Correlation among periodontal health status, maternal age and pre-term low birth weight
No full textPurpose: To assess correlations between periodontal status, maternal age and adverse pregnancy outcomes, such as pre-term and low birth weight in a sample of pregnant women. Methods: Study population was represented by outpatient pregnant women, gestational age > 26 weeks. Medical history questionnaires were administered to all participants who underwent clinical evaluation; clinical obstetric outcome records were collected after delivery. A questionnaire was administered regarding personal information, socio-economic status, oral hygiene habits, and oral health conditions. A clinical oral examination was performed to collect Simplified Oral Hygiene Index (OHI-S) and Community Periodontal Index (CPI). Pregnancy outcome records included: delivery week, kind and causes of delivery, any relevant complications, and birth weight. Descriptive statistics were used to depict the data from the questionnaire while the relationship between delivery week, birth weight, maternal age and periodontal status was evaluated through multivariate tests of significance. Results: 88 pregnant women were enrolled in the study. The results showed a statistically significant correlation (P<0.001) among participants older than 40 years of age, between periodontal disease and adverse pregnancy outcomes. No statistical correlation was found among pre-term and low birth weight, smoking, ethnicity and educational level of mothers. The results highlight the importance of including a routine oral and periodontal health examination in pregnant women older than 40 years of age
Penn classification in acute aortic dissection patients
No full textObjective The objective of this study was to evaluate the effectiveness of the Penn classification in predicting in-hospital mortality after surgery
in acute type A aortic dissection patients.
Methods We evaluated 58 patients (42 men and 16 women; mean age 62.17 ± 10.6 years) who underwent emergency surgery for acute type A
aortic dissection between September 2003 and June 2010 in our department. We investigated the correlation between the pre-operative malperfusion
and in-hospital outcome after surgery.
Results Twenty-eight patients (48%) were Penn class Aa (absence of branch vessel malperfusion or circulatory collapse), 11 (19%) were Penn class
Ab (branch vessel malperfusion with ischaemia), 5 (9%) were Penn class Ac (circulatory collapse with or without cardiac involvement) and 14 (24%) were
Penn class Abc (both branch vessel malperfusion and circulatory collapse). The number of patients with localized or generalized ischaemia or both, Penn
class non-Aa, was 30 (52%). In-hospital mortality was 24%. In-hospital mortality was significantly higher in Penn class Abc and Penn class non-Aa. Intensive
unit care stay, hospital ward stay and overall hospital stay was longer in Penn class non-Aa vs Penn class Aa. De Bakey type I dissection and type II diabetes
mellitus were associated with in-hospital mortality.
Conclusion Preoperative malperfusion is important for the evaluation of patients with acute aortic type A dissection. The Penn classification is
a simple and quick method to apply and predict in-hospital mortality and outcomes.
Keywords Type A dissection – Stanford classification – DeBakey classification – Penn classification

Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
No full text“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Impact of Prosthesis-Patient Mismatch after Mitral Valve Replacement
No full textBackground and aim of the study: The study aim was
to determine the impact of prosthesis-patient
mismatch (PPM) on early and late clinical outcomes,
left atrial and ventricular remodeling, late tricuspid
valve regurgitation and pulmonary hypertension
(PH) in patients after mitral valve replacement
(MVR).
Methods: A total of 46 patients (mean age 66 ± 9.3
years) with mitral valve diseases and undergoing
isolated MVR was enrolled in the study. The mitral
valve effective orifice area (EOA) was determined
using the continuity equation and indexed for the
patient’s body surface area (EOAi). PPM was defined
as EOAi ≤1.2 cm2/m2. PH was defined as a systolic
pulmonary artery pressure (sPAP) >40 mmHg. Both,
clinical and echocardiographic follow up were
performed.
Results: PPM was identified in 25% of patients, but
no significant differences were observed in baseline
and operative characteristics when comparing
patients with and without PPM. The NYHA class
was improved in most cases after surgery. Indeed,
significant decreases in mean transvalvular gradient
(from 8.6 ± 2.8 mmHg to 5 ± 1.3 mmHg, p = 0.001),
left atrial dimension (LAD) (from 31.9 ± 9.8 mm to
29.5 ± 7 mm, p = 0.011), left ventricular end-systolic
diameter (from 42.6 ± 18.1 mm to 35.5 ± 6.6 mm,
p = 0.044) and left ventricular end-diastolic diameter
(from 55.8 ± 19.2 mm to 48.7 ± 6.1 mm, p = 0.024) were
observed over time when comparing preoperative
and postoperative echocardiographic data. In
addition, at follow up (mean 6.9 ± 1.8 years) there
were significant decreases in LAD (from 31.9 ± 9.8
mm to 28 ± 11.1 mm, p = 0.001), left ventricular enddiastolic
volume (from 106.9 ± 32.9 ml to 92.3 ± 21.9
ml, p = 0.024), tricuspid regurgitation (TR) (from 87%
to 27%, p = 0.002) and PH (from 78.3% to 58.7%,
p = 0.043) in all patients. No significant differences
were observed in hemodynamic, clinical outcome
and atrial natriuretic peptide levels of patients with
and without PPM.
Conclusion: Mitral PPM does not appear to have any
negative effect on ventricular and atrial remodeling,
TR and PH during the early and late postoperative
periods
Využití sociálních médií v B2B prodeji
No full textTato diplomová práce se zabývá tím, jak mohou B2B obchodníci využívat sociální média v prodeji. Na základě systematické rešerše literatury, autor zjistil, že akademici, zkoumající danou problematiku, navrhují další výzkum, a to: v kterých konkrétních krocích se dají využít sociální média v prodeji (Salo, 2017). Autor se na základě toho rozhodl zjistit, jaké sociální sítě, různé technologie a pluginy se dají využít v B2B prodeji - tzv. social sellingu. Social selling se v této práci týká primárně procesu akvizice a okrajově péčí o stávající zákazníky. Autor si vybral kvalitativní průzkum pomocí 10 hloubkových polo-strukturovaných rozhovorů, aby odhalil jak, která sociální média to jsou, tak i motivaci prodejců, proč tato média používat/nepoužívat. Aby autor dodržel správnost vyhodnocení výsledků, data byla analyzována pomocí Tématické analýzy, která v této studii vykrystalizovala 2 hlavní strategické přístupy v social sellingu. Tyto přístupy (tzv. Push a Pull strategie) obsahují praktické příklady a konkrétní aktivity, které mohou prodejci využívat v každodenní praxi. Tyto výsledky jsou prezentovány s důrazem na praktičnost a jednoduchost implementace. Tvoří proto hlavní přínos autorovo výzkumu. V poslední části autor zmiňuje výzvy a manažerská doporučení, které mohou obchodníci využít v každodenním pracovním životě.This diploma thesis focuses on social media usage in B2B sales. Based on the systematic literature review conducted by the author, he has found out that recent researchers (Salo, 2017) suggest further research in the area of how and in which sales phase should various social networking sites, technologies and plugins used. To further fill this research gap, author decided to identify these social media and their usage among B2B salespeople in the so-called social selling process. The social selling process in this thesis applies mainly to acquiring new prospects and tangentially to taking care of existing clients (follow-up step). Author has chosen a qualitative research method via conducting 10 in-depth semi-structured interviews to reveal these instruments as well as motivation of a sales person on why to use social media in the selling process. The collected data was analyzed using Thematic analysis to ensure the right procedure and to identify main themes which crystalized into 2 main strategic approaches in social selling. These approaches (Push and Pull) include practical examples of concrete activities which sales people can use in their daily jobs and are presented with focus on practicality and ease of implementation. These also form the main contribution of author`s research. In the last part, author mentions challenges in social selling and recommended managerial implications for salesforce
TeX v jednoduchém unixovém prostředí
No full textsummary:Při ladění TeXového dokumentu potřebujeme mnohokrát opakovaně pouštět TeX, podívat se, jak dopadl výsledek v prohlížeči DVI nebo PDF souboru, mrknout na výpis TeXu na terminálu, podívat se případně do logu a celou činnost opakovat. V tomto článku je ukázáno, jak tuto práci dělá autor článku. Proces "editor-TeX-kuk" je zde podporován jednoduchými unixovými nástroji: bashovým skriptem texloop, který si autor pro tyto účely vytvořil, dále terminálem Xterm a jednoduchým editorem, který umí navázat na klávesovou zkratku spuštění příkazu v systému. Čtenář se zde může inspirovat a přizpůsobit tyto nástroje svým vlastním potřebám. V článku je popsána funkce skriptu texloop, dále je neformálně rozveden dlouholetý vývoj autorova vztahu k textovým editorům a konečně je zde uvedena konfigurace terminálu Xterm, aby vyhovoval českému prostředí jak v kódování ISO-8859-2, tak v kódování UTF-8. Pro kódování UTF-8 si v závěru článku vygenerujeme TeXový formát csplain.summary:By debugging a TeX document it is necessary many times repeatedly to run TeX, to look for the result in DVI or PDF file, to gander the TeX output on the terminal, or eventually to have a look in the log-file, and all that action to repeat. In the paper it is show, how this work is made by author. The process '‘'editor-TeX-look' is supported by simple Unix tools: bash script texloop, created by author for these purposes, Xterm terminal and a simple editor, which is able to link to the shortcut key the activation of a system command. The reader could be inspired with the solution and to adapt these tools to his/her own needs. In the paper the function of the texloop script is described, and further the longstanding evolution of the author's relation to text editors is informal elaborated and finally a configuration of Xterm terminal, suitable for the czech environment with both ISO-8859-2 and UTF-8 encoding is introduced. For UTF-8 encoding the TeX format csplain is generated at the end of the paper
