Stealing Home in Hollywood: Why the Takeover of the Los Angeles Dodgers Illustrates the Unjust Nature of Major League Baseball\u27s Antitrust Exemption
The article discusses Major League Baseball\u27s (MLB) takeover of the Los Angeles Dodgers baseball team from owner Frank McCourt following his divorce from his wife Jamie, as well as MLB\u27s alleged unjust antitrust exemption as of September 2012. The author argues that McCourt could have challenged the anti-competitive takeover practices of MLB and its commissioner Bud Selig since McCourt\u27s attempt to broker a television deal with Fox Sports did not break any of MLB\u27s rules

Epilepsy and hypertension: The possible link for sudden unexpected death in epilepsy?
Epilepsy affects about 50 million people worldwide. Sudden unexpected death in epilepsy (SUDEP) is the main cause of death in epilepsy accounting for up to 17% of all deaths in epileptic patients, and therefore remains a major public health problem. SUDEP likely arises from a combination and interaction of multiple risk factors (such as being male, drug resistance, frequent generalized tonic-clonic seizures) making risk prediction and mitigation challenging. While there is a general understanding of the physiopathology of SUDEP, mechanistic hypotheses linking risk factors with a risk of SUDEP are still lacking. Identifying cross-talk between biological systems implicated in SUDEP may facilitate the development of improved models for SUDEP risk assessment, treatment and clinical management. In this review, the aim was to explore an overlap between the pathophysiology of hypertension, cardiovascular disease and epilepsy, and discuss its implication for SUDEP. Presented herein, evidence in literature in support of a cross-talk between the renin–angiotensin system (RAS) and sympathetic nervous system, both known to be involved in the development of hypertension and cardiovascular disease, and as one of the underlying mechanisms of SUDEP. This article also provides a brief description of local RAS in brain neuroinflammation and the role of centrally acting RAS inhibitors in epileptic seizure alleviation
Influence of genetic factors on early hypertensive complications
Choroby układu krążenia są główną przyczyną zachorowalności,
zgonów i inwalidztwa w rozwiniętych
krajach świata. Najważniejszym czynnikiem ryzyka
prowadzącym do rozwoju powikłań narządowych
jest nadciśnienie tętnicze. Niniejszy artykuł jest
poświęcony głównie powikłaniom naczyniowym
(zaburzenia funkcji śródbłonka i przebudowa ściany
tętnic) oraz mikroalbuminurii. W pracy opisano aktualny
stan wiedzy o wpływie wybranych czynników
genetycznych na predyspozycję do rozwoju powikłań
nadciśnienia tętniczego. Czynniki te obejmują warianty
polimorficzne genów kandydatów, zaangażowanych
między innymi w regulację ciśnienia krwi,
hemostazę, stres oksydacyjny i proces zapalny.
Stwierdzenie predyspozycji genetycznej do rozwoju
wczesnych powikłań sercowo-naczyniowych jest niezwykle
istotnym czynnikiem ryzyka wystąpienia poważniejszych powikłań — zawału serca czy udaru
mózgu — i może zrewolucjonizować metody diagnostyki
chorób, oceny ryzyka i prognozowania oraz
wyboru terapii.
Nadciśnienie Tętnicze 2011, tom 15, nr 2, strony 125–142.Hypertension is the most prevalent risk factor for cardiovascular
disease (CVD), the leading cause of death
worldwide, especially in developed countries. Genetic
and environmental determinants play important roles
in hypertension and its complications. This publication
gives a short introduction to the pathogenesis of CVD
and summarizes the current findings of the genetic factors
involved. This review focuses on a better understanding
of the role of candidate genes polymorphisms
that play a crucial role in blood pressure regulation,
hemostatic processes, oxidative stress and inflammatory
responses leading to endothelial damage, and as a result,
to vascular remodeling and microalbuminuria.
Those gene variants could contribute to inter-individual
differences in susceptibility to and outcome of essential
hypertension. Therefore, the major challenge in cardiovascular
medicine is to find a way of predicting the risk
of hypertension complications by genetic markers that,
used with imaging techniques, could lead to the development
of new and better diagnostic and therapeutic
methods.

C-reactive protein is not related to ambulatory blood pressure or target organ damage in treated hypertensives
Background Publication of the JUPITER trial has renewed the interest in the use of CRP in cardiovascular risk prediction. The aim of the study was to assess the relationship between CRP, ambulatory blood pressure and target organ damage in a cohort of treated hypertensive males without overt cardiovascular disease.Materials and methods The studied group consisted of 299 male hypertensive patients. Patients were stratified into low (≤ 2 mg/L), intermediate (2–5 mg/L), and high (> 5 mg/L) CRP groups. We measured ambulatory blood pressure, pulse wave velocity, left ventricular function and structure, carotid intima media thickness and ankle-brachial index.Results Twenty-six percent of the patients had CRP in the range of 2 to 5 mg/L, and 12% had CRP levels exceeding 5 mg/L. Ambulatory blood pressure and heart rate were not different across the three groups. Patients with high CRP had lower HDL cholesterol levels and higher plasma fibrinogen levels. Carotid femoral pulse wave velocity, carotid intima media thickness and ankle-brachial index were not different across the three groups. Echocardiographic data were also not related to the CRP level.Conclusions1. Elevated levels of CRP are frequently observed among treated patients with hypertension.2. CRP elevation is associated with higher fibrinogen and glucose levels, and lower HDL cholesterol independently of obesity and smoking status.3. Elevated CRP levels are not related to ambulatory blood pressure profile or target organ damage severity.4. Our findings are consistent with the concept that CRP measurement is of limited value in cardiovascular assessment.Background Publication of the JUPITER trial has renewed the interest in the use of CRP in cardiovascular risk prediction.

The abdominal obesity prevalence among hypertensives patients in Poland — the consequence of diagnostic criteria change in new Polish Society of Hypertension 2011 guidelines
Wstęp Nadciśnienie tętnicze i otyłość brzuszna są
jednymi z czynników ryzyka sercowo-naczyniowego.
Istnieją dwie równoległe definicje otyłości
brzusznej. Third Report of the National Cholesterol
Education Program Expert Panel on Detection, Evaluation,
and Treatment of High Blood Cholesterol in
Adults (ATP III) zaleca rozpoznawanie otyłości przy
obwodzie pasa powyżej 102 cm dla mężczyzn i powyżej
88 cm dla kobiet, natomiast International Diabetes
Federation (IDF) odpowiednio: 94 cm i poniżej
80 cm. W nowych wytycznych Polskiego Towarzystwa
Nadciśnienia Tętniczego przyjęto definicję proponowaną
przez IDF. Celem pracy było określenie
wpływu zmiany kryteriów rozpoznawania otyłości
brzusznej na częstość jej występowania u chorych
z nadciśnieniem tętniczym.
Materiał i metody Pacjentom zgłaszającym się do
wybranych gabinetów lekarzy rodzinnych w ramach
badania IDEA wykonano badanie podmiotowe
i przedmiotowe, w tym pomiar obwodu pasa, według
standardów obowiązujących we wszystkich
ośrodkach. Analizowano częstość występowania otyłości
brzusznej wśród osób z nadciśnieniem tętniczym
według kryteriów ATP III oraz IDF.
Wyniki Zbadano 5371 osób (2024 mężczyzn, 3347
kobiet). Według kryteriów ATP III otyłość brzuszną
stwierdzono u 36,7% kobiet bez nadciśnienia tętniczego
oraz u 75,5% z nadciśnieniem tętniczym (p <
0,001); wśród mężczyzn odpowiednio u 23,1% oraz
54% (p < 0,001). Według kryteriów IDF otyłość
brzuszna występowała u 60,9% kobiet bez nadciśnienia
tętniczego oraz 91,2% kobiet z nadciśnieniem
tętniczym (p < 0,001) oraz u mężczyzn odpowiednio
u 51,1% oraz 80,2% (p < 0,001). Stosowanie
kryteriów IDF spowodowało wzrost częstości otyłości
brzusznej wśród chorych z nadciśnieniem tętniczym
z 67,2% do 86,9%. Zarówno dla kryteriów ATP
III oraz IDF częstość otyłości brzusznej wzrastała
z wiekiem do 70. roku życia u kobiet z nadciśnieniem
tętniczym. W grupie mężczyzn zależność ta
istniała jedynie dla kryteriów ATP III. Różnice częstości
występowania otyłości brzusznej dla obu kryteriów
były znamienne we wszystkich przedziałach
wiekowych, szczególnie w młodszych grupach.
Wnioski Nieprawidłową masę ciała stwierdza się
u 2/3 osób zgłaszających się do lekarza. Otyłość
brzuszna, według ATP III, występuje dwukrotnie
częściej u chorych z nadciśnieniem tętniczym niż
z prawidłowym ciśnieniem tętniczym. Kryteria IDF
prowadzą do wzrostu częstości występowania otyłości
brzusznej wśród chorych z nadciśnieniem tętniczym
z 67,2% do 86,9%.
Nadciśnienie Tętnicze 2011, tom 15, nr 3, strony 155–162.Background Hypertension and visceral obesity are major
cardiovascular risk factors. There are two parallel definitions
of abdominal obesity — the ATP III defines abdominal
obesity as a waist circumference more than 102 cm
for men and 88 cm for women, whereas the IDF criteria
are 94 cm for men and 80 cm for women. In new PTNT
guidelines, the IDF criteria are recommended. The aim
of our paper is to asses the influence of change in definition
on abdominal obesity prevalence among hypertensive
patients.
Material and methods We studied consecutive patients
visiting general practitioners enrolled into the IDEA Study.
Subjects underwent physical examination with waist circumference
assessment. The prevalence of abdominal
obesity among hypertensives was analyzed according to
the ATP III and IDF criteria.
Results Fife thousand three hundred seventy one patients
were included into the study (2024 men, 3347 women).
According to the ATP criteria, visceral obesity was more
prevalent in hypertensives than in normotensives (75.5%
vs. 36.7% in women, and 54.0% vs. 23.1 in men; p < 0.001
for both comparisons). Similarly, hypertension was associated
with higher prevalence of visceral obesity when IDF
criteria were used (91.2% vs. 60.9% in women, and 80.2%
vs. 51.1 in men; p < 0.001 for both comparisons). Application
of IDF criteria increased abdominal obesity prevalence
increase among hypertensives from 67.2% to 86.9%.
Application of both ATP III and IDF criteria resulted in
significant increase in prevalence of abdominal obesity
among hypertensive women in all age groups, whereas for
men it was true only for the ATP III criteria. The difference
between abdominal obesity prevalence according to
the ATP III and IDF criteria was significant in all age
groups, especially among younger patients.
Conclusions Two thirds of Polish patients are either overweight
or obese. Abdominal obesity, according to ATP III
criteria is twice more prevalent among hypertensives than
subjects with normal blood pressure. The application of
IDF criteria increases abdominal obesity prevalence among
Polish hypertensives from 67.2% to 86.9%.
