BACKGROUND: Low splanchnic perfusion is an immediate effect of pneumoperitoneum-induced intra-abdominal hypertension (IAH). Anatomical structure results in the intestinal mucosa being the area most sensitive to hypoperfusion. The relationship between intestinal injury and clinical parameters of tissue perfusion [abdominal perfusion pressure (APP), gastric intramucosal pH (pHi ) and lactic acid (Lc)] has not been previously studied. This study aimed to monitorize intestinal pathogenesis through sequential ileal biopsies and to measure APP, pHi , and Lc levels at different pneumoperitoneum-induced intra-abdominal pressures (20, 30, and 40 mmHg) to evaluate the potential relationships between them...

INTRODUCTION: Home sleep apnea testing (HSAT) is a diagnostic measure for obstructive sleep apnea hypopnea syndrome (OSAHS) in moderate/high risk patients. Some HSAT companies contain automatic analysis (AA). However, guidelines recommend manual analysis (MA) despite the weak evidence for this recommendation. OBJECTIVE: Evaluate the concordance between AA and MA of HSAT to make either a diagnosis and severity classification. METHODS: We evaluated AA and MA of HSAT between 2015 and 2016...

AIMS/HYPOTHESIS: Impaired awareness of hypoglycaemia (IAH) in type 1 diabetes increases the risk of severe hypoglycaemia sixfold and can be resistant to intervention. We explored the impact of IAH on central responses to hypoglycaemia to investigate the mechanisms underlying barriers to therapeutic intervention. METHODS: We conducted [15 O]water positron emission tomography studies of regional brain perfusion during euglycaemia (target 5 mmol/l), hypoglycaemia (achieved level, 2...

Administration of lactate during hypoglycemia suppresses symptoms and counterregulatory responses, as seen in patients with type 1 diabetes and impaired awareness of hypoglycemia (IAH), presumably because lactate can substitute for glucose as a brain fuel. Here, we examined whether lactate administration, in a dose sufficient to impair awareness of hypoglycemia, affects brain lactate levels in patients with normal awareness of hypoglycemia (NAH). Patients with NAH ( n = 6) underwent two euglycemic-hypoglycemic clamps (2...

The Independence at Home (IAH) Demonstration Year 2 results confirmed that the first-year savings were 10 times as great as those of the pioneer accountable care organizations during their initial 2 years. We update projected savings from nationwide conversion of the IAH demonstration, incorporating Year 2 results and improving attribution of IAH-qualified (IAH-Q) Medicare beneficiaries to home-based primary care (HBPC) practices. Applying IAH qualifying criteria to beneficiaries in the Medicare 5% claims file, the effect of expanding HBPC to the 2...

REVIEW
Alison D McNeilly, Rory J McCrimmon
Hypoglycaemia remains the most common metabolic adverse effect of insulin and sulfonylurea therapy in diabetes. Repeated exposure to hypoglycaemia leads to a change in the symptom complex that characterises hypoglycaemia, culminating in a clinical phenomenon referred to as impaired awareness of hypoglycaemia (IAH). IAH effects approximately 20-25% of people with type 1 diabetes and increases the risk of severe hypoglycaemia. This review focuses on the mechanisms that are responsible for the much higher frequency of hypoglycaemia in people with diabetes compared with those without, and subsequently how repeated exposure to hypoglycaemia leads to the development of IAH...

AIMS: To investigate fear of hypoglycaemia (FoH) in relation to hypoglycaemia awareness, history of severe hypoglycaemia (SH) and hypoglycaemia symptoms in adults with Type 1 diabetes. METHODS: Questionnaire-based cross-sectional survey. We assessed FoH with the Hypoglycaemia Fear Survey-II Worry subscale, hypoglycaemia awareness status with the Gold score, and used the Edinburgh Hypoglycaemia Scale to grade the presence and intensity of hypoglycaemia symptoms. All these measures have previously been validated for research application...

Natasa Kovac, Mladen Peric
BACKGROUND AND OBJECTIVE: Liver function assessment in patients with intra-abdominal hypertension (IAH) after major abdominal surgery is complex and often confounding. Elevated intra-abdominal pressure (IAP) often occurs after major abdominal surgery, and is associated with decreased abdominal blood flow and organ dysfunction, and it could cause abdominal compartment syndrome (ACS), which is a life-threatening condition. Plasma disappearance rate (PDR) of indocyanine green (ICG) and ICG retention rate after 15 min (R15) were used to evaluate liver function and as a prognostic parameter after major abdominal surgery...

BACKGROUND: A mechanical intestinal obstruction (MIO) can generate intraabdominal hypertension (IAH) that is life threatening. The intestines are very sensitive to IAH since the low splanchnic perfusion causes intestinal hypoxia, local acidosis and bacterial translocations. This may lead to acute intestinal distress syndrome (AIDS). The identification of intestinal injuries during IAH and its correlation with clinical parameters as the abdominal perfusion pressure (APP), the gastric intramucosal pH (pHi) and lactic acid (Lc) are still unknown...

Some patients with intra-abdominal infection (IAI) may develop intra-abdominal hypertension (IAH) during treatment. The present study investigated the impact of IAI combined with IAH on the intestinal mucosal barrier in a rabbit model. Forty-eight New Zealand white rabbits were randomly divided into four groups: (i) IAI and IAH; (ii) IAI alone; (iii) IAH alone; and (iv) Control group. IAI model: cecal ligation and puncture for 48 h; IAH model: raised intra-abdominal pressure (IAP) of 20 mmHg for 4 h. Pathological changes in intestinal mucosa were confirmed by light and scanning electron microscopy...

BACKGROUND: Intra-abdominal hypertension is a common complication in critically ill patients. Recently the Abdominal Compartment Society (WSACS) developed a medical management algorithm with a stepwise approach according to the evolution of the intra-abdominal pressure and aiming to keep IAP ≤ 15 mm Hg. With the increased use of ultrasound as a bedside modality in both emergency and critical care patients, we hypothesized that ultrasound could be used as an adjuvant point-of-care tool during IAH management...

Intra-abdominal hypertension (IAH) is a frequent and serious condition affecting critical care patients. IAH diagnostic needs intravesical pressure (IVP) measurement which is recommended for monitoring patients presenting IAH risk factors. IVP monitoring is probably insufficient in daily practice. This could be explained by lack of knowledge about IAH physiopathology, which leads to absence of therapeutic target. Acute kidney injury (AKI) is the earliest and most described organ dysfunction associated with IAH...

Intra-abdominal hypertension (IAH) is common in critically ill patients. Diagnosis is based on measurement of intra-abdominal pressure, most commonly via the bladder. Modern imaging techniques with plain radiographs, computed tomography and magnetic resonance can help establish the diagnosis and also guide treatment. In 2013 the Abdominal Compartment Society (WSACS) published updated consensus definitions and recommendations for management of IAH and abdominal compartment syndrome (ACS). This review will give a concise overview of the important role radiographic imaging plays within these management guidelines...

BACKGROUND: Severe burns have been shown to be a risk factor for developing intra-abdominal hypertension (IAH). Fluid resuscitation practices used in burns management further predispose patients to intra-abdominal hypertension. The mortality associated with IAH in severe burns is estimated to be more than 74.5% once organ dysfunction occurs. Despite 95% of all burns occurring in Low and Middle income countries (LMIC), there is paucity of published data on this topic in sub-Saharan Africa...

PURPOSE: Intra-abdominal hypertension (IAH) is associated with impaired respiratory function. Animal data suggest that positive end-expiratory pressure (PEEP) levels adjusted to intra-abdominal pressure (IAP) levels may counteract IAH-induced respiratory dysfunction. In this pilot study, our aim was to assess whether PEEP adjusted for IAP can be applied safely in patients with IAH. MATERIALS AND METHODS: We included patients on mechanical ventilation and with IAH...
