Household food security in an urban slum: Determinants and trends.

INTRODUCTION: As we are moving from millennium development goals to sustainable development goals, food insecurity is imposing a formidable challenge to the policymakers, especially in developing countries such as India. A survey conducted in the urban slum areas of Vellore district, 6 years back, had reported food insecurity as high as 75%. The current study was a resurvey to assess the food security status in the aforementioned area. MATERIALS AND METHODS: A community-based survey was conducted in which data were collected using a self-administered questionnaire from 150 households, selected through multistaged cluster sampling, who had given oral consent to be a part of the survey. The prevalence of food security calculated from this study was compared with the results from a previous survey to look for any significant improvement. RESULTS: Nearly 42.7% of the households were food secure, while 26.7% were food insecure without hunger and 30.6% were food insecure with some degree of hunger. Low socioeconomic status (odds ratio [OR]: 3.25, 95% confidence interval [CI]: 1.29-8.16; P < 0.012) and presence of debt (OR: 3.84, 95% CI: 1.90-7.73; P < 0.001) were the major risk factors for food insecurity. A comparison with the findings from the previous study has shown a statistically significant improvement in food security from 25.4% to 42.7% (Chi-square: 27.072, df: 2, P < 0.0001). CONCLUSION: Although food security levels have shown marked improvement over the years, much needs to be done for India to be free from the shackles of hunger.

Adsorption mechanisms of L-Glutathione on Au and controlled nano-patterning through Dip Pen Nanolithography.

Dip Pen Nanolithography technique has been employed for patterning L-Glutathione tripeptide (l-y-glutamyl-l-cysteinyl-glycine) nanostructures at specific locations on metallic Au(111) substrate. The formed supramolecular architectures were designed through straight lines and dots serving as precursors for building blocks assemblies in nano-bio-electronics applications or as template structures for functionalized particles in the form of host-guest networks. Tween 20 polyoxyethylene surfactant concentrations ranging from 0.005 to 0.1% (v/v) into initial l-Glutathione tripeptide (2 mg mL(-1)) ink solutions were sequentially tested for the improvement of the ink delivery process and to assure an optimum uniformity and homogeneity over the patterned space. A strong relationship was found between the coated atomic force microscope (AFM) cantilever within the highly effective Tween 20 activator adjuvant and the molecular diffusion along concentration gradients. An increase in the driving force for ink transport from the AFM tip has been demonstrated within the highest 0.1% (v/v) TW 20 surfactant concentration, favoring the patterning of GSH molecules routinely with sub-100 nm resolution. Self-assembled monolayers of GSH were also fabricated and characterized in the light of X-ray photoemission spectroscopy (XPS) and ellipsometric optical measurements. Adsorption from water of l-Glutathione to the gold substrate is proven to be made by the thiol group of cysteine. Theoretical DFT approaches were applied for quantum chemical studies dedicated to electronic processes underneath molecular GSH/Au(111) systems.

The use of topical anesthesia in diagnostic hysteroscopy and endometrial biopsy.

OBJECTIVE: To show that intrauterine anesthesia is a reliable method for reducing pain associated with endocavitary procedures. DESIGN: A prospective, randomized, double-blind study. SETTING: The Department of Obstetrics and Gynecology, Tor Vergata University of Rome, Rome, Italy. PATIENTS: Forty-five patients undergoing diagnostic hysteroscopy (n = 27) or hysteroscopy and endometrial biopsy (n = 18). INTERVENTIONS: Five milliliters of 2% mepivacaine or saline solution were injected transcervically into the uterine cavity before performing the procedures. MAIN OUTCOME MEASURES: Evaluation of pain reduction on a visual analogue scale. RESULTS: Pain expectation and pain reported were reduced during and after the procedures. CONCLUSION: Topical anesthesia effectively reduces pain during hysteroscopy and endometrial biopsy.

Hysteroscopically detected asymptomatic müllerian anomalies. Prevalence and reproductive implications.

OBJECTIVE: To assess the prevalence of uterine anomalies and relative reproductive function in 322 women with abnormal uterine bleeding (AUB) evaluated by diagnostic hysteroscopy. STUDY DESIGN: Uterine contours were classified as septate/bicornuate, arcuate or normal on the basis of hysteroscopy. A complete medical history was obtained from all the subjects; it included a questionnaire on menstrual characteristics, reproductive history and pregnancy outcome. Cumulative birth rates, frequency of spontaneous abortion, preterm delivery, malpresentation and mode of delivery in patients with normal and abnormal uteri were compared using life table analysis, the log-rank test and chi 2 analysis. RESULTS: Arcuate, septate/bicornuate and unicornuate uteri were observed in 6.5%, 3.7% and 0.3% of women, respectively. Although 24-month pregnancy rates and monthly fecundability rates were similar in women with and without müllerian anomalies, the 36-month cumulative live birth rate was significantly lower in women with a septate/bicornuate uterus. Overall, women with uterine malformations showed a significantly higher miscarriage rate (P < .05) and a significantly lower term delivery rate (P < .05) than women with a normal-shaped uterus. CONCLUSION: Diagnostic hysteroscopy in women with AUB detected a 10% prevalence of uterine anomalies, which were associated with a significantly higher incidence of spontaneous abortion and lower cumulative live birth rates.

[Crohn disease in pregnancy. Considerations on and discussion of a clinical case]. / Morbo di Crohn e gravidanza. Considerazioni e discussione su un caso clinico.

Crohn's disease with acute abdomen in pregnancy is described. The Authors evaluate Crohn's disease together with the diagnostic, prognostic and therapeutic problems and relationships between this disease and pregnancy. They conclude as underlining the rarity of Crohn's disease beginning in pregnancy and so the importance of symptoms related to this disease in fertile age woman to make diagnosis and therapy before pregnancy.

[Hysteroscopic evaluation of endometrial ultrasonic anomalies in asymptomatic postmenopausal patients. Preliminary results]. / Valutazione isteroscopica di anomalie ecografiche dell'ecopattern endometriale in pazienti asintomatiche in postmenopausa. Risultati preliminari.

A group of 248 asymptomatic postmenopausal patients was evaluated using transvaginal echography. Thirty-five patients with endometrial echopatterns which were larger than 8 mm and/or irregular then underwent hysteroscopy and endometrial biopsy. Results show that 31.4% of cases in which there was a thickening of the endometrial echopattern correspond to the presence of polyp, myoma, synechia with atrophic endometrium. In conclusion, the Authors affirm the inappropriateness of the term "endometrial echopattern" in menopause, since this term should be reserved to describe the typical appearance of the endometrium during the reproductive phase. They stress that ultrasonography can reveal anomalies of the internal echostructure of the womb but that further tests (e.g. hysteroscopy, biopsy) are required to diagnose their nature.

The miR-17∼92 family regulates the response to Toll-like receptor 9 triggering of CLL cells with unmutated IGHV genes.

Chronic lymphocytic leukemia (CLL) cells from clinically aggressive cases have a greater capacity to respond to external microenvironmental stimuli, including those transduced through Toll-like-receptor-9 (TLR9). Concomitant microRNA and gene expression profiling in purified CLL cells (n=17) expressing either unmutated (UM) or mutated (M) IGHV genes selected microRNAs from the miR-17∼92 family as significantly upregulated and in part responsible for modifications in the gene expression profile of UM CLL cells stimulated with the TLR9 agonist CpG. Notably, the stable and sustained upregulation of miR-17∼92 microRNAs by CpG was preceded by a transient induction of the proto-oncogene MYC. The enforced expression of miR-17, a major member from this family, reduced the expression of the tumor suppressor genes E2F5, TP53INP1, TRIM8 and ZBTB4, and protected cells from serum-free-induced apoptosis (P ≤ 0.05). Consistently, transfection with miR-17∼92 family antagomiRs reduced Bromo-deoxy-uridine incorporation in CpG-stimulated UM CLL cells. Finally, miR-17 expression levels, evaluated in 83 CLL samples, were significantly higher in UM (P=0.03) and ZAP-70(high) (P=0.02) cases. Altogether, these data reveal a role for microRNAs of the miR-17∼92 family in regulating pro-survival and growth-promoting responses of CLL cells to TLR9 triggering. Overall, targeting of this pathway may represent a novel therapeutic option for management of aggressive CLL.

Premorbid sleep, appetite, energy, and cognitive circadian profile in patients with depressive disorders.

AIM: Alterations of biological rhythms are well recognized to play a crucial role in the origin and maintenance of depression, but little is known about the profile of circadian rhythms at a premorbid age in adult depressed patients. The present study was aimed at investigating the association, if any, of depressive disorders with biological and behavioural rhythm modifications both at the time of observation and at an earlier age than the clinical onset of depression. The hypothesis was that such modifications could be an early biological index of vulnerability to the illness. SUBJECTS AND METHODS: One hundred and seventy-eight patients affected by DSM-IV Major Depressive Disorder were examined/observed, compared to a group of 178 matched healthy subjects. All the included subjects were asked to fill in a retrospective questionnaire reporting time of awakening and falling asleep and time of subjective peaks of appetite, energy and cognitive function during "Adolescence" (12-15 years), "Youth" (16-20 years) and "Present condition" periods. RESULTS: An advance of awakening time by about 20 minutes during "Adolescence" was reported in the depressed subjects as compared to the controls. Awakening is also reported as significantly (P<0.001) advanced by about 36 minutes during "Youth" in depressed patients, while time of falling asleep at the same age in the patients group shows 19 minutes delay. Regarding "Present condition" an advance of awakening time (33 minutes) in depressed patients was reported, in association with a delay of the subjective peak of cognitive functioning (62 minutes). DISCUSSION: Depressed patients show clear-cut differences in sleep pattern as compared to controls, consisting in a constant and significant advance of awakening time, while the time of sleep onset never reaches any statistical difference between the groups throughout ages. CONCLUSIONS: The results are consistent with the hypothesis that early alterations of the general circadian profile can contribute to the onset of adult life Major Depressive Disorders.

Exposure of B cell chronic lymphocytic leukemia (B-CLL) cells to nutlin-3 induces a characteristic gene expression profile, which correlates with nutlin-3-mediated cytotoxicity.

By analyzing the cDNA obtained from 16 B-cell chronic lymphocytic leukemia (B-CLL) patient samples, we found that Nutlin-3, a small molecule inhibitor of MDM2/p53 interaction, induced a characteristic gene expression profile (GEP) signature in 13 out of 16 B-CLL samples. The lack of Nutlin-3-induced GEP signature in 3 out of 16 B-CLL samples was not due to p53 deletion and/or mutation, as demonstrated by FISH analysis and p53 sequencing. Of note, the 3 B-CLL samples in which Nutlin-3 did not elicit the GEP signature were also less susceptible to Nutlin-3-mediated cytotoxicity with respect to the remaining 13 B-CLL samples. However, the partial lack of response in these p53 wild-type B-CLL samples was not due to defects in the ability of Nutlin-3 to promote p53 induction, as confirmed by the rapid accumulation of p53 protein at Western blot analysis in response to Nutlin-3 in all samples examined. Upon exposure to Nutlin-3, the genes up-regulated with the highest score in the majority of B-CLL cells were all known p53-target genes, including genes involved in apoptotic pathways, such as FAS and BAX, as well as MDM2. Taken together, our data indicate that the ability of Nutlin-3 to induce a characteristic GEP signature correlates with its cytotoxic potential in p53 wild-type B-CLL cells. However, in some p53 wild-type B-CLL samples, the response to Nutlin-3 cannot be predicted on the basis of FISH analysis or p53 sequencing.

Comparison of two fertility-sparing approaches for bilateral borderline ovarian tumours: a randomized controlled study.

BACKGROUND: During the childbearing years, the standard fertility-sparing treatment for bilateral borderline ovarian tumours (BOTs) is the unilateral oophorectomy plus controlateral cystectomy. The aim of the present study was to compare the effects of two laparoscopic fertility-sparing surgical procedures for the treatment of bilateral BOTs on recurrence and fertility in young women who desire to conceive as soon as possible. METHODS: Thirty-two women affected by bilateral early-stage BOTs who desired to conceive were randomized to receive bilateral cystectomy (experimental group, n=15) or oophorectomy plus controlateral cystectomy (control group, n=17). At the first recurrence after childbearing completion, each patient was treated with non-conservative standard treatment. Recurrences and reproductive events were recorded. RESULTS: After a follow-up period of 81 months (19 inter-quartile; 60-96 range), the cumulative pregnancy rate (CPR) (14/15 versus 9/17; P=0.003) and the cumulative probability of first pregnancy (P= 0.011) were significantly higher in the experimental than in control group. No significant (P=0.358) difference between groups was detected in cumulative probability of first recurrence. CONCLUSIONS: The laparoscopic bilateral cystectomy followed by non-conservative treatment performed at the first recurrence after the childbearing completion is an effective surgical strategy for patients with bilateral early-stage BOTs who desire to conceive as soon as possible.

Ultrasound-assisted laparoscopic cryomyolysis: two- and three-dimensional findings before, during and after treatment.

OBJECTIVE: To investigate the role of two- and three-dimensional (2D and 3D) ultrasound and power Doppler before, during and after surgery in monitoring the effects of uterine fibroid laparoscopic cryomyolysis. METHODS: This prospective study involved 10 premenopausal patients with a sonographic diagnosis of a single subserosal and/or intramural uterine myoma, who underwent laparoscopic cryomyolysis. All patients suffered from symptoms due to fibroids (menometrorrhagia, bulk-related symptoms, pelvic pain). During laparoscopy transvaginal sonography was performed to guide the insertion of the cryoprobe, monitor extension of the ice-ball and evaluate the reduction of the blood supply of the myoma. All patients underwent 2D and 3D sonographic and power Doppler imaging evaluation of the myoma 1 week before treatment, during cryomyolysis, and 1, 3 and 6 months after treatment; size, echostructure and vascularization were recorded. RESULTS: With cryomyolysis, we achieved selective vessel and tissue damage within the fibroid alone. Eight patients were free of symptoms and two had improved after 3 months. Progressive shrinkage of the treated myoma was observed during follow-up with a reduction percentage after 1 month of 22.2%, after 3 months of 37.5% and after 6 months of 52.6%. After cryomyolysis a significant reduction in central blood flow of the myoma was observed. 2D and 3D power Doppler evaluation of vascularization did not differ although subjectively findings were best evaluated by 3D images. CONCLUSION: Sonography can aid the safe accomplishment of cryomyolysis by assessing myomata preoperatively, guiding the freezing procedure during laparoscopy, and helping to monitor postoperative progress. The use of ultrasound in this new treatment of fibroids will permit the physician to modulate and individualize treatment.

Site and menstrual cycle-dependent expression of proteins of the tumour necrosis factor (TNF) receptor family, and BCL-2 oncoprotein and phase-specific production of TNF alpha in human endometrium.

Apoptosis in human endometrial epithelium progressively increases from early to late secretory/menstrual phases and remains consistently more prominent in the basalis. It has been suggested that tumour necrosis factor (TNF) alpha secreted during the secretory/menstrual phases plays a role in induction of programmed cell death in these cells. In the present study, we characterized expression of receptors of TNF alpha, Fas antigen and BCL-2 in endometrial cells to gain insight as to whether this type of cell death in endometrium may be related to differential or preferential expression of these proteins at specific phases of the menstrual cycle. In addition, to relate production of TNF alpha to the development of apoptosis, the amount of TNF alpha released by human endometrium was measured. Immunostaining demonstrated that the TNF receptor (TNFr; p55/60)-I, TNFr-II (p75/80) as well as Fas protein were expressed in endometrial epithelium throughout the entire menstrual cycle. This expression was progressively diminished from the basalis towards the upper functionalis. In the proliferative phase, the expression of BCL-2 was prominent in the endometrial glands particularly in those residing in the basalis. This expression became weak as early as the third post-ovulatory day and remained low during the remaining phases of the menstrual cycle. The amount of TNF alpha released by endometrial fragments obtained from various phases of the menstrual cycle was determined. The amount of TNF alpha released into the culture medium by the endometrium was low in the proliferative phase. However, the amount of released TNF alpha progressively increased in the secretory phase and peaked in the menstrual phase. TNFr-I, TNFr-II, Fas, BCL-2 and TNF alpha could be identified by Western blot analysis of proteins extracted from endometrium. Therefore, endometrial epithelium by virtue of expression of receptors of TNF alpha as well as Fas protein is properly poised to respond to ligand signals that regulate apoptosis. Induction of apoptosis in endometrial epithelium and menstrual shedding may be related to loss of the protective effect of BCL-2 as well as to the amount of TNF alpha.

Is local anesthesia an affordable alternative to general anesthesia for minilaparoscopy?

STUDY OBJECTIVE: To determine if minilaparoscopy under local anesthesia is at least as reliable and affordable as that performed under general anesthesia. DESIGN: Prospective, randomized study (Canadian Task Force classification I). SETTING: University-affiliated hospital. PATIENTS: One hundred sixty-four consecutive women evaluated for infertility. INTERVENTION: Diagnostic minilaparoscopy performed after women were randomized to receive general or local anesthesia with conscious sedation. MEASUREMENTS AND MAIN RESULTS: Levels of postoperative pain measured by visual analog scale; volume of CO(2) used; length of procedure, complete pelvic evaluation, and hospitalization; complications; and pathologic diagnosis were evaluated. The groups were comparable in age, years of infertility, and symptoms. For women receiving local anesthesia, 5.5% required general anesthesia to complete the procedure. Women in both groups required postoperative analgesics. The groups had no statistically significant differences in pain level 1 hour after the procedure, number of complications, and pelvic pathology. Patients who had local anesthesia required a smaller volume of CO(2) (p <0.01) and their hospitalization was significantly shorter (p <0.01). However, in 15% of these women pelvic visualization was incomplete, compared with 7.2% in the general anesthesia group. CONCLUSION: Minilaparoscopy performed under local anesthesia was as reliable and affordable as when performed under general anesthesia.

Ultrasonographic prediction of the efficacy of GnRH agonist therapy before laparoscopic myomectomy.

STUDY OBJECTIVE: To assess ultrasonographic prediction of the efficacy of administration of a gonadotropin-releasing hormone (GnRH) analog before laparoscopic myomectomy. DESIGN: Prospective, randomized study of women treated consecutively from September 1994 to July 1996 (Canadian Task Force classification I). SETTING: Endogyn Service, Private Endoscopic Associates, Naples, and Department of Gynecologic and Pediatric Sciences, Reggio Calabria University, Catanzaro, Italy. PATIENTS: Sixty-seven infertile women with symptomatic uterine myomata, mainly intramural, undergoing laparoscopic myomectomy. INTERVENTIONS: Patients were prospectively randomized in two groups. Group A received preoperative administration of two injections of a depot formulation of leuprolide acetate 28 days apart, and group B underwent direct surgery. In each group we studied the number, diameter, and echogenicity of larger fibroids; resistance index of uterine arteries and myoma vessels; operating time; and blood loss. MEASUREMENTS AND MAIN RESULTS: The two groups did not significantly differ in baseline ultrasonographic parameters. Both blood loss (p <0.01) and operating time (p <0.05) were significantly lower in group A. However, operating time was significantly longer when the main myoma was markedly hypoechoic. CONCLUSION: Our data confirm the therapeutic efficacy of administration of a GnRH analog before laparoscopic myomectomy in reducing blood loss and decreasing operating time in all cases except those with markedly hypoechoic fibroids.

Outpatient diagnostic hysteroscopy.

STUDY OBJECTIVE: To evaluate the feasibility, validity, indications, and results of a large series of diagnostic hysteroscopies performed without anesthesia. DESIGN: Retrospective analysis of hysteroscopy charts performed between 1989 and 1996 (Canadian Task Force classification II-2). SETTING: University-affiliated endoscopy unit. PATIENTS: Four thousand consecutive women referred for different indications. INTERVENTIONS: Diagnostic hysteroscopy was performed in 91% of patients without premedication or anesthetics. In some women premedication or general or local anesthesia was required to access the uterine cavity. MEASUREMENTS AND MAIN RESULTS: The success rate, validity indication, complication rate, and number of biopsies were critically evaluated and assessed in relation to increased experience of operators. In 91% of women we accessed the uterine cavity at the first attempt without premedication, whereas 207 (5. 1%) patients required local anesthesia and 99 (2.4%) premedication. Only 1.6% required general anesthesia. In 52% intrauterine pathology was diagnosed and in 21% further surgical treatment was suggested. CONCLUSION: Hysteroscopy was feasible when performed in an outpatient setting without general or local anesthesia in more than 90% of women. The operator's experience seems a key factor both for accurate endometrial evaluation and to reduce failure and endometrial biopsy rates. The low frequency of further surgical treatment justifies performing the procedure in the office.

Pain mapping during minilaparoscopy in infertile patients without pathology.

STUDY OBJECTIVE: To draw a map of pelvic pain and quantify the level of provoked pain during minilaparoscopy under local anesthesia and conscious sedation. DESIGN: Observational study (Canadian Task Force classification II-2). SETTING: University hospital. PATIENTS: Twenty infertile women. INTERVENTIONS: Minilaparoscopy was performed under local anesthesia and conscious sedation, and cognitive performance was evaluated with the Rey auditory verbal learning task. MEASUREMENTS AND MAIN RESULTS: The diagnostic procedure was performed with one 2-mm micrograsper and one 2-mm microprobe to evaluate the pelvis. In particular we grasped utero-ovarian ligaments; we touched, grasped, and distended fallopian tubes with blue dye; we moved the uterus with a manipulator inserted at the cervix; and we touched and grasped bowel and omentum. Level of pain was recorded on a visual analog scale. Patients had no pathologic findings, including minimal endometriosis and pelvic adhesions. The highest level of pain was recorded when we distended the tubes. No pain was elicited when we touched and grasped ovary, omentum, and bowel. In 10% of women when we stretched the tubo-ovarian ligament we provoked a minimal vagal reaction. CONCLUSION: Minilaparoscopy under conscious sedation for pelvic pain mapping in women without pain or pathology revealed consistently negative findings, validating the value of this measurement.

Pain control after microlaparoscopy.

STUDY OBJECTIVE: To evaluate the efficacy of intraperitoneal subdiaphragmatic instillation of 0.5% lidocaine and 0.5% bupivacaine infiltration of cannula sites to control pain after diagnostic microlaparoscopy. DESIGN: Prospective, randomized study. (Canadian Task Force classification I). SETTING: Day surgery unit of Endogyn Service, Private Endoscopic Associates, Naples, and Department of Gynecologic and Pediatric Sciences, Reggio Calabria University, Catanzaro, Italy. PATIENTS: Forty women treated for infertility. INTERVENTIONS: The treated group received 0.5% intraperitoneal subdiaphragmatic lidocaine 40 ml and 0.5% bupivacaine 5 ml infiltration of cannula insertion sites. The control group received no treatment. In all patients the procedure was performed with atropine 0.5 mg, fentanyl 0.1 mg, droperidol 5 mg, and local anesthesia. Postoperatively, depending on the need, ketoprofene 100 mg or ketorolac 30 mg was administered intramuscularly. MEASUREMENTS AND MAIN RESULTS: Postoperative pain score was evaluated by visual analog scale immediately postoperatively and 1, 3, 6, 12, 24, 36, and 48 hours afterward. The treated group had significantly lower pain scores at the end of surgery and at 1-, 3-, (p <0.01), and 6-hour intervals (p <0.05). No significant differences in scores between groups were observed starting from 6 hours postoperatively. CONCLUSION: Postoperative intraperitoneal lidocaine and bupivacaine infiltration of cannula sites offered a detectable benefit to women undergoing diagnostic microlaparoscopy. The effect was temporary, but induced a significant decrease in the postoperative pain for approximately 6 hours.

Hysteroscopic findings in 344 women with recurrent spontaneous abortion.

STUDY OBJECTIVE: To evaluate the prevalence of different anatomic factors in women with recurrent spontaneous abortion (RSA). DESIGN: Retrospective analysis over 9 years (Canadian Task Force classification II-2). SETTING: University hospital-affiliated endoscopic unit. PATIENTS: Three hundred forty-four consecutive patients with RSA and 922 controls referred for abnormal uterine bleeding. INTERVENTION: Diagnostic hysteroscopy. MEASUREMENTS AND MAIN RESULTS: Major and minor uterine mullerian abnormalities (septate, unicornuate uteri) were found significantly more often in women with RSA than in controls (32% vs 6%, p <0.001). The frequency of acquired uterine anomalies (submucous myomas, polyps) was significantly higher in controls (32% vs 9%, p <0.001). No significant differences were observed between groups in frequency of adhesions (4% vs 2%). CONCLUSION: Major mullerian uterine abnormalities are associated with RSA, and minor uterine anomalies may be correlated with an increased risk of recurrent miscarriage.
