermal growth factor (EGF), transforming growth factor-α (TGFα), and insulinlike growth factor-II (IGF-II). The effects of fetal calf serum, TGFα, and amiloride on 3H-Thymidine incorporation were also studied. Amiloride (1 mmol/L) and external Na+ removal decreased baseline pHi in both HEPES and KRB. In HEPES, cells recovered from an acid load (20 mmol/L NH4C1) by an amiloride inhibitable Na+H+ exchange. In KRB, an additional, DIDS-inhibitable, Na+ and HCO3-dependent, but Cl--independent acid extruder (Na:HCO3 cotransport) was activated. No evidence was found for a Cl/HCO3 exchange acting as acid loader. Administration of EGF and TGFα, but not of IGF-II, induced a dosedependent, amiloride-inhibitable increase in baseline pHi, together with an increase in Na+H+ exchange activity, shifting to the right the JH/pHi curve. Finally, 3Hthymidine incorporation in Hep G2 cells, in the presence of FCS or TGFα, was strongly inhibited by amiloride. In conclusion, in Hep G2 cells, pHi is mainly regulated by Na+H+ exchange, which activity can be stimulated by EGF and TGFα, but not by IGF-II. Administration of TGFα stimulates DNA synthesis, an effect that is blocked by amiloride, an inhibitor of Na+H+ exchanger. These data suggest that Na+H+ exchange activation may play a critical role in the growth of some hepatic tumors.

HIV/AIDS Among Men Who Have Sex With Men and Inject Drugs—United States, 1985-1998
Journal: JAMA (2000)

Men who have sex with men and inject drugs (MSM/IDU) pose unique challenges for human immunodeficiency virus (HIV) risk reduction efforts because they have multiple risks for HIV acquisition and transmission. This report presents 1) the demographic characteristics of MSM/IDU diagnosed with acquired immunodeficiency syndrome (AIDS) in 1998 and MSM/IDU living with AIDS as of December 31, 1998; 2) trends in AIDS incidence among MSM/IDU from 1985 to 1998; and 3) information on selected behaviors from interviews of MSM/IDU who had AIDS diagnosed from 1996 to 1998 in 12 states. The findings indicate that 1) over half of MSM/IDU with AIDS were non-Hispanic blacks and Hispanics, and most MSM/IDU with AIDS were reported from large metropolitan statistical areas (MSAs); 2) AIDS incidence has declined since 1996; and 3) a high prevalence of drug-related and sexual risk behaviors occurred among MSM/IDU with AIDS.
Malignant glioma. Results of combined modality therapy
Authors: J. S. Cooper
Journal: JAMA (1982)

Multimodal treatment of malignant gliomas is routinely used at New York University Medical Center. Overall, our treatment program has resulted in survival rates of 78% at six months, 51% at one year, and 7% at five years for these high-grade brain tumors. However, various subgroups (based on tumor or host factors, or both) fared significantly better or worse than others. Particularly limited survival rates were found in patients who experienced paresis/paralysis or impaired mental function, who had tumors that were markedly anaplastic, who were elderly, or who for a variety of reasons did not receive the multimodal treatment we consider optimal.

Expression and localization of cyclo-oxygenase isoforms in non-small cell lung cancer
Authors: DN Watkins, JC Lenzo, A Segal, MJ Garlepp, PJ Thompson
Journal: European Respiratory Journal (1999)

The beneficial effects of cyclo-oxygenase (COX) inhibitors in both colon cancer and adenomatous polyps suggest a role for the prostanoid pathway in epithelial malignancy. Although variable prostanoid synthesis in non-small cell lung cancer (NSCLC) has been demonstrated in freshly obtained tissue, COX messenger ribonucleic acid (mRNA) and protein localization in such tumours had not been investigated ex vivo. Thirty-four cases of primary NSCLC were examined for both constitutive (COX-1) and inducible COX (COX-2) by means of in situ hybridization and immunohistochemistry. COX-1 mRNA expression was absent or below the level of detection via in situ hybridization. COX-1 immunohistochemistry demonstrated uniform faint cytoplasmic staining in tumour cells and stromal inflammatory cells. Semiquantitative analysis of COX-2 expression in NSCLC demonstrated the highest levels of both mRNA and protein in adenocarcinoma cells (n=10, p&lt;0.005 compared with large cell and squamous cell carcinoma), intermediate and variable expression in large cell carcinoma (n=11) and low or absent expression in squamous cell tumours (n=13). Levels of COX-2 expression in infiltrating inflammatory cells was the same in all tumour types. In conclusion, tumour cell cyclo-oxygenase-2 rather than cyclo-oxygenase-1 expression may account for the variable prostanoid production seen in non-small cell lung cancer, and primary lung adenocarcinoma expresses the highest levels of cyclooxygenase-2. Assessment of cyclo-oxygenase-2 expression ex vivo should be performed in studies examining the potential therapeutic effects of cyclo-oxygenase inhibitors in non-small cell lung cancer.

Beyond willpower
Authors: James J. Gross, Angela L. Duckworth
Journal: Behavioral and Brain Sciences (2021)

Abstract For all its popularity as a psychological construct, willpower is irremediably polysemous. A more helpful construct is self-control , defined as the self-regulation of conflicting impulses. We show how the process model of self-control provides a principled framework for examining how undesirable impulses may be weakened and desirable impulses may be strengthened.
Physical activity and public health
Authors: R. A. Winett
Journal: JAMA (1995)

<h3>To the Editor.</h3> —Exercise promotion has become a major disease prevention goal, but unfortunately, many attempts to have various population segments initiate and maintain exercise and activity have had limited success.<sup>1</sup>Partly in response to disappointing outcomes, and partly based on empirical studies, guidelines for activity and exercise have been reduced to the accumulation of 30 minutes of moderate activity five times per week. While seemingly well-intentioned, these new guidelines and the public health message they deliver may be problematic and potentially counterproductive from both scientific and public policy perspectives in several ways, including: 1. The use of caloric expenditure as a standard. The revised guidelines are partly built around epidemiologic studies showing a relationship between gross measures of caloric expenditure in leisure-time activities and reduced morbidity and mortality.<sup>1</sup>However, the most recent data from the Harvard Alumni Health Study clearly show that what is critical for risk
