RESUMO
OBJECTIVES: To assess access to abortion pills offered by clinics providing state-funded family planning services in California. METHODS: We attempted to make two scripted calls to a 20% random sample of family planning clinics in California, stratified by county, as "secret shoppers" in 2020 and 2021. RESULTS: Clinic staff responded to 407 calls. Only 50 respondents (12%) reported their clinic offered abortion pills and 23 respondents (6%) accurately indicated to callers that abortion pills were available free to low-income individuals in California. Most (68%) clinics that did not offer abortion pills could not direct callers to a clinic that did offer abortion pills. CONCLUSIONS: Efforts are needed to increase the number of clinics providing medication abortion services in California. Clinic staff need training to provide accurate information about medication abortion.

Background The annual Ashura pilgrimage is a mass Islamic gathering during which millions of worshippers converge in the city of Karbala in Iraq. We report on the incidence of the coronavirus disease 2019 (COVID-19) in Omani pilgrims returning from Karbala in the month of Muharram (August) 2021 during the COVID-19 pandemic. Methodology This is a retrospective study using an electronic, self-completed, and Arab-language survey, composed of 17 questions, that was distributed to all pilgrims returning from Karbala. Participation was voluntary, and consent with confidentiality was obtained. Data on the demographics including sex, COVID-19 vaccination record, type of vaccine, duration of stay, compliance with wearing a face mask, using hand sanitization, and polymerase chain reaction (PCR) results for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) virus before the departure from Oman, upon the return to Oman, and on the eighth post-quarantine day were collected. The responses were collected from the period between August 28, 2021, and September 25, 2022. Statistical association and analysis were performed using the Statistical Package for Social Sciences (SPSS) software (IBM SPSS Statistics, Armonk, NY). Results Out of 250 pilgrims, 139 responded to the survey. Fifty-two participants (37.4%) were males, and 87 (63.6%) were females. None of the pilgrims had positive SARS-CoV-2 PCR results before their departure from Oman. Only four pilgrims (2.9%) were detected positive on PCR by the end of a compulsory quarantine on the eighth day after arrival to Oman. No hospital admissions were recorded. The vast majority of the pilgrims were vaccinated with two doses of COVID-19 vaccination, while some few pilgrims were not vaccinated at all. Most of the pilgrims were also compliant with mask wearing, and just over half the pilgrims were compliant with hand sanitization. No significant statistical association was found between contracting SARS-CoV-2 virus infection and taking SARS-CoV-2 vaccination, the number of vaccination doses, having had COVID-19 before, wearing a mask, or compliance with hand sanitization. Conclusion The incidence of COVID-19 cases among pilgrims returning from Iraq during the COVID-19 pandemic was low. No significant difference was noted between pilgrims vaccinated and compliant with the protective measures and those who were not vaccinated or compliant. Herd immunity could be a possible explanation for the low incidence of COVID-19 infection. Larger studies are needed to investigate the incidence of COVID-19 in Ashura pilgrims.
RESUMO
BACKGROUND: Head and neck cancer (HNC) patients are often challenged by treatment induced dysphagia and trismus. Traditionally, rehabilitation is initiated when loss of function has already occurred. There is increasing evidence that it is of benefit to patients to initiate an early rehabilitation process before and during treatment. HNC patients have a unique set of functional challenges such as pre- and post-treatment dysphagia, pain and weight loss. The aim of the trial is to investigate the effects of swallowing and mouth-opening exercises combined with progressive resistance training (PRT) during radiotherapy. This report presents the protocol, interim inclusion and feasibility data. MATERIAL AND METHODS: The trial (clinicaltrials.gov NCT02385929) is a multicenter randomized controlled trial (RCT) with a parallel-group randomization (1:1). The planned sample size of 240 HNC patients is randomly assigned to either (1) twice weekly PRT and three times weekly swallowing exercises by physio- and occupational therapists, respectively, as well as daily home exercises throughout radiotherapy or (2) standard care. Inclusion criteria are patients with cancer in the larynx, pharynx, oral cavity, or unknown primary tumor who are referred to radiotherapy with curative intent. Outcomes are measured at end-of-treatment and two, five, and 12 months post-treatment. Interim results: In 16 months, 321 HNC patients were screened for eligibility. Of these, 131 (41%) were eligible according to inclusion criteria. One-hundred-and-fifteen patients were invited to participate of which 69 (60%) were enrolled in the trial and randomized for either intervention or control group with 10 drop-outs (14%). The six pilot patients adhered more than 90% to the program. CONCLUSION: Preliminary results show that exercise according to protocol is tolerable and feasible.

Kava (Piper methysticum) is a plant-based medicine, which has been previously shown to reduce anxiety. To date, however, no placebo-controlled trial assessing kava in the treatment of generalized anxiety disorder (GAD) has been completed. A total of 75 participants with GAD and no comorbid mood disorder were enrolled in a 6-week double-blind trial of an aqueous extract of kava (120/240 mg of kavalactones per day depending on response) versus placebo. γ-Aminobutyric acid (GABA) and noradrenaline transporter polymorphisms were also analyzed as potential pharmacogenetic markers of response. Reduction in anxiety was measured using the Hamilton Anxiety Rating Scale (HAMA) as the primary outcome. Intention-to-treat analysis was performed on 58 participants who met inclusion criteria after an initial 1 week placebo run-in phase. Results revealed a significant reduction in anxiety for the kava group compared with the placebo group with a moderate effect size (P = 0.046, Cohen d = 0.62). Among participants with moderate to severe Diagnostic and Statistical Manual of Mental Disorders-diagnosed GAD, this effect was larger (P = 0.02; d = 0.82). At conclusion of the controlled phase, 26% of the kava group were classified as remitted (HAMA ≤ 7) compared with 6% of the placebo group (P = 0.04). Within the kava group, GABA transporter polymorphisms rs2601126 (P = 0.021) and rs2697153 (P = 0.046) were associated with HAMA reduction. Kava was well tolerated, and aside from more headaches reported in the kava group (P = 0.05), no other significant differences between groups occurred for any other adverse effects, nor for liver function tests. Standardized kava may be a moderately effective short-term option for the treatment of GAD. Furthermore, specific GABA transporter polymorphisms appear to potentially modify anxiolytic response to kava.

Patients with ESCC (squamous cell carcinoma of the esophagus) are most commonly diagnosed with locally advanced tumor stages. Early metastatic disease and late diagnosis are common reasons responsible for this tumor's poor clinical outcome. The prognosis of esophageal cancer is very poor because patients usually do not have symptoms in early disease stages. Squamous cell carcinoma of the esophagus frequently complicates patients with multiple co-morbidities and these patients often require interdisciplinary diagnosis and treatment procedures. At present time, neoadjuvant radiation therapy and chemotherapy followed by surgery are regarded as the international standard of care. Meta-analyses have confirmed that this approach provides the patient with better local tumor control and an increased overall survival rate. It is recommended that patients with positive tumor response to neoadjuvant therapy and who are poor surgical candidates should consider definitive radiochemotherapy without surgery as a treatment option. In future, EGFR antibodies may also be administered to patients during therapy to improve the current treatment effectiveness. Positron-emission tomography proves to be an early response-imaging tool used to evaluate the effect of the neoadjuvant therapy and could be used as a predictive factor for the survival rate in ESCC. The percentage proportions of residual tumor cells in the histopathological analyses represent a gold standard for evaluating the response rate to radiochemotherapy. In the future, early response evaluation and molecular biological tests could be important diagnostic tools in influencing the treatment decisions of ESCC patients.

An experiment was carried out under plastic house conditions to compare the effect of four fermented organic matter sources (cattle, poultry and sheep manure in addition to 1:1:1 mixture of the three organic matter sources) in which 4 kg organic matter m(-2) were used, with that of the conventional agriculture (chemical fertilizers) treatments on Marvello red pepper fruit quality, by using a Randomized Complete Block Design (RCBD) with four replicates. Pepper fruits characteristics cultivated in soil supplemented with manure were generally better than those from plants grown in soil only. Addition of animal manure increased bell pepper fruit content of soluble solids, ascorbic acid, total phenols, crude fibre and intensity of red color as compare with conventional agriculture that produced fruits with higher titratable acidity, water content, lycopene and bigger fruit size. In most cases of animal manure treatments, best results were obtained by the sheep manure treatment that produced the highest TSS, while the worst results were obtained by the poultry manure treatment that produced the smallest fruit and lowest fruit lycopene content.

Sinusoidal entry is the first obligatory process preceding intracellular drug removal in liver. Transport of the angiotensin converting enzyme inhibitor enalapril (1-750 microM with [(3)H]enalapril), a substrate of Oatp1, the sodium-independent organic anion transporting polypeptide 1 cloned from rat liver, was studied in rat hepatocytes isolated from all zones of the liver (homogeneous) and from enriched periportal (PP) and perivenous (PV) hepatocytes prepared by collagenase perfusion and zone-selective destruction with digitonin, respectively. Uptake was linear over 1 min and was concentration-dependent. Transport by the homogeneous hepatocytes (in the presence and absence of Na(+)) and PP and PV cells was described by single saturable components of similar kinetic constants (K(m) values of 344-461 microM and V(max) values of 9.5-11.6 nmol/min/10(6) cells; P >.05, ANOVA). The K(m) value for enalapril uptake in hepatocytes was of the same order of magnitude compared with that for Oatp1 expressed in HeLa cells transfected with cDNA-Oatp1 and Western blot analysis revealed similar levels of immunoreactive Oatp1 expression in PP and PV hepatocytes. However, enalapril was not taken up by Oatp2 nor by the human OATP expressed in recombinant vaccinia systems.

Previous studies showed that the transport of enalapril occurred homogeneously among zonal rat hepatocytes. However, the metabolism of hepatic arterially delivered enalapril, swept into the rat liver by the portal or hepatic venous flow (HAPV and HAHV perfusion), was more abundant in the perivenous (PV) than the periportal (PP) region. Hence, metabolic activities toward enalapril in 9000g supernatant (S9) fractions of enriched rat PP and PV hepatocytes were examined. Although Michaelis-Menten kinetics were invariably observed, the metabolic activity toward enalapril (intrinsic clearance or V(max)(met)/K(m)(met) of 0.008 ml/min/mg of S9 protein, V(max)(met) of 21 +/- 6 nmol/min/mg of S9 protein, and K(m)(met) of 2612 +/- 236 microM) was greater in PV than in PP (V(max)(met) of 5.5 +/- 3.1 nmol/min/mg of S9 protein and K(m)(met) of 1049 +/- 335 microM; intrinsic clearance of 0.0052 ml/min/mg of S9 protein) hepatocytes. These metabolic intrinsic clearances were much lower than the sinusoidal influx clearances observed from previous transport studies, revealing metabolism as the rate-limiting step. Substitution of the scaled-up transport and metabolic intrinsic clearances into the "well stirred", "parallel-tube", and "dispersion" models predicted higher steady-state extraction ratios for HAHV perfusion. By contrast, integration of the scaled-up in vitro parameters on zonal metabolism and homogeneous transport into a "zonal-compartment" model of three zonal subcompartments (1, 2, and 3) provided an improved description of the extraction ratios during HAPV and HAHV. Zonal factors are important for the scale-up of data in vitro to the whole organ.

A specific and saturable interaction between 125I-gastrin and eosinophils was discovered in autoradiographs of human gastric mucosal tissue and confirmed in isolated and enriched preparations of WBC's. Gastrin displaced 125I-gastrin from eosinophils in a dose-dependent manner with a D50 = 11 uM. Scatchard analysis of the saturation curve indicated a single binding site of low affinity (Kd = 4.14 uM) and high capacity (Bmax = 430 umoles/mg protein). The gastrin binding protein was localized to the granular core of the eosinophil and found to have a molecular weight of approximately 15 kDa following chemical crosslinking of radioligand to granules and SDS/PAGE. Based on its molecular weight and granular location and the charge characteristics of gastrin, the gastrin binding protein in the human eosinophil is most likely major basic protein. In vivo this interaction might act to limit the cytotoxic potential of MBP on tissues and/or attentuate gastrin concentrations thereby helping regulate gastric acid secretion and mucosal growth.

In the present study, the role of thiols on glyceryl trinitrate (GTN) induced relaxation of rabbit taenia coli strips (RTCS) was investigated. This study was designed to test the hypothesis that a deficiency in thiols is responsible for RTCS insensitivity to GTN, and thus thiols play a key role in the enzymatic activation of GTN. Isolated RTCS bathed in normothermic, oxygenated Krebs solution were pretreated with the thiols L-cysteine (5 mM) and N-acetyl-L-cysteine (NAC, 5 mM) for 30 min and washed. The effects of GTN were determined by changes in isometric tension of K(+)-precontracted RTCS. Both L-cysteine and NAC resulted in increased relaxations to GTN (0.1 nM-10 microM) as the GTN relaxation EC50 decreased compared with that of the untreated RTCS (L-cysteine, 0.06 +/- 0.12 microM and NAC, 0.08 +/- 0.03 microM versus control 0.25 +/- 0.08 microM, n = 5, p < 0.05). In contrast, 5 mM D-cysteine had no significant effects on the RTCS GTN relaxation EC50 (0.16 +/- 0.13 microM, n = 5). Similarly, the thiol donor L-methionine significantly increased RTCS sensitivity to GTN, as the relaxation EC50 decreased from the control value of 0.25 +/- 0.08 microM to 10 +/- 4 nM (n = 5, p < 0.001), whereas the D-isomer did not. These results are consistent with the idea that thiols play a key stereospecific role in the metabolic activation of GTN in RTCS. However, RTCS treated with amino acids were still less sensitive to GTN compared with vascular tissue, and this suggests that RTCS may be deficient in some other enzyme(s) relative to vascular tissue that is (are) responsible for the activation of GTN.
