This scientific study aims to evaluate the effects of bowel preparation on the outcomes of scheduled colorectal surgery. The study included a group of 83 patients, 37 without bowel preparation and 46 with bowel preparation. Perioperative outcomes of
patients were evaluated, including surgical site infection (SSI) rates, postoperative complications, and length of hospital stay.
The results concluded that bowel preparation before scheduled colorectal surgery has no superiority in reducing SSI and postoperative complications (anastomotic leakage, occurrence of abdominal or pelvic abscesses), as well as shortening the length of hospital stay, and did not show any clear advantage over the patients without mechanical bowel preparation.
Abstract Models for question answering, dialogue agents, and summarization often interpret the meaning of a sentence in a rich context and use that meaning in a new context. Taking excerpts of text can be problematic, as key pieces may not be explici
t in a local window. We isolate and define the problem of sentence decontextualization: taking a sentence together with its context and rewriting it to be interpretable out of context, while preserving its meaning. We describe an annotation procedure, collect data on the Wikipedia corpus, and use the data to train models to automatically decontextualize sentences. We present preliminary studies that show the value of sentence decontextualization in a user-facing task, and as preprocessing for systems that perform document understanding. We argue that decontextualization is an important subtask in many downstream applications, and that the definitions and resources provided can benefit tasks that operate on sentences that occur in a richer context.
The main objective of the study is to study the early results of the maintenance of the
pleura during the preparation of the internal breast artery in the maintenance of respiratory
function and its role in the prevention of respiratory and hemorrh
agic complications
following its opening and comparison with the global studies conducted in this area. The
study included patients with Cabg of both sexes aged between 40 years and 72 years of age
who were the EF% from 40% in Tishreen University Hospital in Lattakia as a prospective
study during 2017. The study included 30 patients divided into two groups: Fifteen patients
had closed their pleura, and the second group (15) patients had pleural ulcers. Patients were
followed within one week after surgery. We conclude from our study that hemorrhagic
complications and need for blood transfusions and respiratory complications were
significantly less when maintaining the pleura closed in the first group.
This study aimed to evaluate the extent of the
microleakage in the cavities which prepared with Er:YAG (erbium:
yttrium aluminum garnet) laser or diamond burs and restored by
using of different types of resin materials.
Aim: to compare the shaping ability of two rotary systems (Protaper Universal and
Protaper Next) and K-file hand instruments in curved root canals of extracted human
molars.
Materials and methods:Thirty extracted molars with curved canals were cho
sen. The
curvature of root canals was determined (15-40o) then the sample was randomly divided
into three groups: n1=n2=n3=10. Group(1): was prepared using K-file hand instruments
(Stand), group(2): prepared by Protaper Universal (PTU), whereas group3: prepared by
Protaper Next (PTN).The curvature after preparation and Time preparationwere evaluated.
Data were collected and statistical analysis was conducted.
Results: The three instrument systems (PTU, PTN, Stand) have caused significant
change in original canal curvature(P<0.05). On the other hand, there were no significant
differences between systemsin straightening of canal curvature (P>0.05). However, both
systems: PTN, Stand were significantly faster than PTU during preparation of curved
canals (P<0,001).Conclusion: under the conditions of this study, it can be concluded
thatall instruments caused changing in original canal curvature. However, the new
generation PTN was faster than old one PTU.
Phenol derivatives have been reacted with aryl halides under
heterogeneous basic catalyst (Amberlyst-21) using 5 mol% Cu(I)
Complex as catalyst, [CuClPPh3]4. The typical reaction has been
performed between p-cresol and bromobenzene. This reaction
is
achieved in o-xylene as solvent. However, the catalyst complex
does not dissolve in toluene rather it acts as heterogeneous catalyst.
Therefore, it is filtrated at the end of the reaction and reused several
times. Accordingly, new compounds were prepared by reacting one
of the bromoaryl derivatives with paracetamol. It is anticipated that
the synthesized compounds may have pharmaceutical application as
non-steroidial anti-inflammatory drugs (NSAIDs).
