Interpreting the full blood count

The full blood count (FBC) is one of the most commonly requested blood tests in medical practice and can provide a wealth of useful information about a patient’s general state of health, as well as highlighting abnormalities which indicate systemic or sinister pathologies. This article seeks to explore the different parameters of the FBC, and how these relate to some more common clinical presentations, as well as their relation to morphological findings seen on the blood film. As with most investigations, differential diagnoses suggested by any individual laboratory tests are wide and are most valuable when combined with history and examination.

Liquid-State Volumetric Properties of a Set of Alcohols with Up to Five Carbon Atoms

This work provides density data (~1300 values) of 14 alcohols with up to five carbon atoms at p ∈ [0.1–40] MPa and T ∈ [278–358] K. The information obtained is modeled with a convenient reformulation of the Tait equation from which the volumetric coefficients, α and β, are derived both analytically and numerically. The general EoS containing α and β is also used for checking the consistency of the hypothesis on the invariability of the cited thermophysic parameters. The results obtained can be considered reliable because of the low estimated errors between the experimental data and those of the literature, which are below 0.4% for volume, while for the volumetric coefficients there is always a reference diverging 10%, or less, from the proposed model estimations. By including the averages of α and β into the general state of equation the errors increase, being <15%, compared to those based on the Tait equation. Hence, the assumption on the stability of the volumetric coefficients in this working interval is sufficient to make rough estimations of the molar volume of the selected alcohols.

Hypoglycemic effect of alloxan and thymulin both diluted in wistars rats with degeneration of beta cells islets of Langerhans

Diabetic animals induced by alloxan show severe hyperglycemia and intense catabolism characterized by the absence of insulin. Therefore, the objective of this study is to assess whether the alloxan 6CH, is able to reverse or mitigate the changes promoted by diabetes mellitus, as well as assess the effects of thymulin. In biological tests male Wistar rats were used induced to experimental diabetes by the administration of alloxan (iv 42 mg / kg). The sample comprised four groups (n = 4): G1 – control without the induction of diabetes, G2 - diabetic without treatment, G3 - diabetic treated with thymulin 12CH and G4 - treated with alloxan 6CH. The data were statistically analyzed by ANOVA followed by Tukey-Kramer test (p < 0.05). After treatment for 40 days slight decrease of glucose in animals treated with alloxan (502 ± 28) mg/dl and thymulin (500 ± 10) mg/dl was observed compared with untreated animals (563 ± 23)mg/dl. Remained unchanged feed intake and water, however, significant decrease of body weight in diabetic group (96 ± 21)g was observed compared to animals treated with alloxan (27 ± 23)g and thymulin (20 ± 16)g, fact not observed when the last two groups are compared with the control (5.1 ± 3.9)g. Significant reduction in the percentage of lymphocytes in diabetic animals (44.8 ± 2.4)% and increase in the group treated with thymulin (12CH) (83.3 ± 4.5)% was checked, when compared to the others. Animals treated with alloxan and thymulin showed clinical improvement. Based on these findings it is concluded that alloxan and thymulin improve the general state of the animal, and suggest inhibition of strong catabolism observed in diabetic animals without treatment.

DMF as CO Surrogate in Carbonylation Reactions: Principles and Application to the Synthesis of Heterocycles

Transition metal-catalyzed carbonylation reactions have emerged as one of the most relevant synthetic approaches for the preparation of carbonyl-containing molecules. The most commonly used protocol for the insertion of a carbonyl moiety is the use of carbon monoxide (CO) but, due to its toxic and explosive nature, this process is not suitable at an industrial scale. More recently, the chemistry of CO surrogates has received large attention as a way to use less expensive and more environmentally friendly methods. Among the various CO surrogates, N,N-dimethylformamide (DMF) has been paid greater attention due to its low cost and easy availability. This mini-review gives appealing insights into the application of DMF as a CO surrogate in metal-catalyzed carbonylations; in particular, in the first part we will give a general state of the art of these reactions for the preparation of carbonyl-containing molecules; then, we will take into account all the various synthetic approaches for the metal-catalyzed carbonylative synthesis of heterocycles using DMF as a CO surrogate. Each protocol has been discussed critically in order to screen the best synthetic method and to offer perspective on trends and future directions in this field.

“People for a Nation” (PFN) Model: How Can We Manage the Causes of the Discontent of Romanians Who Decide to Emigrate

We live in a world that is constantly changing and that requires from the individuals in the society a flexibility and a very high degree of adaptation. Every change, whether economic, political, social or otherwise, has a major impact on the lives of all people and often not a positive impact. Because many individuals are inflexible and do not embrace change with enthusiasm, courage, and looking to the future, this makes them adopt a position of rejection of the country, of the systems that make up that country, of reluctance toward politics, and a general state of dissatisfaction. All this, combined, increases the desire of individuals to leave their country of origin to take refuge in a country where they have greater security and where they can embrace or are helped by the state to embrace change much faster and more effectively, so that does not suffer. The tendency of people to go to an area that offers them greater opportunities is not something new for the study of the migration phenomenon, on the contrary, it is something that has been studied and understood. What is interesting is that we can develop a model for determining a nation's desire to migrate based on the inconveniences or shortcomings it encounters in everyday life. The research we propose aims to identify the proportions that make up the population's desire to emigrate, by areas and systems and which, put together, can develop a deterministic model that we have called PFN (People for a Nation). This model allowed us not only to determine the level of desire to migrate to another country, but also gave us the opportunity to characterize a country according to those elements that bother individuals more or less.

DESARROLLO DE MODELO MURINO DE COLONIZACIÓN DE Lactobacillus plantarum LP5 DE ORIGEN PORCINO

The objective of this work was to generate an experimental model of colonization by L. plantarum LP5 in mice (Mus musculus) aimed at improving the general state of the animal and preventing the possible presence of zoonotic pathogens. The mice used were females of the Balb/cCmedc strain, 6 weeks old. Animals were organized into 2 groups of 3 individuals: treated (GT) and control (GC). GT was administered twice weekly by gavage with 100 µl of rifampicin resistant porcine L. plantarum LP5 at a concentration of 1010 CFU. Mice were fed water and food ad libitum throughout the experiment. Colonization in both groups was evaluated by the presence of clinical signs and by a microbiological analysis of the feces. Sampling was performed at weekly intervals to quantify the populations of the supplied L. plantarum LP5, Lactobacillus spp., Escherichia coli, total coliforms, Campylobacter and yeast. The results of the sampling in the GT in the week showed a recovery of L. plantarum LP5 above 5 logUFC/g, in the second it was 7 logUFC/g and in the third it was 5 logUFC/g. The CG, meanwhile, maintained the null count throughout the experiment. The results showed that there was no imbalance between the microbial components. Therefore, it is feasible to affirm that the inoculum did not alter the balance of the intestinal ecosystem. Particularly, it did not exert an inhibitory effect on the members of the previously established microbiota.

Health-Related Quality of Life according to Renal Function: Results from a Nationwide Health Interview and Examination Survey

<b><i>Background:</i></b> Most studies on health-related quality of life (HRQoL) in chronic kidney disease (CKD) focus on patients with end-stage kidney disease although they represent a small proportion of patients with CKD. We aimed to analyze HRQoL according to glomerular filtration rate (GFR) categories in a population-based sample of adults living in Germany. <b><i>Methods:</i></b> Data from the German health interview and examination survey conducted from 2008 to 2011 were used. Participants with valid interview and examination data aged 40–79 years were included (<i>n</i> = 5,159). Serum creatinine levels were used to calculate estimated GFR via the Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) equation. We classified kidney function in GFR categories according to the Kidney Disease Improving Global Outcomes Initiative (KDIGO) guidelines on CKD: G1 (high): ≥90 mL/min/1.73 m², G2 (normal): 60–89 mL/min/1.73 m², G3a (mildly decreased): 45–59 mL/min/1.73 m², G3b (moderately decreased): 30–44 mL/min/1.73 m², G4/5 (severely decreased/end-stage kidney disease): &#x3c;30 mL/min/1.73 m². HRQoL was evaluated with the Short Form Health Survey (SF-36). Different multivariate linear and logistic regression models were used to analyze the association of HRQoL with GFR categories. <b><i>Results:</i></b> Overall, 5.9% had a GFR &#x3c;60 mL/min/1.73 m² (corresponding to categories G3a, G3b, and G4/5). Compared to category G2 linear regression showed a decline in physical HRQoL in categories G3a (−2.34, <i>p</i> = 0.004), G3b (−5.37, <i>p</i> = 0.009), and G4/5 (−4.82, <i>p</i> = 0.117). No decline in mental HRQoL was detected with increasing GFR categories. Categories G3a to G4/5 were significantly associated with a low perceived general state of health (G3a: odds ratio [OR] = 2.03, <i>p</i> = 0.001; G3b: OR = 3.01, <i>p</i> = 0.009; G4/5: OR = 8.70, <i>p</i> = 0.016) when compared to category G2. <b><i>Conclusion:</i></b> In a representative sample of adults living in Germany, both physical HRQoL and the perceived general state of health are already significantly reduced in category G3a.
