<p>After two years of work, we have explored most of water systems of the western region of Tiaret areas; represented mainly by the Oued Mina and Oued Louhou. The study started with a sampling, executed successively during Autumn and Spring, with the aim to identify the diatomic flora on the first part; and to analyze the ecology of these diatoms on the other part, regarding the Environmental factors through canonical correspondence analysis in order to estimate the organic pollution index. Our results highlighted 104 inventoried species, distributed on 20 different families, with 13 new taxa as a new record in Algeria: Brachysira microcephala, Eunotia cataractarum, Hippodonta capitata, Luticola kotschyi, Luticola nivalis Neidium binodeforme,<br />Neidium ampliatum, Neidium dubium, Nitzschia bita, Nitzschia sinuata var. Tabellaria. Pinnularia obscura, Stauroneis gracilis and Surirella crumena. Otherwise, the calculation of the Organic Pollution Index OPI along the describing stations shows a degraded condition of the quality of water in Oued Mina, due to the discharge of domestic and industrial waste water from agglomerations. Four functional groups of the diatoms were revealed. A functional group A is presented by 21 species. The high<br />trophy preference is a most important ecological property of the functional group A. Species which constitute this functional group are mainly eutraphentic. A functional group B is presented by 10 species. Species which constitute this functional group are mainly acidophilous. A functional group C is presented by 20 species. The preference of the low nitrogen level is a most important ecological property of the functional group C. A functional group D is presented by 8 species. Species which constitute this functional group are mainly facultatively nitrogen-heterotrophic taxa needing periodically elevated concentration of<br />organically bound nitrogen.</p>

The article analyzes the physical and psychological components of the quality of life (QOL) in patients with diabetic polyneuropathy (DP) on the background of type I and II diabetes mellitus (DM) with comorbidity. Has been demonstrated the prevalence of more frequent multimorbidity in this nosology and its effect on patients’ QOL. QOL is recognized as an integral part of a comprehensive analysis of new methods of diagnosis, treatment, prevention, quality of treatment and medical assistance [2]. With the highest frequency in DM detect sensory or sensorimotor forms of distal symmetrical DP. However, there are motor symptoms in DM, including cranial neuropathy and Bruns-Garland syndrome (diabetic amyotrophy) [3], which interfere with the satisfactory functioning of patients. The purpose of our work was to assess the extent of physical and mental functioning of people with DP on the background of multimorbidity. Materials and methods. We examined 92 patients with DP on the background of type I and II DM, aged from 19 to 69 years, which were divided into 2 groups: from DP on the background of type 1 DM (group I) and type II (group II). We distinguished such subgroups: DP on the background of type I DM and concomitant cardiovascular pathology (CVP) (group A), DP on the background of type II DM and concomitant CVP (group B), DP on the background of type I DM and gastroenterological pathology (GEP) (group C), DP on the background of type II DM and GEP (group D), DP on the background of type I DM and pathology of the thyroid gland (thyroid) (group E), DP on the background of type II DM and thyroid pathology (group F). Patients underwent clinical and neurological examination, laboratory tests and ultrasound examination of the abdominal cavity and thyroid gland, electromyography (EMG). Static calculation was done in MS Excel 2003. Results and discussion. In groups A and B with the highest frequency among CVP was arterial hypertension - 91% vs 97% and coronary heart disease - 27% vs 41%. In group C - chronic hepatitis (40%), chronic cholecystitis (40%), chronic pancreatitis (40%), chronic gastroduodenitis (40%). In people of group D, gallstone disease was diagnosed more often than in other pathologies (43%). The leading place in group E was occupied by autoimmune thyroiditis (29%), idiopathic hypothyroidism (29%), thyrotoxicosis (29%), in group F - nodular goiter (57%). The longest duration of DM was observed in group A - 24.54 ± 2.46 years, the smallest in group D - 7.14 ± 1.01 years. Diabetic foot syndrome was diagnosed in patients of groups A and B in 14%, group C - in 2%. In patients of group I, the indicators of QOL were higher than in group II. The highest indicators were of groups I and II in the domains social (SF) and physical functioning (PF) - 66.75 ± 2.41; 65.5 ± 3.23 and 63.39 ± 3.54; 61.42 ± 3.88. In group A, the level of QOL was slightly higher than in group B, in particular in the domains of mental health (MH) - 53.09 ± 3.12, bodily pain (BP) - 50.90 ± 4.05. In addition, the manifestations of DP in such group of individuals (group A) were manifested by the absence or mild pain, which causes in people of this group higher rate of QOL. QOL in patients of group C was higher than in group D, in particular, the indicators of physical functioning (PF) - 68.75 ± 5.88, social functioning (SF) - 65.62 ± 5.35, role emotional (RE) - 58.33 ± 18.75, mental health (MH) - 54 ± 5.36. In group D, the data were high in the domains of social functioning (SF) 60.71 ± 16.0 and physical functioning (PF) 57.14 ± 8.37. In the examined patients of group F the level of QOL was higher than in group E, it was, in the domains of physical functioning (PF) - 76.42 ± 7.99, bodily pain (BP) - 61.28 ± 11.18, general health (GH) - 60.85 ± 7.33. Physical health (PH) was low in all groups, but slightly higher in group F (47.90 ± 3.45). The mental health (MH) was low in all groups of patients, slightly higher in group C (47.89 ± 3.59). Conclusions. The level of QOL in persons with DP on the background of type I and II DM with multimorbidity was generally not high. Patients in group D showed the lowest levels of QOL, they also had a level of glycated hemoglobin much higher than in other groups. In group F, the data of QOL were higher, because people with DP on the background of type I DM (group E) had a higher frequency of concomitant thyroid damage, the manifestations of which significantly complicate the course of the underlying disease and reduce levels of functioning. Often manifestations of diabetic foot occur in the onset of DP, when the fibers responsible for sensitivity were damaged, which causes the appearance of the neuropathic component of pain, so in persons of group B the lowest among all groups was the level of QOL in the domain of pain intensity. In addition, it was convenient to monitor the results of treatment by conducting a QOL survey several times a year. Careful analysis of QOL in all areas of functioning in patients with DP allowed detecting early mental disorders and timely start treatment, including psychotherapy sessions.

The purpose of this study was to evaluate selected quality traits of chicken eggs in relation to their weight (weight categories). The experimental material comprised eggs from 250 laying hens (♂ New Hampshire x ♀ Barred Rock). The birds were kept in a poultry house on litter in identical hygienic conditions and fed ad libitum the same compound feed, of appropriate nutritional value, during the rearing and egg production period. At 36 weeks of age 160 eggs were taken at random from the hens and divided into four weight categories: below 57.0 g (group A); 57.1 to 60.0 g (group B); 60.1 to 63.0 g (group C) and above 63.0 g (group D). The quality of the albumen, yolk and shell was evaluated and the concentration and hydrolytic activity of lysozyme was determined in individual albumen fractions. Eggs from group D had the highest share of albumen (60.92%) and the smallest share of shell (10.56%). Furthermore, the albumen of these eggs had the greatest weight (40.19 g) and height (6.61 mm), and the yolks had the highest weight (18.13 g) and darkest colour (13.65 pts). The eggs assigned to group B had greater shell thickness (352.46 μm) and strength (38.2 N). Detailed analysis of lysozyme activity showed that the albumen of the group A eggs had the highest lysozyme concentration and hydrolytic activity in both albumen fractions analysed (0.61%; 131,105 U/ml – thin albumen and 0.38%;80,705 U/ml – thick albumen). The study showed that the heaviest eggs had the most favourable traits for the consumer. They were distinguished by good albumen quality (the greatest weight and height) and yolk quality (the greatest weight and darkest colour). Moreover, their shells were fairly thick (352.37 μm) and the least susceptible to deformation (70.90 μm). On the other hand, the albumen of the eggs in the lowest weight category had the highest concentration and hydrolytic activity of lysozyme.

The unique position of man as a master mechanic of the animal kingdom is because of skilled movements of his hands and when this shoulder joints get obstructed, we call it as Apabahuka (Frozen shoulder), we do not find satisfactory management in modern medical science. Various effective treatment modalities have been mentioned which reverse the pathogenesis, Shodhana is advised initially followed by Shamana therapies. In the present study 30 patients were selected incidentally and placed randomly into two groups A and B, with 15 subjects in each group. Group A received Amapachana with Panchakola Churna, Jambeera Pinda Sweda and Nasya Karma. Group B received Amapachana with Panchakola Churna, Jambeera pinda Sweda and Nasaapana. In both the groups two months follow up was done. Both groups showed significant improvement in the signs and symptoms of Apabahuka as well as the activities of daily livings, thereby improving the quality of life of the patients. Nasya Karma and Nasaapana provided highly significant results in all the symptoms of Apabahuka. In the present study as per the clinical data, Nasaapana is found to be more effective than Nasya Karma.

The study was to determine the presence of Classical Swine Fever virus (CSFv), in the meat of vaccinated pigs with the PAV-250 strain and then challenged using the same strain. Five treatment groups were established (each with four pigs). Group A: Pigs thatwere fed with processed hams from negative animals; Group B: Pigs that were fed with processed hams from commercial pigs inoculated with the ALD (reference strain) (titre of 104.0/ml); Group C: Pigs fed with processed hams from pigs infected with the virulent ALD strain (titre of 102.5/ml); Group D: Pigs fed with processed hams from pigs vaccinated with the PAV-250 strain and challenged with the ALD strain (titre of 101.1/ml); and Group E: Pigs fed with processed hams from pigs vaccinated with two doses of the PAV-250 strain and challenged with the ALD strain (negative). Blood samples were taken at d 1, 5, 10, 15 and 20 for biometric analysis. Groups B, C and D manifested clinical signs of CSFv: 40 °C temperature, anorexia, paralysis, vomiting, diarrhea, tremor, hirsute hair and cyanosis. Pigs were slaughtered and necropsies performed to identify lesions in tissues. Results of direct immunofluorescence testing of tissues were positive and the virus was recovered. Under these study conditions, it was found that CSFv resisted the cooking method at 68 °C for 40 min in hams from unvaccinated pigs, and that the virus was able to transmit the disease to healthy unvaccinated pigs, whereas the hams from the vaccinated animals did not transmit the virus.

Introduction Joint involvement represents the major determinant in quality of life (QoL)in Systemic Lupus Erhytematosus (SLE) patients. However, QoLhas been generally evaluated by non-specific questionnaires. We evaluated the relationship between SLE musculoskeletal manifestations and QoL, assessed by LupusQoL. Methods Patients with joint involvement (group A) were compared with those without this feature (group B). Disease activity was assessed by SLEDAI-2k in the whole population, while DAS28 and swollen to tender ratio were applied to assess joint activity. LupusQoL was administered to all the patients. Results Group A included 110 patients [M/F 8/102; median age 49 years (IQR 13), median disease duration 156 months (IQR 216)], group B 58 [M/F 11/47; median age 40 years (IQR 15), median disease duration 84 months (IQR 108)].We found significanlty lower values in all the LupusQoL domains except for one (burden to others) in group A in comparison with group B. A significant correlation between DAS28 values and all the LupusQoL domains in group A was found; only three domains correlated with SLEDAI-2k. Conclusions SLE-related joint involvement significantly influences disease-specific QoL. DAS28 better correlated with LupusQoL domains in comparison with SLEDAI-2k, confirming the need for specific musculoskeletal activity indices.

<b><i>Introduction:</i></b> The aim of this was to describe the predictors of mortality related to COVID-19 infection and to evaluate the association between overweight, obesity, and clinical outcomes of COVID-19. <b><i>Methods:</i></b> We included the patients &#x3e;18 years of age, with at least one positive SARS-CoV-2 reverse transcriptase-polymerase chain reaction. Patients were grouped according to body mass index values as normal weight &#x3c;25 kg/m<sup>2</sup> (Group A), overweight from 25 to &#x3c;30 kg/m<sup>2</sup> (Group B), Class I obesity 30 to &#x3c;35 kg/m<sup>2</sup> (Group C), and ≥35 kg/m<sup>2</sup> (Group D). Mortality, clinical outcomes, laboratory parameters, and comorbidities were compared among 4 groups. <b><i>Results:</i></b> There was no significant difference among study groups in terms of mortality. Noninvasive mechanical ventilation requirement was higher in group B and D than group A, while it was higher in Group D than Group C (Group B vs. Group A [<i>p</i> = 0.017], Group D vs. Group A [<i>p</i> = 0.001], and Group D vs. Group C [<i>p</i> = 0.016]). Lung involvement was less common in Group A, and presence of hypoxia was more common in Group D (Group B vs. Group A [<i>p</i> = 0.025], Group D vs. Group A [<i>p</i> &#x3c; 0.001], Group D vs. Group B [<i>p</i> = 0.006], and Group D vs. Group C [<i>p</i> = 0.014]). The hospitalization rate was lower in Group A than in the other groups; in addition, patients in Group D have the highest rate of hospitalization (Group B vs. Group A [<i>p</i> &#x3c; 0.001], Group C vs. Group A [<i>p</i> &#x3c; 0.001], Group D vs. Group A [<i>p</i> &#x3c; 0.001], Group D vs. Group B [<i>p</i> &#x3c; 0.001], and Group D vs. Group C [<i>p</i> = 0.010]). <b><i>Conclusion:</i></b> COVID-19 patients with overweight and obesity presented with more severe clinical findings. Health-care providers should take into account that people living with overweight and obesity are at higher risk for COVID-19 and its complications.

Background:Cardiovascular disease (CVD) is detected in up to 50% of systemic lupus erythematosus (SLE) patients1and major cause of death2. Even clinically silent SLE patients can develop left ventricular (LV) diastolic dysfunction3. Proper echocardiographic follow up of SLE patients is required.Objectives:To clarify how the prevalence of LV abnormalities changes over follow-up period and identify the associated clinical factors, useful in suspecting LV abnormalities.Methods:29 SLE patients (24 females and 5 men, mean age 52.8±16.3 years, mean disease duration 17.6±14.5 years) were enrolled. All of them underwent echocardiography as the baseline examination and reexamined over more than a year of follow-up period(mean 1075±480 days) from Jan 2014 to Sep 2019. Patients complicated with pulmonary artery hypertension, deep venous thrombosis or pulmonary embolism and underwent cardiac surgery during the follow-up period were excluded. Left ventricular(LV) systolic dysfunction was defined as ejection fraction (EF) < 50%. LV diastolic dysfunction was defined according to ASE/EACVI guideline4. LV dysfunction (LVD) includes one or both of LV systolic dysfunction and LV diastolic function. Monocyte to HDL ratio (MHR) was calculated by dividing monocyte count with HDL-C level.Prevalence of left ventricular abnormalities was analysed at baseline and follow-up examination. Clinical characteristics and laboratory data were compared among patient groups as follows; patients with LV dysfunction (Group A) and without LV dysfunction (Group B) at the follow-up echocardiography, patients with LV asynergy at any point of examination (Group C) and patients free of LV abnormalities during the follow-up period (Group D).Results:At the baseline examination, LV dysfunction (5/29 cases, 13.8%), LV asynergy (6/29 cases, 21.7%) were detected. Pericarditis was detected in 7 patients (24.1%, LVD in 3 patients, LV asynergy in 2 patients) and 2 of them with subacute onset had progressive LV dysfunction, while 5 patients were normal in echocardiography after remission induction therapy for SLE. At the follow-up examination, LV dysfunction (9/29 cases, 31.0%, 5 new-onset and 1 improved case), LV asynergy (6/29 cases, 21.7%, 2 new-onset and 2 improved cases) were detected. Though any significant differences were observed between Group A and Group B at the baseline, platelet count (156.0 vs 207.0, p=0.049) were significantly lower in LV dysfunction group (Group A) at the follow-up examination. Group C patients had significantly higher uric acid (p=0.004), monocyte count (p=0.009), and MHR (p=0.003) than Group D(results in table).Conclusion:LV dysfunction is progressive in most of patients and requires regular follow-up once they developed. Uric acid, monocyte count and MHR are elevated in SLE patients with LV asynergy. Since MHR elevation was reported as useful marker of endothelial dysfunction5, our future goal is to analyse involvement of monocyte activation and endothelial dysfunction in LV asynergy of SLE patients.References:[1]Doria A et al.

Abstract Background Pernicious placenta previa (PPP) can increase the risk of perioperative complications. During caesarean section in patients with adherent placenta, intraoperative blood loss, hysterectomy rate and transfusion could be reduced by interventional methods. Our study aimed to investigate the influence of maternal hemodynamics control and neonatal outcomes of prophylactic temporary abdominal aortic balloon (PTAAB) occlusion for patients with pernicious placenta previa. Methods This was a retrospective study using data from the Peking University People’s Hospital from January 2014 through January 2020. Clinical records of pregnant women undergoing cesarean section were collected. Patients were divided into two groups: treatment with PTAAB placement (group A) and no balloon placement (group B). Group A was further broken down into two groups: prophylactic placement (Group C) and balloon occlusion (group D). Results Clinical records of 33 cases from 5205 pregnant women underwent cesarean section were collected. The number of groups A, B, C, and D were 17, 16, 5 and 12.We found that a significant difference in the post-operative uterine artery embolism rates between group A and group B (0% vs.31.3%, p = 0.018). There was a significant difference in the Apgar scores at first minute between group A and group B (8.94 ± 1.43 vs 9.81 ± 0.75,p = 0.037),and the same significant difference between two groups in the pre-operative central placenta previa (29.4% vs. 0%,p = 0.044), complete placenta previa (58.8% vs 18.8%, p = 0.032),placenta implantation (76.5% vs 31.3%, p = 0.015). We could also observe the significant difference in the amount of blood cell (2.80 ± 2.68vs.10.66 ± 11.97, p = 0.038) and blood plasma transfusion (280.00 ± 268.32 vs. 1033.33 ± 1098.20, p = 0.044) between group C and group D. The significant differences in the preoperative vaginal bleeding conditions (0% vs 75%, p = 0.009), the intraoperative application rates of vasopressors (0% vs. 58.3%, p = 0.044) and the postoperative ICU (intensive care unit) admission rates (0% vs. 58.3%, p = 0.044) were also kept. Conclusions PTAAB occlusion could be useful in reducing the rate of post-operative uterine artery embolism and the amount of transfusion, and be useful in coping with patients with preoperative vaginal bleeding conditions, so as to reduce the rate of intraoperative applications of vasopressors and the postoperative ICU (intensive care unit) admission. In PPP patients with placenta implantation, central placenta previa and complete placenta previa, we advocate the utilization of prophylactic temporary abdominal aortic balloon placement.

Abstract Background How to perform minimally-invasive surgery on Tile C pelvic fractures is very difficult, and it is also a hot topic in orthopedic trauma research. We applied minimally-invasive treatment using an anterior internal fixator combined with sacroiliac screws. Objectives To compare the biomechanical properties of different fixation models in pelvic facture specimens, using an internal fixation system or a steel plate combined with sacroiliac screws. Methods Sixteen fresh adult cadaver pelvic specimens were randomly separated into four groups named A, B, C, and D. The four groups were respectively stabilized using a two-screwed, three-screwed, or four-screwed anterior internal fixator or a steel plate with sacroiliac screws. All models were tested in both standing and sitting positions. Vertical loads of 600 N were applied increasingly. Shifts of bilateral sacroiliac joints and pubis rupture were measured. Results The shifts in sacroiliac joints and pubis rupture in the standing position were all less than 3.5 mm, and the shifts in the sitting position were all less than 1 mm. In the standing position, the results of shifts in the sacroiliac joints were group C < group D < group B < group A. For comparisons between A:B and C:D, P > 0.05. For comparisons between A, B:C, and D, P < 0.05. The results of shifts in pubis ruptures were group D < group C < group B < group A. In the comparison between C:D, P > 0.05; for comparisons between A:B, A:C, A:D, B:C, and B:D, P < 0.05. In the sitting posture, the results of shifts in the sacroiliac joints were group C < group D < group B < group A, and the shifts in the pubis ruptures were group D < group C < roup B < group A. For comparison between C:D, P > 0.05. For comparisons between A:B, A:C, A:D, B:C, and B:D, P < 0.05. Conclusion Use of an anterior internal fixator combined with sacroiliac screws effectively stabilized Tile C3 pelvic fractures. The stability of specimens increased as the number of screws in the internal fixator increased.

Exposure of sheep to Borreliaburgdorferi sensulato (s.I.) complex, the causative agent of Lyme borreliosis (LB), has been reported in tick-abundant areas worldwide, while no data have been reported in Greece. The aim of the study was to identify the hematological alterations in sheep with seropositivity against Borrelia burgdorferi (s.I.). Blood samples were obtained from 318 tick infested sheep for blood analysis and serological determination of IgG and IgM antibodies against B. burgdorferi by indirect immunofluorescence antibody (IFA) assay after exclusion of endo-ectoparasites and other tick-borne infections. A total number of 162 sheep met the inclusion criteria, allocated in four groups based on the presence or absence of IgG and/or IgM; sheep found negative for IgM and IgG (Group A), positive for IgM (Group B), positive for both IgM and IgG (Group C) and positive for IgG (Group D). Anemia, thrombocytopenia and normal or decreased leukocyte count, mainly due to lymphopenia were the main hematological features observed in seropositive sheep. The presence of these features raises the suspicion of Borrelia infection in tick infested sheep. The seropositivity of 23.58% in sheep raises concerns of Borrelia circulation, especially in rural areas and potential risk of transmission to humans.
