Abstract
Echinococcus granulosus sensu lato (E. granulosus s.l.) is a zoonotic parasite, causing cystic echinococcosis in humans. In the present study, prevalence and genotypes of E. granulosus s.l. was assessed in stools collected from 244 dogs including 138 stray and 106 domestic animals using high resolution melting curve (HRM) method. Initially, to detect taeniid eggs in feces, all samples were examined using the formalin-ether techniques. Genomic DNA was extracted from the positive samples and E. granulosus s.l. was differentiated from other Taeniidae parasites using SSU-rDNA gene and E. granulosus s.l. was analyzed for genotyping using HRM based on the cox1 gene. In total, 12.7% (31/244) of the samples were positive for Taeniidae eggs. In addition, among the positive samples, 77.4% (24/31) were positive for E. granulosus s.l.. In details, 11.3% (12/106) of the domestic dogs and 8.7% (12/138) of the stray dogs were positive for E. granulosus s.l.. The results of HRM analysis showed that all E. granulosus s.l. isolates were G1 strain. Findings of the present study indicated a considerable prevalence of E. granulosus G1 among dogs in the northeast of Iran and imply a serious risk of transmitting to humans and livestock.

Abstract
BACKGROUND Recent developments regarding the contribution of microRNAs to tumor angiogenesis and the oncogenic effects of microRNAs point to their potential role in breast cancer angiogenesis. Tumor-derived exosomes are considered a rich source of microRNAs that can regulate the function of other cells in the tumor microenvironment, including vascular endothelial cells. This study analyzes the effect of tamoxifen chemotherapy on the expression of a key microRNA, miR-329, and introduces a regulatory link between this microRNA and the KDM1A gene associated with the vascular endothelial growth factor (VEGF) messaging pathway. MATERIALS AND METHODS MCF-7 breast cancer cells were purchased and cultured in a complete culture medium. These cells were treated with tamoxifen and then their exosomes were extracted from the culture medium. The RNAs of the exosomes were isolated and the expression of miR-329, VEGF, and KDM1A genes in the exosomes was investigated using the real-time polymerase chain reaction (PCR) method. RESULTS The results of this study showed that tamoxifen treatment increased the expression of miR-329 in exosomes derived from MCF-7 cancer cells. The expression of KDM1A and VEGF genes in drug-treated cell exosomes is downregulated. CONCLUSION The results of this experiment demonstrated that the treatment of breast cancer cells with tamoxifen reduces the expression of VEGF and KDM1A by increasing miR-329. The treatment therefore reduces angiogenesis, and thus its anti-tumor effects are applied.

Abstract
BACKGROUND The presented study aimed to gain insights into the pathogenesis of lung cancer (LC) and provide novel bio-markers for LC by building a regulatory circular (circ) RNAmicro (mi) RNAmRNA network. MATERIALS AND METHODS High-throughput sequencing data of circRNAs, miRNAs and mRNAs related to LC originated from GEO (Gene Expression Omnibus) database, and the differential expressions of circRNAs, miRNAs and mRNAs were screened with R language Limma. The circRNA-miRNA and miRNA-mRNA pairs were used to build the ceRNA network. The functions of differential expression circRNAs were elucidated by performing the functional enrichment analysis on GO and KEGG. Furthermore, the selected LC prognostic genes were verified by tissue chips and immunohistochemistry (IHC). RESULTS On the whole, 20 downregulated circRNAs, 55 upregulated miRNAs and 243 downregulated mRNAs were identified in LC. Lastly, a circRNA-miRNA-mRNA ceRNA network was built, which was composed of 2 circRNAs, 2 miRNAs, and 2 mRNAs. As indicated from the analysis based on public databases and IHC, the differential genes (i.e., FXYD1 and SEMA5A) in this network acted as LC prognostic factors. As confirmed by performing IHC and survival analyses, FXYD1 and SEMA5A expressions in LC were downregulated, and their expressions displayed a relationship to the overall survival (OS) of LC cases. CONCLUSIONS This study presents novel insights into the role of circRNAs in the development of LC via the ceRNA mechanism. The identified FXYD1 and SEMA5A gene could act as novel and vital LC prognostic indicators.

Abstract
Amoebiasis has emerged as a major health problem worldwide. It is endemic in the present scenario is different and sub-tropical regions especially in Asia, Latin America and also in Africa. Causative of amoebiasis is a protozoan known as Entamoeba histolytica. We screened all the databases such as PubMed, Science Direct, Medline and Google Scholar by using the keywords ‘anti-Entamoeba histolytica activity of medicinal plants, anti-Entamoeba histolytica activity of herbal drugs, the anti-amoebic activity of natural drugs’. In the present study, we found 7861 articles, where all articles were screened for bias analysis and included 32 full-matching articles in total reporting the use of medicinal plants as a remedy for amoebiasis. Through these articles, we found 42 herbs having anti-amoebic activity. In bias analysis, we also found four articles under high bias risk. In our study, seven medicinal plants were concluded to possess the most potent anti-amoebic activity based on their IC50 value, which was less than 1 μg mL−1. On bias analysis, we found four articles with high bias risk, hence these studies can be repeated for better results.

Abstract
The parasitic diseases represent the most important health risk, especially in underdeveloped countries where they have a deep impact on public health. Trichomoniasis is a prevalent non-viral sexually transmitted disease, and a significant amount of new cases are identified each year globally. Furthermore, the infection is linked with serious concerns such as pregnancy outcomes, infertility, predisposition to cervical and prostate cancer, and increased transmission and acquisition of HIV. The therapy is restricted, adverse effects are often observed, and resistance to the drugs is emerging. Based on this, a new treatment for trichomoniasis is necessary. Natural products represent a rich source of bioactive compounds, and even today, they are used in the search for new drugs. Additionally, natural products provide a wide variety of leadership structures that can be used by the pharmaceutical industry as a template in the development of new drugs that are more effective and have fewer or no undesirable side effects compared to current treatments. This review focuses on the medicinal plants that possess anti-trichomonal activity in vitro or in vivo. An electronic database search was carried out covering the last three decades, i.e., 1990-2020. The literature search revealed that almost a dozen isolated phytoconstituents are being explored globally for their anti-trichomonal activity. Simultaneously, many countries have their own traditional or folk medicine for trichomoniasis that utilizes their native plants, as a whole, or even extracts. This review focuses mainly on the human parasite Trichomonas vaginalis. However, at some points mention is also made to Tritrichomonas foetus that causes trichomoniasis in animals of high veterinary and economical interest. We will focus on the plants and plant-based compounds and their anti-trichomonal activity. The literature search highlighted that there are abundant compounds that possess anti-trichomonal activity; however, in-depth in-vivo evaluation of compounds and their clinical evaluation has not been undertaken. There is a critical need for new anti-trichomonal compounds, and focused research on phytoconstituents can provide the way forward.

Abstract
Abstract
Introduction
Increasing old age and frailty is putting pressure on health services with 5–10% of patients attending the emergency department (ED) and 30% of patients in acute medical units classified as older and frail. National Health Service improvement mandates that by 2020 hospital trusts with type one EDs provide at least 70 hours of acute frailty service each week.
Methodology
A two-week pilot (Monday–Friday 8 am-5 pm) was undertaken, with a “Front Door Frailty Team” comprising a consultant, junior doctor, specialist nurse and pharmacist, with therapy input from the existing ED team. They were based in the ED seeing patients on arrival, referrals from the ED team and patients in the ED observation ward—opposed to the usual pathway of referral from the ED team to medical team. Data was captured using “Cerner” electronic healthcare records. A plan, do, study, act methodology was used throughout with daily debrief and huddle sessions.
Results
95 patients were seen over two weeks. In the over 65 s, average time to be seen was 50 minutes quicker than the ED team over the same period, with reduced admission rate (25.7% vs 46.5%). The wait between decision to admit and departure was shortened by 119 minutes. Overall, this led to patients spending on average 133 minutes less in the ED. 64 patients were discharged, of which 44 had community follow-up (including 37.5% of 64 referred to acute elderly clinic and 25% to rapid response). 47 medications were stopped across 25 patients.
Conclusion
The pilot shows that introduction of an early comprehensive geriatric assessment in the ED can lead to patients being seen sooner, with more timely decisions over their care and reduction in hospital admissions. It allowed for greater provision of acute clinics and community services as well as prompt medication review and real time medication changes.

Abstract
Abstract
Epidemiologic studies and meta-analyses have indicated that metformin is associated with a lower incidence of tumorigenesis among type 2 diabetic patients, including those with head and neck squamous cell carcinoma (HNSCC). HNSCC patients are often treated with concurrent cisplatin-based chemotherapy and radiation (CRT). However, the cure rate remains low at 50% in HPV-negative smokers. Metformin has been shown to inhibit tumor growth and progression, both in vitro and in mouse models, in a wide variety of cancers including HNSCC. The mechanism through which this occurs is thought to be via the inhibition of the mammalian target of rapamycin (mTOR) pathway directly and indirectly through activation of AMPK. Recent studies indicate that increasing the activity of AMPK reduces the expression of PD-L1 found on the surface of cancer cells, thus allowing a greater influx of CD8+ T cells and further activity of NKT cells correlated with increased tumor cell killing. Given the potential antitumorigenic activity of metformin in HNSCC and that biguanide is generally well tolerated compared to other mTOR inhibitors, we hypothesized that the addition of metformin to CRT would be safe and would result in enhanced antitumor responses through activation of AMPK and the immune system. Therefore, in accordance with the phase I open-label, single-site, dose-escalation study combining metformin and CRT in LAHNSCC (NCT02325401), we investigated the effects of metformin on T cells, NK cells, and cytokines from patient PBMCs. Using flow cytometry and cytokine magnetic bead assays (Luminex), we evaluated the immune cell phenotypes and cytokine profiles of peripheral blood in patients before and after metformin treatment on trial. Cytokine profiles were further studied in coculture experiments combining PBMCs, HNSCC cell lines, and metformin. Following metformin treatment, patients developed an increase in activated NK cell populations, determined via NKG2D expression, as well as a shift in their CD8+ T-cell memory phenotypes. Patient serum ELISA examination revealed alterations in cytokine profiles, which were recapitulated in ex vivo experiments. Metformin treatment of HNSCC cell lines in vitro as well as HNSCC PBMCs ex vivo resulted in downregulation of STAT3 compared to healthy controls. Downregulation of STAT3 may be a potential mechanism in which metformin activates NK cells. Here we show evidence that metformin treatment has a direct effect on the innate immune system in patients with LAHNSCC, inducing an antitumorigenic immune response. Our study thus demonstrates that metformin continues to be a good candidate in combination with other therapeutic agents to yield improved clinical outcomes in patients with advanced-stage HNSCC.

Abstract
Abstract
Introduction
2.5 million people in the UK are aged over 80 and up to 50% can be considered frail. Complex co-morbidities and polypharmacy are linked with adverse drug effects and negative outcomes. NICE recommends a medication review yearly, and a hospital admission provides an opportunity for this. STOPP-Frail is a screening tool designed to highlight medications that could be reduced/stopped with a view to improving quality of life. We conducted a quality improvement project to quantify levels of inappropriate prescribing at Croydon University Hospital (CUH), with a view to de-prescribing and reducing adverse drug effects.
Methods
A retrospective analysis was carried out on the Elderly Care wards at CUH. Data was collected from 60 consecutive patients discharged from 1st November 2018, utilising electronic Cerner records. Recorded medication on admission and discharge, noting any amendments in accordance with the STOPP-Frail criteria.
Results
Data collected from 60 patients; one exclusion for not meeting STOPP-Frail criteria (n=59). Median age 86 years (69 to 103 years). Mean number of medications on admission 7.42 (1 to 15). 93.2% patients had polypharmacy (defined as ≥ 4 medications). Mean number of medications on discharge 8.22; an increase of 0.8/patient.
19.4% admission medications met STOPP-Frail criteria for inappropriate prescriptions. Only 18.8% of these were reduced or stopped during admission. Gastrointestinal and cardiovascular medications were most commonly inappropriately prescribed (n=27 and 24 respectively). Most common medications not amended were lipid-lowering therapies (n=21) and proton-pump inhibitors (n= 20).
Conclusions
The opportunity to rationalise medication in the frailest patients admitted to CUH is missed in over 80% of cases. STOPP-Frail provides clear guidance to aid clinicians in reducing inappropriate prescribing. An educational programme is in place to highlight medication rationalisation and guide clinicians in the use of the STOPP-Frail tool. This includes doctors’ induction, departmental teaching, posters and computer flash cards.

Abstract
Toxoplasma gondii is a ubiquitous and infectious parasite that multiplies in any nucleated cell of warm-blooded animals and humans worldwide. This parasite has intricate mechanisms to reciprocate host-cell apoptosis to exist in the host cell. So far, the details of the parasite interactions with host cells are not well known. MicroRNAs (miRNAs) are one of the small noncoding RNAs that are now considered as a key mechanism of gene regulation. They are important in physiological and pathological processes such as apoptosis. In this study a Real Time quantitative PCR technique was used to evaluate the levels of miR-20a of miRNAs family in human macrophage during T. gondii infection to determine the role of miR-20a in apoptosis. Then, the inhibition of miR-20a function through interaction with transfection of Locked Nucleic Acid (LNA) antisense oligomer was studied. Furthermore, it was examined whether miR-20a is involved in apoptosis of human macrophages with T. gondii infected cells using flow cytometry. We found that miR-20a expression is up-regulated in human macrophages following T. gondii infection. After LNA anti miR-20a oligomer transfection, miR-20a inhibition was evaluated by quantitative reverse transcriptase polymerase chain reaction. Flow cytometry results showed that LNA anti-miR20a oligomer increased apoptosis. In agreement with this result, we found that specific LNA oligonucleotides prevent the functional activity of miR-20a and promotion of human macrophages apoptosis with T. gondii infection by inhibition of this miRNAs gene. Also, the results support the concept that LNA oligomer antisense may be used as a therapeutic implement for blocking detrimental miRNAs overexpressed in infections.

Abstract
BACKGROUND Protozoan parasites of the genus Leishmania are etiologic agents which are intracellular pathogens of vertebrates and replicate inside infected macrophages. Leishmania have developed complex strategies to reverse host immune responses in favor of it. One of the major species causing cutaneous involvements is Leishmania major. MicroRNAs (miRNA) are non-coding small RNAs encoding 22-nucleotide (nt) long RNAs. miRNAs affect diverse biological processes, including cell cycle, proliferation, differentiation, growth and development, metabolism, aging, apoptosis, gene expression and immune regulation. This study aimed at evaluating apoptosis and necrosis after transfection locked nucleic acid (LNA) inhibitor of let-7a in the human macrophages miRNAs upon infectionwith L. major. MATERIALS AND METHODS Inhibition of let-7a in macrophages was derived originally from the human monocytes (MDM), using locked nucleic acid (LNA) antagomir. The total cellular RNA was extracted 24 and 48 h post transfection. The levels o Let-7a expression was measured by qPCR Real Time using specific primer. Annexin-V/Propidium Iodide staining method was performed to detect apoptosis and necrosis in the MDM cells. Data were analyzed using the Kruskal-Wallis and Mann-Whitney tests. RESULTS Let-7a inhibition increased the MDM cells apoptosis and necrosis using flow cytometry method. CONCLUSIONS The results suggested that inhibition of let-7a could be a new approach in treatment of leishmaniasis.

Abstract
Echinococcus granulosus, the etiologic agent of echinococcosis, is one of the most important zoonotic helminthes worldwide. Knowledge of E. granulosus species and genotypes has important implications for epidemiology, control, and prevention of diseases as well as future vaccine and drug designs. There are many molecular methods developed to define genotypes of E. granulosus, among them high resolution melting (HRM) analysis, as a new approach, is a single step and closed tube method. It is appropriate for fast screening of large number of isolates. This technique is an accurate, user friendly, cost-effective, fast and simple method, which does not need post-PCR processes. Between March and lst august 2016, of 726 sheep examined in abattoirs in Razavi Khorasan province, Northeast Iran, 109 harboured cystic echincoccosis lesions (liver samples= 65 and lung samples= 44) which were collected for analysis. Total genomic DNA was extracted from each sample and amplified for the presence of polymorphism in the mitochondrial cox1 gene of Echinococcus granulosus using a high resolution melting curve (HRM) method. A total of 109 hydatid cyst samples analyzed by PCR high-resolution melting (qPCR-HRM) curve of the cox1 gene, all isolates were identified as G1 genotype (sheep strain). G1 is the predominant genotype in sheep in northeast of Iran. The high incidence of the G1 genotype (known to be the predominant E. granulosus genotype infecting humans globally) in sheep has considerable implications for hydatid disease control programs in this area.

Abstract
Antimony compounds are first line treatments for cutaneous leishmaniasis. The prognosis of the disease varies depending on the type of medicine and species. We aimed to determine the species responsible for cutaneous leishmaniasis in patients referred to Skin Diseases and Leishmaniasis Research Center in Isfahan and Bam Health Center (Kerman) in order to follow and assess the complete healing of the lesions. A total of 40 skin lesions samples were collected from patients with cutaneous leishmaniasis (CL) form January 2014 to 2015. Dermal scrapings were analyzed by examination of Giemsa-stained smears. Parasites were cultured and isolated in NNN and RPMI 1640 medium and DNA was extracted. We used PCR-RFLP assays of ITS1 genes for direct identification of Leishmania species. Treatment process was assessed after a treatment period with glucantime and healing of the studied cases was followed up. All the samples from Isfahan and Bam regions were L. major and L. tropica species respectively. In patients infected with L. major and L. tropica treated with glucantime, the shortest healing period was 40 days in 5(25%) and 60 days in 3(15.8%) patients, respectively and the longest healing period was 100 days in 1 (5%) and 160 days in 1 (5.3%) patient, respectively. The mean complete healing periods in patients with L. tropica and L. major were 100 and 58 days, respectively (P<0.001). Average recovery period for people with dry cutaneous leishmaniasis is longer than average recovery period for people with wet cutaeous leishmaniasis.

Abstract
Despite the strengths in the Iranian medical and health sciences educational system, areas in need of improvement have been noted. The purpose of this study was to understand the views of faculty members at Shiraz University of Medical Sciences about current and future needs for medical and health sciences education, with the goal of improving the quality of the educational system. The data were collected using a Delphi consensus method. Analysis of the findings identified the following key themes among the factors likely to contribute to medical and health sciences education and training: adding and/or increasing student numbers in higher degrees in preference to associate degrees; providing more interactive, student-centred teaching methods; improving the educational content with more practical and research-based courses tailored to society's needs; and an emphasis on outcome-based student evaluation techniques. These changes aim to respond to health trends in society and enhance the close relationship between medical education and the needs of the Iranian society.

Abstract
Despite the fact that the prognosis of bacterial meningitis has been improved by the influence of antibiotics, this disease is still one of the significant causes of morbidity and mortality in children. Rapid differentiation between bacterial and aseptic meningitis, and the need for immediate antibiotic treatment in the former, is crucial in the prognosis of these patients. Ferritin is one of the most sensitive biochemical markers investigated in cerebrospinal fluid (CSF) for the early diagnosis of bacterial meningitis. The present study aims to evaluate the diagnostic capability of CSF ferritin in differentiating bacterial and viral meningitis in the paediatric setting. A cross-sectional study was carried out in the referral Children's Medical Center Hospital, Tehran, during 2008 and 2009. According to the inclusion criteria, CSF samples from 42 patients with suspected meningitis were obtained and divided into two meningitis groups, bacterial (n = 18) and viral (n = 24). Ferritin and other routine determinants (i.e., leucocytes, protein and glucose) were compared between the two groups. Ferritin concentration in the bacterial meningitis group was 106.39 +/- 86.96 ng/dL, which was considerably higher than in the viral meningitis group (10.17 +/- 14.09, P < 0.001). Mean CSF protein concentration and cell count were significantly higher in the bacterial meningitis group and showed a positive correlation with CSF ferritin. In conclusion, this study suggests that CSF ferritin concentration is an accurate test for the early differentiation of bacterial and aseptic meningitis; however, further investigation on a larger cohort of patients is required to confirm this finding.

Abstract
18169 Background: The cornerstone of treatment in patients with advanced NSCLC is chemotherapy. During past years 3rd generation cytotoxic drugs have replaced 2nd generation drugs in combination with platinum. Although some trials suggest that newer agents are less toxic and with better response rates compared to older ones, but overall survival outcomes are similar. Methods: Between 1999- 2005, 275 patients with advanced NSCLC (unresectable IIIA, IIIB and IV) have been treated in our center with either frontline 2nd (204 pts.) or 3rd (71 pts.) generation, platinum-based regimens. Retrospectively we analyzed the outcome of treatment (i.e. response rate and overall survival) in these patients according to the generation of chemotherapy regimen. Results: Male/female ratio was 3.6/1 and mean age 58.9. Pathology subtypes includes: adenocarcinoma (49.8%), squamous cell carcinoma (28%), undiff. NSCLC (21.8%) and large cell carcinoma (0.4%). The RR was higher with 3rd generation protocols compared to 2nd generations (47.9% vs 26.5%, P = 0.001) but the median OS in both groups was statistically non-significant (12.07 vs 10.57 m). Analyzing RR and OS in different pathology subtypes shows that in adenocarcinoma and squamous cell ca. the RR is higher with 3rd generation compared to 2nd generation (40.5% vs 20%, P=0.01 & 72.8% vs 27.3%, P=0.005 respectively), but the OS between these two generations was not statistically significant in both pathology subtypes. In undiff. NSCLC the outcome between 2nd and 3rd generation is non-significant in terms of OS and RR. The distribution of different stages in both study groups was statistically similar. Conclusions: Based on this study the 3rd generation protocols in the treatment of advanced NSCLC is superior to 2nd generation protocols in term of RR, although the median OS is statistically non-significant. No significant financial relationships to disclose.

Abstract
BACKGROUND Animal exposure may be an important trigger for work-related symptoms among farmers. OBJECTIVE To estimate the prevalence of work-related respiratory symptoms (WRS) in sheep breeders and agricultural farmers and to determine work-related risk factors. METHODS A family doctor used a questionnaire to interview a cohort of 173 farmers comprised of 127 sheep breeders and 46 agricultural farmers in the rural area of Rokh (northeast Iran). The questionnaire pertained to recurrent wheezing, cough, breathlessness or chronic phlegm while at work (these symptoms define WRS), flu-like illness and physician-diagnosed asthma. RESULTS There were 71 subjects (41%) with WRS: 10 of 46 agricultural farmers (21.7%) and 61 of 127 sheep breeders (48.0%). The proportions of sheep breeders with wheezing (16.5%), asthma (14%), cough (29%), breathlessness (31.5%) and flu-like illness (38%) were higher than in agricultural farmers. A significant dose-response relationship among the daily hours worked with animals, the number of animals and the prevalence of symptoms was established for sheep farmers. Sheep shearing and the use of pesticide were associated with an increased risk of wheezing and phlegm. CONCLUSIONS The results suggest that sheep farmers in general have higher rates of work-related symptoms than agricultural farmers. The severity of work-related symptoms will increase with an increase in frequency of animal contact; therefore, these results may underestimate the impact of this exposure.

Abstract
The effects of morphine, 1-aminocyclobutane-cis-1,3-dicarboxylic (ACBD; NMDA agonist) and 3-((R)2-carboxypiperazin-4-yl)-propyl-l-phosphoric acid (CPP; NMDA antagonist) and their concurrent therapy on rat submandibular secretory function were studied. Pure submandibular saliva was collected intraorally by micro polyethylene cannula from anaesthetized rats using pilocarpine as secretagogue. Intraperitoneal injection of morphine (6 mg/kg) induced significant inhibition of salivary flow rate, total protein, calcium, and TGF-beta1 concentrations. Administration of ACBD (10 mg/kg) and CPP (10 mg/kg) alone did not influence secretion of submandibular glands. In combination therapy, coadministration of CPP with morphine did not influence morphine-induced changes in salivary function while ABCD could restore all morphine-induced changes. In combination treatment, ACBD prevented morphine-induced reduction of flow rate, total protein, calcium, and TGF-beta1 and reached control levels. It is concluded that morphine-induced alterations in submandibular gland function are mediated through NMDA receptors.

Abstract
BACKGROUND The effect of ageing on oesophageal motility in patients with achalasia is not well described. Oesophageal contraction amplitude is decreased in otherwise healthy elderly subjects. AIM To evaluate whether ageing influences the motor function of the oesophagus in achalasia. METHODS Initial manometry studies of patients with achalasia were reviewed and findings (lower oesophageal sphincter basal and residual pressures and oesophageal body contraction amplitudes) were compared between two groups of patients, those 65 years of age or older (49 patients) and those younger than 65 years (68 patients). The older group was further divided into those > or =70 years and those <70 years. RESULTS Patients 65 years and older had significantly higher lower oesophageal sphincter basal pressures compared with younger patients (65.6 +/- 4.9 vs. 52.3 +/- 2.7, P = 0.02). At an age cut-off of 70 years, older patients had significantly higher basal (70.7 +/- 1.6 vs. 53.0 +/- 2.4, P = 0.02) and residual (19.7 +/- 1.6 vs. 15.9 +/- 0.7, P = 0.03) lower oesophageal sphincter pressures compared with younger patients. Amplitude of oesophageal contractions was not different between the groups. Across all age groups, there was no linear correlation between age and basal or residual lower oesophageal sphincter pressures (r = 0.28 and 0.12, respectively). CONCLUSIONS Older patients with achalasia have higher lower oesophageal sphincter pressures, however there is no linear correlation between age and lower oesophageal sphincter pressures. Unlike healthy subjects, advanced age is not associated with a decrease in oesophageal contraction amplitude in patients with achalasia.

Abstract
OBJECTIVE Home visitation has been shown to be effective in reducing rates of child maltreatment and in enhancing psychosocial outcomes in children and their parents. Even when available, however, it is underutilized by parents in some urban settings. We tested a supplemental 10-session group intervention for its ability to increase active participation in home visitation, enhance the quality of caregiving behavior of parents, and improve social developmental outcome in children. METHOD A randomized controlled design was utilized, involving two separate cohorts of parents of 3- to 18-month old infants, totaling 148 parent-child dyads. The intervention focused on practical experience in promoting parent-infant attachment relationships. RESULTS At 6 months follow-up, there was a substantial increase in the proportion of intervention group parents participating in home visitation, compared to parents in the control group (Fisher's exact p = .008). Parents in the intervention group exhibited a trend for improvement in their capacity to appropriately interpret infants' emotional cues (p = .08), independent of the effects of home visitation itself. Attrition in both the treatment and control groups was inversely associated with income and level of education. CONCLUSIONS Group meetings may constitute an effective means of engaging stressed urban families in home visitation.

Abstract
Cultured Nb2 node rat lymphoma cells require lactogenic hormone for their proliferation. We reported previously that dexamethasone (Dex) inhibits prolactin (PRL)-induced mitogenesis and, in the absence of mitogen, induces apoptosis of Nb2 cells. Both antiproliferative and cytolytic effects of Dex on Nb2 cells appear to involve glucocorticoid (Type II) receptor mediation. In this study, we compared Dex effects in PRL-dependent Nb2 cells (Nb2) with SFJCD1 (SF), a clone of Nb2 cells that proliferates independently of exogenous PRL. Proliferative assays involved a 72-hr incubation in a chemically defined, serum-free medium where ovine PRL (1 ng/ml) was added to Nb2 cells but not to SF cells. Both cell lines were responsive to the antiproliferative effects of Dex in a dose (6.25-200 nM)-dependent fashion of comparable sensitivity and magnitude. Co-incubation with the glucocorticoid receptor antagonist, RU 486, prevented the antiproliferative effect of Dex in both cell lines. In the same medium devoid of PRL, Dex was cytolytic to Nb2 cells and fragmented DNA in a fashion reflective of apoptosis, but was ineffective in SF cells. A dual chamber incubation system revealed no evidence that SF cells produced cytokines that were mitogenic or anticytolytic to Nb2 cells. Both Nb2 and SF cells fragmented DNA in a fashion indicative of apoptosis in the presence of the Ca2+ ionophore, A23187 (1 microM). These studies reveal a basic difference in glucocorticoid responsiveness between the PRL-dependent Nb2 cell line and its PRL-independent subclone, SF. While both cell lines exhibit functional glucocorticoid receptors and the necessary intranuclear machinery for apoptosis, the pathway mediating the latter is inhibited or dysfunctional in SF cells.
