Objective: To unravel the effects of different laparoscopic inguinal hernia repairs (IHRs) on inflammatory factors, oxidative stress, and postoperative recovery of inguinal hernia (IH) patients.
Methods: A total of 88 patients for laparoscopic treatment of IH were studied in a retrospective cohort, and were randomized into the transabdominal preperitoneal (TAPP) repair group (n = 44) and the total extraperitoneal (TEP) repair group (n = 44) according to the method of treatment. Patients in the TAPP group underwent laparoscopic TAPP IHR, while patients in the TEP group underwent laparoscopic TEP IHR. Visual analogue scores (VAS) were measured at 1, 3, and 7 d after repair. Gastrin (GAS), motilin (MTL), matrix metalloproteinase (MMP)-2, MMP-9, and tissue inhibitor of metalloproteinases-1 (TIMP-1) were assessed by enzyme-linked immunosorbent assay. Superoxide dismutase (SOD) was tested by spectrophotometry and malondialdehyde (MDA) and β-endorphin (β-EP) were examined by radioimmunoprecipitation. Total antioxidant capacity (T-AOC) was evaluated by chemical colorimetry, quality of life was evaluated by SF-36, and fibrinogen (FIB), C-reactive protein (CRP), antitrypsin (al-AT), and interleukin-6 (IL-6) levels were determined by immunoturbidimetry. Complications and postoperative recurrence were recorded.
Results: VAS scores in the TEP group were lower than those in the TAPP group. Operative time, hospital stay, time for postoperative activity out of bed, and time taken to exhaust were shorter in the TEP group than in the TAPP group. Intraoperative blood loss was less in the TEP group than in the TAPP group. GAS, MTL, SOD, and T-AOC were higher, and MDA, β-EP, CRP, FIB, alAT, IL-6, MMP-2, MMP-9, and TIMP-1 were lower in the TEP group than the TAPP group. Quality of life was improved in the TEP group compared with the TAPP group. There was no significant difference in the rate of postoperative complications and recurrence rates between both groups of patients.
Conclusion: For IHs, laparoscopic TEP repair can effectively relieve pain, reduce inflammatory factors and oxidative stress indices, and facilitate postoperative recovery.

The impact of COPD screening on US primary care clinician behavior and patient outcomes is unclear. Assess the impact of receiving CAPTURE (COPD Assessment in Primary Care to Identify Undiagnosed Respiratory Disease and Exacerbation Risk) screening scores on clinical and patient outcomes. Cluster randomized trial included 49 usual care (COPD education only) and 51 intervention (COPD and CAPTURE education plus screening scores) primary care practices.

Patients And Methods: Materials and Methods: The study included 76 patients (average age 61,4±15,3 years; 69 [91 %] males, 7 [9 %] females) with primary uncomplicated unilateral inguinal hernias who underwent TAPP. Patients were divided into two groups: group 1 - 52 patients in whom the AbsorbaTack fixation device was used to secure the mesh; group 2 - 24 patients in whom the LiquiBand FIX8 cyanoacrylate adhesive was used.
Impact of a reduced metabolizable protein supply during the transition period on the immune and metabolic status of dairy cows.

During the transition period, the incidence of diseases increases due to a negative energy balance that affects metabolic and immune status. Limiting milk production at the beginning of lactation by milking once a day or by incompletely milking twice a day improves the metabolic and immune status of cows. Previous studies have shown that milk production is highly responsive to additional MP.

There are a variety of repair methods, from open methods to laparoscopic approaches. The available laparoscopic techniques that exist for inguinal hernia repair are transabdominal preperitoneal (TAPP) repair and totally extraperitoneal (TEP) repair.

Aim: This work describes the validation of an in-house extraction free real-time polymerase chain reaction (PCR) for the detection of Group A Streptococcus (GAS) in throat swabs collected in gel amies.
Method: Throat swabs received by the laboratory were prospectively tested by routine bacterial culture and an in-house PCR assay targeting the GAS SpeB gene with a multiplexed RNaseP internal control. Samples with discrepant culture/PCR results had additional testing using the commercial Xpert Group A Strep PCR assay (Cepheid).
