Perception of improvement after orthognathic surgery: the important variables affecting patient satisfaction

PURPOSE: We evaluated which factors affect patient satisfaction and if patient expectations were fulfilled after orthognathic surgery. METHODS: Questionnaires consisting of 14 questions were given 1 year after bimaxillary osteotomy for class-III correction to subjects. Six questions were answered using an 11-point rating scale based on a visual analog scale (VAS; 0 = poor; 10 = excellent). Also included were seven closed-form questions with yes/no answers, as well as one open question for 'further remarks'. Sagittal and vertical cephalometric parameters were determined on postoperative cephalograms. RESULTS: Seventy-seven patients (37 females, 40 males; mean age, 23.4 +/- 4.9 (SD) years) responded. The intention to undergo surgery only for aesthetic improvement was noted in 11.9% of patients; only improvement of chewing function in 15.5%; both in 71.4%; and none/don't know in 2.6%. Postoperative satisfaction was rated (in means) with 8.13 +/- 1.97 on VAS and correlated significantly with the opinions of friends and relatives. Facial aesthetics was rated 5.6 +/- 1.2 before surgery and 8.1 +/- 1.5 after surgery (p = 0.04). Preoperative chewing function was rated 5.65 +/- 1.8 and 8.03 +/- 1.51 after surgery (p = 0.014). TMJ disorders or hypoesthesia had no negative impacts. Cephalometric analyses revealed a significantly lower SNB (75.3 degrees +/- 2.7 degrees ; p = 0.033) in patients rating lower than grade 7 for overall satisfaction. For SNA and ArGoMe, no significant differences were observed. CONCLUSION: The most distinctive factors for patient satisfaction after orthognathic surgery were chewing function and facial aesthetics with respect to the lower face. Function, aesthetics, and even psychological aspects should be considered equally when planning surgery

Surviving Sepsis Campaign: international guidelines for management of severe sepsis and septic shock, 2012

OBJECTIVE: To provide an update to the "Surviving Sepsis Campaign Guidelines for Management of Severe Sepsis and Septic Shock," last published in 2008. DESIGN: A consensus committee of 68 international experts representing 30 international organizations was convened. Nominal groups were assembled at key international meetings (for those committee members attending the conference). A formal conflict of interest policy was developed at the onset of the process and enforced throughout. The entire guidelines process was conducted independent of any industry funding. A stand-alone meeting was held for all subgroup heads, co- and vice-chairs, and selected individuals. Teleconferences and electronic-based discussion among subgroups and among the entire committee served as an integral part of the development. METHODS: The authors were advised to follow the principles of the Grading of Recommendations Assessment, Development and Evaluation (GRADE) system to guide assessment of quality of evidence from high (A) to very low (D) and to determine the strength of recommendations as strong (1) or weak (2). The potential drawbacks of making strong recommendations in the presence of low-quality evidence were emphasized. Recommendations were classified into three groups: (1) those directly targeting severe sepsis; (2) those targeting general care of the critically ill patient and considered high priority in severe sepsis; and (3) pediatric considerations. RESULTS: Key recommendations and suggestions, listed by category, include: early quantitative resuscitation of the septic patient during the first 6 h after recognition (1C); blood cultures before antibiotic therapy (1C); imaging studies performed promptly to confirm a potential source of infection (UG); administration of broad-spectrum antimicrobials therapy within 1 h of the recognition of septic shock (1B) and severe sepsis without septic shock (1C) as the goal of therapy; reassessment of antimicrobial therapy daily for de-escalation, when appropriate (1B); infection source control with attention to the balance of risks and benefits of the chosen method within 12 h of diagnosis (1C); initial fluid resuscitation with crystalloid (1B) and consideration of the addition of albumin in patients who continue to require substantial amounts of crystalloid to maintain adequate mean arterial pressure (2C) and the avoidance of hetastarch formulations (1B); initial fluid challenge in patients with sepsis-induced tissue hypoperfusion and suspicion of hypovolemia to achieve a minimum of 30 mL/kg of crystalloids (more rapid administration and greater amounts of fluid may be needed in some patients (1C); fluid challenge technique continued as long as hemodynamic improvement is based on either dynamic or static variables (UG); norepinephrine as the first-choice vasopressor to maintain mean arterial pressure ≥65 mmHg (1B); epinephrine when an additional agent is needed to maintain adequate blood pressure (2B); vasopressin (0.03 U/min) can be added to norepinephrine to either raise mean arterial pressure to target or to decrease norepinephrine dose but should not be used as the initial vasopressor (UG); dopamine is not recommended except in highly selected circumstances (2C); dobutamine infusion administered or added to vasopressor in the presence of (a) myocardial dysfunction as suggested by elevated cardiac filling pressures and low cardiac output, or (b) ongoing signs of hypoperfusion despite achieving adequate intravascular volume and adequate mean arterial pressure (1C); avoiding use of intravenous hydrocortisone in adult septic shock patients if adequate fluid resuscitation and vasopressor therapy are able to restore hemodynamic stability (2C); hemoglobin target of 7-9 g/dL in the absence of tissue hypoperfusion, ischemic coronary artery disease, or acute hemorrhage (1B); low tidal volume (1A) and limitation of inspiratory plateau pressure (1B) for acute respiratory distress syndrome (ARDS); application of at least a minimal amount of positive end-expiratory pressure (PEEP) in ARDS (1B); higher rather than lower level of PEEP for patients with sepsis-induced moderate or severe ARDS (2C); recruitment maneuvers in sepsis patients with severe refractory hypoxemia due to ARDS (2C); prone positioning in sepsis-induced ARDS patients with a PaO (2)/FiO (2) ratio of ≤100 mm Hg in facilities that have experience with such practices (2C); head-of-bed elevation in mechanically ventilated patients unless contraindicated (1B); a conservative fluid strategy for patients with established ARDS who do not have evidence of tissue hypoperfusion (1C); protocols for weaning and sedation (1A); minimizing use of either intermittent bolus sedation or continuous infusion sedation targeting specific titration endpoints (1B); avoidance of neuromuscular blockers if possible in the septic patient without ARDS (1C); a short course of neuromuscular blocker (no longer than 48 h) for patients with early ARDS and a PaO (2)/FI O (2) 180 mg/dL, targeting an upper blood glucose ≤180 mg/dL (1A); equivalency of continuous veno-venous hemofiltration or intermittent hemodialysis (2B); prophylaxis for deep vein thrombosis (1B); use of stress ulcer prophylaxis to prevent upper gastrointestinal bleeding in patients with bleeding risk factors (1B); oral or enteral (if necessary) feedings, as tolerated, rather than either complete fasting or provision of only intravenous glucose within the first 48 h after a diagnosis of severe sepsis/septic shock (2C); and addressing goals of care, including treatment plans and end-of-life planning (as appropriate) (1B), as early as feasible, but within 72 h of intensive care unit admission (2C). Recommendations specific to pediatric severe sepsis include: therapy with face mask oxygen, high flow nasal cannula oxygen, or nasopharyngeal continuous PEEP in the presence of respiratory distress and hypoxemia (2C), use of physical examination therapeutic endpoints such as capillary refill (2C); for septic shock associated with hypovolemia, the use of crystalloids or albumin to deliver a bolus of 20 mL/kg of crystalloids (or albumin equivalent) over 5-10 min (2C); more common use of inotropes and vasodilators for low cardiac output septic shock associated with elevated systemic vascular resistance (2C); and use of hydrocortisone only in children with suspected or proven "absolute"' adrenal insufficiency (2C). CONCLUSIONS: Strong agreement existed among a large cohort of international experts regarding many level 1 recommendations for the best care of patients with severe sepsis. Although a significant number of aspects of care have relatively weak support, evidence-based recommendations regarding the acute management of sepsis and septic shock are the foundation of improved outcomes for this important group of critically ill patients

The evolving SARS-CoV-2 epidemic in Africa: Insights from rapidly expanding genomic surveillance

INTRODUCTION Investment in Africa over the past year with regard to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) sequencing has led to a massive increase in the number of sequences, which, to date, exceeds 100,000 sequences generated to track the pandemic on the continent. These sequences have profoundly affected how public health officials in Africa have navigated the COVID-19 pandemic. RATIONALE We demonstrate how the first 100,000 SARS-CoV-2 sequences from Africa have helped monitor the epidemic on the continent, how genomic surveillance expanded over the course of the pandemic, and how we adapted our sequencing methods to deal with an evolving virus. Finally, we also examine how viral lineages have spread across the continent in a phylogeographic framework to gain insights into the underlying temporal and spatial transmission dynamics for several variants of concern (VOCs). RESULTS Our results indicate that the number of countries in Africa that can sequence the virus within their own borders is growing and that this is coupled with a shorter turnaround time from the time of sampling to sequence submission. Ongoing evolution necessitated the continual updating of primer sets, and, as a result, eight primer sets were designed in tandem with viral evolution and used to ensure effective sequencing of the virus. The pandemic unfolded through multiple waves of infection that were each driven by distinct genetic lineages, with B.1-like ancestral strains associated with the first pandemic wave of infections in 2020. Successive waves on the continent were fueled by different VOCs, with Alpha and Beta cocirculating in distinct spatial patterns during the second wave and Delta and Omicron affecting the whole continent during the third and fourth waves, respectively. Phylogeographic reconstruction points toward distinct differences in viral importation and exportation patterns associated with the Alpha, Beta, Delta, and Omicron variants and subvariants, when considering both Africa versus the rest of the world and viral dissemination within the continent. Our epidemiological and phylogenetic inferences therefore underscore the heterogeneous nature of the pandemic on the continent and highlight key insights and challenges, for instance, recognizing the limitations of low testing proportions. We also highlight the early warning capacity that genomic surveillance in Africa has had for the rest of the world with the detection of new lineages and variants, the most recent being the characterization of various Omicron subvariants. CONCLUSION Sustained investment for diagnostics and genomic surveillance in Africa is needed as the virus continues to evolve. This is important not only to help combat SARS-CoV-2 on the continent but also because it can be used as a platform to help address the many emerging and reemerging infectious disease threats in Africa. In particular, capacity building for local sequencing within countries or within the continent should be prioritized because this is generally associated with shorter turnaround times, providing the most benefit to local public health authorities tasked with pandemic response and mitigation and allowing for the fastest reaction to localized outbreaks. These investments are crucial for pandemic preparedness and response and will serve the health of the continent well into the 21st century

مصريون قلباﹰ .. فرانكوفونيون قالباﹰ: شهادة شخصية / Egyptian Heart, French Tongue: A Personal Tetimony

[The author of this essay, a prominent Egyptian writer, recalls Egyptian Francophone writers based on his encounters with them and/or reading their works. He provides Arabic translations of excerpts from their works to illustrate his points. Albert Cossery-whom he read when he was still a teenager, and met later in Paris- is identified as a precursor of the philosophical absurd. Al-Kharrat is fascinated by Cossery\u27s fantastic realism, surrealism, black humor and the depiction of popular Cairo. Cossery\u27s Francophone texts have an Egyptian lining-a contradictory feat that only art and life can exhibit simultaneously. Ahmed Rassim, another Francophone writer, translated Arabic proverbs and celebrated the Egyptianness of the artist Mahmud Sa\u27id. Rassim\u27s poetics with its contrived beauty runs against that of Joyce Mansour with its powerful and wild magic. The excess of Mansour is seen as a trait typical of Upper Egypt and of religious art and architecture in Coptic icons and Islamic shrines. Moving to George Henein, al-Kharrat asserts that Arabic is the latent language in the French text. Finally, al-Kharrat writes about Edmond Jabès who moved to France in the mid fifties, but never felt at home there. Al-Kharrat quotes Jabès about his roots in Egypt and his rejection of Israel as a solution for him. Jabès challenges to time are akin to those of the Pharaohs. Al-Kharrat finds correspondence between the trans-genre writing which he has espoused and Jabès\u27 multi-genre texts combining aphorisms, poetry, prose and parables. Al-Kharrat argues that the surrealism of the 1940s in Egypt whcih was spearheaded by Francophone writers had remained dormant until the 1970s when it was revived by Egyptian writers in Arabic.

تباريح وقائع هندية قديمة / Yearnings for Bygone Indian Encounters

[The Egyptian novelist, al-Karrat, who has been an active member of the Afro-Asian Peoples\u27 Solidarity Organization and the Afro-Asian Writers\u27 Association, recalls in this testimony encounters and events in his personal life associated with India. In a lyrical and passionate outpouring al-Kharrat opens up his Indian recollections with his early reading of the poetry of Rabindranath Tagore, first in Arabic translation and later in English. The poetry of Tagore was a close companion of al-Kharrat when he was detained for political activities in the late 1940s. Then al-Kharrat discovered Mulk Raj Anand\u27s fiction and admired the Indian author\u27s characterization of the dispossessed. Encounters with other younger poets and women poets from different parts of India are also affectionately mentioned. Some of their poetry has been translated into Arabic by al-Kharrat. Along with his literary reminiscences, al-Kharrat describes his many visits to India. Sensuous souks, aggressive hustlers, sumptuous meals, sublime music, erotic sculpture and demeaning poverty are all seen in terms of their impact on the beholder al-Kharrat. They invariably conjure correspondences with Egyptian places and cities: Karnak, Ghouriyya, Alexandria, a nd Tanta among others. Al-Kharrat\u27s recollections of his visits to India are intertwined with a story of a passionate encounter whose intimacies are lyrically presented against the beauty and magic of India. The female figure in the encounter is present also in al-Kharrat\u27s semi-autobiographical trilogy. Using the poetics of fragmentation, al-Kharrat recalls past events imaginatively: memory and desire, India and poetry, unrequited love and sensual excess, overlap in his mind. Calcutta, Bombay and New Delhi, the culturally rich cities, were the setting of an enduring passion. The diversity-in-oneness of the woman he calls Isis, Aphrodite and Rama is what he finds captured in a wooden statue of a nude in the Indian bazaar. For him, India is the land of The One Thousand and One Nights. In this voyage, simultaneously out and in, of al-Kharrat, fabulous India seems like the projection of an eye intent on contemplating equally the motifs of a carpet, the imagery of a poem and the gesture of the beloved. Prominent political figures, internationally renowned artists, emerging writers, lost friends are all in the fabric of this essay celebrating an India that stands for the land of struggles for integrity and freedom, the land of the joie de vivre and the joys of poetry, and the land of the dream of justice, as al-Kharrat puts it.
