Pathological conditions of the sentinel bivalve, the little mussel Brachidontes rodriguezii, from contaminated intertidal sites in the Southwestern Atlantic coast. J Invertebr Pathol 2021; 184:107654. [PMID: 34389406 DOI: 10.1016/j.jip.2021.107654] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/10/2020] [Revised: 07/02/2021] [Accepted: 08/06/2021] [Indexed: 11/16/2022]
Abstract
A survey of pathological conditions affecting the natural beds of the dominant bivalve species of the intertidal rocky coasts of the Southern Atlantic Ocean, was performed. Samples of the little mussel (n = 992), Brachidontes rodriguezii, which is considered a sentinel species, were collected from seven sites that present different anthropogenic activity (low anthropogenic activity, harbor, and sewage waste) along the Argentinean coast, and processed by standard histological techniques. Our results showed for the first time in a B. rodriguezii population from Mar del Plata harbor a bacterium causing cellular lysis of the spermatogenic cells (6.5% of prevalence) and in a population from Villa Gesell, a site with low anthropogenic activity, one little mussel presented cytoplasmic vacuoles in the oocytes's cytoplasm similar to a microsporidian (0.2% of prevalence). A ciliated protozoan parasitizing the cytoplasm of the epithelial digestive tubules and larval stages of two different digenean parasites, was found infecting the little mussel from both contaminated and uncontaminated sites. Sporocysts of the family Bucephalidae invaded the gonad, causing severe gonadal damage including castration, and gymnophallid metacercariae located between the mantle and shell or embedded in the mantle tissues, occupied the gonadal space. In Punta Carballido, a site located next to a sewage outfall, the highest prevalence of infection was found, for the ciliated protozoan in the digestive tubules (5.1%) and for the digenean parasites (bucephalid sporocyst 24.4%, and gymnophallid metacercariae 50%). Moreover, we found a positive correlation between shell length and overall prevalence of parasites.

Chiggers (Acariformes: Trombiculoidea) do not increase rates of infection by Batrachochytrium dendrobatidis fungus in the endemic Dwarf Mexican Treefrog Tlalocohyla smithii (Anura: Hylidae). Int J Parasitol Parasites Wildl 2020; 11:163-173.

Abstract
Amphibian populations are globally declining at an alarming rate, and infectious diseases are among the main causes of their decline. Two micro-parasites, the fungus Batrachochytrium dendrobatidis (Bd) and the virus Ranavirus (RV) have caused mass mortality of amphibians and population declines. Other, less understood epizootics are caused by macro-parasites, such as Trombiculoidea chiggers. Infection with chiggers can affect frog behavior and survival. Furthermore, synergistic effects of co-infection with both macro and micro-parasites may lead to higher morbidity. To better understand these potential synergies, we investigated the presence and co-infection by chiggers, Bd and RV in the endemic frog Tlalocohyla smithii (T. smithii). Co-infection of Bd, RV, and/or chiggers is expected in habitats that are suitable for their co-occurrence; and if infection with one parasite facilitates infection with the others. On the other hand, co-infection could decrease if these parasites were to differ in their micro-environmental requirements (i.e. niche apportionment). A total of 116 frogs of T. smithii were studied during 2014 and 2016 in three streams within the Chamela-Cuixmala Biosphere Reserve in Jalisco, Mexico. Our results show that 31% of the frogs were infected with Trombiculoidea chiggers (Hannemania sp. and Eutrombicula alfreddugesi); Hannemania prevalence increased with air temperature and decreased in sites with high canopies and with water pH values above 8.5 and below 6.7. Bd prevalence was 2.6%, RV prevalence was 0%, and none of the frogs infected with chiggers were co-infected with Bd. Together, this study suggests that chiggers do not facilitate infection with Bd, as these are apportioned in different micro-habitats. Nevertheless, the statistical power to assure this is low. We recommend further epidemiological monitoring of multiple parasites in different geographical locations in order to provide insight on the true hazards, risks and conservation options for amphibian populations.

Abstract
This study examines, for the first time, the effect of hybrid Elaeis oleifera × E. guineensis palm oil supplementation on human plasma lipids related to CVD risk factors. One hundred sixty eligible participants were randomized and assigned to one of the two treatments: 25 mL hybrid palm oil (HPO group) or 25 mL extra virgin olive oil (EVOO group) daily for 3 months. Fasting venous samples were obtained at baseline and after 1, 2 and 3 months for measurement of plasma lipids (TC, LDL-C, HDL-C and TAGs). Changes in body mass index and waist circumference were also assessed. Although there was an overall reduction in TC (7.4%, p < 0.001) and in LDL-C (15.6%, p < 0.001), no significant differences were found between the treatment groups in a repeated measures analysis of variance for TC (p = 0.0525), LDL-C (p = 0.2356), HDL-C (p = 0.8293) or TAGs (p = 0.3749). Furthermore, HPO consumption had similar effects on plasma lipids to EVOO, thus providing additional support for the concept that hybrid Elaeis oleifera × E. guineensis palm oil can be seen as a "tropical equivalent of olive oil".

Abstract
The effects of cyclopentyl methyl ether (CPME) addition during the aqueous xylose dehydration reaction to furfural are reported here. These investigations were conducted by using pure xylose and Cynara cardunculus (cardoon) lignocellulose as sugar source and H(2)SO(4) as catalyst. The research was also applied to aqueous solutions containing NaCl, since it has been previously demonstrated that NaCl incorporation to these reaction mixtures remarkably increases the furfural formation rate. It has been found that CPME incorporation inhibits the formation of undesired products (resins, condensation products and humins). Thus, cardoon lignocellulosic pentoses were selectively transformed into furfural (near 100%) at the following reaction conditions: 1 wt.% H(2)SO(4), 4 wt.% biomass referred to aqueous solution, 30 min reaction, 443 K, CPME/aqueous phase mass ratio equals to 2.33, and NaCl/aqueous solution mass ratio of 0.4. In contrast, no effect was observed for cellulosic glucose transformation into hydroxymethylfurfural and levulinic acid at identical reaction conditions.

Abstract
INTRODUCTION Adolescence is a critical period for the acquisition and configuration of healthy dietary habits and lifestyle for the young future, which will likely persist throughout the adulthood. Paediatric and juvenile obesity is a public health problem which control necessarily implies prevention and nutritional education. OBJECTIVES To evaluate the nutritional status of the adolescents and determine the proportion with overweight or obesity, and to establish a Nutritional Intervention Programme and analyse the improvement in the pattern of dietary habits among the adolescents. METHODS The study has been carried out in a population of 372 Obligatory Secondary Education (OSE) students from the Institute of Secondary Education of Gandía (Valencia). RESULTS 37.8% of the adolescents have improved the level of their diet quality. Those consuming a high quality diet have increased from 30.0% to 58.6%. Also significant is the number of students that have taken up having breakfast and those having discontinued taking industrial bakery with this meal. The decrease in the number of adolescents going to fast food places and of those that have discontinued eating candies regularly is statistically significant. The data from the KIDMED index show that 47.4% (p < 0.001) of de the students have improved the quality of their diet and in none of them it has worsened. DISCUSSION Before starting the programme, 30% of the students followed a high quality diet comparable to the traditional Mediterranean Diet, and after the education programme, this percentage increased to 58.6%. Forty-seven point four percent of overweighed or obese students receiving the Nutritional Education and Intervention have improved their diet quality and the percentage of those following a high quality diet varied from 28.9% to 71.0%.

Abstract
A choledochal cyst is a cystic dilation of the intrahepatic or extrahepatic biliary tract. According to the most accepted theory, it is caused by an anomalous pancreatobiliary junction. The most important complications are cholangiocarcinoma, lithiasis, and pancreatitis. Current therapy is surgical resection. Only 20% to 30% of cases are diagnosed in adult life. Two cases of choledochal cysts are reported in female adult patients, one of them in late pregnancy and the other in puerperium. Diagnosis of choledochal cyst in pregnancy and puerperium is an uncommon event, entailing particular considerations regarding symptoms and treatment.

Abstract
A series of Fe-Ce mixed oxides (95 atom % Fe-5 atom % Ce) has been prepared by different methods: coprecipitation, impregnation, and physical mixture of Ce and Fe oxides. These solids have been tested in the Fischer-Tropsch synthesis. The characterization of the catalytic precursors was carried out by X-ray diffraction (XRD), Raman, Mössbauer, and X-ray photoelectron (XPS) spectroscopic techniques. When the preparation method ensures a microscopic contact between Fe and Ce cations in the solid, several types of Fe-Ce interactions are present in the calcined solids. The interactions take the shape of Fe-O-Ce bridges that can exist either in the hematite-like solid solution or in the interphase between the Fe oxide covered by microcrystals of Ce oxide. In the case of the hematite-like solid solution, Ce(IV) cations are dissolved in the alpha-Fe2O3 network. The promotion by Ce of the catalytic properties observed in the final catalysts can be directly related with the detection of these Fe-O-Ce bridges in the calcined solids. The Ce promotion results in a larger yield to hydrocarbons, a higher production of olefins, and a higher selectivity to medium and large chain hydrocarbons (larger than six carbon atoms). It is proposed that the Ce promotion is due to the presence of Fe0-Ce(III) ensembles in the final catalysts arising from the initial Fe-O-Ce bridges developed in the parent calcined samples.

Abstract
As suggested previously, a down-regulation of some cellular adhesion molecules (CAMs) on CD34(+) hematopoietic progenitor cells (HPC) may contribute to their egress from bone marrow (BM) to peripheral blood (PB) by decreasing their adhesion to BM stromal cells. Besides counting the percentage of CAM-positive cells, we decided to define clearly the antigen density (AgD) of the CAM on mobilized- and steady-state CD34(+) HPC using QIFIKIT calibration beads. Five sources of cells were compared: PB and BM from normal donors (nPB, nBM) cord blood (CB), mobilized PB obtained from leukapheresis products (LKP), and mobilized BM (mBM) samples. In our study the CAM-AgD was the lowest on CD34(+) cells in LKP which, on the contrary, contained the highest percentage of CD117(+), CD54(+), CD58(+) cell subsets. As for CB, a greater proportion of CD44(+) and CD62L(+) cells was observed in LKP than in other products. The LKP-CD34(+) cell population contained a greater percentage of CD11a(+) cells when compared to mBM, but the lowest percentage of CD49d(+) and CD49e(+) cells when compared to all products. The proportion of the CD34(+)CD38(-) immature subset expressing CD11a, CD44, CD54, or CD62L was greater in LKP than in mBM; the CD62L-AgD was higher in LKP than in mBM. This quantitative analysis clearly showed a downregulation of all CAM on LKP-CD34(+). The CD44, CD62L, CD11a, and CD54 AgD decrease appears to be specifically involved in the egress of the CD34(+) subsets into PB. The control of antigen density of these adhesion molecules is likely to be clinically important for effective mobilization of HPC as well as for rapid engraftment following HPC transplant.

Abstract
A clinical strain of Escherichia coli (Ec GCE) displayed resistance to cefoxitin, cefotetan, cefotaxime, and ceftazidime. Susceptibility was not restored by the addition of clavulanic acid. Two beta-lactamases with apparent pIs of 5.4 and 6.4 were identified; the beta-lactamase with a pI of 6.4 was transferred by conjugation and associated with a 40-kb plasmid. Analysis of the nucleotide sequence showed a new ampC beta-lactamase gene that is closely related to those encoding the FOX-3, FOX-2, and FOX-1 beta-lactamases but whose product has four novel amino acid mutations, at positions 11 (M-->T), 43 (A-->E), 233 (V-->A), and 280 (Y-->H). This first cephamycinase from Spain was named FOX-4.

Abstract
PURPOSE/OBJECTIVES To compare Florida Hispanic and non-Hispanic Caucasian women in their health beliefs about breast cancer and health locus of control (LOC). DESIGN Exploratory, comparative. SETTING A variety of healthcare settings in an urban area in Florida. SAMPLE Hispanic (n = 113) and non-Hispanic (n = 197) Caucasian women who could read and understand either English or Spanish. METHODS The Health Screening Questionnaire, which assesses health beliefs and health LOC, was administered in either Spanish or English, and the results were analyzed. MAIN RESEARCH VARIABLES Attitudes about health in general, perceptions about susceptibility to cancer, beliefs about benefits of early diagnosis, and perceptions about the seriousness of cancer; LOC. FINDINGS Florida Hispanic women are better educated than the Mexican American Hispanic women described in the literature. Hispanic and non-Hispanic women were significantly different in their health beliefs and LOC. With age and education controlled statistically, these differences remained. Hispanic women who preferred to speak/read English were more like the non-Hispanic women in their responses than were the women who preferred Spanish. CONCLUSIONS Cultural differences exist between Hispanic and non-Hispanic women; however, differences also exist between groups of Hispanic women in Florida versus Hispanics in the southwestern United States. IMPLICATIONS FOR NURSING PRACTICE Outreach programs for cancer screening should be culturally relevant and may need to be different for subgroups of Hispanics in the United States.

Abstract
BACKGROUND In 1992, a consensus conference defined the terms systemic inflammatory response syndrome (SIRS), sepsis, severe sepsis and septic shock. Since then, numerous reports have validated the prognostic usefulness of these operative definitions. AIM To evaluate if sepsis severity criteria, as defined by the Consensus Conference, can be applied to noninfectious SIRS. PATIENTS AND METHODS Five hundred eighteen patients admitted to 5 intensive care units (ICU) from 4 hospitals were prospectively evaluated during a 3 months period. Patients that met at least one severity criteria were included. SIRS etiology, organ dysfunction and evolution were recorded in each patient. RESULTS One hundred two patients were included: 79 with sepsis (group I) and 23 with noninfectious SIRS (group II). ICU and hospital mortality were comparable (43 and 48% in sepsis compared to 43 and 51% in non infectious SIRS). The most common sources of sepsis were pneumonia and peritonitis. Group II patients had a wide variety of diseases. ICU stay, APACHE score and number of organs with dysfunction were not different among groups. Only the incidence of renal dysfunction was higher in the septic group. CONCLUSIONS The Consensus sepsis severity criteria can be applied to noninfectious SIRS, defining a population subset with similar high mortality and organ dysfunction incidence, although with greatly heterogeneous etiologies.

Abstract
This retrospective study was undertaken to evaluate cure rates, toxicity and late effects of early intensive therapy followed by autologous stem cell transplantation (ASCT) in patients with advanced Hodgkin's disease (HD). One hundred and fifty-eight cases of ASCT registered in the French database (SFGM) were retrospectively analyzed. Disease status at the time of ASCT was first partial response (PR) in 85, first complete remission (CR1) in 45 or primary refractory in 28 cases. The median time interval between diagnosis and ASCT was 7 months (range 4-13). At the time of analysis in December 1995, 121/158 patients (76.6%) were alive, including 111 (70.2%) in continuous CR with a median follow-up for surviving patients of 46 months (range 8-123). Peri-ASCT toxic death rate was 3%, and the actuarial risk of new malignancies was 4.9% at 5 years. The cumulative probability of 5-year overall survival (OS) was 75.2% for the entire group of patients, 80.6% for the chemosensitive ones, and 33.9% for the primary refractory (chemosensitive vs refractory, P < 0.0001). The cumulative probability of 5-year event-free survival (EFS) was 66.1% for the entire group of patients, 73.7% for the chemosensitive ones, and 26.1% for the primary refractory (chemosensitive vs refractory, P < 0.0001). The only significant prognostic factor for both OS and EFS was disease status at the time of ASCT. Early ASCT in advanced HD is feasible, with a low risk of toxicity and without a higher rate of late effects compared with conventional treatment. Results achieved in chemosensitive patients at the time of transplantation lay the basis of future prospective randomized trials comparing ACST as front-line treatment to conventional treatment in high-risk cases.

Abstract
Dialysable Leucocyte Extract (DLE) is a low molecular weight dialysable material of disrupted peripheral human leucocytes with widespread effects on the immune system. We described the in vitro anti-HIV activity of DLE as well as its three chromatographic fractions (Fa, Fb and Fc). To determine the levels of inhibition on HIV replication by DLE we infected MT-4 cell cultures, using the Bru viral isolate at 0.05, 0.1, 0.5 and 1 m.o.i. Previously, MT-4 cells cultures were treated with DLE or fractions at non-toxic concentrations. Reverse transcriptase (RT) activity and p24 antigen were evaluated in culture supernatants at seven days postinfection. No effect was observed when MT-4 cells were incubated with DLE for 3 h. Whereas inhibition of HIV production was observed when MT-4 cells were pre-treated for a longer period of time. DLE inhibited p24 production and RT activity more than 50% at 0.1 m.o.i. More than 80% of inhibition was observed for all doses of DLE tested at 0.05 m.o.i. Higher viral doses (m.o.i. 0.5 and 1) were used to assess the antiviral activity of DLE fractions. Fraction Fb inhibits viral production more than 80%. Otherwise, fractions Fa and Fc did not show inhibitory effect for any viral dose used. These results indicate that DLE is able to modulate cell susceptibility to viral infection in vitro.

Abstract
The aim of this study was to determine anti HTLV-I antibody titers in seropositive symptomatic and asymptomatic infected subjects. One hundred seven infected subjects (47 with spastic paraparesis and 60 asymptomatic) were studied. HTLV-I antibodies were determined using indirect immunofluorescence in cells infected with the retrovirus. The mean titer was 1/234 in asymptomatic subjects and 1/2138 in symptomatic patients (p < 0.001). These results suggest an association between HTLV-I antibody titers and clinical stage of infected subjects.

M-CSF (monocyte colony stimulating factor) and M-CSF receptor expression by breast tumour cells: M-CSF mediated recruitment of tumour infiltrating monocytes? J Cell Biochem 1992; 50:350-6.

Abstract
Infiltrating immune cells in 30 primary human epithelial breast tumours were studied using specific anti-CD3 (T cells), anti-CD68 (macrophages), anti-CD57 (NK cells), and an anti-pan-B cell antibody (L26). The majority of tumour infiltrating inflammatory cells are T cells (40-50%) and monocytes/macrophages (15-35%). The macrophage specific chemo-attractant and growth factor CSF-1 is detected by immunohistochemical techniques (IHC) at the level of invasive breast cancer cells in 46/50 tumours but not at the level of in-situ (pre-invasive) cancer. A mosaic staining pattern was usually observed, with a very high expression in areas of obvious stromal invasion (90% cells positive) and absent or trace staining in intraductal carcinoma. Macrophages and plasma cells are equally intensely positive. In-situ hybridisation experiments confirm the production of CSF-1 (mRNA) by tumour cells and show the same pattern of expression. Expression of the CSF-1 receptor protein (fms) was also observed by IHC in 41/48 invasive tumours, albeit at weaker intensities than in tumour infiltrating monocytes/macrophages. A concomitant expression of both CSF-1 and fms in in-situ carcinoma was never seen (n = 14). It is therefore proposed that the associated expression of CSF-1 and its receptor may be linked to the invasive potential of breast cancer, the monocytic infiltrate being an indication of the quantitative importance of CSF-1 production by the tumour.

Abstract
A 49 year old "mapuche" male patient was operated on and tuberculosis of the gallbladder was found. Later on, he developed evidence of meningeal and pulmonary involvement and elevated pancreatic enzyme levels. In spite of appropriate anti-tuberculosis therapy, the patient died. Autopsy revealed multiorgan involvement with pancreatic tuberculosis and areas of steatonecrosis. Immune deficiency related to the previous cholecystectomy may have facilitated the severe dissemination of the disease observed in this patient.

Abstract
140 surgical patients were studied at the Navy Medical Center in Mexico City. All of them had a cholecystectomy performed. In addition, 29 patients were treated for hiatal hernia with troncular vagotomy, pyloroplasty and hiatal repair. 7 of them had a prophylactic appendectomy. Group A was treated with gastric intubation and subhepatic drainage. Group B received neither. Postoperative morbidity and hospitalization time less in Group B. It is suggested by the authors not to be use nasogastric intubation nor subhepatic drainage after elective cholecystectomy, although there are special circumstances where one or both procedures are indicated.

Abstract
1. Esophageal achalasia is a rare disease of unknown origin that occurs with the same frequency in both sexes. 2. During the preoperative workup as well as the postoperative time the following studies should be performed: upper GI series, esophageal manometry and endoscopy with biopsy. 3. In most instances conservative treatment with dilations only provides temporal relief of the symptoms and moreover, is not exempt from complications; it should be employed only in incipient achalasia, in patients who refuse to be operated upon and in those whose general conditions make surgery inadvisable. 4. Surgery can provide a permanent cure for the symptomatology in the majority of the patients, with a very low mortality and morbidity; an operation should be performed early in those who retain more than 10 mls. in the esophagus with persistence of the symptomatology as well as in those patients in whom cancer is suspected. 5. A modified Heller type operation, with abdominal approach with gastrostomy, diaphragmatic hernioplasty and an anti-reflux procedure and when necessary a piloroplasty is the treatment of choice for esophageal achalasia yielding good results in 88.8% of the cases. It should be noted that the degree of postoperative gastroesophageal regurgitation is directly related to the extent to which the gastric incisons is extended below the esophageal-gastric junction.
